opening a buffer as read-only as default

opening a buffer as read-only as default

[rotlas]

Which is the simplest way to have Emacs opening all files as read-only? That
is not only by using C-x C-r  but also when selecting a file in a directory
buffer. And also preventing C-x C-f from opening a file as writable. I would
like it to be possible to toggle the read-only state, though.

'v' to just view it. You could add another hook to find-file-hook  
that all files are opened read-only...

Don't just do something, sit there.

,----[ C-h k v ]

| It is bound to v, <menu-bar> <immediate> <view>.
| (dired-view-file)

| In Dired, examine a file in view mode, returning to Dired when done.

(add-hook 'find-file-hook (lambda () (setq buffer-read-only t)))

,----[ C-h k C-x C-q ]
| C-x C-q runs the command toggle-read-only
|   which is an interactive compiled Lisp function in `files.el'.
| It is bound to C-x C-q.
| (toggle-read-only &optional arg)
|
| Change whether this buffer is visiting its file read-only.
| With prefix argument arg, make the buffer read-only if arg is
| positive, otherwise make it writable.  If visiting file read-only
| and `view-read-only' is non-nil, enter view mode.

Thanks, Peter and Kevin for great answers. Now I don't have to undo all
unintentional modifications of files everytime I compile...
