Writing Kotlin Compiler Plugins with Arrow Meta
summary
Arrow Meta provides a functional API that hooks into parsing (AST), analysis (type checking), and IR phases to build real compiler and IDE plugins. Examples show a Hello World plugin that injects a greeting at parse time, a debug-log annotation transformer that wraps a function to log arguments and runtime (example run shows ~36 ms), and a meta testing module used with compilerTest and assertThis to verify generated code. It also supports generating files via transform.newSources and IDE icons via line marker provider.
