Cabal Repl
Cabal Repl is a command-line tool that launches an interactive REPL (Read-Eval-Print Loop) environment for Haskell projects managed with the Cabal build system. It allows developers to load project modules, dependencies, and configurations directly into GHCi (the Glasgow Haskell Compiler interactive environment) for testing, debugging, and exploratory programming. This tool integrates seamlessly with Cabal's project structure, enabling quick iteration without manual setup of the Haskell environment.
Developers should use Cabal Repl when working on Haskell projects that use Cabal for dependency management and building, as it provides a convenient way to interactively test code snippets, inspect types, and debug functions within the context of the entire project. It is particularly useful during development phases for rapid prototyping, verifying module imports, and experimenting with library APIs without needing to compile the entire project repeatedly.
