Does rslint already support TypeScript? about rslint HOT 16 CLOSED

Did you build from source? It supports TypeScript in the next version but i havent published 0.3 yet because i am lazy i have a couple more things to do

from rslint.

I installed initially from cargo, but after that error, I tried to install from releases pages too, but apparently there is no difference between installing from cargo or prebuilt binaries from releases page

from rslint.

My system is Linux Mint 20.1 Ulyssa (or just derivative of Ubuntu)

from rslint.

Yeah we publish all crates first to crates.io then add a release commit which builds binaries

from rslint.

I converted my typescript file to javascript and now is working properly

from rslint.

I apologize for not having published a version which could actually lint TS before putting it in the readme. If you'd like to still try it you can git clone then either cargo build a binary or cargo run and feed it a path.

Ok, no problems. I'll wait for next publish to taste how rslint is good and close this issue after that

from rslint.

I built rslint from source after running the git clone and it's working fine!

Still waiting for a release 😅 , sometime soon would be great @RDambrosio016

Oh yeah. Totally forgot about a new release. I will try to do a release ASAP.

Also, if you don't mind me asking - I'm trying to basically use rslint to validate some code, though I want to call it directly through Rust.

So initially, I used:

let result = rslint_parser::parse_text_lossy(read_to_string(&f).unwrap().as_str().trim(), 0);

The above code worked just fine for Javascript files, though it didn't work for TS files.

I then moved the crates locally and imported the raw code, instead of downloading the crate from crates.io because the latest release didn't support TS yet.

The above code still doesn't look like it supports TS. What can I use to only validate syntax and stuff in TS and JS files? Which function should I use (I also want to display errors, and result.errors() gave me just that)?

from rslint.

You can make a typescript Syntax then give it to parse_with_syntax. Other functions assume default syntax which is just js

from rslint.

@RDambrosio016 also was wondering, what does the file_id mean? Until now, I've just filled in 0 as the value, but wanted to understand its purpose

from rslint.

its used for rendering errors, at the start of linting, we build a map of IDs to file data in parallel, each file stores its line indices, line starts, etc. This info is then used for rendering errors, recomputing line info for each file for each error gets slow real quick, especially when you have big files

from rslint.

Right, makes sense

from rslint.

TS support is now in 0.3.0
