Name
----
centos-art.sh - The CentOS artwork repository automation tool
Synopsis
--------
*centos-art.sh* [*--help*|*--version*]::
This command provides information about the script itself.
*centos-art.sh* *MODULE* [*--help|--version*]::
This command provides information about the specified module. See
the xref:Modules[] section below to see which modules are
available.
*centos-art.sh* *MODULE* [*OPTIONS*]::
This command executes the specified module. Options here are
module-specific. See the xref:Modules[] section below to see which
modules are available.
Description
-----------
*centos-art.sh* exists to standardize frequent tasks inside the CentOS
repository.
When you execute the *centos-art.sh* script in a terminal, it will
request the absolute path where you stored your working copy of CentOS
artwork repository. To avoid the absolute path request every time you
execute the script, you can edit the +~/.bash_profile+ file and
declare the absolute path to your working copy there, as value to
TCAR_BASEDIR variable.
Once *centos-art.sh* script knows what the absolute path to your
working copy is, it executes the file *centos-art.conf* to load
default values to configuration variables into its execution
environment. After configuration variables have been loaded in the
execution environment, the script looks for supported options in the
first argument. If the options passed are recognized the script
process them. If the options aren't recognized or no option is passed
at all, the *centos-art.sh* script exports common functions and
executes the module specified as first argument, assuming the first
argument is a valid module name of course. Finally, the
*centos-art.sh* script waits for the module script to conclude its job
and exits the as described in the xref:exit[] section.

* 1 -- Exit with errors.

Modules
-------
From version 0.5 on, *centos-art.sh* script introduces the idea of
modules to its base design. Modules are individual execution
environments that may nest themselves one inside another to achieve
high levels maintainability. Modules make it possible to divide a big
task into smaller tasks that can be easier to debug, maintain and
share with other modules.
The following modules are available for *centos-art.sh* script:
*prepare*::
This module standardizes configuration tasks needed by your
working copy (e.g., verify whether required packages are installed
or not in your workstation). This is the first task you should run
in your workstation, just after downloading a fresh working copy
of CentOS artwork repository.
*render*::
This module standardizes the way content is produced inside the
repository. This function relies on configuration files to do its
work. Whenever you need to produce images, documentation or
localized content this is the module you'll need to use.
*locale*::
This module standardizes the way translatable strings are
retrieved from source files and put into portable objects for you
to edit. Portable objects produced by this module are used by
*render* module to produce localized content. Whenever you need
to produce the intermediate files holding the translatable strings
required to produce localized content, use this module.
*help*::
This module standardizes the way documentation is produced inside
the repository. Whenever you need to manage documentation source
files inside the repository, use this module.
*tuneup*::
This module standardizes maintenance tasks frequently run inside
the repository.
*vcs*::
This module standardizes the way version control tasks are
performed inside the repository. This module is used internally
and you probably don't need to use it from the command line. This
module is the interface that let us support different version
control systems inside *centos-art.sh* script.
*pack*::
This module standardizes the way RPM packages are produced from
content available in the repository. When ever you need to produce
RPM packages with information available in the repository, use
this module.
Directory Structure
~~~~~~~~~~~~~~~~~~~
Inside the repository, modules related to *centos-art.sh* script are
stored in the directory +Automation/Modules+.
*Modules/*::
This directory contains module's modules.
*Manuals/*::
This directory contains module's documentation produced by *help*
module. The structure of this directory looks as follow:
+
----------------------------------------------------------------------
Manuals/
|-- ${LANG}/
| |-- man${SECTION_NUMBER}
| `-- ${MODULE_NAME}.${SECTION_NUMBER}
`-- man${SECTION_NUMBER}
`-- ${MODULE_NAME}.${SECTION_NUMBER}
----------------------------------------------------------------------
*Locales/*::
This directory contains module's translations produced by *locale*
module. The structure of this directory looks as follow:
+
----------------------------------------------------------------------
Locales/
`-- ${LANG}/
|-- LC_MESSAGES
| |-- ${MODULE_NAME}.sh.mo
| `-- ${MODULE_NAME}.docbook.mo
|-- ${MODULE_NAME}.sh.po
|-- ${MODULE_NAME}.sh.pot
|-- ${MODULE_NAME}.docbook.po
`-- ${MODULE_NAME}.docbook.pot
----------------------------------------------------------------------
*Scripts/*::
This directory contains function scripts written by module's
writers. Here is where all the tasks the module is useful for are
written and stored in. As convention the following structure is
used:
+
----------------------------------------------------------------------
Scripts/
`-- ${MODULE_NAME}_${FUNCTION_NAME}.sh
----------------------------------------------------------------------
+
{asccidoc-br}
+
Inside each function script, there is a top comment where you should
put the name of the function script, a brief description about what it
does, as well as author and copying information. After the top comment
and separated by one white line, you should define the function
sentence using the long format.

[NOTE]
If your are planning to contribute a new module to *centos-art.sh*
script, please, consider using the layout described above for all your
function scripts, consistently.
*$\{MODULE_NAME}.asciidoc*::
This file contains the module's documentation source. From this
file it is possible to produce the same documentation in other
formats including manpage, html and pdf. Whenever you need to
improve the module's documentation, edit this file.
*$\{MODULE_NAME}.conf*::
This file contains the module's configuration variables. These
variables are exported to the environment and remain there as long
as the script execution environment is alive. Some variables are
read-only others not.
+
The configuration file provides explanation about each environment
variable it exports. If you want to know more about what these
variables are, open this file and read the comments near each
variable.
*$\{MODULE_NAME}.sh*::
This is the module's initialization script. The first file
executed when the module called from the command-line. This file
provides access to argument parsing and controls how
module-specific function scripts are called. This is the starting
point for writing modules. You can write a complete module using
this file only but, frequently, it is convenient as the module
complexity grows to divide it in smaller pieces (function scripts)
to improve maintainability and error findings.
Options
-------
*--help*::
