Re: [frogs] Help with the Guile debugger

["Trevor Daniels" <t.daniels@xxxxxxxxxxx>]

Hi Ian

Many thanks for this!  It looks good,  but I've not been able to
try it out in detail as the patch didn't apply:

> fatal: git-apply: bad git-diff - expected dev/null on line 260

and it was too tricky to extricate all the instructions from the
patch itself.

There were also a few lines with trailing white space.

I did notice the following:

Patch line 95: should be ddd

but otherwise the gdb instructions look fine.

Could you try to make a patch again, please, or alternatively
send me the complete .itexi file?

Trevor

Hi Trevor,
Firstly a Happy New Year/ Glückliches NeuJahr/ Bonne Nouvelle Année/ 
een
vrolijke nieuwe jaar/ un feliz año nuevo

to all on the Frogs List.

Attached is a patch with some changes to the guile debugger code and 
the
documentation (CG Chapter 8).

Please test-drive and review.

Cheers,

Ian
