dep

Interactively initialize deployer in the local path (use a framework template with --template=template)

$ dep init

$ dep deploy [hostname]

$ dep rollback

$ dep ssh [hostname]

$ dep list

$ dep run "[command]"

$ dep help [command]

dep command [<flags>] [<args>...]

init [<import path constraints>]
    Initialize project, scan imports, generate Gopkg.toml

ensure [<-vendor-only>] [<-add pkg[@ver]>...] [<-update pkg[@ver]>...]
    Resolve deps, update Gopkg.lock, sync vendor/

status [<-v>]
    Report status of dependencies vs imports, show updates

version
    Print dep version

check
    Verify Gopkg.toml, Gopkg.lock match vendor/

prune
    Remove unused dependencies from Gopkg.toml (experimental)

dep is a tool for managing dependencies of Go projects. It declares dependencies in a Gopkg.toml manifest file, resolves them to exact versions in Gopkg.lock, and vendors sources into vendor/ for reproducible builds.

Workflow starts with dep init to analyze imports and generate initial files. dep ensure downloads, updates Gopkg.lock, and vendors dependencies, supporting overrides and constraints. dep status shows outdated packages, while dep check verifies consistency.

dep supports import analysis, version solving with constraints like semver, branches, and commits. It integrates with go build via GOPATH or vendor/.

Deprecated since Go 1.11 modules (go.mod/go.sum), dep is in maintenance mode. Migrate with go mod init and go mod vendor.

dep is deprecated and unsupported for new projects. Use Go modules: go help modules. May conflict with go mod in same repo.

Gopkg.toml: deps manifest with constraints
Gopkg.lock: solved versions checksums
vendor/: source copies

From dep: go mod init, go mod tidy, go mod vendor if needed

Announced 2016 by Go team as official dep mgmt experiment. v0.1 2016, v0.5.0 2018 (stable). Maintenance mode Nov 2019 after Go 1.13 modules.
