You need to use install, because install gives access to the static/*
files.
% cabal sandbox init
% cabal install
% cd wiki-suite
clone the documentation, which is also the test examples
% git clone https://github.com/ku-fpg/blank-canvas.wiki.git
% mkdir blank-canvas.wiki/tmp
build the tests
% cabal sandbox init --sandbox ../.cabal-sandbox/
% cabal install --only-d
% cabal build
and run them (on a mac)
% cabal test
you can compare output using github diff.
There is a script, wiki-suite/hack.pl, that compares blank-canvas.wiki with ORIG, using image compare.
