I have to extend CDT Parser to recognize some new Keywords and understand them. Ex: _c_status
Towards this I have added an extension to org.eclipse.cdt.core.language in the plugin.xml file.
<extension point="org.eclipse.cdt.core.language">
<language
class="com.dev.core.languages.NewCLanguage"
id="c"
name="NEW C">
<contentType
id="org.eclipse.cdt.core.cSource">
</contentType>
<contentType
id="org.eclipse.cdt.core.cHeader">
</contentType>
</language>
<extension>
I have provided an implementation for the class as below:
public class NewCLanguage extends GCCLanguage implements ICLanguageKeywords, ILanguage {
private static final NewCLanguage DEFAULT_INSTANCE = new NewCLanguage();
protected static final NCScannerExtensionConfiguration NC_SCANNER_EXTENSION =
new NCScannerExtensionConfiguration();
public static NewCLanguage getDefault() {
return DEFAULT_INSTANCE;
}
public String getId() {
return "com.dev.core.c";
}
public Object getAdapter(NewCLanguage language) {
return getAdapter(this);
}
@Override
public String[] getKeywords() {
return new String[] {"_c_status"};
}
protected IScannerExtensionConfiguration getScannerExtensionConfiguration() {
return NC_SCANNER_EXTENSION;
}
}
And provided the implementation for the ScannerConfiguration as below:
public class NCScannerExtensionConfiguration extends
GCCScannerExtensionConfiguration {
public static final String CSTATUS = "_c_status";
public static final char[] extendcCSTATUS = "_c_status".toCharArray();
public CharArrayIntMap getAdditionalKeywords() {
CharArrayIntMap additionalCKeywords = new CharArrayIntMap(0, 0);
additionalCKeywords.put( NCScannerExtensionConfiguration.extendcppCCSTATUS, IToken.t_class);
return additionalCKeywords;
}
}
I have also linked the source files to be associated with NewCLanguage in the Language Mappings under Preferences. Yet I don't think the new keywords are being recognized. Is there a way i could check if the keywords are recognized. The keyword is not highlighted in the editor. Should i also extend the editor?
My second part of the query is how to extend the parser to provide the implementation for the keyword. the keyword _c_status is always associated with a function call. It means that the function call with this keyword need to follow a different syntax. Can you please help me with how I could achieve this. I need this on priority basis.
Thanks in advance.
