Spaces instead of tabs in new mode

Spaces instead of tabs in new mode

[Paulo J. Matos]

Hi,

I have programming and indent-line for my new major mode but tabs are
not shown as spaces and are too big. How can I program emacs to show
the tabs as spaces and have a way to program the number of spaces per
tab?

Thanks,

Hi, you can put this in your .emacs:

,----
| (setq-default indent-tabs-mode nil)
`----

to avoid tab indenting.

I programmed a new mode. Can't I say that specifically for this mode I
want this to always happen?

Put (setq indent-tabs-mode nil) in the function that turns on your mode (e.g.
`foo-mode').

This variable is automatically buffer-local, so when you use `setq' (not
`setq-default') to set it, you are setting it only in the current buffer, that
is, the buffer that is in your mode.

Great, that's what I wanted! :)

OK, thanks. Should I set that variable in my new mode or should I leave
it to the user to set to whatever value it wants?
