Like all Emacs programming modes, IDLWAVE performs code indentation.
The TAB key indents the current line relative to context.
LFD insert a newline and indents the new line. The indentation is
governed by a number of variables. IDLWAVE indents blocks (between
PRO/FUNCTION/BEGIN and END), and
continuation lines.
To re-indent a larger portion of code (e.g., when working with foreign
code written with different conventions), use C-M-\
(indent-region) after marking the relevant code. Useful marking
commands are C-x h (the entire file) or C-M-h (the current
subprogram). The command C-M-q reindents the entire current
routine. See Actions, for information how to impose additional
formatting conventions on foreign code.
2) ¶Extra indentation for the main block of code. That is the block between the FUNCTION/PRO statement and the END statement for that program unit.
3) ¶Extra indentation applied to block lines. If you change this, you
probably also want to change idlwave-end-offset.
-3) ¶Extra indentation applied to block END lines. A value equal to negative
idlwave-block-indent will make END lines line up with the block
BEGIN lines.
