Generate regexs. More information: https://github.com/pemistahl/grex.

• Generate a simple regex:

grex {{string1 string2 ...}}

• Generate a case-insensitive regex:

grex {{[-i|--ignore-case]}} {{string1 string2 ...}}

• Replace digits with \d:

grex {{[-d|--digits]}} {{string1 string2 ...}}

• Replace Unicode word character with \w:

grex {{[-w|--words]}} {{string1 string2 ...}}

• Replace spaces with \s:

grex {{[-s|--spaces]}} {{string1 string2 ...}}

• Detect repeating patterns in the input and shorten them using {min,max} quantifiers:

grex {{[-r|--repetitions]}} {{string1 string2 ...}}

• Generate regex of test cases (separated by newline) from a file:

grex {{[-f|--file]}} {{path/to/file}}

• Do not generate anchors and non-capture groups:

grex --no-anchors {{[-g|--capture-groups]}} {{string1 string2 ...}}
