3# Run a single lint from this dylint library against the Zed workspace.
4#
5# Usage:   tooling/lints/single-lint <lint_name> [cargo check args...]
6# Example: tooling/lints/single-lint blocking_io_on_foreground -p project_panel
7#
8# Dylint loads the whole library, so we silence every lint with `-A warnings`
9# and force just the requested one back on with `--force-warn`. A plain
10# `-W <lint>` is dropped for a driver-registered lint once the group is allowed,
11# which is why `--force-warn` is required.
12#
13# `DYLINT_RUSTFLAGS` is not part of Cargo's fingerprint, so changing it does not
14# invalidate already-checked crates. We therefore clean the targeted package(s)
15# first so the filter actually applies instead of replaying a stale cache. When
16# no package is named (a `--workspace` run) we drop the whole check cache.
