Netscript Bladeburner API
=========================

Netscript provides the following API for interacting with the game's Bladeburner mechanic.

The Bladeburner API is **not** immediately available to the palyer and must be unlocked
later in the game

**WARNING: This page contains spoilers for the game**

The Bladeburner API is unlocked in BitNode-7. If you are in BitNode-7, you will
automatically gain access to this API. Otherwise, you must have Source-File 7 in
order to use this API in other BitNodes

**Bladeburner API functions must be accessed through the bladeburner namespace**

In Netscript 1.0::

    bladeburner.getContractNames();
    bladeburner.startAction("general", "Training");

In :ref:`netscriptjs`::

    ns.bladeburner.getContractNames();
    ns.bladeburner.startAction("general", "Training");

.. _bladeburner_action_types:

Bladeburner Action Types
------------------------

Several functions in the Bladeburner API require you to specify an action using
its type and name. The following are valid values when specifying the action's type:

**Contracts**
    * contract
    * contracts
    * contr

**Operations**
    * operation
    * operations
    * op
    * ops

**Black Ops**
    * blackoperation
    * black operation
    * black operations
    * black op
    * black ops
    * blackop
    * blackops

**General Actions (Training, Field Analysis, Recruitment)**
    * general
    * general action
    * gen

**Bladeburner handler example**. Note that this avoids the need of using the *bladeburner* namespace
identifier by attaching the Bladeburner API functions to an object::

    const FIELD_ANALYSIS_INTERVAL = 10; //Number of minutes between field analysis states
    const FIELD_ANALYSIS_DURATION = 5;  //Duration in minutes

    function BladeburnerHandler(ns, params) {
