Get path (windows style) from any type of text (error message, e-mail corps ...), quoted or not. THIS IS THE SINGLE LINE VERSION ! If you want understand how it work or edit it, go https://regex101.com/r/7o2fyy Relative path are not supported The goal is to catch what "Look like" a path. See the limitations UNC path and prefix path like //./], [//?/] or [//./UNC/] are allowed some url path like [file:///C:/] or [file://] are allowed Catch path quoted with ["] and [']. But these quotes are include with the catch Quoted path is not concerned by limitations Limitations : (only unquoted path) [dot] and [space] is allowed, but not in a row [dot+space] or [space+dot at end of file name isn't catched INSIDE A NAME FILE (or last directory if it is a path to a directory) : [comma] is not supported (it stop the catch) after a first [dot], any [space] stop the catch after a [space], catch is stoped if next character is not a [letter], [digit] or [-] so, double [space] stop the catch Compatibility compatible PCRE, PCRE2 AutoHotkey : don't forget to escape "%" in "`%" /!\ Powershell and .Net /!\\ : this regex need some modification to be interpreted by powershell. You have to replace each (?&CapturGroupName) by \k. Use this powershell code to do this replacement : ` $powershellRegex = @' [Put here the regex to replace (?&CapturGroupName) with \k] '@ -replace '\(\?&(\w+)\)', '\k' ` This example code must return : [Put here the regex to replace \k with \k]

Description

This RegEx can be used to check whether a string (usually a commit message) matches the structure specified in the conventional commits specification and it allows to retrieve the sections of the structure via. named groups.

The groups are the following: (? means, that this can be empty/nullable)

  • type - The commit type (e.g. feat, fix, etc.)
  • scope? - The optional scope of the commit (e.g. the part of the codebase that the changes affect)
  • breaking? - ! or empty - whether breaking changes where marked using an exclamation mark after the type/scope
  • description - The (short) one-line description of the commit
  • body? - The optional (multiline) long description of the commit
  • footers? - The optional footer(s) of the commit
