## プロジェクトの歴史と使われ方

GCI is a Go command-line formatter focused on deterministic import ordering. Its README describes it as a tool that controls Go package import order and makes that order deterministic.

The project exists in the same formatting niche as gofmt and goimports, but its distinguishing feature is configurable import sections for teams that want more structure than default Go formatting provides.

### プロジェクトの歴史

The official GitHub repository was created on July 15, 2020, and the first listed GitHub release, v0.1, was published on July 21, 2020.

The README documents steady feature evolution in the 0.x line, including C import block handling since v0.9.0 and a v0.10.0 command-line change requiring repeated -s/--section flags for multiple sections.

### 採用の歴史

GCI adoption is clearest in Go tooling workflows rather than end-user applications. Its README points CI users toward golangci-lint, and the repository includes a .golangci.yml that enables the gci linter alongside gofmt, gofumpt, and goimports.

Official GitHub repository metadata showed several hundred stars and dozens of forks by mid-2026, a modest but real signal for a specialized Go formatter.

### 使われ方

The README recommends installing with go install github.com/daixiang0/gci@latest or with an explicit version. The CLI provides print, write, list, and diff modes so it can either report formatting drift or rewrite files in place.

GCI groups imports into sections such as standard, default, custom prefix, blank, dot, alias, and localmodule. Local module detection reads go.mod or go.work in the directory where gci is invoked.

### パッケージ好きにとっての重要性

GCI is package-nerd relevant because import sorting is a tiny behavior that creates outsized diff churn in Go repositories. Pinning a deterministic formatter in package managers and CI makes formatting a reproducible build-adjacent rule instead of a reviewer preference.

Its section model gives teams a stricter import taxonomy than goimports alone, which makes it useful in repositories that care about separating standard-library, third-party, local-module, and custom-prefix imports.

### タイムライン

- 2020: Repository created on July 15
- 2020: v0.1 released on July 21
- 2022: v0.9.0 released on November 25
- 2023: v0.10.0 released on March 10
- 2026: v0.14.0 released on February 28

### Related projects

- The README explicitly positions GCI near goimports by noting that it allows more custom formatting than goimport does.
- The repository configuration and README connect GCI to golangci-lint, gofmt, gofumpt, and goimports in normal Go CI formatting workflows.
