Regex Tester

通过本地 Python 脚本测试和调试正则表达式：支持 --pattern、--text（或 stdin）、--flags（i/m/s）、--json 输出和 --list-patterns 模式库，返回匹配数量与位置、捕获组，并用退出码 0/1/2 表示匹配、无匹配与非法正则。

Examples

# Test a pattern interactively
python scripts/regex_tester.py --pattern "[a-z]+" --text "hello world"

# Use common pattern shorthand
python scripts/regex_tester.py --pattern "email" --text "contact@example.com"

# Case-insensitive match
python scripts/regex_tester.py --pattern "hello" --text "HELLO world" --flags i

# Extract all matches from file
python scripts/regex_tester.py --pattern "\d+" --text "order 123 and 456"

# JSON output for scripting
python scripts/regex_tester.py --pattern "\w+" --text "hello world" --json

Pattern Matching Output Format

Pattern: [a-z]+
Text:    "hello world"

Matches: 2 found
  [0] "hello" (pos 0-5)
  [1] "world" (pos 6-11)

Groups: none

For patterns with capture groups:

Pattern: (\w+)@(\w+)
Text:    "user@domain"

Matches: 1 found
  [0] "user@domain" (pos 0-11)
Groups:
  [1] "user"
