I recently discovered Nemerle and F#, but I can't find any way to debug my applications. MonoDevelop 2.6 lacks support of Nemerle and F#, 2.4.2 and earlier crashes because of newer gnome-sharp lib is installed (I'm running up-to-date Arch Linux kernel-3.0 64-bit). Command-line mono debugger refuses to start saying "platform not supported". So few questions about this situation:
It is possible to debug mono applications using gdb without going on low-level (inside vm or so) ? How comfortable to use F# REPL for interactive development without debugger (compared to Common Lisp or Haskell's GHCi)?
I use the F# Interactive environment to write F# code most of the time. Even with Visual Studio, the F# Interactive environment doesn't (reasonably) support debugger, so I mainly rely on the ability to easily run something interactively and see if it works - if it doesn't, it is usually easy to split into sub-components that can be tried interactively too. The great thing about F# Interactive, compared to for example GHCi, is that you can use it to evaluate pretty much anything - including type declarations.
The F# plugin for MonoDevelop 2.4 doesn't currently support debugging of compiled F# applications. I was able to use command line Mono debugger (mdb, I think), but that was on 32bit system.
I'm not sure why MonoDevelop doesn't correctly pick F# debug symbols, so this is most likely some basic bug. There are a few poeple working on F# plugin for MD 2.6, so that should hopefully be available soon. If anybody wanted to investigate why the debugging doesn't work, that would be great...
