プロジェクトの歴史

The official repository describes Delve's goal as a simple, full-featured debugger for Go that stays out of the user's way. GitHub repository metadata places the public project in May 2014, during the period when Go users were outgrowing general-purpose debugger workflows and needed tooling that understood Go runtime behavior.

Delve's documentation grew around a command family rather than a single mode: dlv debug, exec, attach, core, test, trace, replay, connect, dap, and related subcommands. That breadth made it useful both as an interactive terminal debugger and as the debug engine behind editors.

採用の歴史

Delve became the practical default debugger for Go because it is distributed as a Go command, publishes prebuilt binaries, and exposes integrations for plugins, GUIs, and DAP clients. The official installation docs document go install, binary releases, and building from the repository.

The release feed shows ongoing maintenance through the 1.27.0 release in June 2026, which matters for Go tooling because debugger support must track compiler, runtime, OS, and architecture changes.

使われ方

Typical CLI use starts with dlv debug for the package in the current directory, dlv test for test binaries, dlv exec for an existing binary, or dlv attach for a running process. The usage docs emphasize controlling execution, evaluating variables, and inspecting goroutine, thread, and CPU register state.

In editor workflows, Delve commonly runs as a headless debug server or DAP server. That lets IDEs and editors provide breakpoints and stepping while reusing the same Go-specific debugger backend.

パッケージ好きにとっての重要性

Delve is interesting to package maintainers because it is both a developer CLI and a moving compatibility target for the Go toolchain. A stale debugger package can fail even when ordinary Go builds still work.

Its packaging footprint is also a marker of Go's maturation: once a language has a dedicated debugger in every major package manager, the ecosystem has moved beyond compile-and-print debugging as the default developer experience.
