I made a similar tool in Perl. It eval's a Perl command passed as string, on each line of stdin. In the middle I can go wild with regexes and hash/dictionaries and whatnot. It's one of my most used tools.

Instead of writing scripts for each little task, I just write one-liners. When they become more than 2 lines long it becomes unwieldy and I switch it to a regular script.

I grew up data munging with awk/sed/tail/head manipulations, avoiding Perl 5 (not out of any antipathy, but I just worked off of what my fathers bookshelf had and there was no Camel book on there). Back in the 90s we'd publicly post our dotfiles to our Apache 1.3 servers amongst peers, but (perhaps this was just a component of the IRC community I was a part of) we didn't share much of scripts-sets we built up overtime. The furthest we'd go is "I want to do foo", someone with more knowledge than you would give you a series of invocation parameters and over time you'd osmotically acquire enough knowledge to be the one dispensing knowledge.

From what I hear, Perl 5 is prime for the problem set you defined, but I've never seen any aggregated resource of people's Perl5 munging scripts. Do us all a favor and post a Github Gist of that tool (along with common invocations of you going wild with regexes and hashmaps). If you're feeling overly generous, post the source of the commonly used regular scripts as well.
