I recently wanted to see which parts of my app were using the most memory in a PHP script. I’ve been using Xdebug and webgrind on MAMP on my local machine and loving it. Derick Rethans wrote a post a few years ago about how to use Xdebug to profile memory usage and it was fairly easy to get it working.
TextMate recently released an update that changed one of my favorite keyboard shortcuts. This event reminded me that Mac OS X has provided a nice way to create your own keyboard shortcut key bindings. To create your own keyboard shortcut for an application, you will need to know the exact name given in the application’s menu.

I have been using the Kynetx KRL command line tool for several weeks now and it has made my development of Kynetx apps much easier. The only problem that I have had as I have been using the command line tool is that once I commit my app I have to wait a few seconds before being able to run the new version in my browser. Until now I have been doing a lot of command + tab switching between windows to check to see if it has finished saving.
I have now created a clean solution that allows me to know when the version has finished being committed to the Kynetx servers and had one unexpected benefit.
I started out by creating a simple bash alias that would pipe the output from the ‘krl commit’ command to a growl notification
# Growl notify after krl commit is done
alias krlc="krl commit | growlnotify -t "KRL" --image /Users/mikegrace/src/kynetx-x.png;"
I quickly realized that this wouldn’t work for me because piping the console to the growl notification means that the commit output wouldn’t be visible on the console. I need to be able to see on the console what the output was in case there were errors or the latest saved version so I started looking for a better solution and came up with this
# Use growlnotify to alert user of commit status
if [[ $@ == "commit" ]]; then
command krl commit | tee status.txt | growlnotify -t "KRL" --image /kynetx-x.png;
command krl $@
I created a function in my bash profile that runs when I run the krl command. When it sees me using the commit parameter it will do a krl commit and then tee that output to a status.txt file and pipe it to the growl notification. To have the output also show up on the console I cat the status.txt file back to the console. The unforeseen benefit here is that it is now really easy to share error output with others because it can be found in the status.txt file in the app folder.
I also created a bash script, available on my github, that takes care of the installation for you. I created this script purely for fun and I had a blast doing it!
I had a really great time doing all of this and learned a lot. There is a lot of power in being able to manipulate command line tools to make tasks easier.
