Problems with Syntax Colouring - Lexems not working as expected

[Mark Marshall]

I've created a custom config and it is only partially working,  I've tried a number of combinations but with no luck. 

Examples of issues:

Keywords

<lexem BeginBlock="Feature\:" Type="SectionKeyWord" IsBeginRegex="true"  Priority="1" />

<lexem BeginBlock="Scenario:" Type="SectionKeyWord" Priority="1" />

Expected it to highlight Feature: or Scenario: but does not work.

Variables

<lexem BeginBlock="\&lt;[0-9A-Za-z]+\&gt;" IsBeginRegex="true" Type="Variable" />

Should identify strings such as <Eat1> or <Shoe2> but does not.

Tags

 <lexem BeginBlock="(@[0-9A-Za-z]+)" IsBeginRegex="true" Type="TagName" />

Should detect tags like @cat or @text33 but does not.

I suspect I'm doing something silly. Help!

Hi Mark Marshall, 

Thanks for contacting Syncfusion support. 

We have checked your query about highlighting the text through configuration file in SyntaxEditor. We suggest you to mention the same Regex expression in the Split tag also. So that the expression will be considered as single word. Please refer the below code example, 

     <lexems> 

      <lexem BeginBlock="Feature" EndBlock=":" Type="SectionKeyWord" /> 

      <lexem BeginBlock="Scenario" EndBlock=":" Type="SectionKeyWord" />      

       <lexem BeginBlock="@[0-9A-Za-z]+" IsBeginRegex="true" Type="TagName" />          

      <lexem BeginBlock="&lt;([0-9A-Za-z])+&gt;"  IsBeginRegex="true" Type="Variable" />         

 

     </lexems> 

     <splits> 

      <split IsRegex="true">&lt;([0-9A-Za-z])+&gt;</split>        

      <split IsRegex="true">@[0-9A-Za-z]+</split>          

     </splits> 

  

Also we have prepared sample which tries to meet your requirement. Please get the sample from below location,

Thank you.  Helped a lot.  Is there a definitive list of the elements and attributes?  I noticed some around indent control but I've not seen those in the online documentation.
