The discussion in #309 says that Mach won't use magical public declarations to set things such as options, however I think it makes sense to use them for (any applicable)...

### Zig Version 0.10.0-dev.3986+e323cf126 ### Steps to Reproduce Here is a repro case: ```zig const std = @import("std"); fn StructArray(comptime T: type) type { // std.debug.assert(@alignOf(T) == 8); const field...

Custom test runner

This PR adds the ability to specify a custom test runner via a new `--test-runner` CLI option, or the `std.build.Builder.test_runner_path` field. There are a few aspects I'm uncertain about: -...

Closes #14822. This PR implements the simple solution I mentioned in the linked issue by using a hashmap to detect when an attempt is made to add a top-level step...

std.io.tty: add detectTtyConfigForce for forcing color

Having some common machine-readable format(s) would be helpful for analyzing results. There should be a format that is easy for plotting packages like gnuplot and matplotlib to consume - I...

add an option to show ratio instead of percent delta (possibly by default)

2

I think that percentages are not easier to comprehend than ratios, especially when the delta is quite big. An example: Benchmark 1 (376 runs): zig-out/bench/ReleaseSafe/zimalloc/create-destroy-loop-native-ReleaseSafe: measurement mean ± σ min...
