Hello,

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: https://github.com/buggins/mago/tree/master/MagoMI/mago-mi

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 https://sourceforge.net/projects/crengine/files/DlangUI/dlangide-v061-magomi-v010-x86.zip/download (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,
    Vadim
