Module.id in Windows Includes file extension (.js) Which Disrupts Directory Structure

[pnewhook]

I was trying to run

tusk.cmd help 

but i get the following error:

C:\Gited\280North\narwhal>tusk.cmd help
Usage: help [OPTIONS] COMMAND
A Narwhal project package manager.
require error: couldn't find "C:\Gited\280North\narwhal\lib\narwhal\tusk.js\list"

I looked at tusk.js and found

parser.command('list', module.id + '/list');

if i replace this with

parser.command('list', C:/Gited/280North/narwhal/lib/narwhal/tusk' + '/list');

The example works. Obviously you can't hard code the file path, but I couldn't find where module.id was set to override the windows behaviour.

I'm running Windows XP SP3

module.id ultimately gets set in lib/sandbox.js (look for module.id = id). I'm not sure how it's keeping the extension. It might be a bug in the module search algorithm, but more likely one of the file system routines. Would you be able to isolate this?

[pnewhook]

I'd like to try to isolate this but I'm not sure where to start. IN sandbox.js i don't see module.id=id. the closest thig i have is

if !Object.prototype.hasOwnProperty.call(modules, id) || reload)
            modules[id] = {};

one line 228 or

        var module = {
            'id': id,
            'path': factory.path
        };

on line 246.

How would you recommend isolating it? Is this something the Rhino debugger may help with?

[kriskowal]

Yeah, the Rhino debugger will give you a stack trace; you can put probes (hahah, euphemism for print(data)) into all the active functions and evaluate whether they're doing what they're supposed to, namely, not putting .js in the module identifier.

[pnewhook]

I dropped this into sandbox.js

        var module = {
            'id': id,
            'path': factory.path
        };
        print(module.id);
        factory(require, exports, module, subsystem, subprint);

And this is what I got on the Rhino console:

global
array
object
string
regexp
date
binary
binary-engine
function
json
system
io
io-engine
file
file-bootstrap
file-engine
os
os-engine
logger
narwhal
args
util
term
packages
packages-engine
C:\Gited\narwhal\lib\narwhal\tusk.js
http
http-engine
Usage: help [OPTIONS] COMMAND
A Narwhal project package manager.

so something is definitely wrong with the way the Tusk module is loaded. What's your recommendation to look into this?

[kriskowal]

Oh! This is very helpful. It seems that the narwhal/tusk module is
being loaded as a script instead of as a module, which is very
possible depending on the tusk shell script. I'll look into this.

[kriskowal]

Please let me know if this fixes the problem:

I tried your fix and I think it may have worked, but I can't tell 100% because there appears to be another problem. I tried both applying your patch to the 280 North fork and your repository and got the same results. I ran tusk.cmd help still with that line in sandbox.js to print module.id and got this
C:\Gited\narwhal>tusk.cmd help
global
array
object
string
regexp
date
binary
binary-engine
function
json
system
io
io-engine
file
file-bootstrap
file-engine
os
os-engine
logger
narwhal
args
util
term
packages
packages-engine
narwhal\tusk
http
http-engine

so it looks like it's finding tusk properly. I ran this again in the debugger and the application just stalled at http-engine.js

function(require,exports,module,system,print){
var IO = require('./io').IO;

exports.IO = function (url) {
return new IO(
new java.net.URL(url).openStream(),
null
);
};

// */
}

I tried commenting out the require(http) like in tusk.js but then it stalls at narwhal/tusk

Should I close this ticket and open a new one or is this related?

ps Thanks for all your help.
