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
