An object method is not uniquely determined without the
object’s class. Since the class is almost always omitted in
the calling source (as required to obtain the true benefits of
object-based programming), IDLWAVE considers all available
methods in all classes as possible method name completions. The
combined list of keywords of the current method in all
known classes which contain that method will be considered for
keyword completion. In the *Completions* buffer, the
matching classes will be shown next to each item (see option
idlwave-completion-show-classes). As a special case,
the class of an object called ‘self’ is
always taken to be the class of the current routine, when in an
IDLWAVE buffer. All inherits classes are considered as
well.
You can also call idlwave-complete with a prefix
arg: C-u M-TAB. IDLWAVE will
then prompt you for the class in order to narrow down the number
of possible completions. The variable
idlwave-query-class can be configured to make such
prompting the default for all methods (not recommended), or
selectively for very common methods for which the number of
completing keywords would be too large (e.g.,
Init,SetProperty,GetProperty).
After you have specified the class for a particular statement
(e.g., when completing the method), IDLWAVE can remember it for
the rest of the editing session. Subsequent completions in the
same statement (e.g., keywords) can then reuse this class
information. This works by placing a text property on the method
invocation operator ‘->’, after which
the operator will be shown in a different face (bold by default).
The variable idlwave-store-inquired-class can be
used to turn it off or on.
1)Non-nil means show up to that many classes in
*Completions* buffer when completing object
methods and keywords.
t)Non-nil means fontify the classes in
completions buffer.
nil)Association list governing query for object classes during completion.
t)Non-nil means store class of a method call as
text property on ‘->’.
