Glide vendor cleaner

Glide vendor cleaner

Important Note!!!

Before using this tool be sure that cleaning and commiting vendored directories to VCS does not violate the licenses of the packages you're vendoring.

For a detailed explanation on why Glide doesn't do this see here

Description

This tool will help you removing from the project vendor directories all the files not needed for building your project. By default it'll keep only needed packages (returned by the glide list command) and all the files inside them. If you want to keep only source code (including tests) files you can provide the --only-code option. If you want to remove also the go test files you can add the --no-tests option.

By default glide-vc doesn't remove:

• files that are likely to contain some type of of legal declaration or licensing information (to remove them use the --no-legal-files option)
• nested vendor directories. Doing this will change compilation and runtime behavior of your project because only the top level vendored dependencies will be used for compilation. If these are at a different revision (from the one provided inside nested vendor directories) they can cause compilation problems or runtime misbehiaviours. On the other side, keeping nested vendor directories can cause compilation problems like this one.

Vendoring additional tools

In order to vendor tools, some projects will specify packages in their glide.yaml that aren't imported by the project. These packages will be installed and registered in the glide.lock file (but this behavior may change in the future).

By default glide-vc uses the output of the glide list command to retrieve the packages needed by your project. Since glide list uses your projects imports it will not include the tools contained in glide.lock.

Using the --use-lock-file option will make glide-vc use the packages list from glide.lock instead of the one provided by glide list, preserving the tool packages.

Instead of vendoring these tools using glide and using the glide-vc --use-lock-file option, a suggestion (since there isn't a common accepted practice) is to vendor additional project tools using other scripts/tools and perhaps not inside the vendor directory but in another project's path and use the vendor directory just for go dependencies (or if you want to keep them inside vendor then run your tool after glide-vc). See also this discussion.

Install

go get github.com/sgotti/glide-vc

Run

glide vendor cleaner

Usage:
  glide-vc [flags]

Flags:
      --dryrun            just output what will be removed
      --keep value        A pattern to keep additional files inside needed packages. The pattern match will be relative to the deeper vendor dir. Supports double star (**) patterns. (see https://golang.org/pkg/path/filepath/#Match and https://github.com/bmatcu
k/doublestar). Can be specified multiple times. For example to keep all the files with json extension use the '**/*.json' pattern. (default [])
      --no-legal-files    remove also licenses and legal files
      --no-test-imports   remove also testImport vendor directories. Works only with --use-lock-file
      --no-tests          remove also go test files (requires --only-code)
      --only-code         keep only source code files (including go test files)
      --use-lock-file     use glide.lock instead of glide list to determine imports

You have to run glide-vc, or (if glide is installed) glide vc inside your current project root directory.

To see what it'll do use the --dryrun option.

Examples

Tests removal of all unneeded packages.

glide-vc --dryrun

Do it

glide-vc

Keep only source code (including tests) files.

glide-vc --only-code

Keep only source code without go tests.

glide-vc --only-code --no-tests

Keep only source code without go tests and also remove all licenses and legal files.

glide-vc --only-code --no-tests --no-legal-files
