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.

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.
