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.
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.
<br>
Remember Program inherits from [Object](objects/Object.md)
## getStatus
returns the current process status
#### Returns:
1. `string` current status ("running", "normal, "suspended", or "dead")
#### Usage:
* Prints current status
```lua
local mainFrame = basalt.createFrame()
local aProgram = mainFrame:addProgram()
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
```lua
local mainFrame = basalt.createFrame()
local aProgram = mainFrame:addProgram()
aProgram:execute("rom/programs/fun/worm.lua") -- executes worm
```
```xml
<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
```lua
local mainFrame = basalt.createFrame()
local aProgram = mainFrame:addProgram()
aProgram:execute("rom/programs/fun/worm.lua") -- executes worm
mainFrame:addButton():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
```lua
local mainFrame = basalt.createFrame():show()
local aProgram = mainFrame:addProgram():execute("rom/programs/shell.lua"):show()
mainFrame:addButton():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
```lua
local mainFrame = basalt.createFrame():show()
local aProgram = mainFrame:addProgram():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
```lua
local mainFrame = basalt.createFrame():show()
local aProgram = mainFrame:addProgram():execute("rom/programs/shell.lua"):show()
mainFrame:addButton():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
```lua
local mainFrame = basalt.createFrame():show()
local aProgram = mainFrame:addProgram():execute("rom/programs/shell.lua"):show()
local events = {
{event="char", args={"h"}},
{event="char", args={"e"}},
{event="char", args={"y"}}
}
mainFrame:addButton():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
```lua
local mainFrame = basalt.createFrame():show()
local aProgram = mainFrame:addProgram():execute("rom/programs/shell.lua"):show()
mainFrame:addButton():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
```lua
local mainFrame = basalt.createFrame():show()
local aProgram = mainFrame:addProgram():execute("rom/programs/shell.lua"):show()
mainFrame:addButton():setText("inject"):onClick(function()
local events = aProgram:getQueuedEvents()
table.insert(events,1,{event="char", args={"w"}}
aProgram:updateQueuedEvents(events)
end):show()
```
