What is icr?
ICR is an interactive console (REPL) for the Crystal programming language, allowing developers to execute Crystal code in real-time from the command line. It enables quick testing of code snippets, experimentation with language features, and integration with local project files, similar to how IRB works for Ruby. The tool generates and runs new Crystal programs with each input, providing immediate feedback on output and return values.
Crystal developers who need a REPL for rapid prototyping, debugging, or learning the language, especially those familiar with Ruby's IRB workflow.
ICR offers a seamless, IRB-like interactive experience specifically for Crystal, with features like local file requiring, special commands for debugging, and editor integrations, making it the go-to REPL for the Crystal ecosystem.
