happner-terminal
Terminal for happner (comes bundled).
Provides a prompt into your running mesh.
Not a remote prompt.
To activate
in the config:
meshConfig = {
...
components: {
terminal: {},
...
...
}
...
}
in the mesh initialization:
// start your meshnode
// good practice...
var happner = require('happner'); //
happner.start( require('./your/meshConfig.js').config )
.then(function(mesh) {
// meshnode is up, start the terminal
mesh.exchange.terminal.start({
prefix: '> ', // the prompt
help: true // show the intro help
}, function optionalCallback() {}) // or .then... (promise)
})
.catch...
Note: By putting the terminal component first, other components running their startMethods can detect and use the terminal. eg. To install commands into it.
Typical startMethod installing a command into the terminal
This in some other mesh component:
Module.prototype.start = function($happn, callback) {
var terminal;
if (terminal = $happn.exchange.terminal) {
// terminal is present.
terminal.register('hello', {
// creates a 'hello' command available in the terminal
description: 'example',
help: '\n\n\n',
run: function(args, callback) {
// if you don't call the callback you dont het the prompt back, ever!
// (and you'll need to kill the process from the outside)
callback(null, '\nHello ' + args[0] + '.\n');
},
autoComplete(args, callback) {
var possible = ['world',
'solarsystem',
'galaxy',
'universe']; // use args to determine next possibilities
callback(null, possible);
}
});
}
callback(null);
}
