My current project has a neat trick we picked up where the build has a red or green banner at the end when you run it locally to give good feedback about the build status. I’m not sure who originated it, but thanks!

I just had to tweak it a bit to get it working on OS X so I thought I would document the trick here.

run.sh - OS X

CMD=”./tools/ant/bin/ant -lib ./asl/lib/jdepend $@”
echo “Running command [${CMD}] …”
$CMD
if [ "$?" -ne 0 ]; then
    echo -e “`tput setab 1`  `cat ./ci/failed.txt` `tput setab 0`”
    exit 1
else
    echo -e “`tput setab 2`  `cat ./ci/passed.txt`  `tput setab 0`”
    exit 0
fi

This assumes you have two supporting files ./ci/passed.txt and ./ci/failed.txt which contain the message. You can generate messages to your taste here.

I have provided the files in this example here :

passed.txt

failed.txt

It has also been run under Ubuntu where the following works (it didnt work on OS X which is why I adapted it), but the tput should also work on Ubuntu. I’ve not explicitly tested this one!

if [ "$?" -ne 0 ]; then
    echo -e “\E[30;41m"
    cat ./ci/failed.txt
    echo -e "\E[0m"
    exit 1
else
    echo -e "\E[30;42m"
    cat ./ci/passed.txt
    echo -e "\E[0m"
    exit 0
fi

Under windows you can actually make the entire screen of the terminal change color:

run.bat - WINDOWS

CALL tools\ant\bin\ant %*
IF ERRORLEVEL 1 GOTO RedBuild
IF ERRORLEVEL 0 GOTO GreenBuild
:RedBuild
color 4F
GOTO TheEnd
:GreenBuild
color 2F
:TheEnd
PAUSE
color 07

You can see the thread I found here

The downloads for both the JDK and the associated documentation live here login and go to downloads. You want “Java for Mac OS X Release X” and “Java for Mac OS X Release X Developer documentation”

It then lives in (e.g) /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home

I just discovered Exploding Pixels’ MacWidgets. Its a beautiful library. Literally just pasted a couple of lines of code into my Java app and now it looks right at home on the os x desktop. I’m running JDK 1.6 on Leopard.

Here is is in action:

And here is the code (its been edited slightly so may not copy and paste, but you get the idea) …

 
        MacUtils.makeWindowLeopardStyle(getRootPane());
 
        UnifiedToolBar toolBar = new UnifiedToolBar();
 
        JButton button = new JButton(“My Button”);
        button.putClientProperty(“JButton.buttonType”, “textured”);
        toolBar.addComponentToLeft(button);
 
        getContentPane().add(toolBar.getComponent(), BorderLayout.NORTH);
 
        BottomBar bottomBar = new BottomBar(BottomBarSize.SMALL);
        bottomBar.addComponentToLeft(MacWidgetFactory.createEmphasizedLabel(” Status”));
 
        getContentPane().add(bottomBar.getComponent(), BorderLayout.SOUTH);
 

A bit tired of trying to remember which tab is on which server with the default os x terminal ?

So was I. Hunting around, I saw various hacks (e.g. a bash script, or applescript) to achieve this but also an app called iTerm.

Its free and within 30mins I was pretty much back to my previous terminal existence but with the names of my servers and my username in the tabs titles.

Awesome.

Some things I learned:

1) Some of the preferences I had to hunt for:

Not everything is available from iTerm–>Preferences. There are a couple of menu options of interest (this is iTerm 0.9.6).

View–>Show Session Info …

This lets you change the colors and fonts, etc for your terminal window and also update the default.

Bookmarks –> Manage Profiles …

This is where you can set a lot more options about your session, including making the cursor blink (Something for some reason I found essential:)

The reason they are here is because they are associated with bookmarks, a powerful feature that for example allows you to bookmark an ssh session, and have a whole set of preferences associated with that session.

I would like to see them all aggregated under the “Preferences” option though, because as a os x user, thats where I expect to find everything that I can configure (Posted as an feature request.

2) I wanted the title to change whenever I change directory. Simple, just need the following in my ~/.bash_profile (see here for differences between ~/.bashrc:

export PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME%%.*}: ${PWD/#$HOME/~}\007"'

3) This one is not probably very “good form”, but I really like the icon for the os x terminal window. So simply “Show Package Contents” on the iTerm.app and swap out /Contents/Resources/iTerm.icns with the equivalent in the Terminal application Terminal.icns

4) I also wanted a “close x” icon on each tab, and discovered that this is under Preferences –> Tab –> Use compact tab labels. You want to UN check this.

I now have exactly the same user experience as before with some great bonuses, for example, a cool feature is the “blur” of the transparency behind the window.

Thanks to my colleague Tom Czarniecki I have found a solution that appears to be working.

Some googling turned up very little, but mostly points to the JVM being the problem. I had tried updating the Java installed on os x and setting the JDK to be 1.5 which did seem to improve stability but still crashed.

Tom pointed out that Intellij also has a configuration for the JDK version in its config which I updated to be 1.6+ and then switched my JDK back to 1.6 64bit. That was a week ago and not only have I had no crashes, of course the whole experience is smoother under 1.6! woo hoo!

The trick lies in the file

/Applications/IntelliJ IDEA 8.1.3.app/Contents/Info.plist

<key>JVMVersion</key>
<string>1.6*</string>

To Switch JDKs:

/Applications/Utilities/Java/Java Preferences.app

Some other references I found along the way:

http://www.jetbrains.net/devnet/thread/282406

JDK Update:

http://www.apple.com/downloads/macosx/apple/application_updates/javaformacosx105update4.html

To See IntelliJ Log output:

~/Library/Caches/IntelliJIDEA8x/log/

UPDATE:

For Intellij9:

/Users/jim/Library/Logs/IntelliJIdea90/idea.log

(I found this using the activity monitor and then “inspect process” and you can see a list of open files and ports)

IntelliJ stores its plugins here (Thanks to these guys) :

~/Library/Application Support/IntelliJIDEA80

I love this utility which copies the whole of your folders, including permissions and hidden system files.

The standard copy in finder often balks at some things.

Enjoy.

Before starting i uninstalled the mono i had already:

#!/bin/sh -x
#This script removes Mono from an OS X System.  It must be run as root
rm -r /Library/Frameworks/Mono.framework
rm -r /Library/Receipts/MonoFramework-SVN.pkg
cd /usr/bin
for i in `ls -al | grep Mono | awk '{print $9}'`; do
rm ${i}
done

First i could search for the mono package by typing

$ port search mono

To begin with this did not show the right version so i did :

$ port selfupdate

This checks for a new version of port and updates its list of available software.

now i see:

coco:~ Jim$ port search mono
mono                           devel/mono     2.0          Implementation of the .NET Development Framework
mono-addins                    devel/mono-addins 0.3          Mono.Addins is a framework for creating extensible applications
monodoc                        devel/monodoc  2.0          Documentation for the Mono .NET Development Framework
monotone                       devel/monotone 0.41         A distributed version control system
mod_mono                       www/mod_mono   1.1.16.1     an Apache plug-in for hosting the Mono System.Web classes
coco:~ Jim$

so all good, i ran

port install mono

but get :

darwin_stop_world.c:307: error: 'ppc_thread_state_t' has no member named '__r31'
make[3]: *** [darwin_stop_world.lo] Error 1
make[2]: *** [all-recursive] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

A quick search on google brought this:

http://lists.macosforge.org/pipermail/macports-tickets/2008-February/005279.html

The instructions here talk about editing this darwin_stop_world.c file and changing some constant values. They give the path to the file for an older version but a bit of ls ing turned up the new folder:

/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_devel_mono/work/mono-2.0/libgc/darwin_stop_world.c

Ok, so now the tricksy bit…

The instructions in the above link talk about some constants not set up correctly. On the line wher ei saw my exception, it was referring to the following bit of code:

#elif defined(POWERPC)
#if defined(_STRUCT_PPC_EXCEPTION_STATE)
	lo = (void*)(state.__r1 - PPC_RED_ZONE_SIZE);

	GC_push_one(state.__r0);
	GC_push_one(state.__r2);
	GC_push_one(state.__r3);
	GC_push_one(state.__r4);
	GC_push_one(state.__r5);
	GC_push_one(state.__r6);
	GC_push_one(state.__r7);
	GC_push_one(state.__r8);
	GC_push_one(state.__r9);
	GC_push_one(state.__r10);
	GC_push_one(state.__r11);
	GC_push_one(state.__r12);
	GC_push_one(state.__r13);
	GC_push_one(state.__r14);
	GC_push_one(state.__r15);
	GC_push_one(state.__r16);
	GC_push_one(state.__r17);
	GC_push_one(state.__r18);
	GC_push_one(state.__r19);
	GC_push_one(state.__r20);
	GC_push_one(state.__r21);
	GC_push_one(state.__r22);
	GC_push_one(state.__r23);
	GC_push_one(state.__r24);
	GC_push_one(state.__r25);
	GC_push_one(state.__r26);
	GC_push_one(state.__r27);
	GC_push_one(state.__r28);
	GC_push_one(state.__r29);
	GC_push_one(state.__r30);
	GC_push_one(state.__r31);
#else

in the post, he seemed to simply remove all the ‘__’ underscores and it worked… so:

	#if defined(_STRUCT_PPC_EXCEPTION_STATE)
		lo = (void*)(state.r1 - PPC_RED_ZONE_SIZE);

		GC_push_one(state.r0);
		GC_push_one(state.r2);
		GC_push_one(state.r3);
		GC_push_one(state.r4);
		GC_push_one(state.r5);
		GC_push_one(state.r6);
		GC_push_one(state.r7);
		GC_push_one(state.r8);
		GC_push_one(state.r9);
		GC_push_one(state.r10);
		GC_push_one(state.r11);
		GC_push_one(state.r12);
		GC_push_one(state.r13);
		GC_push_one(state.r14);
		GC_push_one(state.r15);
		GC_push_one(state.r16);
		GC_push_one(state.r17);
		GC_push_one(state.r18);
		GC_push_one(state.r19);
		GC_push_one(state.r20);
		GC_push_one(state.r21);
		GC_push_one(state.r22);
		GC_push_one(state.r23);
		GC_push_one(state.r24);
		GC_push_one(state.r25);
		GC_push_one(state.r26);
		GC_push_one(state.r27);
		GC_push_one(state.r28);
		GC_push_one(state.r29);
		GC_push_one(state.r30);
		GC_push_one(state.r31);
	#else

This was defined on lines 130 and 273

the second one now looks like :

	
		#if defined(_STRUCT_PPC_EXCEPTION_STATE)
			lo = (void*)(info.r1 - PPC_RED_ZONE_SIZE);
			hi = (ptr_t)FindTopOfStack(info.r1);

Watch out for the top of stack one! its an extra one.

ok this works!

I had to restart the terminal because it didnt seem to find the new programs – it still thought mcs lived in /usr/bin not /opt/local/bin which is where port puts it.

Now i can compile c# version 3.0!!

oh yeah, be sure to use gmcs to compile, not mcs which is the old one.

They all need to be held down after boot when the noise happens.

• Mouse down : eject media
• shift : disable login items
• cmd-v : show console
• cmd-s : single user mode
• c : boot from CD
