I’ve been working on something lately that I hope I will publish sometime next month: it’s a set of tools to manage an APT package repository. The idea is that, given an upload queue (you can set it up as an anonymous FTP, or some directory accessible via SSH/SCP, or whatever floats your boat in your setup and team), you’ll have a web interface to approve those packages, a set of integrated autobuilders building the approved packages in whatever combination of architectures and distributions you want, and all that integrated with reprepro to keep your repository updated. I’ll write more about it when I have released something.
The point now is that, while working on it, I needed some module to parse command-line options and “subcommands” (like
svn update, etc.). As it’s written in Perl, I had a look at CPAN to see if I could see anything. The most promising module was App::Rad, but it lacked a couple of things that were very important for me: my idea was “declaring” all the possible commands and options and have the module do all the work for me (generating the help pages and the default
--helpimplementation, generate the
program help subcommandand so on).
App::Raddidn’t have that, and it didn’t seem to me like that was the direction they wanted to go to with the module. But I figured I’d drop the author an e-mail anyway and see if he liked the idea so I could start adding support for all that…
And boy was that a good idea. He replied a couple of days later, and said that they had liked the idea so much that they had implemented it already (that’s why he took a couple of days to reply), and he sent me an example of the new syntax they had introduced and asked if that was what I was thinking. And not only that, but they added me to the list of contributors just for giving the idea! That completely made my day, free software rocks!
