Toy VS parsec

Over the last couple months or so, I've totally lost my creative spark. I'd been working on a web game and a programming language for 3.5 years and 1 year, respectfully, but both of them reached a point where I don't know what to do next...

Context: I've made my own programming language (Toy), and I'm currently working on a game + engine to go with it. Having some experience with npm, I realize that it might be possible to make something similar to download Toy scripts directly into a mods folder in the game.

Funnily enough, I'm working on a custom scripting language implemented in C. Given how slow Python is, I couldn't implement my lang in it.

People need to promote their langs more - get them out there, you know? Usage is the only way they'll survive.

So I've made my own scripting language called Toy. It was built primarily in a WSL environment, using GCC - the problem is, I also want to support MSVC out of the box. I think it works pretty well as is, with a Visual Studio project provided alongside some makefiles.

And then I wrote the exact same code in JavaScript and C, and compared them. The result was quite good, IMO -

C/C++ is crunchy in a good way, Java is like chewing concrete. JavaScript used to be soft and smooth, but after making my own programming language (which felt silky smooth), JavaScript now feels too soft and sticky.

I'm making a programming language called Toy, which is intended to allow easy modding of video game logic by the players. To this end, each value within Toy, be it a number, a string, a variable name, etc. is stored in a structure called "Toy_Literal".

Don't forget the semicolon.

The goal was partially to make a good jam game, and also to test my custom scripting language Toy. Unfortunately, a combination of a new, crappier computer and the fact that it's an untested lang and engine means that it's really friggin' slow - I'm struggling to get 60fps, even when the simulation rate was adjusted.

Writing Haskell programs that rely on third-party packages is still an issue when it’s a not actively maintained package. They get out of date with the base library (Haskell’s standard library), and you might see yourself in a situation where you need to downgrade to an older version. This is not exclusive to Haskell, but it happens more often than I’d like to assume. However, if you only rely on known well-maintained libraries/frameworks such as Aeson, Squeleto, Yesod, and Parsec, to name a few, it’s unlikely you will face troubles at all, you just need to be more mindful of what you add as a dependency. There’s stackage.org now, a repository that works with Stack, providing a set of packages that are proven to work well together and help us to have reproducible builds in a more manageable way—not the solution for all the cases but it’s good to have it as an option.

The Parsec library for Haskell uses combinators, and there are a few good resources around the internet which explore it, if you know Haskell.

Parse the expression using parsec library ( if you're unfamiliar with it please check out https://hackage.haskell.org/package/parsec) it's a strong library for parer combinators. Once you parse the expression u need to define and sum up the similar terms. Check this example out - https://fpunfold.com/2020/05/18/making-a-calculator-in-haskell-with-parsec.html

Konbini is a functional parser combinator library inspired by Haskell parsing libraries like Parsec. It's (hopefully) fairly easy to use, and is about as performant as the better-parse library. In fact, it's quite similar to better-parse in many aspects. The main difference is in how parsers are composed. Where better-parse prefers operators and infix functions, Konbini instead uses plain functions.

Hi everyone, I'm learning F# and currently trying to do a Parsec-like CE, just to get comfortable with computation expressions.

good libraries for parsing: parsec, attoparsec etc.

Thank you! When I read the title I only knew about https://hackage.haskell.org/package/parsec, and for a moment I was very confused…

The more "idiomatic" way would be to use a parser library, e.g. parsec, attoparsec, or megaparsec. But even then I think it would be a lot easier to maintain if you could preserve the angle brackets <> in the input.
