Describe the bug / provide steps to reproduce it

Under macOS, assume that texlab, the latex extension version 0.0.7, and Skim are installed, and that texlab has been configured, for instance wirth the following in settings.json

  "lsp": {
    "texlab": {
      "settings": {
        "texlab": {
          "latexindent": {
            "modifyLineBreaks": true
          },
          "build": {
            "onSave": true,
            //"executable": "lualatex",
            //"args": [
            //  "--shell-escape",
            //  "--synctex=1",
            // "%f",
            //],
            "forwardSearchAfter": true
          },
          "forwardSearch": {
            "executable": "/Applications/Skim.app/Contents/SharedSupport/displayline",
            "args": [
              "-r",
              "%l",
              "%p",
              "%f"
            ]
          }
        }
      }
    }
  },

(Nothing changes if the commented command is uncommented.)
Usually, pressing cmd-S under macOS will compile, if necessary, and then open Skim (the location is not always correct, but it us often the previous one, I will file a separate ticket).

However, some commit on Sept Thu 26, broke this, and no compilation occurs, nor is Skim opened.

@mocenigo I'm facing the same error.

This happened after update zed version. Before I had #18450 which is already fixed

I can also confirm the bug when building it from source (87cc20f) running Arch Linux

Not sure if relevant but I get the same error as above. The logs also shows that the command is sent (texlab - RPC messages):

{"jsonrpc":"2.0","id":4,"result":[{"build":{"onSave":true},"chktex":{"onEdit":true}}]}

[mocenigo]

Yeah, it seems a problem with onSave. The other functionality works, including syncing with the pdf (although in the wrong place).

Could you clarify "Save notifications are reported only to servers that signed up for a given extension". Does this mean file extension, and is this signing up something that the language serve do itself or something that Zed extensions can configure?

[lnay]

For reference, texlab still receives textDocument/documentHighlight from just moving the cursor, but no longer receives textDocument/didSave starting from that commit.

[lnay]

The first affected release for this particular issue would have been v0.156.0 on 9th October. So @srteppei you have a different problem, you can raise an issue on the extension repository if you are still have this issue on Zed v < 0.156.0.

[lnay]

Just read slightly more into the original PR and LSP spec. Here's another piece of the Zed log in case it's relevant (or is it only didChangeWatchedFiles that matters?):

2024-10-13T23:14:40.825723666+01:00 [INFO] starting language server process. binary path: "/path/to/texlab", working directory: "/path/to/workspace/", args: []

The changelog for texlab contains the following from 2022:

• BREAKING: Use client-side file watching instead of server-side notifications (workspace/didChangeWatchedFiles)

[srteppei]

Well I opened here the error cause just was the same message, don't know what is LaText.

If this is not the place, where should I open it @lnay ?

[osiewicz]

@lnay

Could you clarify "Save notifications are reported only to servers that signed up for a given extension". Does this mean file extension, and is this signing up something that the language serve do itself or something that Zed extensions can configure?

Yes, I meant file extensions there. It is on a language server (via file system watchers) to do it and not the Zed extension.

[lnay]

@osiewicz is there a way to get a log for the RPC responses from the server from before I manage to open "debug: open language server logs"? I cannot find didChangeWatchedFiles in either the Zed logs or the language server logs by the time I get it open.

[osiewicz]

Yeah, it's a common pain point of LSP log view. You can run zed with RUST_LOG=lsp=trace zed --foreground; that'll print all logs to the console you run it from.

[cambordas]

@mocenigo I compiled today my zed with this commit ebc3031 and onSave is working again. I might try to compile with the lastest commit as of today, but I have a feeling it would also work.

[lnay]

Just checked the current release, everything is fine now. It seems there has been a discussion about how to interpret the LSP spec: #19183

[lnay]

I think this can be closed as completed.
