I am trying to add a lexer defined in a cpp.lcf file to ATsynedit.

On a wiki page it says that TATAdapterEControl can be added to a ATsynedit.:
Adapter:= TATAdapterEControl.Create(Self);
ed.AdapterForHilite:= Adapter;

However, I assume that I have to load the definition of the highlighter. However, the method "Adapter.Lexer.LoadFromFile" cannot load *.lcf files.

I tried to follow the CudaText code:

an:=TecSyntAnalyzer.Create(self);
an.LoadFromFile('../lex/cpp.lcf');

This works but I have trouble finding a simple way to assign this "an" object to a ATsynedit. The CudaText code is more complex and works for multiple lexers, but I am looking for something simple and currently I only need one lexer.

btw. lex.lib.demo on Linux Mint 19.2 did not work for me. It fails to compile "F.edSample.Gutter[F.edSample.GutterBandBm].Visible:= false; " on line 229 in unit formlexerprop. Another issue I have is that most of the packages does not appear on the component palette. Nevertheless, CudaText compiles and works fine.

Thanks,

Rune

demo_econtrol_lexer_lib is now fixed. thanks for report, my mistake.

AFAIR, you cannot load only one .lcf file without using LexerManager TecLexerList. use LexerManager (create new one) and load .lcf files into it.
then assign LexerManager-s items to your ATSynEdit adapter.

example loads lexermanager AppManager. example from CudaText.
file formmain.pas
function procedure TfmMain.DoOps_LoadLexerLib

Code: Select all

    for i:= 0 to ListFiles.Count-1 do
    begin
      an:= AppManager.AddLexer;
      //an.Name:= '_lx_'+LexerFilenameToComponentName(ListFiles[i]);
      an.LoadFromFile(ListFiles[i]);

      //load *.cuda-lexops
      fn_ops:= GetAppLexerOpsFilename(an.LexerName);
      if FileExistsUTF8(fn_ops) then
        DoLoadLexerStylesFromFile_JsonLexerOps(an, fn_ops, UiOps.LexerThemes);
    end;

Excellent, I got it working but I needed to import some units from CudaText that I guess ideally should be part of the components.

Thanks also for making ATsynedit available and for fixing demo_econtrol_lexer_lib.

best,

what units of CudaText should be part of the component? it is separate project.

I am not sure if it is good idea but it would be nice if one could just specify a lexer directory for ATSynEdit and then the lexers auto load. However, now where I know how it works it is not a big deal to use the component as it is.

Thanks,

Rune

We cannot just set the directory. we must find all .lcf files in directory, then add files one by one to the LexerManager, then-- correct inter-lexer links. (using files *.cuda-lexmap).
