Hey @chimpanstache - any chance you could share your users_controller.rb file? If not, could you potentially try to format it while removing private content and get it down to a small reproduction? I can't do anything without a little more information unfortunately.

[chimpanstache]

Hey @kddnewton, there are only 2 contexts where value is appearing in that file, which are very same:

    result =
      estimate_duration.call(
        params: params,
      )
    if result.success?
      duration = result.value!

estimate_duration being an instance of this class:

class EstimateDuration
  include Wisper::Publisher
  include Dry::Monads[:result]
  extend Dry::Initializer


  def call(params:)
      ...

copilot explanation here if helpful:

Dry::Monads::Result can be either a Success or a Failure object. Both Success and Failure objects respond to the value! method.

In the case of a Success object, value! will return the value that the Success object is wrapping. However, if result is a Failure object, calling value! will raise an error.

Let me know if a larger code sample is necessary, thank you for helping me

[kddnewton]

value in this case is a method being called within syntax tree, it doesn't have to do with your file specifically. I imagine there's some place in your code that is calling something like:

foo.()

Do you see anything like that?

[chimpanstache]

Indeed, here it is:

    Dry::Matcher::ResultMatcher.(result) do |m|
      ...

[kddnewton]

Great! Now that we've found that, can you tell me the version of the syntax_tree gem that you have installed? That performs the actual formatting.

[chimpanstache]

Nice, there it is:

❯ gem list syntax_tree

*** LOCAL GEMS ***

syntax_tree (6.2.0)
syntax_tree-haml (4.0.3)
syntax_tree-rbs (1.0.0)

[kddnewton]

Is there anywhere else in that file that has calls like that? I'm still not quite able to reproduce here. (Thank you for your patience!)

[kddnewton]

Actually even better, could you run stree format path/to/file and give me the backtrace? That would be super helpful.

[chimpanstache]

No worries! No, it's the only place in that file. Here is the full backtrace :

[kddnewton]

Ah-ha! Found it. Thanks! That'll be fixed in the next release

[chimpanstache]

Fantastic! Thank you for your help. Looking forward the next release

[kddnewton]

In the meantime you can take the following steps:

1. Change it to Dry::Matcher::ResultMatcher.call(result) do |m|
2. Add a # stree-ignore comment before the line with the issue
3. Ignore the whole file

[chimpanstache]

# stree-ignore for the win!
