possible to customize plist on start

[itcarroll]

Is it possible to use any kind of variables or templating in a formula's service block that wouldn't get interpolated until writing the service file during brew services start ...?

The jupyterlab formula defines a service that includes log_path var/"log/jupyterlab.log". I'm trying to get the per-user plist files (i.e. what homebrew-services writes into ~/Library/LaunchAgents/) to have the StandardOutPath set to ~/Library/Logs/ rather than into the (write protected) homebrew prefix.

Sorry, this is not possible in brew services. It may be possible through pull requests to Homebrew/brew. Opening a pull request there may be your best bet.

This document should help and we're happy to walk you through anything else.

Thanks!
