"Invalid function: 0"

[kjsdb_v2]

I keep getting this message "mumamo-do-fontify-2: mumamo-do-fontify m=php-mode, s/e=1465/1586 syn-min/max=1470/5225: Invalid function: 0" for no apparent rhyme or reason.

Hi kjsdb_v2,

Thanks for the bug report, but I am afraid you have to give me an example of how to reproduce this if you want me to fix it.

[kjsdb_v2 (kjsdb)]

Maybe some backtrace will help. I removed the syntax tables because they seemed to add little, simply dots.

Thanks kjsdb_v2, but I am afraid I still need an example. The backtrace might be helpful but it has just a small part of the information needed in a situation like this.

Please try to reproduce this starting from a fresh Emacs with just nXhtml loaded. You can start a new Emacs with this with the command

   M-x emacs-Q-nxhtml

PS: When sending backtraces it is useful uploading them as attachments instead of pasting them. Reading here will be much easier and the backtrace will not get corrupted.

[kjsdb_v2 (kjsdb)]

Sorry, you're on your own with that. I'm not allowed to give away our code, which is what giving you an example would mean.

BTW, what will emacs-Q-nxhtml do when emacs is a bash alias to 'emacsclient -t --alternate-editor=""', and the current instance was started with that?

Anyway, it doesn't happen if I only load that. Nor when I include my php configuration as well. I will see if I can narrow it down in my configuration.

[lborgman (lennart-borgman)]

Perhaps you can make a simple dummy example? It does not have to be working code, nXhtml does not care about that ;-)

emacs-Q-nxhtml looks for the Emacs variable `invocation-name'. What is that in your case?

Does the command emacs-Q-nxhtml work in your Emacs?

I have seen similar errors that looked quite weird from the beginning. In the end it mostly turns out that there was a bad assumption in one of the major modes involved. (This is one reason I am shipping some major modes with nXhtml.)

Pleas tell me what you find out. Good luck.

[kjsdb_v2 (kjsdb)]

Okay, well the closest I can say is it seems to be be dependent on nxhtml, flymake, *and* test-case-mode (http://nschum.de/src/emacs/test-case-mode/ and especially http://github.com/ieure/test-case-mode which is a changed version I use to test php code)

;; flymake
(require 'flymake)
(add-hook 'find-file-hook 'flymake-find-file-hook)

;; test-case-mode
(autoload 'test-case-mode "test-case-mode" nil t)
(autoload 'enable-test-case-mode-if-test "test-case-mode")
(autoload 'test-case-find-all-tests "test-case-mode" nil t)
(autoload 'test-case-compilation-finish-run-all "test-case-mode")
(add-hook 'find-file-hook 'enable-test-case-mode-if-test)

I've also tried it without the find-file-hooks and it makes no difference. And yes, the files I see it on are only my unit test files.

[lborgman (lennart-borgman)]

Looking at the backtrace more closely I see a problem there. It actually says that nxhtml-mumamo is not defined.

The name nxhtml-mumamo is not autoloaded, only the longer name nxhtml-mumamo-mode is autloaded. I have forgotten that php-mode.el uses the shorter name.

Could you please try and change to the longer name at line 287 in php-mode.el and see if that helps. (Don't forget to also recompile php-mode.el if you have it byte compiled.)

[kjsdb_v2 (kjsdb)]

That works :) Thanks.

[lborgman (lennart-borgman)]

Oh, fine. Sorry for the trouble and thanks for helping to solve this.

I think I should remove the shorter names to avoid this kind of trouble. (I have only kept them for backward compatibility.)

[kjsdb_v2 (kjsdb)]

Sorry, but this doesn't seem to have fixed it after all. It doesn't happen all of the time, only most of the time, and I obviously hit a time when it didn't happen when I tested it before.
