Multi-version index reference manual

[François Perrad <francois.perrad@...>]

Now, there are many Lua versions and it is not easy to compare their reference manuals.

I aggregate the index of each version (5.1 -> 5.4) in one multi-version index.

I think this kind of resource could be useful on lua.org, near the actual reference manuals.

In attachment, the script used, but not the generated HTML which is detected as spam.

Anyway, it is available on https://fperrad.frama.io/lua-Harness/index/mindex.html
