Syntax Highlighting in RichEdit element

5 posts in this topic

#1 ·  Posted

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 ?

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.

      Row Sum (Σ) Formula Validation
      By czardas
      Much work still needs to be done on my current project, but design concepts often benefit more from early criticism. Although there may be nothing particularly innovative about this project, user experience is everything. I would like you to look at the behaviour of the controls on this GUI. Unless you type something really awful, it allows you to finish typing the formula before testing the input. When typing into an edit control, pressing the enter key activates the okay button.
      The program itself, mainly consists of a listview control, which you can't see - just imagine it looks like a stone age version of Excel with a nice paint job, but no bells or whistles. What Row Sum (Σ) is intended to do is loop through all the rows, calculate a sum and print the output in a newly created column. The user is prompted to type a formula into the following GUI. Please try to figure it out, and break it any way you can.
      #include <GUIConstants.au3> #include <GuiEdit.au3> #include <Misc.au3> Global $g_iAvailableCols = 24 ; arbitary dev variable [column count will eventually be read from a listview control] ; missing several thousand lines of code...

      Syntax for embedding @username in tasklist command
      By Jdr
      I'm using this code:
      #include <Constants.au3> Global $DOS, $Message = '' ;; added "= ''" for show only. $DOS = Run(@ComSpec & " /c tasklist /S server1 /U server1\admin /P password /FI " "USERNAME" & "eq" & @UserName /FI ""IMAGENAME eq notep*""", "", @SW_HIDE, $STDERR_CHILD + $STDOUT_CHILD) ProcessWaitClose($DOS) $Message = StdoutRead($DOS) MsgBox(0, "Stdout Read:", $Message) But I can't get the syntax right.  The tasklist command from the commandline goes like this and works: 
      tasklist /S server1 /U server1\admin /P password /FI  "USERNAME eq user1" /FI "IMAGENAME eq notep*".  So everything behind the FI parameter needs quotes. I'm using the @username macro to get the logged on user.  But I just can't get the syntax right.

      AU3 Syntax Highlight for RichEdit - Machine Code Version - Updated 12/25/2013
      By Beege
      Last Update - 12/25/2013
       
      Here are a few functions that will take any Autoit code and convert it to RTF format with AutoIt syntax highlighted.
      The code can be saved or applied right to the RichEdit control you are working with.

      Special thanks go to MrCreator. A good amount of ideas for different parts of the code and regular expressions came from studying his >Autoit Syntax Highlight for HTMLBBCode. Viewing how he handled certain situations was very helpful. Thanks to Robjong also for feedback on some of the SRE expressions.
      Update - 12/25/2013
      Fixed incorrect coloring for INI functions
      Update - 10/29/2013
      Heres my latest version. Its been completly rewritten in assembly and is working very fast. The previous version for this library worked by checking for each catagory (variable, keyword, string, etc) one catagory at a time using reg expressions. The libaray works by walking the data one time adds the coloring each time it hits a catagory. Each time we hit a catogory, we jump to that catagoys procedure and continue processing until that catagory is over, then return to the main loop, or another catagorey. This make processing parts like comments and strings very fast. 
       
      For strings Im passing the data to an autoit function for the send keys. For the UDFs im also passing the data to an auto it function, but only to check if its a function, not modify any data. Using a dictionary, I setup a structure where the key is the function name and the item for that key is the length. Checking to see if a key exists in a dictionary is very fast, so is the lookup so if it is a key, I pass back the length of the funtion, along with the function type (Native, UDF, Keyword). Code for Native functions and Keywords are built into the assembly code, the reason they are also in the udfs is for case insensitve checks. The assembly code then adds the coloring and copys the bytes specifed by the length.
       
      There full assembly code is in the build folder. That includes everything you need compile the full function if you wanted to change it somehow. Theres also a short little brief on assembly code in general and working with strings in assembly.

      RichEdit Hyperlinks (Friendly)
      By InunoTaishou
      I think RichEdit has been my favorite thing I've ever discovered on AutoIt lol. In my quest to add in more html tags to my _StringToRichEditArray I needed a way to do href! There was an example I found that I followed but it didn't format correctly and didn't work 100% but it gave me a good base. Think I'll tackle inserting an image next, not looking forward to that. If anyone has an idea on how to do it let me know.
      Known issues (these will cause the hyperlink to lose the +li attribute after the RichEdit is updated):
      The hyperlink and friendly text are appended/inserted (directly adjacent to a non whitespace) but the hyperlink is not a valid hyperlink. Changing the char color for the control causes the hyperlink to lose it's hyperlink color (the light blue). Fix for Issue 1:
      Use the full URL for the hyperlink (https://www.autoitscript.com/site/ instead of www.autoitscript.com/site) Use any hyperlink with any friendly text that does not have www at the beginning (Hyperlink: www.google.com, Friendly Text: google.com) Use any hyperlink with any, or no, friendly text, but have a whitespace to the left of the hyperlink. Fix for Issue 2:
      I have no fix. Updated RichEdit Hyperlink.au3
