idlwave: Code Indentation
4.1.1 Code Indentation
----------------------
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.
Actions, for information how to impose additional formatting
conventions on foreign code.
-- User Option: idlwave-main-block-indent (‘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.
-- User Option: idlwave-block-indent (‘3’)
Extra indentation applied to block lines. If you change this, you
probably also want to change ‘idlwave-end-offset’.
-- User Option: 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.
