This section exists to organize files related to svg
functionality of `centos-art.sh' script.
The svg functionality of `centos-art.sh' script helps you
to maintain scalable vector graphics (SVG) inside repository. For
example, suppose you've been working in CentOS default design models
under `trunk/Identity/Themes/Models/', and you want to set common
metadata to all of them, and later remove all unused SVG defintions
from `*.svg' files. Doing so file by file may be a tedious task,
so the `centos-art.sh' script provides the svg
functionality to aid you maintain such actions.
The metadata used is defined by Inkscape 0.46 using the SVG standard
markup. The `centos-art.sh' script replaces everything
in-between <metadata and </metadata> tags with a
predefined metadata template we've set for this purpose.
The metadata template was created using the metadata information of a
file which, using Inkscape 0.46, all metadata fields were set. This
created a complete markup representation of how SVG metadata would
look like. Later, we replaced every single static value with a
translation marker in the form `=SOMETEXT=', where
SOMETEXT is the name of its main opening tag. Later, we
transform the metadata template into a sed replacement set of commads
escaping new lines at the end of each line.
With metadata template in place, the `centos-art.sh' script uses it to create a metadata template instance for the file being processed currently. The metadata template instance contains the metadata portion of sed replacement commands with translation markers already traduced. In this action, instance creation, is where we take advantage of automation and generate metadata values like title, date, keywords, source, identifier, and relation dynamically, based on the file path `centos-art.sh' script is currently creating metadata information for.
With metadata template instance in place, the `centos-art.sh' script uses it to replace real values inside all `.svg' files under the current location you're running the `centos-art.sh' script on. Default behaviour is to ask user to enter each metadatum required, one by one. If user leaves metadatum empty, by pressing RET key, `centos-art.sh' uses its default value.
The `centos-art.sh' script modifies the following metadata:
Name by which this document is formally known. If no value is set here, `centos-art.sh' script uses the file name as title.
Date associated with the creation of this document (YYYY-MM-DD). If no
value is set here, `centos-art.sh' script uses the current date
information as in date +%Y-%m-%d.
Name of entity primarily responsible for making the content of this document. If no value is set here, `centos-art.sh' script uses the string `The CentOS Project'.
Name of entity with rights to the intellectual Property of this document. If no value is set here, `centos-art.sh' script uses the string `The CentOS Project'.
Name of entity responsible for making this document available. If no value is set here, `centos-art.sh' script uses the string `The CentOS Project'.
Unique URI to reference this document. If no value is set here, `centos-art.sh' script uses the current file path to build the related url that points to current file location inside repository central server.
Unique URI to reference the source of this document. If no value is set here, `centos-art.sh' script uses current file path to build the related url that points to current file location inside repository central server.
Unique URI to a related document. If no value is set here, `centos-art.sh' script uses current file path to build the related url that points to current file location inside repository central server.
Two-letter language tag with optional subtags for the language of this
document. (e.g. `en-GB'). If no value is set here,
`centos-art.sh' script uses the current locale information as in
cli_getCurrentLocale function.
The topic of this document as comma-separated key words, prhases, or classifications. If no value is set here, `centos-art.sh' script uses file path to build
Extent or scope of this document. If no value is set here, `centos-art.sh' script uses the string `The CentOS Project'.
Description about the document. If no value is set here, `centos-art.sh' script uses uses empty value as default.
People that contributes in the creation/maintainance of the document. If no value is set here, `centos-art.sh' script uses uses empty value as default.
The `License' metadatum is not set as a choise, by now. It is 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 Artwork Repository.
Many of the no-longer-used gradients, patterns, and markers (more precisely, those which you edited manually) remain in the corresponding palettes and can be reused for new objects. However if you want to optimize your document, use the `Vacuum Defs' command in `File' menu. It will remove any gradients, patterns, or markers which are not used by anything in the document, making the file smaller.
If you have one or two couple of files, removing unused definitions using the graphical interface may be enough to you. In contrast, if you have dozens or even houndreds of scalable vector graphics files to maintain it is not a fun task to use the graphical interface to remove unused definitions editing those files one by one.
To remove unused definitions from several scalable vector graphics files, the `centos-art.sh' script uses Inkscape command-line interface, specifically with the `--vaccum-defs' option.
centos-art svg --update-metadata='path/to/dir'centos-art svg --update-metadata='path/to/dir' --filter='regex'Use these commands to update metadata information to `.svg' files under `path/to/dir' directory.
centos-art svg --vacuum-defs='path/to/dir'centos-art svg --vacuum-defs='path/to/dir' --filter='regex'Use these commands to remove unused definitions inside `.svg' files under `path/to/dir' directory.
When you provide `--filter='regex'' argument, the list of files
to process is reduced as specified in `regex' regular expression.
Inside `centos-art.sh' script, the `regex' regular
expression is used in combination with find command to look
for files matching the regular expression path pattern.
Warning
In order for `regex' regular expression to match a file, the `regex' regular expresion must match the whole file path not just the file name.
For example, if you want to match all `summary.svg' files inside
`path/to/dir', use the .+/summary regular expression.
Later, `centos-art.sh' script uses this value inside
^$REGEX\.svg$ expression in order to build the final regular
expression (i.e., ^.+/summary\.svg$) that is evaluated against
available file paths inside the list of files to process.
Exceptionally, when you provide `--filter='regex'' in the way that `regex', appended to `path/to/dir/' (i.e. `path/to/dir/regex'), matches a regular file; the `centos-art.sh' script uses the file matching as only file in the list of files to process.
