clunk VS Camlistore

An app for quickly and collaboratively drawing maps for tabletop RPGs.

I run a tabletop RPG for some friends over the Internet using Roll20. As a player in other (in-person) games, there have been times where we've collaboratively made a map as we've gone along rather than the GM providing one, and I wanted to be able to provide a similar experience for my players. Since we found Roll20 didn't really work for this use case, I'm cobbling together an app that tries to make the experience as fluid as possible. It's only really intended for my group when I'll be on hand to explain how it works and I'll be the only one deploying it, so the docs are somewhat sparse, but in case anyone is interested:

I've also been working on a compiler for the most boring programming language in the world: https://github.com/mwilliamson/clunk

I maintain a library with ports to multiple languages (JavaScript, Python, Java). They have very similar structure, which means doing the same thing in pretty much the same way three times each time I make a change.

The idea I wanted to test with my language is: is it possible to extract a common subset that compiles into reasonably idiomatic code for those target languages? The compiled interfaces should be sensible (i.e. use of the code from the target language should be as good as if written in the target language directly), while implementations can be a little less tidy, but ultimately still readable and easily refactorable if the user ever decides to eject from my language and write everything in the target language(s) instead.

I doubt I'll ever use it in anger, and since it's nowhere near ready for use of any kind there aren't really any docs. In the unlikely event someone is interested, the most illuminating thing to look at would be the very beginnings of the reimplementation of the aforementioned library. Since I use snapshot testing with examples, you can see the source code, generated code and result of running the compiled test suite in one file:

There's also Perkeep [1], though it seems like development has slowed down on it in recent years.

You probably just want to pay the cost for hosted. But if you're set on running it yourself, https://perkeep.org/ is great

Perkeep

Not sure how actively it’s being developed but it sounds like perkeep is exactly the idea you’re looking for

So... it just occurred to me that you need to know about https://perkeep.org , I have been following it since the beginning when it was called Camlistore, and notably this talk https://www.youtube.com/watch?v=yxSzQIwXM1k ( from this page: https://perkeep.org/doc/ ).

If you want to live dangerously, this might eventually be useful: https://perkeep.org/
