find-file "before" hook.

find-file "before" hook.

[Michal]

Hallo Group Members

I would like to invoke some action just before file is opened. I do not
see any hook that would allow it for me. find-file-hook is invoked after
file is opened.

Do YOu know any or have an idea on how to do it. I imagine 2 ways:
- overloading find-file - I do not like it.
- advising find-file. ... but maybe there is better solution:)

best regards,
Michal

Well, I am curious about what you might want to do before a file is opened.
Just off the top of my head, I can't think of anything you might want to do
before it is opened that you can't do equally as well after it is open :-)
But in answer to your later questions - have a look at ido, it must do
something similar in "overloading"/hijacking the find-file command, I
haven't bothered looking at how or what it does, but I do use the mode
occasionally. It definitely hijacks find-file and adds its own
functionality.

Best of luck
Peter

There are file handlers too. Look in for example sex-mode.el that
comes with nXhtml.

Hallo Lennart and Peter!
Thank You for Your help.
It looks like there is no thing in emacs that cannot be solved:)
