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. See 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.
