Add `bencher schema` subcommand

[SignpostMarv]

requesting a bencher CLI command with which one can dump bmf.json

currently doing this:

FROM ghcr.io/bencherdev/bencher-console:v0.5.10 AS bencher

FROM alpine AS downloads
ADD https://github.com/bencherdev/bencher/releases/download/v0.5.10/bencher-v0.5.10-linux-x86-64 /bencher
COPY --from=bencher /usr/src/bencher/dist/client/bmf.json /bmf.json
COPY sha512sum.txt sha512sum.txt
RUN sha512sum -c sha512sum.txt

FROM mcr.microsoft.com/devcontainers/base:ubuntu

COPY --from=downloads --chown=vscode:vscode /bencher /home/vscode/.local/bin/bencher
COPY --from=downloads --chown=vscode:vscode /bmf.json /app/bencher/bmf.json
RUN chmod +x /home/vscode/.local/bin/bencher

would rather just be able to bencher [some sensible command here] > ./bmf.json

reasoning being is that https://bencher.dev/bmf.json isn't versioned, so if the format changes in future one cannot do version-specific tooling.

Hey @SignpostMarv good catch!

I'm open to a PR adding a bencher schema subcommand that just outputs the current BMF schema.
Or a PR adding a https://bencher.dev/v0/bmf.json route on the server.

Or both honestly sound like good ideas to me.

May have a look in the morning after I've put a bencher-friendly formatter in my benchmark.js fork (have one prototyped, but one should really be sleeping instead of continuing to tinker approaching 2am 😅)

Getting the bencher integration to deploy & behave took longer than expected, taking a dev break once my github action finishes & will look at this tomorrow.

Have took a look at the code, rust makes me 👀

Probably not the best option for me to be first diving into coding in rust, will have to opt out of contributing on this one 😅

@SignpostMarv I have added a versioned BMF schema here: https://bencher.dev/v0/bmf.json

that also works, although would leave this ticket open pending myself or someone else getting around to having the time to add bencher schema
