Certain import paths also describe how to obtain the source code for the package using a revision control system. A few common code hosting sites have special syntax: .TP .B BitBucket (Mercurial) .Vb 4 \&import "bitbucket.org/user/project" \&import "bitbucket.org/user/project/sub/directory" .Ve .TP .B GitHub (Git) .Vb 4 \&import "github.com/user/project" \&import "github.com/user/project/sub/directory" .Ve .TP .B Google Code Project Hosting (Git, Mercurial, Subversion) .Vb 4 \&import "code.google.com/p/project" \&import "code.google.com/p/project/sub/directory" .Ve .Vb 4 \&import "code.google.com/p/project.subrepository" \&import "code.google.com/p/project.subrepository/sub/directory" .Ve .TP .B Launchpad (Bazaar) .Vb 4 \&import "launchpad.net/project" \&import "launchpad.net/project/series" \&import "launchpad.net/project/series/sub/directory" .Ve .Vb 4 \&import "launchpad.net/~user/project/branch" \&import "launchpad.net/~user/project/branch/sub/directory" .Ve .P For code hosted on other servers, import paths may either be qualified with the version control type, or the go tool can dynamically fetch the import path over https/http and discover where the code resides from a tag in the HTML. To declare the code location, an import path of the form .Vb 6 \& repository.vcs/path .Ve specifies the given repository, with or without the .vcs suffix, using the named version control system, and then the path inside that repository. The supported version control systems are: .TP .B Bazaar .bzr .TP .B Git .git .TP .B Mercurial .hg .TP .B Subversion .svn .P For example, .Vb 6 \& import "example.org/user/foo.hg" .Ve denotes the root directory of the Mercurial repository at example.org/user/foo or foo.hg, and .Vb 6 \& import "example.org/repo.git/foo/bar" .Ve denotes the foo/bar directory of the Git repository at example.com/repo or repo.git. When a version control system supports multiple protocols, each is tried in turn when downloading. For example, a Git download tries git://, then https://, then http://. If the import path is not a known code hosting site and also lacks a version control qualifier, the go tool attempts to fetch the import over https/http and looks for a tag in the document's HTML
. The meta tag has the form: .Vb 6 \& .Ve The import-prefix is the import path corresponding to the repository root. It must be a prefix or an exact match of the package being fetched with "go get". If it's not an exact match, another http request is made at the prefix to verify the tags match. The vcs is one of "git", "hg", "svn", etc, The repo-root is the root of the version control system containing a scheme and not containing a .vcs qualifier. For example, .Vb 6 \& import "example.org/pkg/foo" .Ve will result in the following request(s): .Vb 6 \& https://example.org/pkg/foo?go-get=1 (preferred) \& http://example.org/pkg/foo?go-get=1 (fallback) .Ve If that page contains the meta tag .Vb 6 \& .Ve the go tool will verify that https://example.org/?go-get=1 contains the same meta tag and then git clone https://code.org/r/p/exproj into GOPATH/src/example.org. New downloaded packages are written to the first directory listed in the GOPATH environment variable (see \fBgo-path\fP(1)). The go command attempts to download the version of the package appropriate for the Go release being used. See \fBgo-install\fP(1) for more. .SH AUTHOR .PP This manual page was written by Michael Stapelberg
