Con Namespace Reference

Detailed Description

This namespace contains the core of the console functionality.

Introduction

The console is a key part of Torque's architecture. It allows direct run-time control of many aspects of the engine.


Control Functions

The console must be initialized and shutdown appropriately during the lifetime of the app. These functions are used to manage this behaviour.

Note:
Torque deals with this aspect of console management, so you don't need to call these functions in normal usage of the engine.


void init ()
 Initializes the console.
void shutdown ()
 Shuts down the console.
bool isActive ()
 Is the console active at this time?

Console Consumers

The console distributes its output through Torque by using consumers. Every time a new line is printed to the console, all the ConsumerCallbacks registered using addConsumer are called, in order.

Note:
The GuiConsole control, which provides the on-screen in-game console, uses a different technique to render the console. It calls getLog() to get the on-screen console entries, then renders them as needed.

Special Purpose Registration

These are special-purpose functions that exist to allow commands to be grouped, so that when we generate console docs, they can be more meaningfully presented.

Click here for more information about console docs and grouping.

Enumeration Type Documentation

enum Con::Constants
 

Various configuration constants.

Enumeration values:
DSOVersion  This is the version number associated with DSO files.

If you make any changes to the way the scripting language works (such as DSO format changes, adding/removing op-codes) that would break compatibility, then you should increment this.

If you make a really major change, increment it to the next multiple of ten.

MaxLineLength  Maximum length of a line of console input.
MaxDataTypes  Maximum number of registereed data types.

Function Documentation

void Con::init (   ) 
 

Initializes the console.

This performs the following steps:

  • Calls Namespace::init() to initialize the scripting namespace hierarchy.
  • Calls ConsoleConstructor::setup() to initialize globally defined console methods and functions.
  • Registers some basic global script variables.
  • Calls AbstractClassRep::init() to initialize Torque's class database.
  • Registers some basic global script functions that couldn't usefully be defined anywhere else.

void Con::shutdown (   ) 
 

Shuts down the console.

This performs the following steps:

  • Closes the console log file.
  • Calls Namespace::shutdown() to shut down the scripting namespace hierarchy.

bool Con::isActive (   ) 
 

Is the console active at this time?

void Con::addConsumer (  ConsumerCallback  cb  ) 
 

void Con::removeConsumer (  ConsumerCallback  cb  ) 
 

void Con::stripColorChars (  char *  line  ) 
 

Remove color marking information from a string.

Note:
It does this in-place, so be careful! It may potentially blast data if you're not careful. When in doubt, make a copy of the string first.

bool Con::expandScriptFilename (  char *  filename,
U32  size,
const char *  src
) 
 

Convert from a relative script path to an absolute script path.

This is used in (among other places) the exec() script function, which takes a parameter indicating a script file and executes it. Script paths can be one of:

  • Absolute: fps/foo/bar.cs Paths of this sort are passed through.
  • Mod-relative: ~/foo/bar.cs Paths of this sort have their replaced with the name of the current mod.
  • File-relative: ./baz/blip.cs Paths of this sort are calculated relative to the path of the current scripting file.

Note:
This function determines paths relative to the currently executing CodeBlock. Calling it outside of script execution will result in it directly copying src to filename, since it won't know to what the path is relative!
Parameters:
filename Pointer to string buffer to fill with absolute path.
size Size of buffer pointed to by filename.
src Original, possibly relative script path.

bool Con::isFunction (  const char *  fn  ) 
 

Returns true if fn is a global scripting function.

This looks in the global namespace. It also checks to see if fn is in the StringTable; if not, it returns false.

U32 Con::tabComplete (  char *  inputBuffer,
U32  cursorPos,
U32  maxResultLength,
bool  forwardTab
) 
 

This is the basis for tab completion in the console.

Note:
This is an internally used function. You probably don't care much about how this works.
This function does some basic parsing to try to ascertain the namespace in which we are attempting to do tab completion, then bumps control off to the appropriate tabComplete function, either in SimObject or Namespace.

Parameters:
inputBuffer Pointer to buffer containing starting data, or last result.
cursorPos Location of cursor in this buffer. This is used to indicate what part of the string should be kept and what part should be advanced to the next match if any.
maxResultLength Maximum amount of result data to put into inputBuffer. This is capped by MaxCompletionBufferSize.
forwardTab Should we go forward to next match or backwards to previous match? True indicates forward.

bool Con::addVariable (  const char *  name,
S32  type,
void *  pointer
) 
 

Add a console variable that references the value of a variable in C++ code.

If a value is assigned to the console variable the C++ variable is updated, and vice-versa.

Parameters:
name Global console variable name to create
type The type of the C++ variable; see the ConsoleDynamicTypes enum for a complete list.
pointer Pointer to the variable.
See also:
ConsoleDynamicTypes

bool Con::removeVariable (  const char *  name  ) 
 

Remove a console variable.

Parameters:
name Global console variable name to remove
Returns:
true if variable existed before removal.

void Con::setLocalVariable (  const char *  name,
const char *  value
) 
 

Assign a string value to a locally scoped console variable.

Note:
The context of the variable is determined by gEvalState; that is, by the currently executing code.
Parameters:
name Local console variable name to set
value String value to assign to name

const char* Con::getLocalVariable (  const char *  name  ) 
 

Retrieve the string value to a locally scoped console variable.

Note:
The context of the variable is determined by gEvalState; that is, by the currently executing code.
Parameters:
name Local console variable name to get

void Con::setVariable (  const char *  name,
const char *  value
) 
 

const char* Con::getVariable (  const char *  name  ) 
 

Retrieve the string value of a global console variable.

Parameters:
name Global Console variable name to query
Returns:
The string value of the variable or "" if the variable does not exist.

void Con::setBoolVariable (  const char *  name,
bool  var
) 
 

Same as setVariable(), but for bools.

bool Con::getBoolVariable (  const char *  name,
bool  def = false
) 
 

Same as getVariable(), but for bools.
