Feature: Improved no-probe diagnostics #80

dragonmux commented 2026年04月04日 13:36:20 +02:00

In this PR we improve the diagnostics presented to the user when there is no probe found connected to the system, turning the "crash" output into a nice error print and exit.

For example:

❯ target/debug/bmputil-cli probe info
Error: ------------[ ✂ cut here ✂ ]------------
Unhandled crash in bmputil-cli v1.0.0
 0: Black Magic Probe device not found (check connection?)
Location:
 src/bin/bmputil-cli.rs:592
Backtrace omitted. Run with RUST_BACKTRACE=1 environment variable to display it.
Run with RUST_BACKTRACE=full to include source snippets.
Please include all lines down to this one from the cut here
 marker, and report this issue to our issue tracker at
https://codeberg.org/blackmagic-debug/bmputil/issues

becomes

❯ target/debug/bmputil-cli probe info
[2026年04月04日T11:34:39Z ERROR bmputil::bmp_matcher] Black Magic Probe device not found (check connection?)

This is done for all of the paths which use BmpMatcher and thus BmpMatchResults.
