ExtUtils::MakeMaker : how to ignore files and not add them

bliako has asked for the wisdom of the Perl Monks concerning the following question:

Dear Monks,

I am using this very simple Makefile.PL (ExtUtils::MakeMaker):

use ExtUtils::MakeMaker;
WriteMakefile(
        NAME            => 'A::B',
        VERSION_FROM    => 'lib/A/B.pm'
);
[download]

The problem is that it adds a lot of files in the MANIFEST which are either transient (e.g. .lock files - my editor creates a lock file during editing so I end up with A.pm.lock when editing A.pm) or plain rubbish (e.g. *.log or data/). And if these files are later deleted, I need to remake the Makefile.

I have tried adding these file extensions and directories in a ignore.txt file but I still get the same behaviour. I could not see anything relevant in the documentation but I guess is something simple. Does anyone know?

thanks, bliako

ps. EDIT stupidly I omitted the relevant version information: ExtUtils/MakeMaker.pm 7.44 and perl v.5.28.2 in linux fedora 30 with latest updates

EDIT2: see Re: Making ExtUtils::MakeMaker ignore .swp files for a solution

I have tried adding these file extensions and directories in a ignore.txt file They need to go in the `MANIFEST.SKIP` file instead.	[reply] [d/l]

Thanks for the pointer. It must contain regex right? but this `..lock` in a separate line does not have any effect. EDIT: no it DOES WORK, sorry (and in fact should be `.\.lock`).	[reply] [d/l] [select]

What version of ExtUtils::MakeMaker do you have? The line works for me: $ touch .lock $ touch AB.lock $ perl -MExtUtils::MakeMaker -E 'say $ExtUtils::MakeMaker::VERSION' 7.24 $ perl Makefile.PL && make manifest "/home/steveb/perl5/perlbrew/perls/perl-5.26.1/bin/perl" "-MExtUtils:: +Manifest=mkmanifest" -e mkmanifest Added to MANIFEST: .lock Added to MANIFEST: AB.lock # Add entry to MANIFEST.SKIP $ tail -3 MANIFEST.SKIP .base$ main$ .*.lock $ make manifest "/home/steveb/perl5/perlbrew/perls/perl-5.26.1/bin/perl" "-MExtUtils:: +Manifest=mkmanifest" -e mkmanifest Removed from MANIFEST: .lock Removed from MANIFEST: AB.lock [download]	[reply] [d/l]

Yes, each line in MANIFEST.SKIP should be a regex. Full docs are here.	[reply]

I observed another problem: With the simple Makefile.PL I posted and the existence of a lock file, `make` complains. For example: create a lock file for a perl module file I am editing (so, B.pm.lock exists). While the lock file exists, run `perl Makefile.PL` which produces `Makefile`. Exit the editor, the lock file is removed. Finally, do `make`. It complains (for me) that it can not find the lock file as it thinks it depends on it. And true: `grep lock Makefile` finds traces of the lock filename in the Makefile. Any ideas? bw, bliako p.s. I have updated main post to include versions (ExtUtils/MakeMaker.pm 7.44 and perl v.5.28.2 in linux fedora 30 with latest updates)	[reply] [d/l] [select]

Confirmed here with version 7.04 of ExtUtils::MakeMaker. Here's a simple script to reproduce the error. Anything after the `.pm` in the module name will do. `#!/bin/bash mkdir -p lib/A cat > lib/A/B.pm <<EOT package A::B; our \$VERSION = 0.01; 1; EOT cat > Makefile.PL <<EOT use ExtUtils::MakeMaker; WriteMakefile( NAME => 'A::B', VERSION_FROM => 'lib/A/B.pm' ); EOT ext=foo touch lib/A/B.pm$ext perl Makefile.PL rm lib/A/B.pm$ext make` [download] Certainly seems like a bug to me. Update: any file created anywhere within `lib/` appears to trigger it.	[reply] [d/l] [select]

This problem still bothers me and became bigger because now I have a sub-directory containing the files to push to github in my main project dir. Makefile sucks those in, finds duplicate Makefile.PL and chaos ensues. I have found the answer here Re: Making ExtUtils::MakeMaker ignore .swp files, implement `MY::libscan` which decides what file or dir goes in.	[reply] [d/l]
