Question 1

How to install gup on Windows?

Accepted Answer

Use winget with 'winget install --id nao1215.gup' or download packages from the release page, but note that Go must be installed separately as gup relies on the go command. The README also mentions .deb, .rpm, and .apk formats for Linux systems.

Question 2

gup vs using go install directly for updates?

Accepted Answer

gup speeds up updates by running them in parallel and adds features like selective updates, export/import, and channel control, whereas go install updates one binary at a time and lacks these management tools. gup is essentially a wrapper that enhances go install's update process.

Question 3

Can gup update binaries from private repositories?

Accepted Answer

Likely yes, as it uses the go command internally, which supports private repos if configured with proper authentication (e.g., via GOPRIVATE). However, the README doesn't explicitly detail this, so users may need to ensure their Go environment is set up correctly.

Question 4

How to exclude specific binaries from gup update?

Accepted Answer

Use the --exclude option (e.g., 'gup update --exclude=gopls,golangci-lint') to skip updating listed binaries, as shown in the README. This allows fine-grained control without modifying the tool list permanently.

Question 5

Does gup work with tools installed via Homebrew?

Accepted Answer

No, gup only manages binaries installed via go install, so tools installed through Homebrew or other system package managers are not recognized. The README focuses on $GOPATH/bin or $GOBIN directories.

Question 6

How to sync Go tools across machines with gup?

Accepted Answer

Run 'gup export' to create a gup.json file with current binaries and versions, then use 'gup import' on another machine to install them. The README provides examples with --file and --output options for custom paths.
