Coc.nvim: Support for workspaceFolders

[RobertBuhren]

Hi,
I'm having problems to get nvim.coc with ccls working with out-of-tree kernel modules. Initially I thought it is an ccls issue. The full description of my problem is here: https://github.com/MaskRay/ccls/issues/201

I have a folder structure e.g. like this:

root/
    linux/
    mymodule/
        mymod.c

An example entry for the "mymod.c' of the compile_commands.json looks like this:

    {
        "arguments": [
            "gcc",
            "-c",
            "-Wp,-MD,/home/robert/kernel/ccp_test/.ccp_test.mod.o.d",

        ],
        "directory": "/home/robert/kernel/linux",
        "file": "../ccp_test/ccp_test.mod.c"
    },

As you can see, all paths (e.g. include paths) are relative to the "directory" entry of the json node. However, ccls can't find the headers includes in the module.

The author of ccls suggested that this is an issue of my client (nvim.coc) configuration.

Any suggestions what might be the issue here? And what configuration of nvim.coc might affect this issue?

Thanks in advance,

Robert

[chemzqm]

In your root/ folder create a file .ccls-root and add "rootPatterns": [".ccls-root"], to your ccls language server configuration.

[RobertBuhren]

Thanks. Unfortunately this does not work. The result is the same. Could you elaborate on why this setting is necessary? The compilation data base file should contain all required paths and flags.
It does work with clangd though.

Here's the coc config for clangd I use:

{
  "languageserver": {
    "clangd": {
      "command": "clangd",
      "rootPatterns": ["compile_flags.txt", "compile_commands.json", ".vim/", ".git/", ".hg/"],
      "filetypes": ["c", "cpp", "objc", "objcpp"],
    },
 ```

and for ccls

"ccls": {
  "command": "ccls",
  "args": ["--log-file=/tmp/ccls.log"],
  "rootPatterns": [".ccls-root"],
  "filetypes": ["c", "cpp", "objc", "objcpp"],
  "initializationOptions": {
    "cacheDirectory": "/tmp/ccls"
  }
}

},
```
As ccls does provide more features, I'd like to use ccls.

Thanks again for the quick response.

Regards,

Robert

Hm, I got the problem, coc doesn't have correct workspace folders yet, it only send current one to language server.

I'm working on CocList feature, that would add workspace folder support.

[aravind2612krishna]

Just to chime in, I'm facing the same, if not a similar issue.
The ccls log says it is adding a workspace folder which is one level above my project root. I'm not sure how this can be fixed. The rootUri is correct(I give rootPatterns), but because of the incorrect workspace path, the whole thing doesn't work.

12:51:28 ccls initialize.cc:340 I add workspace folder

[chemzqm]

Vim doesn't have concept of workspace, so we need to build one.

Workspace would have add remove save load actions.

If you want a workaround for that, I have that exact same problem. I think it is because it finds a git-folder in the folder above. If I create an empty folder named .git in the correct path everything works again.

I want it to use my compilation_commands.json as a rootmarker, which i think used to work. But now it seems like the git folder has a higher priority. I first noticed the problem after the
change to use "rootPatterns" instead of g:rooter_patterns, and I haven't been able to configure it to work again.

[chemzqm]

I've changed client to send current workspaceFolder (resolved form coc.preferences.rootPatterns) as only workspaceFolders on language server initialize.

The rootPatterns in server configuration is used for resolve rootPath and rootUri on server initialize.

[aravind2612krishna]

I had given compile_commands.json as a rootpattern and it failed to change the workspace path. In addition, it didn't load the compile_commands.json.
I had to remove the line
"rootPatterns": ["compile_commands.json"],
for it to load the file and I had to create a dummy .git folder as @ripperapid suggested for it to set the correct workspace path. I hope this is useful for debug.

[oblitum]

It's worth noticing that there's missing "compile_commands.json" as rootPattern at the start of this discussion, it's important, and the wiki should be taken as reference. Later on, it was mentioned by those that chimed in.

It would be weird that ".git/" takes priority over "compile_commands.json" if ".git/" comes latter in the rootPatterns list. Personally I can't reproduce that, I just tried a project dir with "compile_commands.json" and coc.nvim + ccls worked fine recognizing it, even when this project is deep in the parent git repo of my dotfiles.

I didn't try the relative path issue.

I'd just like to comment, the wiki is good reference for good defaults for rootPatterns, and you frequently may also avoid a clang database and simply use flags per dir like .ccls, compile_flags.txt, etc. Also, that the compilation database, as mentioned, worked for clangd but not for ccls, seems to point that it could be a LSP server misconfiguration, instead of coc to blame.

[wbthomason]

@oblitum With coc.nvim + ccls configured exactly as given in the wiki, I'm seeing the same exact bug as reported by @aravind2612krishna and @ripperapid, and fixed by the exact same workaround (add a dummy .git in my desired root and remove compile_commands.json from the rootPatterns list.

[oblitum]

@wbthomason I can't reproduce this, I use compile_commands.json without problems..

[oblitum]

@wbthomason did you actually copy the compile_commands.json from the build directory where it's generated to the root one?

[wbthomason]

@oblitum Yup, I tried that, as well as keeping it in build/ with the appropriate initializationOption set for ccls (specifically, "compilationDatabaseDirectory": "build"). Neither works. Running mkdir .git in my desired root (the same directory I'd copied compile_commands.json to) does work.

I have, however, just tried reintroducing compile_commands.json to my configured rootPatterns and found that everything still works (with .git in place). As soon as I delete .git from the root, the problem reappears.

[wbthomason]

I'll also note that my unchanged setup worked previously with LanguageClient-Neovim without any further configuration of ccls, so I don't think the problem is with my workspace configuration?

[oblitum]

Can't reproduce this, I just copied a project to /tmp, removed the ./.git, and now I don't even have any far parent root with a .git dir, it's simply a plain CMake project directory on /tmp/foo, without any git involved, I got there and run CMake and copied the generated database in the build directory to the project folder, and I opened a c++ source in the project folder, and it's simply following the flags from the compilation database for the file, no issues...

[oblitum]

I do my configuration from .vimrc, but I guess that doesn't affect anything, it's similar to the wiki.

[wbthomason]

Indeed, trying your configuration in my .vimrc does not change anything. Interestingly, when I try the same test you did (in my case, making a fresh Meson project in a temp dir), ~I also cannot reproduce the issue. It's only there with my more complex project.~

EDIT: I spoke too soon. By adding a layer of nesting in the directories, I can reproduce the issue.

[oblitum]

I'll also note that my unchanged setup worked previously with LanguageClient-Neovim without any further configuration of ccls, so I don't think the problem is with my workspace configuration?

Not sure how you see that, the LSP clients are completely different, and each is configured in their own way. That one client is configured correctly doesn't imply the other is.

[oblitum]

It's only there with my more complex project.

Well, so I guess that's what needs to be clarified.

[wbthomason]

coc_ccls_bug_example.tar.gz
If you unzip that tarball, you can look at what I used to reproduce the issue with a dead-simple project. There's a .git directory in the top-level (coctest), then the project root itself is in coctest/example/barfoo with a compile_commands.json. Opening example.cc with the minimal coc.nvim configuration given in the README and the ccls + coc.nvim configuration given in the wiki results in ccls being unable to find the file example.hh. When example.cc is opened with LCN and ccls, example.hh is found.

This directory structure mimics my more complex project.

[oblitum]

Indeed I was simply unable to get the include recognized. I've even simplified compile_commands.json to the most basic level, using absolute paths:

[
  {
    "directory": "/tmp/coctest/example/barfoo",
    "command": "c++ -I/tmp/coctest/example/barfoo/foobar/include -std=c++17 -c example.cc",
    "file": "example.cc"
  }
]

Even then, cd /tmp/coctest/example/barfoo/, nvim example.cc and the issue is still there. While still on /tmp/coctest/example/barfoo/, touch .git, nvim example.cc, and the issue is gone.

The above simplified compile_commands.json lies on /tmp/coctest/example/barfoo/.

[oblitum]

I think that makes things a lot simpler to understand, and it's some very basic issue, still no sure whether it's coc or ccls to blame, but compile_commands.json is not being as helpful as .git for looking up include paths somehow.

[oblitum]

Funny, I did touch .git, so it's a file :D

[oblitum]

ping @chemzqm. Given the above resolution, do you still think this is a matter of more complex workspaceFolder support to fix it? It looked like a simpler bug for me.

[siddharth99]

I am facing a similar issue; any help or workaround would be great. My coc-config file is as listed below; the code directory consists of multiple nested git repositories.

{
  "timeout": 1000,
  "hoverTarget": "echo",
  "rootPatterns": [".ccls-root"],
  "languageserver": {
    "ccls": {
      "command": "ccls",
      "args": ["--log-file=/tmp/ccls_coc.log"],
      "trace.server": "verbose",
      "filetypes": ["c", "cpp", "objc", "objcpp"],
      "rootPatterns": [".ccls-root"],
      "initializationOptions": {
        "cacheDirectory": "/tmp/ccls_coc",
        "compilationDatabaseDirectory": "/home/code",
        "index": {"threads": 4},
        "clang": {"resourceDir": "/x/clang60/lib/clang/6.0.1"},
        "completion": {"filterAndSort": true}
      }
    }
  }
}

I created a file /home/code/.ccls-root
If I open a file /home/code/repo1/folder1/main.cpp the workspace directory in ccls log is set as /home/code/repo1 (which contains a .git file but I removed .git from rootPatterns).

I tried setting rootPatterns to compile_commands.json, .ccls-root (touch .ccls-root) but none of them are able to set the workspace-directory in ccls correctly. I am just dealing with 1 large code-base so don't really indend to use multiple workspaces for now.

Just to confirm the problem the async linting is working file but none of the goto definition, implementation type things are working.

LanguageClient-neovim doesn't have support for workspace directories (afaik) and it was able to find the LC root directory correctly probably just using compile_commands.json since I didn't have to specify anything on it. Here, I also need to specify compile_commands.json manually; I would very much like to switch to coc.nvim since it works better than languageclient-neovim which seems to get stuck ever so often for me.

[chemzqm]

  "timeout": 1000,
  "hoverTarget": "echo",
  "rootPatterns": [".ccls-root"],

Those configurations're not supported, install coc-json to get completion and validation support.

[siddharth99]

Thanks! It works after using "coc.preferences.rootPatterns"; sorry for the dumb question; I was earlier using in-line config from my .vimrc so missed the prefixes when I tried coc config.

[oblitum]

I think I'm hitting something related to this issue more explicitly now when trying purescript-language-server. If I open a file with nvim src/Main.purs, I get errors because cwd and root path are resolved badly to <cwd>/src, not <cwd>. If I just open nvim and then :e src/Main.purs, I get no errors. I can avoid the issue if I touch .git. I've used spago to create an empty project and I have 'rootPatterns': ['bower.json', 'psc-package.json', 'spago.dhall'].

  if executable('purescript-language-server')
    let languageservers['purescript'] = {
    \   'command': 'purescript-language-server',
    \   'args': ['--stdio'],
    \   'filetypes': ['purescript'],
    \   'rootPatterns': ['bower.json', 'psc-package.json', 'spago.dhall']
    \ }
  endif

I don't understand why touch .git makes any difference since I don't use it as rootPatterns.

[oblitum]

On nvim src/Main.purs, from :CocInfo I get

Starting with cwd: /home/francisco/samples/purescript/src and using root path: /home/francisco/samples/purescript/src

If I just run nvim and then :e src/Main.purs OR if I touch .git to run nvim src/Main.purs I get

Starting with cwd: /home/francisco/samples/purescript and using root path: /home/francisco/samples/purescript

[oblitum]

I don't understand why touch .git makes any difference since I don't use it as rootPatterns.

Does setting 'rootPatterns' actually extend instead of overriding the default 'rootPatterns' (['.vim/', '.git/', '.hg/', '.projections.json'])? If so, I think docs could make that clear.

[chemzqm]

It's not, please provide verbose output from language server.

rootPath and rootUri is expected, the problem is language server doesn't respect them, but use cwd of process instead.

[oblitum]

Hmm, ok, thanks @chemzqm.

[oblitum]

@chemzqm any explanation why touch .git fix the problem then? I think .git doesn't affect servers, just the client.

[chemzqm]

@chemzqm any explanation why touch .git fix the problem then? I think .git doesn't affect servers, just the client.

It affect workspaceFolders, I think I should pass workspaceFolders same as rootUri until there's real workspaceFolders support.

[chemzqm]

I just disabled workspaceFolders support in language-client, since it's not workspaceFolders should be.

[oblitum]

@chemzqm ok, thanks. Sadly it produced no effect to that purescript server :-/, exactly same behavior (not working opening with nvim src/Main.purs, works with :e src/Main.purs or touch .git).

[chemzqm]

@oblitum verbose output from language server is needed,workspaceFolders should not exists in initialize request.

## Output channel: prettier

[chemzqm]

"Output directory does not exist at 'output'" looks like it needs some additional configuration.

[oblitum]

@chemzqm no no, this happened previously too, I just stripped it before because it's not important. It can't find the output directory because it's at ./output, not ./src/output, and it's taking ./src as root, which it should not, since rootPattern file is at ..

[chemzqm]

It requries workspaceFolders and configuration to work, an extension could help.

fyi: problem with purescript server got fixed in some of the latest commits :+1:
