Detect when FOAM is already installed #202

Open mdittmer opened 7 years ago

mdittmer commented 7 years ago

Use case: Browser extension that injects script into pages. Some pages may have FOAM installed.

Problem statement: Attempting to install FOAM twice results in obtuse errors (e.g., attempting to reinstall Object.prototype.$UID). It would be nice if FOAM could detect that it was already installed, and not bother installing itself.

Complicating factors: Of course, different versions of FOAM may be already installed / wanting to be installed. It's not clear what the best way is to deal with this. Perhaps implement some kind of versioning, let the first installed win, and emit a warning that different versions of FOAM were trying to install over top of each other.

Maybe we could install multiple versions of FOAM at once in different scopes or contexts, possibly using Javascript's 'with' statement.

Fully contextializing FOAM could be interesting.

It would make a "Develop FOAM2.1 in FOAM2" type situation feasible without even having to reload the page.
