I had already installed Xavante. As I didn't know how Orbit works, I imagined it internally called Xavante. So I imagined an embeded server. This things are still confused for me. I found a brief tip

You need a web server. Just running the app doesn't work. You need to use apache2 (https://luanova.org/setting-orbit-to-use-apache2/) or Xavante (luarocks install wsapi-xavante). I highly recommend X

Coming back to Lua 5.1, the error disappear. But, I was not able to launch the script! It seems to be very close. No errors, but no results. Doing "$ lua app.lua" at the terminal, nothing is writen,

In the first, "xml" is local. In the second, xml is converted, just like every non-local symbol, to _ENV['xml'].  And you just set _ENV to be an empty table. Such is the magic of _ENV. As for the ri

I'm still curious about how closures are actually handled. Function parameters and function locals are not members of _ENV, I understand function parameters live on the stack and I assume space for f

The script below shows a difference of behaviour between LuaJIT and Lua 5.1.4 (or Lua 5.2.0 alpha). LuaJIT produces an error and it's a good behaviour (see with Mike Pall) At the first call, 'reader'

(I believe you meant "the largest, 1000") Actually, table.remove will call lua_objlen() to get the table size (1000 under my proposal), and will remove it immediately. Under my proposal, removing th

It allows for an efficient implementation of the # operator. What happens (I think) is that as positive indices are added to the table, Lua searches for any index where t[index] exists and t[index +

This is something I've brought up before (and seems to fit in with the current int vs float discussion as well). In a lot of cases it's easy and convenient to use Duck Typing in Lua. You don't check
