Also adjust output text slightly for prettiness.
A possibly useful side effect here is safe_system has a defined Exception (subclassing RuntimeError) now.
Mirrors can now be declared using the `mirror` method which works similar to
`depends_on` and takes the same arguments as `url`.
The formula class now has a public `fetch` method that cycles through the
mirror list if the downloader for the primary URL throws a `DownloadError`.
Other brew commands, like brew-fetch, also benefit from mirror support by using
this method.
ClosesHomebrew/homebrew#7574.
`rack` is a commonly used alias for `formula.prefix.parent`---so common that it
gets defined and used quite a bit. This patch makes `rack` an official method
of the `Formula` class.
The compiler setting in the xcodeproj is overridden by the CC setting in the environment. This is a bit insane IMO since the xcodeproj itself has detailed decisions about what tools to use.
FixesHomebrew/homebrew#6406.
This is used with fails_with_llvm so that if GCC cannot be found (and we suspect this is the case with Xcode 4.2) the build will fail.
Quite possibly it should be the default.
Executing `curl(*patches)` was failing on Leopard when `patches` was an empty
list. `git-bisect` identified 48552bb42a69ece4eb2a6d9acf81a0b47adb19c9 as the
commit that caused this bug to surface by adding `--insecure` to the arg list
on Leopard. This is odd because the following both exit with status 2:
curl
curl --insecure
The only apparent difference is that `curl --insecure` prints "no URL
specified!" to stderr along with the usage message.
Also renamed `patches` to `external_patches` as it is more descriptive.
Deprecated use_clang? etc. since the logic was such that multiple states could be set, when in reality only one compiler can be set.
Changed fails_with_llvm handling so if HOMEBREW_USE_LLVM is set then it tries to build even if the formula has fails_with_llvm set. Rationale: mostly they will no longer fail and we need to catch these cases.
Bottles now pour purely, without doing all the other unnecessary stuff that happened before the `brew upgrade` code shuffle.
Formula.pourable? removed since it was install-specific metadata and not related to the formula itself. Now all such logic is in the FormulaInstaller which is much cleaner.
I also changed the bottle cache location to the normal directory and added a .bottle pre-extension. Thus you can see everything in one directory without messing about.
* may be a problem if the constant is scoped (like A::B), but this is not the case
(const.split('::').inject(Object) { |c, part| c.const_get part } would solve that)
* this was noticed in a comment of 9afc85ad but it has disappeared
