Indentation.

[yxhuvud]

lua-mode seems to default to indent 3 spaces.

Reading http://lua-users.org/wiki/LuaStyleGuide , it seems 2 is the most common number to indent, and that would therefore be a better default.

I agree that it would've been a better default value for lua-mode rewrite. But I'm reluctant to change it right now, because it has been like that for ages and I expect the following to happen after the change:

• if a user was happy with the default, she might get frustrated about lua-mode starting to indent code differently and about the necessity to touch configuration files to restore the way things were
• if a user was not happy with the default, chances are that lua-indent-level is already customized and the change will go completely unnoticed

So, atm, it seems somewhat pointless, or do I miss something?

[agladysh]

Sorry for a lazy question, but: is lua-indent-level documented and visible
to user?

If you mean "it's mentioned in lua-mode doc", then no, since there's no such doc :) But you sure can access it & read its docstring via M-x customize-group lua

[agladysh]

Ohh, well, I'll assume that finding that info is a common Emacs
knowledge, and I'm just an Emacs-illiterate (which I am).

I've just checked: it does require a bit of intuition or a knowledge how to use search box in "M-x customize" to find it. It is worth an extra mention in the readme (or commentary).

I think this could be closed, if one adds to the README:

;; change default indentation
(setq lua-indent-level 4)

I've added a quick summary of most useful customization variables (including lua-indent-level) to README.md.
