How to set flags in ember-cli, other than environment?

Question

This is currently possible:

ember build --environment=production

... and I would like to do something like this instead:

ember build --environment=production --baseurl=foo

but config/environment.js only gets passed in the value of environment.

Is it possible to get the value of the other options passed in at the command line too?

Answer 1

You could set environment variables the old fashioned way (export WHATEVER=wee) from terminal or as part of a build script, then reference them in your Brocfile.js via node with process.env.WHATEVER. After that, it would be a matter of having broccoli do whatever it is you needed to do with them. You could pre-process files and replace strings, for example.

... just a suggestion. Not sure if that's what you're looking for or not.

Answer 2

It appears that this is not allowed:

Looking in node_modules/ember-cli/lib/commands/build.js, we see:

availableOptions: [
  { name: 'environment', type: String, default: 'development' },
  { name: 'output-path', type: path, default: 'dist/' }
],

... and in node_modules/ember-cli/lib/models/command.js

this.availableOptions.forEach(function(option) {
  knownOpts[option.name] = option.type;
});

... which together mean that any options that are not defined, for each subcommand of ember, get discarded.
