2.50.1 Goals

671838

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

671838
development line of <tt>`centos-art.sh'</tt> automation script.  The
671838
<tt>`centos-art.sh'</tt> script standardizes frequent tasks inside your
671838
working copy of CentOS Artwork Repository.

2.50.2 Description

b9dbd3
671838

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

671838
studying its source code.  However, as start point, you may prefer to
671838
read an introductory resume before diving into the source code
671838
details.
671838

671838

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

671838
<tt>`centos-art.sh'</tt> script, have been organized in many specific
671838
functionalities that you can invoke from the centos-art
671838
command-line interface.
671838

671838

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

671838
operating system trys to execute that command. In order to execute the
671838
command, the operating system needs to know where it is, so the
671838
operating system uses the PATH environment variable to look for
671838
that command location. If your system was prepared to use CentOS
671838
Artwork Repository correctly (-- Removed(pxref:trunk Scripts Bash Functions
671838
Verify) --), you should have a symbolic link inside <tt>`~/bin/'</tt>
671838
directory that points to the <tt>`centos-art.sh'</tt> script file. As
671838
<tt>`~/bin/'</tt> directory is, by default, inside PATH environment
671838
variable, the execution of centos-art command runs the
671838
<tt>`centos-art.sh'</tt> script.
671838

671838

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

671838
executing the <tt>`trunk/Scripts/Bash/initEnvironment.sh'</tt> script to
671838
initialize global variables (e.g., gettext variables) and
671838
global function scripts.  Global function scripts are located inside
671838
<tt>`trunk/Scripts/Bash/Functions'</tt> directory and their file names
671838
begin with <samp>`cli'</samp>. Global function scripts provide common
671838
functionalities that can be used anywhere inside <tt>`centos-art.sh'</tt>
671838
script execution environment.
671838

671838

Once global variables and function scripts have been loaded,

671838
<tt>`centos-art.sh'</tt> script executes the cli global function
671838
from <tt>`cli.sh'</tt> function script to retrive command-line arguments
671838
and define some default values that may be used later by specific
671838
function scripts (-- Removed(pxref:trunk Scripts Bash Functions) --).
671838

671838

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

671838
the following format:
671838

671838
centos-art arg1 --arg2=val2 --arg3=val3
671838
671838

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

671838
invoke <tt>`centos-art.sh'</tt> script. The <samp>`arg1'</samp> is required and
671838
represents the functionality you want to perform (e.g.,
671838
<samp>`verify'</samp>, <samp>`render'</samp>, <samp>`locale'</samp>, <samp>`manual'</samp>,
671838
etc.). The remaining arguments are modifiers to <samp>`arg1'</samp>. The
671838
<samp>`--arg2'</samp> definition is required and represets, specifically,
671838
the action inside the functionality you want to perform.  The
671838
<samp>`--arg3'</samp> and on, are optional.
671838

671838

Once command-line arguments have been retrived, the

671838
<tt>`centos-art.sh'</tt> script loads specific functionalities using the
671838
<tt>`cli_getFunctions.sh'</tt> function script. Only one specific
671838
functionality can be loaded at one script execution I.e., you run
671838
centos-art.sh script to run just one functionality.

671838

Functionalities are implemented by means of actions. Once the

671838
functionality has been initiazalized, actions initialization take
671838
place for that functionality. Actions initialization model is very
671838
similar to functions initialization model. But with the difference,
671838
that actions are loaded inside function environment, and so, share
671838
variables and functions defined inside function environment.
