max-lisp-eval-depth problem

[hajovonta]

Emacs version: 28.0.50

Sometimes when I open a groovy file, I get "File mode specification error: (error Lisp nesting exceeds 'max-lisp-eval-depth')" error in minibuffer.
Increased the max-lisp-eval-depth to 10000, but that didn't solve the problem.

Tried to debug, and the last function executed before the error was normal-mode, with something like "couldn't load files.el".

Due to the error, I don't get syntax coloring in groovy-mode. But if I M-x normal-mode after the error, I get my file colored (and another error message).

Please help investigating the problem.

Could you share an example file that has this problem?

[hajovonta]

This file below produces the error for me if I save it as 'test.groovy' and open it in Emacs.
Sensitive data redacted.

import com.company.ci.common.Context
import static com.company.ci.common.Params.*
import com.company.ci.common.jobname.CommonJobs
import groovy.transform.Field


@Field
Context ctx = new Context(sourceRepo: SourceRepo.REPO,
        buildType: BuildType.RELEASE,
        jenkinsSlave: JenkinsSlave.MY_LABEL,
        scriptName: this.class.name)


freeStyleJob(CommonJobs.SERVER_DEPLOYMENT.name) {
    with ctx.jobSetup()
    parameters ctx.gerritRefspecParam()
    scm ctx.sourceScm(ctx.scm_Gerrit_This_Patchset() + [clean: true])
    publishers {

            conditionalSteps {
                condition {

                }
            }
        }
    }
}

The problem is that the error prevents the mode to run properly, e.g. some hooks and minor modes are not loaded

[hajovonta]

Strange, but I could make a workaround by evaluating these:

(add-hook 'groovy-mode-hook #'company-mode-hook)
(add-hook 'groovy-mode-hook #'company-mode)

This way it complains about company-mode-hook, but then loads company-mode fine, and I also get syntax coloring. If I leave the company-mode-hook out, then I get neither.

I'm unable to get an error with that file. Could you try M-x toggle-debug-on-error before opening the file, to get a traceback?

If you can get a traceback, please post it here.

[hajovonta]

I tried this, but I don't get a Backtrace window. The error is shown in the minibuffer and in the Messages but that's it.

What else is in your groovy-mode-hook and prog-mode-hook? Can you replicate the issue with emacs -q, loading groovy-mode.el and opening the test file you've shared?

[hajovonta]

groovy-mode-hook contains:
(inf-groovy-keys company-mode company-mode-hook groovy-mode)
and prog-mode-hook is nil.

I tried the procedure you insisted, but got the following error when trying to load groovy-mode.el:
*** Eval error *** Cannot open load file: No such file or directory, s
I'm sure it's some blatant but I'm not skilled in debugging emacs.

[Wilfred Hughes]

*** Eval error *** Cannot open load file: No such file or directory, s

Sorry, I should have mentioned. When you start with emacs -q, qou'll need to run M-x eval-buffer on dash.el and s.el first so you have the necessary dependencies.
