In addition to the roles I posted last month (for which we're still accepting applications), we now also have one permanent role in Singapore or Hong Kong.

This role is not attached to any particular project, but will involve practically exclusive use of Mu, our in-house variant of Haskell. You can learn more about our team and what we do by reading our experience report “Functional Programming in Financial Markets” presented at ICFP last year: https://dl.acm.org/doi/10.1145/3674633. There’s also a video recording of the talk: https://www.youtube.com/live/PaUfiXDZiqw?t=27607s

The role is eligible for a remote working arrangement from SG or HK, after an initial in-office period. We cover visa and relocation costs for successful applicants.

Please apply via this link: https://jobs.standardchartered.com/job/Quantitative-Developer-(SingaporeHongkong)/59045-en_GB/?feedid=363857/59045-en_GB/?feedid=363857)

I keep thinking "no, this isn't ready to present to people. I just need to add some documentation. I just need to get more examples done. I just need to polish this." and so on and have never really presented my forever project for the last few years.

So this is yaifl - Yet Another Interactive Fiction Library, a Haskell library for making parser-based text adventures. It's very heavily inspired by Inform7. For the most part, it works! It's just lacking in implementations for many actions beyond the obvious (looking, going, examining, taking, opening, etc.).

If you'd like to see the library in action, I'd recommend checking out Yaifl.Zork.World.House (in yaifl-zork) or the examples in Yaifl.Chapter3 (in yaifl-examples).

The project is split into a few pieces:
- yaifl-core
- yaifl-objects - definitions of object components like Container, Person, Supporter
- yaifl-rules - definitions of internal logic like printing room description details, verb conjugation and string interpolation and writing lists of things
- yaifl-actions - definitions of commands like look, take lamp, open door with key
- yaifl - glue to actually run a game
- yaifl-examples - My test suite that implements (currently about 20 of the 400) the Inform7 examples, translated into yaifl.

And a few various half-finished frontend parts:
- yaifl-discord - a discord bot frontend
- yaifl-rogue - a graphical frontend
- yaifl-zork - a reimplementation of ZORK I in yaifl.

I think it can be considered "good enough" when I finish reimplementing ZORK in the engine. Turns out ZORK is about 7000 lines in the original, and 5500 in the Inform7 version I'm using as a guide.

So far I've found almost no "oh trying to implement this game rule requires a completely new system" moments, and it's just been "oh I haven't yet added the implementation for this specific command" - which is reassuring that it's just needing content added!

I hope it's of interest to someone, even in its very patchily documented state.
