I want to work on a DSL that looks very similar to unit tests, define some steps but the steps are linked
step "step 1" do
IO.puts("hi")
end
step "step 2", depends: ["step 1"] do
IO.puts("bye")
end
Forcing a user to define a module at the top feels possibly distracting.
Two questions, one how should I go about loading an exs at runtime and calling it (I assume Code.compile_file
Second more important question, how might I go about dynamically generating a module or infering one maybe from the filename.
Where Next?

Dynamically generating modules is easier than you’d expect,
As for running a
.exsfile, I think your best bet would beCode.eval_file/2. Also, depending on what you’re looking to do, you may want to look intoReactor: README — reactor v1.0.2, as it may do what you’re looking to do already. And for defining the DSL you may look intoSpark: Spark — spark v2.7.2, which is a DSL building toolkit. Still sorely under-documented, but very feature rich. If you’re willing to read the tests to figure out how it works, then you’ll be A-ok. It’s very battle tested.jkbbwr
Id probably still have to wrap the content of the
.exsfile so I might end up using some sort of string eval.
