Brew: $HOMEBREW_NO_BOLD to disable bold in output

[nhooyr]

A detailed description of the proposed feature

I'd like setting $HOMEBREW_NO_BOLD to disable bold in the output. This is different from $HOMEBREW_NO_COLOR as it keeps color in the output otherwise.

The motivation for the feature

I bold my prompt so that I can easily scan for it in my output but when another program has bold in its output, it becomes difficult to easily scan for my prompt.

How the feature would be relevant to at least 90% of Homebrew users

This seems to be a very high bar, I strongly doubt even 10% of Homebrew's users enable $HOMEBREW_NO_COLOR. I feel like a lot of people would prefer this as a middle ground between $HOMEBREW_NO_COLOR and $HOMEBREW_COLOR as it's really only the bolds that make the colors so aggressive.

What alternatives to the feature have been considered

I use $HOMEBREW_NO_COLOR right now but it makes it much harder to scan Homebrew's output with zero colors. I can also use set $HOMEBREW_COLOR to force color and then use sed to replace the bold escape sequences but like I mentioned above, I feel like a lot of people would enjoy this.

No strong opinion about the proposal but:

This seems to be a very high bar, I strongly doubt even 10% of Homebrew's users enable $HOMEBREW_NO_COLOR.

Thank you for being honest.

In case my proposal is rejected, I worked out how to do this with sed:

brew() {
  HOMEBREW_COLOR=1 command brew "$@" | sed -E "s/"$'\e'"\[1m//g"
}

You can also get rid of the brew emoji as so:

brew() {
  HOMEBREW_COLOR=1 command brew "$@" | sed -e "s/"$'\e'"\[1m//g" -e "s/🍺/  /"
}

There is precedence for this feature in fzf. See https://github.com/junegunn/fzf/commit/4b332d831e3b5cb6dc70484b1a621eae9b162317

This is something we may reconsider in future but we'd want to see demand from non-trivial numbers of users for this (particularly given there's a workaround for this).

You can also get rid of the brew emoji as so:

HOMEBREW_NO_EMOJI will do this for you. It's documented in man brew.

[nhooyr]

Got it. I've ended up rocking the following to underline instead of bold and remove the emoji.

export HOMEBREW_NO_EMOJI=1

brew() {
  # Replace bold with underline.
  # https://github.com/Homebrew/brew/issues/7753
  HOMEBREW_COLOR=1 command brew "$@" | sed "s/"$'\e'"\[1m/"$'\e'"\[4m/g"
}

Harder to read the output without bold or underlines.

[nhooyr]

oo you don't have to hard code the sequences.

export HOMEBREW_NO_EMOJI=1

tputq() {
  tput "$@" | sed "s#\[#\\\[#"
}

brew() {
  # Replace bold with underline.
  # https://github.com/Homebrew/brew/issues/7753
  HOMEBREW_COLOR=1 command brew "$@" | sed "s/$(tputq bold)/$(tputq smul)/g"
}
