environment

Manipulates environment variables using an associative-array-like interface.

This class contains only static methods, and cannot be instantiated. See below for examples of use.

abstract final

class environment {

int errno [@property getter] via import core.stdc.errno : errno, EINVAL;;

static string opIndex(const(char)[] name);

static string get(const(char)[] name, string defaultValue);

static inout(char)[] opIndexAssign(char[] value, const(char)[] name);

static void remove(const(char)[] name);

static bool opBinaryRight(const(char)[] name);

static string[string] toAA();

}

Members

Static functions

get string get(const(char)[] name, string defaultValue): Retrieves the value of the environment variable with the given name, or a default value if the variable doesn't exist.
opBinaryRight bool opBinaryRight(const(char)[] name): Identify whether a variable is defined in the environment.
opIndex string opIndex(const(char)[] name): Retrieves the value of the environment variable with the given name.
opIndexAssign inout(char)[] opIndexAssign(char[] value, const(char)[] name): Assigns the given value to the environment variable with the given name. If value is null the variable is removed from environment.
remove void remove(const(char)[] name): Removes the environment variable with the given name.
toAA string[string] toAA(): Copies all environment variables into an associative array.
