Rust implementation: single static binary, argv[0]-dispatch shims#1
Merged
Conversation
Full port of the sh implementation to dependency-free Rust (std only; downloads still shell out to curl/tar). One binary is both the CLI and every shim — shims are symlinks to it, dispatched on argv[0], like Volta. Resolution is ~1.7ms vs ~12ms for the sh version. test/smoke.sh stays as the shared conformance suite (now driving the binary via JOLTA_BIN, with a machine-readable 'jolta jdks' command); all 19 checks pass including live Adoptium auto-install. install.sh builds from source until prebuilt binaries are published.

Pins and installs can name a distro: corretto@21 / graalvm-25 (also in .java-version). Downloadable: temurin (default), corretto, graalvm, oracle — plus zulu/openjdk recognized when matching installed JDKs via release IMPLEMENTOR and path. A distro-qualified pin only matches that distro and auto-installs it when missing. Terminal UI: colored, glyphed output across commands and an animated download progress bar (spinner, bar, percent, size, throughput) drawn by polling the file against the redirect chain's Content-Length; plain output when piped, NO_COLOR and TERM=dumb respected. Fixes the content-length probe (curl -w has no such variable; parse the header). Conformance suite grows to 21 checks: distro-aware resolution (corretto pin prefers corretto over same-major openjdk; wrong-distro pin fails offline) plus live corretto@21 and temurin@25 installs verified.

ui (terminal styling), paths, jdk (spec parsing + discovery), resolve (matching/cache/pin/auto-install), download (progress bar), install (vendor URLs + install), commands (CLI handlers), and a slim main.rs for dispatch and shim mode. Pure code movement; no behavior change.

Summary
Full port of jolta from POSIX sh to dependency-free Rust (std only — downloads still shell out to
curl/tar, keeping the supply chain empty).joltait's the CLI; invoked through a shim symlink (java,javac, …) it dispatches on argv[0], resolves the pinned JDK, setsJAVA_HOME, and execs the real tool — the Volta architecture, with zero script parsing on the hot path.java -versionis indistinguishable from barejava.corretto@21/graalvm-25in pins and installs; temurin (default), corretto, graalvm, oracle downloadable; zulu/openjdk recognized when matching installed JDKs.
