Lua 5.5 and LuaRocks...

G'day,

Not surprisingly, some Rocks are not compatible with Lua 5.5.  I don't
know if there's a program to decide yes/no/maybe on support for
individual rocks.

The list I see is from my habitual use, which closely coincides with
the lglicua package.

The disruption I see is:

        - std.normalise [no results matching...]

        - std.strict    [no results matching...]

        - luaposix      [dependency luabitop >= 1.0.2 fails...]

        - bit32         [no results matching...]

---------------------

Part of the problem is that I've adopted a Lua-5.4-standard preamble,
which strives to allow me to switch between Lua-5.[1234] versions
quite easily, as long as I stay within a conservative subset of the
language features.

>        local strict = require("std.strict")
>        _ENV = strict.strict(_ENV)

>                setfenv(1, _ENV)
>        end

I recognise that the new global/local scoping mechanism, added as part
of Lua 5.5, affects things like std.strict.

---------------------

I require at least luaposix [needs luabitop >= 1.0.2] in order to work.
This is because I try to take a very, very restrictive stance in dealing
with shells and command invocation, trying to avoid "shell-special"
characters that might provide an opportunity for a malicious user to
manipulate a shell into performing unwanted actions.

I've been in contact with Hisham over the last couple of months, and he
has been helpful.  However, I don't know the best protocol for dealing
with the entire database of Rocks supported by LuaRocks.

Thanks for reading this far!
