Change output format on host

[timhoeppner]

I'm not really sure if this is considered an issue but I can't seem to find a way to configure the format shown on the host. Its currently shown like:

0 Hello, world!
└─ minimal::app::init @ src\bin\minimal.rs:32
1 in foo
└─ minimal::app::foo @ src\bin\minimal.rs:77
2 in bar
└─ minimal::app::bar @ src\bin\minimal.rs:86
3 in foo
└─ minimal::app::foo @ src\bin\minimal.rs:77

I might like to do something like:

minimal::app::init[src\bin\minimal.rs:32]: 0 Hello, world!
minimal::app::foo[src\bin\minimal.rs:77]: 1 in foo
minimal::app::bar[src\bin\minimal.rs:86]: 2 in bar
minimal::app::foo[src\bin\minimal.rs:77]: 3 in foo

or any other permutation.

Is this possible?

defmt does not define the output format but if you are using probe-run you can use the new-ish --json flag (it's there in v0.3.3) and then pipe that into some formatter program that produces the desired format, i.e. probe-run --chip some-chip --json my-elf | my-formatter. you can use defmt-json-schema to decode probe-run's output. there's example output and an example formatter in https://github.com/knurling-rs/defmt/tree/a10d971661d723e8e58e24f4be51ce5f1767d6df/decoder/defmt-json-schema/examples

This is great, thanks!

I'm putting together a little tool to process the json stream from probe-run if anyone is interested. Eventually plan to have a custom definable format but just slapped this together to satisfy my immediate need.

Nice! Someone is actually using the json output. I am happy 😁
