Specifying regions in mmm-mode with start and end index and avoid parse

[cjohansson]

I would like to be able to use mmm-mode with my major mode phps-mode, in phps-mode I automatically get regions specified where inline code (HTML, XML, etc) can be used based on semantic lexer tokens with start and end character indexes of the current buffer, this means there is no need for mmm-mode to parse the buffer in any way.

Is there a way I can send regions to mmm-mode manually and prevent it from parsing the buffer?

Ideally I would like phps-mode as primary mode and then web-mode as mode for the inline areas of a phps-mode buffer. After that I would like css-mode and js2-mode to trigger based on regex regions in web-mode

You can try using mmm-make-region, I think.

Another option would be to save some parsing information in the buffer via text properties. Then define the submodes using FRONT and BACK with function values. Said functions can search for the aforementioned text properties.

Ok thanks will try using that function

Ok it works but I get a warning: Invalid or undefined submode class: phps-web, it is possible to avoid it?

This is my code:

(setq phps-mode-inline-mmm-submode 'web-mode)
(mmm-add-mode-ext-class 'phps-mode nil 'phps-web)

;; The lexer does this
(when (and (boundp 'phps-mode-inline-mmm-submode)
               phps-mode-inline-mmm-submode
               (fboundp 'mmm-make-region))
      (mmm-make-region phps-mode-inline-mmm-submode start end))

Try using t instead.

If CLASS
is the symbol t, MMM Mode is turned on in all buffers matching MODE
and EXT, but no classes are activated.

Try disabling whitespace-mode? I'm not quite sure what would make it work in this situation.

[cjohansson]

Yes that seemed to resolve that issue, will dig further.. it seems to work with whitespace-mode as well.. Maybe it was a one time error
