Program objects are here for opening other executable programs in your main program. You can execute worms, shell or any custom program you've made.
Remember Program inherits from Object

getStatus

returns the current process status

Returns:

1. string current status ("running", "normal, "suspended", or "dead")

Usage:

• Prints current status

local mainFrame = basalt.createFrame("myFirstFrame"):show()
local aProgram = mainFrame:addProgram("myFirstProgram"):show()
basalt.debug(aProgram:getStatus())

execute

Executes the given path or program

Parameters:

1. string|function the path to your file as string, or function which should be called

Returns:

1. object The object in use

Usage:

• Executes worm

local mainFrame = basalt.createFrame("myFirstFrame"):show()
local aProgram = mainFrame:addProgram("myFirstProgram"):show()
aProgram:execute("rom/programs/fun/worm.lua") -- executes worm

<program path="rom/programs/fun/worm.lua" execute="true" />

stop

Stops a currently running program

Returns:

1. object The object in use

Usage:

• Stops worm by clicking a button

local mainFrame = basalt.createFrame("myFirstFrame"):show()
local aProgram = mainFrame:addProgram("myFirstProgram"):show()
aProgram:execute("rom/programs/fun/worm.lua") -- executes worm
mainFrame:addButton("myFirstButton"):setText("Pause"):onClick(function() aProgram:stop() end):show()

pause

pauses the current program (prevents the program from receiving events)

Parameters:

1. boolean true, false or nothing

Returns:

1. object The object in use

Usage:

• Pauses worm by clicking a button

local mainFrame = basalt.createFrame("myFirstFrame"):show()
local aProgram = mainFrame:addProgram("myFirstProgram"):execute("rom/programs/shell.lua"):show()
mainFrame:addButton("myFirstButton"):setText("Pause"):onClick(function() aProgram:pause(true) end):show()

isPaused

returns if the program is paused

Returns:

1. boolean pause status

Usage:

• Prints the pause status of the program

local mainFrame = basalt.createFrame("myFirstFrame"):show()
local aProgram = mainFrame:addProgram("myFirstProgram"):execute("rom/programs/shell.lua"):show()
basalt.debug(aProgram:isPaused())

injectEvent

injects a event into the program manually. For example you could inject w a s and d for worm, by clicking buttons.

Parameters:

1. string event
2. any parameter
3. any parameter
4. any parameter
5. any parameter
6. boolean if this is true, the injected event will be executed even if the program is paused

Returns:

1. object The object in use

Usage:

• injects a event by clicking a button

local mainFrame = basalt.createFrame("myFirstFrame"):show()
local aProgram = mainFrame:addProgram("myFirstProgram"):execute("rom/programs/shell.lua"):show()
mainFrame:addButton("myFirstButton"):setText("inject"):onClick(function() aProgram:injectEvent("char", "w") end):show()

injectEvents

Injects multiple events

Parameters:

1. table a table, items should be {event="event", args={para1, para2, para3, para4}}

Returns:

1. object The object in use

Usage:

• injects a multiple char events by clicking a button

local mainFrame = basalt.createFrame("myFirstFrame"):show()
local aProgram = mainFrame:addProgram("myFirstProgram"):execute("rom/programs/shell.lua"):show()

local events = {
{event="char", args={"h"}},
{event="char", args={"e"}},
{event="char", args={"y"}}
}
mainFrame:addButton("myFirstButton"):setText("inject"):onClick(function() aProgram:injectEvents(events) end):show()

getQueuedEvents

If the program is paused, incomming events will be inserted into a queued events table. As soon as the program is unpaused, the queued events table will be empty

Returns:

1. table a table - {event="event", args={"a", "b",...}}

Usage:

• prints the queued events table

local mainFrame = basalt.createFrame("myFirstFrame"):show()
local aProgram = mainFrame:addProgram("myFirstProgram"):execute("rom/programs/shell.lua"):show()
mainFrame:addButton("myFirstButton"):setText("inject"):onClick(function() basalt.debug(aProgram:getQueuedEvents()) end):show()

updateQueuedEvents

Here you can manipulate the queued events table

Parameters:

1. table a table, items should be {event="event", args={para1, para2, para3, para4}}

Returns:

1. object The object in use

local mainFrame = basalt.createFrame("myFirstFrame"):show()
local aProgram = mainFrame:addProgram("myFirstProgram"):execute("rom/programs/shell.lua"):show()

mainFrame:addButton("myFirstButton"):setText("inject"):onClick(function() 
local events = aProgram:getQueuedEvents()
table.insert(events,1,{event="char", args={"w"}}
aProgram:updateQueuedEvents(events) 
end):show()
