* Introduction
Freedombone consists of a set of bash scripts. There are a lot of them, but they're not very complicated. If you're familiar with the GNU/Linux commandline and can hack a bash script then you can probably add a new app or fix a bug in the system. There are no trendy development frameworks to learn or to get in your way. You might also want to consult the [[./codeofconduct.html][Code of Conduct]].

There are no trendy development frameworks to learn or to get in your way. You might also want to consult the [[./codeofconduct.html][Code of Conduct]], and there is a Matrix room at *#fbone:matrix.freedombone.net*
* Adding extra apps
Suppose you have some internet application which you want to add to the system. To do this you need to create an app script which tells the system how to install/remove and also backup/restore. The script should be designed to work with the current stable version of Debian.
On an installed system the app scripts go into the directory:
There's a command which you can use to generate scripts for new apps. Some examples are as follows:
To create a script for a generic PHP plus MySql/MariaDB web app:
#+begin_src bash
/usr/share/freedombone/apps
freedombone-template --app [name] -e [email] -r [repo url] \
-c [commit] --php yes -d mariadb > \
src/freedombone-app-myappname
#+end_src
and within the project repo they appear within the /src/ directory. Your new app script should have the name:
For a Nodejs app with MySql/MariaDB database:
#+begin_src bash
freedombone-app-[myappname]
freedombone-template --app [name] -e [email] -r [repo url] \
-c [commit] --node yes -d mariadb \
--dir /etc/myappname --daemon yes > \
src/freedombone-app-myappname
#+end_src
The /myappname/ value should not contain any spaces and will appear in the list of available apps.
An example template for an app script is shown below. Copy this and add whatever variables and configuration you need. Search and replace /myappname/ with your own.
For a Python app with Postgresql database:
#+begin_src bash

To test your app log into your system, select *Exit to command line* then gain root powers with:
For a Python app without any database, communicating between the daemon and the web server on port 1234:
#+begin_src bash
sudo su
freedombone-template --app [name] -e [email] -r [repo url] \
-c [commit] --dir /etc/myappname \
--daemon yes --portinternal 1234 > \
src/freedombone-app-myappname
#+end_src
Copy your app script to */usr/share/freedombone/apps/freedombone-app-myappname*.
And run the admin control panel:
For an app without any database which communicates directly on a particular port through the firewall:
#+begin_src bash
control
freedombone-template --app [name] -e [email] -r [repo url] \
-c [commit] --dir /etc/myappname \
--daemon yes --port 5000 > \
src/freedombone-app-myappname
#+end_src
Select *Add/Remove Apps* and if all is well then you should see your app listed as installable. Test that installing and removing it works as expected.
A generic PHP plus MySql/MariaDB web app which is only available on an onion address:
Submit your working app to *https://github.com/bashrc/freedombone/issues*
#+begin_src bash
freedombone-template --app [name] -e [email] -r [repo url] \
-c [commit] --php yes -d mariadb \
--onion yes > \
src/freedombone-app-myappname
#+end_src
For more details see the manpage:
#+begin_src bash
man freedombone-template
#+end_src
The template command won't give you a fully working app, but it will give you a big head start and avoid a lot of potential mistakes. It's highly likely that you'll still need to add extra configuration for your particular app, especially within the *install_app* function.
When your new script is ready for testing you can install it with:
#+begin_src bash
make install
#+end_src
Then run the administrator control panel and you should see the new app within *Add/Remove apps*.
Submit your working app to *https://github.com/bashrc/freedombone/issues* or create a pull request.
* Customising mesh images
If you want to make your own specially branded version of the mesh images, such as for a particular event, then to change the default desktop backgrounds edit the images within *img/backgrounds* and to change the available avatars and desktop icons edit the images within *img/avatars*. Re-create disk images using the instructions shown previously.

Freedombone consists of a set of bash scripts. There are a lot of them, but they're not very complicated. If you're familiar with the GNU/Linux commandline and can hack a bash script then you can probably add a new app or fix a bug in the system. There are no trendy development frameworks to learn or to get in your way. You might also want to consult the <a href="./codeofconduct.html">Code of Conduct</a>.

Suppose you have some internet application which you want to add to the system. To do this you need to create an app script which tells the system how to install/remove and also backup/restore. The script should be designed to work with the current stable version of Debian.
</p>
<p>
On an installed system the app scripts go into the directory:
There's a command which you can use to generate scripts for new apps. Some examples are as follows:
</p>
<p>
To create a script for a generic PHP plus MySql/MariaDB web app:
</p>
<div class="org-src-container">
<pre class="src src-bash">/usr/share/freedombone/apps
<pre class="src src-bash">freedombone-template --app [name] -e [email] -r [repo url] <span class="org-sh-escaped-newline">\</span>
-c [commit] --php yes -d mariadb &gt; <span class="org-sh-escaped-newline">\</span>
src/freedombone-app-myappname
</pre>
</div>
<p>
and within the project repo they appear within the <i>src</i> directory. Your new app script should have the name:
For a Nodejs app with MySql/MariaDB database:
</p>
<div class="org-src-container">
<pre class="src src-bash">freedombone-app-[myappname]
<pre class="src src-bash">freedombone-template --app [name] -e [email] -r [repo url] <span class="org-sh-escaped-newline">\</span>
-c [commit] --node yes -d mariadb <span class="org-sh-escaped-newline">\</span>
--dir /etc/myappname --daemon yes &gt; <span class="org-sh-escaped-newline">\</span>
src/freedombone-app-myappname
</pre>
</div>
<p>
The <i>myappname</i> value should not contain any spaces and will appear in the list of available apps.
</p>
<p>
An example template for an app script is shown below. Copy this and add whatever variables and configuration you need. Search and replace <i>myappname</i> with your own.
For a Python app with Postgresql database:

<pre class="src src-bash">man freedombone-template

<p>
The template command won't give you a fully working app, but it will give you a big head start and avoid a lot of potential mistakes. It's highly likely that you'll still need to add extra configuration for your particular app, especially within the <b>install_app</b> function.

Submit your working app to <b><a href="https://github.com/bashrc/freedombone/issues">https://github.com/bashrc/freedombone/issues</a></b>
When your new script is ready for testing you can install it with:
</p>
<div class="org-src-container">
<pre class="src src-bash">make install
</pre>
</div>
<p>
Then run the administrator control panel and you should see the new app within <b>Add/Remove apps</b>.
