I have tested the Ruby on Rails API within TextMate. Hover over any function and hit ctl+cmd+d and a little popup will give you a glimpse at the API docs. Seems like a nice alternative to ACK or the normal TextMate function lookup.

More information and installation instructions are available at Priit’s site http://www.priithaamer.com/blog

Here is a nice video of the tool

curl -O http://www.scala-lang.org/downloads/distrib/files/scala-2.7.6.final-installer.jar
sudo java -jar scala-2.7.6.final-installer.jar

This will launch an installer. Just follow the instructions and when it asks for the destination folder, remember that it’s in /usr/local/scala

This will fail

gem install mysql

What you need to do is tell the gem which MySQL to use. I installed MySQL with mac ports, http://macports.org , so I need to specify this when I run the installation command.

gem install mysql -- --with-mysql-config=/opt/local/lib/mysql5/bin/mysql_config

Check out an earlier post explaining how to install MySQL with mac ports http://seanbehan.com/programming/installing-sphinx-search-engine-on-mac-os-x-or-ld-library-not-found-for-lmysqlclient/

You’re not out of the woods yet. Rails needs to know the location of the socket it uses to connect to the MySQL server. I created a symbolic link to the location Rails normally looks for this socket. You could specify the location of the socket in the config/database.yml file, however, then you’ll need to do this with each of your applications.

ln -s /private/tmp/mysql.sock /opt/local/var/run/mysql5/mysqld.sock

If there is an easier way to get MySQL back for Rails on Mac OS X please let me know. I’d love a quick fix to this problem.

 ld: library not found for -lmysqlclient

There is a quick solution to the problem -upgrade mysql! You’ll need Mac Ports installed, available at

http://macports.org/

Run the command

sudo port install mysql5

This will not destroy any existing data from your previous MySQL installation. The mac port installation will take a while, and it will appear as if it is just hanging. It’s not. It just takes a while. I clocked it at 15 minutes on a relatively fast network connection. Drink a cappuccino!

After you have the upgrade you’ll need to download Sphinx available at:
http://sphinxsearch.com/downloads.html (latest stable) and build the Sphinx engine from source like so:

wget http://sphinxsearch.com/downloads/sphinx-0.9.8.1.tar.gz
tar xzvf sphinx-0.9.8.1.tar.gz
cd  sphinx-0.9.8.1/
./configure --with-mysql-libs=/opt/local/lib/mysql5/mysql/
--with-mysql-includes=/opt/local/include/mysql5/mysql/
make
sudo make install

Much thanks to this post b/c I spent forever trying to get the bundled version of MySQL linked properly:
