| Re: [cdt-dev] How to add Keyword to CDT Parser |
|
To highlight new keywords in the editor I called the "addKeyword" function in the constructor of my ScannerExtensionConfiguration like this:
addKeyword("myKeyword".toCharArray(), IGCCToken.tIDENTIFIER ); You can find an example implementation in GCCScannerExtensionConfiguration. I implemented my own ScannerExtensionConfiguration based on this, extending AbstractScannerExtensionConfiguration. best regards, Sebastian > Date: Sun, 9 Mar 2014 23:14:44 -0700 > From: y_anitha@xxxxxxxxx > To: cdt-dev@xxxxxxxxxxx > Subject: [cdt-dev] How to add Keyword to CDT Parser > > I have to extend CDT Parser to recognize some new Keywords and understand > them.
