Run clippy via command only (not on save)

[jbuckmccready]

Feature description

I'd like to be able to have only cargo check on save but still be able to run clippy via flyCheck manually (feeding results into lsp diagnostics).

I saw this: #334 but from what I can tell the way things are working it's all or nothing, with these being the only possibilities:

• enable clippy and run clippy on save
• disable clippy entirely (cannot run manually) with only check on save
• disable on save entirely and then run check or clippy manually via flyCheck

I want check on save, with flyCheck using clippy, e.g., :RustLsp flyCheck run clippy.

Hey 👋

Something like that can't be implemented by this plugin.
You'll have to request it in the rust-analyzer issues, although I don't think it would be implemented.

An way you could solve this would be to disable clippy in the rust-analyzer settings and use something like nvim-lint to run clippy checks on demand.

Thanks for response, awkward situation, was hoping to get the diagnostics fed into the lsp so I can use telescope to jump between them rather than running from command line and having to jump to file+line independent of telescope.

It shouldn't be hard to contribute clippy support to nvim-lint:

• Use an existing linter as a reference.
• Set cmd = "cargo" and args = { "clippy", "--message-format=json" }.
• Adjust the parsing logic.

Both the LSP client and nvim-lint use the samevim.diagnostic API. So this shouldn't be an issue.
