3.47.1 Goals

6414c4
6414c4

This section exists to organize files related to <tt>`centos-art.sh'</tt>

6414c4
script <samp>`verify'</samp> functionality.  The <samp>`verify'</samp>
6414c4
functionality of <tt>`centos-art.sh'</tt> script helps you to verify the
6414c4
workstation configuration you are planning to use as host for your
6414c4
working copy of CentOS Artwork Repository.
6414c4

6414c4

3.47.2 Description

6414c4
6414c4

The first time you download CentOS Artwork Repository you need to

6414c4
configure your workstation in order to use <tt>`centos-art.sh'</tt>
6414c4
script.  These preliminar configurations are based mainly on auxiliar
6414c4
RPM packages installation, symbolic links creations, and environment
6414c4
variables definitions.  The <samp>`verify'</samp> functionality of
6414c4
<tt>`centos-art.sh'</tt> script guides you through this preliminar
6414c4
configuration process.  
6414c4

6414c4

If this is the first time you run <tt>`centos-art.sh'</tt> script, the

6414c4
appropriate way to use its <samp>`verify'</samp> functionality is not using
6414c4
the <tt>`centos-art.sh'</tt> script directly, but the absolute path to
6414c4
centos-art.sh script instead (i.e.,
6414c4
<tt>`~/artwork/trunk/Scripts/Bash/centos-art.sh'</tt>).  This is necessary
6414c4
because <tt>`centos-art'</tt> symbolic link, under <tt>`~/bin/'</tt>
6414c4
directory, has not been created yet.

3.47.2.1 Packages

4c79b5
6414c4

Installation of auxiliar RPM packages provides the software required

6414c4
to manipulate files inside the repository (e.g., image files,
6414c4
documentation files, translation files, script files, etc.). Most of
6414c4
RPM packages centos-art.sh script uses are shipped with
6414c4
CentOS distribution, and can be installed from CentOS base repository.
6414c4
The only exception is <samp>`inkscape'</samp>, the package we use to
6414c4
manipulate SVG files.  The <samp>`inkscape'</samp> package is not inside
6414c4
CentOS distribution so it needs to be installed from third party
6414c4
repositories.
6414c4

6414c4
info

Note

Configuration of third party repositories inside CentOS

6414c4
distribution is described in CentOS wiki, specifically in the
6414c4
following URL:
6414c4
http://wiki.centos.org/AdditionalResources/Repositories
6414c4

6414c4
6414c4

Before installing packages, the <tt>`centos-art.sh'</tt> script uses

6414c4
sudo to request root privileges to execute yum's
6414c4
installation functionality.  If your user isn't defined as a
6414c4
privileged user--at least to run yum commands-- inside
6414c4
<tt>`/etc/sudoers'</tt> configuration file, you will not be able to
6414c4
perform package installation tasks as set in <tt>`centos-art.sh'</tt>
6414c4
script <samp>`verify'</samp> functionality. 
6414c4

6414c4

Setting sudo privileges to users is an administrative task you have to

6414c4
do by yourself. If you don't have experience with sudo
6414c4
command, please read its man page running the command: man
6414c4
sudo. This reading will be very useful, and with some practice, you
6414c4
will be able to configure your users to have sudo
6414c4
privileges.

3.47.2.2 Links

4c79b5
6414c4

Creation of symbolic links helps us to alternate between different

6414c4
implementations of <tt>`centos-art.sh'</tt> script-line (e.g.,
6414c4
<tt>`centos-art.sh'</tt>, for Bash implementation; <tt>`centos-art.py'</tt>,
6414c4
for Python implementation; <tt>`centos-art.pl'</tt>, for Perl
6414c4
implementation; and so on for other implementations). The
6414c4
<tt>`centos-art.sh'</tt> script-line definition takes place inside your
6414c4
personal binary (<tt>`~/bin/'</tt>) directory in order to make the script
6414c4
implementation --the one that <tt>`centos-art'</tt> links to-- available
6414c4
to PATH environment variable.
6414c4

6414c4

Creation of symbolic links helps us to reuse components from repository

6414c4
working copy. For example, color information files maintained inside
6414c4
your working copy must never be duplicated inside program-specific
6414c4
configuration directories that uses them in your workstation (e.g.,
6414c4
Gimp, Inkscape, etc.).  Instead, a symbolic link must be created for
6414c4
each one of them, from program-specific configuration directories to
6414c4
files in the working copy.  In this configuration, when someone
6414c4
commits changes to color information files up to central repository,
6414c4
they--the changes committed-- will be immediatly available to your
6414c4
programs the next time you update your working copy --the place
6414c4
inside your workstation those color information files are stored--.
6414c4

6414c4

Creation of symbolic links helps us to make <tt>`centos-art.sh'</tt>

6414c4
script functionalities available outside <tt>`trunk/'</tt> repository
6414c4
directory structure, but at its same level in repository tree. This is
6414c4
useful if you need to use the "render" functionality of
6414c4
centos-art.sh under <tt>`branches/'</tt> repository directory
6414c4
structure as you usually do inside <tt>`trunk/'</tt> repository directory
6414c4
structure. As consequence of this configuration, automation scripts
6414c4
cannot be branched under <tt>`branches/Scripts'</tt> directory structure.

3.47.2.3 Environment variables

0d952c
6414c4

Definition of environemnt variables helps us to set default values to

6414c4
our user session life. The user session environment variable defintion
6414c4
takes place in the user's <tt>`~/.bash_profile'</tt> file.  The
6414c4
<samp>`verify'</samp> functionality of <tt>`centos-art.sh'</tt> script doesn't
6414c4
modify your <tt>`~/.bash_profile'</tt> file.  
6414c4

6414c4

The <samp>`verify'</samp> functionality of <tt>`centos-art.sh'</tt> script

6414c4
evaluates the following environment variables:
6414c4

6414c4
6414c4
EDITOR
6414c4

Default text editor.

6414c4

6414c4

The <tt>`centos-art.sh'</tt> script uses default text EDITOR to edit

6414c4
pre-commit subversion messages, translation files, configuration
6414c4
files, script files, and similar text-based files.
0d952c

6414c4

If EDITOR environment variable is not set, <tt>`centos-art.sh'</tt>

6414c4
script uses <tt>`/usr/bin/vim'</tt> as default text editor. Otherwise, the
6414c4
following values are recognized by <tt>`centos-art.sh'</tt> script:
6414c4

6414c4
    6414c4
  • <tt>`/usr/bin/vim'</tt>
  • 6414c4
  • <tt>`/usr/bin/emacs'</tt>
  • 6414c4
  • <tt>`/usr/bin/nano'</tt>
  • 6414c4
    6414c4
    6414c4

    If no one of these values is set in EDITOR environment variable,

    6414c4
    <tt>`centos-art.sh'</tt> uses <tt>`/usr/bin/vim'</tt> text editor by default. 
    6414c4

    6414c4
    6414c4
    TEXTDOMAIN
    6414c4
    6414c4

    Default domain used to retrieve translated messages. This variable is

    6414c4
    set in <tt>`initFunctions.sh'</tt> and shouldn't be changed.
    6414c4

    6414c4
    6414c4
    TEXTDOMAINDIR
    6414c4
    6414c4

    Default directory used to retrieve translated messages. This variable

    6414c4
    is set in <tt>`initFunctions.sh'</tt> and shouldn't be changed.
    6414c4

    6414c4
    6414c4
    LANG
    6414c4
    6414c4

    Default locale information.

    6414c4

    6414c4

    This variable is initially set in the configuration process of CentOS

    6414c4
    distribution installer (i.e., Anaconda), specifically in the
    6414c4
    <samp>`Language'</samp> step; or once installed using the
    6414c4
    system-config-language tool.
    6414c4

    6414c4

    The <tt>`centos-art.sh'</tt> script uses the LANG environment

    6414c4
    variable to know in which language the script messages are printed
    6414c4
    out.
    6414c4

    6414c4
    6414c4
    TZ
    6414c4
    6414c4

    Default time zone representation.

    6414c4

    6414c4

    This variable is initially set in the configuration process of CentOS

    6414c4
    distribution installer (i.e., Anaconda), specifically in the
    6414c4
    <samp>`Date and time'</samp> step; or once installed using the
    6414c4
    system-config-date tool.
    6414c4

    6414c4

    The <tt>`centos-art.sh'</tt> script doesn't use the TZ environment

    6414c4
    variable information at all. Instead, this variable is used by the
    6414c4
    system shell to show the time information according to your phisical
    6414c4
    location on planet Earth.  
    6414c4

    6414c4

    Inside your computer, the time information is firstly set in the BIOS

    6414c4
    clock (which may need correction), and later in the configuration
    6414c4
    process of CentOS distribution installer (or later, by any of the
    6414c4
    related configuration tools inside CentOS distribution).  Generally,
    6414c4
    setting time information is a straight-forward task and configuration
    6414c4
    tools available do cover most relevant location. However, if you need
    6414c4
    a time precision not provided by the configuration tools available
    6414c4
    inside CentOS distribution then, using TZ variable may be
    6414c4
    necessary.
    6414c4

    6414c4
    Convenction

    Convenction

    In order to keep changes syncronized between

    6414c4
    central repository and its working copies: configure both repository
    6414c4
    server and workstations (i.e., the place where each working copy is
    6414c4
    set on) to use Coordinated Universal Time (UTC) as base time
    6414c4
    representation.  Later, correct the time information for your specific
    6414c4
    location using time zone correction.
    6414c4

    6414c4
    6414c4

    The format of TZ environment variable is described in

    6414c4
    <tt>`tzset(3)'</tt> manual page.

    3.47.3 Usage

    6aec21
    6414c4
    6414c4
    centos-art verify --packages
    6414c4
    6414c4

    Verify required packages your workstation needs in order to run the

    6414c4
    <tt>`centos-art.sh'</tt> script correctly.  If there are missing packages,
    6414c4
    the <tt>`centos-art.sh'</tt> script asks you to confirm their
    6414c4
    installation. When installing packages, the <tt>`centos-art.sh'</tt>
    6414c4
    script uses the yum application in order to achieve the
    6414c4
    task.
    6414c4

    6414c4

    In case all packages required by <tt>`centos-art.sh'</tt> script are

    6414c4
    already installed in your workstation, the message <samp>`The required
    6414c4
    packages are already installed.'</samp> is output for you to know. 
    6414c4

    6414c4
    6414c4
    centos-art verify --links
    6414c4
    6414c4

    Verify required links your workstation needs in order to run the

    6414c4
    centos-art command correctly.  If any required link is missing, the
    6414c4
    centos-art.sh script asks you to confirm their installation.
    6414c4
    To install required links, the centos-art.sh script uses the
    6414c4
    ln command.
    035049

    6414c4

    In case all links required by <tt>`centos-art.sh'</tt> script are already

    6414c4
    created in your workstation, the message <samp>`The required links are
    6414c4
    already installed.'</samp> is output for you to know. 
    6414c4

    6414c4

    In case a regular file exists with the same name of a required link,

    6414c4
    the <tt>`centos-art.sh'</tt> script outputs the <samp>`Already exists as
    6414c4
    regular file.'</samp> message when listing required links that will be
    6414c4
    installed. Of course, as there is already a regular file where must be
    6414c4
    a link, no link is created. In such cases the <tt>`centos-art.sh'</tt>
    6414c4
    script will fall into a continue installation request for that missing
    6414c4
    link.  To end this continue request you can answer <samp>`No'</samp>, or
    6414c4
    remove the existent regular file to let <tt>`centos-art.sh'</tt> script
    6414c4
    install the link on its place.
    6414c4

    6414c4
    6414c4
    centos-art verify --environment
    6414c4
    centos-art verify --environment --filter='regex'
    6414c4
    6414c4

    Output a brief description of environment variables used by

    6414c4
    <tt>`centos-art.sh'</tt> script. 
    6414c4

    6414c4

    If <samp>`--filter'</samp> option is provided, output is reduced as defined in

    6414c4
    the <samp>`regex'</samp> regular expression value. If <samp>`--filter'</samp> option
    6414c4
    is specified but <samp>`regex'</samp> value is not, the <tt>`centos-art.sh'</tt>
    6414c4
    script outputs information as if <samp>`--filter'</samp> option had not been
    6414c4
    provided at all.
