<h1>Embedding Commands as Links</h1>
by Chris Daly (cjdaly@us.ibm.com)<br>
version 0.1 (15-Jan-2006)<br>
<br>
<br>
This document is meant to serve as a guide to authors of Help,
Cheatsheets, Intro and possibly other document types who would benefit
from the ability to embed commands in their documents as links.&nbsp;
The centerpiece of this document is a catalog of commands that are
thought to be useful in embedded document contexts.<br>
<br>
<h2>Background</h2>
A <a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=120523">recent
enhancement</a> to the command framework allows commands and their
parameter values to be serialized as strings and later deserialized and
executed.&nbsp; This allows serialized commands to be embedded in
documents and visualized as links such that activating the link has the
effect of&nbsp; executing the embedded command.<br>
<br>
<a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=121709">Another
enhancement</a> introduces the notion of typed command
parameters.&nbsp; Previously, parameter values were expressed as
strings throughout the lifecycle of command parameterization and
execution.&nbsp; Now command parameters can declare a type and the
parameter values can be handled as objects instead of strings.&nbsp;
This allows:<br>
<ul>
  <li>object parameter values to be handled correctly by the
serialization/deserialization mechanism described above</li>
  <li>multiple handlers of a command to convert string to object
parameter values in a consistent way</li>
  <li>tooling to search for commands that operate on certain types of
objects</li>
</ul>
This work was done with the goal of allowing commands to be embedded as
links in the various types of User Assistance documents: Help,
Cheatsheets and Intro.&nbsp; The functionality may also be useful in
other contexts.<br>
<br>
Two additional things are required for the ability to embed commands in
documents to become a useful and used feature.&nbsp; First, we must
have a reasonably large "catalog" of commands that do
interesting/useful things when embedded in documents.&nbsp; Second,
each type of document must specify how commands may be embedded and its
supporting code must present the commands in some way that allows them
to be invoked by users (such as a clickable link).&nbsp; These topics
are explored in detail below.<br>
<br>
<h2>An Example<br>
</h2>
Below is an HTML document that represents a Help topic.&nbsp; The
JavaScript <span style="font-family: monospace;">executeCommand</span>
function takes a serialized command as its argument and executes the
command when the link is clicked.&nbsp; <span
 style="font-style: italic;">Note that this requires the patch for <a
 href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=122726">bug 122726</a>,
which is not yet committed.</span><br>

<h2>Catalog of Commands</h2>
What follows is a catalog of commands that may be useful in embedded
document scenarios.&nbsp; Some of these are available today and some
are not yet committed (indicated with [proposed] below).&nbsp; The
