Do I miss a binary ? I am not familiar with the nodejs ecosystem, can it be due to a version mismatch ?

fannheyward commented 5 years ago

I need some info to check:

  1. Does your texlab binary works ok? You can check it with /home/teto/.config/coc/extensions/coc-texlab-data/texlab -h, texlab version and help info will be printed if success.
  2. After open a tex file, :CocInfo please

so it's kind of weird because the file can be opened via vim/file but if I try to start the

tab completion completes the filename as well so the file is present seems like I am hitting: https://askubuntu.com/questions/133389/no-such-file-or-directory-but-the-file-exists

Looks like the texlab server file is broken. Try latex.UpdateLanguageServer to download new release, or download from https://github.com/latex-lsp/texlab/releases and put into ~/.config/coc/extensions/coc-texlab-data/texlab

teto commented 5 years ago

How can i run the command in ex mode ? Didn t find out

fannheyward commented 5 years ago

You can use :CocCommand latex.UpdateLanguageServer in ex mode.

Hi I run that command. Coc returns coc.nvim] Update TexLab Server success, yet I still have :

@teto texlab is now packaged in NixOS, see https://github.com/NixOS/nixpkgs/pull/73087 . Hence it shouldn't be a problem running it if installed with nix-env. However, From some reason coc-texlab still doesn't detect texlab in my $PATH and so the workaround I've come up with was linking ~/.nix-profile/bin/texlab to ~/.config/coc/extensions/coc-texlab-data/texlab

BTW, I really like coc-texlab so far, it's so much faster then coc-vimtex!

sumnerevans commented 3 years ago

I got it to work on NixOS using the following in my shell.nix file:

    shellHook = let
      # CoC Config
      cocConfig = {
        "texlab.path" = "${pkgs.texlab}/bin/texlab";
      };
    in
      ''
        mkdir -p .vim
        echo '${builtins.toJSON cocConfig}' | ${pkgs.jq}/bin/jq > .vim/coc-settings.json
      '';
