this will create file without name clash at the same location: `file=$(mktemp "$kak_buffile.XXXXXXXXX")`, and the name will be stored in `file`, you then can format, pipe back, and delete it in single shell call. ---

I made it work without writing a temp file. The eslint formatter `json` includes the fixed file in its output if `--fix-dry-run` is set. I then use `jq` to parse the JSON output: ```auto define-command -hidden eslint-format %{ evaluate-commands -draft -no-hooks -save-regs '|' %{ # Select all to format execute-keys '%' # eslint does a fix-dry-run with a json formatter which results in a JSON output to stdout that includes the fixed file. # jq then extracts the fixed file output from the JSON. -j returns the raw output without any escaping. set-register '|' %{ %sh{ echo "$kak_selection" | \ npx eslint --format json \ --fix-dry-run \ --stdin \ --stdin-filename "$kak_buffile" | \ jq -j ".[].output" } } # Replace all with content from register: execute-keys '|' } } ``` How can I restore the cursor position after formatting (a simple mark? somehow `execute-keys 'Z'` leaves me with an empty `^` so that `execute-keys z` afterwards returns an error) I added this as an alternative to the Wiki: [https://github.com/mawww/kakoune/wiki/Lint#javascript-eslint](https://github.com/mawww/kakoune/wiki/Lint#javascript-eslint) ---

I think you can make it into a package ---

It is done, a **successful lint/format setup for js/ts:** > **[GitHub - schemar/kak-jsts: JavaScript / TypeScript extension for the Kakoune...](https://github.com/schemar/kak-jsts)** > > JavaScript / TypeScript extension for the Kakoune editor. - GitHub - schemar/kak-jsts: JavaScript / TypeScript extension for the Kakoune editor. @jssee do you still need this? ๐Ÿ˜‰ I want to add it to the Wiki, but I am not sure where. Under [Languages](https://github.com/mawww/kakoune/wiki/Languages)? The currently linked TypeScript repo doesnโ€™t work with the latest Kakoune anyways, I could replace it. Kakoune has built-in support for TypeScript syntax highlighting by now anyways, if I see that correctly. By the way, I have on issue that I cannot fix. The lint command requires the path to the globally installed `node_modules`. I cannot set it as an option with `$kak_opt_...` as it seems that wonโ€™t be available due to how [`lint.kak`](https://github.com/mawww/kakoune/blob/master/rc/tools/lint.kak) is implemented. Any way how that could be done better than asking users of the plugin to replace the whole `lintcmd` in case it isnโ€™t the default path for them? Maybe @robertmeta or @alexherbo2 have an idea? ๐Ÿค” Anyways, I hope this will help others ๐Ÿ˜Š ---

I donโ€™t think this should go to that wiki page, as it is about builtin language support (Unless you wish to contribute your work to Kakoune directly ๐Ÿ™‚) . I think you should add tags to the repo so it could be visible on plugin page at [Kakoune - Plugins](https://kakoune.org/plugins.html) ---

Ok, it is done and working. `npm list` to the rescue. Unfortunately it is very slow, but now it should work on most systems and linting runs asynchronously anyways. ```auto set window lintcmd 'run() { cat "$1" | npx eslint --format "$(npm list -g --depth=0 | head -1)/node_modules/eslint-formatter-kakoune/index.js" --stdin --stdin-filename "${kak_buffile}";} && run ' ``` I am really happy with how this worked out in the end. Linting and formatting works very well now. Was not super straight-forward to set up ๐Ÿ˜… If anyone comes here looking for a working integration with `eslint`, please try the kak-jsts project I linked above ๐Ÿ™‚ ---

I have done shockingly little to get my TS setup working well (linting, prettier, autocomplete, etc). Thanks to kak-lsp! ---

That sounds great. Did you integrate eslint with lsp-kak formatting and diagnostics? ---
