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