Can I turn on some minor mode on specific files?

Can I turn on some minor mode on specific files?

[Hongxu Chen]

Hi list,

   I sometimes do not need to spell check for all the text files, but
   only a few specific files on-line. So I would like the spell checker
   like flymake only turned on for these files. Is there a way to do so?
   I guess that the file-local variable might help, however I am not
   familiar with the `eval' syntax.

   Thanks in advance.


Regards,
Hongxu Chen

Just put: -*- mode:flyspell -*-
on the first or second line.


Alternatively, put:

Local Variables:
mode: flyspell
End:

within the last 512 bytes of the file.



If you want to activate it for a whole familly of files determined by
their path (eg. extension, name or directory component), you can use
auto-mode-alist.

It works, thanks, Pascal.
Didn't realize that I could use `mode' that way. Seems that it specifies
the additional minor-mode, but it is not a variable(at least `C-h v'
cannot fetch it). So what is the mechanism?

Another question, is the local variable specified should be limited to
be within 512 bytes exactly? I haven't found the related docs yet.

M-: (info "(emacs)Specifying file variables")

But it complains:

  Info-find-file: Info file emacs does not exist

I am runnning on Emacs 24.3.

Also, Pascal's advice is NOT correct since adding `mode' in the modeline
would change the major mode rather than minor modes, and the right way
is to append the following:

# Local Variables:
# eval: (flyspell-mode 1)
# End:

If you are on debian, try

        sudo apt-get install emacs23-common-non-dfsg

Thanks, I can get the info page now:-)

You should of course put your major mode first, but you can add as many
minor modes you want:

-*- mode:text;mode:hs-minor;mode:flyspell -*-

So in this way I have to add the major-mode explicitly then?

Yes, it seems to be the case, indeed.
