Refactor the brew command into one file per command The code was sucking. To the extent that maintenance was hard. It's a lot easier to work with code that is sensibly split at sensible boundaries. So now it is more like that. But the refactor is minimal. Because we don't want you to have more merge hell than absolutely necessary. If you merge you will need to pay attention to brew.h.rb (as it is deleted) and bin/brew (as command logic is gone). It will be painful, but you will just have to help git out by moving any changes around manually. Note compatibility.rb. It ensures that any function renames or removals don't break anything. We're pretty serious about backwards compatibility. And that's because we encourage you to hack around with the innards. And we couldn't do that if we would then just make stuff disappear behind your back. 2010-09-11 20:22:54 +01:00			`def unlink`
If no formula but multiple kegs, advise resolution In this case the user will simply have to delete all but one keg in order to use the command that uses ARGV.kegs. Refs Homebrew/homebrew#11050. 2012-03-19 14:11:25 +00:00			`raise KegUnspecifiedError if ARGV.named.empty?`

FormulaInstaller: implement installation locks FormulaInstaller now attempts to take a lock on a "foo.brewing" file for the formula and all of its dependencies before attempting installation. The lock is an advisory lock implemented using flock(), and as such it only locks out other processes that attempt to take the lock. It also means that it is never necessary to manually remove the lock file, because the lock is not enforced by I/O. The uninstall, link, and unlink commands all learn to respect this lock as well, so that the installation cannot be corrupted by a concurrent Homebrew process, and keg operations cannot occur simultaneously. 2013-01-23 00:26:25 -06:00			`keg.lock do`

Add missing newline to link and unlink in verbose mode 2014-03-26 21:51:27 -05:00			`puts if ARGV.verbose?`
unlink: prefer "symlinks" since that's how it is reported by link cf. Homebrew/homebrew#28244. 2014-04-08 13:54:22 -05:00			`puts "#{keg.unlink} symlinks removed"`
