+# hosted-git-info
+
+This will let you identify and transform various git hosts URLs between
+protocols.  It also can tell you what the URL is for the raw path for
+particular file for direct access without git.
+
+## Example
+
+```javascript
+var hostedGitInfo = require("hosted-git-info")
+var info = hostedGitInfo.fromUrl("git@github.com:npm/hosted-git-info.git", opts)
+/* info looks like:
+{
+  type: "github",
+  domain: "github.com",
+  user: "npm",
+  project: "hosted-git-info"
+}
+*/
+```
+
+If the URL can't be matched with a git host, `null` will be returned.  We
+can match git, ssh and https urls.  Additionally, we can match ssh connect
+strings (`git@github.com:npm/hosted-git-info`) and shortcuts (eg,
+`github:npm/hosted-git-info`).  GitHub specifically, is detected in the case
+of a third, unprefixed, form: `npm/hosted-git-info`.
+
+If it does match, the returned object has properties of:
+
+* info.type -- The short name of the service
+* info.domain -- The domain for git protocol use
+* info.user -- The name of the user/org on the git host
+* info.project -- The name of the project on the git host
+
+## Version Contract
+
+The major version will be bumped any time…
+
+* The constructor stops accepting URLs that it previously accepted.
+* A method is removed.
+* A method can no longer accept the number and type of arguments it previously accepted.
+* A method can return a different type than it currently returns.
+
+Implications:
+
+* I do not consider the specific format of the urls returned from, say
+  `.https()` to be a part of the contract.  The contract is that it will
+  return a string that can be used to fetch the repo via HTTPS.  But what
+  that string looks like, specifically, can change.
+* Dropping support for a hosted git provider would constitute a breaking
+  change.
+
+## Usage
+
+### var info = hostedGitInfo.fromUrl(gitSpecifier[, options])
+
+* *gitSpecifer* is a URL of a git repository or a SCP-style specifier of one.
+* *options* is an optional object. It can have the following properties:
+  * *noCommittish* — If true then committishes won't be included in generated URLs.
+  * *noGitPlus* — If true then `git+` won't be prefixed on URLs.
+
+## Methods
+
+All of the methods take the same options as the `fromUrl` factory.  Options
+provided to a method override those provided to the constructor.
+
+* info.file(path, opts)
+
+Given the path of a file relative to the repository, returns a URL for
+directly fetching it from the githost.  If no committish was set then
+`master` will be used as the default.
+
+For example `hostedGitInfo.fromUrl("git@github.com:npm/hosted-git-info.git#v1.0.0").file("package.json")`
+would return `https://raw.githubusercontent.com/npm/hosted-git-info/v1.0.0/package.json`
+
+* info.shortcut(opts)
+
+eg, `github:npm/hosted-git-info`
+
+* info.browse(path, fragment, opts)
+
+eg, `https://github.com/npm/hosted-git-info/tree/v1.2.0`,
+`https://github.com/npm/hosted-git-info/tree/v1.2.0/package.json`,
+`https://github.com/npm/hosted-git-info/tree/v1.2.0/REAMDE.md#supported-hosts`
+
+* info.bugs(opts)
+
+eg, `https://github.com/npm/hosted-git-info/issues`
+
+* info.docs(opts)
+
+eg, `https://github.com/npm/hosted-git-info/tree/v1.2.0#readme`
+
+* info.https(opts)
+
+eg, `git+https://github.com/npm/hosted-git-info.git`
+
+* info.sshurl(opts)
+
+eg, `git+ssh://git@github.com/npm/hosted-git-info.git`
+
+* info.ssh(opts)
+
+eg, `git@github.com:npm/hosted-git-info.git`
+
+* info.path(opts)
+
+eg, `npm/hosted-git-info`
+
+* info.tarball(opts)
+
+eg, `https://github.com/npm/hosted-git-info/archive/v1.2.0.tar.gz`
+
+* info.getDefaultRepresentation()
+
+Returns the default output type. The default output type is based on the
+string you passed in to be parsed
+
+* info.toString(opts)
+
+Uses the getDefaultRepresentation to call one of the other methods to get a URL for
+this resource. As such `hostedGitInfo.fromUrl(url).toString()` will give
+you a normalized version of the URL that still uses the same protocol.
+
+Shortcuts will still be returned as shortcuts, but the special case github
+form of `org/project` will be normalized to `github:org/project`.
+
+SSH connect strings will be normalized into `git+ssh` URLs.
+
+## Supported hosts
+
+Currently this supports GitHub, Bitbucket and GitLab. Pull requests for
+additional hosts welcome.
