-# 任务描述
-改进 `-c` 参数的文本对比输出格式，使其能够：
-1. 显示行号
-2. 显示每行的修改状态符号（+代表只有add，-代表只有delete，@代表既有add又有delete，=代表无修改）
-3. 在分组间添加分隔符（如横线）
-4. 保持现有的颜色功能
-
-当前输出格式：
-```
-4123
-i get 13 history
-i get 24 history
-123
-operations:
-add "4" on [0,0]
-add "3
-i get 1" on [2,2]
-add " history
-i get 2" on [3,3]
-add " history
-123" on [4,4]
-```
-
-期望输出格式：
-```
-+1|4123
-+2|i get 13 history
-+3|i get 24 history
-+4|123

-# 项目概览
-这是一个基于Python的文本版本控制系统，使用 `-c` 参数进行文本对比。项目使用Convention模块进行配置管理和颜色输出。
-
-# 分析
-当前 `compare` 方法在 `app.py` 第151-186行，使用 `levenshtein_distance_with_operations` 函数计算差异。需要：
-1. 修改输出逻辑，将操作转换为按行显示
-2. 为每行添加符号和行号
-3. 添加分组分隔符
-4. 保持颜色功能
