Export Parser class from Babylon? #22
Description
Can we export the Parser class from Babylon? We are already very close to doing so on this line.
Then Babel plugins would be able to override Parser methods like getTokenFromCode() to add support for new tokens. For example, adding support for a # token:
import * as babylon from "babylon";
babylon.tokTypes.hash = { label: "#", beforeExpr: true };
let {getTokenFromCode} = babylon.Parser.prototype;
babylon.Parser.prototype.getTokenFromCode = function(code) {
if (code === 35) { // '#'
++this.state.pos;
return this.finishToken(babylon.tokTypes.hash);
}
return getTokenFromCode.bind(this)(code);
};At the very least, it would be nice to have some hooks into the different Parser methods.
