## Project history and usage

gomodifytags is a Go developer tool for adding, updating, removing, and formatting struct field tags. Its importance is editor workflow: it automates a repetitive Go refactoring task that otherwise invites typo-prone manual edits.

### Project history

The repository was created in January 2017 by Fatih Arslan. The README describes a focused command that modifies tags in Go structs by file, struct, field, line, offset, or all structs, with dry-run output by default and a write flag for in-place edits.

The tool was designed for editor integration as much as terminal use. The README lists vim-go, Atom go-plus, vscode-go, Acme integration, emacs-go-tag, and TextMate2 support, which explains why a small CLI became widely known in the Go editing ecosystem.

### Adoption history

GitHub release pages show a 1.x release series, including v1.17.0 in July 2024. Homebrew and Nix package metadata in the batch input show the tool being distributed outside go install, which is useful for editor plugin dependencies and reproducible workstation setup.

The GitHub repository metadata showed thousands of stars by June 2026, consistent with a mature, editor-adjacent Go utility rather than a large standalone application.

### How it is used

Typical usage points gomodifytags at a Go source file and identifies the fields to change using -struct, -field, -line, -offset, or -all. Users then add or remove tag keys and options such as json, xml, omitempty, validation tags, or custom value templates.

Because it prints changes unless -w is supplied, the CLI works well as both a terminal tool and a backend for editors that preview or apply edits at the cursor.

### Why package nerds care

gomodifytags is package-nerd catnip because it turns a language convention, Go struct tags, into a stable external executable that editors can share. That keeps editor plugins thin and lets package managers ship one implementation of the tag-rewriting logic.

### Timeline

- 2017: GitHub repository created.
- 2017: v1.0.0 tag appears in the Git tag list.
- 2021: GitHub release pages show several 1.x releases, including v1.14.0, v1.15.0, and v1.16.0.
- 2024: GitHub release pages show v1.17.0.

### Related projects

- vim-go, vscode-go, go-plus, emacs-go-tag, Acme tooling, and TextMate2 integrations are listed by the README as supported editor surfaces.
- Go's reflect.StructTag convention is the language feature gomodifytags edits around.
