3.36.1 Goals

5fb024
ec5f63

The <tt>`trunk/Scripts/Bash'</tt> directory exists to organize the trunk

ec5f63
development line of <tt>`centos-art.sh'</tt> automation script.  The
ec5f63
<tt>`centos-art.sh'</tt> script standardizes frequent tasks inside your
ec5f63
working copy of CentOS Artwork Repository.

3.36.2 Description

5fb024
ec5f63

The best way to understand <tt>`centos-art.sh'</tt> automation script is

ec5f63
studying its source code.  However, as start point, you may prefer to
ec5f63
read an introductory resume before diving into the source code
ec5f63
details.
ec5f63

ec5f63

The <tt>`centos-art.sh'</tt> script is written in Bash. Most tasks, inside

ec5f63
<tt>`centos-art.sh'</tt> script, have been organized in many specific
ec5f63
functionalities that you can invoke from the centos-art
ec5f63
command-line interface.
ec5f63

ec5f63

When you type the centos-art command in your terminal, the

ec5f63
operating system trys to execute that command. In order to execute the
ec5f63
command, the operating system needs to know where it is, so the
ec5f63
operating system uses the PATH environment variable to look for
8e85aa
that command location. If your system was prepared to use CentOS
13b177
Artwork Repository correctly (see section trunk/Scripts/Bash/Functions/Verify), you should have a symbolic link inside <tt>`~/bin/'</tt>
ec5f63
directory that points to the <tt>`centos-art.sh'</tt> script file. As
ec5f63
<tt>`~/bin/'</tt> directory is, by default, inside PATH environment
ec5f63
variable, the execution of centos-art command runs the
ec5f63
<tt>`centos-art.sh'</tt> script.
ec5f63

ec5f63

When <tt>`centos-art.sh'</tt> script is executed, the first it does is

ec5f63
executing the <tt>`trunk/Scripts/Bash/initEnvironment.sh'</tt> script to
8e85aa
initialize global variables (e.g., gettext variables) and
ec5f63
global function scripts.  Global function scripts are located inside
ec5f63
<tt>`trunk/Scripts/Bash/Functions'</tt> directory and their file names
ec5f63
begin with <samp>`cli'</samp>. Global function scripts provide common
ec5f63
functionalities that can be used anywhere inside <tt>`centos-art.sh'</tt>
ec5f63
script execution environment.
ec5f63

ec5f63

Once global variables and function scripts have been loaded,

ec5f63
<tt>`centos-art.sh'</tt> script executes the cli global function
ec5f63
from <tt>`cli.sh'</tt> function script to retrive command-line arguments
ec5f63
and define some default values that may be used later by specific
5cee2c
function scripts (see section trunk/Scripts/Bash/Functions).
ec5f63

ec5f63

As convenction, the <tt>`centos-art.sh'</tt> command-line arguments have

ec5f63
the following format:
ec5f63

ec5f63
centos-art arg1 --arg2=val2 --arg3=val3
ec5f63
ec5f63

In the above example, <samp>`centos-art'</samp> is the command you use to

ec5f63
invoke <tt>`centos-art.sh'</tt> script. The <samp>`arg1'</samp> is required and
ec5f63
represents the functionality you want to perform (e.g.,
ec5f63
<samp>`verify'</samp>, <samp>`render'</samp>, <samp>`locale'</samp>, <samp>`manual'</samp>,
ec5f63
etc.). The remaining arguments are modifiers to <samp>`arg1'</samp>. The
ec5f63
<samp>`--arg2'</samp> definition is required and represets, specifically,
ec5f63
the action inside the functionality you want to perform.  The
ec5f63
<samp>`--arg3'</samp> and on, are optional.
ec5f63

ec5f63

Once command-line arguments have been retrived, the

ec5f63
<tt>`centos-art.sh'</tt> script loads specific functionalities using the
ec5f63
<tt>`cli_getFunctions.sh'</tt> function script. Only one specific
ec5f63
functionality can be loaded at one script execution I.e., you run
ec5f63
centos-art.sh script to run just one functionality.

Functionalities are implemented by means of actions. Once the

ec5f63
functionality has been initiazalized, actions initialization take
ec5f63
place for that functionality. Actions initialization model is very
ec5f63
similar to functions initialization model. But with the difference,
ec5f63
that actions are loaded inside function environment, and so, share
ec5f63
variables and functions defined inside function environment.
