An expedient CPAN uploader for Raku

Build Status


igo create-layout [--directory=.]
igo create-archive  [--directory=.]
igo upload --user=<user> --password=<password>  [--directory=.]


This provides a simple way to upload Raku modules to CPAN.

I made it because I found that other things either took over the whole workflow, or didn't do enough.

So all this does is create a tarball of the files in the distribution, using the name and version specified in the META6 file and then uploads it to PAUSE with the credentials specified.

The way this works is that the first time it runs it creates an Oyatul layout specification in your distribution's directory as .layout this will contain all of the files found in the directory which don't begin with a '.', now if you're anything like me you may have your working directory littered with test files and backups and so forth so you may want to edit this file before creating the archive, this can be achieved by running

igo create-layout

When you have all the files that you want to release and then edit the .layout as required (it's JSON and quite obvious,) to remove extraneous files (or, if you want to distribute dot files that didn't get added for instance add them.)

If you want to check that you really have all the files you need in the archive that would be uploaded then you can run

igo create-archive

and inspect and test as you see fit.

When you are all happy with what you are going to upload then you just do

igo upload --username=<PAUSE username> --password=<PAUSE password>

Which will create the archive and upload it with the credentials supplied.

If you don't want to continuously type the credentials at the command line you can create the file $HOME/.config/igo/pause.ini with :

user <username>
password <password>

If you are unhappy with having your password in plaintext then CPAN::Uploader::Tiny does support encrypted files, but you can work that our for yourself.

Please feel free to use the Igo module in your own code, but it isn't well documented for the time being.


This uses Archive::LibArchive to make the tarball to upload, so you will need to have libarchive installed, either via your platform's package manager or by some other means. I don't know if it is available for Windows.

Assuming you have a working Rakudo installation you should be able to install this with zef :

# From the source directory

zef install .

# Remote installation

zef install Igo
