This is the sample code to accompany the book Haskell in Depth (Vitaly Bragilevsky, Manning Publications 2020).
To get the source code on your system, you may want to clone this repository:
$ git clone https://github.com/bravit/hid-examples.git
To work with the code on your system, you need either:
To build the whole package, issue the following command:
$ cabal build
To build only one project component:
$ cabal build hello
To run a component:
$ cabal run hello
Up to date
Hello, world
$ cabal -v0 run hello
Hello, world
$ cabal run stockquotes -- data/quotes.csv -p -v
...
To explore a component in GHCi:
$ cabal repl hello
...
$ cabal repl stockquotes
ghci> :load Statistics
To test the whole package:
$ cabal test
To run one test-suite:
$ cabal test locator-test
To build:
stack build
To run:
stack exec <executable> [ -- <arguments>]
For example:
stack exec stockquotes -- data/quotes.csv -p -v
To test:
stack test
Unfortunately, exploring code in GHCi doesn't work due to bug in stack:
stack ghci <module file>
