class Sys

Available on all platforms

This class gives you access to many base functionalities of system platforms. Looks in [sys] sub packages for more system APIs.

Class Fields

static function args():Array<String>

Returns all the arguments that were passed by the commandline.

static function command(cmd:String, ?args:Array<String> = null):Int

Run the given command with the list of arguments. The command output will be printed on the same output as the current process. The current process will block until the command terminates and it will return the command result (0 if there was no error). Read the [sys.io.Process] api for a more complete way to start background processes.

static function cpuTime():Float

Gives the most precise timestamp value (in seconds) but only account for the actual time spent running on the CPU for the current thread/process.

static function environment():StringMap<String>

Returns the whole environement variables.

static function executablePath():String

Returns the path to the current executable that we are running.

static function exit(code:Int):Void

Exit the current process with the given error code.

static function getChar(echo:Bool):Int

Read a single input character from the standard input (without blocking) and returns it. Setting [echo] to true will also display it on the output.

static function getCwd():String

Get the current working directory (usually the one in which the program was started)

static function getEnv(s:String):String

Returns the value of the given environment variable.

static function print(v:Dynamic):Void

Print any value on the standard output.

static function println(v:Dynamic):Void

Print any value on the standard output, followed by a newline

static function putEnv(s:String, v:String):Void

Set the value of the given environment variable.

static function setCwd(s:String):Void

Change the current working directory.

static function setTimeLocale(loc:String):Bool

Change the current time locale, which will affect [DateTools.format] date formating. Returns true if the locale was successfully changed

static function sleep(seconds:Float):Void

Suspend the current execution for the given time (in seconds).

static function stderr():Output

Returns the process standard error on which you can write.

static function stdin():Input

Returns the process standard input, from which you can read what user enters. Usually it will block until the user send a full input line. See [getChar] for an alternative.

static function stdout():Output

Returns the process standard output on which you can write.

static function systemName():String

Returns the name of the system you are running on. For instance :

"Windows", "Linux", "BSD" and "Mac" depending on your desktop OS.

static function time():Float

Gives the most precise timestamp value (in seconds).
