3.55.1 Goals
|
|
|
ee1f37 |
|
|
|
ee1f37 |
This section exists to organize files related to shell
|
|
|
ee1f37 |
functionality of <tt>`centos-art.sh'</tt> script.
|

|

3.55.2 Description
|
|
|
ee1f37 |
|
|
|
ee1f37 |
The shell functionality of <tt>`centos-art.sh'</tt> script helps
|
|
|
ee1f37 |
you to maintain bash scripts inside repository. For example, suppose
|
|
|
ee1f37 |
you've created many functionalities for <tt>`centos-art.sh'</tt> script,
|
|
|
ee1f37 |
and you want to use a common copyright and license note for
|
|
|
ee1f37 |
consistency in all your script files. If you have a bunch of files,
|
|
|
ee1f37 |
doing this one by one wouldn't be a big deal. In contrast, if the
|
|
|
ee1f37 |
amount of files grows, updating the copyright and license note for all
|
|
|
ee1f37 |
of them would be a task rather tedious. The shell functionality
|
|
|
ee1f37 |
exists to solve maintainance tasks just as the one previously
|
|
|
ee1f37 |
mentioned.
|
|
|
ee1f37 |
|
|
|
ee1f37 |
When you use shell functionality to update copyright inside
|
|
|
ee1f37 |
script files, it is required that your script files contain (at least)
|
|
|
ee1f37 |
the following top commentary structure:
|
|
|
ee1f37 |
|
|
|
ee1f37 |
|
|
|
ee1f37 |
1| #!/bin/bash
|
|
|
ee1f37 |
2| #
|
|
|
ee1f37 |
3| # doSomething.sh -- The function description goes here.
|
|
|
ee1f37 |
4| #
|
|
|
ee1f37 |
5| # Copyright
|
|
|
ee1f37 |
6| #
|
|
|
ee1f37 |
7| # ...
|
|
|
ee1f37 |
8| #
|
|
|
ee1f37 |

|
|
|
ee1f37 |

|
ee1f37 |

|
|
|
ee1f37 |
12|
|
|
|
ee1f37 |
13| function doSomething {
|
|
|
ee1f37 |
14|
|
|
|
ee1f37 |
15| }
|
|
|
ee1f37 |
|
|
|
ee1f37 |
Figure 3.4: The functions script base comment structure
|
|
|
ee1f37 |
|
|
|
ee1f37 |
|
|
|
ee1f37 |
Relevant lines in the above structure are lines from 5 to 9.
|
|
|
ee1f37 |
Everything else in the file is left immutable.
|
|
|
ee1f37 |
|
|
|
ee1f37 |
When you are updating copyright through shell
|
|
|
ee1f37 |
functionality, the <tt>`centos-art.sh'</tt> script replaces everything
|
|
|
ee1f37 |
in-between line 5 --the first one matching <samp>`^# Copyright .+$'</samp>
|
|
|
ee1f37 |
string-- and line 9--the first long dash separator matching <samp>`^#
|
|
|
ee1f37 |
-+$'</samp>-- with the content of copyright template instance.
|
|
|
ee1f37 |
|
|
|
ee1f37 |
 Caution Be sure to add the long dash separator that matches
|
|
|
ee1f37 |
<samp>`^# -+$'</samp> regular expression before the function
|
|
|
ee1f37 |
definition. Otherwise, if the <samp>`Copyright'</samp> line is present but no
|
|
|
ee1f37 |
long dash separator exists, <tt>`centos-art.sh'</tt> will remove anything
|
|
|
ee1f37 |
in-between the <samp>`Copyright'</samp> line and the end of file. This way you
|
|
|
ee1f37 |
may lost your function definitions entirely.
|
|
|
ee1f37 |
|
|
|
ee1f37 |
|
|
|
ee1f37 |
The copyright template instance is created from one copyright template
|
|
|
ee1f37 |
stored in the <tt>`Config/tpl_forCopyright.sed'</tt> file. The template
|
|
|
ee1f37 |
instance is created once, and later removed when no longer needed. At
|
|
|
ee1f37 |
this moment, when template instance is created, the
|
|
|
ee1f37 |
<tt>`centos-art.sh'</tt> script takes advantage of automation in order to
|
|
|
ee1f37 |
set copyright full name and date dynamically.
|
|
|
ee1f37 |
|
|
|
ee1f37 |
When you use shell functionality to update copyright, the first
|
|
|
ee1f37 |
thing <tt>`shell'</tt> functionality does is requesting copyright
|
|
|
ee1f37 |
information to user, and later, if values were left empty (i.e., no
|
|
|
ee1f37 |
value was typed before pressing RET key), the <tt>`shell'</tt>
|
|
|
ee1f37 |
functionality uses its own default values.
|
|
|
ee1f37 |
|
|
|
ee1f37 |
When shell functionality uses its own default values, the final
|
|
|
ee1f37 |
copyright note looks like the following:
|
|
|
ee1f37 |
|
|
|
ee1f37 |
|
|
|
ee1f37 |
1| #!/bin/bash
|
|
|
ee1f37 |
2| #
|
|
|
ee1f37 |
3| # doSomthing.sh -- The function description goes here.

Figure 3.5: The function script comment example
|
|
|
ee1f37 |
|
|
|
ee1f37 |
|
|
|
ee1f37 |
Relevant lines in the above structure are lines from 5 to 22. Pay
|
|
|
ee1f37 |
attention how the copyright line was built, and how the license was
|
|
|
ee1f37 |
added into the top comment where previously was just three dots.
|
|
|
ee1f37 |
Everything else in the file was left immutable.
|
|
|
ee1f37 |
|
|
|
ee1f37 |
To change copyright information (i.e., full name or year information),
|
|
|
ee1f37 |
run the shell functionality over the root directory containing
|
|
|
ee1f37 |
the script files you want to update copyright in and enter the
|
|
|
ee1f37 |
appropriate information when it be requested. You can run the
|
|
|
ee1f37 |
shell functionality as many times as you need to.
|
|
|
ee1f37 |
|
|
|
ee1f37 |
To change copyright license (i.e., the text in-between lines 7 and
|
|
|
ee1f37 |
20), you need to edit the <tt>`Config/tpl_forCopyright.sed'</tt> file, set
|
|
|
ee1f37 |
the appropriate information, and run the shell functionality
|
|
|
ee1f37 |
once again for changes to take effect over the files you specify.

3.55.3 Usage
|
|
|
ee1f37 |
|
|
|
ee1f37 |
|
|
|
ee1f37 |
centos-art sh --update-copyright='path/to/dir'
|
|
|
ee1f37 |
centos-art sh --update-copyright='path/to/dir' --filter='regex'
|
|
|
ee1f37 |
Use these commands to update copyright information in <samp>`.sh'</samp> files
|
|
|
ee1f37 |
under <samp>`path/to/dir'</samp> directory.
|
|
|
ee1f37 |
|
|
|
ee1f37 |
|
|
|
ee1f37 |
|
|
|
ee1f37 |
When you provide <samp>`--filter='regex''</samp> argument, the list of files
|
|
|
ee1f37 |
to process is reduced as specified in <samp>`regex'</samp> regular expression.
|
|
|
ee1f37 |
Inside <tt>`centos-art.sh'</tt> script, the <samp>`regex'</samp> regular
|
|
|
ee1f37 |
expression is used in combination with find command to look
|
|
|
ee1f37 |
for files matching the regular expression path pattern.
|
|
|
ee1f37 |
|
|
|
ee1f37 |
 Warning In order for <samp>`regex'</samp> regular expression to match
|
|
|
ee1f37 |
a file, the <samp>`regex'</samp> regular expresion must match the whole file
|
|
|
ee1f37 |
path not just the file name.
|
|
|
ee1f37 |
|
|
|
ee1f37 |
|
|
|
ee1f37 |
For example, if you want to match all <tt>`render.conf.sh'</tt> files
|
|
|
ee1f37 |
inside <tt>`path/to/dir'</tt>, use the .+/render.conf regular
|
|
|
ee1f37 |
expression. Later, <tt>`centos-art.sh'</tt> script uses this value inside
|
|
|
ee1f37 |
^$REGEX\.sh$ expression in order to build the final regular
|
|
|
ee1f37 |
expression (i.e., ^.+/render.conf\.sh$) that is evaluated
|
|
|
ee1f37 |
against available file paths inside the list of files to process.
|
|
|
ee1f37 |
|
|
|
ee1f37 |
Exceptionally, when you provide <samp>`--filter='regex''</samp> in the way
|
|
|
ee1f37 |
that <samp>`regex'</samp>, appended to <samp>`path/to/dir/'</samp> (i.e.
|
|
|
ee1f37 |
<samp>`path/to/dir/regex'</samp>), matches a regular file; the
|
|
|
ee1f37 |
<tt>`centos-art.sh'</tt> script uses the file matching as only file in the
|
|
|
ee1f37 |
list of files to process.
