Bolt

Wow a fast scripting language with normal syntax and type checking.. Really hope this can take off and be a valid Lua alternative.

Very cute language .. ``` match x { is table { print(indent_this + "{") for pair in pairs(x) { write(indent + " " + to_string(pair.key) + ": ") pretty_print_internal(pair.value,…

This is really cool but it's not portable to MacOs or aarm64 yet, and that kind of portability unfortunately is what appeals to me about an embeddable scripting language.

Run some examples, and it looks like this "High-performance, real-time optimized, super-fast" language is ``` ~ 10 times slower than luajit ~ 3 times slower than lua 5.4 ```

I used brainfuck interpreter https://github.com/Beariish/bolt/blob/main/examples/bf.bolt vs lua / luajit implementations from https://github.com/kostya/benchmarks Just checked…

I was quite excited by the description and then I noted that Bolt heavily relies on double floating point numbers. I am quite disappointed because this doesn't allow me to use…

Why repeat JavaScript's mistake of having all numbers be floats, with no integer type? I thought that one's well known by now :(

I like 99% of this, and the thing I don't like is in the very first line of the example: > import abs, epsilon from math IMHO it's wrong to put the imported symbols first,…

I don't understand why people still choose the syntax `import xxx from yyy` in the current year. It is a major source of complaining for languages like python or javascript,…

Sounds very good, and I can see many use cases in embedded systems. But that probably requires 32-bit arm support. Is that planned ?

Looks nice! Is there any plans on a language server and formatting tooling? Usually I feel like that's bare minimum before I'd like to try and play around with a language

Looks great, I'm especially a fan of the more C and Python syntax. Lua works, but its syntax has always been bugging me. On the feature side, is there any support for breakpoints…

Congrats! I think this could be quite useful for me. I noticed that `let`-declared variables seem to be mutable. I'd strongly recommend against that. Add a `var` keyword.

Nice language! I am wondering how error handling / exceptions works in bolt? Quickly scanned the programming guide - but wasn't able to find it. Did i miss a section?

I might be missing this, but I'm not seeing anything about how the type system handles (or doesn't) polymorphism - generics, traits, that sort of thing. Is that in there?

Awesome. Is it deterministic like Lua?

I love the concept -- I've often wished that lean languages like Lua had more support for static typing, especially given the potential performance benefits. I also love the…

You may be interested in Luau, which is the gradually-typed dialect of Lua maintained by Roblox. The game Alan Wake 2 also used it for level scripting.

I took away from benchmarks how fast Luau is...

Nice, gives me Pawn vibes (https://www.compuphase.com/pawn/pawn.htm)
