Syntax Highlighting in RichEdit element

[kashamalasha]

Hi everybody.

Could you tell me is there any UDF that can help to highlight syntax in the _GUICtrlRichEdit element on the fly?

Is it possible to implement this feature in script in simple way using some UDF or something, instead of writing thousand of strings manually?

Thanks in advance.

It was discused here on the forum few times for Au3 Syntax.
For what Language you need it ?

ZPLII https://en.wikipedia.org/wiki/Zebra_(programming_language)

and CPCL (Comtec Printer Control Language ) the both are page description language.

I've tried your UDF, and it is not exact what I want.

I want to implemnt syntax highlighting for the text on the fly. That means it should work like syntax highlighting in Notepad++ or like in Sublime Text editors. The user shouldn't push any button to highlight text in the editor.

Thanks.

UPD: I found some script that works very similar with my requirements. But it can't react when I edit some text that has been already written. Could you help me fix it?

Thanks.

Hey there

 

I wanted to bump this thread to the top because that's exactly what i need.

 

A way to highlight syntax "on the fly", meaning that if the person pastes code on it, the RichEdit control will read the text pasted, and change the color for every word matched (In AU3 syntax)

 

Exactly like SciTE, so far i could only do it for last word.

 

I have figured a way to detect every single word in the AU3 functions, so the only thing i need is: Avoid user from pasting formatted text (i.e. from helpfile) - Highlight syntax when user pastes it (i.e. like if i pasted a code in SciTE) - get the line number where the insertion point is at  - And create a line bar for every line in the RichEdit input, that also scrolls with it

 

I know im probably asking for too much, but any help is appreciated

 

Thanks in advance!!

Grammar :c

Could you use scite dll? 

Edit.

I mean implement scite control in your own gui ?

I copied the keywords in scite files for AutoIt highlighting and cleaned them to make an array with fileread, then i just use the array to detect what type of keyword it is and change its color, sadly it doesn't work for pasted text.

 

About the SciTE control, i'd be amazed if someone could get it and put it on a new gui.

It is the Scintilla control in file scilexer.dll, not SciTE, and It has been done a few times already and a prime example is:

Thanks Jos,

 

Then, how i could make Scintilla control detect language and highlight the syntax?

Just asking this question means you have no idea yet how the Scilexer works.   
There is a lot documented on all the calls you can do so guess you need to start there when you are really interested, but be prepared to take that steep learning curve!

Maybe this is a nice one to start with: 

.. but you will soon see that building an editor like SciTE takes effort.

Hmmm before spending hours brainstorming, I'd try first with a standard RichEdit control, using SetEventMask, WM_NOTIFY, EN_CHANGE and so on
