Dynamic Regex Badge

⚠️ Experimental: This badge is considered experimental and may change or be removed at any time.

This badge will extract text from a file using re2 (a subset of regex: https://github.com/google/re2). The main use-case is to extract values from unstructured plain-text files. For example: if a file contains a line like version - 2.4 you can extract the value 2.4 by using a search regex of version - (.*) and $1 as replacement.

Query Parameters
url string — REQUIRED The URL to a file to search. The full raw content will be used as the search string. Example: https://raw.githubusercontent.com/badges/shields/refs/heads/master/README.md
search string — REQUIRED A re2 expression that will be used to extract data from the document. Only the first matched text will be returned. Example: Every (.*?) it serves (?<amount>.*?) images
replace string A replacement string that will be used as the replacement of the search regex. Use $$ to escape a $ sign, $n to specify the nth matched group, $<name> for a named group, etc. If empty (default), no replacement will be done and the full matched text will be shown. Example: $<amount>/$1
flags string Flags to be used when creating the regex: i = case-insensitive, m = multi-line mode, s = dot matches linebreaks. None by default. Example: ims
