The version up for Download is broken

[matthewrobertson]

I'm a bit of noob to Lawnchair but it seems to me that the version available for download on:

http://westcoastlogic.com/lawnchair/downloads/

is broken.

Specifically after instantiating a new Lawnchair it has no exists() method. This leads to various other bugs.

I noticed this is the case for both the compressed and uncompressed version.

On further inspection it seems like this code:

Lawnchair.adapter = function (id, obj) {
    // add the adapter id to the adapter obj
    // ugly here for a  cleaner dsl for implementing adapters
    obj['adapter'] = id
    // methods required to implement a lawnchair adapter 
    var implementing = 'adapter valid init keys save batch get exists all remove nuke'.split(' ')
    ,   indexOf = this.prototype.indexOf
    // mix in the adapter   
    for (var i in obj) {
        if (indexOf(implementing, i) === -1) throw 'Invalid adapter! Nonstandard method: ' + i
    }
    // if we made it this far the adapter interface is valid 
    Lawnchair.adapters.push(obj)
}

checks that the adaptor has no extra interface methods but it does not, check if is missing anything. I will write a test for this later and submit a pull request if it turns out to be true...

EDIT:

Actually I have tested this and it does seem to check if methods are missing so disregard this post (but the issue of the version up for download being broken is still valid as far as I can tell)

Actually there is an "exists()" method in the "dom" and "window-name" adapters, but it looks like the current version of the "indexed-db" one is missing it [another bug to add here].
which adapter are you using? only the default ones?
as reported in #83 , the downloadable version on the website is an old version, so check out the source on github instead.

Yep, I was using the db adapter.

I ended up checking out the master code and everything has been working fine since. I think not having an up to date version up for download is a bigger issue. If you want I can probably package up the master HEAD and submit a pull request to your gh-page branch.
