Putting a `message' call in `vc-bzr-diff' yields this: files: (~/vc/emacs-bzr/trunk/) buffer: *vc-diff* rev1: 112671 rev2: 112672 > Dmitry, you will have to dig deeper.

I'm not sure how to find out. `vc-do-command' receives the following arguments: buffer: *vc-diff* command: bzr file-or-list: nil flags: (diff --diff-options -u -r 112671..112672) By the way, here's a (somewhat related) command that fails when invoked from command line: bzr diff --diff-options -U0 (`bzr diff' works fine.) Does Bazaar require additional programs to be installed?

"bzr diff" works as if -u was specified anyway, and will use its internal emulation of Diff if you don't pass --diff-options. > By the way, here's a (somewhat related) command that fails when invoked > from command line: > > bzr diff --diff-options -U0 > > (`bzr diff' works fine.) > > Does Bazaar require additional programs to be installed?

So restore your diff.exe, and things will work again. They do for me, because my diff.exe is in perfect working order. ^ permalink raw reply [flat|nested] 11+ messages in thread

I've rummaged around the manual a bit, and still don't understand what the recommended workflow is. Should I normally do `edebug-defun' before adding a breakpoint? How do I display the value of a local variable? Even after breakpoint hits, using `edebug-eval-expression' with the variable name still gives me "variable is void". How do I un-instrument a function? AFAICS, there are no commands like `edebug-cancel-', `-reset-' or `-remove-'. Please point me at any relevant documentation. >> `vc-do-command' receives the following arguments: >> >> buffer: *vc-diff* command: bzr file-or-list: nil flags: (diff >> --diff-options -u -r 112671..112672) > > Why do you use --diff-options? "bzr diff" works as if -u was > specified anyway, and will use its internal emulation of Diff if you > don't pass --diff-options. `vc-bzr-diff' does that automatically because `diff-switches' is '-u' here. If I remove that explicit setting from my config, it falls back to "-c", and that (when external diff program is present, of course) makes vc-bzr produce context diffs. Curiously, vc-git still uses the unified format in that case. Setting it to nil works as you expected. >> After recent overhaul of my MinGW installation, a number of Unix >> utilities became unavailable globally, including `diff'. > > That's probably related.

Sorry for the false alarm, I should have investigated it more myself first.

Oh. Though I believe it's called something like `Fcall_process' there. >> How do I display the value of a local variable? > > C-x C-e with point after it, I guess.

It's kind of an obvious solution, but I could've spent quite a while looking for a specialized command. ^ permalink raw reply [flat|nested] 11+ messages in thread
