How can I get a find-file hook function to run for only a specific file?
Conceptually, I'd like this: (find-file "myfile.txt" 'myfile-hook-function)
I want myfile-hook-function to run only on the first call to find-file, i.e. when the file is opened and loaded, but not if the file is already loaded.
I do this now:
(add-hook 'find-file-hook 'myfile-hook-function)
(find-file "myfile.txt")
(remove-hook 'find-file-hook 'myfile-hook-function)
This works, but it seems hokey.

I don't think you can get something much cleaner, no.
But the above should use
(add-hook 'find-file-hook 'myfile-hook-function)
(unwind-protect (find-file "myfile.txt")
(remove-hook 'find-file-hook 'myfile-hook-function))
So that the remove-hook is also executed when find-file signals
an error.
