Command line productivity
Posted by Helmut Granda | Filed under Programming
There is nothing more rewarding than creating shortcuts for your daily work routines, and what better than when using the command line.
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
//Check one file from repository in SVN with a specific revision number
Posted by Helmut Granda | Filed under AS Burst
Problem
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
- 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.
- 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.
- svn update -r### file.fil

//AS3 Convert function name on the fly
Posted by Helmut Granda | Filed under AS Burst
Why would you want to do this? Not sure but a sample here:
- 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
- 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
ZendFramework FollowSymLinks or SymLinksIfOwnerMatch error in XAMPP
Posted by Helmut Granda | Filed under AS Burst
Problem:
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:
- Options +FollowSymLinks
ZendFramework .htaccess ships with the following as default:
- 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:
- 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]
Flash Builder: Changing BorderContainer color during runtime.
Posted by Helmut Granda | Filed under AS Burst
I got myself in a mess trying to change the background color of the component during runtime and after different trial and error finally I figured out that it had to do with this declaration:
- <s :backgroundFill>
</s><s :SolidColor color="#000000" id="defaultColor"></s>
Once removed I was able to use
- 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.

I just had to work on some "Splat" animation and this was great as reference. Too bad my animation had to be limited but good for future refence.
//WordPress Custom Type loop
Posted by Helmut Granda | Filed under WordPress
With the upcoming version of WordPress 3 (available in beta as of today) here is a tip of how to pull the custom types in the loop once you have created them.
- <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.
