Re: [Dltk-dev] Code Assist in DLTK
|
Hi Sebastian,
For proposal colors:
Please check your preference initializer class.
It should call for
org.eclipse.dltk.ui.PreferenceConstants.PreferenceConstants.initializeDefaultValues(store);
to initialize default DLTK values for your language.
Please refer
to:org.eclipse.dltk.examples.python.internal.ExamplePythonUIPreferenceInitializer
as example.
Intelligent content assist:
It very depend on language. For most languages it is very natural to use
AST to understand proposals.
So problem of getting correct AST, then code are not complete is quite
usual.
ANTLR support error recovery, so it is possible to make some kind of AST
in situation with errors:
Some clues are here:
http://www.antlr.org/wiki/display/ANTLR3/Error+reporting+and+recovery
http://www.antlr.org/wiki/display/ANTLR3/Custom+Syntax+Error+Recovery
In our experience we moved to custom hand made parsers:
- It easier to make it fully recoverable as we want.
- Handmade parsers a little bit faster and easy maintainable.
Best regards,
Andrei Sobolev.

hello,
i implemented the example code assist that is given in the tutorial.
So far, it acts as expected, except one thing:
The background of the proposal window is black. Since the color of the
text is also black, you can't read unselected proposals. How can i fix
this?
also one important question:
How can i implement an intelligent content assist system, which
provides proposals dependent on the position in the text?
I looked into some example codes from the ruby and python plugins. It
seems that they are using the AST to determine which proposals have to
be used. But: Most of the time, the AST is not complete while editing
a file, so this can't be the answer (if it is, please tell me how i
cope with incomplete ASTs). I use ANTLR as parser-generator. Is there
tutorial available on how to implement a code completion system using ANTLR?
I would be grateful for some links to tutorials on that subject in
general as well.
thanks in advance,
