NAME DateTime::Format::Strptime - Parse and format strp and strf time patterns VERSION version 1.79 SYNOPSIS use DateTime::Format::Strptime; my $strp = DateTime::Format::Strptime->new( pattern => '%T', locale => 'en_AU', time_zone => 'Australia/Melbourne', ); my $dt = $strp->parse_datetime('23:16:42'); $strp->format_datetime($dt); # 23:16:42 # Croak when things go wrong: my $strp = DateTime::Format::Strptime->new( pattern => '%T', locale => 'en_AU', time_zone => 'Australia/Melbourne', on_error => 'croak', ); # Do something else when things go wrong: my $strp = DateTime::Format::Strptime->new( pattern => '%T', locale => 'en_AU', time_zone => 'Australia/Melbourne', on_error => \&phone_police, ); DESCRIPTION This module implements most of strptime(3), the POSIX function that is the reverse of strftime(3), for "DateTime". While "strftime" takes a "DateTime" and a pattern and returns a string, "strptime" takes a string and a pattern and returns the "DateTime" object associated. METHODS This class offers the following methods. DateTime::Format::Strptime->new(%args) This methods creates a new object. It accepts the following arguments: * pattern This is the pattern to use for parsing. This is required. * strict This is a boolean which disables or enables strict matching mode. By default, this module turns your pattern into a regex that will match anywhere in a string. So given the pattern "%Y%m%d%H%M%S" it will match a string like 20161214233712. However, this also means that a this pattern will match any string that contains 14 or more numbers! This behavior can be very surprising. If you enable strict mode, then the generated regex is wrapped in boundary checks of the form "/(?:\A|\b)...(?:\b|\z_/)". These checks ensure that the pattern will only match when at the beginning or end of a string, or when it is separated by other text with a word boundary ("\w" versus "\W"). By default, strict mode is off. This is done for backwards compatibility. Future releases may turn it on by default, as it produces less surprising behavior in many cases. Because the default may change in the future, you are strongly encouraged to explicitly set this when constructing all "DateTime::Format::Strptime" objects. * time_zone The default time zone to use for objects returned from parsing. * zone_map Some time zone abbreviations are ambiguous (e.g. PST, EST, EDT). By default, the parser will die when it parses an ambiguous abbreviation. You may specify a "zone_map" parameter as a hashref to map zone abbreviations however you like: zone_map => { PST => '-0800', EST => '-0600' } Note that you can also override non-ambiguous mappings if you want to as well. * locale The locale to use for objects returned from parsing. * on_error This can be one of 'undef' (the string, not an "undef"), 'croak', or a subroutine reference. * 'undef' This is the default behavior. The module will return "undef" on errors. The error can be accessed using the "$object->errmsg" method. This is the ideal behaviour for interactive use where a user might provide an illegal pattern or a date that doesn't match the pattern. * 'croak' The module will croak with an error message on errors. * sub{...} or \&subname When given a code ref, the module will call that sub on errors. The sub receives two parameters: the object and the error message. If your sub does not die, then the formatter will continue on as if "on_error" was 'undef'. $strptime->parse_datetime($string) Given a string in the pattern specified in the constructor, this method will return a new "DateTime" object. If given a string that doesn't match the pattern, the formatter will croak or return undef, depending on the setting of "on_error" in the constructor. $strptime->format_datetime($datetime) Given a "DateTime" object, this methods returns a string formatted in the object's format. This method is synonymous with "DateTime"'s strftime method. $strptime->locale This method returns the locale passed to the object's constructor. $strptime->pattern This method returns the pattern passed to the object's constructor. $strptime->time_zone This method returns the time zone passed to the object's constructor. $strptime->errmsg If the on_error behavior of the object is 'undef', you can retrieve error messages with this method so you can work out why things went wrong. EXPORTS These subs are available as optional exports. strptime( $strptime_pattern, $string ) Given a pattern and a string this function will return a new "DateTime" object. strftime( $strftime_pattern, $datetime ) Given a pattern and a "DateTime" object this function will return a formatted string. STRPTIME PATTERN TOKENS The following tokens are allowed in the pattern string for strptime (parse_datetime): * %% The % character. * %a or %A The weekday name according to the given locale, in abbreviated form or the full name. * %b or %B or %h The month name according to the given locale, in abbreviated form or the full name. * %c The datetime format according to the given locale. Note that this format can change without warning in new versions of DateTime::Locale. You should not use this pattern unless the string you are parsing was generated by using this pattern with DateTime and you are sure that this string was generated with the same version of DateTime::Locale that the parser is using. * %C The century number (0-99). * %d or %e The day of month (01-31). This will parse single digit numbers as well. * %D Equivalent to %m/%d/%y. (This is the American style date, very confusing to non-Americans, especially since %d/%m/%y is widely used in Europe. The ISO 8601 standard pattern is %F.) * %F Equivalent to %Y-%m-%d. (This is the ISO style date) * %g The year corresponding to the ISO week number, but without the century (0-99). * %G The 4-digit year corresponding to the ISO week number. * %H The hour (00-23). This will parse single digit numbers as well. * %I The hour on a 12-hour clock (1-12). * %j The day number in the year (1-366). * %m The month number (01-12). This will parse single digit numbers as well. * %M The minute (00-59). This will parse single digit numbers as well. * %n Arbitrary whitespace. * %N Nanoseconds. For other sub-second values use "%[number]N". * %p or %P The equivalent of AM or PM according to the locale in use. See DateTime::Locale. * %r Equivalent to %I:%M:%S %p. * %R Equivalent to %H:%M. * %s Number of seconds since the Epoch. * %S The second (0-60; 60 may occur for leap seconds. See DateTime::LeapSecond). * %t Arbitrary whitespace. * %T Equivalent to %H:%M:%S. * %U The week number with Sunday the first day of the week (0-53). The first Sunday of January is the first day of week 1. * %u The weekday number (1-7) with Monday = 1. This is the "DateTime" standard. * %w The weekday number (0-6) with Sunday = 0. * %W The week number with Monday the first day of the week (0-53). The first Monday of January is the first day of week 1. * %x The date format according to the given locale. Note that this format can change without warning in new versions of DateTime::Locale. You should not use this pattern unless the string you are parsing was generated by using this pattern with DateTime and you are sure that this string was generated with the same version of DateTime::Locale that the parser is using. * %X The time format according to the given locale. Note that this format can change without warning in new versions of DateTime::Locale. You should not use this pattern unless the string you are parsing was generated by using this pattern with DateTime and you are sure that this string was generated with the same version of DateTime::Locale that the parser is using. * %y The year within century (0-99). When a century is not otherwise specified (with a value for %C), values in the range 69-99 refer to years in the twentieth century (1969-1999); values in the range 00-68 refer to years in the twenty-first century (2000-2068). * %Y A 4-digit year, including century (for example, 1991). * %z An RFC-822/ISO 8601 standard time zone specification. (For example +1100) [See note below] * %Z The timezone name. (For example EST -- which is ambiguous) [See note below] * %O This extended token allows the use of Olson Time Zone names to appear in parsed strings. NOTE: This pattern cannot be passed to "DateTime"'s "strftime()" method, but can be passed to "format_datetime()". AUTHOR EMERITUS This module was created by Rick Measham.
