Detailed Description

Handling the GUI of the in-game console.

Definition in file console_gui.cpp.

Function Documentation

IConsoleGUIPrint()

void IConsoleGUIPrint	(	TextColour	colour_code,
		const std::string &	str
	)

Handle the printing of text entered into the console or redirected there by any other means.

Text can be redirected to other clients in a network game as well as to a logfile. If the network server is a dedicated server, all activities are also logged. All lines to print are added to a temporary buffer which can be used as a history to print them onscreen

Parameters

colour_code	the colour of the command. Red in case of errors, etc.
str	the message entered or output on the console (notice, error, etc.)

Definition at line 448 of file console_gui.cpp.

References _iconsole_buffer, SetWindowDirty(), and WC_CONSOLE.

IConsoleHistoryAdd()

static const char * IConsoleHistoryAdd ( const char *  cmd )

static

Add the entered line into the history so you can look it back scroll, etc.

Put it to the beginning as it is the latest text

Parameters

cmd	Text to be entered into the 'history'

Returns

the command to execute

Definition at line 404 of file console_gui.cpp.

References IsWhitespace(), and StrEmpty().

IConsoleHistoryNavigate()

static void IConsoleHistoryNavigate ( int  direction )

static

Navigate Up/Down in the history of typed commands.

Parameters

direction

Go further back in history (+1), go to recently typed commands (-1)

Definition at line 427 of file console_gui.cpp.

IsValidConsoleColour()

bool IsValidConsoleColour

(

TextColour

c

)

Check whether the given TextColour is valid for console usage.

Parameters

c	The text colour to compare to.

Returns

true iff the TextColour is valid for console usage.

TruncateBuffer()

static bool TruncateBuffer ( )

static

Remove old lines from the backlog buffer.

The buffer is limited by a maximum size and a minimum age. Every time truncation runs, all lines in the buffer are aged by one. When a line exceeds both the maximum position and also the maximum age, it gets removed.

Returns

true if any lines were removed
