For time-traveling gophers.

By go install, we can have just only single dlv. However, dlv of a version can supports some range of go versions, not all go. If you are writing old and new go, managing dlv can be toil.

velde, this command, manages many versions of dlv, install them as needed, and proxies to suitable one for your go!

First, uninstall dlv.

Second, go install.

go install github.com/youta-t/velde

Finally, make symlink to velde as dlv.

ln -s ./velde ~/go/bin/dlv

velde has 2 modes.

When velde is invoked as dlv (via symlink), it perform 2 tasks in order.

1. installs dlv which supports go you using.
2. hands over tasks to the dlv supports your go.

Task 1 will be skipped if you have suitable dlv for your go.

Installed dlv by velde are in ${VELDE_PATH} (default; ~/.velde).

go is searched from ${PATH}.

velde invokes go version as a subprocess to know the version of go which is used, and involes go install as a subprocess (with overwriting GOBIN) to install dlv.

When velde is invoked as any name but dlv, it perform management functions for your dlv.

There are several subcommands.

• velde list: list installed dlv by velde
• velde uninstall: uninstall delve installed by velde
  • Also, you can delete ${VELDE_PATH}/dlv@${VERSION}. It does this.

For each subcommand, dlv's version are in format dlv@v${MAJOR}.${MINOR}.${RELEASE}[-${SUFFIX}].
