Auto disable hints if already exists the environment variable

• This issue's title and/or description do not reference a single formula e.g. brew install wget. If they do, open an issue at https://github.com/Homebrew/homebrew-core/issues/new/choose instead.

Provide a detailed description of the proposed feature

The idea is not to show the hint when there is any of the variables related to it.

For example, if HOMEBREW_AUTO_UPDATE_SECS or HOMEBREW_NO_AUTO_UPDATE is defined, it is understood that it is already configured and it does not make sense to show it.

What is the motivation for the feature?

Keeping the console clean.

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

By not having extra or unnecessary information, the command information can be seen more clearly.

What alternatives to the feature have been considered?

You could add a check of the variables before displaying it.

Can you provide an example of the specific hints you're seeing that you don't want to?

Hi @MikeMcQuaid

Sorry, but after checking it I have seen that in the brew.env file I misspelled the variable and after correcting it it is already hidden.

I have HOMEBREW_AUTO_UPDATE_SECS set explicitly to 86400 (in my ~/.zshrc).

❯ echo $HOMEBREW_AUTO_UPDATE_SECS
86400

I was hoping that this would hide the specific hint about auto updates, while still providing me with other env hints that I might find useful. However, I still get the hint: (EDIT: nope, user error, see below)

==> Auto-updating Homebrew...
Adjust how often this is run with HOMEBREW_AUTO_UPDATE_SECS or disable with
HOMEBREW_NO_AUTO_UPDATE. Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).

I also got this hint:

==> Running `brew cleanup coreutils`...
Disable this behaviour by setting HOMEBREW_NO_INSTALL_CLEANUP.
Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).

In this case, there seems to be no explicit configuration to set get the install cleanups, but that could be used to silence the hints.

❯ brew --version       
Homebrew 4.2.15

Hmm, but I do see now here that the HOMEBREW_AUTO_UPDATE_SECS hint should be hidden if explicitly set... so this might be an user error on my side as well, not sure how but looking at it :)

[skagedal]

Oh yes, the env var was not exported 🤦 – sorry about that. But how about the HOMEBREW_NO_INSTALL_CLEANUP case?

If I read the code right, there is no way to silence just this warning without disabling the behavior. So that would be a feature request.

There is: set HOMEBREW_NO_ENV_HINTS, as the message says.

Passing on this, sorry.

[skagedal]

No, that also disables other hints? But I of course realize that this is a rather specific ask and I perfectly understand that you would pass on it. :)

[MikeMcQuaid]

No, that also disables other hints?

Yes. We don't have hint-by-hint disabling, sorry.
