Redirecting NSLog with NSLogConsole

UPDATE check out Redirecting NSLog to a file for just capturing NSLog.

NSLogConsole captures NSLog data (from stderr) and redirects it to a console. It still forwards it to XCode's and also appears in Console.app. I've redirected to an html console, but you can do pretty much anything with the data : save it to a file, mail it, discard it, filter it …

Sample code

Usage

Copy NSLogConsole.(m h html xib) in your project
Add #define NSLog(args...) NSLog(args), NSLogPostLog(__FILE__, __LINE__) to your project's precompiled header
Start it with [NSLogConsole sharedConsole] to capture messages, open it with [[NSLogConsole sharedConsole] open]

MIT license. Use freely !

Right now, launching from the Finder blocks on reading … works fine in XCode and Terminal. So don't use in production code :) Somehow stderr doesn't behave the same from Finder and from XCode. Any ideas ?

Thanks for this wonderful peace of code. While testing I found that -init of NSLogConsole is called twice: 1st by NIB-Loader and 2nd by -sharedConsole.

Thx,first.

I run your code, in my prj. Some error comes up for webview didnot load html file before invoking it.

So I add some code below:

In -[logData:file:lineNumber:]

if (![webView isWebViewLoaded]) {

   return;

}

In NSLogConsoleView - (BOOL)isWebViewLoaded;
