Apart from the lsp configuration you need to put the efm-langserver configuration file config.yaml.

I'm confused about why I also need a base configuration file when I have already configured Helix to send efm-langserver a configuration:

documentFormatting: true
languages:
  typescript:
    - formatCommand: yarn workspace foo prettier --stdin-filepath ${INPUT}
      formatStdin: true
  css:
    - formatCommand: yarn workspace foo prettier --stdin-filepath ${INPUT}
      formatStdin: true
  scss:
    - formatCommand: yarn workspace foo prettier --stdin-filepath ${INPUT}
      formatStdin: true
  html:
    - formatCommand: yarn workspace foo prettier --stdin-filepath ${INPUT}
      formatStdin: true

Edit: I tried duplicating this config in $HOME/.config/efm-langserver/config.yaml but haven't noticed a difference except that I no longer see this line in Helix's logs:

-- 2023-11-24T09:49:57.028 helix_lsp::transport [ERROR] efm-lsp-prettier err <- "2023/11/24 09:49:57 efm-langserver: no configuration file\n"
   2023-11-24T09:49:57.029 helix_lsp::transport [ERROR] efm-lsp-prettier err <- "2023/11/24 09:49:57 efm-langserver: reading on stdin, writing on stdout\n"

I don't think providing this base config is the problem because last week I was able to format tsx files with efm-langserver just fine without one. Something's changed since then and I'm just blind as to what it is.

Thank you for your response, mattn, btw

I got it working. I added this at $HOME/.config/efm-langserver/config.yaml

version: 2
log-file: /Users/thomas/.logs/efm-langserver
log-level: 1

And found this in the logs:

2023/11/24 10:22:39 format for LanguageID not supported: typescriptreact

So I just needed to add this to my Helix config

[[language-server.efm-lsp-prettier.config.languages.typescriptreact]]
formatCommand ="yarn workspace iot-ex prettier --stdin-filepath ${INPUT}"
formatStdin = true

I feel like this should've worked when I set the log file via commandline args

I tried getting some more info with args = [ "-logfile", "efmlog", "-loglevel", "2" ]. The efmlog file is created, but stays empty...

But maybe that was a problem with my Helix config
