ylib - Add paths to @INC from a config file
# in .mylib file /home/david/some/library/path # from the command line $ perl -Mylib -E 'say for @INC' /home/david/some/library/path ...
ylib module adds paths to
@INC from a configuration file named
.mylib in which each line represents a library path. The
.mylib file can be either in the current directory and/or in the user's home directory. It is equivalent to calling
'use lib' on each path.
ylib will issue a warning if a path in
.mylib can't be found.
Occasionally, it's useful to customize
@INC on a per-directory basis without changing the global
PERL5LIB environment variable. For example, when developing or testing code that requires uninstalled code in an adjacent directory, one could create a
.mylib file that adds the necessary path.
For example, consider this directory tree with two Perl distributions, Foo-Bar and Baz-Bam:
~/projects/ Foo-Bar/ Baz-Bam/
The code in Foo-Bar depends on code in Baz-Bam. So in Foo-Bar, create a
.mylib file with the appropriate path:
$ cd Foo-Bar $ echo '../Baz-Bam/lib' > .mylib $ perl -Mylib Build.PL $ Build && Build test
That's easier and shorter than using
PERL5LIB on the command line, and it scales better as the number of libraries increases.
In the example above, the
Build script preserve
@INC including the effect of
-Mylib when it was created. This is not the case with
prove, in which case,
PERL5OPT might be an alternative approach for using
$ export PERL5OPT=-Mylib $ prove
