YUI Compressor 2.4.8 failed on jQuery 2.2 #234

stepand76 · 2016-01-15T22:48:30Z

When I try to pass original uncompressed jquery-2.2.0.js file to YUI Compressor 2.4.8 I get following output (with jquery-2.1.4.js it works):

same problem here!

stepand76 · 2016-01-27T12:17:13Z

Any chance that this will be fixed?

mgol · 2016-01-27T13:06:40Z

This is a bug in YUI Compressor. Could you report it to them?

stepand76 · 2016-01-27T13:08:17Z

It is reported to the YUI Compressor, isn't it?

mgol · 2016-01-27T13:45:56Z

I'm sorry, for a moment I thought it was reported against jQuery... I commented too fast, please disregard.

IceReaper · 2016-01-27T14:13:41Z

Problem: "throws" and several other names are marked as reserved in YUI, while jquery assumes they are not and uses them.
Location: https://github.com/yui/yuicompressor/blob/c41a4b504a996b9c2a49b497e2f61ba7998b0408/src/org/mozilla/javascript/TokenStream.java

Step1: Make a list of all wrongly-reserved-names plus proof-link
Step2: Remove them and make a PR or fork of YUI and / or jQuery, depending on who violates the JS-RFC. Shouldn't take that much time to do.

If there is already such PR, link it here. Haven't found one.

tml · 2016-02-15T04:45:50Z

To clarify - "throws" and several other names are marked as reserved in JAVASCRIPT, and YUICompressor is respecting that declaration.

The trick that makes it a bit harder is that YUICompressor isn't tied to a specific version of Java/ECMAScript, and in older versions, these are illegal identifiers. So you have to allow it for ES5+ while not allowing it in ES4 and earlier; while keeping in mind that there's no standardized way for a bit of JavaScript code to declare which version of JS/ES it thinks it wants to be.

If you have ideas for solving all of those problems in the same go, I'd love to hear about them! :)

IceReaper · 2016-02-23T13:30:15Z

As an ugly workaround it could be possible to do a replacement before / after minification. The replacement-logic could be triggered by a simple --language-version parameter.

bashor · 2016-03-21T11:30:03Z

Same issue with kotlin.js. Should I report separate issue?

To reproduce download kotlin-compiler-1.0.1.zip and see kotlinc/lib/kotlin-jslib.jar/kotlin.js

stepand76 · 2016-03-21T11:48:10Z

Well, any chance this to be fixed?

saleehk · 2016-03-24T12:10:31Z

meyermc · 2016-03-28T19:24:26Z

I have this same issue with pdf.js, I tried to give them a pull request and they rejected it, pointing out that 'char' is not a reserved word in ES5.1 and that ECMSScript permits reserved words ('catch', 'delete') as property names. So, declaring a reserved word variable or function is illegal but assigning a function literal to a reserved word property is valid.

varun1987shrivastava · 2016-09-19T11:49:25Z

I think this is related to the keywords that js file uses clash with some in-build keywords of the compressor. you can try using the minified version of the js file to get rid of this issue. this is something i did in my project when using jquery-3.1.0.

LeiZeng · 2016-12-27T02:29:33Z

A work around by using babel plugins:

nueverest · 2017-02-28T01:00:17Z

Still breaking for jquery is there a reason this is closed?

That's correct - jquery 3.3.1 is not valid ECMAScript 3 syntax; YUICompressor does not support anything else at this time.

I have solved with custom methods, i have used a fork https://github.com/MrD0llaro/yuicompressor
