3.44.1 Goals

54b5a5
749e81

This section exists to organize files related to shell

749e81
functionality of <tt>`centos-art.sh'</tt> script.

3.44.2 Description

54b5a5
749e81

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

749e81
you to maintain bash scripts inside repository. For example, suppose
749e81
you've created many functionalities for <tt>`centos-art.sh'</tt> script,
749e81
and you want to use a common copyright and license note for
749e81
consistency in all your script files. If you have a bunch of files,
749e81
doing this one by one wouldn't be a big deal. In contrast, if the
749e81
amount of files grows, updating the copyright and license note for all
749e81
of them would be a task rather tedious. The shell functionality
749e81
exists to solve maintainance tasks just as the one previously
749e81
mentioned.

749e81

When you use shell functionality to update copyright inside

749e81
script files, it is required that your script files contain (at least)
749e81
the following top commentary structure:
63f275

749e81
 1| #!/bin/bash
749e81
 2| #
749e81
 3| # doSomething.sh -- The function description goes here.
749e81
 4| # 
749e81
 5| # Copyright
749e81
 6| #
749e81
 7| # ...
749e81
 8| #
749e81
 9| # ----------------------------------------------------------------------
749e81
10| # $Id$
749e81
11| # ----------------------------------------------------------------------
749e81
12|
749e81
13| function doSomething {
749e81
14|     
749e81
15| }
035049
749e81

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

749e81
Everything else in the file is left immutable.

749e81

When you are updating copyright through shell

749e81
functionality,  the <tt>`centos-art.sh'</tt> script replaces everything
749e81
in-between line 5 --the first one matching <samp>`^# Copyright .+$'</samp>
749e81
string-- and line 9--the first long dash separator matching <samp>`^#
749e81
-+$'</samp>-- with the content of copyright template instance.
49b888

749e81
Caution

Caution

Be sure to add the long dash separator that matches

749e81
<samp>`^# -+$'</samp> regular expression before the function
749e81
definition. Otherwise, if the <samp>`Copyright'</samp> line is present but no
749e81
long dash separator exists, <tt>`centos-art.sh'</tt> will remove anything
749e81
in-between the <samp>`Copyright'</samp> line and the end of file. This way you
749e81
may lost your function definitions entirely.
749e81

0d952c
749e81

The copyright template instance is created from one copyright template

749e81
stored in the <tt>`Config/tpl_forCopyright.sed'</tt> file.  The template
749e81
instance is created once, and later removed when no longer needed. At
749e81
this moment, when template instance is created, the
749e81
<tt>`centos-art.sh'</tt> script takes advantage of automation in order to
749e81
set copyright full name and date dynamically.
0d952c

749e81

When you use shell functionality to update copyright, the first

749e81
thing <tt>`shell'</tt> functionality does is requesting copyright
749e81
information to user, and later, if values were left empty (i.e., no
749e81
value was typed before pressing RET key), the <tt>`shell'</tt>
749e81
functionality uses its own default values.
e68a7a

749e81

When shell functionality uses its own default values, the final

749e81
copyright note looks like the following:

035049
749e81

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

749e81
attention how the copyright line was built, and how the license was
749e81
added into the top comment where previously was just three dots.
749e81
Everything else in the file was left immutable. 
60c152

749e81

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

749e81
run the shell functionality over the root directory containing
749e81
the script files you want to update copyright in and enter the
749e81
appropriate information when it be requested. You can run the
749e81
shell functionality as many times as you need to.
3d6160

749e81

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

749e81
20), you need to edit the <tt>`Config/tpl_forCopyright.sed'</tt> file, set
749e81
the appropriate information, and run the shell functionality
749e81
once again for changes to take effect over the files you specify.

3.44.3 Usage

008ee0
63f275
749e81
centos-art sh --update-copyright='path/to/dir'
749e81
centos-art sh --update-copyright='path/to/dir' --filter='regex'
749e81

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

749e81
under <samp>`path/to/dir'</samp> directory. 
749e81

0d952c
0d952c
749e81

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

749e81
to process is reduced as specified in <samp>`regex'</samp> regular expression.
749e81
Inside <tt>`centos-art.sh'</tt> script, the <samp>`regex'</samp> regular
749e81
expression is used in combination with find command to look
749e81
for files matching the regular expression path pattern.
749e81

749e81
Warning

Warning

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

749e81
a file, the <samp>`regex'</samp> regular expresion must match the whole file
749e81
path not just the file name. 
749e81

749e81
749e81

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

749e81
inside <tt>`path/to/dir'</tt>, use the .+/render.conf regular
749e81
expression.  Later, <tt>`centos-art.sh'</tt> script uses this value inside
749e81
^$REGEX\.sh$ expression in order to build the final regular
749e81
expression (i.e., ^.+/render.conf\.sh$) that is evaluated
749e81
against available file paths inside the list of files to process.
749e81

749e81

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

749e81
that <samp>`regex'</samp>, appended to <samp>`path/to/dir/'</samp> (i.e.
749e81
<samp>`path/to/dir/regex'</samp>), matches a regular file; the
749e81
<tt>`centos-art.sh'</tt> script uses the file matching as only file in the
749e81
list of files to process.
