I'm working on GDB/MI compatible interface for Mago debugger on Windows.

GDB/MI is line based machine interface for debugger. IDEs are using GDB
via this interface.

GDB/MI docs: https://sourceware.org/gdb/onlinedocs/gdb/GDB_002fMI.html

Project page (mago fork) https://github.com/buggins/mago

Currently mago-mi supports subset of GDB commands enough for current
DlangIDE functionality.

Tested on DMD generated 32bit executables.

See readme details list of implemented commands:

Difference from baseline https://github.com/rainers/mago files are minimal:
- Static linking for MagoNatDE and MagoNatEE
- Disabled some Mago debug logging

Building mago-mi from source is easy. I've tried MS Visual Studio 2013
and 2015. Don't forget to edit properties in mago/PropSheets. Buld
mago-mi project.

Since DlangIDE v0.6.1, it includes prebuilt mago-mi.exe (it will be
copied into bin directory by dub build) and default Debugger settings
are changed from gdb to mago-mi by default on Windows. If you already
used DlangIDE on your computer, check Edit/Preferences/Debugger setting
- change to "mago-mi" if "gdb" is specified.

If you want to try mago-mi and DlangIDE which is using it, you can
download binaries from
(or just sync to latest dlangide and use `dub run`). Bundle includes
DlangIDE, mago-mi, dub, and sample workspaces (helloworld and tetris).
Download size is 5.4Mb (seems small enough for IDE+debugger).

I hope my work will be useful for other IDE developers who is targeting
on Windows.
(Any IDE which uses gdb/mi interface)
I tried gdb and lldb-mi before, but did not managed to find working
compiler + debugger configuration. (Best combination was gdb + gdc, but
it was showing global variables instead of locals. For lldb-mi, I
haven't managed to find compiler which produces compatible debug info).

Best regards,

Interesting. I was about to ask what was the main advantage over GDB? I reckon it is that Mago can debug executables with the COFF and/or OMF formats, right? (as opposed to GDB's DWARF format)
