My shortcut to open any gem in TextMate with 1 command

Thu, 10 Dec 2009 12:42:13 +1100

Using the implementation from @peepcode’s blog on shell method missing as a base.

I’ve added another action (code snippet below) to open a gem library in TextMate by typing in the name of the gem followed by “.mate”.

when /^[A-Za-z0-9_-\/]+.mate$/

# Open the gem in textmate

# @example

# haml.mate

gem_to_open = command.first.gsub(/.mate$/, ”)

run “gem which #{gem_to_open} | tail -1 | xargs dirname | sed -e’s/$/\/../’ | xargs mate”

Download sources jar from maven

Thu, 26 Nov 2009 17:05:42 +1100

We use Maven, when Maven downloads dependencies it doesn’t download sources, which I rely on when learn and debug programs….
I was expecting, for what seem a simple thing to me, a flag that I can add in maven’s settings files or an option to pass to mvn command…. but I couldn’t find the solution (or anything close to it). Don’t get me wrong, there are solutions out there, but I just feel it is too much hassle for the task. So I wrote a little script that go thru my repo and downloads any jar that doesn’t have its respective sources :p

ImageMagick and JPEG on OSX

Tue, 24 Nov 2009 11:52:00 +1100

I am not a fan of port or fink so I always install ImageMagick from source.

Recently I came across a problem where ImageMagick fails to identify JPEG’s.

The error looks something like this

identify: no decode delegate for this image format

After some digging around it appears I need to install libjpeg and reinstall ImageMagick for JPEG support.

So I downloaded jpegsrc.v7.tar.gz and just run thru the standard configure, make & make install then reinstalled ImageMagick.

After the installation you should be able to see JPEG as one of the supported format via the command ”identify -list format”.

It should contain something like this.

JPEG* JPEG rw- Joint Photographic Experts Group JFIF format (70)

This is a reminder for myself more than anything.

To learn what you can do with an application using osascript, you can run Script Editor and click “Open the Application’s Dictionary” to see properties &/methods that are available.

Jar decompiler

Sat, 05 Jul 2008 16:11:11 +1000

A while ago I posted some shell scripts to decompile java classes.

I decided to re-implement it in ruby so I can use it between my work (Windows) and home (OS X) machines.

This version does not require you to extract the class files first. You simply pass the jar file to the script and it’ll decompress and decompile it into a directory with the same name as the jar file without .jar.

How to decompile everything

Fri, 13 Jun 2008 21:30:05 +1000

Quick script to decompile all the class files.

find . -name "*.class" -not -name "*\$*" | while read class
do
  dir=`dirname $class`
  file=`basename $class .class`
  pushd $dir >/dev/null
  jad -p ${file}.class > ${file}.java
  popd >/dev/null
done

OS X's ruby framework

Thu, 05 Jun 2008 23:15:00 +1000

I think new version of ruby is meant to be installed with the following prefix, using 1.8.7 as an example.

/System/Library/Frameworks/Ruby.framework/Versions/1.8.7/usr

That way you can just /System/Library/Frameworks/Ruby.framework/Versions/Current to the version you want.

How to revert back to os x ruby framework

Thu, 05 Jun 2008 23:10:21 +1000

As I mentioned before, I upgraded to ruby 1.8.7 and decided to use —prefix=/usr, i.e. overwriting existing ruby 1.8.6. Big mistake. After some issues I decided to roll back completely.

This is what I did (luckily I can copy the required files from my wife’s Macbook).

OS X ruby framework overview

The framework is /System/Library/Frameworks/Ruby.framework

/usr/lib/ruby is a softlink to osx ruby framework
osx ruby framework’s site_ruby is a softlinke to /Library/Ruby/Site

To fix

/usr/bin
osx ruby framework
/Library/Ruby/Site

Actions

Rename the following directories then copy the same directories from another OS X

/System/Library/Frameworks/Ruby.framework
/Library/Ruby/Site

Make sure the following files are links to os x ruby framework’s /usr/bin

/usr/bin/erb
/usr/bin/irb
/usr/bin/rdoc
/usr/bin/ri
/usr/bin/ruby
/usr/bin/testrb

Cleanup

Remove these backup directories afterwards (once everything is ok)

os x ruby framework .bak
/Library/Ruby/Site.bak
/usr/lib/ruby/site_ruby.bak
/usr/lib/ruby/user-gems.bak

Now

link /usr/lib/ruby/site_ruby to /Library/Ruby/Site
link /usr/lib/ruby/user-gems to /Library/Ruby/Gems

I give this 2 thumbs up :p
