a) Is it possible to draw a timestamp instead of the line number in front of the lines? b) Does the control / schema support regex? c) Is it possible to modify the schema at runtime? d) Is it possible to set the background color for the lines? Thanks Andre ------------- Codejock support |

It seems to me that the SyntaxEdit control is the poor stepchild. ------------- Codejock support |

it's a difficult problem:
deciding on a structure that can be used to describe any programming language. Then coming up with a syntax to describe that structure, and a parser to decode schema files. I can imagine there are lots of headaches with the initial structure. For instance some languages are not easily described using such a structure (Lua for one).

I disagree. Scintilla solves this elegantly using tokenizers which give you full control of the coloring. Sometimes complicated, but still a robust solution.
I'm not going to use the SyntaxEdit until this is implemented.
PS. Funny you mention those functions. I needed the exact same things some months ago. I sense you're developing my application ;)

| scintilla uses C++ code to implement tokenising and structural analysis of each language. They didn't try to create a meta language for all of this, they just have plugins to do it. It is very effective, but it's totally different than trying to create a global syntax for a schema definition and only one parser for all languages. |

That's true, but why not extend SyntaxEdit to allow for this approach too?
syntaxEdit.EnableTokenizer(TRUE);
CMySyntaxEdit::OnColorize(params) {...}

| sure, I've got nothing against the plugin approach. |

Please try current version of SyntaxControl - in Static app which Give me some feedback about the speed of current version. Be also sure that YOU HAVE PROPER SYNTAX File - e.g. attach it to your post note so I can also try it ------------- Mark Doubson, Ph.D. |

Just tried it with XTToolkitPro.h and the C++ schema from 12.1.1: - Scrolling is pretty slow - Text selection is horribly slow - Editing is slow Bug: Window > Split, text selection no longer possible Bottom line: SyntaxEdit is not useable for anything in its current state. Also you haven't answered any of my initial questions. I'm waiting over A YEAR for a reply!!! ------------- Codejock support |

Thanks for your reply. I repeat your steps in same static app and using SciTE. Timing very similar. I like to use some benchmarks instead of emotional terms.
Btw - window -> split is not for current test case (almost disable).
I am sorry about your questions - your asked another persons in the past. I see the use of CJ SyntaxEdit in the current architecture. ------------- Mark Doubson, Ph.D. |

Quite simple, put some test files together and then figure out the FPS. How long does it take to draw the view at the same size/lines? And just because someone else isn't better it doesn't mean you're good! SyntaxEdit is too slow and not flexible enough. ------------- Codejock support |

Regarding text selection: Scintilla is several magnitudes faster, period. At least this is true for SyntaxEdit 12. ------------- PokerMemento - http://www.pokermemento.com/ |

Did you try the updated exe Mark posted? As far as speed, what files are you guys opening? For example I can open XTPSyntaxEditCtrl.cpp (one of the largest files in the toolkit) and editing\text selection seems OK. Using Mark's exe can you test that file and give us the results? |

>> Is it possible to modify the schema at runtime?
Yes you can do it. We have architecture to use only memory-located syntax and color schemes - so you can modify it on fly ------------- Mark Doubson, Ph.D. |

in my tests speed was not a factor of the source file you look at, but was a factor of the complexity of the schema file.
I tried many times to get a lua parser going which would allow outlining. I'd make small(?) changes in the schema file, and there would be a huge variation in the runtime speed to parse the same simple lua file (it was a single function if I remember correctly).
I think I suggested it before, but have you considered the gold parser approach?

Then your schema file would be in BNF (a standard, and many existing BNF specs for popular languages). Then just assign colours etc to BNF productions. ------------- http://www.wingate.com - http://www.wingate.com |

I also found that old CJ VB syntax not properly supported different case of outlinening (collapsed blocks) but I improved it recently and publish somewhere in Forum (may be in ActiveX zone?). It now supported recursive and non recursive collapsed blocks (e.g. for "Region ----- "End region" vs "Private Sub ---- End Sub") ------------- Mark Doubson, Ph.D. |

Mr http://forum.codejock.com/member_profile.asp?PF=1755&FID=132 - ABuenger I am ready to use your help to improve our SyntaxEdit in the direction you describe as promisable - add Assembler support with extra columns to visual data such as timestamps, hex data display and so on
but need some real input from your side - not just critics and ref on SciTE.
If you ready - open the Issue for SyntaxEdit modification steps and we can work together ------------- Mark Doubson, Ph.D. |

Hi Mark, please try to add line modification markers to the control if possible ...  Thanks a lot |
