+ * FUTURE CHANGES:
+ *
+ * The timestamp functionality has intentionally been
+ * split in two parts for future use even though it
+ * is not used like this today. take_timestamp() takes
+ * the timestamp and calculate heap need for it (which
+ * is not constant). write_timestamp() writes the
+ * timestamp to the allocated heap. That is, one typically
+ * want to take the timestamp before allocating the heap
+ * and then write it to the heap.
+ *
+ * The trace output functionality now use patch_ts_size(),
+ * write_ts(), and patch_ts(). write_ts() both takes the
+ * timestamp and writes it. Since we don't know the
+ * heap need when allocating the heap area we need to
+ * over allocate (maximum size from patch_ts_size()) and
+ * then potentially (often) shrink the heap area after the
+ * timestamp has been written. The only reason it is
+ * currently done this way is because we do not want to
+ * make major changes of the trace behavior in a patch.
+ * This is planned to be changed in next major release.

- <title>Introduction</title>
+ <title>Getting Started</title>
- <p><em>Debugger</em> is a graphical user interface for the Erlang
- interpreter, which can be used for debugging and testing of
- Erlang programs. For example, breakpoints can be set, code can be
- single stepped and variable values can be displayed and changed.
- </p>
+ <p>To use Debugger, the basic steps are as follows:</p>
- <p>The Erlang interpreter can also be accessed via the interface
- module <c>int</c>, see <seealso marker="int">int(3)</seealso>.
- </p>
+ <p><em>Step 1.</em> Start Debugger by calling
+ <c>debugger:start()</c>.</p>
- <p><em>Warning:</em> Note that the Debugger at some point might
- start tracing on the processes which execute the interpreted
- code. This means that a conflict will occur if tracing by other
- means is started on any of these processes.</p>
- </section>
+ <p>The <seealso marker="#monitor">Monitor window</seealso> is
+ displayed with information about all debugged processes,
+ interpreted modules, and selected options. Initially there are
+ normally no debugged processes. First, it must be specified which
+ modules that are to be <em>debugged</em> (also called
+ <em>interpreted</em>). Proceed as follows:</p>
- <section>
- <title>Getting Started with Debugger</title>
+ <p><em>Step 2.</em> Select <em>Module > Interpret...</em> in the
+ Monitor window.</p>
- <p>Start Debugger by calling <c>debugger:start()</c>. It will start
- the <seealso marker="#monitor">Monitor window</seealso> showing
- information about all debugged processes, interpreted modules and
- selected options.</p>
+ <p>The <seealso marker="#interpret">Interpret Modules window</seealso>
+ is displayed.</p>
- <p>Initially there are normally no debugged processes. First, it
- must be specified which modules should be <em>debugged</em>, or
- <em>interpreted</em> as it is also called. This is done by
- choosing <em>Module->Interpret...</em> in the Monitor window and
- then selecting the appropriate modules from the
- <seealso marker="#interpret">Interpret Dialog window</seealso>.
- </p>
+ <p><em>Step 3.</em> Select the appropriate modules from the Interpret
+ Dialog window.</p>
<note>
- <p>Only modules compiled with the option <c>debug_info</c> set
- can be interpreted. Non-interpretable modules are shown within
- parenthesis in the Interpret Dialog window.</p>
+ <p>Only modules compiled with option <c>debug_info</c> set can be
+ interpreted. Non-interpretable modules are displayed within
+ parenthesis in the Interpret Modules window.</p>
</note>
- <p>When a module is interpreted, it can be viewed in a
- <seealso marker="#view">View Module window</seealso>. This is done
- by selecting the module from the <em>Module->module->View</em>
- menu. The contents of the source file is shown and it is possible
- to set <seealso marker="#breakpoints">breakpoints</seealso>.</p>
-
- <p>Now the program that should be debugged can be started. This is
- done the normal way from the Erlang shell. All processes executing
- code in interpreted modules will be displayed in the Monitor
- window. It is possible to <em>attach</em> to one of these
- processes, by double-clicking it, or by selecting the process and
- then choosing <em>Process->Attach</em>.</p>
-
- <p>Attaching to a process will result in a
- <seealso marker="#attach">Attach Process window</seealso> being
- opened for this process. From the Attach Process window, it is
- possible to control the process execution, inspect variable
- values, set breakpoints etc.</p>
+ <p><em>Step 4.</em> In the Monitor window, select
+ <em>Module > the module to be interpreted > View</em>.</p>
+
+ <p>The contents of the source file is displayed in the
+ <seealso marker="#view">View Module window</seealso>.</p>
+
+ <p><em>Step 5.</em> Set the
+ <seealso marker="#breakpoints">breakpoints</seealso>, if any.</p>
+
+ <p><em>Step 6.</em> Start the program to be debugged. This is done
+ the normal way from the Erlang shell.</p>
+
+ <p>All processes executing code in interpreted modules are displayed
+ in the Monitor window.</p>
+
+ <p><em>Step 7.</em> To <em>attach</em> to one of these processes,
+ double-click it, or select the process and then choose
+ <em>Process > Attach</em>. Attaching to a process opens an
+ <seealso marker="#attach">Attach Process window</seealso> for this
+ process.</p>
+
+ <p><em>Step 8.</em> From the Attach Process window, you can control
+ the process execution, inspect variable values, set breakpoints,
+ and so on.</p>

<title>Getting Started</title>
- <p>The <c>ttb</c> module is the interface to all functions in the
- Trace Tool Builder. To get started the least you need to do is to
- start a tracer with <c>ttb:tracer/0/1/2</c>, and set the required
- trace flags on the processes you want to trace with
- <c>ttb:p/2</c>. Then, when the tracing is completed, you must stop
- the tracer with <c>ttb:stop/0/1</c> and format the trace log with
- <c>ttb:format/1/2</c> (as long as there is anything to format, of
- course).
