Listening for bower events, while using yeoman in non cli environment

[apdarshan]

Thanks for abstracting out Base object for non-cli support. I am building an extension for Adobe brackets with my yeoman generator. My concern is How/Where do I listen for bower log, errror, end events.

    _installBower: function (cb) {
        this.log("Running bower install...");
        /*reads bower.json and installs*/
        bower.commands.install([], {}, {directory : "./", cwd: process.cwd()}).on('error', function (error) {
            this.log("BOWER error::" + JSON.stringify(error));
            cb();
        }.bind(this)).on('log', function (log) {
            this.log("BOWER LOG::" + JSON.stringify(log));
            this.emit("log", log); // TODO::
        }.bind(this)).on('end', function (installed) {
            this.log("BOWER END::" + JSON.stringify(installed));
            cb();
        }.bind(this));
    },

    bowerInstallHelper: function(){
        if (!this.options['skip-install']) {
            var cb = this.async();
            this._installBower(cb);
        }
    }

As every Adobe Brackets user may not have yeoman/bower installed globally, I have bower installed locally using generator's package.json and requiring it in generator-myframewrlk/app/index.js.

I have emit method defined in my Adapter as below,

 MyAwesomeAdapter.prototype.emit = function(event, data) {
    console.log(event); // not coming here
    var handlers = this.eventHandlers[event];
    handlers.forEach(function(handler, i) {
        handler(data);
    });
};

Hi, the issue is there's no emit method on an Adapter: https://github.com/yeoman/generator/blob/master/lib/env/adapter.js

What would you like exposed from the bower API? (And does bower expose it through a programmatic API?)

@SBoudrias I have my own adapter with emit method defined in it, as per this wiki and #383

What would you like exposed from the bower API? (And does bower expose it through a programmatic API?)

Yes bower fires below events, I am getting below logs.

bower.commands.install([], {}, {directory : "./", cwd: process.cwd()}).on('error', function (error) {
            this.log("BOWER error::" + JSON.stringify(error));
        }.bind(this)).on('log', function (log) {
            this.log("BOWER LOG::" + JSON.stringify(log));
        }.bind(this)).on('end', function (installed) {
            this.log("BOWER END::" + JSON.stringify(installed));
        }.bind(this));

I just need to get notified(in my adapter) whenever bower log, error & end events occurs. @artoale

What I mean is that you can define an emit method, but the Yeoman core doesn't interface its internal emit to your Adapter emit method.

[apdarshan]

Yes thats what I needed @SBoudrias.

How about this? in env

generator.on('log', this.adapter.emit.bind(this.adapter, "log"));
generator.on('error', this.adapter.emit.bind(this.adapter, "error"));
generator.on('end', this.adapter.emit.bind(this.adapter, "end"));

We need to write down an ideal API to resolve this issue and then make it actionable so someone can really fix it.
