flycheck-rust vs lsp-flycheck #59

Closed TatriX closed 6 years ago

TatriX commented 6 years ago

I'm trying to understand should I use this project or use lsp-flycheck?

fmdkdd commented 6 years ago

flycheck-rust merely calls cargo rustc. lsp-flycheck goes with lsp-mode and will interact with the Rust Language Server (RLS) using the language server protocol over stdio.

The latter may have faster turn-around, and other benefits (like auto-completion support), but may still be a bit rough around the edges.

If you just want errors/diagnostics in your buffer, use flycheck-rust. If you want a more complete IDE experience, try lsp-mode/lsp-rust and see it if works for you.

I see. I have an issue with both packages: flycheck shows errors, well, rarely. Mostly I can get it work only once after I open the file. After editing and saving the file no errors will be shown.

fmdkdd commented 6 years ago

Are you, perhaps using rust nightly? There is currently a bug (flycheck/flycheck#1381) that prevents errors to be shown with nightly. Rust stable should be fine though, if not, that's another bug!

TatriX commented 6 years ago

Yeah, it's nightly.

fmdkdd commented 6 years ago

The fix for nightly has been merged. Feel free to open a new issue if you encounter another bug in Flycheck :)
