使用正则表达式批量去重捕获末尾带z的Numeric并前置到代码头部

我为公司制定了一套正则处理流程，近期要优化移除无用信息。现在用Notepad++正则批量编辑程序，目前手动收集末尾带z的Numeric变量放到代码开头，但重复变量会导致编译失败，希望用正则自动捕获这些变量，去重后放到ByteCode下方。

现有查找替换规则 #

• 查找规则：

(Object(?s:(?!Object).)*?ByteCode :)((?s:(?!Object).)*?(?:z =.*|.*z(?:,|\)).*)(?s:.*?)EndObject)

• 替换规则：

\1\nNumeric x, x, x, x, x\nNumeric x, x, x, x, x\2

尝试过的查找替换规则 #

• 查找规则：

(Object(?s:(?!Object).)*?ByteCode :)((?s:(?!Object).)*?.*(?!Numeric \3).*?(?: |\(|^)([a-zA-Z0-9_]*?z)(?s:.*?)EndObject)

• 替换规则：

\1\nNumeric \3\2

解决方案 #

Notepad++原生正则不支持直接完成「捕获+去重+拼接插入」的全流程，分两步操作即可实现需求：

步骤1：提取并去重末尾带z的变量 #

1. 打开目标文件，使用Notepad++的查找所有在当前文档功能，查找规则：

\b([a-zA-Z0-9_]+z)\b(?!\s*:)

• 规则说明：\b匹配单词边界，确保只捕获完整变量名；(?!\s*:)排除ByteCode :这类带冒号的行，避免误匹配

2. 查找完成后，复制所有匹配结果到剪贴板
3. 粘贴到临时文本编辑器，用正则去重：
   • 查找：^(.*)$\s*^\1$（勾选「正则表达式」和「匹配换行符」）
   • 替换：$1，重复点击替换直到无匹配项
4. 将去重后的变量整理成目标格式：要么用逗号分隔成一行Numeric var1, var2，要么每个变量单独一行Numeric var

步骤2：插入到ByteCode下方 #

使用正则替换将整理好的变量插入指定位置：

• 查找规则：

(ByteCode :)\r?\n

• 替换规则（把示例中的变量列表换成你整理好的内容）：

\1\r\nNumeric TempRmCntrlSigz, DamperPositionz\r\n\r\n

进阶：批量处理脚本（可选） #

如果需要处理大量文件，可使用Python脚本自动化完成：

import re
from pathlib import Path

def process_program_file(file_path):
    # 读取文件内容
    content = Path(file_path).read_text(encoding='utf-8')
    
    # 提取所有末尾带z的变量
    vars_with_z = re.findall(r'\b([a-zA-Z0-9_]+z)\b(?!\s*:)', content)
    # 去重并排序
    unique_vars = sorted(list(set(vars_with_z)))
    
    # 生成声明行，每4个变量一行（可根据需求调整数量）
    decl_lines = []
    chunk_size = 4
    for i in range(0, len(unique_vars), chunk_size):
        chunk = unique_vars[i:i+chunk_size]
        decl_lines.append(f"Numeric {', '.join(chunk)}")
    
    # 插入到ByteCode下方
    updated_content = re.sub(
        r'(ByteCode :)\r?\n',
        rf'\1\r\n{"\r\n".join(decl_lines)}\r\n\r\n',
        content
    )
    
    # 保存修改后的文件
    Path(file_path).write_text(updated_content, encoding='utf-8')

# 处理单个文件示例
process_program_file("your_program_file.txt")
