[Windows] Error: watch ENOENT

[gadicc]

And maybe others :) Would love some help from Windows users. Otherwise will setup a Windows VM and look into this when I have a chance.

I have this error by just adding your package to mantra-sample-blog-app :

I'm using

gadicc:ecmascript-hot@1.3.2-refactor.6
gadicc:hot@0.0.21
gadicc:hot-build@0.0.8

It seems like this is undefined :

// meteor-hmr/accelerator/src/accelerator.js:15

const meteorToolPath = process.argv[4];

[gadicc]

@Vincent-P I'll address this in #56.

[Vincent-P]

The issue is with toDosPath function in hot-build/hot-server.js.

[Vincent-P]

There :

Hot.prototype.processFilesForTarget = function(inputFiles) {
...
      file = convertToOSPath(path.join(
        inputFile._resourceSlot.packageSourceBatch.sourceRoot,
        inputFile.getPathInPackage()
      ));
 ...
}

In Windows I have this :

// /E/Code/WEB/mantra-sample-blog-app
inputFile._resourceSlot.packageSourceBatch.sourceRoot

// lib/collections.js
inputFile.getPathInPackage()

// \E\Code\WEB\mantra-sample-blog-app\lib\collections.js
path.join(inputFile._resourceSlot.packageSourceBatch.sourceRoot, inputFile.getPathInPackage())

or
///E/Code/WEB/mantra-sample-blog-app/lib/collections.js
inputFile._resourceSlot.packageSourceBatch.sourceRoot + '/' + inputFile.getPathInPackage()

So path.join() replaces / with \ but toDosPath expects a / :

if (p[0] === '/' && ! partialPath) {
    if (! /^\/[A-Za-z](\/|$)/.test(p))
      throw new Error("Surprising path: " + p);
    // transform a previously windows path back
    // "/C/something" to "c:/something"
    p = p[1] + ":" + p.slice(2);
  }

So replacing path.join by a string concatenation works,

file = convertToOSPath(path.join(
    inputFile._resourceSlot.packageSourceBatch.sourceRoot,
    inputFile.getPathInPackage()
));

// to
file = convertToOSPath(inputFile._resourceSlot.packageSourceBatch.sourceRoot + '/' + inputFile.getPathInPackage());

[gadicc]

oh wow, amazingly helpful! thanks!!

[Vincent-P]

So now it seems to work on Windows, the app can start but I still have no idea on how to use this with Mantra.

I have replaced ecmascript, installed react-hot-loader and redbox-react, add "react-hot-loader/babel" to .babelrc but I dont know where I have to add the AppContainer...

[gadicc]

Mmm let me actually make a quick repo of mantra-sample-blog-app, I think a lot of people would benefit from it.

[gadicc]

Sorry I said quickly but I ran out of time and will only get to this tomorrow. I guess you'd put the AppContainer where you have the mount commands, possibly multiple times for each route action, I haven't actually looked yet how RHLv3 plays with mantra, but if you don't get it working I'll have a repo up tomorrow (I'm in GMT+2).

[Vincent-P]

Okay I'll try thank you.

[gadicc]

@Vincent-P, check out #60.

Unfortunately it's not so neat... the Mantra design isn't so compatible with react-hot-loader. Maybe we can find a compromise in the future.
