If you need to build software on OS X by hand, a brew shell is the way to do it.
Closes Homebrew/homebrew#14381.
|
|
This is safe, I tested various scenarios, including Homebrew installed in ~. The only files that are removed are unexpected files in Homebrew's already managed directories.

Two wrapper scripts that find git and svn using the ENV variables we support and then searching through the PATH and looking inside Xcode.app if necessary.
Now just calling git or svn in Homebrew code will find and exec the right tool and we can stop fussing.
Apologies to @adamv who is probably unimpressed that the cmds directory has non-commands in it now. If it's consolation these are temporary pending some more work on superenv whereby some more directories are created under the superenv root.

Example useful usage:
eval $(brew --env gettext) && clang -Wl,-t -lssl 2>/dev/null

1. A minimal build environment, we don't set CFLAGS, CPPFLAGS, LDFLAGS, etc. the rationale being, the less that is set, the less variables we are introducing that can break builds.
2. A set of scripts that replace cc, ld, etc. and inject the -I, -L, etc. flags we need into the args passed to the build-tools.
Because we now have complete control over compiler instantiations we do a variety of clean-up tasks, like removing bad flags, enforcing universal builds and ensuring makefiles don't try to change the order of library and include paths from ones that work to ones that don't.
The previous ENV-system is still available when --env=std is specified.
superenv applies to Xcode >= 4.3 only currently.

Similar to the LinkedKegs record, we write a symlink for installed kegs to PREFIX/opt.
Unlike the linked-keg record, unlinking doesn't remove the link, only uninstalling, and keg-only formula have a record too.
The reason for this addition is so that formula that depend on keg-only formula can build against the opt directory and not the cellar keg. Thus surviving upgrades.
To enforce this fix_install_names and built were adapted to use the opt path.
Standard kegs also create an opt symlink so that caveats can now refer to the opt directory and thus provide steps that survive upgrades too.
Thus the choice of /opt. It is short, neat and the right choice: POSIX dictates that opt is for stand-alone prefixes of software.

If the Cellar doesn't exist yet, don't print an error message or exit
with an error status.
Fixes Homebrew/homebrew#14503.

The == comparison was comparing the versions rather than directly
comparing the strings, which lead to false positives.

Deprecated Formula.all, replaced usage with more appropriate enumerable options. Just check out how much nicer `brew audit` runs now.
|
|
|
|
Simplify access to the different forms of a formula's build options by
making options into real objects rather than strings, and expose both
the 'name' and 'flag' form.

Usually, the "foo-version already installed" error is printed by
FormulaInstaller. However, if an up-to-date formula that has outdated
deps is passed on the command line, we proceed to upgrade the deps and
then print a message saying that the formulae given on the command line
is already installed.
Catch this earlier, when the outdated list is being populated, print an
appropriate message, and skip the up-to-date formula.

This serves the same purpose as similar code in FormulaInstaller, but we
duplicate it because we do the dependency expansion in an ad-hoc fashion
here.

The heuristic for determining whether something is installed changes
from "f.installed?" to "f.rack.exist? and f.rack.subdirs.length > 0" in
order to properly consider outdated formulae.

Also made the latest_versions checks smarter. Hopefully correct too.

Apple's X11 is XQuartz, but this can be confusing, and is ultimately
unnecessary for debugging purposes.

This is coming up a lot at the moment, so here is an attempt to be more helpful.
|
|
-D is now the switch for diagnostic-dumps. Let it be so.
Shows how long each doctor method takes in a sorted table at end. I used this to move the two slowest methods to the end of the doctor run so that as much useful information can be shown as quickly as possible.
Also now possible to specify on command line which tests should be run.
|
|
Broke when I removed `require 'formula'` from ARGV.rb.
|
|
This was a regression which caused the bash completion script to
fail to complete formula options.
|
|
Probably slow, but we hate these fuckers.
|
|
Using :when_xquartz_installed will tell the keg-only machinery to activate
if XQuartz is installed.

When combining the set of old-style and new-style options, make sure
that the leading "--" is stripped.
Fixes displaying options in `brew options`, and the exotic case of
declaring options using the old syntax and then checking them with
`build.include?`

If you google for "Cowardly refusing to sudo brew" you get a lot of confused users who didn't read any of the Homebrew documentation and then had a hissy-fit.
