We can customize the color of line if it is end with specific character. It can be achieved by setting the lexem in custom config file.


Lexem: It contains rules for parsing the text. There are two attributes to specify the format of the lexem.


  • Type: Type is used for standard predefined types of the lexems.
  • FormatName: The FormatName is used only when Type is Custom.


Here we have highlighted the line if end with “!” character. The following code demonstrates the same.


Code Example: [XML]


<!-- Configuaration -->


<ConfigLanguage name="new" CaseInsensitive="true">




<!-- Highlight color -->


<format name="String" Font="Courier New, 13pt, style=Bold" FontColor="Green" />












<!-- Set the Required Highlight format -->


<lexem BeginBlock="[A-z\s]+\!" IsBeginRegex="true"  Type="String"/>






<split IsRegex="true">[A-z\s]+\!</split>







Code Example: [C#]
