2.73.1 Goals

06d106
52772c

This section exists to organize files related to shell

52772c
functionality of <tt>`centos-art.sh'</tt> script.
52772c

06d106
52772c

2.73.2 Description

06d106
52772c

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

52772c
you to maintain bash scripts inside repository. For example, suppose
52772c
you've created many functionalities for <tt>`centos-art.sh'</tt> script,
52772c
and you want to use a common copyright and license note for
52772c
consistency in all your script files. If you have a bunch of files,
52772c
doing this one by one wouldn't be a big deal. In contrast, if the
52772c
amount of files grows, updating the copyright and license note for all
52772c
of them would be a task rather tedious. The shell functionality
52772c
exists to solve maintainance tasks just as the one previously
52772c
mentioned.
52772c

52772c

When you use shell functionality to update copyright inside

52772c
script files, it is required that your script files contain (at least)
52772c
the following top commentary structure:
52772c

52772c
52772c
 1| #!/bin/bash
52772c
 2| #
52772c
 3| # doSomething.sh -- The function description goes here.
52772c
 4| # 
52772c
 5| # Copyright
52772c
 6| #
52772c
 7| # ...
52772c
 8| #
52772c
 9| # ----------------------------------------------------------------------
52772c
10| # $Id$
52772c
11| # ----------------------------------------------------------------------
52772c
12|
52772c
13| function doSomething {
52772c
14|     
52772c
15| }
52772c
52772c

Figure 2.4: The functions script base comment structure

52772c
52772c

52772c

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

52772c
Everything else in the file is left immutable.
52772c

52772c

When you are updating copyright through shell

52772c
functionality,  the <tt>`centos-art.sh'</tt> script replaces everything
52772c
in-between line 5 --the first one matching <samp>`^# Copyright .+$'</samp>
52772c
string-- and line 9--the first long dash separator matching <samp>`^#
52772c
-+$'</samp>-- with the content of copyright template instance.
52772c

52772c
Caution

Caution

Be sure to add the long dash separator that matches

52772c
<samp>`^# -+$'</samp> regular expression before the function
52772c
definition. Otherwise, if the <samp>`Copyright'</samp> line is present but no
52772c
long dash separator exists, <tt>`centos-art.sh'</tt> will remove anything
52772c
in-between the <samp>`Copyright'</samp> line and the end of file. This way you
52772c
may lost your function definitions entirely.
52772c

06d106
52772c

The copyright template instance is created from one copyright template

52772c
stored in the <tt>`Config/tpl_forCopyright.sed'</tt> file.  The template
52772c
instance is created once, and later removed when no longer needed. At
52772c
this moment, when template instance is created, the
52772c
<tt>`centos-art.sh'</tt> script takes advantage of automation in order to
52772c
set copyright full name and date dynamically.
52772c

52772c

When you use shell functionality to update copyright, the first

52772c
thing <tt>`shell'</tt> functionality does is requesting copyright
52772c
information to user, and later, if values were left empty (i.e., no
52772c
value was typed before pressing RET key), the <tt>`shell'</tt>
52772c
functionality uses its own default values.
52772c

52772c

When shell functionality uses its own default values, the final

52772c
copyright note looks like the following:
52772c

52772c
52772c
 1| #!/bin/bash
52772c
 2| #
52772c
 3| # doSomthing.sh -- The function description goes here.

Figure 2.5: The function script comment example

52772c
52772c

52772c

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

52772c
attention how the copyright line was built, and how the license was
52772c
added into the top comment where previously was just three dots.
52772c
Everything else in the file was left immutable. 
52772c

52772c

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

52772c
run the shell functionality over the root directory containing
52772c
the script files you want to update copyright in and enter the
52772c
appropriate information when it be requested. You can run the
52772c
shell functionality as many times as you need to.
52772c

52772c

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

52772c
20), you need to edit the <tt>`Config/tpl_forCopyright.sed'</tt> file, set
52772c
the appropriate information, and run the shell functionality
52772c
once again for changes to take effect over the files you specify.

2.73.3 Usage

06d106
52772c
52772c
centos-art sh --update-copyright='path/to/dir'
52772c
centos-art sh --update-copyright='path/to/dir' --filter='regex'
52772c

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

52772c
under <samp>`path/to/dir'</samp> directory. 
52772c

52772c
06d106
52772c

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

52772c
to process is reduced as specified in <samp>`regex'</samp> regular expression.
52772c
Inside <tt>`centos-art.sh'</tt> script, the <samp>`regex'</samp> regular
52772c
expression is used in combination with find command to look
52772c
for files matching the regular expression path pattern.
52772c

52772c
Warning

Warning

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

52772c
a file, the <samp>`regex'</samp> regular expresion must match the whole file
52772c
path not just the file name. 
52772c

06d106
52772c

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

52772c
inside <tt>`path/to/dir'</tt>, use the .+/render.conf regular
52772c
expression.  Later, <tt>`centos-art.sh'</tt> script uses this value inside
52772c
^$REGEX\.sh$ expression in order to build the final regular
52772c
expression (i.e., ^.+/render.conf\.sh$) that is evaluated
52772c
against available file paths inside the list of files to process.
52772c

52772c

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

52772c
that <samp>`regex'</samp>, appended to <samp>`path/to/dir/'</samp> (i.e.
52772c
<samp>`path/to/dir/regex'</samp>), matches a regular file; the
52772c
<tt>`centos-art.sh'</tt> script uses the file matching as only file in the
52772c
list of files to process.
