What is the significance of "/*global $tw: false*/"?

[Ben H.]

I see this everywhere in the source code, and I can't figure out what it means. I'm confused because it is in a comment, so it isn't executable javascript code... What is it for?

Hi Ben

It's a pragma for configuring JSHint and compatible code checking tools. It tells JSHint not to treat $tw as an undefined variable (it is defined in all TiddlyWiki code modules courtesy of the module loader in boot.js). See the "Directives" section here:

http://jshint.com/docs/

At a quick glance, I notice that the docs have "globals" instead of "global"; I believe that TW5 is using an older but still supported keyword.

Best wishes

Jeremy.
