accent

Installer and updater for Accent CMS.

The crate builds one binary, accentup. It downloads the release archive for your platform from AccentCMS/accent, verifies it, and places the accent binary where the official install scripts put it. It is the same job install.sh and install.ps1 do at that repository, as a signed, cross-platform binary instead of a shell script.

The installer is called accentup, not accent, so that cargo install accent cannot drop a binary in ~/.cargo/bin that shadows the product on your PATH.

Install

cargo install accent
accentup install

Without a Rust toolchain, use the shell installers from the dist repository:

curl -fsSL https://raw.githubusercontent.com/AccentCMS/accent/main/install.sh | sh

irm https://raw.githubusercontent.com/AccentCMS/accent/main/install.ps1 | iex

Usage

accentup                                  # same as `accentup install`
accentup install [--version 0.25.0] [--force] [--dry-run]
accentup update  [--force]
accentup uninstall [--purge]
accentup which

Global flags: --dir PATH to choose the install directory, --quiet to print only warnings and errors.

Versions are accepted with or without the v (0.25.0 and v0.25.0 are the same release). Only v0.22.0 and later are published.

Variable	Effect
`ACCENT_VERSION`	Version to install (same as `--version`)
`ACCENT_FORCE`	Any value but empty or `0` means `--force`
`ACCENT_INSTALL_DIR`	Where the binary goes (same as `--dir`)
`ACCENT_REPO`	Repository to download from, default `AccentCMS/accent`

An explicit flag always wins over its variable.

Where things go

	Install directory
Linux, macOS	`~/.local/bin`
Windows	`%LOCALAPPDATA%\accent`

These are the directories the shell installers use; matching them keeps accentup and install.sh managing one installation rather than two.

uninstall removes the binary. uninstall --purge also deletes the user-level state the product writes — the licence key in ~/.config/accent/ and the cached development certificate — but never the install directory itself, which is shared with other tools.

After installing, accentup warns if the install directory is not on your PATH, and if accent resolves to some other binary that shadows the one it just wrote.

Verification

Every release publishes checksums-<version>.txt covering all archives, and a detached OpenPGP signature checksums-<version>.txt.asc made with the Accent CMS release signing key. accentup checks both, in this order:

the signature over the checksums file, against the key compiled into the binary from release-signing-key.asc;
the SHA-256 of the downloaded archive, against that checksums file.

Neither step is optional and there is no flag to skip them. Verification runs in-process, so unlike install.sh — which falls back to checksum-only when gpg is not installed — a missing tool cannot weaken it. The trust root is never fetched over the network.

Key fingerprint, pinned in src/verify.rs and asserted against the embedded key by the test suite:

C019 7617 BAE7 5201 9693  A17E 9537 7BC8 B27F F227

To verify by hand:

gpg --import release-signing-key.asc
gpg --verify checksums-v0.25.0.txt.asc checksums-v0.25.0.txt
sha256sum -c --ignore-missing checksums-v0.25.0.txt

Supported targets

x86_64 and aarch64, on Linux (gnu), macOS and Windows (msvc). There is no musl build; on a musl host, build Accent CMS from source.

Development

cargo test              # offline: unit tests and CLI tests
cargo test -- --ignored # also downloads and installs a real release
cargo clippy --all-targets -- -D warnings

The layout follows the install flow: platform (which asset), release (which version, and the URLs), net (fetch it), checksums and verify (is it genuine), archive (unpack it), install (place it, PATH warnings), commands (the flow itself), cli and main (arguments).

To test against a fork or a staging repository with the same asset layout, set ACCENT_REPO=owner/name. Swapping the trust root means replacing release-signing-key.asc and the fingerprint in src/verify.rs; the tests fail if the two disagree.
