put the magic word 'debug infront of any command to generate a debug trace of everything cow is thinking during that command.
eg debug think how did I get here?
You will see a little link 'view log' appear at the bottom left of your browser window.
Click on it to see your debug log.
- You can refresh this after doing subsequent debugs without having to open it again in a new window.
Explanation of the mumbo-jumbo
Things are coloured to group them:
Blocks being run from objects are in maroon
Each command being executed is shown in blue
Logical thinking about processing this command is in black
SQL commands (effecting the database) are in green
So simply step from one maroon line to the next to see your blocks being executed... and read each blue line in between to see individual command.
