This doesn't let you arbitrarily call back into the VM from within
foreign methods. I'm still not sure if that's even a good idea since
God knows what that would mean if you switch fibers while doing that.
But this does allow the very important use case of being able to call
a foreign method from within a call to wrenCall(). In other words,
foreign methods need to always be leaf calls on the call stack, but the
root of that stack can now come from runInterpreter() or wrenCall().
Fix#510.
- quick clean up pass on layout and colors for clarity/legibility
- added logo to the sidebar
- fix various css things like a full height page when content is shorter, so the footer doesn't creep away from the bottom
- start using em instead of px for consistency across devices
- copies files in doc/site/static/ to output
- update output formatting to include potential differences in markdown generator (local generate had >, so cover both to remain consistent)
- copy rss xml (could be in static too, but for now...)
When parsing the string token if a `\` was used it would
unconditionally consume the next character. This would led to a token
with an invalid lenght causing a crash when it was printed. This fixes
that by only consuming the token after the `\` if there is one to
consume.
Fixes#603
The VM used to not detect this case. It meant you could get into a
situation where another fiber's caller had completed. Then, when it
tried to resume that fiber, the VM would crash because there was nothing
to resume to.
This is part of thinking through all the cases around re-entrancy. Added
some notes for that too.
There's a lot of changes here and surely some rough edges to iron out.
Also, I need to update the docs. But I want to get closer to landing
this so I can build on it.
