Parser uses Semantic Versioning. Additionally, Parser employs a script to extract information from VCS (git) log and form a Changelog file. Thus, each commit which affects the public API in any way must be marked with one of the following sigils, or characters at the beginning of line:
-for bugfixes. For example:- lexer.rl: fixed lexing of "alias $foo $bar".+for features. For example:+ Implemented Parser::Rewriter, a module for non-intrusive rewriting of source code.*for miscellaneous changes. For example:* Converted measurement units from metric to imperial.
These categories map nicely to semantic versioning: - bugfixes increment patchlevel, + features increment minor version, * API changes increment major version.
