Introducing Igniter for Code Generation and Project Patching

Igniter is a framework designed to aid in code generation and project patching for Elixir developers. Developed by Zach Daniel, Igniter provides a set of tools for library authors to create smarter generators that can semantically modify existing files. For developers, Igniter simplifies the installation of libraries through the command `mix igniter.install <package>`, which automatically adds the package to the `mix.exs` file and runs any provided installer. The framework emphasizes composability, allowing mix tasks built with Igniter to be called individually or composed together to create customized generators. Installation involves adding Igniter to the dependencies and optionally installing the `igniter_new` archive for generating new projects with preinstalled tools.
