URL infos

A powerful regex (fewest steps possible) which gives you all the information about urls.

More powerful than python style, this supports things like `"""" """"`, which matches totally. Also supports `"""a""""""b"""`, where there are two matches: `"""a"""`,`"""b"""`.

Returns key/value pair of a url. Also works with google fonts which has additional information

Strip Email ID from Name

Use this regex to select all characters up to the "<" bracket. Then, reverse the direction of the bracket to select the closing ">" bracket. It works across multiple lines. You can get an email list with only the IDs. This is the pattern it matches: Alpha Person <[email protected]> Step 1 (.*) [$<$] gives you [email protected]> Step 2 [$.$] (.*) gives you [email protected]

Date extractor

Substitutes a group of dates by its information and captures the date information. Also allows fooled dates. (2015-02-30, 2015-03-32 for example)
