Intro

ATSynEdit has adapter for lexers from SynWrite editor. It's EControl lexer engine. Use these:

  • units from https://github.com/Alexey-T/EControl
  • unit from ATSynEdit: ATSynEdit_Adapter_EControl which contains class TATAdapterEControl. You must create object of this class and assign this object to editor property AdapterHilite.

For ex, if you have editor object:

  //form's OnCreate
  Adapter:= TATAdapterEControl.Create(Self);
  Edit1.AdapterHilite:= Adapter;

For ex, if you have 2 editor objects with the same text-source (see help topic ATSynEdit):

  Adapter:= TATAdapterEControl.Create(Self);
  Adapter.AddEditor(Ed1);
  Adapter.AddEditor(Ed2);
  Ed1.AdapterHilite:= Adapter;
  Ed2.AdapterHilite:= Adapter;

Properties

  • Lexer: TecSyntAnalyzer. You must set this prop from SyntaxManager object. SyntaxManager is a collection of lexers, which is loaded from .lxl file. After you load SyntaxManager, get its any item and assign it to Lexer prop. Example exists in demo of ATSynEdit.
  • DynamicHiliteEnabled: boolean. This enables dynamic highlight, ie highlight of tokens depending on caret position. If enabled, adapter reads editor's caret-pos-changed event and recalculates hiliting if needed. Some lexers use this feature, e.g. HTML and Pascal use it: HTML hilites tags with green if caret is inside tag; Pascal hilites "begin"/"end" with green, if caret is inside block, rare C-based lexers hilite brackets.
