[70_11] AST Syntax Highlighting for C++

XmacsLabs:branch-1.2 ← XmacsLabs:unb/70_2/ast_highlight

opened 04:54AM - 07 Aug 24 UTC

## What Use xmake to import tree-sitter and tree-sitter-cpp. Implement a highl…ighting system using tree-sitter, supporting AST syntax highlighting for C++. Specific advantages include cross-line string highlighting, recognition of escape sequences within strings, colorful bracket matching and so on. - cpp-ast-lang.scm : Records the highlighting colors for keywords and different token types. - lang_parser.h & lang_parser.cpp : Programming language parser; uses tree-sitter to compile code and obtain an AST, and then retrieves a series of tokens and their corresponding attributes from the AST. - ast_language.cpp : Performs compilation operations using ``advance`` and obtains the color for corresponding tokens using ``get_color``. ## Why The old lexical highlighting could not distinguish many highlighting situations. <img width="505" alt="Compare" src="https://github.com/user-attachments/assets/2eabbbd1-f48b-4179-9d0b-acad4787af90"> ## How to test your changes? 1. Build and run. 2. Turn on"Edit" -> "Preference" -> "Other" -> "AST syntax highlighting". 3. New cpp code blocks and code lines will use AST syntax highlighting. 4. AST syntax highlighting can be turned off at any time.

这是今年的开源之夏项目，我们正在集成 tree-sitter，目前是用 tree-sitter实现代码高亮
