Use Intellij built-in code formatter

[mlthlschr]

It would be great to integrate the plugin with the built-in code formatter (CTRL-ALT-L). This would not only be easier regarding the shortcut, but would also give the possibility of checking "reformat code" when commiting code and reformat it automatically.

As an example, the plugin of prettier in the world of javascript is capable of doing so.

Good idea! And thanks for the example link!
I'll take a look at the viability of this for the next update (0.4.0 is being submitted today) :)

Implemented here 😁

Be wary though, even with "Reformat" during a commit, not all ktlint rules are auto-fixed by the tool itself. Some need to be manually fixed, such as no-wildcard-imports for example

[mlthlschr]

Wow, that was quick! :-D Thanks for that, I am going to take a look at it.

The no-wildcard-imports issue goes a little bit deeper, right? I know that you can set this setting in the intellij code formatting options, maybe it is possible to trigger it somehow?

[nbadal]

Yeah for that one specifically there's a few IDE settings to turn off the wildcard threshold in Settings > Editor > Code Style > Kotlin > 'Imports' Tab

The command line utility for ktlint has a flag to set some IntelliJ settings, which might include that, but I'm holding off on implementing that part because they're talking about transitioning to an .editorconfig-based solution soon.

One improvement I might make as well is to turn off the "Format with ktlint" action for rules that are not auto-correctable.

Closing since this particular issue is merged and ready for 0.5.0, but happy to continue the discussion 😁
