Some operators can be automatically surrounded by spaces. This can
happen when the operator is typed, or later when the line is indented.
IDLWAVE can pad the operators ‘<’, ‘>’, ‘,’, ‘=’,
and ‘->’, as well as the modified assignment operators
(‘AND=’, ‘OR=’, etc.). This feature is turned off by default.
If you want to turn it on, customize the variables
idlwave-surround-by-blank and idlwave-do-actions and turn
both on. You can also define similar actions for other operators by
using the function idlwave-action-and-binding in the mode hook.
For example, to enforce space padding of the ‘+’ and ‘*’
operators (outside of strings and comments, of course), try this in
.emacs
(add-hook 'idlwave-mode-hook
(lambda ()
(setq idlwave-surround-by-blank t) ; Turn this type of actions on
(idlwave-action-and-binding "*" '(idlwave-surround 1 1))
(idlwave-action-and-binding "+" '(idlwave-surround 1 1))))
Note that the modified assignment operators which begin with a word
(‘AND=’, ‘OR=’, ‘NOT=’, etc.) require a leading space to
be recognized (e.g., vAND=4 would be interpreted as a variable
vAND). Also note that since, e.g., > and >= are
both valid operators, it is impossible to surround both by blanks while
they are being typed. Similarly with & and &&. For
these, a compromise is made: the padding is placed on the left, and if
the longer operator is keyed in, on the right as well (otherwise you
must insert spaces to pad right yourself, or press simply press Tab to
repad everything if idlwave-do-actions is on).
nil) ¶Non-nil means enable idlwave-surround. If non-nil,
‘=’, ‘<’, ‘>’, ‘&’, ‘,’, ‘->’, and the
modified assignment operators (‘AND=’, ‘OR=’, etc.) are
surrounded with spaces by idlwave-surround.
t) ¶Non-nil means space-pad the ‘=’ in keyword assignments.
