goven

The golang module vendoring tool.

Why?

Go has vendoring functionality built-in, so why we need goven?

Yes, go tooling has vendoring functionality. However some go tools do not respect vendored modules. For example, go install doesn't take into account vendored modules in the module being installed.

Also some of your modules might have replace directives in go.mod file. This would make your module non usable for go get or go install commands.

If simple go vendoring is working for you, please keep using it.

How?

How goven is vendoring modules?

Goven copies all dependencies source code into the code of the module, it also fixes all package references in the code and fixing go.mod file.

To use goven for vendoring, the module should be developed in one repository but released via the other repository.

Installation

go install github.com/specgen-io/goven@v0.0.10

Usage

There are two commands implemented by goven: vendor and release.

The vendor command vendors the module code and places it to the local file system.

While the release command does the same as vendor command but also pushes vendored code to the Github.

Vendor

To vendor only replace directives in the module, change name of the module to github.com/example/mymodule run this command in the module root folder:

goven vendor -name github.com/example/mymodule

The module code with vendored dependencies will be placed into out subfolder. The code in out subfolder will be ready for publishing at github.com/example/mymodule.

The output folder could be changed by -out option:

goven vendor -name github.com/example/mymodule -out ~/mymodule

To vendor both replace and require directives, run following:

go mod vendor    # <- this is still needed
goven vendor -name github.com/example/mymodule -required

Vendored modules are by default placed to goven subfolder of the module. This can be change via -vendor option:

goven vendor -name github.com/example/mymodule -required -vendor vendored

Check goven vendor -help to learn about all arguments.

Release

This command will vendor code rename the module into github.com/example/mymodule and push it to the corresponding Github repository:

goven release -name github.com/example/mymodule

In the case below the vendored module will be named github.com/example/mymodule/v2 and also it will be pushed into v2 folder of the repository as go requires:

goven release -name github.com/example/mymodule/v2

The release command can create and push tag into the release repository. This could be done via -version option:

goven release -name github.com/example/mymodule/v2 -version v2.0.0

The other options like -module, -required, -out, -vendor are working for release command the same way as for vendor command.

Committing and pushing to Github repository requires authorization, options github-name, github-email, github-user and github-token should be used to provide credentials and commit author's info. Alternatively these options could be set via GITHUB_NAME, GITHUB_EMAIL, GITHUB_USER and GITHUB_TOKEN environment variables.

Check goven release -help to learn about all arguments.
