Convenient Regex

If you master regular expressions (regex), you can do most of the things without tools. Regex is a technology that allows text search under various conditions.

By the way, this tool also uses regex in the program. For example, “Delete blank lines” is a delete the character that matches the regex ^\s*?$(\r\n|\r|\n)?. This symbol is called a metacharacter and has an abstract meaning. Regex is searching by combining these metacharacters.

Metacharacter	Meaning
`^`	Beginning of line
`\s*?`	0 to n whitespace
`$`	End of line
`(\r\n\\|\r\\|\n)?`	0 to 1 line feed

I also wrote an article on regex, so please have a look if you like.
