idlwave: Case of Completed Words

 
 4.4.1 Case of Completed Words
 -----------------------------
 
 IDL is a case-insensitive language, so casing is a matter of style only.
 IDLWAVE helps maintain a consistent casing style for completed items.
 The case of the completed words is determined by what is already in the
 buffer.  As an exception, when the partial word being completed is all
 lower case, the completion will be lower case as well.  If at least one
 character is upper case, the string will be completed in upper case or
 mixed case, depending on the value of the variable
 ‘idlwave-completion-case’.  The default is to use upper case for
 procedures, functions and keywords, and mixed case for object class
 names and methods, similar to the conventions in the IDL manuals.  For
 instance, to enable mixed-case completion for routines in addition to
 classes and methods, you need an entry such as ‘(routine . preserve)’ in
 that variable.  To enable total control over the case of completed
 items, independent of buffer context, set
 ‘idlwave-completion-force-default-case’ to non-‘nil’.
 
  -- User Option: idlwave-completion-case
      Association list setting the case
      (UPPER/lower/Capitalized/MixedCase...)  of completed words.
 
  -- User Option: idlwave-completion-force-default-case (‘nil’)
      Non-‘nil’ means completion will always honor the settings in
      ‘idlwave-completion-case’.  When ‘nil’ (the default), entirely
      lower case strings will always be completed to lower case, no
      matter what the settings in ‘idlwave-completion-case’.
 
  -- User Option: idlwave-complete-empty-string-as-lower-case (‘nil’)
      Non-‘nil’ means the empty string is considered lower case for
      completion.
