NAME
       tin, rtin - related files


DESCRIPTION
       This man page describes the various (config) files and their formats used by the tin(1) news‐
       reader. All files are expected to have unix style ('\n' aka LF) line endings.


FILES
       $MAILCAPS
       ~/.mailcap
       /etc/mailcap
       /usr/etc/mailcap
       /usr/local/etc/mailcap
       /etc/mail/mailcap

              mailcap(5) files as defined in RFC1524. The mailcap files are read by tin(1) to deter‐
              mine how to display non-text messages at the local site. Any line that starts with "#"
              is  a  comment. Blank lines are ignored. Otherwise, each line defines a single mailcap
              entry for a single content type. Long lines may be continued by  ending  them  with  a
              backslash character, "\".

              Each  individual  mailcap entry consists of a content-type specification, a command to
              execute, and (possibly) a set of optional "flag" values.

              The "type" field is simply any legal content type name. It is the string that will  be
              matched  against  the  ''Content-Type:'' header to decide if this is the mailcap entry
              that matches the current message. Additionally, the type field may specify  a  subtype
              or a wildcard to match all subtypes.

              The "command" field is any UNIX command and is used to specify the interpreter for the
              given type of message. It will be passed to the shell via the system(3) facility.

              Semicolons  and  backslashes  within the command or any flag field must be quoted with
              backslashes. If the field contains "%s", those two characters will be replaced by  the
              name  of  a file that contains the body of the message. If it contains "%t", those two
              characters will be replaced by the content-type field, including the subtype, if  any.
              If  it  contains  "%{"  followed by a parameter name and a closing "}", then all those
              characters will be replaced by the value of the named  parameter,  if  any,  from  the
              ''Content-Type:''  header.  Finally,  if the field contains "\%", those two characters
              will be replaced by a single "%" character.

              Besides the type and command field the following "flags" are defined:

              compose
                     The "compose" field may be used to specify a program that can be used  to  com‐
                     pose  a  new body or body part in the given format. Its intended use is to sup‐
                     port mail composing agents that support the composition of  multiple  types  of
                     mail  using  external composing agents. As with the view-command, the semantics
                     of program execution are operating system dependent. The result of the  compos‐
                     ing  program may be data that is not yet suitable for mail transport — that is,
                     a Content-Transfer-Encoding may need to be applied to the data.

              composetyped
                     The "composetyped" field is similar to the "compose" field, but is to  be  used
                     when  the composing program needs to specify the ''Content-Type:'' header field
                     to be applied to the composed data. The "compose" field is simpler, and is pre‐
                     ferred for use with existing (non-mail-oriented) programs for composing data in
                     a given format. The "composetyped" field is necessary when the Content-Type in‐
                     formation must include auxiliary parameters, and the composition  program  must
                     then  know  enough  about mail formats to produce output that includes the mail
                     type information.

              edit   The "edit" field may be used to specify a program that can be used  to  edit  a
                     body  or  body  part in the given format. In many cases, it may be identical in
                     content to the "compose" field, and shares the operating-system  dependent  se‐
                     mantics for program execution.

              print  The  "print" field may be used to specify a program that can be used to print a
                     message or body part in the given format. As with the view-command, the  seman‐
                     tics of program execution are operating system dependent.

              test   The "test" field may be used to test some external condition (e.g., the machine
                     architecture,  or  the  window  system  in use) to determine whether or not the
                     mailcap line applies. It specifies a program to be run to test some  condition.
                     The  semantics  of  execution and of the value returned by the test program are
                     operating system dependent. If the  test  fails,  a  subsequent  mailcap  entry
                     should  be  sought.  Multiple  test fields are not permitted — since a test can
                     call a program, it can already be arbitrarily complex.

              needsterminal
                     The "needsterminal" field indicates that the view-command must be run on an in‐
                     teractive terminal. This is needed to inform window-oriented user  agents  that
                     an interactive terminal is needed. (The decision is not left exclusively to the
                     view-command because in some circumstances it may not be possible for such pro‐
                     grams  to tell whether or not they are on interactive terminals.) The needster‐
                     minal command should be assumed to apply to the compose and edit commands, too,
                     if they exist. Note that this is NOT a test - it is a requirement for the envi‐
                     ronment in which the program will be executed, and should typically  cause  the
                     creation  of a terminal window when not executed on either a real terminal or a
                     terminal window.

              copiousoutput
                     The "copiousoutput" field indicates that the output from the view-command  will
                     be  an  extended stream of output, and is to be interpreted as advice to the UA
                     (User Agent mail-reading program) that the output should  be  either  paged  or
                     made scroll-able. Note that it is probably a mistake if needsterminal and copi‐
                     ousoutput are both specified.

              description
                     The  "description"  field  simply  provides  a  textual description, optionally
                     quoted, that describes the type of data, to be used optionally by mail  readers
                     that wish to describe the data before offering to display it.

              textualnewlines
                     The  "textualnewlines" field, if set to any non-zero value, indicates that this
                     type of data is line-oriented and that, if  encoded  in  base64,  all  newlines
                     should  be  converted  to canonical form (CRLF) before encoding, and will be in
                     that form after decoding. In general, this field is needed  only  if  there  is
                     line-oriented  data  of  some type other than text/* or non-line- oriented data
                     that is a subtype of text.

              x11-bitmap
                     The "x11-bitmap" field names a file, in X11 bitmap (xbm) format,  which  points
                     to  an appropriate icon to be used to visually denote the presence of this kind
                     of data.

              nametemplate
                     The "nametemplate" field gives a filename format, in which %s will be  replaced
                     by a short unique string to give the name of the temporary file to be passed to
                     the viewing command. This is only expected to be relevant in environments where
                     filename extensions are meaningful, e.g., one could specify that a GIF file be‐
                     ing  passed to a gif viewer should have a name ending in ".gif" by using "name‐
                     template=%s.gif"

              tin(1) currently only respects the "test", "description",  "nametemplate"  and  partly
              the  "needsterminal" flags, all other flags are internally ignored. It also can't han‐
              dle the "%F" and "%n" expansions yet.

              Example:
                     # mailcap file example
                     image/*;\
                        xv -8 -geometry +0 '%s';\
                        description=%{name} %t-Image;\
                        test=test "$DISPLAY" != "";\
                        nametemplate=%s.IMAGE

                     message/rfc822;\
                        ${PAGER:-"more"} '%s';\
                        edit=${EDITOR:-"vi"} '%s';\
                        compose=${EDITOR:-"vi"} '%s';\
                        print=a2ps '%s';\
                        needsterminal

       /etc/news/server

              default NNTP-server to read news from if  not  reading  from  the  local  spool.   '-g
              server', $NNTPSERVER have higher priority (in that order), the default server given at
              compile time has lower priority.

       ${TIN_HOMEDIR:-"$HOME"}/.cancelsecret

              secret  to  be  used for cancel-locks if tin(1) is built with support for it. An empty
              secret file disables the cancel-lock creation in that case. This file should be  read‐
              able only by the user.

       ${TIN_HOMEDIR:-"$HOME"}/.mime.types
       /etc/mime.types
       /etc/tin/mime.types

              mime type / filename extension pairs

       ${TIN_HOMEDIR:-"$HOME"}/.newsauth

              "nntpserver[:port] password [user]" pairs for NNTP servers that require authorization.
              If  the  password  contains a space or a tab it must be enclosed in double quotes (").
              Usernames must not be enclosed in double quotes and thus can't contain spaces or tabs.
              Any line that starts with "#" is a comment.   Blank  lines  are  ignored.   This  file
              should  be  readable  only for the user as it contains the user's unencrypted password
              for reading news!

              nntpserver
                     full qualified domain name of the news server.  Additionally,  a  port  can  be
                     specified by appending :portnumber.

              password
                     user's unencrypted password for reading news.

              user   username  on  the news server if it differs from the local login. This field is
                     optional.

              Example:
                     # sample .newsauth file
                     news.example.org  secret
                     news.example.net  arcane  guest
                     news.example.com  "top secret"  james.bond AT example.com

       ${TIN_HOMEDIR:-"$HOME"}/.newsrc

              "newsgroupflag [article[,article | -article]...]"  lines.

              newsgroup
                     the name of the newsgroup.

              flag   a flag indicating if the group is subscribed ':' or not '!'.

              article
                     range of already read articles from that group;  numbers  separated  by  commas
                     with  sequential  numbers  collapsed  with hyphens. Empty lines and lines which
                     start with "#" are ignored and not written back.

              Example:
                     # sample .newsrc file
                     news.software.b! 1-666,669
                     news.software.nntp: 1-13245,13247,13249

              mailgroups index files

       ${TIN_INDEX_NEWSDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.news${NNTPSERVER:+"-$NNTPSERVER"}/

              newsgroups index files

       ${TIN_INDEX_SAVEDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.save/

              saved newsgroups index files

       ${TIN_HOMEDIR:-"$HOME"}/.tin/active.mail

              active file ("mailgroupname maxnum minnum mailspool" quadruples) of user's  mailgroups
              (requires tin(1) to be built with mh-mail-handling support).

              mailgroupname
                     must  be  the  pathname of the mailbox relative to field #4 with '/' changed to
                     '.'

              maxnum just put a large number here, something higher than the highest message in  the
                     mailbox

              minnum put 0 here

              mailspool
                     path of mail spool directory. This must be the full pathname to the root of the
                     mail folder area.

              Example:
                     Mail.inbox  12345 00000 /home/foo
                     Mail.outbox 23456 00000 /home/foo

              This allows access to the 'inbox' and 'outbox' folders of user foo.  They are accessed
              via /home/foo/Mail/inbox and /home/foo/Mail/outbox

       ${TIN_HOMEDIR:-"$HOME"}/.tin/active.save

              active file of user's saved newsgroups, used by tin -R.

       /etc/tin/attributes
       ${TIN_HOMEDIR:-"$HOME"}/.tin/attributes

              The  group  attributes  files  may  be  used  to  override  some  global settings from
              ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc on a per group basis. Order is  important  as  last
              match  counts; this allows one to refine attributes for narrowed scopes. Note that the
              scope=<grouplist> line has to be specified before the  attributes  are  specified  for
              that  list  and  each attribute can only be set once per scope section. All attributes
              are set to a reasonable default so you only have to specify  the  attribute  that  you
              want  to  change.  All toggle attributes are set by specifying ON/OFF. Otherwise, they
              function exactly as their global  equivalents.  The  following  group  attributes  are
              available:

              scope  This changes the list of groups to which the attributes that follow will be ap‐
                     plied.  See  the section NEWSGROUP LISTS & WILDCARDS in tin(1) for the types of
                     pattern that can be used here.

                     Determines  whether usenet articles are forwarded as attachment or inline. When
                     set to OFF, the forwarded article will be included in the  body  of  the  mail,
                     while  setting  this  variable to ON will cause the article to be attached as a
                     separate MIME part. Enabling mime_forward is particularly useful  for  articles
                     consisting of multiple MIME parts such as PGP/MIME signed messages or being en‐
                     coded  in  a  different character set than your local one. It is also useful if
                     the receiver should be able to operate on the entire forwarded  article  (i.e.,
                     view  or save it without your comments). On the other hand, if you want to for‐
                     ward only some parts of the article or  to  insert  'inline'  annotations,  you
                     might want to disable this option.  Currently mime_forward is forced if the ar‐
                     ticle  to  be attached is a multipart MIME article, this may change in a future
                     version.  Please note that for this option to have effect, the  tinrc  variable
                     interactive_mailer has to be set to 0 (which is the default).

              mime_types_to_save
                     A  comma  separated  list  of MIME major/minor Content-Types that will be saved
                     when using the view/save and save/autosave features.  A single * can be used to
                     wildcard the major and/or minor type and a ! as the first character in an entry
                     will negate it, eg: image/*,!image/bmp,!text/html. Default is */*

              organization
                     This can be used to set the article header field  ''Organization:''.  It  over‐
                     rides  the setting (if any) of organization in /etc/tin/tin.defaults and $ORGA‐
                     NIZATION (or $NEWSORG on Apollo DomainOS). If it points to a  readable  file  a
                     random  line  from  that  file  will be used. Note that some news servers might
                     still overwrite the ''Organization:'' header.

                     assumed  to  be  the name of a file containing the header and its content to be
                     inserted. If the string starts with a ! then what follows is assumed to be  the
                     path  to a program to be executed to generate the header and its content. %G is
                     expanded  to  the  current  news.group.name  and  %P   is   expanded   to   the

              undeclared_charset
                     Assume  (broken)  articles without MIME charset declaration have this charset —
                     default is  US-ASCII.  This  attribute  works  only  on  systems  with  working
                     iconv(3),    others    might    have    to    compile    tin(1)   with   --dis‐
                     able-mime-strict-charset.

              Example:
                     # include extra headers
                     # assume ISO-8859-1 as charset if no charset is declared

       ${TIN_HOMEDIR:-"$HOME"}/.tin/filter

              The filter file is used to assign scores to certain articles. Based on  the  score  an
              article  can  be  filtered  out (hidden) or marked hot. Empty lines or lines beginning
              with a '#' are ignored. Multiple matching-rules in the same scope are all applied  in‐
              dividually and not only when they all hit at the same time (logical OR not AND).

              comment
                     Every  entry  (rule) in the filter file might get a comment. Multiple lines are
                     allowed (but only for comments yet). Every line must start with the  "comment="
                     keyword. Comments must appear first in the rule.  Comment lines placed within a
                     rule  will be moved to the begin of the next rule. This might be changed in the
                     future. Don't use '#' to mark comments as those lines are ignored and your com‐
                     ments will get lost on the next write of the file.

              group  A comma-separated list of newsgroup patterns in wildmat-style to  which  groups
                     the filter rule will be applied. This line is mandatory!

              case   0=case-sensitive, 1=case-insensitive

              score  Score value of the rule; can also be one of the magic words "kill" or "hot".

              subj   Match  against  ''Subject:''. The matching type used (wildmat or regex) depends
                     on the setting of the tinrc variable wildcard.

              from   Match against ''From:''.  tin(1) converts the contents of the ''From:''  header
                     to  an  old style e-mail address, e.g. ''some AT body.example (John Doe)'' instead
                     of ''John Doe <some AT body.example>'', before trying to match the patterns in the
                     filter rule. The matching type used (wildmat or regex) depends on  the  setting
                     of the tinrc variable wildcard.

              msgid  Match  against ''Message-ID:'' and full ''References:''. The matching type used
                     (wildmat or regex) depends on the setting of the tinrc variable wildcard.

              msgid_last
                     Match against ''Message-ID:'' and last ''References:'' entry (direct responses)
                     only. The matching type used (wildmat or regex) depends on the setting  of  the
                     tinrc variable wildcard.

              msgid_only
                     Match  against  ''Message-ID:''.  The matching type used (wildmat or regex) de‐
                     pends on the setting of the tinrc variable wildcard.

              refs_only
                     Match against ''References:''. The matching type used (wildmat  or  regex)  de‐
                     pends on the setting of the tinrc variable wildcard.

              lines  Match against ''Lines:'', <num matches less than, >num matches more than.

              gnksa  Match  against  ''From:''  address parser return codes. <num matches less than,
                     >num matches more than the returned numeric  value.  GNKSA_LOCAL_DOMAIN_LITERAL
                     or  GNKSA_INVALID_DOMAIN are only returned if disable_gnksa_domain_check is set
                     to false. As the built in domain list is outdated  this  should  be  considered
                     carefully.

              xref   Match  against  ''Xref:''  line. Before any matching is done the line is turned
                     into the same format ''Newsgroups:'' has that is it is turned into a comma sep‐
                     arated newsgroup list with all other information (i.e.   the  article  counter)

                     the tinrc variable wildcard.

              path   Match against ''Path:'' line. This may not work on some servers.  The  matching

              Keymap-file,  containing "keyname value [value]" pairs separated by spaces or tabs. If
              the keymap-file named with full specified locale(5) is not found, less  specific  ones
              are  looked  for.  Various parts will be stripped off the name, in the following order
              codeset, normalized codeset, territory and modifier when looking for the  keymap-file.
              Below  is  a list of all rebindable keynames and their defaults. If a keyname is bound
              to NULL it is unassigned.

                     fault is '%E +%N %F'  with  %E=Editor,  %N=Linenumber  and  %F=Filename  (e.g.,
                     /bin/vi  +7  .article).  See  also  $VISUAL  and $EDITOR under "ENVIRONMENT" in
                     tin(1)

              extquote_handling
                     If ON quotes from external sources will be detected. Default is OFF.

              extquote_regex
                     A regular expression that will be applied when reading articles.  All  matching
                     lines are shown in col_extquote. If extquote_regex is blank, then tin(1) uses a
                     built-in default.

              force_screen_redraw
                     Specifies  whether a screen redraw should always be done after certain external
                     commands. Default is OFF.

              getart_limit
                     If getart_limit is > 0 not more than the last getart_limit  articles/group  are
                     fetched  from the server. If getart_limit is < 0 tin(1) will start fetching ar‐
                     ticles from your first unread minus absolute value of getart_limit. Default  is
                     0, which means no limit.

              goto_next_unread
                     Which  keys  tin(1) should accept to jump to the next unread article.  Possible
                     is any combination of PageDown and PageNextUnread.  When PageDown is set tin(1)
                     jumps to the next article at the end of the current one. When PageNextUnread is
                     set tin(1) jumps immediately to the next article when PageNextUnread  ('<TAB>')
                     is pressed. Default is PageNextUnread.

              group_catchup_on_exit
                     If ON catchup group when leaving with the left arrow key. Default is ON.

              group_format
                     The  format  string used for the Group level. Default is "%n %m %R %L  %s  %F".
                     The following substitutions are supported:
                        %D    date
                        %F    from, name and/or address
                        %I    initials
                        %L    line count
                        %M    message-id
                        %R    number of responses in thread
                        %S    score
                        %m    article marks
                        %n    current thread number
                        %s    subject
                        %%    %

              hide_uue
                     If set to 'No' then raw uuencoded data is displayed. If set to 'Yes' then  sec‐
                     tions  of  uuencoded data will be shown with a single tag line showing the size
                     and filename (much the same as a MIME attachment).  If set to 'Hide  all'  then
                     any line that looks like uuencoded data will be folded into a tag line. This is
                     useful  when  uuencoded data is split across more than one article but can also
                     lead to false positives. This setting  can  also  be  toggled  in  the  article
                     viewer.  Default is 'No'.

              inews_prog
                     Path,  name  and options of external inews(1).  If you are reading via NNTP the
                     default value is "--internal" (use built-in NNTP inews), else it is "inews -h".
                     The article is passed to inews_prog on STDIN via '< article'.

              info_in_last_line
                     If ON, show current group description or article subject in the last line  (not
                     in  the pager and global menu) — ToggleInfoLastLine ('i') toggles setting. This
                     facility is useful as the full width of the screen is available to display long
                     subjects. Default is OFF.

              interactive_mailer
                     If greater than 0 your mailreader will be invoked earlier for reply so you  can
                     use  more  of  its  features  (e.g. MIME, pgp, ...). 1 means include headers, 2
                     means don't include headers (old use_mailreader_i=ON option). 0 turns  off  us‐
                     age. This option has to suit mailer_format. Default is 0.

              inverse_okay
                     If ON use inverse video for page headers and URL highlighting.  Default is ON.

              keep_dead_articles
                     If ON keep all failed postings in ${TIN_HOMEDIR:-"$HOME"}/dead.articles besides
                     keeping  the  last  failed posting in ${TIN_HOMEDIR:-"$HOME"}/dead.article. De‐
                     fault is ON.

              kill_level
                     This option controls the processing and display of articles  that  are  killed.
                     There are 3 options, default is 0 (Kill only unread arts).

                        0  Kill  only unread arts is the 'traditional' behavior of tin(1).  Only un‐
                           read articles are killed once only by marking  them  read.  As  filtering
                           only   happens   on   unread   articles   with   kill_level   set  to  0,
                           art_marked_killed and art_marked_read_selected are only shown once.  When
                           you reenter the group the mark will be gone.

                        1  Kill  all  arts  & show with K will process all articles in the group and
                           therefore there is a processing overhead when using this  option.  Killed
                           articles   are   threaded   as  normal  but  they  will  be  marked  with
                           art_marked_killed.

                        2  Kill all arts and never show will process all articles in the  group  and
                           therefore  there  is a processing overhead when using this option. Killed
                           articles simply does not get displayed at all.

              mail_8bit_header
                     Allows 8bit characters unencoded in the header of mail message. Default is OFF.
                     Turning it ON is effective only if mail_mime_encoding  is  also  set  to  8bit.
                     Leaving  it  OFF is safe for most users and compliant to Internet Mail Standard
                     (RFC5322 and RFC2047). Default is OFF.

              mail_address
                     User's mail address (and full name), if not username@host. This  is  used  when
                     creating articles, sending mail and when pgp(1) signing.

              mail_mime_encoding
                     MIME  encoding  of  the  body  in  mail  message,  if  necessary (8bit, base64,
                     quoted-printable, 7bit). Default is quoted-printable.

              mail_quote_format
                     Format of quote line when  replying  (via  mail)  to  an  article  (%A=Address,
                     %D=Date,   %F=Fullname+Address,   %G=Groupname,   %M=Message-ID,   %N=Fullname,
                     %C=Firstname, %I=Initials). Default is "In article %M you wrote:"

              mailbox_format
                     Select one of the following mailbox-formats: MBOXO (default,  except  on  SCO),
                     MBOXRD  or  MMDF  (default on SCO). See mbox(5) and RFC4155 for more details on
                     MBOXO and MBOXRD and mmdf(5) for more details about MMDF.

              maildir
                     The directory where articles/threads are to be saved in  mbox(5)  format.  This
                     feature  is mainly for use with the mutt(1) mail program. It allows the user to
                     save articles/threads/groups simply by giving '=' as the filename to  save  to.
                     Default is ${TIN_HOMEDIR:-"$HOME"}/Mail.

              mailer_format
                     The  format  string  used  to create the mailer command with parameters that is
                     used for mailing articles to other people. Default is '%M  "%T"  <  %F'  (e.g.,
                     /bin/mail  "iain"  < ~/.article). The flexible format allows other mailers with
                     different command line parameters to be used such as
                        sendmail -oem -t < %F
                        mutt -s "%S" -- "%T" < %F
                        mutt -H %F
                        claws-mail --compose "mailto:%T?subject=%S&insert=%F"
                     interactive_mailer must be set adequate. The following substitutions  are  sup‐
                     ported:
                        %F              filename
                        %M              default_mailer
                        %S              subject-field
                        %T              to-filed
                        %U              username
                        %%              %

              mark_saved_read
                     If ON mark articles that are saved as read. Default is ON.

              mark_ignore_tags
                     When  this  is ON, the GroupMarkThdRead ('K'), ThreadMarkArtRead ('K'), MarkTh‐
                     dUnread ('Z') at Group level and MarkArtUnread ('z') at Thread level  functions
                     mark  just the current article or thread, ignoring other tagged, (un)read arti‐
                     cles. When OFF, the same function presents a menu with choices of  the  current
                     thread or article, all tagged, unread articles, or nothing.

              metamail_prog
                     Path, name and options of external metamail(1) program used to view non-textual
                     parts  of articles.  To use the built-in viewer, set to --internal. This is the
                     default value when metamail(1) is not installed. Leave it blank  if  you  don't
                     want any automatic viewing of non-textual attachments. The PageViewAttach ('V')
                     command  can  always  be  used  to  manually  view  any  attachments.  See also
                     ask_for_metamail.

              mm_charset
                     Charset supported locally, which is also used for MIME header (charset  parame‐
                     ter  and  charset  name  in  header  encoding)  in  mail  and news postings. If
                     MIME_STRICT_CHARSET is defined at compile time, text in charset other than  the
                     value  of  this parameter is considered not displayable and represented as '?'.
                     Otherwise, all character sets are regarded as compatible with the  display.  If
                     it's  not  set,  the value of the environment variable $MM_CHARSET is used. US-
                     ASCII or compile-time default is used in case neither of them  is  defined.  If
                     your  system  supports  iconv(3),  this  option  is disabled and you should use
                     mm_network_charset instead.

              mm_network_charset
                     Charset used for posting and MIME headers; replaces mm_charset.  Conversion be‐
                     tween mm_network_charset and local charset (determined via  nl_langinfo(3))  is
                     done via iconv(3), if this function is not available on your system this option
                     is  disabled and you have to use mm_charset instead. mm_network_charset is lim‐
                     ited to one of the following charsets:
                        US-ASCII,       ISO-8859-{1,2,3,4,5,7,9,10,13,14,15,16},       KOI8-{R,U,RU}
                        EUC-{CN,JP,KR,TW}, ISO-2022-{CN,CN-EXT,JP,JP-1,JP-2}, Big5, UTF-8
                     Not  all  values might work on your system, see iconv_open(3) for more details.
                     If it's not set, the value of the environment variable $MM_CHARSET is used. US-
                     ASCII or compile-time default is used in case neither of them is defined.

              mono_markdash
                     Character attribute of words emphasized like _this_. It depends on your  termi‐
                     nal  which  attributes are usable. See also word_h_display_marks and word_high‐
                     light.

              mono_markslash
                     Character attribute of words emphasized like /this/. It depends on your  termi‐
                     nal  which  attributes are usable. See also word_h_display_marks and word_high‐
                     light.

              mono_markstar
                     Character attribute of words emphasized like *this*. It depends on your  termi‐
                     nal  which  attributes are usable. See also word_h_display_marks and word_high‐
                     light.

              mono_markstroke
                     Character attribute of words emphasized like -this-. It depends on your  termi‐
                     nal  which  attributes are usable. See also word_h_display_marks and word_high‐
                     light.

              newnews
                     These are internal timers used by tin(1) to keep track of  new  newsgroups.  Do
                     not change them unless you understand what they are for.

              news_headers_to_display
                     Which news headers you wish to see. If you want to see _all_ the headers, place
                     an  '*' as this value. This is the only way a wildcard can be used.  If you en‐
                     ter 'X-' as the value, you will see  all  headers  beginning  with  'X-'  (like
                     X-Alan  or  X-Pape).  You can list more than one by delimiting with spaces. Not
                     defining anything turns off this option.

              news_headers_to_not_display
                     Same as news_headers_to_display except it denotes the opposite. An  example  of
                     using  both options might be if you thought 'X-' headers were A Good Thing(tm),
                     but thought Alan and Pape were miscreants... well then you would  do  something
                     like this: news_headers_to_display=X- news_headers_to_not_display=X-Alan X-Pape
                     Not defining anything turns off this option.

              news_quote_format
                     Format of quote line when posting/following up an article (%A=Address, %D=Date,
                     %F=Fullname+Address,  %G=Groupname,  %M=Message-ID,  %N=Fullname, %C=Firstname,
                     %I=Initials). Default is "%F wrote:".

              nntp_read_timeout_secs
                     Time in seconds to wait for a response from the server. Default is 120.

              normalization_form
                     The normalization form which should be used to normalize  unicode  input.   The
                     possible values are:

                        0  None: no normalization

                        1  NFKC: Compatibility Decomposition, followed by Canonical Composition

                        2  NFKD: Compatibility Decomposition

                        3  NFC: Canonical Decomposition, followed by Canonical Composition

                        4  NFD: Canonical Decomposition

                        5  NFKC_CF:  Compatibility  Decomposition, followed by Canonical Composition
                           and Case Folding
              Some normalization modes are only available if  they  are  supported  by  the  library
              tin(1) uses to do the normalization. NFC should be used if possible.

              page_mime_format
                     Format  string  tin(1)  uses  for  mime  header at Page level.  Default is "[--
                     %T%S%*n%z%*l%!c%!d%*e --]".

              page_uue_format
                     Format string tin(1) uses for uue  header  at  Page  level.   Default  is  "[--
                     %T%S%*n%I%!d%*e --]".

              pos_first_unread
                     If  ON  put  cursor at first unread article in group otherwise at last article.
                     Default is ON.

              post_8bit_header
                     Allows 8bit characters unencoded in the header of a news article, if  set  this
                     also  disables  the  generation of MIME-headers when they are usually required.
                     Default is OFF. Only enacted if post_mime_encoding is also set to  8bit.  In  a
                     number  of  local  hierarchies  where 8bit characters are used, using unencoded
                     (raw) 8bit characters in header is acceptable and sometimes even recommended so
                     that you need to check the convention adopted in the local  hierarchy  of  your
                     interest to determine what to do with this and post_mime_encoding.

              post_mime_encoding
                     MIME  encoding  of  the  body  in  news  message,  if necessary. (8bit, base64,
                     quoted-printable, 7bit). Default is 8bit, which leads to no  encoding.   base64
                     and quoted-printable are usually undesired on usenet.

              post_process_view
                     If  ON,  then  tin(1)  will  start an appropriate viewer program to display any
                     files that were post processed and uudecoded. The program is  determined  using
                     the mailcap(5) file. Default is ON.

              post_process_type
                     This  specifies  whether to perform post processing on saved articles.  Because
                     the shell archive may contain commands you may not  want  to  be  executed,  be
                     careful when extracting shell archives.  The following values are allowed:

                        0  No (default), no post processing is done.

                        1  Shell archives, unpacking of multi-part shar(1) files only.

                        2  Yes, binary attachments and data will be decoded and saved.

              posted_articles_file
                     Keep  posted articles in given file. If the given filename does not contain any
                     expandable strings it will be prefixed with  ${TIN_HOMEDIR:-"$HOME"}/Mail/.  If
                     no  filename  is  set then postings will not be saved. See the section "MAILING
                     PIPING PRINTING REPOSTING AND SAVING ARTICLES" for more information  about  the
                     various expansion characters. Default is 'posted'.

              print_header
                     If  ON, then the full article header is sent to the printer. Otherwise only the

              prompt_followupto
                     If  ON  show empty ''Followup-To:'' header when editing an article.  Default is

              quote_chars
                     The character used in quoting included  text  to  article  followups  and  mail
                     replies.  The '_' character represents a blank character and is replaced with '
                     ' when read, %I is replaced by author's initials. Default is '>_'.

              quote_style
                     This bit coded integer value controls how articles are to be quoted  when  fol‐
                     lowing  up or replying to them. Any of the following options can be combined by
                     adding all relevant values. Default is 5, which means that quote characters are
                     compressed and empty lines are quoted.

                        1  Compress quotes Compress quote characters together when quoting  multiple
                           times (for example, '> > >' will be turned into '>>>'). This option is on
                           by default.

                        2  Quote  Signatures  This  option  is off by default. Signatures are always

                     path starts with a ! the program the path points to will be executed to  gener‐
                     ate  a  signature.  In  order  to pass the group name to the program, %G can be
                     specified. This will be replaced by the name of the current  newsgroup.  --none

              translit
                     If  ON  append  //TRANSLIT  to  the  first  argument of iconv_open(3) to enable
                     transliteration. This means that when a character cannot be represented in  the
                     target  character  set, it can be approximated through one or several similarly
                     looking characters. On systems where this extension doesn't exist, this  option

                     A regular expression that will be applied when reading articles.  All  matching
                     words  are  shown  in  col_markdash  or  mono_markdash. If underscores_regex is
                     blank, then tin(1) uses a built-in default.

              unlink_article
                     If ON remove ${TIN_HOMEDIR:-"$HOME"}/.article after posting. Default is ON.

              url_handler
                     The program that will be run when launching URLs in the  article  viewer  using
                     PageViewUrl ('U'). The actual URL will be appended.  Default is url_handler.pl.

              url_highlight
                     Enable highlighting URLs in message body. Default is ON.

              use_color
                     If enabled tin(1) uses ANSI-colors. Default is OFF.

              use_keypad

              use_slrnface
                     If enabled slrnface(1) will be used to interpret the  ''X-Face:''  header.  For
                     this  option  to  have  any  effect, tin(1) must be running in an xterm(1x) and
                     slrnface(1) must be in your $PATH. Default is OFF.

              utf8_graphics
                     If ON use UTF-8 characters for indicator ('->'), thread/attachment tree and el‐
                     lipsis ('...'). Default is OFF.

              verbatim_begin_regex
                     A regular expression that tin(1) will use to  find  the  begin  of  a  verbatim
                     block. Default is #v+

              verbatim_end_regex
                     A  regular expression that tin(1) will use to find the end of a verbatim block.

                     If ON verbatim blocks will be detected. Default is ON.

              wildcard
                     Allows you to select how tin(1) matches strings. The default is 0 and uses  the
                     wildmat(3) notation, which is how this has traditionally been handled.  Setting
                     this  to  1 allows you to use perl(1) compatible regular expressions pcre(3) or
                     pcre2(3).  (see also perlre(1) and  pcrepattern(3)  or  pcre2pattern(3)).   You
                     will  probably  want to update your filter file if you use this regularly.  NB:
                     Newsgroup names will always be matched using the wildmat(3) notation.

              word_h_display_marks
                     Should the leading and ending stars, slashes, strokes and dashes also  be  dis‐
                     played, even when they are highlighting marks?

                        0  no

                        1  yes, display mark

                        2  print a space instead

              word_highlight
                     Enable  word  highlighting. See word_h_display_marks for the options available.
                     If use_color is enabled the colors specified  in  col_markdash,  col_markslash,
                     col_markstar and col_markstroke are used for word highlighting else the charac‐
                     ter  attributes  specified  in mono_markdash, mono_markslash, mono_markstar and
                     mono_markstroke are used. Default is ON.

              wrap_column
                     Sets the column at which a displayed article body should be wrapped.   If  this
                     value is equal to 0, it defaults to the current screen width.  If this value is
                     greater  than  your  current screen width the part off-screen is not displayed.
                     Thus setting this option to a large value can be used to disable  wrapping.  If
                     this  value  is  negative  the wrap margin is the current screen width plus the
                     given value (as long as the result is still positive, otherwise  it  will  fall
                     back to the current screen width). Default is 0, wrapping at the current screen
                     width.

              wrap_on_next_unread
                     If  enabled  a search for the next unread article will wrap around all articles
                     to find also previous unread articles. If disabled the search stops at the  end
                     of the thread list. Default is ON.

              xpost_quote_format
                     Format  is  the same as for news_quote_format, this is used when answering to a
                     crossposting to several groups with no ''Followup-To:'' set.

              disable_gnksa_domain_check
                     Allow  unregistered  top  level domains. As the list of valid TLDs is no longer
                     actively maintained the default was changed to ON starting with tin(1)  version
                     2.1.5

              disable_sender
                     Don't  generate  a ''Sender:'' header. This has an effect only if inews_prog is

       ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active}

              This file lists the newsgroups that the local site receives. Each newsgroup should  be
              listed  only  once. Each line specifies one group; within each newsgroup, articles are
              assigned unique names, which are monotonically increasing numbers.

              If an article is posted to newsgroups not mentioned in this file, those newsgroups are
              ignored.  If no valid newsgroups are specified, the article is rejected.

              Each line consists of four space-separated fields "name highmark lowmark flags".

              name   is the name of the newsgroup

              highmark
                     is the highest article number that has been used in that newsgroup

              lowmark
                     is the lowest article number in the group; this number is not guaranteed to  be
                     accurate,  and  should only be taken to be a hint. Note that because of article
                     cancellations, there may be gaps in the numbering sequence. If the lowest arti‐
                     cle number is greater than the highest article number, then there are no  arti‐
                     cles in the newsgroup.

              flags  can be one of those

                     y      local postings are allowed

                     n      no local postings are allowed, only remote ones

                     m      the group is moderated and all postings must be approved

                     j      articles in this group are not kept, but only passed on

                     x      articles cannot be posted to this newsgroup

                     =foo.bar
                            articles are locally filed into the ''foo.bar'' group

              tin(1) only  tries  to read the file if you read directly from the local spool, if you
                     read news via NNTP, tin(1) uses the LIST (RFC3977)  or  LIST  COUNTS  (RFC6048)
                     command instead.

       ${TIN_LIBDIR:-NEWSLIBDIR}/active.times

              This  file  provides a chronological record of when newsgroups are created. It is nor‐
              mally updated by the local news server (e.g.  innd(8)) whenever a new  group  is  cre‐
              ated. Each line consist of three space-separated fields "name time creator".

              name   is the name of the newsgroup

              time   is  the  time  when  the  group was created, expressed as the number of seconds
                     since the Epoch.

              creator
                     is the electronic mail address of the person who created the group.

       ${TIN_LIBDIR:-NEWSLIBDIR}/newsgroups

              This file provides short descriptions of each newsgroup. It is normally updated by the
              local  news  server (e.g.  innd(8)) whenever a new group is created. Each line consist
              of two tab-separated fields "group.name             one-line description".

              group.name
                     is the name of the newsgroup

                     read news via NNTP, tin(1) uses the LIST NEWSGROUPS (RFC3977) command instead.

       ${TIN_LIBDIR:-NEWSLIBDIR}/organization

              This  file  might  hold  a  default  organization  to be used in the ''Organization:''
              header. $ORGANIZATION has a higher priority if set.

       ${TIN_LIBDIR:-NEWSLIBDIR}/overview.fmt

              This file  specifies  the  organization  of  the  news  overview  database  (see  also
              newsoverview(5)).  The order of lines in this file is important; it determines the or‐
              der in which the fields will appear in the database. See also overview.fmt(5).  tin(1)
              only  tries  to  read  the file if you read directly from the local spool, if you read
              news via NNTP, tin(1) uses the LIST OVERVIEW.FMT (RFC3977) command instead.

       ${TIN_LIBDIR:-NEWSLIBDIR}/subscriptions

              This file contains a list of newsgroups — one per line — which the client should  sub‐
              scribe  to  when  the user has no ${TIN_HOMEDIR:-"$HOME"}/.newsrc for the news server.
              tin(1) only tries to read the file if you read directly from the local spool,  if  you
              read news via NNTP, tin(1) uses the LIST SUBSCRIPTIONS (RFC6048) command instead.
