This version of xdvi is also referred to as\nxdvik since it uses the kpathsea library to locate and generate font\nfiles. In addition to that, it supports the following features:\n\n- hyperlinks in DVI files (section HYPERLINKS),\n\n- direct rendering of PostScript Type 1 fonts (section TYPE 1\nFONTS),\n\n- source specials in the DVI file (section SOURCE SPECIALS),\n\n- string search in DVI files (section STRING SEARCH),\n\n- saving or printing (parts of) the DVI file (sections PRINT DIALOG\nand SAVE DIALOG).\n\nXdvi can be compiled with the Motif toolkit or the Xaw (Athena) toolkit\n(and variants of it), and the Motif version has a slightly different\nGUI; these differences are noted below.\n\nBefore displaying a page of a DVI file, xdvi will check to see if the\nfile has changed since the last time it was displayed. If this is the\ncase, it will reload the file. This feature allows you to preview many\nversions of the same file while running xdvi only once. Since it cannot\nread partial DVI files, xdvik versions starting from 22.74.3 will cre-\nate a temporary copy of the DVI file being viewed, to ensure that the\nfile can be viewed without interruptions. (The -notempfile can be used\nto turn off this feature).\n\nXdvi can show PostScript specials by any of three methods. It will\ntry first to use Display PostScript, then NeWS, then it will try to\nuse Ghostscript to render the images. All of these options depend on\nadditional software to work properly; moreover, some of them may not be\ncompiled into this copy of xdvi.\n\nFor performance reasons, xdvi does not render PostScript specials in\nthe magnifying glass.\n\nIf no file name has been specified on the command line, xdvi will try\nto open the most recently opened file; if the file history (accessible\nvia the File > Open Recent menu) is empty, or if none of the files in\nthe history are valid DVI files, it will pop up a file selector for\nchoosing a file name. (In previous versions, which didn't have a file\nhistory, the file selector was always used; you can set the X resource\nnoFileArgUseHistory to false to get back the old behaviour.)\n", "subsections": [] }, "OPTIONS": { "content": "In addition to specifying the dvi file (with or without the .dvi exten-\nsion), xdvi supports the following command line options. If the option\nbegins with a `+' instead of a `-', the option is restored to its de-\nfault value. By default, these options can be set via the resource\nnames given in parentheses in the description of each option.\n\n+page Specifies the first page to show. If + is given without a num-\nber, the last page is assumed; the first page is the default.\n", "subsections": [ { "name": "-allowshell", "content": "(.allowShell) This option enables the shell escape in PostScript\nspecials. (For security reasons, shell escapes are disabled by\ndefault.) This option should be rarely used; in particular it\nshould not be used just to uncompress files: that function is\ndone automatically if the file name ends in .Z, .gz, or .bz2.\nShell escapes are always turned off if the -safer option is\nused.\n\n-altfont font\n(.altFont) Declares a default font to use when the font in the\ndvi file cannot be found. This is useful, for example, with\nPostScript fonts.\n\n-anchorposition anchor\nJump to anchor after opening the DVI file. This is only useful\nwhen invoking xdvi from other applications.\n\n-background color\n(.background) Determines the color of the background. Same as\n-bg.\n\n-bg color\n(.background) Determines the color of the background.\n\n-browser browser\n(.wwwBrowser) Defines the web browser used for handling external\nURLs. The value of this option or resource has the same syntax\nas the BROWSER environment variable; see the explanation of that\nvariable in the section `ENVIRONMENT' below for a detailed de-\nscription. If neither the option nor the X resource wwwBrowser\nis specified, the environment variables BROWSER and WWWBROWSER\n(in that order) are used to determine the browser command. If\nthese are not set either, the following default value is used:\nxdg-open %s:htmlview %s:firefox -remote -remote \"openURL(%s,new-\nwindow)\":mozilla -remote \"openURL(%s,new-window)\":netscape\n-raise -remote \"openURL(%s,new-window)\":xterm -e w3m %s:xterm -e\nlynx %s:xterm -e wget %s\n\n-copy (.copy) Always use the copy operation when writing characters to\nthe display. This option may be necessary for correct operation\non a color display, but overstrike characters will be incorrect.\nIf greyscale anti-aliasing is in use, the -copy operation will\ndisable the use of colorplanes and make overstrikes come out in-\ncorrectly. See also -thorough.\n\n-cr color\n(.cursorColor) Determines the color of the mouse cursor. The\ndefault is the same as the foreground color.\n\n-debug bitmask|string[,string ...]\n(.debugLevel) If nonzero, prints additional information on stan-\ndard output. The argument can be either a bitmask specified as\na decimal number, or comma-separated list of strings.\nFor the bitmask representation, multiple values can be specified\nby adding the numbers that represent the individual bits; e.g.\nto debug all file searching and opening commands, use 4032 (=\n2048 + 1024 + 512 + 256 + 128 + 64). Use -1 to turn on debugging\nof everything (this will produce huge output).\nFor the string representation, use the strings listed in the\nfollowing table, with a comma to separate the values; e.g. to\ndebug all file searching and opening commands, use search,ex-\npand,paths,hash,stat,open. (The option `kpathsea' is provided\nas a shorthand for these.) Note that such a list may need to be\nquoted to prevent the shell from interpreting commas or spaces\nin the list.\nThe individual numbers and strings have the following meanings:\n\n1 bitmap Bitmap creation\n2 dvi DVI translation\n4 pk PK fonts\n8 batch Batch mode: Exit after\nreading the DVI file\n16 event Event handling\n32 ps PostScript interpreter calls\n64 stat Kpathsea stat(2) calls\n128 hash Kpathsea hash table lookups\n256 open Kpathsea file opening\n512 paths Kpathsea path definitions\n1024 expand Kpathsea path expansion\n2048 search Kpathsea searching\n4032 kpathsea All Kpathsea options\n4096 htex Hypertex specials\n8192 src Source specials\n16384 client Client/server mode (see -unique\nand -sourceposition options)\n32768 ft FreeType library messages (Type 1 fonts)\n65536 ftverbose Verbose FreeType library messages (currently unused)\n131072 gui GUI elements\n\nSome of the Kpathsea debugging options are actually provided by\nKpathsea; see the Debugging section in the Kpathsea manual for\nmore information on these.\n\n-density density\n(.densityPercent) Determines the density used when shrinking\nbitmaps for fonts. A higher value produces a lighter font. The\ndefault value is 40. If greyscaling is in use, this argument\ndoes not apply; use -gamma instead. See also the `S' keystroke.\nSame as -S.\n\n-display host:display\nSpecifies the host and screen to be used for displaying the dvi\nfile. By default this is obtained from the environment variable\nDISPLAY.\n\n-dvipspath path\n(.dvipsPath) Use path as the dvips program to use when printing.\nThe default for this is dvips. The program or script should\nread the DVI file from standard input, and write the PostScript\nfile to standard output.\n\n-editor editor\n(.editor) Specifies the editor that will be invoked when the\nsource-special() action is triggered to start a reverse search\n(by default via Ctrl-Mouse 1). The argument to this option is a\nformat string in which occurrences of ``%f'' are replaced by the\nfile name, occurrences of ``%l'' are replaced by the line number\nwithin the file, and optional occurrences of ``%c'' are replaced\nby the column number within the line.\n\nIf neither the option nor the X resource .editor is specified,\nthe following environment variables are checked to determine the\neditor command: XEDITOR, VISUAL, and EDITOR (in this sequence).\nIf the string is found as the value of the VISUAL or EDITOR en-\nvironment variables, then ``xterm -e '' is prepended to the\nstring; if the editor is specified by other means, then it must\nbe in the form of a shell command to pop up an X window with an\neditor in it. If none of these variables is set, a warning mes-\nsage is displayed and the command ``xterm -e vi +%l %f'' is\nused.\n\nIf no ``%f'' or ``%l'' occurs in the string, the missing format\nstrings are appended automatically. (This is for compatibility\nwith other programs when using one of the environment vari-\nables).\n\nA new instance of the editor is started each time this command\nis used; therefore it is preferable to use an editor that can be\ninvoked in `client' mode to load new files into the same in-\nstance. Example settings are:\n\nemacsclient --no-wait\n(older Emacsen)\n\ngnuclient -q\n(XEmacs and newer Emacsen)\n\ngvim --servername xdvi --remote\n(VIM v6.0+; the `--servername xdvi' option will cause\ngvim to run a dedicated instance for the files opened by\nxdvi.)\n\nnc (nedit)\n\nNote that those strings need to be enclosed into quotes when us-\ning them on the command-line to protect them from the shell;\nwhen using them as argument for the .editor resource in an X re-\nsource file, no quotes should be used.\n\nNOTE ON SECURITY: The argument of this option isn't executed as\na shell command, but via exec() to prevent evil tricks with the\ncontents of source specials.\n" }, { "name": "-expert", "content": "This option is only supported for backwards compatibility; it is\nequivalent to -expertmode 0, which should be preferred.\n\n-expertmode flag\n(.expertMode) With an argument of 0, this option switches off\nthe display of the buttons, scrollbars, the toolbar (Motif on-\nly), the statusline and the page list. These GUI elements can\nalso be (de)activated separately, by combining the appropriate\nvalues in the flag argument. This acts similar to the -debug op-\ntion: The integer flag is treated as a bitmap where each bit\nrepresents one element. If the bit has the value 1, the element\nis switched on, if it has the value 0, the element is switched\noff. The meaning of the bits is as follows:\n\n1 statusline\n2 scrollbars\n4 Motif: pagelist, Xaw: buttons and pagelist\n8 toolbar (Motif only)\n16 menubar (Motif only)\n\nFor example, to turn on only the statusline and the scrollbars,\nuse 3 (= 1 + 2). See also the `x' keystroke, where the bits are\naddressed by their positions, from 1 to 3 (Xaw) or 5 (Motif),\nrespectively.\n\nIf the statusline is not active, all messages that would normally be\nprinted to the statusline will be printed to stdout, unless the -hush-\nstdout option is used.\n\n-fg color\n(.foreground) Determines the color of the text (foreground).\n\n-findstring string\nThis option triggers a search for string in the DVI file men-\ntioned on the command-line, similar to forward search (see the\ndescription of the sourceposition option): If there is already\nanother instance of xdvi running on the displaying that DVI\nfile, it will cause that instance to perform the search instead.\nThe search starts at the top of the current page of the DVI\nfile.\n\n-font font\n(*font) Sets the font used in menus, buttons etc., as described\nin the X(7x) man page. The font for child windows can be set\nseparately, e.g.:\n\nxdvi*statusline*font: \\\n-*-helvetica-medium-r-*-*-12-*-*-*-*-*-*-*\n\n-foreground color\nSame as -fg.\n" }, { "name": "-fullscreen", "content": "When this option is used, xdvi will (try to) run in fullscreen\nmode, with no window decorations.

When using this option for presentations, you might want\nto get rid of all the control widgets as well, using the -ex-\npertmode option. This option can also be toggled at runtime us-\ning the fullscreen action (by default bound to Ctrl-l).\n\n-gamma gamma\n(.gamma) Controls the interpolation of colors in the greyscale\nanti-aliasing color palette. Default value is 1.0. For 0 <\ngamma < 1, the fonts will be lighter (more like the background),\nand for gamma > 1, the fonts will be darker (more like the fore-\nground).

This option is provided\nonly for backwards compatibility; the preferred way is to set\nboth the resolution and the Metafont mode via the -mfmode option\n(which see).\n\n-paper papertype\n(.paper) Specifies the size of the printed page. Note that in\nmost cases it's best to specify the paper size in the TeX input\nfile via the line\n\n\\usepackage[dvips]{geometry}\n\nwhich will be recognized by both dvips and xdvi; in that case\nthe use of a `-paper' option should be unnecessary.\nThe paper size may be specified in the form widthxheight option-\nally followed by a unit, where width and height are decimal num-\nbers giving the width and height of the paper, respectively, and\nthe unit is any of the two-letter abbreviations for units ac-\ncepted by TeX (pt, pc, in, bp, cm, mm, dd, cc, or sp). By de-\nfault, the unit is cm (centimeters).\nThere are also synonyms which may be used: us (8.5x11in), legal\n(8.5x14in), foolscap (13.5x17in), as well as the ISO sizes\na1-a7, b1-b7, c1-c7. Each of these also has a landscape or `ro-\ntated' variant: usr (11x8.5in), a1r-a7r, etc. For compatibility\nwith dvips, the formats letter (8.5x11in), ledger (17x11in) and\ntabloid (11x17in) are also supported (these don't have rotated\nvariants).\nAny of the above sizes may be preceded by a plus sign (`+');\nthis causes the paper size given here to override any paper size\ngiven in the dvi file. The default paper size is 21 x 29.7 cm\n(A4 size).\n\n-pause (.pause) This option provides a simple implementation of incre-\nmental (stepwise) display, which can be used for presentations.\nWhen this option is used, xdvi will pause the display of the\ncurrent page whenever it encounters a special special-string\n(xdvi:pause by default; the string can be customized via -paus-\nespecial, see below), and the cursor will change its shape. The\naction unpause-or-next() (by default bound to the Space key)\nwill display the next portion of the page up to the following\nspecial-string, or until the end of the page is reached. When\nthe option is not used, specials containing special-string will\nbe ignored.\n\n-pausespecial special-string\n(.pauseSpecial) Sets the special string that causes xdvi to\npause when the -pause option is active. The default value of\nspecial-string is xdvi:pause.\n\n-postscript flag\n(.postscript) If flag = 0, rendering of PostScript specials\nis disabled; instead, bounding boxes will be displayed (if\navailable). A value of 1 (the default) switches PostScript\nspecials on. With a value of 2, the PostScript specials are\ndisplayed along with their bounding boxes; this allows you to\nvisually check the correctness of the bounding boxes. The values\ncan also be toggled at runtime with the `v' keystroke and the\ncorresponding numerical prefix arguments 0, 1 and 2.\n\n-ps2pdfpath path\n(.ps2pdfPath) Use path as a conversion program from PostScript\nto PDF. The program or script should accept two command-line ar-\nguments: The PostScript file as first argument, and the PDF out-\nput file as second argument.\n\n-rulecolor color\n(.ruleColor) Determines the color of the rules used for the mag-\nnifier (default: foreground color).\n\n-q (.noInitFile) Ignore the $HOME/.xdvirc startup file (i.e. don't\nread it at startup, and don't write it at exit). This forces the\ndefaults defined in $HOME/.Xdefaults to be used. See FILES for\nmore information on $HOME/.xdvirc.\n\n-rv (.reverseVideo) Causes the page to be displayed with white char-\nacters on a black background, instead of vice versa.\n\n-S density\n(.densityPercent) Same as -density (which see).\n\n-s shrink\n(.shrinkFactor) Defines the initial shrink factor. The default\nvalue is 8. If shrink is given as 0, then the initial shrink\nfactor is computed so that the page fits within the window (as\nif the `s' keystroke were given without a number).\n\n-safer (.safer) This option turns on all available security options; it\nis designed for use when xdvi is called by a browser that ob-\ntains a dvi or TeX file from another site. This option selects\n+nogssafer and +allowshell.\n\n-sidemargin dimen\n(.sideMargin) Specifies the side margin (see -margins).\n\n-sourceposition line[:col][ ]filename\nThis option makes xdvi search in the dvi file for the place cor-\nresponding to the indicated line (and, optionally, column) in\nthe .tex source file, and highlight the place found by drawing a\nrectangle in the highlight color (see the -hl option) around the\ncorresponding text. In addition, when run with this argument\n(and the -nofork option is not given, which see), xdvi will al-\nways return immediately: if it finds another instance of xdvi\nalready showing dvifile, then it will cause that instance to\nraise its window and move to the given place in the dvi file;\notherwise it will start up its own instance in the background.\nIf several instances of xdvi are displaying the respective dvi\nfile, the instance which was last raised to the foreground will\nbe used.\n\nThe space before filename is only needed if the filename starts\nwith a digit. When the space is used, the argument needs to be\nenclosed in quotes to prevent the shell from misinterpreting the\nspace as argument separator.\n\nThis option requires that dvifile be prepared with source spe-\ncial information. See the section on SOURCE SPECIALS for de-\ntails on how to do this.\n\nHere is a more detailed description of how the filename in the\n-sourceposition argument is matched with the filename in the\nsource specials:\n\n1. If neither of the filenames contains a path name component,\nthe filenames are compared ignoring the `.tex' extensions in\nboth filenames.\n\n2. Otherwise, if one of the filenames does contain a path compo-\nnent (e.g.: ./test.tex, ../test.tex, /my/homedir/tex/test.tex\nor any combination of these), both filenames are expanded to\na full path, with any occurrences of ../ and ./ expanded, and\nmultiple slashes removed.\nThe pathname in the -sourceposition is expanded relative to\nthe current working directory of the xdvi -sourceposition in-\nvocation, and the pathnames in the source specials are ex-\npanded relative to the path of the current DVI file being\nviewed.\nThe path names are then compared ignoring the `.tex' exten-\nsions in both path names.\n" }, { "name": "-statusline", "content": "(.statusline) This option is obsolete; use -expertmode flag in-\nstead (which see).\n\n-text-encoding encoding\n(.textEncoding) Use encoding as the text encoding of the string\nin the \"Find\" window.

This prefix argument can be discarded by pressing the ``Es-\ncape'' key. If present, the ``Help'', ``Prior'' and ``Next'' keys are\nsynonyms for `?', `b', and `f' keys, respectively.\n\nThe key bindings listed here are those that xdvi assigns by default.\nThe names appearing in brackets at the beginning of the descriptions\nare the names of the actions associated with the keys; these can be\nused to customize the key bindings, as explained in more detail in the\nsection CUSTOMIZATION below. If only a lowercase binding is listed,\nboth upper- and lowercase keys will work for that binding.\n\nESC key\n[discard-number()] The escape key discards the numerical prefix\nfor all actions (useful when you mistyped a number).\n\nReturn key\n[forward-page()] Moves to the next page (or to the nth next page\nif a number is given). Synonyms are `n', `f' and Line Feed.\n\nBackspace key\n[back-page()] Moves to the previous page (or back n pages).\nSynonyms are `p', `b' and Ctrl-h.\n\nDelete key\n[up-or-previous()] Moves up two-thirds of a window-full, or to\nthe top of the previous page if already at the top of the page.\nWith a float argument, moves up the corresponding fraction of a\nwindow-full.\n\nSpace key\n[unpause-or-next()] Moves down two-thirds of a window-full, or\nto the next page if already at the bottom of the page.\nWhen the option -pause special-string is used and the display is\ncurrently paused, this key will instead display the next portion\nof the page until the next special-string or the end of the page\nis encountered. See the description of the -pause option for\ndetails.

With a prefix argument n, move for-\nward n history items.\n\n^ [home()] Move to the ``home'' position of the page. This is\nnormally the upper left-hand corner of the page, depending on\nthe margins as described in the -margins option, above.\n\n? [help()] Same as the h key (which see).\n\nB [htex-back()] This key jumps back to the previous hyperlink an-\nchor. See the section HYPERLINKS for more information on navi-\ngating the links.\n\nb [back-page()] Moves to the previous page (or back n pages).\nSynonyms are `p', Ctrl-h and Backspace.\n\nC [set-color()] This key toggles the use of color specials. The\nkey sequences `0C' and `1C' turn interpretation of color spe-\ncials off and on, respectively. See also the -nocolor option.\n\nc [center()] Moves the page so that the point currently beneath\nthe mouse cursor is moved to the middle of the window, and warps\nthe mouse cursor to the same place.\n\nD [toggle-grid-mode()] This key toggles the use of a grid on the\ndisplayed page. If no number is given, the grid mode is\nswitched on or off. By prepending a number from 1 to 3, 3 dif-\nferent grid levels can be set. The units of the grid are inches\nor centimeters, depending on whether the paper format is letter\n(in) or a4 (cm).\n\nd [down()] Moves page down two thirds of a window-full. With a\nfloat argument to ``down'', moves down the corresponding frac-\ntion of a window-full.\n\nCtrl-f [find()] Pop up a window to search for a string in the DVI file.\nSee the section STRING SEARCH, below, for more details.\n\nf [forward-page()] Moves to the next page (or to the nth next page\nif a number is given). Synonyms are `n', Return, and Line Feed.\n\nG [set-greyscaling()] This key toggles the use of greyscale anti-\naliasing for displaying shrunken bitmaps. In addition, the key\nsequences `0G' and `1G' clear and set this flag, respectively.\nSee also the -nogrey option.\n\nIf given a numeric argument that is not 0 or 1, greyscale anti-\naliasing is turned on, and the gamma resource is set to the val-\nue divided by 100. E.g. `150G' turns on greyscale and sets gamma\nto 1.5.\n\nCtrl-g [find-next()] Find the next match string in the DVI file; this\ncan be used instead of pressing the `Find' button in the search\nwindow.\n\ng [goto-page()] Moves to the page with the given number. If no\npage number is given, xdvi jumps to the last page.\nIf the option/resource useTeXpages is active, the numbers corre-\nspond to the actual page numbers in the TeX file; otherwise, ab-\nsolute page numbers (starting from 1) are used. In the latter\ncase, the page numbers can be changed with the `P' keystroke,\nbelow. Note that with the useTeXpages option it is possible\nthat the same page number occurs multiple times; in such a case,\nxdvi will use the first page number that matches.\n\nh Pops up a help window with a short explanation of the most im-\nportant key bindings and concepts.\n\nk [set-keep-flag()] Normally when xdvi switches pages, it moves to\nthe home position as well. The `k' keystroke toggles a `keep-\nposition' flag which, when set, will keep the same position when\nmoving between pages. Also `0k' and `1k' clear and set this\nflag, respectively. See also the -keep option.\n\nCtrl-l [fullscreen(toggle)] Toggles fullscreen mode (see the descrip-\ntion of the -fullscreen option for more information on this).\nThis is even more flaky than using the command-line option:\nThere is no universal standard how a window could change its own\ngeometry or window decorations at run-time, so this will not\nwork with most window managers or desktops. Generally, it's bet-\nter to use the window manager controls to change the size or\ndecorations of the xdvi window.\n\nl [left()] Moves page left two thirds of a window-full.\n\nM [set-margins()] Sets the margins so that the point currently un-\nder the mouse cursor defines the upper left-hand corner of the\ntext in the page. Note that the command does not move the im-\nage, but only determines the margins for the page switching com-\nmands. For details on how the margins are used, see the -margins\noption.\n\nm [toggle-mark()] Toggles the mark for the current page in the\npage list. When a page is marked, it is displayed with a small\nstar `*' next to the page number. The marked pages can then be\nprinted or saved to a file. A page or several pages can also be\nmarked by clicking or dragging Mouse-2 in the page list.\n\nCtrl-n [toggle-mark()forward-page()] Toggles the mark for the current\npage in the page list, and moves to the next page. This lets you\nquickly mark a series of subsequent pages.\n\nn [forward-page()] Moves to the next page (or to the nth next page\nif a number is given). Synonyms are `f', Return, and Line Feed.\n\nCtrl-o [select-dvi-file()] Read a new dvi file. A file-selection widget\nis popped up for you to choose the DVI file from. If a prefix\nargument n is given, the n th file from the file history is\nopened instead.\n\nP [declare-page-number()] ``This is page number n.'' This can be\nused to make the `g' keystroke refer to a different page number\nthan the physical page. (If you want to use `logical' or TeX\npage numbers instead of physical pages, consider using the op-\ntion -useTeXpages instead.) The argument n should be given as\nprefix to this key.\n\nCtrl-p [print()] Opens a popup window for printing the DVI file, or\nparts of it. See the section PRINT DIALOG for an explanation of\nthe options available, and the resources to customize the de-\nfault behaviour.\n\np [back-page()] Moves to the previous page (or back n pages).\nSynonyms are `b', Ctrl-h and Backspace.\n\nq [quit()] Quits the program.\n\nCtrl-r [forward-page(0)] Redisplays the current page.\n\nR [reread-dvi-file()] Forces the dvi file to be reread. This al-\nlows you to preview many versions of the same file while running\nxdvi only once.\n\nr [right()] Moves page right two thirds of a window-full.\n\nCtrl-s [save()] Opens a popup window for saving the DVI file, or parts\nof it. See the section SAVE DIALOG below for more information on\nthis.\n\nS [set-density()] Sets the density factor to be used when shrink-\ning bitmaps. This should be a number between 0 and 100; higher\nnumbers produce lighter characters. If greyscaling mode is in\neffect, this changes the value of gamma instead. The new value\nof gamma is the given number divided by 100; negative values are\nallowed.\n\ns [set-shrink-factor()] Changes the shrink factor to the given\nnumber. If no number is given, the smallest factor that makes\nthe entire page fit in the window will be used. (Margins are\nignored in this computation.)\n\nT [use-tex-pages()] Use logical TeX pages (the values of the\n\\count0 register) instead of physical pages for the pagelist la-\nbels and when jumping to a page in a document via goto-page().\nSee also the -useTeXpages option.\n\nt [switch-magnifier-units()] Switches the units used for the mag-\nnifier tick marks, and for reporting the distance between the\nmouse pointer and the ruler centre in ruler mode (see the sec-\ntion MODES). The default value is specified by the X resource\ntickUnits (`mm' by default). The units toggle through the fol-\nlowing values; except for `px', they all correspond to TeX's\nunits: mm (millimeters) pt (TeX points), in (inches), sp (scaled\npoints, the unit used internally by TeX) bp (big points or\n`PostScript points'), cc (cicero points), dd (didot points), pc\n(pica), and px (screen pixels).\n\nCtrl-u [back-page()toggle-mark()] Moves to the previous page, and tog-\ngles the mark for that page. This is the dual action to Ctrl-n.\n\nu [up()] Moves page up two thirds of a window-full. With a float\nargument to ``up'', moves up the corresponding fraction of a\nwindow-full.\n\nCtrl-v [show-source-specials()] Show bounding boxes for every source\nspecial on the current page, and print the strings contained in\nthese specials to stderr. With prefix 1, show every bounding box\non the page. This is for debugging purposes mainly.\n\nV [set-gs-alpha()] This key toggles the anti-aliasing of Post-\nScript specials when Ghostscript is used as renderer. In\naddition the key sequences `0V' and `1V' clear and set this\nflag, respectively. See also the -gsalpha option.\n\nv [set-ps()] This key toggles the rendering of PostScript spe-\ncials between 3 states:\n\n- specials (like EPS graphics) are displayed;\n\n- specials are displayed along with their bounding box (if\navailable);\n\n- only the bounding box is displayed.\n\nThe states can also be selected directly by using `1v', `2v' and\n`0v' respectively. See also the -postscript option.\n\nCtrl-x [source-what-special()] Display information about the source\nspecial next to the mouse cursor in the statusline. This is the\nsame special that would be found by source-special(), but with-\nout invoking the editor. For debugging purposes.\n\nx [set-expert-mode()] Toggles expert mode, in which the sta-\ntusline, the scrollbars, the menu buttons, the toolbar (Motif\nonly) and the page list are not shown. Typing `1x' toggles the\ndisplay of the statusline at the bottom of the window. Typing\n`2x' toggles the scrollbars (if available). For Xaw, `3x' tog-\ngles the menu buttons and the page list, for Motif, it toggles\nthe page list. In Motif, the additional bindings `4x' toggle the\ntoolbar, and `5x' the menu bar.\nWithout a prefix argument, all of the mentioned GUI elements are\neither switched on (if they had been invisible before) or off.\nToggling the scrollbars may behave erratically with the Xaw wid-\ngets; e.g. the scrollbars may reappear after resizing the win-\ndow, and at certain window sizes one of the scrollbars may fail\nto disappear.\nSee also the option -expertmode (the numbers above correspond to\nthe bits in the argument to -expertmode).\n", "subsections": [] }, "MOUSE ACTIONS IN THE MAIN WINDOW": { "content": "The mouse actions can be customized by setting the X resource mouse-\nTranslations. Since there are three different mouse modes (see the\nsection MODES below), there is a special action mouse-modes which lists\nthe actions for each of the three modes: mouse-modes(\"ACTIONS-FOR-\nMODE1\", \"ACTIONS-FOR-MODE2\", \"ACTIONS-FOR-MODE3\"). If only one argu-\nment is specified, this action is used for all modes. The default\nbindings are as follows:\n\nxdvi.mouseTranslations: \\\nShift:mouse-modes(\"drag(+)\")\\n\\\nShift:mouse-modes(\"drag(|)\")\\n\\\nShift:mouse-modes(\"drag(-)\")\\n\\\nCtrl:mouse-modes(\"source-special()\")\\n\\\n: mouse-modes(\"do-href()magnifier(*2)\", \"text-selection()\", \"ruler()\")\\n\\\n: mouse-modes(\"do-href-newwindow()magnifier(*2)\", \"text-selection()\", \"ruler()\")\\n\\\n: mouse-modes(\"magnifier(*3)\")\\n\\\n: mouse-modes(\"wheel(-0.2)\")\\n\\\n: mouse-modes(\"wheel(0.2)\")\\n\\\n: mouse-modes(\"hwheel(-0.2)\")\\n\\\n: mouse-modes(\"hwheel(0.2)\")\\n\\\n\nAll of these actions are described in more detail below. Note the use\nof quote symbols around the action strings, which are necessary to\ngroup them into one argument. Buttons 4, 5, 6, and 7 refer to wheel\nmovements (wheel up/down/left/right) on wheel mice. Not all mice sup-\nport horizontal scrolling.\n\nThe X Toolkit routines that implement translations do not support event\ntypes of Btn6Down or Btn7Down. Because of this, xdvi implements its\nown parser for translations given in mouseTranslations. This parser is\nmore limited than the parser built in to the X Toolkit. The string\ngiven in mouseTranslations should not begin with ``#replace'', ``#aug-\nment'', or ``#override''. Modifiers of the form @keysym are not sup-\nported, and the event type must be of the form BtnDown or BtnnDown,\nwhere n is a positive integer without leading zeroes. Also, some limi-\ntations apply to the action field.\n\ndo-href()\n\ndo-href-newwindow()\nUsually, if a binding specifies more then one action, all ac-\ntions are executed in a sequence. The hyperlink bindings do-\nhref() and do-href-newwindow() are special in that they are used\nas an alternative to other actions that might follow them if the\nmouse is currently located on a hyperlink. In this case, none\nof the other actions will be executed; otherwise, only the other\nactions are executed.\nThe action do-href() jumps to the link target in the current xd-\nvi window (eventually switching to another page), and do-href-\nnewwindow() opens a new instance of xdvi for the link target.\nIn both cases, the location of the target is indicated by a\nsmall arrow drawn in the same color as a visited link in the\nleft corner of the window.\n\nmagnifier(n x m)\n\nmagnifier(*n)\nThis action will pop up a ``magnifying glass'' which shows the\nunshrunk image of the region around the mouse pointer. The mag-\nnifier disappears when the mouse button is released. Moving the\nmouse cursor while holding the button down will move the magni-\nfier.\nDifferent mouse buttons produce different sized windows, as in-\ndicated by the argument of the magnifier() action. Its argument\nis either a string of the form widthxheight, as in the -mgsn\ncommand-line option, or one of the strings *1 through *5, refer-\nring to the value specified by the corresponding -mgsn option.\n\ndrag(+)\n\ndrag(|)\n\ndrag(-)\nDrags the page with the mouse. This action should have one pa-\nrameter, the character ``|'', ``-'', or ``+'', indicating verti-\ncal dragging only, horizontal dragging only, or dragging in all\ndirections.\n\nsource-special()\nThis action starts a ``reverse search'', opening the editor at\nthe location in the TeX file corresponding to the pointer loca-\ntion in the DVI file. See the section on SOURCE SPECIALS, be-\nlow, for more information on this.\n\nwheel()\nThis action can be used to scroll the image with a wheel mouse,\nwhere it is usually bound to mouse button 4 (wheel up) or 5\n(wheel down). The action takes one parameter, giving the dis-\ntance to scroll the image. If the parameter contains a decimal\npoint, the distance is given in wheel units; otherwise, pixels.\nA negative value scrolls up, a positive value scrolls down.\n\nhwheel()\nThis action can be used to scroll the image horizontally with a\nwheel mouse, where it is usually bound to mouse button 6 (wheel\nleft) or 7 (wheel right). The action takes one parameter, giv-\ning the distance to scroll the image. If the parameter contains\na decimal point, the distance is given in wheel units; other-\nwise, pixels. A negative value scrolls left, a positive value\nscrolls right.

The\nkeystroke Ctrl-g jumps to the next match (like pressing the `Find' but-\nton in the search window).\n\nBy default, the matches are highlighted in inverted color. If the dis-\nplay isn't running in TrueColor, or if the X resource matchHighlightIn-\nverted is set to false or the command-line option -nomatchinverted is\nused, xdvi will instead draw a rectangle in highlight color (see the\n-hl option) around the match.\n\nIf a match crosses a page boundary, only the part on the first page is\nhighlighted. Xdvi will scan up to 2 adjacent pages to match strings\ncrossing page boundaries; but note that header or footer lines, or in-\ntervening float pages will be treated as parts of the scanned text.\nSuch text will usually cause multi-page matching to fail.\n\nThis emphasizes the fact that searching in the formatted text (the DVI\noutput) works differently from searching in the source text: Searching\nin the DVI file makes it easier to skip formatting instructions, and\nmakes it possible to search for e.g. hyphenation and equation numbers;\nbut sometimes the formatting results can also get in the way, e.g. in\nthe case of footnotes. In these cases it's better to search in the TeX\nsource instead. The use of source specials will make switching between\nthe xdvi display and the editor with the TeX source easier; see the\nsection SOURCE SPECIALS below for more information on this.\n\nThe text extracted from the DVI file is in encoded in UTF-8 (you can\nview that text by saving the file in UTF-8 format via the File > Save\nas ... menu item). If xdvi has been compiled with locale, nllangin-\nfo() and iconv support, the search term is converted from the character\nset specified by the current locale into UTF-8. (See the output of lo-\ncale -a for a list of locale settings available on your system). If\nnllanginfo() is not available, but iconv is, you can specify the input\nencoding for iconv via the X resource textEncoding (see the output of\niconv -l for a list of valid encodings). If iconv support is not avail-\nable, only the encodings ISO-8859-1 and UTF-8 are supported (these\nnames are case-insensitive).\n\nIdeographic characters from CJKV fonts are treated specially: All white\nspace (spaces and newlines) before and after such characters is ignored\nin the search string and in the DVI file.\n\nTo match a newline character, use \\n in the search string; to match the\nstring \\n, use \\\\n.\n\nIf the checkbox Regular Expression is activated, the string is treated\nas a regular expression in extended POSIX syntax, with the following\nproperties:\n\n- a? matches a zero or one times.\n\n- a* matches a zero or more times.\n\n- a+ matches a one or more times. Note that * and + are greedy, i.e.\nthey match the longest possible substring.\n\n- The pattern . matches any character except for newline. To also\nmatch a newline, use `(.|\\n)'.\n\n- a{n} matches a exactly n times.\n\n- a{n,m} matches a at least n and no more than m times.\n\n- a|b matches a or b. Brackets can be used for grouping, e.g.:\n(a|b)|c.\n\n- The string matched by the nth group can be referenced by \\n, e.g.\n\\1 refers to the first match.\n\n- The characters ^ and $ match the beginning and the end of a line,\nrespectively.\n\n- [abc] matches any of the letters a, b, c, and [a-z] matches all\ncharacters from a to z.\n\n- Each item in a regular expression can also be one of the following\nPOSIX character classes:\n[[:alnum:]] [[:alpha:]] [[:blank:]] [[:cntrl:]] [[:digit:]]\n[[:graph:]] [[:lower:]] [[:print:]] [[:space:]] [[:upper:]]\n\nThese can be negated by inserting a ^ symbol after the first brack-\net: [^[:alpha:]]\n\nFor more details on POSIX regular expressions, see e.g. the IEEE\nStd 1003.1 standard definition available online from:\n\nhttp://www.opengroup.org/onlinepubs/007904975/basedefs/xbdchap09.html\n\n- As a non-standard extension, the following Perl-like abbreviations\ncan be used instead of the POSIX classes:\n\nSymbol Meaning POSIX Class\n\n\\w an alphanumeric character [[:alnum:]]\n\\W a non-alphanumeric character [^[:alnum:]]\n\\d a digit character [[:digit:]]\n\\D a non-digit character [^[:digit:]]\n\\s a whitespace character [[:space:]]\n\\S a non-whitespace character [^[:space:]]\n\n- The following characters are special symbols; they need to be es-\ncaped with \\ in order to match them literally: ( ) [ ] . * ? + ^ $\n\\.\n\n- Matches of length zero are silently skipped.\n\nThe dialog also provides checkboxes to:\n\n- search backwards;\n\n- match in a case-sensitive manner (the default is to ignore case,\ni.e. a search string Test will match both the strings test and TEST\nin the DVI file);\n\n- ignore line breaks and hyphens: This removes all hyphens at the\nends of lines and the following newline characters, and replaces\nall remaining newline characters by white spaces. So hyphenated\nwords will appear as one word to the search, and a search for two\nwords with a space in between will also match the words if they are\nseparated by a linebreak.\nNote that the hyphen removal may cause unwanted side effects for\ncompound words containing hyphens that are wrapped after the hy-\nphen, and that replacing the newlines affects the interpretation of\nregular expressions as follows: The . pattern will also match new-\nlines, and ^ and $ won't match begin and end of lines any more.\n(Since currently there is no option for turning off the greediness\nof * and +, turning on this option will usually result in matches\nthat are longer than desired.)\n\nThe current checkbox settings are saved in the ~/.xdvirc file.\n", "subsections": [] }, "PRINT DIALOG": { "content": "The print dialog window allows you to print all pages, marked pages\n(click or drag Mouse-2 in the page list to mark them), or a range of\npages.

The XPM file used for the\ntoolbar icons can be specified via the resource toolbarPixmapFile,\nwhich should contain a filename that can be found in one of XFILE-\nSEARCHPATH or XDVIINPUTS (see the section FILE SEARCHING below for more\ninformation on these variables). Xdvi will try to split this pixmap\nhorizontally into n pieces, where each piece is as wide as the pixmap\nis high and is treated as an image for toolbar button n. This means\nthat each icon should be a square, and that the entire pixmap should\nhave width n x h if h is the height of the pixmap.\n\nThe resource toolbarTranslations can be used to map icons/buttons to\nspecific actions. The resource should contain a string separated by\nnewline characters, similar to the resources mainTranslations and menu-\nTranslations. Every line must contain either a spacer definition, or\nan icon definition:\n\nA spacer definition is a string SPACER(n), where n is the number of\npixels inserted as separator to the following button.\n\nAn icon definition is a colon-separated list containing the following\nelements:\n\n- the index of an icon in the pixmap file (starting from zero);\n\n- a long tooltip string, displayed in the status area;\n\n- a short tooltip string, displayed as popup;\n\n- a sequence of actions to be performed when the corresponding tool-\nbar button is pushed.\n\nTo illustrate this, the default value of toolbarTranslations looks as\nfollows:\n\nxdvi.toolbarTranslations: \\\nSPACER(5)\\n\\\n0:Open a new document (Key\\\\: Ctrl-f):\\\nOpen file:select-dvi-file()\\n\\\nSPACER(10)\\n\\\n1:Reread this document (Key\\\\: R):\\\nReread file:reread-dvi-file()\\n\\\nSPACER(10)\\n\\\n2:Go to the first page of this document (Key\\\\: 1g):\\\nGo to first page:goto-page(1)\\n\\\n3:Go to the previous page of this document (Key\\\\: p):\\\nGo to previous page:back-page(1)\\n\\\n4:Go to the next page of this document (Key\\\\: n):\\\nGo to next page:forward-page(1)\\n\\\n5:Go to the last page of this document (Key\\\\: g):\\\nGo to last page:goto-page()\\n\\\nSPACER(10)\\n\\\n6:Enlarge the display (Key\\\\: Ctrl-+):Zoom in:\\\nset-shrink-factor(+)\\n\\\n7:Shrink the display (Key\\\\: Ctrl--):Zoom out:\\\nset-shrink-factor(-)\\n\\\nSPACER(10)\\n\\\n8:Jump back to the previous hyperlink (Key\\\\: B):\\\nBack hyperlink:htex-back()\\n\\\nSPACER(10)\\n\\\n10:Print this document:Print:print()\\n\\\nSPACER(10)\\n\\\n11:Toggle marks for odd pages (Key\\\\: 1m):\\\nToggle odd:toggle-mark(1)\\n\\\n12:Toggle marks for even pages (Key\\\\: 2m):\\\nToggle even:toggle-mark(2)\\n\\\n13:Toggle mark for current page (Key\\\\: 2m):\\\nToggle current:toggle-mark()\\n\\\n14:Unmark all pages (Key\\\\: 0m):\\\nUnmark all:toggle-mark(0)\\n\\\nSPACER(10)\\n\\\n18:Display fonts darker (Key\\\\: Alt-Ctrl-+):\\\nFonts darker:change-density(5)\\n\\\n19:Display fonts lighter (Key\\\\: Alt-Ctrl--):\\\nFonts lighter:change-density(-5)\\n\n\nWhen the mouse remains over a toolbar button for a certain period, a\n`tooltip' window is shown, describing what the button does using the\nshort tooltip string from the above resource.

This will result in overstrike characters\nappearing wrong; it may also result in poor display quality if the num-\nber of available colors is very small.\n\nTypically this problem occurs on displays that allocate eight bits of\nvideo memory per pixel. To see how many bits per pixel your display\nuses, type xwininfo in an xterm window, and then click the mouse on the\nroot window when asked. The ``Depth:'' entry will tell you how many\nbits are allocated per pixel.\n\nDisplays using at least 15 bits per pixel are typically TrueColor visu-\nals, which do not have this problem, since their colormap is permanent-\nly allocated and available to all applications. (The visual class is\nalso displayed by xwininfo.) For more information on visual classes\nsee the documentation for the X Window System.\n\nTo alleviate this problem, therefore, one may (a) run with more bits\nper pixel (this may require adding more video memory or replacing the\nvideo card), (b) shut down other applications that may be using much of\nthe colormap and then restart xdvi, or (c) run xdvi with the -install\noption.\n\nOne application which is often the cause of this problem is Netscape.\nIn this case there are two more alternatives to remedying the situa-\ntion.

It needs to be acti-\nvated via the -allowshell command-line option. NOTE: You should never\nuse this option when viewing documents that you didn't compile your-\nself. The backtick specials are not needed for uncompressing gzipped\nPostScript files, since xdvi can do that on the fly if the filename\nends with .eps.gz or .eps.Z (and if the first bytes of the file indi-\ncate that the file is indeed compressed). This is both safer and more\nflexible than the backtick approach, since the default file searching\nrules will apply to such filenames too.\n", "subsections": [] }, "TYPE 1 FONTS": { "content": "Using FreeType (version 2), xdvi can render PostScript Type 1 fonts\ndirectly, without the route via TeX pixel (pk) fonts. The advantage of\nthis is that only one size of each font needs to be stored on disk.\nUnless the -notype1fonts option is used, xdvi will try to render every\nfont using FreeType. Only as a fallback will it invoke an external pro-\ngram (like mktexpk, which in turn may invoke utilities like ps2pk or\ngsftopk) to generate a pixel font from the Type 1 source. The direct\nrendering of the Computer Modern fonts should work out-of-the box,\nwhereas other Type 1 fonts such as the 35 `standard' PostScript\nfonts resident in printers may need to be made accessible for use with\nxdvi, unless your system administrator or TeX distribution has already\ndone so (which is the case e.g. for current TeX Live systems). For the\n35 PostScript resident fonts, xdvik will search using the Fontmap\nprovided with Ghostscript, if necessary. Also, the xdvik distribution\ncomes with a utility called t1mapper to make these fonts available for\nxdvi; see the manual page for t1mapper(1) for usage details. This pro-\ngram is likely to be dropped in the future, however, since it is proba-\nbly not needed anymore.\n\nSPECIALS (GENERALLY)\nAny of the specials used by xdvi may be preceded by the characters\n``xdvi:''. Doing so does not change the behavior of the special under\nxdvi, but it tells other dvi drivers (such as e.g. dvips) to ignore the\nspecial.\n", "subsections": [] }, "SOURCE SPECIALS": { "content": "Some TeX implementations or macro packages provide the facility to au-\ntomatically include so-called `source specials' into a DVI file. These\ncontain the line number, eventually a column number, and the filename\nof the .tex source. This makes it possible to jump from a .dvi file to\nthe corresponding place in the .tex source and vice versa (also called\n`inverse search' - jumping from the DVI file to the TeX file is also\nknown as `reverse search', and jumping from the TeX file to the DVI\nfile as `forward search').\n\nTo be usable with xdvi, source specials in the dvi file must have one\nof the following formats:\n\nsrc:line[ ]filename\nsrc:line:col[ ]filename\nsrc:line\nsrc:line:col\nsrc::col\n\nIf filename or line are omitted, the most recent values are used. The\nfirst source special on each page must be in one of the first two\nforms, since defaults are not inherited across pages.\n\nYou will need a TeX implementation that provides an appropriate switch\n(e.g. -src) or a macro package (such as srcltx.sty or srctex.sty,\navailable from CTAN:macros/latex/contrib/supported/srcltx/) to insert\nsuch source specials into the DVI file.\n\nFor reverse search, the combination Ctrl-Mouse 1 will make xdvi open an\neditor (the value of the -editor command line option) with the file and\nthe line number of the .tex source. See the description of the -editor\noption for more information and example settings.\n\nFor forward search, xdvi has a -sourceposition option that makes xdvi\njump to the page in the DVI file corresponding to the given line (or\nthe closest line having a source special) of the specified file and\nhighlight the found region. See the description of the -sourceposition\noption for more details.\n\nMore information on setting up various editors for use with source spe-\ncials can be found at:\n\nhttp://xdvi.sourceforge.net/inverse-search.html\n", "subsections": [] }, "PAPERSIZE SPECIALS": { "content": "xdvi accepts specials to set the paper size for the document.

(For security reasons, shell escapes are disabled by default.) This option should be rarely used; in particular it should not be used just to uncompress files: that function is done automatically if the file name ends in .Z, .gz, or .bz2. Shell escapes are always turned off if the -safer option is used. -altfont font (.altFont) Declares a default font to use when the font in the dvi file cannot be found. This is useful, for example, with PostScript fonts. -anchorposition anchor Jump to anchor after opening the DVI file. This is only useful when invoking xdvi from other applications. -background color (.background) Determines the color of the background. Same as -bg. -bg color (.background) Determines the color of the background. -browser browser (.wwwBrowser) Defines the web browser used for handling external URLs. The value of this option or resource has the same syntax as the BROWSER environment variable; see the explanation of that variable in the section `ENVIRONMENT' below for a detailed de- scription. If neither the option nor the X resource wwwBrowser is specified, the environment variables BROWSER and WWWBROWSER (in that order) are used to determine the browser command. If these are not set either, the following default value is used: xdg-open %s:htmlview %s:firefox -remote -remote \"openURL(%s,new- window)\":mozilla -remote \"openURL(%s,new-window)\":netscape -raise -remote \"openURL(%s,new-window)\":xterm -e w3m %s:xterm -e lynx %s:xterm -e wget %s -copy (.copy) Always use the copy operation when writing characters to the display. This option may be necessary for correct operation on a color display, but overstrike characters will be incorrect. If greyscale anti-aliasing is in use, the -copy operation will disable the use of colorplanes and make overstrikes come out in- correctly. See also -thorough. -cr color (.cursorColor) Determines the color of the mouse cursor. The default is the same as the foreground color. -debug bitmask|string[,string ...] (.debugLevel) If nonzero, prints additional information on stan- dard output. The argument can be either a bitmask specified as a decimal number, or comma-separated list of strings. For the bitmask representation, multiple values can be specified by adding the numbers that represent the individual bits; e.g. to debug all file searching and opening commands, use 4032 (= 2048 + 1024 + 512 + 256 + 128 + 64). Use -1 to turn on debugging of everything (this will produce huge output). For the string representation, use the strings listed in the following table, with a comma to separate the values; e.g. to debug all file searching and opening commands, use search,ex- pand,paths,hash,stat,open. (The option `kpathsea' is provided as a shorthand for these.) Note that such a list may need to be quoted to prevent the shell from interpreting commas or spaces in the list. The individual numbers and strings have the following meanings: 1 bitmap Bitmap creation 2 dvi DVI translation 4 pk PK fonts 8 batch Batch mode: Exit after reading the DVI file 16 event Event handling 32 ps PostScript interpreter calls 64 stat Kpathsea stat(2) calls 128 hash Kpathsea hash table lookups 256 open Kpathsea file opening 512 paths Kpathsea path definitions 1024 expand Kpathsea path expansion 2048 search Kpathsea searching 4032 kpathsea All Kpathsea options 4096 htex Hypertex specials 8192 src Source specials 16384 client Client/server mode (see -unique and -sourceposition options) 32768 ft FreeType library messages (Type 1 fonts) 65536 ftverbose Verbose FreeType library messages (currently unused) 131072 gui GUI elements Some of the Kpathsea debugging options are actually provided by Kpathsea; see the Debugging section in the Kpathsea manual for more information on these. -density density (.densityPercent) Determines the density used when shrinking bitmaps for fonts. A higher value produces a lighter font. The default value is 40. If greyscaling is in use, this argument does not apply; use -gamma instead. See also the `S' keystroke. Same as -S. -display host:display Specifies the host and screen to be used for displaying the dvi file. By default this is obtained from the environment variable DISPLAY. -dvipspath path (.dvipsPath) Use path as the dvips program to use when printing. The default for this is dvips. The program or script should read the DVI file from standard input, and write the PostScript file to standard output. -editor editor (.editor) Specifies the editor that will be invoked when the source-special() action is triggered to start a reverse search (by default via Ctrl-Mouse 1). The argument to this option is a format string in which occurrences of ``%f'' are replaced by the file name, occurrences of ``%l'' are replaced by the line number within the file, and optional occurrences of ``%c'' are replaced by the column number within the line. If neither the option nor the X resource .editor is specified, the following environment variables are checked to determine the editor command: XEDITOR, VISUAL, and EDITOR (in this sequence). If the string is found as the value of the VISUAL or EDITOR en- vironment variables, then ``xterm -e '' is prepended to the string; if the editor is specified by other means, then it must be in the form of a shell command to pop up an X window with an editor in it. If none of these variables is set, a warning mes- sage is displayed and the command ``xterm -e vi +%l %f'' is used. If no ``%f'' or ``%l'' occurs in the string, the missing format strings are appended automatically. (This is for compatibility with other programs when using one of the environment vari- ables). A new instance of the editor is started each time this command is used; therefore it is preferable to use an editor that can be invoked in `client' mode to load new files into the same in- stance. Example settings are: emacsclient --no-wait (older Emacsen) gnuclient -q (XEmacs and newer Emacsen) gvim --servername xdvi --remote (VIM v6.0+; the `--servername xdvi' option will cause gvim to run a dedicated instance for the files opened by xdvi.) nc (nedit) Note that those strings need to be enclosed into quotes when us- ing them on the command-line to protect them from the shell; when using them as argument for the .editor resource in an X re- source file, no quotes should be used.

These GUI elements can also be (de)activated separately, by combining the appropriate values in the flag argument. This acts similar to the -debug op- tion: The integer flag is treated as a bitmap where each bit represents one element. If the bit has the value 1, the element is switched on, if it has the value 0, the element is switched off. The meaning of the bits is as follows: 1 statusline 2 scrollbars 4 Motif: pagelist, Xaw: buttons and pagelist 8 toolbar (Motif only) 16 menubar (Motif only) For example, to turn on only the statusline and the scrollbars, use 3 (= 1 + 2). See also the `x' keystroke, where the bits are addressed by their positions, from 1 to 3 (Xaw) or 5 (Motif), respectively. If the statusline is not active, all messages that would normally be printed to the statusline will be printed to stdout, unless the -hush- stdout option is used. -fg color (.foreground) Determines the color of the text (foreground). -findstring string This option triggers a search for string in the DVI file men- tioned on the command-line, similar to forward search (see the description of the sourceposition option): If there is already another instance of xdvi running on the displaying that DVI file, it will cause that instance to perform the search instead. The search starts at the top of the current page of the DVI file. -font font (*font) Sets the font used in menus, buttons etc., as described in the X(7x) man page.

When enabled, horizontal and vertical scrolling is done in smaller increments than would correspond to a single click of a mouse wheel. This is only available for hardware that supports the feature, generally touchpads. It is not available for tradi- tional wheel mice. If suitable hardware is not present or if the X server does not support XInput 2.1 or higher, then the high-resolution scrolling feature is turned off and has no ef- fect. (Note: -noxi2scrolling corresponds to xi2Scrolling:off; +noxi2scrolling, to xi2Scrolling:on.) -offsets dimen (.Offset) Specifies the size of both the horizontal and vertical offsets of the output on the page. By decree of the Stanford TeX Project, the default TeX page origin is always 1 inch over and down from the top-left page corner, even when non-American paper sizes are used. Therefore, the default offsets are 1.0 inch. The argument dimen should be a decimal number optionally followed by any of the two-letter abbreviations for units ac- cepted by TeX (pt, pc, in, bp, cm, mm, dd, cc, or sp). By de- fault, the unit will be cm (centimeters). See also -xoffset and -yoffset. -p pixels (.pixelsPerInch) Defines the size of the fonts to use, in pixels per inch. The default value is 600. This option is provided only for backwards compatibility; the preferred way is to set both the resolution and the Metafont mode via the -mfmode option (which see). -paper papertype (.paper) Specifies the size of the printed page. Note that in most cases it's best to specify the paper size in the TeX input file via the line \\usepackage[dvips]{geometry} which will be recognized by both dvips and xdvi; in that case the use of a `-paper' option should be unnecessary. The paper size may be specified in the form widthxheight option- ally followed by a unit, where width and height are decimal num- bers giving the width and height of the paper, respectively, and the unit is any of the two-letter abbreviations for units ac- cepted by TeX (pt, pc, in, bp, cm, mm, dd, cc, or sp). By de- fault, the unit is cm (centimeters). There are also synonyms which may be used: us (8.5x11in), legal (8.5x14in), foolscap (13.5x17in), as well as the ISO sizes a1-a7, b1-b7, c1-c7. Each of these also has a landscape or `ro- tated' variant: usr (11x8.5in), a1r-a7r, etc. For compatibility with dvips, the formats letter (8.5x11in), ledger (17x11in) and tabloid (11x17in) are also supported (these don't have rotated variants). Any of the above sizes may be preceded by a plus sign (`+'); this causes the paper size given here to override any paper size given in the dvi file. The default paper size is 21 x 29.7 cm (A4 size). -pause (.pause) This option provides a simple implementation of incre- mental (stepwise) display, which can be used for presentations. When this option is used, xdvi will pause the display of the current page whenever it encounters a special special-string (xdvi:pause by default; the string can be customized via -paus- especial, see below), and the cursor will change its shape. The action unpause-or-next() (by default bound to the Space key) will display the next portion of the page up to the following special-string, or until the end of the page is reached. When the option is not used, specials containing special-string will be ignored. -pausespecial special-string (.pauseSpecial) Sets the special string that causes xdvi to pause when the -pause option is active. The default value of special-string is xdvi:pause. -postscript flag (.postscript) If flag = 0, rendering of PostScript specials is disabled; instead, bounding boxes will be displayed (if available). A value of 1 (the default) switches PostScript specials on. With a value of 2, the PostScript specials are displayed along with their bounding boxes; this allows you to visually check the correctness of the bounding boxes. The values can also be toggled at runtime with the `v' keystroke and the corresponding numerical prefix arguments 0, 1 and 2. -ps2pdfpath path (.ps2pdfPath) Use path as a conversion program from PostScript to PDF. The program or script should accept two command-line ar- guments: The PostScript file as first argument, and the PDF out- put file as second argument. -rulecolor color (.ruleColor) Determines the color of the rules used for the mag- nifier (default: foreground color). -q (.noInitFile) Ignore the $HOME/.xdvirc startup file (i.e. don't read it at startup, and don't write it at exit). This forces the defaults defined in $HOME/.Xdefaults to be used. See FILES for more information on $HOME/.xdvirc. -rv (.reverseVideo) Causes the page to be displayed with white char- acters on a black background, instead of vice versa. -S density (.densityPercent) Same as -density (which see). -s shrink (.shrinkFactor) Defines the initial shrink factor. The default value is 8. If shrink is given as 0, then the initial shrink factor is computed so that the page fits within the window (as if the `s' keystroke were given without a number). -safer (.safer) This option turns on all available security options; it is designed for use when xdvi is called by a browser that ob- tains a dvi or TeX file from another site. This option selects +nogssafer and +allowshell. -sidemargin dimen (.sideMargin) Specifies the side margin (see -margins). -sourceposition line[:col][ ]filename This option makes xdvi search in the dvi file for the place cor- responding to the indicated line (and, optionally, column) in the .tex source file, and highlight the place found by drawing a rectangle in the highlight color (see the -hl option) around the corresponding text. In addition, when run with this argument (and the -nofork option is not given, which see), xdvi will al- ways return immediately: if it finds another instance of xdvi already showing dvifile, then it will cause that instance to raise its window and move to the given place in the dvi file; otherwise it will start up its own instance in the background. If several instances of xdvi are displaying the respective dvi file, the instance which was last raised to the foreground will be used. The space before filename is only needed if the filename starts with a digit. When the space is used, the argument needs to be enclosed in quotes to prevent the shell from misinterpreting the space as argument separator. This option requires that dvifile be prepared with source spe- cial information. See the section on SOURCE SPECIALS for de- tails on how to do this. Here is a more detailed description of how the filename in the -sourceposition argument is matched with the filename in the source specials: 1. If neither of the filenames contains a path name component, the filenames are compared ignoring the `.tex' extensions in both filenames. 2. Otherwise, if one of the filenames does contain a path compo- nent (e.g.: ./test.tex, ../test.tex, /my/homedir/tex/test.tex or any combination of these), both filenames are expanded to a full path, with any occurrences of ../ and ./ expanded, and multiple slashes removed. The pathname in the -sourceposition is expanded relative to the current working directory of the xdvi -sourceposition in- vocation, and the pathnames in the source specials are ex- panded relative to the path of the current DVI file being viewed. The path names are then compared ignoring the `.tex' exten- sions in both path names." }, { "flag": "", "long": null, "arg": null, "description": "(.statusline) This option is obsolete; use -expertmode flag in- stead (which see). -text-encoding encoding (.textEncoding) Use encoding as the text encoding of the string in the \"Find\" window.

If the DVI file has been completely written by TeX, it will be reloaded automatically. Fractional values (e.g. `2.5') are possible. The default for this option is 0, i.e. no watching. Since xdvi cannot handle partial DVI files, it tries not to reload the file while it is being rewritten.
