Back to really working toward an Android webapp now. I have been improving the EvilSplicer, and the build machinery, and build environment all day. Slow but steady progress.
First milestone of the day was when I got yesod-form
to build with all
Template Haskell automatically expanded by the EvilSplicer. (With a few
manual fixups where it's buggy.)
At this point the Android build with the webapp enabled successfully builds several files containing Yesod code.. And I suspect I am very close to getting a first webapp build for Android.
