I have been using Bower to manage purescript dependencies. This relies on node and Bower to manage the packages. The problem is that there’s not a lot of users using Bower these days, meaning Bower is not well maintained anymore.
The purescript community has been trying to liberate purescript from node and bower. So they have made psc-package.
Download the source, extract, then build with stack build
. After
the compilation, run stack install
. This will install the executable in the
local bin-path. psc-package
is now ready to be used.
To start a project run pulp build
to scaffold the project. This will generate
the Main
directory with the Main.purs
file and Test
directory with the
Test.purs
file. This will also generate bower.json
file. Delete this file
since we will not be using bower anymore. Run psc-package init
to generate
psc-package.json
.
Important sections to note about the psc-package.json
file is the sets
and
depends
field. sets
is the set of packages, and the contents of the set is
based on the version. So if the package we’re trying to install is missing check
the version we may not have the right version. To check which package is
included in the list go to package-sets. I believe package-sets are
packages blessed by the community.
To install packages run psc-package install <package-name>
or put the package
name in the depends
section of psc-package.json
and run psc-package build
.
