I'm trying to run:
js appname\scripts\compress.js
And it's just sitting there. Is there any way to debug this process? I
let it go for at least 10 minutes with no output to the console.
Are there any known compatibility issues with the compress script in
v3?
Thanks for your help,
Dave

js -d
turn on debugging, then run
load('appname/scripts/compress.js')
The debugger will catch in a few Envjs feature detection errors, ignore those.

It should say which scripts its compressing at that time. If you see nothing try a very simple app (just the cookbook). If that works, then start adding in pieces again until you see what breaks it.

I tried js -d and ran the load command, and it breaks on a file called
date.js. I got it from here: http://www.datejs.com/
It's already compressed, perhaps that's the problem. It says the error
is on line 46, I believe this is the file I grabbed:
http://code.google.com/p/datejs/source/browse/trunk/build/date-en-US.js

What is the error? You can steal things with the compress: false flag.

Just to clarify, I uncompressed part of this date.js file, and found
the error to be happening in this code:
Date.prototype.getOrdinal=function(){
switch(this.getDate()){
case 1:
case 21:
case 31:
return"st";
case 2:
case 22:
return"nd";
case 3:
case 23:
return"rd";
default:
return"th";
}
};
the error to be happening in this code:
Date.prototype.getOrdinal=function(){
switch(this.getDate()){
case 1:
case 21:
case 31:
return"st";
case 2:
case 22:
return"nd";
case 3:
case 23:
return"rd";
default:
return"th";
}
};

This might be a problem w/ rhino. However, why is this code running? I'm pretty sure we prevent env from running load or ready event handlers.justin...@gmail.com

Yeah, I couldn't figure out why it's trying to run that code during
the compress process. I guess I'll live without compression for now.

I uncompressed everything in date.js, and the code that barfs is this
function:
// Tokenizers
//
rtoken: function (r) { // regex token
return function (s) {
var mx = s.match(r);
if (mx) {
return ([ mx[0], s.substring(mx[0].length) ]);
} else {
throw new $P.Exception(s);
}
};
},
On the line with the '} else {'. I have no idea why that's happening.

maybe the compressor doesn't recognize:
return ([ mx[0], s.substring(mx[0].length) ]);
did you try removing the parenthesis:
return [ mx[0], s.substring(mx[0].length) ];

It seems to occur in both the compressed and the uncompressed version,
so it probably isn't related to end of line characters. I tried
messing with it and it didn't seem to have any effect.

I'm not sure whether the problem is with compressor, rhino, or envjs.
How can I tell?
Here are the steps to reproduce my problem:
1. from command line run: js -d
2. inside Rhino interface, toggle Debug -> Break on Exceptions
3. type load('appname/scripts/compress.js') and hit Enter.
4. Click Go.
5. Watch a bunch of files open up in the Rhino interface
6. Rhino throws this Exception when it opens date.js:
Exception in Script
org.mozilla.javascript.EcmaError: TypeError: Cannot read
property "0" from undefined (file://path/to/appname/../appname/
resources/date.js#142)
Or, if I load the uncompressed version of date.js, which is comprised
of 5 separate files, it throws this exception:
Exception in Script
org.mozilla.javascript.JavaScriptException: [object Object]
(file://path/to/appname/../appname/resources/datejs/src/parser-
debug.js#26)
Is that enough information? I'm not sure beyond that what Rhino
JavaScript Debugger is doing at the point where it gets the error.
Thanks for your help,
Dave

Rhino -> JavaScript interpreter
Envjs -> Simulated Browser
Closure -> The compression engine.
It looks like it's a problem with the JS interpreter.
What happens if you just load the parser file?
load('parser-debug.js')

I commented out the offending line, and found a few other lines of
code that cause similar Exceptions:
line 383 of parser-debug.js:
var r = rule.call(this, s);
return [fn.call(this, r[0]), r[1]];
line 814 of parser-debug.js:
var _get = function (f) {
return _F[f] = (_F[f] || g.format(f)[0]);
};
When I get rid of that code, there are no more Exceptions thrown in
the debugger, but it still seems to hang on a file that contains this
text:
steal.end();
The title of this window in Rhino is eval(steal.end();...):
1278564059804
From there, the only button I have access to is "Break". Once I click
that, it takes me to line 5346 of env.js: for(;;) {

the DateJs extension to Date are in conflict with how Envjs uses Date.
One workaround is to wrap datejs code with this:
if (!navigator.userAgent.match(/Rhino/)) {
...
datejs code
...
}
this should allow you to compress the app.

How can you be sure about that?
How does Env use date? Date is part of ECMAScript, not the DOM.

When I do that I receive an error on line 412 of env.js:
org.mozilla.javascript.EvaluatorException: Compilation produced one syntax errors.
Then I hit OK, and Go, and I receive this error:
org.mozilla.javascript.EcmaError: TypeError: Cannot find function today in object function Date() { [native code for Date.Date, arity=1] } . (file://path/to/appname/../appname/models/week.js#22)
This line of code that errors out is trying to use code from date.js, which I suppose is excluded because of that if statement I added to date.js.

You might ask if people use datejs on rhino and if there is a supported version.

Just an update on this one, I actually removed date.js and reverted to default JavaScript date functionality throughout my jmvc app, and Rhino worked perfectly. I didn't get any feedback from the date.js team.
Datejs does seem like a great idea, but I think it's just a little half baked. Are there any other similar attempts to make it easier to work with dates in JavaScript? Do most people rely on jQuery UI Datepicker's stuff?
