`Could not find Cargo.toml in someday or any parent directory` about coc-rls HOT 9 CLOSED

coc-rls has problem with reading the true WORKINGDIR.

It doesn't use cwd, it resolve Cargo.toml from current file.

I can't reproduce the problem. Consider upload full output by use "tsserver.trace.server": "verbose", in configuration: "tsserver.trace.server": "verbose",

from coc-rls.

Sorry, I followed your step, but cannot get log as a result of "tsserver.xxx command not found".
But I tried to config rls in coc-settings.json as following:

        "rls": {
            "command": "rustup",
            "args": ["run", "nightly", "rls"],
            "filetypes": ["rust"],
            "settings": {},
            "enable": true,
            "trace.server": "verbose"
        }

The problem was reproduced, and I got the log here:

Do you have Cargo.toml file in directory file:///Users/ionizing/Documents/tests/rusttest/CLRS ?
Maybe your cargo is just too old, and it can't generate the file for you, try upgrade.

from coc-rls.

No. Cargo.toml exists in file:///Users/ionizing/Documents/tests/rusttest/CLRS/coctest, and the rust project root directory is file:///Users/ionizing/Documents/tests/rusttest/CLRS/coctest. When I delete the .git/ in CLRS, both coc-rls and rls works well.

I've fixed this issue in coc-rls, to fix the problem with configuration, you need to add "rootPatterns": ["Cargo.toml"], to rls section.

from coc-rls.

I found a workaround: cd into the root dir of project, open src files via NERDTree and Cargo.toml can be found correctly.

from coc-rls.

I ran into this today... This only happens when you have a git project with multiple rust crates inside, because the default rootPatterns look for the .git directory. Which makes it work without config by chance on "normal" rust crates, because they likely happen to have a .git dir at the same root as the Cargo.toml.

to make this work for sub-crates I opened the config of coc in vim with command :CocConfig and pasted this:

{
	"languageserver": {
		"rls": {
			"command": "rustup",
			"args": ["run", "nightly", "rls"],
			"filetypes": ["rust"],
			"rootPatterns": ["Cargo.toml"]
		}
	}
}

this seems to be the minimal config to make it work. I don't fully understand how the coc-rls plugs into coc, but I'd vote for injecting the "Cargo.toml" into rootPatterns by default when the coc-rls is loaded. This way it actually looks for the cargo.toml in every case, and no custom config file writing is necessary (just having languageserver -> rls -> rootPatterns is not enough, all of the above is needed, probably causing other side-effects?)

thanks, now using autocmd FileType rust let b:coc_root_patterns = ['Cargo.toml', '.git'] in .vimrc
