Codemods and Other Upgrade Automation
Much of the work of major software upgrades can now be automated via “codemods” - software that modifies other software’s source code (source code modification). Here is a collection of such codemods that either have saved us time in previous upgrades or seem likely to do so in future ones. For more context on many of these, see Herding Ponies: Coordinating and Automating Django Upgrades Across 100+ Repositories .
