Six v0.3.0: coverage heatmaps in the HTML report
Six is a zero-dependency coverage tool that wraps :cover with smart defaults and a structured markdown report (.six/coverage.md) built for AI coding agents to read and act on.
v0.3.0 adds a heatmap to the HTML formatter. Run mix six.html –open and every source line is shaded by how many times your test suite actually ran it. Missing coverage and degrees of coverage, both obvious at a glance.
Six is mostly built for agents, but this release is for humans.
