Considering using TXR as a dependency. What alternatives exist?

[gentle haven]

i'm thinking about winding support for TXR into a library. TXR is really good but i'm wondering what other simple runtime evaluation systems exist for GameMaker that i could support

[gentle haven]

(for those unaware, TXR can be found here https://github.com/YAL-GameMaker/tiny-expression-runtime)

I don’t think I can think of too many from the top of my head, besides the obvious. (Catspeak, that one JSON-based runtime variant that was in Cookbook Jam… can’t remember it)

Or writing your own 🤔

honestly really depends on your use case, there is a bunch of alternatives which all favor differing things. like gmlc is unreleased as its waiting on wittle widgets to have a working code editor so i can release both at once. but that, and as tab said catspeak, are both more feature complete use cases. but if you're just trying to parse numbers and strings, then txr is probably best

i also know of someone who has added function support to txr, so you can define functions inside it

[gentle haven]

now that i'm thinking about it a bit more i don't think i need something as featureful as TXR even

probably better off writing my own thing

[viscid cypress]

something just to run oneline commands?

or arguments?

summons crafting interpreters

[gentle haven]

i've got an expression parser lying around somewhere

[viscid cypress]

i mean you have one in your file parsing library no?

[gentle haven]

yeah but that one's crap

[stable kettle]

Do you need to only evaluate expressions, or also statements?

[gentle haven]

both

[stable kettle]

Yeah it gets more complicated then. Like Tab said, Crafting Interpeters is a great source.

[gentle haven]

thanks but that's not the question

i know how to write a parser etc. but it would be nice to use someone else's

[stable kettle]

Yeah, I don't know whether there are actually other ones freely available (outside what has already been mentioned)

[viscid cypress]

i'll send you access to gmlc, its pretty feature complete feel free to rip anything out of the parser and it should still work pretty seemlessly

no need for credits

[gentle haven]

i would like to take a look if nothing else

[viscid cypress]

was designed to be added to or removed from extremely easily

[gentle haven]

oh yeah! i made a parser for that animation language i wrote

now i remember

[viscid cypress]

it's also got env support just as catspeak does, but if you need something light weight it doesnt need to be in there

but you can check your email i just sent you an invite on github

just dont look at the macros in gen 5

[gentle haven]

mmok thank you very much

i'll snoot around
