git clone this EP repository (https://github.com/combinators/expression-problem) and then switch to the archived branch.
git checkout archived
You will then need to modify the build.sbt file because the Scala Version is so out of date. The following works.
scalaVersion := "2.12.17"
Launch sbt and then you can generate code solutions in different languages.
In sbt, execute the command language-java/run.
Now in a separate terminal window request access to a git repository that would be generated, something like:
git clone http://localhost:9000/algebra/m5/m5.git
The pattern of all of these requests is:
git clone http://localhost:9000/{approach}/{stage}/{stage}.git
Valid values include:
- stage: m0, m1, m2, m3, m4, m5, m6, m7, m8, i1, i2, p1, s0, s1, c1
- approach: algebra, extensibleVisitor, interpreter, oo, trivially, visitor
In sbt, execute the command language-haskell/run.
Now in a separate terminal window request access to a git repository that would be generated, something like:
git clone http://localhost:9000/grow/m4/m4.git
Valid values include:
- stage: m0, m1, m2, m3, m4
- approach: alacarte, grow
In sbt, execute the command language-gj/run.
Now in a separate terminal window request access to a git repository that would be generated, something like:
git clone http://localhost:9000/wadler/m1/m1.git
Valid values include:
- stage: m0, m1
- approach: wadler
