bug#32709: Clojure doesn't provide "clojure" executable

Hi Folks,

When I install the "clojure" package, I can't seem to just run `clojure`
and get an interpreter like I would on Debian.

My Java is a bit rusty, but I found I could get it going by installing the "icedtea" package and running:

  java -cp ~/.guix-profile/share/java/clojure-1.9.0.jar clojure.main

or

  java -jar ~/.guix-profile/share/java/clojure-1.9.0.jar

which is a bit of a mouthful.

Regards,
Ben

It is, but this is what upstream tells us to run after building the
package.  Neither pom.xml (for Maven) nor build.xml (for Ant) contain
targets that generate a shell wrapper.

It looks like adding a shell wrapper is a decision that was taken by
Debian and is not what upstream does.  So this is not due to a defect in
the ant-build-system.

To address this we may want to add a wrapper in a custom build phase.

I see what you mean about Debian's approach with the wrapper.

After some investigating I see that Clojure project's current approach
is different again to Debian. Their releases eg.
https://download.clojure.org/install/clojure-tools-1.9.0.XXX.tar.gz
include scripts `clj` and `clojure` which come from
https://github.com/clojure/brew-install. These scripts use functionality
from https://github.com/clojure/tools.deps.alpha/ to automatically
download any libraries you've declared a dependency on at runtime.

There will surely be a script that does this multi-repository build, but
I haven't found it yet.

Regards,
Ben

Alex Miller advised that the build is run by the scripts in the
clojure/brew-install repo. It runs "script/package.sh".

bug#32709: Clojure doesn't provide "clojure" executable

Jesse Gibbons has recently added the "clojure" executable wrapper. This
makes the Guix `clojure` behave similarly to the Debian `clojure`.
Closing this issue.

(Note that this behaviour is still a little different to the bundle
provided by the upstream Clojure project which include custom `clj` and
`clojure` scripts from https://github.com/clojure/brew-install, which
include auto-downloading of dependencies and such.)
