Rust Analyzer in 2018 and 2019
We (Sourcegraph) have also found the “dump all the data from the compiler” approach limiting because it doesn’t work for the live editing use case (as the article says), and then that means you have 2 analyzers: one used with editors and one used for offline tools like Sourcegraph, DXR, etc. That bifurcation means each one gets less community involvement. The ideal IMO is to always target the live editing use case and add caching and optimizations that use language-specific knowledge, so that in both cases you’re querying a live server but it can compute the answers quickly. I haven’t worked with Rust specifically, but it’s interesting to see that they came to a similar conclusion.<p>BTW Sourcegraph is interested in funding this effort and building better Rust support for code browsing and search into our product using <a href="https://docs.sourcegraph.com/extensions" rel="nofollow">https://docs.sourcegraph.com/extensions</a>. I just reached out to the author.
