Cabalinstall

Cabalinstall is a command-line tool used for installing Haskell packages. It is part of the Haskell toolchain and works with Cabal, the build system and package manager for Haskell. Cabalinstall allows users to easily download, compile, and install libraries and applications written in Haskell from the Hackage repository, the primary package archive for Haskell. The primary function of cabalinstall is to resolve package dependencies, ensuring that all required libraries are available before building and installing the target package. It can install packages globally on a system or locally within a specific project. When installing a package, cabalinstall typically compiles the source code, links it with its dependencies, and makes the executable or library available for use. Users interact with cabalinstall by specifying the name of the package they wish to install. It can also be used to update existing packages. The tool plays a crucial role in managing the Haskell development environment and ensuring reproducibility of projects by managing their dependencies.
