3.44.1 Goals

54b5a5
60c152

This section exists to organize files related to svg

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

3.44.2 Description

54b5a5
60c152

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

60c152
to maintain scalable vector graphics (SVG) inside repository. For
60c152
example, suppose you've been working in CentOS default design models
60c152
under <tt>`trunk/Identity/Themes/Models/'</tt>, and you want to set common
60c152
metadata to all of them, and later remove all unused SVG defintions
60c152
from <samp>`*.svg'</samp> files. Doing so file by file may be a tedious task,
60c152
so the <tt>`centos-art.sh'</tt> script provides the svg
60c152
functionality to aid you maintain such actions.

3.44.2.1 Metadata maintainance

60c152
60c152

The metadata used is defined by Inkscape 0.46 using the SVG standard

60c152
markup. The <tt>`centos-art.sh'</tt> script replaces everything
60c152
in-between <metadata and </metadata> tags with a
60c152
predefined metadata template we've set for this purpose.
e68a7a

60c152

The metadata template was created using the metadata information of a

60c152
file which, using Inkscape 0.46, all metadata fields were set. This
60c152
created a complete markup representation of how SVG metadata would
60c152
look like. Later, we replaced every single static value with a
60c152
translation marker in the form <samp>`=SOMETEXT='</samp>, where
60c152
SOMETEXT is the name of its main opening tag. Later, we
60c152
transform the metadata template into a sed replacement set of commads
60c152
escaping new lines at the end of each line.
e68a7a

60c152

With metadata template in place, the <tt>`centos-art.sh'</tt> script uses

60c152
it to create a metadata template instance for the file being processed
60c152
currently.  The metadata template instance contains the metadata
60c152
portion of sed replacement commands with translation markers already
60c152
traduced.  In this action, instance creation, is where we take
60c152
advantage of automation and generate metadata values like title, date,
60c152
keywords, source, identifier, and relation dynamically, based on the
60c152
file path <tt>`centos-art.sh'</tt> script is currently creating metadata
60c152
information for.
63f275

60c152

With metadata template instance in place, the <tt>`centos-art.sh'</tt>

60c152
script uses it to replace real values inside all <samp>`.svg'</samp> files
60c152
under the current location you're running the <tt>`centos-art.sh'</tt>
60c152
script on.  Default behaviour is to ask user to enter each metadatum
60c152
required, one by one. If user leaves metadatum empty, by pressing
60c152
RET key, <tt>`centos-art.sh'</tt> uses its default value.
60c152

60c152

The <tt>`centos-art.sh'</tt> script modifies the following metadata:

60c152

60c152
60c152
<samp>`Title'</samp>
60c152

The <samp>`License'</samp> metadatum is not set as a choise, by now. It is

60c152
fixed Creative Common Attribution Share-Alike 3.0 License. This is done in order to

grant license consistency among all SVG files we manage inside CentOS

3.44.2.2 Unused definitions

e68a7a
60c152

As SVG files grow they may end up with unused definitions inside. For

60c152
example, if you stop using a pattern or gradient, tags used to define
60c152
them are considered unused definitions then. Inkscape 0.46 brings the
60c152
<samp>`Vaccum Defs'</samp> feature to remove those unused definitions from SVG
60c152
files. The <samp>`Vaccum Defs'</samp> feature is available both at graphical
60c152
interface and command line interface.
60c152

60c152

If you have one or two couple of files, removing unused SVG

60c152
definitions using graphical interface may be enough to you.  In
60c152
contrast, if you have houndred of files to maintain it is not a fun
60c152
task to use the gui interface to remove unused SVG definitions editing
60c152
those files one by one.
60c152

60c152

To remove unused SVG definitions from several SVG files, the

60c152
<tt>`centos-art.sh'</tt> script uses Inkscape's command-line interface,
60c152
specifically with the <samp>`--vaccum-defs'</samp> option.
60c152

3.44.3 Usage

008ee0
63f275
60c152
centos-art svg --update-metadata='path/to/dir'
60c152
centos-art svg --update-metadata='path/to/dir' --filter='regex'
60c152

Use these commands to update metadata information to <samp>`.svg'</samp> files

60c152
under <samp>`path/to/dir'</samp> directory.
60c152

60c152
60c152
centos-art svg --vacuum-defs='path/to/dir'
60c152
centos-art svg --vacuum-defs='path/to/dir' --filter='regex'
60c152

Use these commands to remove unused definitions inside <samp>`.svg'</samp>

60c152
files 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
60c152

For example, if you want to match all <tt>`summary.svg'</tt> files inside

60c152
<tt>`path/to/dir'</tt>, use the .+/summary regular expression.
60c152
Later, <tt>`centos-art.sh'</tt> script uses this value inside
60c152
^$REGEX\.svg$ expression in order to build the final regular
60c152
expression (i.e., ^.+/summary\.svg$) that is evaluated against
60c152
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.
