Retrieve Keywords in Language - SyntaxEditor for WPF Forum

Posted 15 years ago by cowcow

In the Sql.langdef, I have the following ExplicitPatternGroup where TokenKey="Keyword"

<ExplicitPatternGroup TokenKey="Keyword" ClassificationTypeKey="SqlKeyword" LookAheadPattern="{NonWord}|\z">
<ExplicitPatterns><![CDATA[
ADD ALTER AS ASC AUTHORIZATION BACKUP BEGIN BREAK BROWSE BULK BY CASCADE CHECK CHECKPOINT CLOSE SELECT
]]></ExplicitPatterns>
</ExplicitPatternGroup>

I have initialize the language to the SyntaxEditor.

Using stream As Stream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream("Sql.langdef")
If stream IsNot Nothing Then
Dim serializer As New SyntaxLanguageDefinitionSerializer()
serializer.InitializeFromStream(language, stream)
End If
End Using

Is it possible to get all the keywords from the object language?

e.g something like this

For each keyword in language.xxxx
......
next keyword

I would expect to get these keywords one by one, e.g: ADD ALTER AS
Is that possible?

Thanks,
Cow

Hello,

What you would need to do is get the DynamicLexer, find the default state, get the appropriate pattern group, and iterate through the pattern group. Here is some example code that might be helpful:


Dim lexer As ILexer = syntaxEditorInstance.Document.Language.GetService(Of ILexer)()
Dim dynamicLexer As DynamicLexer = TryCast(lexer, DynamicLexer)
If dynamicLexer IsNot Nothing Then
 Dim group As DynamicLexicalPatternGroup = dynamicLexer.DefaultLexicalState.LexicalPatternGroups("SqlKeyword")
 For Each pattern As DynamicLexicalPattern In group.Patterns
  ' do something with pattern
 Next pattern
End If

Please let us know if you have further questions.

It works, thanks.

The latest build of this product (v24.1.5) was released 4 days ago, which was after the last post in this thread.
