Log

A class for logging errors, warnings and information! Different levels of information can be filtered out, and supports coloration via <~[colorCode]> and <~clr> tags.

Text colors can be set with a tag, and reset back to default with <~clr>. Color codes are as follows:

Dark	Bright	Decription
DARK	BRIGHT	DESCRIPTION
blk	BLK	Black
red	RED	Red
grn	GRN	Green
ylw	YLW	Yellow
blu	BLU	Blue
mag	MAG	Magenta
cyn	cyn	Cyan
grn	GRN	Green
wht	WHT	White

Static Fields and Properties


LogLevel Filter	What’s the lowest level of severity logs to display on the console? Default is LogLevel.Info.

Static Methods


Err	Writes a formatted line to the log using a LogLevel.Error severity level!
Info	Writes a formatted line to the log using a LogLevel.Info severity level!
Subscribe	Allows you to listen in on log events! Any callback subscribed here will be called when something is logged. This does honor the Log.Filter, so filtered logs will not be received here.
Unsubscribe	If you subscribed to the log callback, you can unsubscribe that callback here!
Warn	Writes a formatted line to the log using a LogLevel.Warn severity level!
Write	Writes a formatted line to the log with the specified severity level!

Examples

Then you add the OnLog method into the log events like this in your initialization code!

Log.Subscribe(OnLog);

And in your Update loop, you can draw the window.

LogWindow();

And that’s it!

An in-application log window

Here’s an example of using the Log.Subscribe method to build a simple logging window. This can be pretty handy to have around somewhere in your application!

Here’s the code for the window, and log tracking.

static Pose         logPose = new Pose(0, -0.1f, 0.5f, Quat.LookDir(Vec3.Forward));
static List<string> logList = new List<string>();
static void OnLog(LogLevel level, string text)
{
	if (logList.Count > 10)
		logList.RemoveAt(logList.Count - 1);
	logList.Insert(0, text.Length < 100 ? text : text.Substring(0,100)+"...");
}
static void LogWindow()
{
	UI.WindowBegin("Log", ref logPose, new Vec2(40, 0) * U.cm);
	for (int i = 0; i < logList.Count; i++)
		UI.Label(logList[i], false);
	UI.WindowEnd();
}
