I've adjusted test-bot in:
603918939a
to set CI=1 for Jenkins to make future JENKINS_HOME checks unnecessary.
The only `TRAVIS_*` variable we care about is `TRAVIS_SUDO` so whitelist
that specifically rather than passing through loads of others.
Ensure that the various variables are passed through and reset
correctly. If we end up doing this in a bunch of places we may add some
helpers to simplify this.
- only document HOMEBREW_* variables in the manpage (although still
read from all the original environment variables).
- resort manpage environment variables in alphabetical order
- check the original path for trailing slashes
For many people `brew edit` makes use of the `EDITOR` variable to pick a
sensible editor. With environment filtering enabled unless this editor
is found in the default system PATH it'll fall back to e.g. `vim`.
Instead, ensure that we export the original, pre-filtering `PATH` as
`HOMEBREW_PATH` and use that internally to locate the editor. In future
this same approach will likely be used for requirements to be able to
find tools, too, and for other variables which we want to expose to
Homebrew itself but not other build tools.
Note that `HOMEBREW_PATH` is the same as `PATH` when build filtering
hasn't been enabled.
Just sourcing brew.sh causes the "Example usage" msg due to lacking command args but changing the last line of your suggestion to:
/bin/bash "$HOMEBREW_LIBRARY/Homebrew/brew.sh" "$@"
worked.
If all of the 'HOMEBREW.*' vars, that other parts of the system require, are only added in brew.sh then your suggestion is cleaner.
If `/usr/local` is the prefix but not the repository (so bottles can be
used) then running `/usr/local/bin/brew` works great but
`$HOMEBREW_REPOSITORY/bin/brew` assumes the prefix is
`$HOMEBREW_REPOSITORY`. This is a pain when doing work on the Homebrew
repository and having e.g. `bin` in your `$PATH`. Improve this
behaviour so `bin/brew` knows how to handle this situation.
If `bin/brew` happens to be symlinked to `/brew`, `/bin/brew`, or some
similar location or (worse yet) Homebrew is installed to `/`, then
computation of the prefix and/or repository path could break down and
result in an invalid or empty path.
ClosesHomebrew/homebrew-core#2430.
This is inspired by `quiet_system` with basically the same implication
(suppress output), making the name a lot less confusing and avoiding a
clash with the `chdir` function defined in `Library/brew.sh`.
`bin/brew` is getting a bit bloated and it's annoying to open all of
`HOMEBREW_PREFIX` in your editor of choice and have it search through
the `Cellar`. Let's instead keep the bare minimum in `bin/brew` and
move the rest to `Library`.

This means that internal command aliases can be used for Bash commands
(such as the new, Bash-based `brew update`).
