Jonah Graham f0c2358276 Migrate New and Noteworthy from Wiki to GitHub 
This commit migrates all the N&N content from
https://wiki.eclipse.org/CDT/User/NewInCDT to GitHub.

For newer releases (>= CDT 10.0) the entire content has
been rewritten in GitHub flavour Markdown. For older
releases, the N&N page has simply been saved in a
rendered format.

<h2><span class="mw-headline" id="Editor">Editor</span></h2>
<h3><span class="mw-headline" id="Override_Markers">Override Markers</span></h3>
<p>In C++ files, method declarations and definitions are annotated on the vertical bar using three types of symbols:
</p>
<ul><li>Override (<i>green triangle</i>) indicating that a virtual method in one of base classes is overridden, </li>
<li>Implement (<i>empty blue triangle</i>) indicating that a pure virtual (abstract) method in one of base classes is overridden, </li>
<li>Shadow (<i>dark blue triangle</i>) indicating that a method in one of base classes <i>with the same paremeter set</i> is shadowed.</li></ul>
<p><a href="https://wiki.eclipse.org/File:CDTOverrideMarkers.png" class="image"><img alt="CDTOverrideMarkers.png" src="./CDT-8.0_files/CDTOverrideMarkers.png" width="293" height="154"></a>
</p><p>As in JDT, the annotations have the action which allows to go to the declaration in base.
</p><p>In case of multiple inheritance, the messages also contain the name of <i>direct</i> base class of the overriding method's class if the overrided method's class is further up the inheritance hierarchy.
</p><p>Contrary to JDT, several messages are sometimes generated on one marker (e.g. when the same method is overridden through several base classes).
</p>
<h3><span class="mw-headline" id="Selection_Expansion">Selection Expansion</span></h3>
<p>The C++ editor now allows to expand the selection to enclosing, next and previous nodes of the AST, as well as restore the hierarchy.
</p><p><a href="https://wiki.eclipse.org/File:CDTExpandSelection.png" class="image"><img alt="CDTExpandSelection.png" src="./CDT-8.0_files/CDTExpandSelection.png" width="772" height="236"></a>
</p><p>The behaviour is strictly analogous to JDT and the actions are located in "Edit -&gt; Expand Selection To" menu.
</p>
<h3><span class="mw-headline" id="Camel_Case_Completion">Camel Case Completion</span></h3>
<p>The C/C++ now supports camel case completion similar to the one of the JDT. The following additional features are available:
</p>
<ul><li>underscore notation (I): <code>FB</code> matches <code>FooBar</code> as well as <code>FOO_BAR</code> or <code>Foo_Bar</code> </li>
<li>underscore notation (II): you can also type the underscore in the text, in which case matches are explicitly required to contain the underscore. <code>F_B</code> matches <code>FOO_BAR</code>, but not <code>FooBar</code>. </li>
<li>you don't need to specify all segments: It is OK to omit segments (not the first, however): <code>OTh</code> matches <code>OneTwoThree</code>, even though no characters for <code>Two</code> are specified. </li>
<li>a segment in the matching name can consist of only upper case letters: <code>IOT</code> matches <code>IONETWO</code>.</li></ul>

</p>
<h3><span class="mw-headline" id="Configurable_Name_Style">Configurable Name Style</span></h3>
<p>User-configurable name styles for constants, variables, class fields, getters and setters, and for header, source and test files.

</p>
<h3><span class="mw-headline" id="New_Code_Formatting_Options">New Code Formatting Options</span></h3>
<p>New options for formatting of constructor initializer lists, stream output expressions, and inline comments. Numerous improvements to the code formatter.

</p>
<h3><span class="mw-headline" id="New_Code_Templates">New Code Templates</span></h3>
<p>New code templates for namespace and class declarations and for C++ test files.
</p><p><a href="https://wiki.eclipse.org/File:CodeTemplates.png" class="image"><img alt="CodeTemplates.png" src="./CDT-8.0_files/CodeTemplates.png" width="637" height="671"></a>

<h3><span class="mw-headline" id="Error_Markers_for_Unresolved_Symbols">Error Markers for Unresolved Symbols</span></h3>
<p>Codan now has a checker which generates Problems on instances of ProblemBindings in AST, generated by the Parser. This allows to reveal many errors while typing.
</p><p><a href="https://wiki.eclipse.org/File:SemanticProblems.png" class="image"><img alt="SemanticProblems.png" src="./CDT-8.0_files/SemanticProblems.png" width="396" height="404"></a>
</p><p><br>
Quick fixes are provided for a subset of problems. As for now, the available fixes are:
</p>
<ul><li>Name resolution problem:
<ul><li>Create Local Variable </li>
<li>Create Field </li>
<li>Create Parameter</li></ul></li></ul>

</p><p><br> <b>Configuring GDB for pretty-printing:</b>
</p>
<ul><li>You will need to have python installed on your machine</li></ul>
<ul><li>If you want to pretty-print STL structures, you will need the Python pretty-printers for STL. Check-out the latest Python libstdc++ printers to a place on your machine. (Note that you can create your own pretty-printers for any complex-structure). In a local directory, do:</li></ul>
<pre> svn co <a rel="nofollow" class="external free" href="svn://gcc.gnu.org/svn/gcc/trunk/libstdc++-v3/python">svn://gcc.gnu.org/svn/gcc/trunk/libstdc++-v3/python</a>
</pre>
<ul><li>You will need to create a gdbinit file to tell GDB where the pretty-printers are. Create a gdbinit file with the following 6 lines. The path needs to match where the python module above was checked-out. So if checked out to: /home/marc/gdb_printers/, the path would be as written in the example:</li></ul>
<pre> python
import sys
sys.path.insert(0, '/home/marc/gdb_printers/python')
from libstdcxx.v6.printers import register_libstdcxx_printers
register_libstdcxx_printers (None)
end
</pre>
<ul><li>You will need GDB 7.0 or later. GDB 7.2 is recommended because it has some bug fixes for the pretty-printing.</li></ul>
<ul><li>In your DSF-GDB launch, make sure you use the right GDB and the right gdbinit file</li></ul>
<h3><span class="mw-headline" id="Support_for_pending_breakpoints">Support for pending breakpoints</span></h3>
<p>When a breakpoint is set in a dynamically-linked library that was not loaded yet, the breakpoint will now work, once the library is loaded. See <a rel="nofollow" class="external text" href="http://bugs.eclipse.org/248595">bug 248595</a>. This feature is currently only supported when using GDB 6.8 or later.
</p>
<h3><span class="mw-headline" id="Showing_cores_in_Debug_view_labels">Showing cores in Debug view labels</span></h3>
<p>By using the enhancements of GDB 7.1, DSF-GDB now shows the core on which each thread runs as an extra part of the Debug View label. The list of all cores on which a process is located is also added as a label. The below image shows the new feature.
</p><p><a href="https://wiki.eclipse.org/File:CoreLabels.png" class="image"><img alt="CoreLabels.png" src="./CDT-8.0_files/CoreLabels.png" width="696" height="295"></a>

<h3><span class="mw-headline" id="Showing_cores_and_owner_in_attach_prompter">Showing cores and owner in attach prompter</span></h3>
<p>DSF-GDB now shows the owner of a process as an extra part of the process prompt for an attach session. The owner id will be shown starting with GDB 7.0. For a Remote attach session (using gdbserver --multi), the cores on which a process is located will also be shown. Showing the cores starts with GDB 7.1. The below image shows the new feature.

<h3><span class="mw-headline" id="Multi-process_Debugging">Multi-process Debugging</span></h3>
<p>CDT now supports debugging multiple processes in a single debug session. It allows to attach/detach and start/stop processes repeatedly and easily.
</p><p>Requirements:
</p>
<ul><li>GDB 7.2 or greater </li>
<li>Currently, only Non-Stop debugging sessions support multiple processes. </li>
<li>Note that this feature was developed and tested on Linux systems, and may not work on Windows.</li></ul>
<p>To use multi-process debugging, simply launch an application as you normally would, locally or remotely, using gdbserver, and make sure to select Non-stop mode in the Debugger tab. Then, use the Debug View's "Connect" button to trigger a dialog with allows you to either attach to a running process, or to create a new process using the "New..." button. Currently, the "New..." button is only supported for Local debug sessions.
</p><p><a href="https://wiki.eclipse.org/File:MultiAttachDialog.png" class="image"><img alt="MultiAttachDialog.png" src="./CDT-8.0_files/MultiAttachDialog.png" width="600" height="459"></a>
</p><p><br>
</p><p>You will then have the newly selected process added to your debug session, where you can control it and examine it. You can use the "Disconnect" button to remove processes from your debug session, or you can use the "Connect" button to add new ones.
</p><p><a href="https://wiki.eclipse.org/File:MultiProducerConsumer.png" class="image"><img alt="MultiProducerConsumer.png" src="./CDT-8.0_files/MultiProducerConsumer.png" width="500" height="412"></a>
</p><p><br>
</p><p>An option to automatically attach to a forked process is also available. This means that whenever any process you are currently debugging forks a new process, that new process will be added to your debug session.
</p><p><br> <a href="https://wiki.eclipse.org/File:AutoAttachOption.png" class="image"><img alt="AutoAttachOption.png" src="./CDT-8.0_files/AutoAttachOption.png" width="700" height="511"></a>
</p>
<h3><span class="mw-headline" id="C.2FC.2B.2B_Remote_Application_launch">C/C++ Remote Application launch</span></h3>
<p>The optional "C/C++ Remote Application" launch configuration type has been made permanent for CDT.
</p><p><a href="https://wiki.eclipse.org/File:Debugconfig.jpg" class="image"><img alt="Debugconfig.jpg" src="./CDT-8.0_files/Debugconfig.jpg" width="477" height="337"></a>
</p><p>The "GDB (DSF) Remote System Process" launch delegate has been renamed to "GDB (DSF) Manual Remote Debugging" and has been moved from "C/C++ Application" to "C/C++ Remote Application". As was the case for CDT 7.0, the optional RSE Remote Launch delegate of org.eclipse.cdt.launch.remote, is still part of "C/C++ Remote Application".
</p><p>This optional remote launch now provides a new DSF-GDB-based launch delegate called "GDB (DSF) Automatic Remote Debugging". This launch is very similar to the existing "GDB (DSF) Manual Remote Debugging" delegate, except that the automatic one will automatically download the application to the remote target and start gdbserver with the application.
</p><p><a href="https://wiki.eclipse.org/File:RemoteDelegates.jpg" class="image"><img alt="RemoteDelegates.jpg" src="./CDT-8.0_files/RemoteDelegates.jpg" width="432" height="502"></a>
</p><p>By default, the user will be shown the "GDB (DSF) Manual Remote Debugging". However, if the optional feature of Remote Launch is installed, the default will automatically become the more feature-rich "GDB (DSF) Automatic Remote Debugging".
</p><p>Finally, the run-mode RSE Remote Launch delegate no longer shows the Debugger or Source tabs, since they were not relevant, in run-mode.
</p>
<h3><span class="mw-headline" id="New_set_of_preferences">New set of preferences</span></h3>
<p>A set of new preferences have been added to <i>Preferences-&gt;C/C++-&gt;Debug-&gt;GDB</i> to allow users to have a better debugging experience.
</p><p><b>Note:</b> after a new workspace is created, this debug preferences page will only be visible once the first debug session is started.
</p><p>These new preference are:
</p>
<ul><li>Default GDB path and initialization file: default path for the location of GDB as well as for the GDB initialization file. </li>
<li>Default behavior for <i>Stop on startup</i>: default behavior to stop the execution on startup, and on what symbol. </li>
<li>Default Non-stop mode: default behavior to automatically enable non-stop mode or not. Non-stop mode allows to control the execution of threads and processes independently. </li>
<li>Default limit for GDB Traces: limits the amount of traces printed on the <i>gdb traces</i> console </li>
<li>Default enabling of pretty-printing: assuming a pretty-printing enabled GDB, automatically enabled pretty-printing in CDT </li>
<li>Default child limit for pretty-printing: default to control the amount of children automatically shown by a pretty-printer</li></ul>
