We need a test for this.

Closes Homebrew/homebrew#116
|
|
|
|
Thus install.rb gets the path to the instantiating brew process rather than whichever is first in the PATH. Not to mention Homebrew doesn't *have* to be in the PATH.
|
|
Because it's a global.h constant and that file can be included by other projects.
|
|
It's a constant and Dir.getwd can change.

We trap the INT in the install process now so the newline race condition is avoided. Much neater and more polished now.

Generally this isn't desired or useful.

Couldn't make this atomic, apologies.
Fixes a few things, like deps failing to build not aborting the install.
--force now works properly again.
Overall more robust code. I went back over it all and gave it a lot of
thought.
Cleaner separation of logic. Less code in brew, now the only code there is
ARGV handling, and basic sanity checks.
Not extending ARGV or ENV in global now as that would propagate to other tools
or utilities you may write.

Only unlink the keg, don't prune. That's enough, we shouldn't do general maintenance anyway.

This rewrite attempts to sort out where the Prefix, Cellar, and
Repository are relative to the real and symlinked 'brew' command.
Also included is a --config option which dumps all of these variables.
Any top-level script must define a "BREW_FILE" that gives the path
to brew as it exists in the path. 'brew' itself just uses __FILE__ and
install.rb does a `which brew` (there may be a better way?)
The Prefix is always relative to the location of brew as it exists in
the path. Thus, whether or not /usr/local/bin/brew is a symlink or real
file, the Prefix is always /usr/local. If you have brew in some other
prefix, such as /nonstandard/bin/brew, then '/nonstandard/ will be
managed by brew instead.
The Repository, Cellar, and "Library/Homebrew" required code is always
found relative to the "real" path or brew. If brew is a real file in
/usr/local/bin/brew, then everything else will be found in /usr/local
and we'll expect a /usr/local/.git
Otherwise, we dereference brew's symlink and look for everything else
relative to that path instead.

Using an error pipe.
The use of ENV[HOMEBREW_ERROR_PIPE] feels wrong, but I wasn't sure how else to
proxy the file descriptor to the child process since the fork immediately
calls exec.
|
|
Ruby throws if CWD doesn't exist, even when you aren't doing anything related to the CWD. Sucks. So at least show the user a friendly error message rather than looking broken.

Since plenty of formula don't require it, I don't want to insist on gcc being installed. A better check is if gcc is required then check for version 4.2, which is all we support.
However I can't easily do that. So I'm risking bug reports from people who didn't read the installation instructions and didn't install the right Xcode. But they deserver derision :P

The classes better reflect their contents. I'm sure this change may be
contentious, but I am a sucker for trying to create source bases that are easy
to get to grips with and easy to navigate.
brewkit.rb is now a deprecated file.
|
|
This works better as it comes after any keg-only deps change ENV, but also it needs to happen after brewkit is required and that only happens in install now.
|
|
brewkit.rb changes ENV destructively, so lets not do that everytime a formula
is required. Now it's possible for other tools to require a formula
description without worrying about side-effects.
|
|
Mainly because this feature is for devs and the code is too messy to fix it properly yet.

`brew list` fails after fresh install because Cellar directory doesn't exist yet.

Follow symlinks when trying to find HOMEBREW_RUBYLIB.

This is now supported usage, it wasn't before. I amended the patch quite heavily because it broke our other supported usage, ie. complete symlinking of Homebrew into /usr/local

Determine all directories that aren't Homebrew ones.
Exec find.
I prefer to keep short stuff in bin/brew so people reading the code have a better idea of what happens, and what sort of functions are useful for the sorts of things we do with Homebrew.

Very quick way to find files not installed by homebrew.
Taken from a command by mxcl on the homebrew wiki.
.DS_Store files and bin/brew are ignored.

We shouldn't mess with the user's PATH anyway. So assume our users are smart and just warn them about potential issues instead.

Axel tries to accelerate downloads by using multiple connections (possibly to
multiple servers) for one download. Because of its size, it might be very
useful on bootdisks or other small systems as a wget replacement.

I adapted it slightly based on the user agent that Safari gives.

I'm trying to only show the interesting stuff. You can see a full listing with
brew -v list, or by piping to other commands.
Tell me if you hate it or love it.

Shows the git-log for that formula.
