Debuggers

To debug D programs you need to use a debugger that understands the format of the debug symbols information that your chosen compiler produces. The quality of the debug symbols information might vary depending on which compiler you use and its underlying debug format. For example, some compiler configurations may present the names of variables and/or functions in it's C mangled form, instead of the natural D name.

Debugging support by compiler

Compiler+Platform	Format	Debugger	Supported functionality
DMD-Win32	OMF	Mago/VisualD	Good support: Breakpoints; Stack frames; Mostly pretty names ('.' shows up as '@'); Variable inspection; Visual Studio based.
		WinDbg	Supplied with the main D compiler zip file download. Overview
		ddbg	Doesn't seem to be working well. Project no longer maintained.
DMD-Win64	COFF	Mago/VisualD	TODO: same level of support as for win32?
DMD-Linux GDC-Linux LDC-Linux GDC-Win32/64	DWARF	GDB	Good support: Breakpoints; Stack frames; Pretty names; Variable inspection;
		ZeroBUGS	"Modular debugger for C/C++/D programming languages (and virtually anything else that supports Stabs/DWARF debug formats)". Supported debugging functionality??
LDC-MinGW	DWARF	-	DWARF debug symbol info seems to be broken for LLVM compiled with MinGW note
DMD-MacOS GDC-MacOS LDC-MacOS	?	GDB	Limited/outdated support? According to Jacob Carlberg: "D symbols need to be prefixed with an extra underscore." "Line numbers don't work."
		LLDB	?

Graphical debugger frontends

Frontends providing support to a command-line debugger mentioned in the previous section.

Debugger	Frontend	Description	Platform
GDB	Mono-D	MonoDeveloped-based full D IDE. Has integration with the GDB debugger. "Debugging (using MonoDevelop’s integrated gdb support on Linux currently)"	Linux?
GDB	DDT	Eclipse-based IDE. Has integration with the GDB debugger, including D support. (Debugging support is based on Eclipse CDT)	Linux, Windows, MacOS
GDB	Nemiver	Graphical frontend to the GDB debugger, which supports full D syntax from version 7.2.	Linux
GDB	CGDB	Command line frontend to the GDB debugger, which supports full D syntax from version 7.2.Shows code and the GDB console in split windows.	Linux, MacOS
GDB	DDD	GNU DDD is a graphical front-end for command-line debuggers such as GDB. Usual front-end features such as viewing source code, viewing variables, etc.	Linux
GDB	Affinic Debugger	Affinic Debugger GUI .aka. ADG, is designed as a graphical user interface for various debuggers. This version is specifically targeted on GDB, the GNU debugger.	Linux, Windows, MacOS
