<title>Document Type Editing Package (&DTEP;)</title>

<para>
Document Type Editing Packages (&DTEP;s) are used in &quantaplus; to add
support for markup, scripting languages, and &CSS;. They allow
&quantaplus; to provide features like auto-completion and node trees.
Their simplicity and flexibility are what make &quantaplus; a fast,
developer friendly &IDE; for web developers. They are what make &quantaplus;
an easy-to-use, productive environment.
</para>

<para>
&DTEP;s come in two flavors, Family 1, which are markups, and Family 2,
which are scripting and &CSS;. &DTEP;s are made up of two parts, the Tag
Folder and the Toolbars. Tag Folders are composed of two types of files,
the &descriptionrc; and TagXML files, which carry the extension .tag.
Toolbars are the handy, icon-oriented tabs of buttons (above the editing
window) which place text into a document faster than the user can type.
</para>

<para>
  &DTEP;s can be created manually (see below), <link linkend="download-resources">downloaded</link> or automatically created from an existing DTD. See <xref linkend="converting-dtd" /> for details about the conversion.
</para>

<para>
This document describes how to make TagXML files, the &descriptionrc;, and
toolbars. In short, a &DTEP;.
</para>

<para>
TagXML files (.tag) define both the attributes specific to a tag and the
layout and contents of the properties dialog &quantaplus; shows for the tag.
The &descriptionrc; file provides rules and information on the &DTEP;
itself. Toolbars provide a quick means for adding tags into a document
without worry of mis-spellings and such.
</para>

<sect2 id="dtep-packaging-3-2">
<title>Packaging</title>

<para>
Tag Folders are just that, folders. They are composed only of the
&descriptionrc; and TagXML files. Tag Folders carry the name of the mark-up
language and version, if applicable. (For example, html-4.01-strict)
</para>
</sect2>

<sect2 id="tagxml-3-2">
<title>TagXML</title>

<para>
The table below lists the elements defined in TagXML and declares whether
they are required or not. While not all are required, it is recommended
that you use as many as you can so that other users can have a better
experience and more information to work with.

<sect1 id="user-actions">
<title>User Defined Actions</title>
<para>
Actions are very common in every application. You meed them often when you use any application. Clicking on a toolbar icon, selecting a menu item or using a shortcut usually executes an action. In &quantaplus; actions are taken to the next level. Instead of hardcoded actions (that are created by the application
programmer at the source code level) it is possible for the ordinary user to create and modify actions and by this way adding
new functionality to &quantaplus;. These are the user defined actions, and many of the standard &quantaplus; actions are user defined (and user modifiable) actions as well.
</para>
<para>There are three types of user definable actions:
<itemizedlist>
<listitem><para><link linkend="text-actions">Text actions</link></para></listitem>
<listitem><para><link linkend="tag-actions">Tag actions</link></para></listitem>

<sect2 id="creating-actions">

 You can create an action by going to
<menuchoice>

</para>
</sect2>
<sect2 id="script-actions">
<title>Script actions</title>
<para>
<mediaobject><imageobject>
<imagedata fileref="script-action.png" format="PNG" />
</imageobject></mediaobject>
 The most powerful action type. With the help of this action you
can run external applications (usually scripts, but it's
not limited to scripts), which can alter your document or use your document (or part of your document) as input. Examples from &quantaplus; itself are the <guibutton>Quick Start</guibutton> dialog, the various <guilabel>View In...</guilabel> actions for the (X)HTML DTEPs.
</para>
<para>
First you have to enter the name of your script with the interpreter as well. Example:
<command>sh /home/myHome/myScript.sh</command>.
</para>
<para>
Although you can use full paths, the recommended way is to use the <command>%scriptdir</command> variable in the command line, like <command>sh %scriptdir/myScript.sh</command>. This way &quantaplus; will try to locate your script in the following places:
<itemizedlist>
<listitem><para>global script folder: <filename><envar>$TDEDIR</envar>/share/apps/quanta/scripts</filename></para></listitem>
<listitem><para>local script folder: <filename><envar>$TDEHOME</envar>/share/apps/quanta/scripts</filename></para></listitem>
<listitem><para>your path: <envar>$PATH</envar></para></listitem>
</itemizedlist>
There are other special variables that you can use in the command line:
<itemizedlist>
<listitem><para><command>%f</command>: will be replaced with the URL of the current document. In case of local documents, file:/ will be stripped from the document.</para></listitem>
<listitem><para><command>%input</command>: will be replaced with the selected input. See below.</para></listitem>
<listitem><para><command>%projectbase</command>: will be replaced with the URL of the current project. It is empty if no project is loaded.</para></listitem>
<listitem><para><command>%pid</command>: will be replaced with the PID of the running &quantaplus; process. If &quantaplus; is running in unique mode, the "unique " text will be prepended to the PID number. Useful when you use DCOP to control &quantaplus; from the external script.</para></listitem>
<listitem><para><command>%userarguments</command>: useful in case of events. This entry will be replaced by the event properties in the following order: <variablelist>
<varlistentry>
<term>First argument</term>
<listitem><para>The unique id of the script</para></listitem>
</varlistentry>
<varlistentry>
<term>Second argument</term>
<listitem><para>the event name</para></listitem>
</varlistentry>
<varlistentry>
<term>Third argument</term>
<listitem><para>the parameters for the event, usually the file name of the current document or the path to the project file.</para></listitem>
</varlistentry>
</variablelist>
 </para></listitem>
</itemizedlist>
</para>
<para>
Aside of the above methods the script can receive input from &quantaplus; on the standard input. In the <guilabel>Input</guilabel> combobox you can select what to send to the standard input. Choices are:
<itemizedlist>
<listitem><para><guilabel>None</guilabel>: nothing is sent to the script.</para></listitem>
<listitem><para><guilabel>Current document</guilabel>: the whole document is sent to the script.</para></listitem>
<listitem><para><guilabel>Selected text</guilabel>: the selected area of the document is sent to the script. Using the <command>%input</command> variable usually makes sense only when using this setting.</para></listitem>
</itemizedlist>
</para>
<para>
Similar to the <guilabel>Input</guilabel> you can catch the output of the executed application. There are two kind of outputs:
<itemizedlist>
<listitem><para>normal output, printed to the standard output;</para>
</listitem>
<listitem><para>error messages, printed to the standard error.</para>
</listitem>
</itemizedlist>
You can specify what should happen with the text printed to the standard output. This can be done by modifying the value of the <guilabel>Output</guilabel> combobox:
<itemizedlist>
<listitem><para><guilabel>None</guilabel>: the output of the application is ignored.</para></listitem>
<listitem><para><guilabel>Insert in cursor position</guilabel>: the output will be inserted in the current document and the cursor position.</para></listitem>
<listitem><para><guilabel>Replace selection</guilabel>: the selected area of the document will be replaced with the output.</para></listitem>
<listitem><para><guilabel>Replace selection</guilabel>: the selected area of the document will be replaced with the output.</para></listitem>
<listitem><para><guilabel>Create a new document</guilabel>: a new document will be created and will contain all the output of the script.</para></listitem>
<listitem><para><guilabel>Replace current document</guilabel>: the entire document will be replaced with the output.</para></listitem>
<listitem><para><guilabel>Message window</guilabel>: the output will appear in the <guilabel>Messages</guilabel> toolview.</para></listitem>
</itemizedlist>
</para>
<para>The choices for the standard error output (<guilabel>Error</guilabel>) are the same as for the normal output.</para>

<sect1 id="creating-toolbars-3-2">
<title>Creating Toolbars</title>

<para>
The following will show you how to create toolbars for a &DTEP;. Toolbars
are graphical elements that are assigned to actions. Actions, in
&quantaplus;, are the basis for nearly all the extensions that
&quantaplus; has and will acquire in the future. The same mechanism that
defines an action in &quantaplus; also enables auto-completion and tag
dialogs. With actions, the limit of what you can do is virtually
limitless.  For means of an example, we will use <ulink
url="http://tidy.sf.net">&HTML; tidy</ulink> on our web pages.
</para>

<sect2 id="from-scratch-to-complete-3-2">
<title>From Scratch to Complete</title>

<para>
To begin, you will need to create a user toolbar. Select
<menuchoice>
<guimenu>Toolbars</guimenu>
<guimenuitem>Add User Toolbar</guimenuitem>
</menuchoice>.
</para>

<para>
If there are many tags for the markup language, it is recommended that you
split up the tags into logical groups. You will need to create a new user
toolbar for each group. In this case, there are not many, so we will be
making one toolbar and naming it with the name of the markup.
</para>

<para>
Once all your toolbars are created, you must add and configure the
actions. To do this, select
<menuchoice>
<guimenu>Settings</guimenu>
<guimenuitem>Configure Actions</guimenuitem>
</menuchoice>
<emphasis>
</emphasis>.
</para>

<para>
The parts of this window are pretty straight forward. Press the
<guibutton>New action</guibutton> button at the bottom of the window to
enter the editing mode.
</para>

<para>
Fill in all of the necessary fields and add the tag to the appropriate
toolbar(s).
</para>

<para>
Complete the rest and, if the tag has attributes and you always plan to
use them, check the <guilabel>Run "Edit tag" dialog if available
</guilabel> box so that you will be prompted every time the action is used.
</para>

<para>
You should now have something much like the following.
</para>

<mediaobject>
<imageobject>
<imagedata fileref="dtep_doc_img7.png" format="PNG" />
</imageobject>
</mediaobject>

<para>
Press the <guibutton>Apply</guibutton> button and you will see the action
added to the toolbar(s) you have selected.
</para>

<mediaobject>
<imageobject>
<imagedata fileref="dtep_doc_img8.png" format="PNG" />
</imageobject>
</mediaobject>

<para>
Egad! That's an awful icon. How will yourself and others remember that
icon goes with that action? Let's replace it before trouble arises.
</para>

<para>
To create an icon that more accurately describes that action, we will be
using &tdeiconedit;. Select it from the &kmenu;, <menuchoice>
<guisubmenu>Graphics</guisubmenu>
<guisubmenu>More Programs</guisubmenu>
</menuchoice> (or where ever your distribution placed it).
</para>

<para>
&tdeiconedit; defaults to the size 32x32 pixels, but we need 22x22. To
change this, select
<menuchoice>
<guimenu>Edit</guimenu>
<guimenuitem>Resize</guimenuitem>
</menuchoice>.
</para>

<para>
Keep in mind that you are creating an icon that will assist in helping not
only yourself to remember which action does what, but also other users of
the &DTEP;.
</para>

<para>
Since the tag I am creating the icon for is called <quote>start,</quote>
I have decided to create a <quote>Start sign.</quote> Using the color green
(green often interpreted as <quote>go,</quote> <quote>start,</quote> or
<quote>proceed</quote>) will, or, at least, should, convey a message
to the user that clicking this action will place the &lt;start&gt; tag in the
current document.
</para>

<mediaobject>
<imageobject>
<imagedata fileref="dtep_doc_img15.png" format="PNG" />
</imageobject>
</mediaobject>

<para>
Now that I am finished with the creation of the icon, I will save it.
</para>

<para>
Once you are done with creating the icon(s), you must associate the icon
with the action. To do this, open
<menuchoice>
<guimenu>Settings</guimenu>
<guimenuitem>Configure Actions</guimenuitem>
</menuchoice> again (in &quantaplus;) and select the action you made
the icon for. Beside the <guilabel>Text</guilabel> field, you will see a
button, click it.
</para>

<para>
Select <guilabel>Other Icons</guilabel> and then click the <guibutton>
Browse</guibutton> button.
</para>

<para>
Goto the folder in which you saved the icon, select the icon, and click
<guibutton>OK</guibutton>.
</para>

<para>
Press the <guibutton>Apply</guibutton> button and either continue to do the
same with the other tags, if any, or click <guibutton>OK</guibutton> to
finish.
</para>

<mediaobject>
<imageobject>
<imagedata fileref="dtep_doc_img18.png" format="PNG" />
</imageobject>
</mediaobject>

<para>
Let us say you would like to add some common &quantaplus; functions to your
toolbar or maybe you think the toolbar would be better off organized in a
different manner with some separators to group the actions. Open the
<guilabel>Configure Toolbars</guilabel> dialog by going
<menuchoice>
<guimenu>Settings</guimenu>
<guimenuitem>Configure Toolbars</guimenuitem>
</menuchoice>. Make sure your toolbar is selected.
</para>

<para>
I will be choosing the separator (top of the left column) for my toolbar.
Once you have selected the item you wish to add to your toolbar, press the
right arrow button. This will add it to your toolbar.
</para>

<mediaobject>
<imageobject>
<imagedata fileref="dtep_doc_img21.png" format="PNG" />
</imageobject>
</mediaobject>

<para>
I think I would like a quick way to access the <guilabel>Konqueror
Preview</guilabel>. I will select it and add it to the toolbar.
</para>

<mediaobject>
<imageobject>
<imagedata fileref="dtep_doc_img22.png" format="PNG" />
</imageobject>
</mediaobject>

<para>
Note how the separator helps in grouping. Someone new to my toolbar might
have thought that the &konqueror; button was like or the opposite of the
start button.
</para>

<mediaobject>
<imageobject>
<imagedata fileref="dtep_doc_img23.png" format="PNG" />
</imageobject>
</mediaobject>

<para>
Apply your changes and, when you are done, press <guibutton>OK</guibutton>
to finish.
</para>

<para>
Ah, look at the fantastic new toolbar! Much more handy now.
</para>

<mediaobject>
<imageobject>
<imagedata fileref="dtep_doc_img24.png" format="PNG" />
</imageobject>
</mediaobject>

<para>
Remember to test your toolbar, by clicking all the buttons, so that you
know the output is correct.
</para>

<mediaobject>
<imageobject>
<imagedata fileref="dtep_doc_img25.png" format="PNG" />
</imageobject>
</mediaobject>

<para>
Now to save the toolbar, we will select
<menuchoice>
<guimenu>Toolbars</guimenu>
<guisubmenu>Save Toolbars</guisubmenu>
<guimenuitem>Save as Local Toolbar</guimenuitem>
</menuchoice>.
</para>

<para>
Save it to the correct folder. Since NeXML does not exist, I will just
have it to the top-level folder, but your toolbar(s) should be saved to
the correct folder. Make sure to adjust your &descriptionrc; to have it
load your toolbar(s) when a new file of that type is created.

<title>Creating Your Own Documentation</title>

<para>
Probably the most notable additions to &quantaplus; for the general user
will be the addition of documentation for the markup or scripting language
that you like best. To that end, this chapter will explain how I create
the &PHP; documentation tree for my personal use.
</para>

<para>
Before starting on creating your own documentation, you may wish to check
out the <ulink url="http://quanta.sf.net/main1.php?contfile=resource">
&quantaplus; repository</ulink> to see if someone else has already done
this set.
</para>

<para>
There are two parts to this process. First, you must obtain the existing
documentation for the markup/scripting/&etc; language that you are after.
Second, you have to create the <filename>docrc</filename> file. The first
is up to you, the second is what we will cover here.
</para>

<para>
The general form of the docrc file is as follows:
</para>

<informalexample>
<literallayout>
#KDE Config File
[Tree]
Doc dir=<replaceable>path, relative to this file, of the documentation html files</replaceable> &eg; php42/
#top level elements
Top Element=<replaceable>Your description for these documentation</replaceable> &eg; &PHP; 4.2 documentation

Section 1=Section1.html
Section 2=#Sec2.1,#Sec2.2,#Sec2.3
Sec2.1=Sec2.1.html
Sec2.2=Sec2.2.html
Sec2.3=Sec2.3.html
...

[Context]
ContextList=func1,func2,tag1,tag2,tag3
func1=func1.html
func2=func2.html
tag1=tag1.html
tag2=tag2.html
tag3=tag3.html
</literallayout>
</informalexample>

<para>
The <filename>docrc</filename> is broken down into two sections: Tree and
Context.
</para>

<para>
The Tree section defines the presentation aspect of the documentation in
the documentation tab. For example, you will see that in the &PHP;
documentation you have something akin to this:
</para>

<mediaobject>
<imageobject>
<imagedata fileref="doc-view1.png" format="PNG" />
</imageobject>
</mediaobject>

<para>
Relating this to the above, my &PHP; <filename>docrc</filename> looks like
this:
</para>

<informalexample>
<literallayout>
#KDE Config File

[Tree]

Doc dir=php42/

#top level elements

<para>
Notice the <literal>#</literal> in front of <quote>Getting Started</quote>
and <quote>Language Reference</quote>. This indicates that these are sub
containers in the tree and have content of their own. I do not believe that
there is a set limit to the depth here (other than that driven by sanity)
&mdash; use your judgment.
</para>

<para>
For the Table of Contents, you will notice that it is referenced directly to
a file (and consequently shows up at the bottom of the tree view &mdash;
folders first!).
</para>

<important>
<para>
Spaces do not adversely affect anything, but watch out for &amp; and &lt;
characters. These should likely be replaced by &amp;amp; and &amp;lt;
respectively in all of the &XML; based &quantaplus; resource files.
</para>
</important>

<para>
The Context section is the section of the docrc file that is used to
facilitate context sensitive help. For example, you are writing a &PHP;
script and you would like to see the documentation for the
<function>mysql_fetch_array</function> function. You simply highlight the
function and then press <keycombo action="simul">&Ctrl;<keycap>H</keycap>
</keycombo> for context help. The documentation on
<function>mysql_fetch_array</function> will immediately display. There are
only two entry types here: the ContextList and the file association lines.
</para>

<variablelist>
<varlistentry>
<term>ContextList</term>
<listitem>
<para>
Really simple, this is just a comma separated list of the context items
you wish to have available (for &PHP;, these are the functions for &PHP;).
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>File association lines</term>
<listitem>
<para>
These are of the form context item=html doc page. &eg;
acos=function.acos.html
</para>
</listitem>
</varlistentry>
</variablelist>

<para>
A pared down version of my <filename>docrc</filename> Context section is
as follows:
</para>

<informalexample>
<literallayout>
#Keywords for context help
[Context]
ContextList=abs,acos,acosh,addcslashes,addslashes,...

abs=function.abs.html
acos=function.acos.html
acosh=function.acosh.html
addcslashes=function.addcslashes.html
addslashes=function.addslashes.html
...
</literallayout>
</informalexample>

<para>
Now you can just save your <filename>docrc</filename> file, save it in
<filename class="directory">$<envar>HOME</envar>/.trinity/share/apps/quanta/doc</filename>
or <filename
class="directory">$<envar>TDEDIR</envar>/share/apps/quanta/doc</filename>
for local or global use respectively. Then create a folder (the one
specified in your <filename>docrc</filename> file) in the same folder
as your <filename>docrc</filename> file and copy your &HTML; pages in
there.
</para>

<para>
You will need to restart &quantaplus; to see your documentation.
</para>

<para>
Once you are sure that they are good and worth sharing, send the <filename>
docrc</filename> file along with a description of any pertinent
information on what documentation you used to the
<ulink url="http://quanta.sf.net/main1.php?contfile=resource">&quantaplus;
repository</ulink> for use by the &quantaplus; community. You will not get
rich, but you will feel great knowing that you contributed to the best web
development platform around.

  <title>Sharing Resources</title>
  <para>With &quantaplus; you are not alone. It is possible to share the various resources (DTEP packages, toolbars with actions, scripts, templates) with others. There are two ways to do it:
  </para>
  <variablelist>
    <varlistentry>
      <term>Sending in Email</term>
      <listitem><para>The resources can be sent in email to your friends, partners or to whomever you want. You will see the <guilabel>Send in Email</guilabel> menu entries in various places, like <menuchoice><guimenu>DTD</guimenu><guimenuitem>Send DTD Package (DTEP) in Email</guimenuitem></menuchoice>, <menuchoice><guimenu>Toolbars</guimenu><guimenuitem>Send Toolbar in Email</guimenuitem></menuchoice>, in the context menu of the files and folders in the <guilabel>Templates</guilabel> and <guilabel>Scripts</guilabel> tree.

    <varlistentry>
      <term>Uploading to the main server</term>
      <listitem><para>The resources can be uploaded to our main repository, from where all other &quantaplus; users can download them. The submissions are reviewed and made available only if our team considers correct and useful will be published. In order to make a valid submission it is suggested to sign the resources, thus you need a GPG/PGP key. This information is used to verify the origin of the resources both by our team and by the downloaders.</para>
        <para>About getting the resources from the main server see <xref linkend="download-resources" />.</para>
      <para>When uploading you will be asked to enter the passphrase for your secret GPG key (the passphrase will not be stored), or in the case of having more secret keys, you will be able to pick up the one you want to use. In the <guilabel>Share Hot New Stuff</guilabel> dialog fill the input fields (the <guilabel>Preview URL</guilabel> may remain empty) and start the upload by clicking <guilabel>OK</guilabel>.</para>
      <para>  
        The upload can be initiated from 
        <menuchoice><guimenu>DTD</guimenu><guimenuitem>Upload DTD Package (DTEP)</guimenuitem></menuchoice>, <menuchoice><guimenu>Toolbars</guimenu><guimenuitem>Upload Toolbar</guimenuitem></menuchoice>, in the context menu of the files and folders in the <guilabel>Templates</guilabel> and <guilabel>Scripts</guilabel> tree.

<sect1 id="download-resources">
<title>Getting Resources</title>
<para>It is possible to upgrade your &quantaplus; without getting a new version, by getting new resources like DTEP packages, toolbars with actions, templates, scripts and documentation. One possibility is that you got the resources in email or have downloaded from a web server, in which cases you usually need to manually install them. In lucky case you also got an install script when you have downloaded the resources. But &quantaplus; has a dedicated server holding resources that were either not included in the main distribution because of their sizes or infrequent usage, or they were contributed later by users, and these resources are automatically installed. Do download such resources use the various <guilabel>Download</guilabel> menu entries. You can find them at <menuchoice><guimenu>DTD</guimenu><guimenuitem>Download DTD Package (DTEP)</guimenuitem></menuchoice>, <menuchoice><guimenu>Toolbars</guimenu><guimenuitem>Download Toolbar</guimenuitem></menuchoice>, in the context menu of an empty area or toplevel item in the <guilabel>Templates</guilabel>, <guilabel>Scripts</guilabel> and <guilabel>Documentation</guilabel> trees. 
</para>
<para>
After a resource was downloaded, but before it is installed, &quantaplus; verifies if the resource is valid, by checking the integrity and the signature. In case of problems it warns you and you can decide if you want to continue or not. Please read the warning dialogs carefully. In the case when the integrity is correct and the resource is correctly signed, you will still get an information dialog, so you can see who created the resource.
</para>

<sect1 id="converting-dtd">
  <title>Converting a DTD to a &DTEP;</title>
  <para>It is possible to work on XML languages currently not supported by &quantaplus; by creating a DTEP package. But the creation can be time consuming, as you may need to write hundreds of tag files in <link linkend="tagxml-3-2">tagXML</link> format. Of course, there is a nicer way to go, by converting the DTD automatically into a DTEP package. 
  </para>
  <para>The conversion can be started from the <menuchoice><guimenu>DTD</guimenu><guimenuitem>Load &amp; Convert DTD</guimenuitem></menuchoice> menu. Select the <filename>.dtd</filename> file which defines the DTD you want to use, and after that you will see the following dialog:
    <mediaobject>
      <imageobject>
        <imagedata fileref="dtd-conversion.png" format="PNG" />
      </imageobject>
    </mediaobject>  
  </para>
<para>The entries are:</para>
<itemizedlist>
  <listitem><para><guilabel>Target directory name:</guilabel>the newly created &DTEP; will go under this name to the <filename><envar>$TDEHOME</envar>/share/apps/quanta/dtep</filename> folder.

  <listitem><para><guilabel>DTD URL:</guilabel> the URL pointing to the DTD file</para></listitem>

  <listitem><para><guilabel>Case-sensitive tags and attributes:</guilabel> self explaining, usually true for XML language variants</para></listitem>
  <listitem><para><guilabel>Fine-tune the DTEP after conversion:</guilabel> if checked, after the conversion is done, &quantaplus; will bring up the &descriptionrc; editor, so you can fine tune the newly created &DTEP;. It is recommended to leave this options checked.</para></listitem>
