tree-sitter is a phenomenal project i’m doing a git-related project myself and use it to generate symbols for source code if you’re into it too, i recommend also checking out…

Different poster, but I have an opinion. I think that if you're going to do React/Redux, your life would be easier in Elm. I'm a full time Clojure/Clojurescript dev and from my perspective, the main thing Elm is lacking is Protocols (in Clojure/Swift, Traits in Rust). I know Evan has been pushing back on it because it adds complexity to learning the language and you can get by without them, but I miss them. I could quibble about other things but there's nothing I strongly dislike. From an adoption perspective, I think a focus on tooling would help a lot. There was a talk at elm-conf where a refactoring suite was written as a chat bot. Ditching the chat bot part and building a language server [1] would make it much easier to pitch the language.

nsition into web dev, the main weakness of Elm is that the community is small so you basically have to build your components yourself. This tends to be challenging for experienced programmers coming from other languages because CSS has no abstractive power at all and the traditional layout techniques are incredibly unintuitive. You'll probably have the most success using flexbox everywhere. The community is friendly and I think Evan does a pretty good job leading it. I've pushed a number of younger developers at js meetups to pick it up and they've reported back with positive impressions. Of the compile to js langauges I know, I'd pick Elm as the most likely to succeed. Overall, I like Elm and am happy with it's progress. I don't think it's ready for unqualified adoption, as you'll be doing a lot of library building you wouldn't need in more mature ecosystems and I'm not completely confident it's on the path to great success. I wouldn't push the language in a workplace at this point. By comparison, I would push Rust. You're in largely the same position in both languages in terms of writing libraries but I think Rust has hit critical mass.

For anyone interested in similar tools, Microsoft recently published a protocol[1] for this type of service, and an implementation[2] of it for VSCode+NodeJS. Swift also has a library[3] called SourceKit which does the same thing for Swift – it can run as an out-of-process daemon, and people have written integrations for Atom, Emacs, etc. to get autocomplete, syntax highlighting, def links, etc. [1]https://github.com/Microsoft/language-server-protocol [2]https://github.com/Microsoft/vscode-languageserver-node [3]https://github.com/apple/swift/tree/master/tools/SourceKit

This appears to be based on the stellar open-source code-editor used by VSCode. Looking at the network traffic, it looks like you are also using the language server protocol [1] to provide context-aware code intelligence. As far as I know this is the only use of the language server protocol in a web browser. Have you documented anywhere how you made this work? [1] https://github.com/Microsoft/language-server-protocol

Visual Studio Code uses OmniSharp as middleware for the C# extension for instance to check code, find usages, and lookup types. The "rename symbol" works fine so far. I guess, but am not sure, they use the language server protocol [1] to communicate with OmniSharp. A few months ago I stumbled upon a Java language server [2] which utilizes Eclipse JDT. Maybe if the Java language server supports refactoring and Vim support the language server protocol, we could have refactoring of Java code in Vim on par with Eclipse.

RE: Other languages this distinction is what you're looking for : https://github.com/Microsoft/language-server-protocol Completely separating the tool layer from the language layer. Red Hat, Eclipse, etc have already implemented tons of languages like https://github.com/Microsoft/language-server-protocol/wiki/P... Haxe, Java, C#, C++ (! probably the most impressive of the list). If you conform to the API you can leverage all of those pre-existing backends.
