Looks like the latest commits have not actually been pushed?

it looks like the issue we reported with _PROMPT is missing from the list.

Now it is:

thanks!

for the record, the related:

> setmetatable(_G, {__index=function(t, k) if k == "_PROMPT" then
error({}) end end})

reproduces as far back as (at least) lua 5.2.4

sorry, we meant to say 5.3.6 >.<

G'day,

I'm pleased to report that I've tried the latest -rc4 in my "lglicua"
test rig (set of virtual machines), and the results are very pleasing.
I've noticed some glitches with very new releases, but these are
unrelated to Lua and/or LuaRocks. (e.g. webkit2-gtk-4.1 has arrived,
but I think that tecmake.mak assumes webkit2gtk-4.0... not sure).

For the record, everything worked with Lua 5.4.7-rc4 for:

Ubuntu-based:

Linux Mint 21.3:
- Kernel 5.15.0-112-generic
- gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0


MX Linux 23.2_ahs_x64:
- Kernel 6.8.12-1-liquorix-amd64
- gcc (Debian 12.2.0-14) 12.2.0

Ubuntu 22.04.4:
- Kernel 6.5.0-28-generic
- gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0


Ubuntu 23.10:
- Kernel 6.5.0-35-generic
- gcc (Ubuntu 13.2.0-4ubuntu3) 13.2.0


Red Hat-based:

CentOS-7:
- Kernel 3.10.0-1160.118.1.el7.x86_64
- gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44)

Rocky Linux 9.3:
- Kernel 5.14.0-427.18.1.el9_4.x86_64
- gcc (GCC) 11.4.1 20231218 (Red Hat 11.4.1-3)

The test produced some "Hello world" modal dialog boxes (from a
2-line script), a PDF with graphics from a Lua script, and a
trivial "test.pptx" output (pdf and pptx from Canvas Draw).

-------

Just to clarify, the existing "lglicua" release, 0.1-beta1, has
a number of changes, and is brittle under 5.4 (even before
-rc3 was released). I have -beta2 in the pipeline, and all the
Lua+LuaRocks testing has been done with a "near-0.1-beta2"
version.

--------

Thank-you so much to everybody who is working on (or who has
worked on) Lua, LuaRocks, the many individual Rocks themselves,
and the Tecgraf scientific/technical+graphical toolkit
components IM, CD and IUP.

cheers,

In fact, 5.3.0 already had it.

Lua 5.4.7 (rc4) is available for testing at
https://www.lua.org/work/
Please try it before we freeze it.

If there is no further feedback on Lua 5.4.7, we'll freeze it next week, and it will become the current release of Lua 5.4.

I've updated Lunatik and it's working just fine =). I took the
opportunity and added a (very coarsed) guide [1] to document the
"git-fu" I'm doing to keep track of upstream changes. I welcome any
other fork maintainer who has the same constraints (e.g., no floating
point, no OS) to join efforts and unify the forks. Feel free to reach
out to me directly.
