Re: [Dltk-dev] Unusual problem with PresentationReconciler; help please
|
what type of IPresentationReconciler implementation are you returning from your ScriptSourceViewerConfiguration subclass?

Sorry for being too brief.
I have a very basic editor-only project (extending TextEditor) that I am
attempting to port to DLTK to pick up greater functionality. The
basic editor has partitioning, pair matching, rule and non-rule based
repairers working. No outline or AST. I started a new DLTK
project(s) following the form of the Python sub-project initially and Lua
subsequent. I created an Antlr based grammar/core and have adjusted
the dependencies of my old editor to depend from ScriptEditor, etc, again
following the form of Python and Lua. I have left out things like
search and debug, looking to get basic functionality first. Most
problems I could trace out fairly easily -- recognizing the difference
between
IDLTKLanguageToolkit and
IDLTKUILanguageToolkit and
fixing the plugin.xml/Extensions was a tricky.
But, the current error is giving me no hint as to the source of the
problem. I know the logic of my PresentationReconciler is correct
and the dependencies have been changed to match those in
Python/Lua. Obviously I am missing something -- just not sure
what.
Given the error, hoping someone might have an opinion as to the likely
source of the problem.
Thanks,
Gerald

your question. are you implementing a new plugin, or are you trying to
the plugins listed below and you're getting that error?
