    2.70.1 Goals

    728c6d
    728c6d

    This section exists to organize files related to shell

    728c6d
    functionality of <tt>`centos-art.sh'</tt> script.
    728c6d

    728c6d
    728c6d
    728c6d

    2.70.2 Description

    728c6d
    728c6d

    The shell functionality of <tt>`centos-art.sh'</tt> script helps

    728c6d
    you to maintain bash scripts inside repository. For example, suppose
    728c6d
    you've created many functionalities for <tt>`centos-art.sh'</tt> script,
    728c6d
    and you want to use a common copyright and license note for
    728c6d
    consistency in all your script files. If you have a bunch of files,
    728c6d
    doing this one by one wouldn't be a big deal. In contrast, if the
    728c6d
    amount of files grows, updating the copyright and license note for all
    728c6d
    of them would be a task rather tedious. The shell functionality
    728c6d
    exists to solve maintainance tasks just as the one previously
    728c6d
    mentioned.
    728c6d

    728c6d

    When you use shell functionality to update copyright inside

    728c6d
    script files, it is required that your script files contain (at least)
    728c6d
    the following top commentary structure:
    728c6d

    728c6d
    728c6d
     1| #!/bin/bash
    728c6d
     2| #
    728c6d
     3| # doSomething.sh -- The function description goes here.
    728c6d
     4| # 
    728c6d
     5| # Copyright
    728c6d
     6| #
    728c6d
     7| # ...
    728c6d
     8| #
    728c6d
     9| # ----------------------------------------------------------------------
    728c6d
    10| # $Id$
    728c6d
    11| # ----------------------------------------------------------------------
    728c6d
    12|
    728c6d
    13| function doSomething {
    728c6d
    14|     
    728c6d
    15| }
    728c6d
    728c6d

    Figure 2.4: The functions script base comment structure

    728c6d
    728c6d

    728c6d

    Relevant lines in the above structure are lines from 5 to 9.

    728c6d
    Everything else in the file is left immutable.
    728c6d

    728c6d

    When you are updating copyright through shell

    728c6d
    functionality,  the <tt>`centos-art.sh'</tt> script replaces everything
    728c6d
    in-between line 5 --the first one matching <samp>`^# Copyright .+$'</samp>
    728c6d
    string-- and line 9--the first long dash separator matching <samp>`^#
    728c6d
    -+$'</samp>-- with the content of copyright template instance.
    728c6d

    728c6d
    Caution

    Caution

    Be sure to add the long dash separator that matches

    728c6d
    <samp>`^# -+$'</samp> regular expression before the function
    728c6d
    definition. Otherwise, if the <samp>`Copyright'</samp> line is present but no
    728c6d
    long dash separator exists, <tt>`centos-art.sh'</tt> will remove anything
    728c6d
    in-between the <samp>`Copyright'</samp> line and the end of file. This way you
    728c6d
    may lost your function definitions entirely.
    728c6d

    728c6d
    728c6d

    The copyright template instance is created from one copyright template

    728c6d
    stored in the <tt>`Config/tpl_forCopyright.sed'</tt> file.  The template
    728c6d
    instance is created once, and later removed when no longer needed. At
    728c6d
    this moment, when template instance is created, the
    728c6d
    <tt>`centos-art.sh'</tt> script takes advantage of automation in order to
    728c6d
    set copyright full name and date dynamically.
    728c6d

    728c6d

    When you use shell functionality to update copyright, the first

    728c6d
    thing <tt>`shell'</tt> functionality does is requesting copyright
    728c6d
    information to user, and later, if values were left empty (i.e., no
    728c6d
    value was typed before pressing RET key), the <tt>`shell'</tt>
    728c6d
    functionality uses its own default values.
    728c6d

    728c6d

    When shell functionality uses its own default values, the final

    728c6d
    copyright note looks like the following:
    728c6d

    728c6d
    728c6d
     1| #!/bin/bash
    728c6d
     2| #
    728c6d
     3| # doSomthing.sh -- The function description goes here.

    Figure 2.5: The function script comment example

    728c6d
    728c6d

    728c6d

    Relevant lines in the above structure are lines from 5 to 22. Pay

    728c6d
    attention how the copyright line was built, and how the license was
    728c6d
    added into the top comment where previously was just three dots.
    728c6d
    Everything else in the file was left immutable. 
    728c6d

    728c6d

    To change copyright information (i.e., full name or year information),

    728c6d
    run the shell functionality over the root directory containing
    728c6d
    the script files you want to update copyright in and enter the
    728c6d
    appropriate information when it be requested. You can run the
    728c6d
    shell functionality as many times as you need to.
    728c6d

    728c6d

    To change copyright license (i.e., the text in-between lines 7 and

    728c6d
    20), you need to edit the <tt>`Config/tpl_forCopyright.sed'</tt> file, set
    728c6d
    the appropriate information, and run the shell functionality
    728c6d
    once again for changes to take effect over the files you specify.

    2.70.3 Usage

    728c6d
    728c6d
    728c6d
    centos-art sh --update-copyright='path/to/dir'
    728c6d
    centos-art sh --update-copyright='path/to/dir' --filter='regex'
    728c6d

    Use these commands to update copyright information in <samp>`.sh'</samp> files

    728c6d
    under <samp>`path/to/dir'</samp> directory. 
    728c6d

    728c6d
    728c6d
    728c6d

    When you provide <samp>`--filter='regex''</samp> argument, the list of files

    728c6d
    to process is reduced as specified in <samp>`regex'</samp> regular expression.
    728c6d
    Inside <tt>`centos-art.sh'</tt> script, the <samp>`regex'</samp> regular
    728c6d
    expression is used in combination with find command to look
    728c6d
    for files matching the regular expression path pattern.
    728c6d

    728c6d
    Warning

    Warning

    In order for <samp>`regex'</samp> regular expression to match

    728c6d
    a file, the <samp>`regex'</samp> regular expresion must match the whole file
    728c6d
    path not just the file name. 
    728c6d

    728c6d
    728c6d

    For example, if you want to match all <tt>`render.conf.sh'</tt> files

    728c6d
    inside <tt>`path/to/dir'</tt>, use the .+/render.conf regular
    728c6d
    expression.  Later, <tt>`centos-art.sh'</tt> script uses this value inside
    728c6d
    ^$REGEX\.sh$ expression in order to build the final regular
    728c6d
    expression (i.e., ^.+/render.conf\.sh$) that is evaluated
    728c6d
    against available file paths inside the list of files to process.
    728c6d

    728c6d

    Exceptionally, when you provide <samp>`--filter='regex''</samp> in the way

    728c6d
    that <samp>`regex'</samp>, appended to <samp>`path/to/dir/'</samp> (i.e.
    728c6d
    <samp>`path/to/dir/regex'</samp>), matches a regular file; the
    728c6d
    <tt>`centos-art.sh'</tt> script uses the file matching as only file in the
    728c6d
    list of files to process.
