perl.prov
DESCRIPTION
This module provides the following convenience functions:
path2mod
Convert file path to module name, e.g. File/Find.pm -> File::Find.
mod2path
Convert module name to file path, e.g. File::Find -> File/Find.pm.
path2dep
Convert file path to conventional dependency name, e.g.
File/Find.pm -> perl(File/Find.pm). Note that this differs from
RedHat conventional form perl(File::Find).
mod2dep
Convert module name to conventional dependency name, e.g.
File::Find -> perl(File/Find.pm). Note that this differs from
RedHat conventional form perl(File::Find).
verf
Format module version number, e.g. 2.12 -> 2.120. Currently
truncated to 3 digits after decimal point, except for all zeroes,
e.g. 2.000 -> 2.0.
Update. The algorithm has been amended in almost compatible way so
that versions do not lose precision when truncated. Now we allow
one more .ddd series at the end, but .000 is still truncated by
default, e.g. 2.123 -> 2.123, 2.123456 -> 2.123.456.
verf_perl
Format Perl version number, e.g. 5.005_03 -> 1:5.5.30.
sv_version
Extract version number from B::SV object. v-strings converted to
floats according to Perl rules, e.g. 1.2.3 -> 1.002003.
argv
Obtain a list of files passed on the command line. When command
line is empty, obtain a list of files from standard input, one file
per line. Die when file list is empty. Check that each file
exists, or die otherwise. Canonicalize each filename with
"File::Spec::rel2abs()" function (which makes no checks against the
filesystem).
inc Obtain a list of Perl library paths from @INC variable, except for
current directory. The RPM_PERL_LIB_PATH environment variable, if
set, is treated as a list of paths, seprarated by colons; put these
paths in front of the list. Canonicalize each path in the list.
Finally, the RPM_BUILD_ROOT environment variable, if set, is
treated as installation root directory; each element of the list is
then prefixed with canonicalized RPM_BUILD_ROOT path and new values
are put in front of the list.
After all, only existent directories are returned.
explode
Split given filename into its prefix (which is a valid Perl library
path, according to the inc() function above) and basename. Return
empty list if filename does not match any prefix.
