Use of compile is not documented or not working

[ezaquarii]

I'm trying to get gdb working woth go and I need to re-compile test before debugging:

(add-to-list 'dape-configs
      '(gdb-go
    modes (go-mode)
    command "gdb"
    command-args ("--interpreter=dap")
    compile "go build"
    :request "launch"
    :program "a.out"
    :args []
    :stopAtBeginningOfMainSubprogram nil)))

When launching dape, it says:

Wrong type argument: stringp, "go build"

I tried to toggle debug on error, but it's not triggered.

How to use cutsom compile method on debug?

What version do of dape do you have?

Your example looks correct. Tried on my machine with success. Have you set dape-compile-fn to any other value the the default 'compile?

Ok, I discovered what was the issue. My config uses (setq dape-cwd-fn 'projectile-project-root). However, this particular project did not have .git directory nor .projectile.el, hence projectile-project-root was nil.

As a result, it was b0rking deep inside compile.

I propose some more intelligent version of default dape-cwd-fn that falls back to default-directory:

(defun dape-projectile-or-default-directory ()
  (unless (projectile-project-root)
    (projectile-project-root)
    default-directory))

Overall, it turned out to be my configuration issue.
