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.
