#3830 Homebrew tap README omits the brew trust step Homebrew 7 requires, so brew install swamp refuses the formula

Opened by reset · 10/23/2026

On a Mac with Homebrew 7.0.9, following the tap README (brew tap swamp-club/tap then brew install swamp) stops at Error: Refusing to load formula swamp-club/tap/swamp from untrusted tap. Homebrew 7 refuses third-party formulae until the tap is trusted. The README at https://github.com/swamp-club/homebrew-tap/blob/main/README.md (checked at the 20261020.024627.0-sha.26dc044f formula commit) has only the two lines brew tap swamp-club/tap and brew install swamp; grep -i trust README.md matches nothing. The manual's install page (/manual/how-to/install-swamp) lists only the curl ... | sh installer, so the README is the only place the Homebrew route is written down.

Expected: the README's install steps run to completion on a current Homebrew. Actual: the second step refuses until the user discovers brew trust swamp-club/tap on their own.

Steps to reproduce:

  1. On Homebrew 7.x with no prior trust record for the tap, brew tap swamp-club/tap.
  2. brew install swamp -> Refusing to load formula swamp-club/tap/swamp from untrusted tap.
  3. brew trust swamp-club/tap then brew install swamp succeeds.

#738 (closed) is where the official tap was pointed out; it predates the Homebrew 7 trust requirement.

Suggestion: add brew trust swamp-club/tap between the tap and install lines in the README (and on the install page if a Homebrew section is ever added).
