Mercurane

Easy Node.JS Hg wrapper with support for SSH keys. By default, the Hg CLI tool will only use the SSH key of the current user (e.g. $HOME/.ssh/id_dsa).

In order to be able to use Hg with an arbitrary SSH key, a wrapper shell script to invoke ssh -i <key> must be written and the ui.ssh option must point to that script (--config ui.ssh=).

Mercurane wraps all this plumbing for you. Simply pass the SSH private key you wish to run Hg with as a string argument and let Mercurane do the rest. Mercurane will clean up the temporary wrapper script after it is done.

Installation

Mercurane is available in NPM. npm install mercurane

Example

  var fs = require('fs')
  var mercurane = require('mercurane')
  var path = require('path')

  // Use current working dir
  var baseDir = process.cwd()
  // Read private key from ~/.ssh/id_dsa
  var privKey = fs.readFileSync(path.join(process.env.HOME, '.ssh/id_dsa'), 'utf8')

  mercurane.run(baseDir, privKey, "hg clone ssh://[e-mail]/petrocloud/test",
    function(err, stdout, stderr, exitCode) {
    if (err) {
      console.log("An error occurred: " + stderr)
      process.exit(1)
    }

    console.log("Hg clone complete!")
  })

Mercurane comes with tests. To run, simply execute npm test.
