the tidal suite

a simple stack.yaml + .cabal file
to build an isolated haskell environment
for a specific Tidal version (and specific addons)
and make emacs use it.

usage

this assumes you:

• have stack installed (in /usr/bin/stack)
• have emacs configured for (your main) tidal,
  that is: you require 'tidal somewhere on emacs init.

get the source:

git clone https://github.com/lennart/tidal-suite

build the environment

cd tidal-suite
stack setup && stack build

Test the installation

enter the isolated environment

stack repl --ghci-options=-XOverloadedStrings

and check whether we can access core tidal features:

GHCi, version 8.0.1: http://www.haskell.org/ghc/  :? for help

*Main Lib Sound.Tidal.Bjorklund Sound.Tidal.Context ... Sound.Tidal.Transition Sound.Tidal.Utils> :t cpsUtils
cpsUtils :: IO (Double -> IO (), IO Rational)

We let us show the type of the core action cpsUtils that returns what the pair that is commonly called cps and getNow. If this works, stack can load tidal.

Leave the stack repl with CTRL+C and then CTRL+D.

Running emacs

Start the editor from within the tidal-suite source folder:

emacs mod.tidal

Accept the question regarding the execution of .dir-locals.el
which sets up the tidal variables
tidal-interpreter
and tidal-interpreter-arguments
to load stack instead of the default ghci

Start up tidal in emacs, usually with CTRL+C CTRL+S
and to check whether you are loading the correct environment, evaluate

:show paths

via CTRL+C CTRL+C, which should list something like:

  /home/l/stack/tidal-suite
module import search paths:
  /home/l/stack/tidal-suite/src

depending on where you placed tidal-suite.

Wow, what's new?

In this case you are looking at the 0.9-dev versions of Tidal
and tidal-midi, which are not yet released on hackage.

This is a hopefully simple way to test these in combination and isolation.

You can try out the new features of tidal-midi 0.9, as exemplified in mod.tidal.

If you are developing on Tidal or tidal-midi or anything related to it, you can use this repository as a foundation to adapt from.

Change the .cabal file to your needs and versions of dependencies you require (add them to the library's build-depends key) and change the commit hashes or repository urls within stack.yaml. Choose different ghc versions, rely on the system ghc if you do not want to build a local one...
