// The `SAMPLE_CODE_DISAMBIGUATOR` configuration is to make it easier to build
// and run a sample code project. Once you set your project's development team,
// you'll have a unique bundle identifier. This is because the bundle identifier
// is derived based on the 'SAMPLE_CODE_DISAMBIGUATOR' value. Do not use this
// approach in your own projects—it's only useful for sample code projects because
// they are frequently downloaded and don't have a development team set.

# MSG (Mac Subsystem for Guix)
## Description
MSG is an attempt to create a native-like experience for GUIX on MacOS, using methods inspired by others like Podman/Docker/Lima.
# !!!!Currently only compatible with M1/M2 Macs
## README (WIP)
**REQUIREMENTS**
- xquartz (if you want to run graphical applications)
- You also must go to Xquartz->Settings->Security->Enable 'Allow connections from network clients'
- Add the following to your shellrc file (~/.bashrc, ~/.zshrc, etc)
- ```
alias guix="ssh -i $HOME/.guix/ssh-cert/msg_rsa admin@msg.local 'guix'"
alias guix-shell="ssh -i $HOME/.guix/ssh-cert/msg_rsa admin@msg.local"
alias guix-env='f(){ ssh -i $HOME/.guix/ssh-cert/msg_rsa admin@msg.local /home/admin/.guix-profile /bin/$@; unset -f f; }; f'
alias guix-app='f(){ ssh -X -i $HOME/.guix/ssh-cert/msg_rsa admin@msg.local /home/admin/.guix-profile/bin/$@; unset -f f; }; f'
```
**INSTRUCTIONS**
- Drag the Guix.app file into your Applications directory and run!
**Available Commands (after adding bashrc/zshrc options)**
* guix : A straight passthrough to the guix application
* guix-shell: Connect to the vm over ssh
* guix-env : Can be used to pass cli commands interactively
* guix-app : Used to passthrough X11 applications from the vm to macos using xquartz
