Some Gentoo CLI tools I wrote for myself.

g2 includes a set of tools for working with Gentoo Manifest files.

The manifest command group handles operations related to Manifest files.

Updates or inserts a Manifest entry for a file downloaded from a URL. This command streams the file, calculates the specified checksums, and updates the Manifest file in the specified directory (or specific file path).

Usage:

g2 manifest [flags] upsert-from-url <url> <filename> <manifestFileOrDir>

Arguments:

• <url>: The HTTP/HTTPS URL of the file to download.
• <filename>: The filename to record in the Manifest (typically the distfile name).
• <manifestFileOrDir>: The path to the Manifest file or the directory containing it (e.g., the ebuild directory).

Flags:

The following flags control which checksums are calculated. Note that BLAKE2B and SHA512 are enabled by default.

• -blake2b (default: true): Calculate BLAKE2B checksum.
• -blake2s (default: false): Calculate BLAKE2S checksum.
• -md5 (default: false): Calculate MD5 checksum.
• -rmd160 (default: false): Calculate RMD160 checksum.
• -sha1 (default: false): Calculate SHA1 checksum.
• -sha256 (default: false): Calculate SHA256 checksum.
• -sha3_256 (default: false): Calculate SHA3-256 checksum.
• -sha3_512 (default: false): Calculate SHA3-512 checksum.
• -sha512 (default: true): Calculate SHA512 checksum.

Example:

To download a package, calculate SHA256 in addition to defaults, and update the Manifest in the current directory:

g2 manifest -sha256=true upsert-from-url https://example.com/software-1.0.tar.gz software-1.0.tar.gz .
