  • Split walkthrough into focused pages and add refset section (f17e1b4)

  • Remove old monolithic walkthrough.md (d03d362)

  • Update README (3d99cda)

Features

  • Add Simple refset support end-to-end (76e6f0f)

  • Configurable one-line concept listing format (95fe2d2)

  • Update installation instructions and add shell one-liners for easier setup (894bbaa)

Other

  • Add install.ps1 and auto-bump Homebrew tap + Scoop bucket on release

Tier 2 distribution wiring. Each release now fans out to package managers automatically, on top of the Tier 1 GitHub Releases + crates.io + curl|sh flow already in place.

install.ps1: Windows PowerShell installer, the counterpart to install.sh. Auto-detects architecture, looks up the latest release tag via the GitHub API, downloads sct-windows-x86_64.zip plus SHA256SUMS, verifies the checksum, extracts to $env:LOCALAPPDATA\sct\bin by default (overridable via $env:SCT_INSTALL_DIR), and offers to add the install directory to the user PATH.

One-liner install on Windows:

iwr -useb https://raw.githubusercontent.com/pacharanero/sct/main/install.ps1 | iex

release.yml: new update-taps job that runs after the GitHub release is published. It pulls the just-published SHA256SUMS, extracts each of the five per-target hashes, and rewrites:

  • Formula/sct.rb in pacharanero/homebrew-sct
  • bucket/sct.json in pacharanero/scoop-sct

then commits and pushes. Both target repos are cloned with a PAT stored as the TAP_REPOS_TOKEN secret — this must be a token with write access to both repos. Without the secret, the job will fail visibly but the main release (GitHub Release + crates.io) will still succeed, since update-taps has needs: release and is not itself a prerequisite for anything downstream.

The Scoop manifest also carries its own checkver / autoupdate block, so Scoop's own update machinery can pick up new versions without this workflow — the workflow just makes the update immediate rather than eventually-consistent.

Roadmap: marked the distribution checklist items complete and added a "Future distribution work" sub-list for the harder items (macOS notarization, Windows Authenticode signing, .deb/.rpm, winget, nixpkgs) that still need either money or patience.

[0.3.9] - 2026-04-10

Bug fixes

  • Update path to Cargo.toml and adjust git add command (c6f2cc0)

  • Update readme path in Cargo.toml (01efae6)

Other

  • Add Windows + Linux ARM builds, SHA-256 checksums, and curl|sh installer

Extends the release workflow's matrix to build five targets on tag push:

  • x86_64-unknown-linux-musl → sct-linux-x86_64.tar.gz
  • aarch64-unknown-linux-musl → sct-linux-aarch64.tar.gz (new, native ubuntu-24.04-arm runner, no cross-compile)
  • aarch64-apple-darwin → sct-macos-aarch64.tar.gz
  • x86_64-apple-darwin → sct-macos-x86_64.tar.gz
  • x86_64-pc-windows-msvc → sct-windows-x86_64.zip (new, zipped via PowerShell Compress-Archive)

The release job now generates a single SHA256SUMS file covering every artefact and attaches it to the GitHub release alongside the tarballs.

install.sh is a POSIX-sh installer that users can pipe from curl:

curl -fsSL https://raw.githubusercontent.com/pacharanero/sct/main/install.sh | sh

It auto-detects OS and architecture, fetches the latest release tag, downloads the matching tarball plus SHA256SUMS, verifies the checksum before install, and drops the binary at $HOME/.local/bin (override via $SCT_INSTALL_DIR). Falls back between curl/wget and sha256sum/shasum.

Cargo.toml grows a [package.metadata.binstall] block so cargo binstall sct-rs can download the prebuilt artefacts instead of compiling from source.

Devcontainer (1f00cd1)

  • Add FUNDING.yml to support GitHub Sponsors (df49e39)

  • Fix inaccurate description of Hermes

Hermes is a library first, not a server — the HTTP and MCP interfaces are optional wrappers. It can be embedded in-process with no network overhead. It runs from source code or via Homebrew, not only as a JAR. LMDB is BSD-licensed, not proprietary. Acknowledge the trade-offs: no SQLite ad-hoc queryability, JVM startup cost — but note the runtime performance. (d64d951)

Fix inaccurate description of Hermes (bdbdfec)

  • Merge remote-tracking branch 'origin/main' (e138723)

  • TRUD-automation (#9) (db6181a)

  • Sct trud check: verify local file SHA-256 against TRUD metadata

Previously sct trud check only checked whether a file with the expected name existed in the releases directory — a corrupt or half-downloaded local file would be reported as "up to date". Now, when the file is present, its SHA-256 is re-computed and compared against the TRUD metadata. On match, the verification is stated explicitly in the output. On mismatch, the check exits 2 (same as "new release available") so a check && download shell loop will heal the corruption automatically.

  • Minor tweaks to ETHICS.md (386e158)

  • Split src into lib + bin so integration tests can live under tests/

Adds src/lib.rs that re-exports the existing modules (builder, commands, rf2, schema) as pub, and strips the matching mod declarations from src/main.rs. The binary now depends on the library via use sct_rs::..., enabling integration tests under tests/ and downstream reuse, without changing the visibility or semantics of any item inside the modules.

This is pass 1 of a two-pass refactor; pass 2 will migrate the tests that exercise public/CLI behaviour into tests/ as integration tests while leaving private-function unit tests in their #[cfg(test)] modules.
