- 从'ANSI_FMT'宏中移除ANSI转义码,以适应不支持颜色的终端。 - 现在可以通过定义'ANSI_FMT_DISABLE'宏来禁用ANSI转义码。 refactor(gen-expr): 改进代码格式和临时文件处理 - 在gen-expr.c中进行了代码格式调整,以保持一致的风格。 - 优化了临时文件的处理方式,确保路径和命令在不同操作系统上的兼容性。 refactor(main): 调整打印格式和字符串分割逻辑 - 修正了main.c中的打印格式化字符串,以适应不同编译器的规范。 - 改进了命令帮助功能的字符串分割逻辑,以正确处理子命令查询。 update(README): 添加编译和运行说明,禁用ANSI转义码说明 - 在README.md中添加了关于项目编译和运行的说明,包括C++11标准的要求。 - 提供了关于在不支持ANSI转义码的终端上禁用它的说明。 fix(.gitignore): 忽略所有文件但特定文件除外 - 修正了'.gitignore'文件,以忽略所有文件,但'.gitignore'、'.c'、'.cpp'、'.h'和'.md'文件以及'Makefile'除外。
