TextControlBox-UWP

🤔 What is TextControlBox?

A UWP based textbox with syntaxhighlighting and support for very large amount of text which is still in development.

Reason why I built it

UWP has a default Textbox and a RichTextBox. Both of them are very slow in rendering multiple thousand lines. The selection works also very slow. So I decided to create my own version of a Textbox.

Create custom syntaxhighlighting languages with json:

{
  "Highlights": [
    {
      "CodeStyle": { //optional delete when not used
        "Bold": true, 
        "Underlined": true, 
        "Italic": true
      },
      "Pattern": "REGEX PATTERN",
      "ColorDark": "#ffffff", //color in dark theme
      "ColorLight": "#000000" //color in light theme
    },
  ],
  "Name": "NAME",
  "Filter": "EXTENSION1|EXTENSION2", //.cpp|.c
  "Description": "DESCRIPTION",
  "Author": "AUTHOR"
}  

To bind it to the textbox you can use one of these ways:

TextControlBox textbox = new TextControlBox();

//Use a builtin language -> see list a bit higher
//Language identifiers are case intensitive
textbox.CodeLanguage = TextControlBox.GetCodeLanguageFromId("CSharp");

//Use a custom language:
var result = TextControlBox.GetCodeLanguageFromJson("JSON DATA");
if(result.Succeed)
     textbox.CodeLanguage = result.CodeLanguage; 

Create custom designs in C#:

textbox.Design = new TextControlBoxDesign(
    new SolidColorBrush(Color.FromArgb(255, 30, 30, 30)), //Background brush
    Color.FromArgb(255, 255, 255, 255), //Text color
    Color.FromArgb(100, 0, 100, 255), //Selection color
    Color.FromArgb(255, 255, 255, 255), //Cursor color
    Color.FromArgb(50, 100, 100, 100), //Linehighlighter color
    Color.FromArgb(255, 100, 100, 100), //Linenumber color
    Color.FromArgb(0, 0, 0, 0), //Linenumber background
    Color.FromArgb(100,255,150,0) //Search highlight color
    );
