The most common way to install the latest version of Idris and its packages is through pack
Idris' package manager. Working with the latest version of Idris is as easy as pack switch latest
.
Follow instructions on the pack
repository for how to install pack
.
To use pack
and idris, you will need an .ipkg
file (Idris-package file) that describes your idris project.
You can generate one with idris2 --init
. Once setup with an .ipkg
file, pack
gives you access to the pack collection of packages, a set of compatible libraries in the ecosystem.
If your dependency is in the depends
field of your .ipkg
file, pack
will automatically pull the dependency from you matching pack collection.
The wiki hosts a list of curated packages by the community.
Finally, pack
also makes it easy to download, and keep updated version of, idris2-lsp, and other idris-related programs.
