I've been thinking a bit about writing a JSM for validating arguments coming into a function.
The first part would be the set of assertion functions: * a non-empty string * a whole number * a positive number * a non-negative number * a function * instanceof * typeof * member of a set * Custom validation function returning true or false * etc. The second part would be how to respond to an assertion failure: * Throw an Error * Throw Components.Exception * Report to JS console service * Report to a provided Log.jsm logger * Trigger a debugger keyword * Custom failure function * Ordered combinations of the above Above all else, the module should have a simple API. Something like this could be useful throughout the Mozilla codebase, and for addons or custom XULRunner applications. Suggestions? If there's an existing module out there, I'd like to hear of it before reinventing the wheel. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
