PerlReq::Utils.3pm

NAME

PerlReq::Utils - auxiliary routines for B::PerlReq, perl.req and 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.

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.
