Re: disable automatic indentation in table like environments

[Thibaut Verron]

Dear all,

For what it's worth, I have put up together a while ago an alternative function for `LaTeX-indent-tabular`. My biggest problem with the old function was its insistence on indenting hanging ampersands as if they were not hanging. It makes it impossible to break long lines, since AUCTeX then wants to indent the new line to the last column of the previous one.

The function is attached, it does not call `LaTeX-hanging-ampersand-position`.

I cannot guarantee that it always does the right thing, but so far it matched all my expectations.

Best,

Thibaut

I don't have this configuration, yet I haven't changed the default configuration.
Value:
(("verbatim" current-indentation)
  ("verbatim *" current-indentation)
  ("filecontents" current-indentation)
  ("filecontents *" current-indentation)
  ("tabular" LaTeX-indent-tabular)
  ("tabular *" LaTeX-indent-tabular)
  ("align" LaTeX-indent-tabular)
  ("align *" LaTeX-indent-tabular)
  ("array" LaTeX-indent-tabular)
  ("eqnarray" LaTeX-indent-tabular)
  ("eqnarray *" LaTeX-indent-tabular)
  ("displaymath")
  ("equation")
  ("equation*")
  ("picture")
  ("tabbing"))

Indentation in an environment is controlled by a function. I find that
the LaTeX-indent-tabular function is not very satisfactory in some
cases. The solution would be to write a function that does what you
want, but that's Emacs-lisp code.  It is one of the easiest computer
languages to learn and use that I know ...
