<H1 CLASS="title">Translating and Customizing CUPS</H1>

<P>Thanks to its extensive use of templates, images, and message
catalogs, CUPS can be easily translated (or customized!) to suit
your needs. This help file will guide you through the CUPS
localization files so you can get the most out of it.</P>


<H2 CLASS="title"><A NAME="INTRO">Getting Started</A></H2>

<P>Start by downloading the CUPS source code from <A
HREF="http://www.cups.org/software.php"
TARGET="_blank">www.cups.org</A>. After you extract the files
from the source archive, you will want to copy the following
files and directories:</P>

<UL>

	<LI><VAR>desktop/cups.desktop</VAR> - the GNOME/KDE
	desktop file pointing to the CUPS web interface</LI>

	<LI><VAR>doc/index.html</VAR> - the web interface home
	page</LI>

	<LI><VAR>locale/cups.pot</VAR> - the message catalog</LI>

	<LI><VAR>templates/*.tmpl</VAR> - the web interface
	template files</LI>
	
</UL>

<P>With the exception of the message catalogs and desktop file,
localization files are  placed in subdirectories under the
<VAR>doc</VAR> and <VAR>templates</VAR> using the locale name.
Locale names are either <VAR>ll</VAR> or <VAR>ll_CC</VAR>, where
"ll" is the 2-letter language code and "CC" is the 2-letter
country code. <em>CUPS does not currently use or support the newer
<VAR>ll-region</VAR> syntax for locale names.</em></P>

<P>All non-image files must be encoded using the UTF-8 character
set.</P>


<H2 CLASS="title"><A NAME="SUBMIT">Submitting a Translation for CUPS</A></H2>

<P>To submit a translation for inclusion in CUPS, translate the
desktop file, all of the template files, the <VAR>index.html.in</VAR>
file, and the message catalog. Place these files in the correct
subdirectories in the CUPS source code archive and run the following
command to create an archive with your files:</P>

<PRE CLASS="command">
tar cvf <I>ll_CC</I>.tar.gz desktop/cups.desktop doc/<I>ll_CC</I> \
    locale/cups_<I>ll_CC</I>.po templates/<I>ll_CC</I>
</PRE>

<P>Replace "ll_CC" with the locale name for your translation.
Once you have created the archive, go to the <A
HREF="http://www.cups.org/str.php" TARGET="_blank">CUPS Bugs
&amp; Features</A> page and submit a bug report, attaching the
translation to the report.</P>


<H2 CLASS="title"><A NAME="DESKTOP">The Desktop File</A></H2>

<P>The <VAR>desktop/cups.desktop</VAR> file provides a link to
the CUPS web interface from desktop environments such as
GNOME and KDE. To translate this file, add two lines to the
bottom with the <tt>Name</tt> and <tt>Comment</tt> keys:</P>

<PRE CLASS="command">
Name[<I>ll_CC</I>]=<I>Translation of "Manage Printing"</I>
Comment[<I>ll_CC</I>]=<I>Translation of "CUPS Web Interface"</I>
</PRE>


<H2 CLASS="title"><A NAME="HOMEPAGE">The Home Page</A></H2>

<P>The <VAR>index.html</VAR> file is a complete HTML file that is
displayed when the user visits "http://localhost:631/". Edit the
existing <VAR>doc/index.html</VAR> and save it in the
<VAR>doc/ll_CC</VAR> subdirectory so that the makefile can
install it. Run "make install" in the <VAR>doc</VAR> subdirectory
to test the new home page.</P>


<H2 CLASS="title"><A NAME="CATALOGS">Message Catalogs</A></H2>

<P>CUPS message catalogs are GNU gettext ".po" text files that
provide a list of localized message strings for the CUPS
software. Message catalogs are named <VAR>cups_ll.po</VAR> or
<VAR>cups_ll_CC.po</VAR>, where "ll" is the standard 2-letter
abbreviation for the language and "CC" is the standard 2-letter
abbreviation for the country.</P>

<P>When translating a new message catalog, copy the
<VAR>cups.pot</VAR> message catalog file in the <VAR>locale</VAR>
subdirectory of the CUPS source code. For example, to start
translating the message catalog to Canadian French, you would
type the following commands:</P>

<PRE CLASS="command">
cd locale
cp cups.pot cups_fr_CA.po
</PRE>

<P>Alternatively, you can copy the existing <VAR>cups_fr.po</VAR>
message catalog and then make any necessary changes.</P>

<P>Once you have make your copy of the file, edit it using your
favorite text editor or translation program to translate the text
to the desired language.</P>

<P>Then validate your translation using the <VAR>locale/checkpo</VAR> utility:</P>

<PRE CLASS="command">
cd locale
./checkpo cups_ll_CC.po
</PRE>

<P>After fixing any errors in your translation, add your locale to the <CODE>LANGUAGES</CODE>
variable in the <VAR>Makedefs</VAR> file and run the "make
install" command in the <VAR>locale</VAR> subdirectory to test
the translation.</P>


<H2 CLASS="title"><A NAME="TEMPLATES">Template Files</A></H2>

<P>The CUPS scheduler provides a web interface that can be used
to do many common printing and administration tasks. The built-in
web server supports localization of web pages through the use of
subdirectories for each locale, e.g. "fr" for French, "de" for
German, "fr_ca" for French in Canada, and so forth.</P>

<P>Template files are HTML files with special formatting
characters in them that allow substitution of variables and arrays.
The CUPS CGI programs (<CODE>admin.cgi</CODE>,
<CODE>classes.cgi</CODE>, <CODE>help.cgi</CODE>,
<CODE>jobs.cgi</CODE>, and <CODE>printers.cgi</CODE>) use these
template file to provide dynamic content for the web interface.
Template files are installed in the
<VAR>/usr/share/cups/templates</VAR> directory by default. Table
2 lists the various template files and their purpose.</P>

<P>Translated versions of the template files should be saved in
the <VAR>templates/ll_CC</VAR> subdirectory. For example,
Canadian French template files should be saved in the
<VAR>templates/fr_CA</VAR> subdirectory. After you have
translated all of the templates, add the locale to the
<CODE>LANGUAGES</CODE> variable in the
<VAR>Makedefs</VAR> file and run "make install" in the
<VAR>templates</VAR> subdirectory to test the translation.</P>

</TABLE></DIV>

<H3><A NAME="VARIABLE">Inserting Attributes and Values</A></H3>

<P>Template files consist of HTML with variable substitutions for
named inside curly braces "{name}". Variable names are generally
the IPP attribute names with the hyphen ("-") replaced by the
underscore ("_") character. For example, the
<TT>job-printer-uri</TT> attribute is renamed to
<TT>job_printer_uri</TT>.</P>

<P>Curley braces ("{" and "}") to indicate substitutions, and the
backslash ("\") character for quoting. To insert any of these
special characters as-is you need to use the HTML
<CODE>&amp;name;</CODE> mechanism or prefix each special
character with the backslash ("\".)</P>

<P>You substitute the value of a variable using
<CODE>{NAME}</CODE> in your template file. If the variable is
undefined then the <CODE>{NAME}</CODE> string is output
as-is.</P>

<P>To substitute an empty string if the variable is undefined,
use <CODE>{?NAME}</CODE> instead.</P>

<H3>Array Substitutions</H3>

<P>The number of array elements can be inserted using
<CODE>{#NAME}</CODE>. If the array is undefined then 0 is output.
The current array element (starting at 1) is inserted with
<CODE>{#}</CODE>.</P>

<P>Arrays are handled using <CODE>{[NAME]</CODE> at the beginning
of a section and <CODE>}</CODE> at the end. The information
between the closing bracket ("]") and closing brace ("}") is
repeated for as many elements as are in the named array. For
example, the following template will display a list of each job
in the <CODE>job_id</CODE> array:</P>

<PRE CLASS="command">
&lt;TABLE&gt;
&lt;TR&gt;
	&lt;TH&gt;Job ID&lt;/TH&gt;
	&lt;TH&gt;Destination&lt;/TH&gt;
	&lt;TH&gt;Title&lt;/TH&gt;
&lt;/TR&gt;

{[job_id]
&lt;TR&gt;
	&lt;TD&gt;{?job_id}&lt;/TD&gt;
	&lt;TD&gt;{?job_printer_name}&lt;/TD&gt;
	&lt;TD&gt;{?job_name}&lt;/TD&gt;
&lt;/TR&gt;
}
&lt;/TABLE&gt;
</PRE>

<P>Arrays can be nested, however all elements within the curly
braces ("{" and "}") are indexed using the innermost array.</P>

<H3>Conditional Tests</H3>

<P>Templates can also test variables against specific values and
conditionally include text in the template. The format is:</P>

<PRE CLASS="command">
{<I>variable</I>?<I>true</I>:<I>false</I>}
{<I>variable</I>=<I>value</I>?<I>true</I>:<I>false</I>}
{<I>variable</I>!<I>value</I>?<I>true</I>:<I>false</I>}
{<I>variable</I>&lt;<I>value</I>?<I>true</I>:<I>false</I>}
{<I>variable</I>><I>value</I>?<I>true</I>:<I>false</I>}
</PRE>

<P>where <VAR>true</VAR> is the text that is included if the
condition is true and <VAR>false</VAR> is the text that is
included if the condition is false. A value of <CODE>#</CODE> is
replaced with the current element number (starting at 1.) The
character after the variable name specifies the condition to
test. Table 3 shows the available test conditions.</P>

<CODE>FIRST</CODE> for the first class, job, or printer to
