プロジェクトの歴史

The official README presents attempt as a focused CLI for retrying commands that may fail temporarily. The Cargo metadata names the crate attempt-cli, exposes the binary as `attempt`, uses the 2021 Rust edition, and describes the project as public-domain software under the Unlicense.

The public release history is short: GitHub releases show v1.0.1 and v1.1.0 in September 2025, followed by v1.1.1 in January 2026. That makes it a relatively young tool compared with the older Unix packages in this batch.

採用の歴史

The README documents installation through Cargo and Homebrew, placing attempt in the modern Rust CLI distribution pattern: publish a crate for Rust users and a Homebrew formula for macOS package-manager users.

Its adoption story is use-case-led rather than ecosystem-led. The manual explicitly compares one case to wait-for-it.sh: waiting for services in docker-compose-like environments when the user is not restricted to Bash. It also targets robust scripts that call temporarily unavailable services.

使われ方

The basic invocation is `attempt [BACKOFF] [OPTIONS] [COMMAND]...`. Official examples retry database migrations when output contains `server not ready`, use exponential backoff, change attempt counts, add jitter, and separate attempt arguments from child-command arguments with `--`.

The manual explains the mental model: classify failures with retry policy, choose a backoff schedule, set a retry limit, and optionally use exponential backoff to start aggressively while backing off during persistent outages.

パッケージ好きにとっての重要性

attempt is package-nerd interesting because it turns a shell pattern into a dedicated binary. Instead of every script growing its own retry loop, timeout handling, jitter, and output predicate checks, the package offers a small auditable command.

It is also a tidy example of a Rust CLI whose package name and binary name differ: Homebrew packages attempt-cli, Cargo installs attempt-cli, but users run `attempt`.
