Editor

Open Declaration on decltype

Open Declaration on a decltype token now opens the declaration of the deduced expression type (bug 520913).


Code Analysis

A new quick fix was added for suppressing a problem by adding a suppression comment (bug 495842).

Formatter

Command line code formatter It is now possible to format source code without starting the Eclipse UI using the new headless formatter application. The command line formatter works as a standard Eclipse application.


The following command will format the source files in the folder src with the options specified in the org.eclipse.cdt.core.prefs file:

eclipse -nosplash -application org.eclipse.cdt.core.CodeFormatter -consoleLog \
        -verbose -config .settings/org.eclipse.cdt.core.prefs src/

See Using the Formatter Application and bug 520340 for details.


Parser


Build


Headless Build Headless build has three new command line arguments:
  • -marker-type which specifies which marker types to consider when failing a build. Can be all (default) cdt (shortcut for C/C++ Problems) or any marker ID. Can be specified multiple times to check for multiple markers. Can be used to, for example, prevent C/C++ Scanner errors from causing build failures.
  • -printErrorMarkers prints all error markers (debugging option) at the end of a build. Can be used to diagnose why build has failed (specific error markers).
  • -help display help.

See (bug 520163).


Debug


External Console You can now debug a program with an external console window easily in CDT on Windows. This prevents GDB mixing its input/output with the program being debugged. CDT launches the new console by telling GDB with "set new-console on". This is a Windows only feature as only Windows has support for "set new-console on".

You can set whether to use an external console window in the launch configuration:

You can set the default value for any newly created launch configurations in the preferences:

API modifications


org.eclipse.cdt.debug.gdbjtag.ui
  1. The method GDBJtagStartupTab#createRunOptionGroup(Composite) has been deprecated because the content of the run options group and the run commands group has been merged within the Startup page of the UI (see bug 525692). Extenders should override GDBJtagStartupTab#createRunGroup(Composite) instead.

Bugs Fixed in this Release

Launch Bar


The CDT 9.4 release include the Launch Bar 2.2.0 minor release.

The main feature in this release is clean up of the New Launch Config wizard so that the launch mode and launch configuration types appear on the same page. This simplifies the UX by showing the user why selecting the Mode is important, i.e. it changes the list of available types that support that mode.

Additionally we've added a new way of specifying New Launch Target wizards so that the wizard can be also used to edit the target.

And finally, we've added a mechanism for adding Build Settings tabs to the Descriptor editor.
