Re: how to restrict the numbers of chars in a buffer/file

Uwe> Hello Is there any possibility that a given buffer/file only Uwe> admits say 150 chars but not more? Yes. See the variables `write-file-hooks' and `local-write-file-hooks'. You would put something like (lambda () (> (buffer-size) 150)) on `local-write-file-hook' with `add-hook'. The function for `write-file-hooks' would have to be more complex, as it would need to check which buffers it applies to somehow. You might also want to call `set-buffer-modified-p' appropriately, and probably `warn' or `error' to tell the user that the maximum file size had been exceeded. I'd need to know more about the use case to say more about what you *should* do (which hook to use, how to make it convenient, etc), but that should give you an idea of *how* to do it. -- School of Systems and Information Engineering http://turnbull.sk.tsukuba.ac.jp University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Ask not how you can "do" free software business; ask what your business can "do for" free software.
