Demonstrate use of typeclasses and simple monad transformer stacks to structure haskell apps
View pragmatic.hs
-- This is a small example for structuring Haskell programs so that
-- you neither have to 1) define half your program to live in IO or
-- 2) build complex Monad transformer stacks where you have to lift
-- several times to be able to do the correct operations.
-- Instead, this approach (shown to me by @am_i_tom at BusConf 2018)
-- uses type classes that define a set of operations and then define
-- a type `App a` that is a small Monad transformer stack of EitherT,
-- ReaderT and IO that implement these type classes. This allows
-- you to write functions that declare (via these type classes) which
-- capabilities they need to run. You can also easily write a different

Simple recipe for how to regenerate swagger based apis without overwriting implementation
java -jar swagger-codegen-cli.jar generate -l python-flask -i SWAGGER-YAML-FILE -o api
git add api
git commit ...
# this is just a convienience for the first time you change your api
git tag -a initial-api-scaffold -m "Initial swagger scaffold. Base point for future api changes"
# work on implementation, then:
git add, commit

-- This is a naive brainstorm draft for a binary parser for an imaginary binary image format.

-- 2 bytes: width of image in pixels
-- 2 bytes: height of image in pixels
