Can't read top of robot error message

[liq3 0]

My robot is outputting error messages that are so long I can't read the top, maybe debugging almost impossible. Is there anyway around this? Outputting the error to a file maybe?

In OpenOS 1.6 you can redirect the stderr buffer to file by appending 2>/path/to/file when running the command.

$ myprogram 2>/errors.log

Now when your program crashes, the error message will go to the /errors.log file.

That doesn't work for me. I'm running basic OpenOS.

If "basic OpenOS" means OpenOS 1.5, I strongly recommend you to update the mod (and reinstall the OS). In previous versions of the OS there's no easy way to redirect error messages.

It says OpenOS 1.6 when I boot the computers. The redirect doesn't work for me.

Oh, sorry. I was wrong. It can't redirect error() messages.

 

I wrote a simple program that writes error message to file when a program crashes. Run the following command to download it.

$ wget https://gist.githubusercontent.com/Fingercomp/6563c64d70a4472f26923f78d77caeb9/raw/aa4f461ddee2af70a8040065be8974069e240e27/crash.lua /usr/bin/crash.lua

Usage:

$ crash /crash.log /home/bin/program.lua arg1 arg2

/crash.log is the file where the crash will be written.

/home/bin/program.lua is the path to your program.

arg1 arg2 are arguments passed to the program.
