peggy VS purescript

The PEG.js project got taken over by a new maintainer who locked everyone else out, never shipped a release, and then ignored repeated requests to transfer the project back to the community. So the community forked it to a new project - Peggy, which is where ongoing development happens: https://github.com/peggyjs/peggy

NOTE: The original PEG.js project is not maintained anymore, but there is a new fork, Peggy that is maintained and it's backward compatible with PEG.js so it will be easy to switch.

Thanks. Yes, DTL's core textual syntax is described with PEG. I make use of the Peggy (https://peggyjs.org/) PEG processor to build up the AST that is used to actually process DTL.

There are C based PEG processors, which I've looked at once or twice also, but I haven't sat down to try to convert it. Mostly out of a desire to get the existing module to work well. A working module for one language is better than a partially working module for multiple. :P

hmm this article is a bit outdated; peg.js (mentioned in the article) has been discountined for a few years now; recently the project was picked up by another team under the name peggy.js https://github.com/peggyjs/peggy

Naturally I’d recommend using a better language such as ReScript or Elm or PureScript or F#‘s Fable + Elmish, but “React” is the king right now and people perceive TypeScript as “less risky” for jobs/hiring, so here we are.

Unless you want to switch to https://www.purescript.org/.

PureScript[1][2] seems pretty alive these days. From my relatively small, self-contained experiments, it's a lot more flexible and expressive than Elm at the expense of (maybe?) being a bit harder to learn up-front.

*cough* I mean Purescript.

Assuming this is a PS knock, fwiw this went away a good bit ago: https://github.com/purescript/purescript/releases/tag/v0.14.2
