idlwave: Actions

 
 4.9 Actions
 ===========
 
 _Actions_ are special formatting commands which are executed
 automatically while you write code in order to check the structure of
 the program or to enforce coding standards.  Most actions which have
 been implemented in IDLWAVE are turned off by default, assuming that the
 average user wants her code the way she writes it.  But if you are a
 lazy typist and want your code to adhere to certain standards, actions
 can be helpful.
 
    Actions can be applied in three ways:
 
    • Some actions are applied directly while typing.  For example,
      pressing ‘=’ can run a check to make sure that this operator is
      surrounded by spaces and insert these spaces if necessary.
      Pressing <SPC> after a reserved word can call a command to change
      the word to upper case.
    • When a line is re-indented with <TAB>, actions can be applied to
      the entire line.  To enable this, the variable ‘idlwave-do-actions’
      must be non-‘nil’.
    • Actions can also be applied to a larger piece of code, e.g., to
      convert foreign code to your own style.  To do this, mark the
      relevant part of the code and execute ‘M-x expand-region-abbrevs’.
      Useful marking commands are ‘C-x h’ (the entire file) or ‘C-M-h’
      (the current subprogram).  Code Indentation, for
      information how to adjust the indentation of the code.
 
  -- User Option: idlwave-do-actions (‘nil’)
      Non-‘nil’ means performs actions when indenting.  Individual action
      settings are described below and set separately.
