| # OS DEFINITIONS |
| # ============================================================================= |
| # |
| # We set these various is_FOO booleans for convenience in writing OS-based |
| # conditions. |
| # |
| # - is_android, is_chromeos, is_ios, and is_win should be obvious. |
| # - is_mac is set only for desktop Mac. It is not set on iOS. |
| # - is_posix is true for mac and any Unix-like system (basically everything |
| # except Fuchsia and Windows). |
| # - is_linux is true for desktop Linux, but not for ChromeOS nor Android (which |
| # is generally too different despite being based on the Linux kernel). |
| # |
| # Do not add more is_* variants here for random lesser-used Unix systems like |
| # aix or one of the BSDs. If you need to check these, just check the |
| # current_os value directly. |
