Chandler Carruth f7364d5833 Add support for linking against a curses library when available and ... using it to detect whether or not a terminal supports colors. This replaces a particularly egregious hack that merely compared the TERM environment variable to "dumb". That doesn't really translate to a reasonable experience for users that have actually ensured their terminal's capabilities are accurately reflected. This makes testing a terminal for color support somewhat more expensive, but it is called very rarely anyways. The important fast path when the output is being piped somewhere is already in place. The global lock may seem excessive, but the spec for calling into curses is *terrible*. The whole library is terrible, and I spent quite a bit of time looking for a better way of doing this before convincing myself that this was the fundamentally correct way to behave. The damage of the curses library is very narrowly confined, and we continue to use raw escape codes for actually manipulating the colors which is a much sane system than directly using curses here (IMO). If this causes trouble for folks, please let me know. I've tested it on Linux and will watch the bots carefully. I've also worked to account for the variances of curses interfaces that I could finde documentation for, but that may not have been sufficient. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187874 91177308-0d34-0410-b5e6-96231b3b80d8		2013-08-07 08:47:36 +00:00
