RE: [cdt-dev] C Editor

[Sebastien Marineau <sebastien@xxxxxxx>]

Hi Igor,

 

the main classes to look at for the editor's highlighting and text presentation are

part of the JFace AbstractTextEditor's framework. The text presentation is

done by a variety of classes that implement the partitionning (splitting

source files into regions, e.g. code versus comments) and then

actual scanners for each region that highlight keywords etc.

 

Look in CSourceViewerConfiguration.java as a starting point (org.eclipse.cdt.internal.ui.text)

and follow from there -- CPartitionScanner, CCodeScanner etc. The mechanisms

for the preference changes is also relatively complicated, but eventually

filters back to an InvalidateTextPresentation() call in the CEditor (it

also requires that colors be abstracted from the styles returned by the

keyword scanners).

 

In any case, it will probably take you a few days to understand the framework, but once

you do, you'll see that it has a lot of features built in. As Thomas suggested, you may

also want to ask questions in the jface mailing list if we don't know the answer.

 

Sebastien
