'smart' indentation

'smart' indentation

[Michael Powe]

hello,

i would like to have 'smart' indentation, à la some editors i use like
textpad.  if i indent a line, then when i press enter at the end of
the line, i want point to go to the indented position on the following
line.  i can't find the way to make this work.  it looks like
'adaptive-fill-mode' should do this, but it does not.  having to go
back and 'indent-region' is annoying.

thanks.

There is a function `newline-and-indent'. You want to bind this to
RET, I think (and you would probably find it is on C-j already).

I think you want

(global-set-key (kbd "RET") 'newline-and-indent)

Compared with Emacs standards, that indentation is rather dumb...

On the new line, invoke M-x indent-relative RET.  I like to use that
in text mode a lot, so I do (define-key text-mode-map (kbd "RET")
'indent-relative) in my ~/.emacs file.


Usually, Emacs does syntax-driven indentation.  This means that it
groks the syntax of your programming language and then uses the right
indentation level.

Does that imply that other editors don't have syntax driven
indentation???

No.

All I was saying is that the OP's idea of 'smart indentation'
corresponds to Emacs' idea of 'dumb indentation'.

I think most haven't, at least not for more than one or two languages.
It's not trivial to implement. I think most fake it like
indent-relative.

*shudder* It's a cold and cruel world out there, outside of Emacs.

Really ?  What do you then use to break a line ?

I meant TAB, not RET.  Sorry.

Huh?  But then why bother ?  It's already the default behavior !
