• My "brew doctor output" above says Your system is ready to brew. and am still able to reproduce my issue.
• I ran brew update twice and am still able to reproduce my issue.

What were you trying to do (and why)?

List all outdated apps with corresponding versions, including HEAD.

What happened (include all command output)?

$ brew outdated             
hwloc (2.11.0) < 2.11.1
usb.ids (2024.03.18) < 2024.07.04
pixelflasher (6.8.0.4) != 7.0.0.0

$ brew outdated --fetch-HEAD
hwloc
usb.ids
pixelflasher

--verbose flag doesn't make any difference, as well as --formulae flag, which just skips casks.

What did you expect to happen?

brew outdated --fetch-HEAD should show upgrades with corresponding version changes, at least non-head ones.

Step-by-step reproduction instructions (by running brew commands)

You don't need to have any HEAD formula installed to see the difference between the following two commands, given you have at least one outdated app.

$ brew outdated
$ brew outdated --fetch-HEAD

🤔 I can't reproduce this:

$ brew outdated
deckset (2.0.25,2636) != 2.0.32,2687
font-anonymice-nerd-font (3.0.2) != 3.2.1
font-fira-code-nerd-font (3.0.2) != 3.2.1
font-monofur-nerd-font (3.0.2) != 3.2.1

$ brew outdated --fetch-HEAD
deckset (2.0.25,2636) != 2.0.32,2687
font-anonymice-nerd-font (3.0.2) != 3.2.1
font-fira-code-nerd-font (3.0.2) != 3.2.1
font-monofur-nerd-font (3.0.2) != 3.2.1

Closing until a maintainer can reproduce.

I'm seeing this on one two of my installations. Adding a ohai Context.current.inspect to cmd/outdated.rb's print_outdated shows that --fetch-HEAD is causing @quiet=true and other values to be nil, in both bash and zsh. Other machines are fine.

$ brew outdated --formula -v | head -n 5
==> #<Context::ContextStruct:0x00000001141b3e50 @debug=false, @quiet=false, @verbose=true>
autoconf (2.71) < 2.72
bdw-gc (8.0.6) < 8.2.6
boost (1.78.0_1) < 1.85.0
c-ares (1.18.1_1) < 1.32.1

$ brew outdated --formula -v --fetch-HEAD | head -n 5
==> #<Context::ContextStruct:0x000000010d854ab8 @debug=nil, @quiet=true, @verbose=nil>
autoconf
bdw-gc
boost
c-ares

It only occurs if any keg was installed using --HEAD and is up-to-date.

$ brew outdated --formula -v flac123
flac123 (HEAD-d969f2c_1) < 2.1.1
$ brew outdated --formula -v --fetch-HEAD flac123
flac123 (HEAD-d969f2c_1) < 2.1.1

$ brew outdated --formula -v flac123 libpng
flac123 (HEAD-d969f2c_1) < 2.1.1
$ brew outdated --formula -v --fetch-HEAD flac123 libpng
