With the latest iteration of the TTMSFNCMemo we have now added support for multiple sources and a file-extension/language map which is used to select the correct language based on the file-extension when loading a file in the memo. 

Sources

Sources enables the user to quickly switch between different lines, whilst keeping breakpoints, cursor position, …

You can simply add sources to the Sources collection in the form designer or you can use the various add source function's to quickly load a file like the example down below: 

  if OpenDialog1.Execute then
  begin
    source := TMSFNCMemo1.AddSourceFromFile(OpenDialog1.Files[0]);
    tab := TMSFNCTabSet1.AddTab(source.Name);
    TMSFNCMemo1.ActiveSource := tab.Index;
  end;

File-extension / Language mapping

Every time you load a file, the memo will check the LanguageFileExtensionMap collection if it finds a registered extension, and then set the corresponding language. Just add the file extensions you want to the collection and you're good to go. Nothing else is needed.
