Disappeared from stackage nightlies?

[mstksg]

Hi,

Thank you for the great package :) I was wondering if this package was being specifically withheld from the new stackage nightlies which are running on GHC 8.0? I seem to be able to build this package fine with the latest nightly:

$ git clone git@github.com:ku-fpg/data-reify.git
$ cd data-reify
$ stack init --resolver nightly-2016-06-02
$ stack install

Is it just that package just taken off automatically with the new update, and has not been manually added back on yet? Or is there an intentional reason I'm missing?

Thanks!

The reason is even simpler. Currently, there are no @ku-fpg packages explicitly listed in the build plan for Stackage, but a couple of them were automatically brought in to satisfy the dependencies of other packages (for example, diagrams-canvas brings in blank-canvas and kansas-comet). I suspect a package that depends ondata-reify was blocked from Stackage recently due to the GHC 8 release, leading to data-reify also being dropped.

To prevent this thing in the future, I could explicitly add some @ku-fpg packages to the build-constraints.yaml file for Stackage, but before I do that, I want to get @andygill's permission, because if we add these libraries to Stackage and they break in the future, it'll send him e-mail notifications :)

Just tell me how to help, @RyanGlScott, and we'll set things up.

You can add your packages to Stackage by making a pull request against fpco/stackage which modifies build-constraints.yaml accordingly. For example, if you applied this change:

diff --git a/build-constraints.yaml b/build-constraints.yaml
index 3fc560c..4d1d09a 100644
--- a/build-constraints.yaml

Then the blank-canvas, kansas-comet, dotgen, and data-reify packages will be explicitly added to Stackage as standalone libraries. Adding your username to the ku-fpg usermap will also make it so that if one of those packages breaks, it'll notify you. (This part is optional. Currently, it just notifies me :) )

I added myself as the Stackage maintainer for this package a while ago (see commercialhaskell/stackage@ea928b0bc), so this should no longer be an issue.
