Dear Monks,

After 25+ years of submitting perl modules to the CPAN I feel the need to ask the following question.

I have a module Foo version 1.10. It is packaged for CPAN with Makefile.PL and tests as Foo-1.10.tar.gz.

One of the tests fails under specific circumstances so I fix the test. The module does not need changing.

How can I update the kit version (to e.g. 1.10.1) without having to change the module version?

I have a perl_Tk script which has recently started aborting with the following message.

Can't locate loadable object for module Tk::Canvas in @INC (@INC conta

I am using Tk version 804.036001, Strawberry perl 5.38 under windows 7.

Strawberry perl 5.38 is the only perl on my computer. Several months ago I uninstalled a previous version of perl and installed 5.38, then installed Tk with the command cpan Tk. My existing script worked immediately and continued to until some time last week. I am certain that the script has not changed. I am not aware of any changes to perl, Tk, or any of its components, in fact, I have verified that the modules Tk.pm, Tk/widget.pm, and Tk/canvas.pm are all up to date and stored in C:/Strawberry/perl/site/lib. Another Tk script (which does not use canvas) still works.

Does "loadable object" refer to anything other than Tk/canvas.pm? I would appreciate any suggestion on finding and fixing the problem. Of course, I will post any additional material which may be helpful.

Recently I got myself a new phone. And, as one does, I installed Termux on it, to have a unix-ish environment for when I need it.

Then, of course, I went to configure Perl and install some modules I'd like there. As this was not my first time doing so, I thought about listing all the modules I want in a cpanfile and then using App::cpanminus to install these, making the process far more reproducible.

But that required some non-Perl prerequisites, like the C compiler, make and perl itself. And of course, also bootstrapping App::cpanminus.

Then I thought a bit on how to combine this setup into a single file. This is what I came up with. It's a cpanfile that doubles as shell script.

#!/bin/bash

# This will install cpanminus and then the Perl modules
# as listed at the end of this script. To run use
# the following commands:
#
# chmod ugo+x ./cpanfile && ./cpanfile
#

eval '
pkg install git perl make clang

if ! cpanm --help 2>&1 >/dev/null ; then
    curl -L https://cpanmin.us | perl - App::cpanminus
fi

DIR=$(dirname "$0")
cpanm --installdeps --notest --cpanfile "$DIR"

exit
'
if 0;

requires 'Mojolicious';
requires 'DBIx::Spreadsheet';
#requires 'App::sqldisplay'; # to be released on CPAN
requires 'DBIx::RunSQL';

Why not the other way around? Because I could not find a way to make cpanm take a file with a different name than cpanfile :)

The cpanfile is also available on Github, if you want to copy it.
