Does the intelliJ plugin for toolchain save the file periodically?

If I do the following sequence:
• Press enter
• Press tab
• Press -
• Press space
And wait for a short second, it triggers the formatting action (which triggers on save). I have only tried this in Markdown files and in project.yaml, module.yaml, and *.module-template.yaml, and it only happens in module.yaml and .module-template.yaml.

This also happens for example when writing:

After I press : and space, after a short second it triggers the reformat again

I think the auto-sync of the project triggers on change with some debounce, and it's possible that it triggers a save, but don't take my word for it. @utikeev probably knows better

Oh wow, now that's 100% a bug. I have never seen this behavior

[joffrey]

Could you please share which IDEA version you're using?

2026.2.2

With dprint and ktfmt plugins installed:

dprint config:

{
  "json": {},
  "markdown": {
    "textWrap": "always"
  },
  "toml": {},
  "dockerfile": {},
  "yaml": {},
  "excludes": [
    "**/*-lock.json"
  ],
  "plugins": [
    "npm:@dprint/json@0.23.0",
    "npm:@dprint/markdown@0.23.3",
    "npm:@dprint/toml@0.8.0",
    "npm:@dprint/dockerfile@0.6.0",
    "npm:dprint-plugin-yaml@0.6.0"
  ]
}

Ah so maybe dprint is the thing that interacts with auto-sync in a strange way

[joffrey]

It would be worth trying without it and see

[James]

Oh, yes, it is 100% dprint - the problem is that the kotlin toolchain plugin is saving the file, which triggers "format on save" actions

[James]

It's saving the file when/while I type things

[joffrey]

As a workaround, you might try to disable auto-sync to see if that's the real cause

[James]

This solved it! THANK YOU!

[joffrey]

Ok so at least we know that. Now you'll have to click the sync button, Gradle-style, when you want to change the config (which is a pity given the speed of the sync 😆), but better than having this crazy reformat.

[James]

Yep, I prefer doing Cmd+Shift+A and find the Sync action manually anyways, it's okay 🙂

[joffrey]

For tracking, I opened this:
KTC-5835 Auto-sync interacts very poorly with format-on-save

FWIW, I’m seeing the same thing with Kotlin source files and Ktlint auto-formatting.

😞

Oh sorry, the issue was automatically turned private because one of the slack links was a JetBrains internal link. I forced the issue to be public now

[James]

Thanks! 😄
