Static methods

Name	Description
Run	Runs a command line through the system shell (sh or cmd.exe) and waits for it.
IsWindows	True on Windows.
IsMacOS	True on macOS: the file that names the version of the system exists (/System/Library/CoreServices/SystemVersion.plist).
RunCapture	Runs a command line through the system shell and returns everything the program writes to stdout.
GetEnv	The value of the environment variable name.

Run

static int Run(StringSlice command)

Runs a command line through the system shell (sh or cmd.exe) and waits for it. What the program wrote before is written out first, so that the output of the command comes after it.

Returns the exit code of the program, or -1 if it could not be started.

IsWindows

static bool IsWindows()

True on Windows. The environment variable OS is not always passed on (e.g. by an MSYS2 login shell), so the system’s cmd.exe is looked for as well.

IsMacOS

static bool IsMacOS()

True on macOS: the file that names the version of the system exists (/System/Library/CoreServices/SystemVersion.plist). False on Windows, Linux, WebAssembly and AmigaOS.
