3.46.1 Goals

63f275
831389

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

831389
script <samp>`verify'</samp> functionality.  The <samp>`verify'</samp>
831389
functionality of <tt>`centos-art.sh'</tt> script helps you to verify the
831389
workstation configuration you are planning to use as host for your
831389
working copy of CentOS Artwork Repository.

3.46.2 Description

081970
831389

The first time you download CentOS Artwork Repository you need to

831389
configure your workstation in order to use <tt>`centos-art.sh'</tt>
831389
script.  These preliminar configurations are based mainly on auxiliar
831389
RPM packages installation, symbolic links creations, and environment
831389
variables definitions.  The <samp>`verify'</samp> functionality of
831389
<tt>`centos-art.sh'</tt> script guides you through this preliminar
831389
configuration process.  
831389

831389

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

831389
appropriate way to use its <samp>`verify'</samp> functionality is not using
831389
the <tt>`centos-art.sh'</tt> script directly, but the absolute path to
831389
centos-art.sh script instead (i.e.,
831389
<tt>`~/artwork/trunk/Scripts/Bash/centos-art.sh'</tt>).  This is necessary
831389
because <tt>`centos-art'</tt> symbolic link, under <tt>`~/bin/'</tt>
831389
directory, has not been created yet.

3.46.2.1 Packages

63f275
831389

Installation of auxiliar RPM packages provides the software required

831389
to manipulate files inside the repository (e.g., image files,
831389
documentation files, translation files, script files, etc.). Most of
831389
RPM packages centos-art.sh script uses are shipped with
831389
CentOS distribution, and can be installed from CentOS base repository.
831389
The only exception is <samp>`inkscape'</samp>, the package we use to
831389
manipulate SVG files.  The <samp>`inkscape'</samp> package is not inside
831389
CentOS distribution so it needs to be installed from third party
831389
repositories.
831389

831389
info

Note

Configuration of third party repositories inside CentOS

831389
distribution is described in CentOS wiki, specifically in the
831389
following URL:
831389
http://wiki.centos.org/AdditionalResources/Repositories
831389

831389
831389

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

831389
sudo to request root privileges to execute yum's
831389
installation functionality.  If your user isn't defined as a
831389
privileged user--at least to run yum commands-- inside
831389
<tt>`/etc/sudoers'</tt> configuration file, you will not be able to
831389
perform package installation tasks as set in <tt>`centos-art.sh'</tt>
831389
script <samp>`verify'</samp> functionality. 
831389

831389

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

831389
do by yourself. If you don't have experience with sudo
831389
command, please read its man page running the command: man
831389
sudo. This reading will be very useful, and with some practice, you
831389
will be able to configure your users to have sudo
831389
privileges.

3.46.2.2 Links

831389
831389

Creation of symbolic links helps us to alternate between different

831389
implementations of <tt>`centos-art.sh'</tt> script-line (e.g.,
831389
<tt>`centos-art.sh'</tt>, for Bash implementation; <tt>`centos-art.py'</tt>,
831389
for Python implementation; <tt>`centos-art.pl'</tt>, for Perl
831389
implementation; and so on for other implementations). The
831389
<tt>`centos-art.sh'</tt> script-line definition takes place inside your
831389
personal binary (<tt>`~/bin/'</tt>) directory in order to make the script
831389
implementation --the one that <tt>`centos-art'</tt> links to-- available
831389
to PATH environment variable.
831389

831389

Creation of symbolic links helps us to reuse components from repository

831389
working copy. For example, color information files maintained inside
831389
your working copy must never be duplicated inside program-specific
831389
configuration directories that uses them in your workstation (e.g.,
831389
Gimp, Inkscape, etc.).  Instead, a symbolic link must be created for
831389
each one of them, from program-specific configuration directories to
831389
files in the working copy.  In this configuration, when someone
831389
commits changes to color information files up to central repository,
831389
they--the changes committed-- will be immediatly available to your
831389
programs the next time you update your working copy --the place
831389
inside your workstation those color information files are stored--.
831389

831389

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

831389
script functionalities available outside <tt>`trunk/'</tt> repository
831389
directory structure, but at its same level in repository tree. This is
831389
useful if you need to use the "render" functionality of
831389
centos-art.sh under <tt>`branches/'</tt> repository directory
831389
structure as you usually do inside <tt>`trunk/'</tt> repository directory
831389
structure. As consequence of this configuration, automation scripts
831389
cannot be branched under <tt>`branches/Scripts'</tt> directory structure.
831389

831389
831389
831389

3.46.2.3 Environment variables

831389
831389

Definition of environemnt variables helps us to set default values to

831389
our user session life. The user session environment variable defintion
831389
takes place in the user's <tt>`~/.bash_profile'</tt> file.  The
831389
<samp>`verify'</samp> functionality of <tt>`centos-art.sh'</tt> script doesn't
831389
modify your <tt>`~/.bash_profile'</tt> file.  
831389

831389

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

831389
evaluates the following environment variables:
831389

831389
831389
EDITOR
831389

Default text editor.

831389

831389

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

831389
pre-commit subversion messages, translation files, configuration
831389
files, script files, and similar text-based files.
831389

831389

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

831389
script uses <tt>`/usr/bin/vim'</tt> as default text editor. Otherwise, the
831389
following values are recognized by <tt>`centos-art.sh'</tt> script:
831389

831389
    831389
  • <tt>`/usr/bin/vim'</tt>
  • 831389
  • <tt>`/usr/bin/emacs'</tt>
  • 831389
  • <tt>`/usr/bin/nano'</tt>
  • 831389
    831389
    831389

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

    831389
    <tt>`centos-art.sh'</tt> uses <tt>`/usr/bin/vim'</tt> text editor by default. 
    831389

    831389
    831389
    TZ
    831389
    831389

    Default time zone representation.

    831389

    831389

    Time representation inside repository server is set to Coordinated

    831389
    Universal Time (UTC).  Time represetation inside repository working
    831389
    copies is set as their administrators personally define.  
    831389

    831389

    When repository working copies time representation be defined, it

    831389
    would be a very good convention to follow if working copies
    831389
    administrators would set their systems clock to use UTC.  Otherwise it
    831389
    would be difficult for working copies users to find out when changes
    831389
    were committed up to repository server exactly in time.
    831389

    831389
    Info

    Tip

    Coordinated Univeral Time (UTC) representation can be

    831389
    configured when you install CentOS distribution; or later, runing the
    831389
    system-config-date command at a shell prompt from your
    831389
    graphical interface.
    831389

    831389
    831389
    info

    Note

    If you set your system clock to use UTC representation,

    831389
    you also need to set the TZ environment variable inside
    831389
    <tt>`~/.bash_profile'</tt> as follows:
    831389

    export TZ=UTC
    831389

    This is required in order for your terminal to display the correct

    831389
    time information of your zone, taking UTC representation as reference.
    831389

    831389
    831389
    831389
    TEXTDOMAIN
    831389
    831389

    Default domain used to retrieve translated messages. This value is

    831389
    set in <tt>`initFunctions.sh'</tt> and shouldn't be changed.
    831389

    831389
    831389
    TEXTDOMAINDIR
    831389
    831389

    Default directory used to retrieve translated messages. This value is

    831389
    set in <tt>`initFunctions.sh'</tt> and shouldn't be changed.
    831389

    831389
    831389
    LANG
    831389
    831389

    Default locale information. This value is set when you start your

    831389
    session and can be changed using the <samp>`locale'</samp> functionality of
    831389
    <tt>`centos-art.sh'</tt> script (see section trunk/Scripts/Bash/Functions/Locale, for more information).
    831389

    831389

    3.46.3 Usage

    831389
    831389
    831389
    <samp>`centos-art verify --packages'</samp>
    831389

    Verify required packages your workstation needs in order to run the

    831389
    <tt>`centos-art.sh'</tt> script correctly.  If there are missing packages,
    831389
    the <tt>`centos-art.sh'</tt> script asks you to confirm their
    831389
    installation. When installing packages, the <tt>`centos-art.sh'</tt>
    831389
    script uses the yum application in order to achieve the
    831389
    task.
    831389

    831389

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

    831389
    already installed in your workstation, the message <samp>`The required
    831389
    packages are already installed.'</samp> is output for you to know. 
    831389

    831389
    831389
    <samp>`centos-art verify --links'</samp>
    831389

    Verify required links your workstation needs in order to run the

    831389
    centos-art command correctly.  If any required link is missing, the
    831389
    centos-art.sh script asks you to confirm their installation.
    831389
    To install required links, the centos-art.sh script uses the
    831389
    ln command.
    831389

    831389

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

    831389
    created in your workstation, the message <samp>`The required links are
    831389
    already installed.'</samp> is output for you to know. 
    831389

    831389

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

    831389
    the <tt>`centos-art.sh'</tt> script outputs the <samp>`Already exists as
    831389
    regular file.'</samp> message when listing required links that will be
    831389
    installed. Of course, as there is already a regular file where must be
    831389
    a link, no link is created. In such cases the <tt>`centos-art.sh'</tt>
    831389
    script will fall into a continue installation request for that missing
    831389
    link.  To end this continue request you can answer <samp>`No'</samp>, or
    831389
    remove the existent regular file to let <tt>`centos-art.sh'</tt> script
    831389
    install the link on its place.
    831389

    831389
    831389
    <samp>`centos-art verify --environment'</samp>
    831389
    <samp>`centos-art verify --environment --filter='regex''</samp>
    831389

    Output a brief description of environment variables used by

    831389
    <tt>`centos-art.sh'</tt> script. 
    831389

    831389

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

    831389
    the <samp>`regex'</samp> regular expression value. If <samp>`--filter'</samp> option
    831389
    is specified but <samp>`regex'</samp> value is not, the <tt>`centos-art.sh'</tt>
    831389
    script outputs information as if <samp>`--filter'</samp> option had not been
    831389
    provided at all.
