Problem:

You have to create a directory and then cd to it after creation.

Solution:

Open your blash_profile for editing, in my case I will use nano

$ nano ~/bash_profile

once open, now I can add the following function to it.

function mkcd()
{
mkdir -p $1 && eval cd $1
}

Almost there... now do control-x + enter + control-c, finally source blash_profile

$ source ~/.bash_profile

You are now set. next time you need to create a new directory and cd to it all you have to do is:

$ mkcd name_of_directory

You have to edit one file from a repository but there are hundreds of files in that repository with possible hundreds of MB or GB worth of information. Not only that but you might need the file on a specific revision number.

You have tried

PHP:
    svn checkout http://svn.source/directory/file.fil

But this doesn't work.

Solution

You need to check out an empty directory from repository and then apply an update to the file you need.

PHP:
    svn checkout --depth=empty htt://svn.source/directory[php]

    Now you submit the update command for the file you need checked out

    [php]svn update file.fil

note, before running the svn update make sure you "cd" to the directory that you just checked out from svn "cd /directory".

finally if you want the file to a specific revision number all you have to do is run an update again with the revision number.

PHP:
    svn update -r### file.fil

Not sure but a sample here:

ActionScript:
    var _x = 100;

    function a() : void
    {
       trace("\t\tCalled from A = _x" + _x + "\n");
       
    }

    var b = function (): void
    {
       trace("\t\tCalled from B \n");
    }

    trace("Do a regular B call\n");
    b();

    trace("Convert B to A\n");
    b = a;

    trace("B Converted\n");
    b();
    trace("Do a regular A call\n");
    a();

Result

ActionScript:
    Do a regular B call

          Called from B

    Convert B to A

    B Converted

          Called from A = _x100

    Do a regular A call

          Called from A = _x100

You may be getting a 403 error and if you look at the logs you should find something similar to the following:

[error] [client 127.0.0.1] Options FollowSymLinks or SymLinksIfOwnerMatch is off which implies that RewriteRule directive is forbidden: /Applications/xampp/xamppfiles/htdocs/project/public/index.php

Solution:

In your .htaccess file add the following line to the begining of the file:

PHP:
    Options +FollowSymLinks

ZendFramework .htaccess ships with the following as default:

PHP:
    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} -s [OR]
    RewriteCond %{REQUEST_FILENAME} -l [OR]
    RewriteCond %{REQUEST_FILENAME} -d
    RewriteRule ^.*$ - [NC,L]
    RewriteRule ^.*$ index.php [NC,L]

Adding the two lines above fixes the problem. So the file should look like this:

PHP:
    Options +FollowSymLinks
    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} -s [OR]
    RewriteCond %{REQUEST_FILENAME} -l [OR]
    RewriteCond %{REQUEST_FILENAME} -d
    RewriteRule ^.*$ - [NC,L]
    RewriteRule ^.*$ index.php [NC,L]

ActionScript:
    <s :backgroundFill>
       
       </s><s :SolidColor color="#000000" id="defaultColor"></s>
       

Once removed I was able to use

ActionScript:
    this.setStyle("backgroundColor",0x00afe1);

I don't really understand why having the backgroundFill declaration within the body of the component, it would affect the behavior to the point that I wasn't able to change the color of the object but when I find the explanation I will for sure post it here.

PHP:
    <h3>Recent News</h3>
    <ul>
    < ?php
        $recentPosts = new WP_Query();
        $recentPosts->query($query_string . '&post_type=news');
    ?>
    < ?php while ($recentPosts->have_posts()) : $recentPosts->the_post(); ?>
        <li><a href="<?php the_permalink() ?>" rel="bookmark">< ?php the_title(); ?></a></li>
    < ?php endwhile; ?>
    </ul>

In the example above I have created a "News" custom type and now I am adding them to the page with a custom loop.
