Stack Repl
Stack Repl is an interactive command-line tool for the Haskell programming language, provided by the Stack build system. It allows developers to load Haskell modules, evaluate expressions, and test code snippets in a REPL (Read-Eval-Print Loop) environment with project-specific dependencies managed by Stack. This tool integrates seamlessly with Stack's project configuration to ensure consistent package versions and avoid dependency conflicts during development.
Developers should use Stack Repl when working on Haskell projects with Stack to quickly test functions, debug code, or explore libraries without compiling entire projects. It is particularly useful for iterative development, learning Haskell syntax, and verifying behavior in a controlled environment that mirrors the project's dependency setup. This helps catch errors early and streamline the development workflow in Haskell applications.
