Question

我尝试根据令牌突出显示文本。代码可以通过以下代码突出显示，但有一些不需要的结果。一些例子：

假设，我打字：

#!/usr/bin/env python3 # -*- coding: utf-8 -*- from pygments import lex from pygments.token import Token from pygments.lexers import Python3Lexer try: import Tkinter as tk except ImportError: import tkinter as tk ROOT = tk.Tk() TEXT = tk.Text(master=ROOT, fg="white", bg="black", font="TkDefaultFont 10") TEXT.pack(fill="both", expand=True) def tag(event): def colorize(word, color): index = [] index1 = TEXT.search(word, "1.0", "end") while index1: index2 = ".".join([index1.split(".")[0], str(int(index1.split(".")[1]) + len(word))]) index.append((index1, index2)) index1 = TEXT.search(word, index2, "end") for i, j in index: TEXT.tag_add(word, i, j) TEXT.tag_configure(word, foreground=color) for token, content in lex(TEXT.get("1.0", "end"), Python3Lexer()): if token == Token.Literal.Number.Integer: colorize(content, color="purple") elif token == Token.Keyword: colorize(content, color="orange") elif token == Token.Operator.Word: colorize(content, color="red") elif token == Token.Name.Builtin: colorize(content, color="blue") elif token == Token.Comment.Hashbang or token == Token.Comment.Single: colorize(content, color="grey") elif token == Token.Keyword.Namespace: colorize(content, color="yellow") elif token == Token.Namespace: colorize(content, color="green") elif token == Token.Punctuation: colorize(content, color="brown") elif token == Token.Literal.String.Double: colorize(content, color="cyan") elif token == Token.Name: colorize(content, color="white") TEXT.bind("<KeyRelease>", tag) ROOT.mainloop()

尽管第一个'a'是 Token.Name ，但是第二个'a'是 Token.Literal.String.Double <，两个a都以相同的颜色突出显示/ p>

另一个不需要的情况是，当我键入“if”时，单词会突出显示，如果我继续在单词“if”中添加一些字母，则单词的颜色会按预期更改。但是，当我删除该单词的某些字母，直到该单词再次成为“if”时，此单词不会像以前那样突出显示。

你能帮我理解这个问题吗？

问题通过以下代码解决。
