a-shell uses ios_system https://github.com/holzschu/ios_system/ and can install WASM packages (if they exist?) iSH emulates 32-bit alpine x86 and can install things from apk

This was fun to try as a little preview of what it’ll feel like to have an ARM-based MacBook. Bummer there’s no git¹. I was curious to try to install Go just to see how far I’d get before being blocked. Was able to download the source tarball and extract it (using curl and tar as 2 separate commands; piping curl into tar didn’t work). But then can’t execute make.bash because there’s no bash. [1] There's rationale and an alternative described at https://github.com/holzschu/ios_system#adding-more-commands.

From the README: https://github.com/holzschu/ios_system/blob/master/README.md Issues: In iOS, you cannot write in the ~ directory, only in ~/Documents/, ~/Library/ and ~/tmp. Most Unix programs assume the configuration files are in $HOME. So either you redefine $HOME to ~/Documents/ or you set configuration variables (using setenv) to some other place. This is done in the initializeEnvironment() function. Here's what I have: setenv PATH = $PATH:~/Library/bin:~/Documents/bin setenv PYTHONHOME = $HOME/Library/ setenv SSH_HOME = $HOME/Documents/ setenv CURL_HOME = $HOME/Documents/ setenv HGRCPATH = $HOME/Documents/.hgrc/ setenv SSL_CERT_FILE = $HOME/Documents/cacert.pem Your Mileage May Vary. Note that iOS already defines $HOME and $PATH.

This is extremely cool. Is there any documentation on what shell syntax this supports? I assume it's not running a standard shell like Bash or zsh. Edit: https://github.com/holzschu/ios_system/blob/master/README.md confirms its not running sh, bash, or zsh, and has some additional details on the available commands. I still think it would be nice for this to be more explicit, but the information is out there.

This is just a very simple frontend to this library: https://github.com/holzschu/ios_system That library is just a simple implementation of some basic commands. It does not do any executable execution, it does not use the real system utilities. Nor does it has anything to do with Bash, or shell scripts. It’s just basically one big ‘switch’ for all commands, which are implemented in the app itself.
