system

This module provides information about the system where sjs is running as well as the environment. It implements CommonJS System/1.0 with some extras.

Attributes

system.versions

An object containing information about the sjs and embedded Duktape versions.

sjs> print(JSON.stringify(system.versions, null, 4))
{
    "duktape": "v1.5.0",
    "duktapeCommit": "83d5577",
    "sjs": "0.1.0"
}

system.env

Array containing the current environment variables.

system.path

Array containing the list of locations which are going to be used when searching for modules. It can be modified at runtime.

A list of colon separated paths can also be specified with the SJS_PATH variable, which will be prepended to the default paths list.

system.arch

System architecture (x86, x64 or arm).

system.platform

String representing the running platform (linux or osx).

system.executable

Absolute path of the executable that started the process.

system.argv

Set of command line arguments that were given to the process.

./build/sjs t.js -i -o --verbose
// [ './build/sjs', 't.js', '-i', '-o', '--verbose' ]

system.args

Similar to argv, except that the interpreter binary is not listed. This is to conform with CommonJS System/1.0.

./build/sjs t.js -i -o --verbose
// [ 't.js', '-i', '-o', '--verbose' ]

system.build

Object providing various information about the build and the system where it was produced:

sjs> print(JSON.stringify(system.build, null, 4))
{
    "compiler": "GCC",
    "compilerVersion": "5.3.1",
    "system": "Linux-4.5.0-1-amd64",
    "cflags": "-pedantic -std=c99 -Wall -fstrict-aliasing -fno-omit-frame-pointer -Wextra -O0 -g3",
    "timestamp": "2016-05-07T17:37:46Z",
