Load Environmental Variables Via Script Commands In cargo make

May 2024

I don't like storing credentails in plain-text. Aside from the possibilty of accidentally committing them to a repo I also stream. That opens up another way to dox myself.

Whenever possible (which is close to always), I store my credentails in a password manager and then pull them into my processes programatically. For example, I can create put a credentail in macOS's KeyChain Access app and then access it in a cargo make¹ Makefile.toml with:

[env]
MY_PASSWORD = { script = ["security find-generic-password -w -a alan -s some-password-name"] }
SOME_CREDENTAIL = { script = ["cat /Users/username/.ssh/Credentails.txt | xargs"]

Notes

That makes $MY_PASSWORD available in all the [tasks.task_name] tasks during the run.
The pass to xargs in the cat example is to remove trailing whitespace from the Crednetials.txt file which is part of Apples process of signing and notarizing Tauri apps for macs. Without the xargs I was getting:

Info setup keychain from environment variables...
  Error failed to bundle project: failed to import keychain certificate
