Naming your Terminal tabs in OSX Lion

If you find yourself in the Terminal app with a bunch of tabs open, the default name of “bash” isn’t very useful when navigating between them. You can change the tab name via the UI by right clicking the tab, then clicking “Inspect Tab” and changing the window or tab names but this is somewhat long winded.

Below are a couple of bash functions I have in my “.profile” file to make this easier:

function tabname {
  printf "\e]1;$1\a"
}
 
function winname {
  printf "\e]2;$1\a"
}

Now you can easily name your tabs or windows with the following:

# Rename tab
tabname "Funky Tab"
 
# Rename window
winname "Funky Window"

Thanks to Bubu and Chris Page on the SuperUser site for the right codes.

Using Pow when developing Rails applications on OSX

I heard about Pow a while ago which is “a zero-config Rack server for Mac OS X” but never got around to giving it a go. I’ve just installed it and can instantly see that it is going to make developing with Rails (or any Rack app) a whole lot nicer, especially when dealing with apps that use subdomain account keys.

If you’ve not tried it yet, head over to the Pow website and get it installed with:

curl get.pow.cx | sh

Happy new year everyone!

TextMate refusing to launch in Lion

On occasion under OSX Lion, TextMate refuses to launch. I’ve found that simply deleting it’s pid file seems to get things working again, just open Terminal and type:

rm ~/Library/Application\ Support/TextMate/TextMate.pid

Hope this safes someone some puzzled frowning time.

Ruby Causing MacBook Pro to Run Hot

The past couple of days the fan on my MacBook Pro has been constantly on and battery usage down to around a third. Launching Activity Monitor, it showed 3 Ruby processes all at 100% CPU usage. The solution was to force quit these processes and within seconds, the fan slowed up and the battery indicator went up. Force quitting these processes didn’t affect anything I was doing with Rails or IRB so I guess they were just stray processes.

If anyone else gets the same problem, just launch Activity Monitor which lives in the /Applications/Utilities folder, click the CPU tab if not already selected, select processes with a process name of “ruby”, click “Quit Process” and then select “Force Quit”. Just selecting “Quit” wouldn’t work for me hence the “Force Quit”.

I hope this saves someone else the head-scratching as to why their Mac is running hot.

Divvy – A great way to keep your windows organised in OSX

I’ve just come across a great little app for organising windows in OSX. It takes a different approach to your usual snapping system by giving you a grid via a HUD (heads up display) to select how much area you want a window take up.

Building Ruby, Rails, Subversion, Mongrel, and MySQL on Mac OS X Tiger – The Easy Way

“Dan Benjamin”:http://hivelogic.com/authors/danbenjamin recently updated his very helpful article entitled “”Building Ruby, Rails, Subversion, Mongrel, and MySQL on Mac OS X”:http://hivelogic.com/narrative/articles/ruby-rails-mongrel-mysql-osx”.

I don’t know about anyone else but compiling software is not one of my favourite pastimes. As I’ve been chopping and changing macs lately I thought I’d write a couple of shell scripts to get things right before running anything on my nice new (freshly installed) MacBook Pro.

h3. Prerequisites

There are a couple of prerequisites in addition to what’s on Dan’s “”What’s Needed”:http://hivelogic.com/narrative/articles/ruby-rails-mongrel-mysql-osx” list before running “the scripts”:http://svn.soniciq.com/public/rails/tools/osx_development_setup/. The first is that you must have MySQL installed as referenced in “Dan’s article”:http://hivelogic.com/narrative/articles/ruby-rails-mongrel-mysql-osx, and the second being the following:

Ensure you have the following line at the end of your ~/.bash_login file:

export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH"

You can add this by typing nano ~/.bash_login then copy and paste the above line into the end of the file. Once this is done, hit ctrl-x to exit, answering ‘y’ to “do you want to save changes” prompt.

h3. The scripts

There are two scripts, “01_osx_rails.sh”:http://svn.soniciq.com/public/rails/tools/osx_development_setup/01_osx_rails.sh and “02_osx_image_tools.sh”:http://svn.soniciq.com/public/rails/tools/osx_development_setup/02_osx_image_tools.sh and the following will explain how to use them.

h3. Creating your development environment

The first script will install everything in Dan’s article along with the following gems that I use frequently:
* rails version 1.1.6 for support of older rails apps
* bluecloth
* redcloth
* sqlite3-ruby
* ferret
* ZenTest
* redgreen

Right… here we go:

(please read “the licence”:http://svn.soniciq.com/public/rails/tools/osx_development_setup/MIT-LICENCE before running these scripts as although they have been tested on a clean install of Tiger, I can’t take any responsibility if something breaks)
# Download “01_osx_rails.sh”:http://svn.soniciq.com/public/rails/tools/osx_development_setup/01_osx_rails.sh to your desktop
# If you don’t wish to install all of these gems then open the file in a text editor and comment out the relevant lines with a hash.
# Open a new terminal window and type the following: 

cd ~/Desktop
sh 01_osx_rails.sh


# Go make a cup of tea and watch all the pretty text scroll before your eyes.

That’s it, you should now have a fully working development environment.

h3. Image tools

I use a couple of image tools on my system, GD and ImageMagick (with RMagick). If you wish to install these tools and the related libraries, run the following:

(This script hasn’t been tested as much as the previous one so use at your own risk. If anyone has any bug fixes then please post a comment)

cd ~/Desktop
sh 02_osx_image_tools.sh

h3. We’re done

Please let me know if I’ve missed anything obvious.

I hope this helps anyone else out there with Compilaphobia!
