Child Languages and Scopes

SyntaxEditor for Windows Forms Forum

Posted 9 years ago by Joachim Schwieren

I have declared an HTML language and want to use a separate PHP language as child language that is applied when <? ... ?> appears in the HTML code.

I have embedded the child language as follows:
<State Key="ProcessingInstructionState" Filename="PHP.xml" ChildLanguageBackColor="WhiteSmoke">
<!-- Scopes -->
<ExplicitPatternGroup Type="StartScope" TokenKey="ProcessingInstructionStartToken" Style="ProcessingInstructionDelimiterStyle" PatternValue="&lt;?" />
<ExplicitPatternGroup Type="EndScope" TokenKey="ProcessingInstructionEndToken" Style="ProcessingInstructionDelimiterStyle" PatternValue="?&gt;" />    
This works nice but when I have a PHP code snippet that uses the EndScope inside, the language is changed back to HTML. Here is an example:
  echo("Everything is ok here");
  define("xml_field","<?xml version=\"1.0\" encoding=\"utf-8\"?><modules>");
  echo("The line above causes the problem");
When the parser comes to encoding=\"utf-8\"?> it assumes that the child language ends here but this is not the case since the ?> is inside a string scope of the PHP language.

How can I get this working?

Thanks and best regards,

Hi Joe,

Take a look at the documentation under "SyntaxEditor Dynamic Language XML Definition Specification / Scope Tag". You'd probably want to set AncestorEndScopeCheckEnabled to false.
