CTkSyntaxHighlightedTextbox

arguments

there currently is only one extra argument: tags
tags can either be a dict or a pathlib.Path pointing to a json file containing said dict
the structure of the dict is the following:

{"tags":[{
    "name":"Example",
    "text_color":"#f00",
    "background":"#000",
    "patterns":["e"]}]
}

"tags" tags is a list that contains any number of dicts called "tags"
a tag has 4 elements:

• "name" unique identifier of the tag
• "text_color" (optional) the color of the tagged text
• "background" (optional) the color of the background of the tagged text
• "patterns" a list of regex patterns. All text that matches one of these patterns wil be tagged. If the pattern contains a capturing group only text in a capturing group will be tagged

methods

replace_tags_dict

load a new tags dict
the argument tags works the same as the tags argument of the main class explained above

highlight

runs the HighlightingEngine
automaticaly called on initialisation and the <<Modified>> and <Key> events

example

import CTkSyntaxHighighlightedTextbox as CTkSyHiText
import customtkinter as ctk

win = ctk.CTk()

textbox = CTkSyHiText.CTkSyntaxHighlightedTextbox(
    master=win,
    tags={
        "tags": [
            {
                "name": "e",
                "text_color": "#080",
                "background": "#ddd",
                "patterns": ["e"],
            },
            {
                "name": "t",
                "text_color": "#f00",
                "patterns": ["t"],
            },
        ]
    },
)

textbox.pack(fill=ctk.BOTH, expand=True)

textbox.insert("1.0", "the e's & t's in this sentence will be highlighted") # textbox.highlight() runs automaticaly

win.mainloop()

the above example doesnt look amazing but thats not the point of the example
here is a image of what it can look like if some proper styling is done:
