Glide: Vendor Package Management for Golang
Are you used to tools such as Cargo, npm, Composer, Nuget, Pip, Maven, Bundler, or other modern package managers? If so, Glide is the comparable Go tool.
Manage your vendor and vendored packages with ease. Glide is a tool for
vendor directory within a Go package. This feature, first
introduced in Go 1.5, allows each package to have a
containing dependent packages for the project. These vendor packages can be
installed by a tool (e.g. glide), similar to
go get or they can be vendored and
distributed with the package.
The Go community now has the dep project to manage dependencies. Please consider trying to migrate from Glide to dep. If there is an issue preventing you from migrating please file an issue with dep so the problem can be corrected. Glide will continue to be supported for some time but is considered to be in a state of support rather than active feature development.
- Ease dependency management
- Support versioning packages including Semantic Versioning
2.0.0 support. Any constraint the
github.com/Masterminds/semverpackage can parse can be used.
- Support aliasing packages (e.g. for working with github forks)
- Remove the need for munging import statements
- Work with all of the
- Support the VCS tools that Go supports:
- Support custom local and global plugins (see docs/plugins.md)
- Repository caching and data caching for improved performance.
- Flatten dependencies resolving version differences and avoiding the inclusion of a package multiple times.
- Manage and install dependencies on-demand or vendored in your version control system.
How It Works
Glide scans the source code of your application or library to determine the needed
dependencies. To determine the versions and locations (such as aliases for forks)
Glide reads a
glide.yaml file with the rules. With this information Glide retrieves
When a dependent package is encountered its imports are scanned to determine
dependencies of dependencies (transitive dependencies). If the dependent project
glide.yaml file that information is used to help determine the
dependency rules when fetching from a location or version to use. Configuration
from Godep, GB, GOM, and GPM is also imported.
The dependencies are exported to the
vendor/ directory where the
can find and use them. A
glide.lock file is generated containing all the
dependencies, including transitive ones.
glide init command can be use to setup a new project,
regenerates the dependency versions using scanning and rules, and
will install the versions listed in the
glide.lock file, skipping scanning,
glide.lock file is not found in which case it will perform an update.
A project is structured like this:
- $GOPATH/src/myProject (Your project) | |-- glide.yaml | |-- glide.lock | |-- main.go (Your main go code can live here) | |-- mySubpackage (You can create your own subpackages, too) | | | |-- foo.go | |-- vendor |-- github.com | |-- Masterminds | |-- ... etc.
Take a look at the Glide source code to see this philosophy in action.
The easiest way to install the latest release on Mac or Linux is with the following script:
curl https://glide.sh/get | sh
On Mac OS X you can also install the latest release via Homebrew:
$ brew install glide
On Ubuntu Precise (12.04), Trusty (14.04), Wily (15.10) or Xenial (16.04) you can install from our PPA:
sudo add-apt-repository ppa:masterminds/glide && sudo apt-get update sudo apt-get install glide
On Ubuntu Zesty (17.04) the package is called
Binary packages are available for Mac, Linux and Windows.
For a development version it is also possible to
go get github.com/Masterminds/glide.
To build from source you can:
- Clone this repository into
$GOPATH/src/github.com/Masterminds/glideand change directory into it
- If you are using Go 1.5 ensure the environment variable GO15VENDOREXPERIMENT is set, for
example by running
export GO15VENDOREXPERIMENT=1. In Go 1.6 it is enabled by default and in Go 1.7 it is always enabled without the ability to turn it off.
This will leave you with
./glide, which you can put in your

they are specified with another package manager or not.

This runs a wizard that scans your dependencies and retrieves information on them to offer up suggestions that you can interactively choose. For example, it can discover if a dependency uses semantic versions and help you choose the version ranges to use.
glide get [package name]
You can download one or more packages to your
vendor directory and have it added to your
glide.yaml file with
$ glide get github.com/Masterminds/cookoo
glide get is used it will introspect the listed package to resolve its
dependencies including using Godep, GPM, Gom, and GB config files.
glide update (aliased to up)
Download or update all of the libraries listed in the
glide.yaml file and put
them in the
vendor directory. It will also recursively walk through the
dependency packages to fetch anything that's needed and read in any configuration.
$ glide up
This will recurse over the packages looking for other projects managed by Glide, Godep, gb, gom, and GPM. When one is found those packages will be installed as needed.
glide.lock file will be created or updated with the dependencies pinned to
specific versions. For example, if in the
glide.yaml file a version was
specified as a range (e.g.,
^1.2.3) it will be set to a specific commit id in
glide.lock file. That allows for reproducible installs (see

glide.yaml files see the documentation.
glide.yaml file does two critical things:
- It names the current package
- It declares external dependencies
glide.yaml file looks like this:
package: github.com/Masterminds/glide import: - package: github.com/Masterminds/semver - package: github.com/Masterminds/cookoo version: ^1.2.0 repo: email@example.com:Masterminds/cookoo.git
The above tells
- This package is named
- That this package depends on two libraries.
The first library exemplifies a minimal package import. It merely gives the fully qualified import path.
When Glide reads the definition for the second library, it will get the repo
from the source in
repo, checkout the latest version between 1.2.0 and 2.0.0,
and put it in
github.com/Masterminds/cookoo in the
vendor directory. (Note
repo can be completely different)
TIP: The version is either VCS dependent and can be anything that can be checked
out or a semantic version constraint that can be parsed by the
github.com/ Masterminds/semver package.
For example, with Git this can be a branch, tag, or hash. This varies and
depends on what's supported in the VCS.
TIP: In general, you are advised to use the base package name for
importing a package, not a subpackage name. For example, use
github.com/kylelemons/go-gypsy and not
Supported Version Control Systems
The Git, SVN, Mercurial (Hg), and Bzr source control systems are supported. This happens through the vcs package.
Frequently Asked Questions (F.A.Q.)
Q: Why does Glide have the concept of sub-packages when Go doesn't?
In Go every directory is a package. This works well when you have one repo containing all of your packages. When you have different packages in different VCS locations things become a bit more complicated. A project containing a collection of packages should be handled with the same information including the version. By grouping packages this way we are able to manage the related information.
Q: bzr (or hg) is not working the way I expected. Why?
These are works in progress, and may need some additional tuning. Please take a look at the vcs package. If you see a better way to handle it please let us know.
Q: Should I check
vendor/ into version control?
That's up to you. It's not necessary, but it may also cause you extra work and lots of extra space in your VCS. There may also be unforeseen errors (see an example).
Q: How do I import settings from GPM, Godep, gom or gb?
There are two parts to importing.
- If a package you import has configuration for GPM, Godep, gom or gb Glide will recursively install the dependencies automatically.
- If you would like to import configuration from GPM, Godep, gom or gb to Glide see
glide importcommand. For example, you can run
glide import godepfor Glide to detect the projects Godep configuration and generate a
glide.yamlfile for you.
Each of these will merge your existing
glide.yaml file with the
dependencies it finds for those managers, and then emit the file as
output. It will not overwrite your glide.yaml file.
You can write it to file like this:
$ glide import godep -f glide.yaml
Q: Can Glide fetch a package based on OS or Arch?
A: Yes. Using the
arch fields on a
package, you can specify
which OSes and architectures the package should be fetched for. For
example, the following package will only be fetched for 64-bit
- package: some/package os: - darwin arch: - amd64
The package will not be fetched for other architectures or OSes.
