Configuring Texlab for Neovim on macOS

[dpo]

Hello. I'm using Texlab with LunarVim and having trouble configuring it. I asked a question over at LunarVim, but haven't received any response.

My tentative configuration is as follows:

vim.list_extend(lvim.lsp.automatic_configuration.skipped_servers, { "texlab" })

require('lspconfig').texlab.setup({
  setting = {
    texlab = {
      forwardSearch = {
        executable = '/Applications/Skim.app/Contents/SharedSupport/displayline',
        args = { "-b", "%l", "%p", "%f" },
      },
      build = {
        onSave = true,
        forwardSearchAfter = true,
      },
      chktex = {
        onOpenAndSave = true,
      },
      formatterLineLength = 0,
    },
  },
})

Calling :TexlabBuild directly works, but :TexlabForward fails with the message Search Unconfigured (though I think I configured it above).

In addition, build on save isn't working (i.e., saving doesn't trigger a build).

Is there something visibly wrong with the configuration above? If not, how does one debug this kind of issue (I'm new to Neovim and Lua)?

Thanks!

Just pinging here in case someone has an idea. Still unable to use Texlab.

Hey, can you try creating a log file using texlab -vvvv --log-file=/tmp/texlab.log?
It looks like your client does not pass the LSP config to texlab. Building should work out of the box (it uses latexmk by default) but forward search requires extra configuration.

Do you mean that I have to have Neovim somehow fire up Texlab with those arguments? I have to investigate how to do that. If I simply write the command in a terminal, and then open Neovim and build, the log file remains empty.

[pfoerster]

Yeah, Neovim should pass those arguments to texlab or you can try and see if Neovim logs the JSON-RPC messages exchanged between the server and the client.

Ok I managed to get the server to start with the command you gave above (though I had to replace = with a space, right?). Indeed, it looks like the settings are not passed to texlab. Thank you.

Here's what I see in the log file:

DEBUG - < {"jsonrpc":"2.0","params":{"settings":{"texlab":{"build":{"onSave":false,"executable":"latexmk","forwardSearchAfter":false,"args":["-pdf","-interaction=nonstopmode","-synctex=1","%f"]},"forwardSearch":{"args":[]},"auxDirectory":".","diagnosticsDelay":300,"latexFormatter":"latexindent","chktex":{"onEdit":false,"onOpenAndSave":false},"bibtexFormatter":"texlab","formatterLineLength":80,"latexindent":{"modifyLineBreaks":false}}}},"method":"workspace\/didChangeConfiguration"}
