The action reuses an active installation when its version matches the requested exact version. This avoids repeated downloads on persistent runners. Fixes #145.
The action checks the payload version, dependency files, directory selection, and shims before reuse. Node.js and package-manager management must match the installer's enabled defaults. The action then applies requested management opt-outs and continues the remaining setup steps. It adds the selected bin directory to
PATH.Reuse requires
VP_DUMP_DIRS, which releases from0.3.0support. Missing files, configuration changes, other active versions, dist-tags, ranges, and preview builds use the existing installer path.The regression test runs setup twice on Linux, macOS, and Windows with
VP_HOMEand split directories. A Linux case also checks XDG paths. The tests check for repeated downloads and changes toinstall.log.Local checks pass: 613 tests, type checking,
vp run check:fix,vp run build, and regression workflow validation. Two Windows-only tests are skipped locally. GitHub Actions checks are pending for the current commit.
