Thanks @yaxu!
I removed the hidden .ghc and .cabal files.
I did cabal update and then cabal v1-install tidal.
And now, I've got with cabal list tidal:
- tidal
Synopsis: Pattern language for improvised music
Default available version: 1.6.1
Installed versions: 1.6.1
Homepage: http://tidalcycles.org/
License: GPL-3
- tidal-midi
Synopsis: MIDI support for tidal
Default available version: 0.9.10
Installed versions: [ Not installed ]
Homepage: http://tidal.lurk.org/
License: GPL-3
- tidal-serial
Synopsis: Serial support for tidal
Default available version: 0.8
Installed versions: [ Not installed ]
Homepage: http://tidalcycles.org/
License: GPL-3
- tidal-vis
Synopsis: Visual rendering for Tidal patterns and osc messages
Default available version: 1.0.15
Installed versions: [ Not installed ]
Homepage: http://yaxu.org/tidal/
License: GPL-3
So, thanks to cabal v1-install tidal, Tidal is installed, whereas it was mentioned it was not installed with cabal install tidal --lib. do not know why?
I do also not know why e.g. tidal-midi is mentioned as not installed ?, (midi support is important to me)
Concerning cabal list hosc, I've got:
(base) xon-5:~ xon$ cabal list hosc
- hosc
Synopsis: Haskell Open Sound Control
Default available version: 0.18.1
Installed versions: 0.18.1
Homepage: http://rohandrape.net/t/hosc
License: GPL-3
- hosc-json
Synopsis: Haskell Open Sound Control JSON Serialisation
Default available version: 0.16
Installed versions: [ Not installed ]
Homepage: http://rd.slavepianos.org/t/hosc-json
License: GPL
So hoc is installed now and import Sound.OSC under ghci works.
But still, I have the same kind of error message I mentioned before when I do npm start.
@mrreason, I can send you the complete error message if you want.
[client] *** Exception: Network.Socket.connect: <socket: 14>: does not exist (Connection refused)
[client]
Also, now, when I launch Atom and boot Tidal, I've got:
Choose ghcup default path: /Users/xon/.ghcup/bin
Ghci command: /Users/xon/.ghcup/bin/ghci
Ghc-pkg command: /Users/xon/.ghcup/bin/ghc-pkg
And if evaluate a line, I've got some sound, but it is printed:
Load BootTidal.hs from /Users/xon/.cabal/share/x86_64-osx-ghc-8.8.4/tidal-1.6.1/BootTidal.hs
t>
t>
t>Listening for controls on 127.0.0.1:6010 Control listen failed. Perhaps there's already another tidal instance listening on that port?
When I first installed Tidal, it seems to me, I had not all these lines printed and Tidal was booting directly...
