go-remote: tool for managing Go source code
go - tool for managing Go source code
DESCRIPTIONAn import path (see go-importpath(1)) denotes a package stored in the local file system. 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:
- BitBucket (Mercurial)
import "bitbucket.org/user/project" import "bitbucket.org/user/project/sub/directory"
- GitHub (Git)
import "github.com/user/project" import "github.com/user/project/sub/directory"
- Google Code Project Hosting (Git, Mercurial, Subversion)
import "code.google.com/p/project" import "code.google.com/p/project/sub/directory"
import "code.google.com/p/project.subrepository" import "code.google.com/p/project.subrepository/sub/directory"
- Launchpad (Bazaar)
import "launchpad.net/project" import "launchpad.net/project/series" import "launchpad.net/project/series/sub/directory"
import "launchpad.net/~user/project/branch" import "launchpad.net/~user/project/branch/sub/directory"
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 <meta> tag in the HTML.
To declare the code location, an import path of the form
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:
denotes the root directory of the Mercurial repository at example.org/user/foo or foo.hg, and
denotes the foo/bar directory of the Git repository at example.com/repo or repo.git.
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 <meta> tag in the document's HTML <head>.
The meta tag has the form:
<meta name="go-import" content="import-prefix vcs repo-root">
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 <meta> 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.
will result in the following request(s):
https://example.org/pkg/foo?go-get=1 (preferred) http://example.org/pkg/foo?go-get=1 (fallback)
If that page contains the meta tag
<meta name="go-import" content="example.org git https://code.org/r/p/exproj">
New downloaded packages are written to the first directory listed in the GOPATH environment variable (see go-path(1)).
The go command attempts to download the version of the package appropriate for the Go release being used. See go-install(1) for more.
