+# 0.0.1-API-Parser
+
+Parser for fixing this: https://github.com/Homebrew/brew/issues/5725
+
+## Overview
+
+Homebrew is used to install software (packages). Homebrew uses 'formulae' to determine how a package is installed.
+This project will automatically check which packages have had newer versions released, whether the package has an open PR on homebrew, and display the results.
+
+## High-level Solution
+
+- Fetch latest package version information from [repology.org](https://repology.org/) and store on file system.
+- Fetch Homebrew Formulae information from [HomeBrew Formulae](https://formulae.brew.sh)
+- Compare Current Homebrew Formulae version numbers and those coming from Repology's API and Livecheck.
+- Determine whether package has open PR.
+- Display results.
+
+## Details
+
+- This project can be run automatically at set intervals via GitHub Actions.
+- Executing `ruby printPackageUpdates.rb` from the command line will query
+  both the Repology and Homebrew APIs. Homebrew's current version of each
+  package will be compared to the latest version of the package, per Repology's response.
+- Homebrew's livecheck is also queried for each package, and that data is parsed, if available.
+- Checks whether there is open PR for package.
+- Each outdated package will be displayed to the console like so:
+- Note that some packages will not be included in the Livecheck response.  Those will have a 'Livecheck latest:' value of 'Not found'.
+
+```
+Package: openclonk
+Brew current: 7.0
+Repology latest: 8.1
+Livecheck latest: 8.1
+Has Open PR?: true
+
+Package: openjdk
+Brew current: 13.0.2+8
+Repology latest: 15.0.0.0~14
+Livecheck latest: Not found.
+Has Open PR?: false
+
+Package: opentsdb
+Brew current: 2.3.1
+Repology latest: 2.4.0
+Livecheck latest: 2.4.0
+Has Open PR?: true
