Update only firing every 2nd change

[josh18]

For some reason watchify only seems to be firing every second change. I assume this is something in my environment but I have no idea what it is that could be doing it.

Doesn't seem to matter how long there is in between saves it still will only run every second save. I closed all my applications except my text editor and terminal and it was still happening.

package.json

{
  "devDependencies": {
    "browserify": "^10.2.4",
    "reactify": "^1.0.0",
    "watchify": "^3.2.3"
  },
  "browserify": {
    "transform": ["reactify"]
  },
  "scripts": {
    "watch": "watchify src/test.js -o dist/test.js"
  }
}

test.js

var test = 1;

Details

System: OS X 10.7.5 (unfortunately)
Editor: Sublime Text 3 and also tried TextEdit

Let me know if you need any more information or you have any suggestions that I should try.

You should look through the issues. Have you tried using polling?

[josh18]

I've searched through the issues but can't find anything similar. Tried polling as well but same thing unfortunately.

Just tried on a different computer now and it works fine so definitely something with my environment. Is it possible that it is just OS X 10.7.5?

[zertosh]

that's kinda old. maybe? I have no way of testing. watchify uses chokidar as the watcher lib, maybe there is more info on older OS X versions there.

[josh18]

Hmmm just searched through the chokidar issues and can't find anything. I'll close this as it's definitely something with my environment.

I'll try a couple different things and report back if I manage to fix it. It's just weird that it requires two saves every time without exception. I can save it twice in a row and I can save it once and then wait 5 minutes and save it again and it will work but will never work on the first save.

Thanks for your help.

Ok I found what the issue was. The grandparent folder had an exclamation mark (!) at the start of it's name which was somehow messing it up. If the exclamation mark is in the middle it seems to be ok.

I'm assuming this is a bug with chokidar, do you think it's worth making an issue? (When I get a chance I also need to confirm that it's not just happening in OS X 10.7.5)

@josh18 It could be a problem with chokidar's anymatch. It might be interpreting it as a negation glob.
