Due to historical reasons, CORE::glob() will also -split its argument on whitespace, treating it as multiple patterns, -whereas bsd_glob() considers them as one pattern. - -=head2 META CHARACTERS - - \ Quote the next metacharacter - [] Character class - {} Multiple pattern - * Match any string of characters - ? Match any single character - ~ User name home directory - -The metanotation C<a{b,c,d}e> is a shorthand for C<abe ace ade>. Left to -right order is preserved, with results of matches being sorted separately -at a low level to preserve this order. As a special case C<{>, C<}>, and -C<{}> are passed undisturbed. - -=head2 POSIX FLAGS - -The POSIX defined flags for bsd_glob() are: - -=over 4 - -=item C<GLOB_ERR> - -Force bsd_glob() to return an error when it encounters a directory it -cannot open or read. Ordinarily bsd_glob() continues to find matches. - -=item C<GLOB_LIMIT> - -Make bsd_glob() return an error (GLOB_NOSPACE) when the pattern expands -to a size bigger than the system constant C<ARG_MAX> (usually found in -limits.h). If your system does not define this constant, bsd_glob() uses -C<sysconf(_SC_ARG_MAX)> or C<_POSIX_ARG_MAX> where available (in that -order). You can inspect these values using the standard C<POSIX> -extension. - -=item C<GLOB_MARK> - -Each pathname that is a directory that matches the pattern has a slash -appended. - -=item C<GLOB_NOCASE> - -By default, file names are assumed to be case sensitive; this flag -makes bsd_glob() treat case differences as not significant. - -=item C<GLOB_NOCHECK> - -If the pattern does not match any pathname, then bsd_glob() returns a list -consisting of only the pattern. If C<GLOB_QUOTE> is set, its effect -is present in the pattern returned. - -=item C<GLOB_NOSORT> - -By default, the pathnames are sorted in ascending ASCII order; this -flag prevents that sorting (speeding up bsd_glob()). - -=back - -The FreeBSD extensions to the POSIX standard are the following flags: - -=over 4 - -=item C<GLOB_BRACE> - -Pre-process the string to expand C<{pat,pat,...}> strings like csh(1). -The pattern '{}' is left unexpanded for historical reasons (and csh(1) -does the same thing to ease typing of find(1) patterns). - -=item C<GLOB_NOMAGIC> - -Same as C<GLOB_NOCHECK> but it only returns the pattern if it does not -contain any of the special characters "*", "?" or "[". C<NOMAGIC> is -provided to simplify implementing the historic csh(1) globbing -behaviour and should probably not be used anywhere else. - -=item C<GLOB_QUOTE> - -Use the backslash ('\') character for quoting: every occurrence of a -backslash followed by a character in the pattern is replaced by that -character, avoiding any special interpretation of the character. -(But see below for exceptions on DOSISH systems). - -=item C<GLOB_TILDE> - -Expand patterns that start with '~' to user name home directories. - -=item C<GLOB_CSH> - -For convenience, C<GLOB_CSH> is a synonym for -C<GLOB_BRACE | GLOB_NOMAGIC | GLOB_QUOTE | GLOB_TILDE | GLOB_ALPHASORT>. - -=back - -The POSIX provided C<GLOB_APPEND>, C<GLOB_DOOFFS>, and the FreeBSD -extensions C<GLOB_ALTDIRFUNC>, and C<GLOB_MAGCHAR> flags have not been -implemented in the Perl version because they involve more complex -interaction with the underlying C structures. - -The following flag has been added in the Perl implementation for -csh compatibility: - -=over 4 - -=item C<GLOB_ALPHASORT> - -If C<GLOB_NOSORT> is not in effect, sort filenames is alphabetical -order (case does not matter) rather than in ASCII order. - -=back - -=head1 DIAGNOSTICS - -bsd_glob() returns a list of matching paths, possibly zero length. If an -error occurred, &File::Glob::GLOB_ERROR will be non-zero and C<$!> will be -set. &File::Glob::GLOB_ERROR is guaranteed to be zero if no error occurred, -or one of the following values otherwise: - -=over 4 - -=item C<GLOB_NOSPACE> - -An attempt to allocate memory failed. - -=item C<GLOB_ABEND> - -The glob was stopped because an error was encountered. - -=back - -In the case where bsd_glob() has found some matching paths, but is -interrupted by an error, it will return a list of filenames B<and> -set &File::Glob::ERROR. - -Note that bsd_glob() deviates from POSIX and FreeBSD glob(3) behaviour -by not considering C<ENOENT> and C<ENOTDIR> as errors - bsd_glob() will -continue processing despite those errors, unless the C<GLOB_ERR> flag is -set. - -Be aware that all filenames returned from File::Glob are tainted. - -=head1 NOTES - -=over 4 - -=item * - -If you want to use multiple patterns, e.g. C<bsd_glob("a* b*")>, you should -probably throw them in a set as in C<bsd_glob("{a*,b*}")>. This is because -the argument to bsd_glob() isn't subjected to parsing by the C shell. -Remember that you can use a backslash to escape things. - -=item * - -On DOSISH systems, backslash is a valid directory separator character. -In this case, use of backslash as a quoting character (via GLOB_QUOTE) -interferes with the use of backslash as a directory separator. The -best (simplest, most portable) solution is to use forward slashes for -directory separators, and backslashes for quoting. However, this does -not match "normal practice" on these systems. As a concession to user -expectation, therefore, backslashes (under GLOB_QUOTE) only quote the -glob metacharacters '[', ']', '{', '}', '-', '~', and backslash itself. -All other backslashes are passed through unchanged. - -=item * - -Win32 users should use the real slash. If you really want to use -backslashes, consider using Sarathy's File::DosGlob, which comes with -the standard Perl distribution. - -=item * - -Mac OS (Classic) users should note a few differences. Since -Mac OS is not Unix, when the glob code encounters a tilde glob (e.g. -~user) and the C<GLOB_TILDE> flag is used, it simply returns that -pattern without doing any expansion. - -Glob on Mac OS is case-insensitive by default (if you don't use any -flags). If you specify any flags at all and still want glob -to be case-insensitive, you must include C<GLOB_NOCASE> in the flags. - -The path separator is ':' (aka colon), not '/' (aka slash). Mac OS users -should be careful about specifying relative pathnames. While a full path -always begins with a volume name, a relative pathname should always -begin with a ':'. If specifying a volume name only, a trailing ':' is -required. - -The specification of pathnames in glob patterns adheres to the usual Mac -OS conventions: The path separator is a colon ':', not a slash '/'. A -full path always begins with a volume name. A relative pathname on Mac -OS must always begin with a ':', except when specifying a file or -directory name in the current working directory, where the leading colon -is optional. If specifying a volume name only, a trailing ':' is -required. Due to these rules, a glob like E<lt>*:E<gt> will find all -mounted volumes, while a glob like E<lt>*E<gt> or E<lt>:*E<gt> will find -all files and directories in the current directory. - -Note that updirs in the glob pattern are resolved before the matching begins, -i.e. a pattern like "*HD:t?p::a*" will be matched as "*HD:a*". Note also, -that a single trailing ':' in the pattern is ignored (unless it's a volume -name pattern like "*HD:"), i.e. a glob like E<lt>:*:E<gt> will find both -directories I<and> files (and not, as one might expect, only directories). -You can, however, use the C<GLOB_MARK> flag to distinguish (without a file -test) directory names from file names. - -If the C<GLOB_MARK> flag is set, all directory paths will have a ':' appended. -Since a directory like 'lib:' is I<not> a valid I<relative> path on Mac OS, -both a leading and a trailing colon will be added, when the directory name in -question doesn't contain any colons (e.g. 'lib' becomes ':lib:'). - -=back - -=head1 SEE ALSO - -L<perlfunc/glob>, glob(3) - -=head1 AUTHOR - -The Perl interface was written by Nathan Torkington E<lt>gnat@frii.comE<gt>, -and is released under the artistic license.
