force reparse of file variables

force reparse of file variables

[Sam Halliday]

Hi all,

Is there a way to force (re)-load all the file variables in a buffer?

I have a template (with yasnippet) that populates files of certain types and derives some file variables (such as the 'compile-command), but I need to save/open to load it.

Best regards,
Sam

Do that lots of times.
I save the file, then revert-buffer.

C-x C-v RET

IOW, `find-alternate-file' should do what you want, I think.  It kills
the buffer and revisits the file.

Thanks Dan. That works a charm. The one problem is that it means that in my workflow if I create a new buffer, that has a file template, then I always save the file instead of waiting for the user to decide when to save it. If there was a way to reload the File-Variables for an unsaved buffer, that'd be even better.

FYI, my templating is implemented here

I guess something like M-: (hack-local-variables) RET should work.


Michael.
