# What: tidalcycles installer script for OSX
#       tested on: Intel Big Sur 11.7.1
#       not tested on Silicon
# Change Log: Dec, 2022
#   - removed all commands for Linux
#   - replaced Atom install with Pulsar
#       - made Pulsar plugin install a separate section
#   - check for Intel vs Silicon vs anything else
#   - added support for DMG install (Pulsar, SuperCollider), removed zip format
#      if zip format is wanted again, revert via using a previous version
#   - changed cabal command to use v1-install tidal (note: continue to use cabal update)
#   - resolved bug when no shell profile is present (.bashrc or .zshrc) .ghcup/env initialization doesn't load properly
#      done by "touching" both files at top of script and changing test for Haskell install
#   - added test for SuperDirt install
#   - made code format changes per recommendations from shellcheck
#   - updated comments back to screen (user)
#############
## NOTES / known issues
# Install from DMG solution adapted from https://community.jamf.com/t5/jamf-pro/script-for-installing-dmg-pkg-zip-via-curl/m-p/157800
#    needed to get commands for working with macOS DMG file, which requires hdiutil to attach/detach (mount) the DMG
# Pulsar download URLs based on DOWNLOAD links instructions:
#  See https://github.com/pulsar-edit/package-frontend/blob/main/docs/download_links.md
#  Pulsar macOS downloads are currently unsigned.
#    As per https://pulsar-edit.dev/   xattr -cr /Applications/Pulsar.app  command needs to be run.
#  Pulsar plugin install is not reliable - it still may require manual install.
