Does the Joomla framework provide functionality to programmers to install an extension from another extension? I mean a full joomla extension and not an extension to a component (such as a plugin for a particular component).
The purpose is to create an update tool that checks versions and updates extensions. It would be particularly handy for managing multiple websites.
A similar extension is the Admin Tools component from Akeeba. It can check for updates, and do the updates on Joomla. It's not GPL so I probably am not allowed to enhance their component with the desired functionality and then use it commercially, but that's for later concern.
Any suggestions or thought directions? =]
To my knowledge I don't think they provide the functionality, however you should be free to download files with fopen/curl and copy them all over the place as you want. Joomla also doesn't check if where you copy files is actually within a specific component space.
On GPL and commercial, there is no link between commercial and GPL - you just have to distribute the source code whenever you distribute, even if you charge for it or the access. This means everyone down the chain is free to pass your code on for free.

I have been developing websites for some years. I know PHP. but I have never worked with a CMS before. I've been told to create a website with Joomla where there's a homepage and also new users may sign up and then they can have a profile page where they can upload their profile picture and write their résumé.
This is easy for me to implement this system if I start coding it by myself. but how can I do this in Joomla? is there a plug-in which I need? could someone please give me some resources?
No need to re-invent the wheel - there are tons of ready-built components at the Extensions Directory. Last I checked Community Builder and JomSocial were the most popular, but they might be overkill for your need, so it's worth having a look at the other choices there. If you're new to Joomla, you're probably interested in a Component, which is essentially a "sub-application" that installs under Joomla. They usually include Modules that can be displayed on the site, as well as Plugins that work with the core Joomla logic to perform specialized functions for the installed component.
There are many plugins, but the simple functionality of user profiles is implemented in Joomla. This question might help you.
I am user of Joomla 2.5 cms and I try to built a double-language site.
Yesterday I installed this one module to my site
http://extensions.joomla.org/extensions/access-a-security/site-access/authentication-management/6660
but this don't support 2 languages, only one.
The help I need is some information on how I can add new files for this module with new labels of course at my excisting language packages.
if it doesn't support 2 languages, you have some problems
anyway you can ask your developer to help you.
or you can check the source and change the needed words to your desire language, then you can change the module name and install it separately
it is important to see if you have the right to change that extension.
and you can write your own of course :)
I have been learning to develop my own plugins and components for joomla! 2.5.
After a couple of months of developing features for my site, I am starting to realise that some of the components I have created could have probably been just as effective if I'd developed them as a plugin for com_content or com_user.
My question is what's the best way to decided if a full component is needed and when is it ok to use one or multiple plugins to give the same functionality.
My feeling at the moment is that plugins are a much nicer way to go due to them being self contained. Maybe I've answered my own question, and components are needed when interaction between elements is more complicated, where as plugins can be used for very modular functions.
Anyone else have a view?
Components and Plugins are completely different types of extensions.
Components are applications/systems that will appear in the content area such as VirtueMart and where the articles are shown. Consider them as software for you computer.
Plugins are there to manipulate Joomla and/or there extensions it's using. They contains functions that are associated with trigger events. So in a nutshell, they are there to extend the functionality of an existing extension.
So so answer your question, have a think about what you are creating and if will be an aplication or something to extend functionality.
Hope this helps
I had an issues with some joomla api. The issue was that I was using the latest version of joomla and couldn't find where a joomla class, that was being called in my code, was derived . I searched the joomla api docs and found nothing relating to the class I was looking for.
I then stumbled across the refactoring change log for joomla and noticed that the function i was after had actually been moved from /libraries/joomla/form to libraries/cms/form.
Why would this be the case? There doesn't seem to be any reference to /libraries/cms in the api docs. How are we suppose to know that there are classes living there? Very confusing.
Since Joomla! 1.6 the code has been progressively split into the Joomla! CMS and the Joomla! Platform. You can see this separation in the github repository - a good place to also keep track of changes that are committed to both the CMS and the Platform. The simplest way is fork each repository and keep track of them.
As classes are updated they may be migrated to the /libraries/cms directory if they apply specifically to the CMS application (e.g. html forms are an application level function not a platform level).
I find the best place to hear about changes under discussion are in the respective Google Groups - Joomla! Platform Development and Joomla! CMS Development
[Edit]
Documentation of class's is the hardest thing to find for Joomla! CMS - there doesn't appear to be a current api listing for it, unlike the Platform API reference. Often it is just easier to read through the code.
It's also worth keeping a watch on the developer sub-site.

I am new to open source Content Management System tools. I got a website using Joomla for content management. Now, I am just thinking to Umbraco or Dotnetnuke (any Asp.net based) frameworks to use. Will it be a complex to do this migration. Can you suggest pros and cons for this idea.
Any help is appreciated. Thanks !
For Umbraco ...
Most of your client-side code like HTML, CSS and JavaScript can just be copied straight over, but as expected it may require some fiddling.
As for the data, it might be worth looking into the CMSImport module for Umbraco. As long as you can convert the source data into one of the formats recognised by the module, you should be able to upload your content with ease. I've had no personal experience with this module, but should be worth a shot.
It really depends on the size of the site and the functionality requirements. For smaller sites, it may be as easy as implementing the skin based on the original design (or, if a custom design isn't needed, selecting a free or 3rd party skin) and then manually migrating the content. For really large sites, you should be able to write scripts to migrate the content. I'm not aware of any products that do this. You'll also probably need to select some modules to use for things like forms.
