Go Module downloader

moddown is a simplified version of fetch_repo. It focuses on downloading a module using go mod download. Unlike fetch_repo, this tool does not create a dummy module and uses the -modcacherw flag to make the cache writable (removable), so it requires at least Go 1.14.

Usage

The basic functionality of moddown includes:

• downloading a module (by calling go mod download under the hood)
• checking the module sum against a known value
• copying files to a destination directory

./moddown -sum h1:snD5ODyv4c9DOBBZh645dy/TziVHZivuFtRRMZP8zK8= -dest ./emperror emperror.dev/errors@v0.4.2

moddown can also use existing module information and delegate downloading to the Go tool:

go mod download -modcacherw -x -json emperror.dev/errors@v0.4.2 > mod.json
./moddown -sum h1:snD5ODyv4c9DOBBZh645dy/TziVHZivuFtRRMZP8zK8= -f mod.json

# OR pipe from stdin directly

go mod download -modcacherw -x -json emperror.dev/errors@v0.4.2 | ./moddown -v -sum h1:snD5ODyv4c9DOBBZh645dy/TziVHZivuFtRRMZP8zK8= -f -

Last, but not least: you can enable verbose logging with -v.
