Is there anyway to add an aditional binary that can be used at compile time. about heroku-buildpack-elixir HOT 3 CLOSED

@CrowdHailer I think it should be possible to get the hook working. My guess is that $PATH is substituted into the string at the wrong time. Specifically, it happens here
https://github.com/HashNuke/heroku-buildpack-elixir/blob/master/lib/misc_funcs.sh#L34

When really, you probably want it to happen here

I haven't looked into how to get that to happen, but I suspect there are multiple ways of doing this.

Another possibility is to look at the way the phoenix static buildpack depends on this buildpack. It essentially requires that you use multiple buildpacks and that this buildpack is executed before the phoenix static one. This buildpack installs elixir and erlang and updated the PATH, for example, see

I wonder if something similar can be done with gleam.

I'm not actually using this approach anymore, I ended up with a Docker solution. However I suspect there is still interest in this approach from Gleam folks in general. Might be interesting to see if anyone in the discord channel is interested

If there is anyone interested, I'm looking at this approach again.
I've tried making a build pack that installs only the gleam binary.
Most of the work is here but I haven't yet figured how to update the PATH so it persistes to separate build steps.
