I have pull requests (minivan/middleman-spellcheck#25 & minivan/middleman-spellcheck#23) in for the changes to middleman-spellcheck. When the changes are merged I will make a pull request to update the gemfile here.

Maybe we should put in something about Linux and Windows?

During build, Middleman will require Aspell to look for misspellings. On Macs, it can be installed via Homebrew:

brew install aspell --with-lang-en

On Windows, you can download an installer, but unfortunately it is unmaintained. On Linux, you can install with your distribution's package manager. On all platforms, you can also build the most recent version from source.

Good point. I will add some instructions to the README for Linux and Windows.

This looks great, @mwils! Thanks for your work.

One other thing - there are some words in the exceptions list that look a bit strange to me, like actionhttp and allget. I couldn't find these words in the rest of the project.

Welcome.
I think the spellchecker is throwing together some words that are only separated by a tag. I will fix the bug and remove the words from the list.
It may be a bit before I can look at it. Should I amend the changes to this commit or make a new commit?

[michaelrkn]

Why don't you just update the README, and then come back to fixing the spellchecker when you have time?

[mwils]

Will do

[mwils]

Updated the README.

[michaelrkn]

Thanks! Can you just add jQuery's so that the build will pass now? :)
