dep command [options]

dep was the official dependency management tool for Go before Go modules became the standard. It manages project dependencies through Gopkg.toml and Gopkg.lock files, ensuring reproducible builds.
The tool resolves transitive dependencies, handles version constraints, and vendors dependencies in the vendor directory. The ensure command is the primary interface for adding, updating, and synchronizing dependencies.
dep uses semantic import versioning and supports various version constraint syntaxes including semver ranges, branches, and revisions.

Superseded by Go modules (go mod) in Go 1.11+. New projects should use Go modules. Migration path available from dep to modules. Only supports projects in GOPATH.

dep was developed by the Go community and released in 2016 as the official experiment in dependency management. It served as a bridge solution until Go modules were introduced in Go 1.11 (2018), after which dep was placed in maintenance mode.
