Can I use detekt to prevent the use of a field in one of my classes? Typically I would make the field private, but in this case I can't. so i just want to warn my team.

[Brais Gabin]

The first idea is deprecation

[Brais Gabin]

We had a forbidden method call but I think that it doesn't work for fields or properties

[Brais Gabin]

I think that we have an issue requesting that

[Colton Idle]

hm. that might work.

[LeoColman]

My first idea is using _ to designate fields that one shouldn't touch.

val _aDelegate = abc()
val a by aDelegate

[Colton Idle]

hm. apparently you can forbid properties?

[Colton Idle]

gotta look into it though.

[Brais Gabin]

Nice! I didn't remember that pr. Then you have lots of options :)

[Colton Idle]

Am I going crazy, or are the docs for setting up forbiddenMethodCall wrong? https://detekt.dev/docs/rules/style/#forbiddenmethodcall
How the heck am I suppose to mark a field as forbidden?

[Brais Gabin]

Looking at the PR you linked you can not forbid a "field" you can forbid the get and the set of a property. If there are issues with the documentation any PR is more than welcome. And, if you don't know how to do something we will need more information than that to try to help you.

[Colton Idle]

yeah. apparently setting methods as an array doesn't work. but you can just set a
-method
-method
-method

so I tried going that route, but still no luck anyway because like you said. a field apparently can't be prevented. going to to to write a lint rule instead. thanks
