* Add support for plugin options in Babylon
They work similarly to how they work in Babel. e.g.
babylon.parse({
options: [
"plugin1",
["plugin2", { option: true }]
]
});
The inernal api to get an option is
this.getPluginOption("pluginName", "option")
If the plugin isn't defined, it returns undefined.
* Add Babylon option decorators.secoratorsBeforeExport
* Nit
* Update decorators parsing
This commit introduces three changes:
1) Class properties can be decorated
2) Decorators can contain arbitrary expressions, using @(...)
3) The Decorator node type has a new property, "arguments". This
makes it possible do distinguish @dec() and @(dec()), which have
different behaviors because @(dec()) is equivalent to @(dec())().
* Rename Decorator#expression to Decorator#callee
* Add test for @dec()()
* Added optionalExpression types to babylon and babel-types
* OptionalChain transforms bug fix
* Added OptionalExpressions to babel-generator. Fixed OptionalChain Bugs
* Removed 'optionalChain' from newExpression and added test cases
* Added test cases for optionalChain
* Update index.js
* Split exportExtensions into two plugins in babylon
* rename proposal-export-default to proposal-export-default-from
* rename proposal-export-namespace to proposal-export-namespace-from
