3.44.1 Goals

54b5a5
63f275

This section exists to organize files related to shell

63f275
functionality of <tt>`centos-art.sh'</tt> script.
63f275

3.44.2 Description

54b5a5
63f275

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

63f275
you to maintain bash scripts inside repository. For example, suppose
63f275
you've created many functionalities for <tt>`centos-art.sh'</tt> script,
63f275
and you want to use a common copyright and license note for
63f275
consistency in all your script files. If you have a bunch of files,
63f275
doing this one by one wouldn't be a big deal. In contrast, if the
63f275
amount of files grows, updating the copyright and license note for all
63f275
of them would be a task rather tedious. The shell functionality
63f275
exists to solve maintainance tasks just as the one previously
63f275
mentioned.
63f275

63f275

When you use shell functionality to update copyright inside

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

63f275
 1| #!/bin/bash
63f275
 2| #
63f275
 3| # doSomething.sh -- The function description goes here.
63f275
 4| # 
63f275
 5| # Copyright
63f275
 6| #
63f275
 7| # ...
63f275
 8| #
63f275
 9| # ----------------------------------------------------------------------
63f275
10| # $Id$
63f275
11| # ----------------------------------------------------------------------
63f275
12|
63f275
13| function doSomething {
63f275
14|     
63f275
15| }
63f275
63f275

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

63f275
Everything else in the file is left immutable.
63f275

63f275

When you are updating copyright through shell

63f275
functionality,  the <tt>`centos-art.sh'</tt> script replaces everything
63f275
in-between line 5 --the first one matching <samp>`^# Copyright .+$'</samp>
63f275
string-- and line 9--the first long dash separator matching <samp>`^#
63f275
-+$'</samp>-- with the content of copyright template instance.
63f275

63f275
Caution

Caution

Be sure to add the long dash separator that matches

63f275
<samp>`^# -+$'</samp> regular expression before the function
63f275
definition. Otherwise, if the <samp>`Copyright'</samp> line is present but no
63f275
long dash separator exists, <tt>`centos-art.sh'</tt> will remove anything
63f275
in-between the <samp>`Copyright'</samp> line and the end of file. This way you
63f275
may lost your function definitions entirely.
63f275

63f275
63f275

The copyright template instance is created from one copyright template

63f275
stored in the <tt>`Config/tpl_forCopyright.sed'</tt> file.  The template
63f275
instance is created once, and later removed when no longer needed. At
63f275
this moment, when template instance is created, the
63f275
<tt>`centos-art.sh'</tt> script takes advantage of automation in order to
63f275
set copyright full name and date dynamically.
63f275

63f275

When you use shell functionality to update copyright, the first

63f275
thing <tt>`shell'</tt> functionality does is requesting copyright
63f275
information to user, and later, if values were left empty (i.e., no
63f275
value was typed before pressing RET key), the <tt>`shell'</tt>
63f275
functionality uses its own default values.
63f275

63f275

When shell functionality uses its own default values, the final

63f275
copyright note looks like the following:
63f275

63f275
 1| #!/bin/bash
63f275
 2| #
63f275
 3| # doSomthing.sh -- The function description goes here.

63f275
26| function doSomething {
63f275
27|
63f275
28| }
63f275
63f275

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

63f275
attention how the copyright line was built, and how the license was
63f275
added into the top comment where previously was just three dots.
63f275
Everything else in the file was left immutable. 
63f275

63f275

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

63f275
run the shell functionality over the root directory containing
63f275
the script files you want to update copyright in and enter the
63f275
appropriate information when it be requested. You can run the
63f275
shell functionality as many times as you need to.
63f275

63f275

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

63f275
20), you need to edit the <tt>`Config/tpl_forCopyright.sed'</tt> file, set
63f275
the appropriate information, and run the shell functionality
63f275
once again for changes to take effect over the files you specify.

3.44.3 Usage

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

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

63f275
under <samp>`path/to/dir'</samp> directory. 
63f275

63f275
2c8180
63f275

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

63f275
to process is reduced as specified in <samp>`regex'</samp> regular expression.
63f275
Inside <tt>`centos-art.sh'</tt> script, the <samp>`regex'</samp> regular
63f275
expression is used in combination with find command to look
63f275
for files matching the regular expression path pattern.
63f275

63f275
Warning

Warning

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

63f275
a file, the <samp>`regex'</samp> regular expresion must match the whole file
63f275
path not just the file name. 
63f275

2c8180
63f275

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

63f275
inside <tt>`path/to/dir'</tt>, use the .+/render.conf regular
63f275
expression.  Later, <tt>`centos-art.sh'</tt> script uses this value inside
63f275
^$REGEX\.sh$ expression in order to build the final regular
63f275
expression (i.e., ^.+/render.conf\.sh$) that is evaluated
63f275
against available file paths inside the list of files to process.
63f275

63f275

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

63f275
that <samp>`regex'</samp>, appended to <samp>`path/to/dir/'</samp> (i.e.
63f275
<samp>`path/to/dir/regex'</samp>), matches a regular file; the
63f275
<tt>`centos-art.sh'</tt> script uses the file matching as only file in the
63f275
list of files to process.
