Trying to follow the your first extension. With javascript, I've also tried this on vscode-minimal-example.

For my extension I wanted an experience similar to the Hashnode AI Editor, so adding commands to the VS Code command palette was not what I was after. What helped me here was the sample extensions directory on GitHub. Their code-actions sample was exactly what I had in mind (and it targets only the markdown files).

Unfortunately I've never used the generator when writing extensions :( However, the extension samples do have several examples (like this one) that have a tsconfig.json and a launch.json that should achieve what you want.

I remember it being difficult to get started. I remember starting by having the autocomplete work with 3 specific words. I think I used this to learn how the lsp works. There are more complicated examples in the root directory https://github.com/microsoft/vscode-extension-samples/tree/main/lsp-sample

VSCode CodeActions Sample

Not true of most compilers.

Can you design compilers that can do this? Sure, i was at IBM when we did visualage, which could do this in other ways, though not optimally.

Is it common? Not a chance.

Your claim that increasingly more modern languages have semantic highlighting in real time is simply false - most cannot real time semantic highlight even a 100k file on every keystroke. There are a very small number which can, and it's mostly by luck - they fall down on larger files because they have no incrementality. Meanwhile, this is trivial with tree-sitter for all languages because of it's optimality. If you want to see it in action - turn on semantic highlighting for vscode and type fast - most of the time you will lose syntax highlighting because things can't keep up. see, e.g., https://github.com/microsoft/vscode-extension-samples/issues...

Again, yes, you could make a compiler for every language which supports a mode that does what tree-sitter does. and people could carefully implement parsers/lexers in each of their favorite compilers and languages that support optimal incremental parsing in them. and then pay the cost of integrating 50 language specific ways of transforming these to work with the editor, basically reinventing what tree-sitter already did right. (As per above, the current semantic token and highlighting support does not resolve this).

You seem to really otherwise be complaining that you believe it does always generate correct parsers. Like I said, that seems totally orthogonal to anything about the speed issue, and if that's your real concern, have at it.

After Googling everywhere for how those little gray bastard are called, here's their name : codeLens and are API of VSCode extensions. An excellent example of how to use them is given here. My first codeLens was to open the file. But then I wanted more! Now my extension can create unit tests file when missing, rename them in the filesystem and code, delete them, generate test template, etc...

Official sample extension (Decorator)

Yes. Darklang was originally in OCaml using js_of_ocaml, and we ported it to F# using Blazor (https://github.com/darklang/dark/tree/main/backend/src/Wasm). It works.

We found that in dotnet 6, the code was much slower, with long startup times and a much bigger download, than in js_of_ocaml. It also had a lot of issues in running in a Webworker, which wasn't the case for js_of_ocaml.

In dotnet 7, the webworker issues are better and AOT is easier, so startup is faster. Download sizes are still bad, and it's still slower than js_of_ocaml.

However, dotnet allows almost any code to run in WASM, which js_of_ocaml had large limitations. This meant a decent chunk of functionality had to be worked around to make separate js vs native targets, which also was a massive pain and took a long time. Dune's virtual targets wasn't ready at the time - I think we were one of the test cases for it.

Why should I use this instead of https://darklang.com/

First it was probably Dark. They made a lot of noise some years ago, but then I never heard of them again (looking at their current website, looks like they moved on to AI now, obviously).

Reminds me of Darklang. Personally, I don't think vendoring cloud services into a language is going to be beneficial. I'm curious how the language deals with vendor updates. Do I have to upgrade the language then? If so, I see a lot conflicts coming from this. Then it comes down to Javascript or HCL, the HCL bit makes me think that the below statement is not as truthy as it is on the surface:

We still don't have all that many users (~100 active), so I'm not sure you'll find an answer here. But we collect that sort of feedback publicly, which might answer your question: https://github.com/darklang/dark/discussions/categories/feed...

I wish I could remember what took me to YCombinator's website on the 10th of October, 2022. That was when I first heard about Wasp and another language called DarkLang. After I learned about Wasp, I was intrigued and curious to know how it works, which led me to join the discord server the next day.

Some languages that try to integrate an HTTP server and a database:

Ur/Web: http://impredicative.com/ur/

Dark (Darklang): https://darklang.com/

There are others in this space I did not assess like Encore, Shuttle, Modal, and Dark. These were not assessed for the sake of time. If you're interested in IfC, I encourage you to take a look at these others.

Oh, finally! I was waiting to build my serverless CRUD webapp in Dark (OCaml + JavaScript and Fsharp?) until they had support for returning negative numbers on a GET request!
