@subsection Goals

The @file{trunk/Scripts/Bash} directory exists to organize the

``trunk'' development line of @command{centos-art.sh} automation

script.  The @command{centos-art.sh} script standardize frequent tasks

inside your working copy of CentOS Artwork Repository.

@subsection Description

The best way to understand @command{centos-art.sh} automation script

is studying its source code. The @command{centos-art.sh} script is

splited in several configuration and function files which are loaded

when the @command{centos-art.sh} script is executed. This section

describes the order in which @command{centos-art.sh} loads its

configuration and function files.

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

operating system trys to execute that command. In order to execute the

command, the operating system needs to know where it is, so the

operating system uses the @var{PATH} environment variable to look for

that command's location. If your system was prepared to use CentOS

Artwork Repository correctly (see usage section above), you should

have a symbolic link inside @file{~/bin/} directory that points to the

@command{centos-art.sh} script file. As @file{~/bin/} directory is, by

default, inside @var{PATH} environment variable, the execution of

@command{centos-art} command runs the @file{centos-art.sh} script.

When @command{centos-art.sh} script is executed, the first it does is

execute the @file{trunk/Scripts/Bash/initFunctions.sh} file to

initialize @command{gettext} variables and all function scripts inside

@file{trunk/Scripts/Bash/Functions} directory. 

Once @command{gettext} variables and all function scripts have been

initialized, the @command{centos-art.sh} script initializes its

environment variables using the @command{cli_getVariables} function.

At this point the @command{centos-art.sh} script calls the

@command{cli_getActions} function from @command{cli_getVariables}

function's bottom. 

The @command{cli_getActions} function defines which actions the

@command{centos-art.sh} script is able to perform. Inside

@command{cli_getActions} function, actions are defined combining

positional arguments and function calls.

@subsubsection The identity matching list

The identity matching list is used by identity rendering functions to

define the relation between translation files and identity design

templates. 

@subsubsection Adding new features

To add new features inside @command{centos-art.sh} script, you need to

set positional arguments and function calls inside

@command{cli_getActions} function for the new function or functions

required by the new feature you want to add.

@subsection Usage

@subsubsection The @command{centos-art} @samp{check} action

This feature is supported through the following command:

@table @samp

@item centos-art check

This command verifies paths, symbolic links, installed packages and

everything your workstation needs in order to run the

@command{centos-art} command correctly. 

@quotation

@strong{Warning} If this is the first time you run

@command{centos-art} command, the appropriate way to execute check

action is not using the @command{centos-art} command, but the absolute

path to @command{centos-art.sh} script instead:

@verbatim

~/artwork/trunk/Scripts/Bash/centos-art.sh check

@end verbatim

@end quotation

@end table

@subsubsection The @command{centos-art} @samp{search} action

This feature is not supported yet.

@table @samp

@item centos-art search 'pattern' 

Use this command to find directories and files that match exactly the

posix-regular expression set in @samp{pattern} as in @samp{^pattern$}.

@item centos-art search 'pattern1 pattern2 patternN' 

Use this command to search repository entries that match pattern1

@emph{or} patter2 @emph{or} patternN as in

@samp{'^.*(pattern1|pattern2|patternN).*$'}.

@item centos-art search 'path/to/dir1 path/to/dir2 path/to/dirN' 

Use this command to search repository entries that match

@samp{path/to/dir1} @emph{or} @samp{path/to/dir2}, @emph{or}

@samp{path/to/dirN} as in

@samp{^.*(path/to/dir1|path/to/dir2|path/to/dirN).*$'}.

@end table

@subsubsection The @command{centos-art} @samp{locale-art} action

This feature is not supported yet.

@table @samp

@item centos-art locale-art 'path/to/dir' --edit

@item centos-art locale-art 'path/to/dir' --edit='filename'

@item centos-art locale-art 'path/to/dir' --list

@item centos-art locale-art 'path/to/dir' --list='filename'

@end table

@subsubsection The @command{centos-art} @samp{license} action

This feature is supported through the following command:

@table @samp

@item centos-art license

Use this command to see a brief description of @command{centos-art}

command its copyright and its license notes.
