Output of awesome --version:

 • Compiled against Lua 5.2.3 (running with Lua 5.2)
 • D-Bus support: ✔
 • execinfo support: ✔
 • RandR 1.5 support: ✔
 • LGI version: 0.7.2

How to reproduce the issue:
Start awesome and press super + p

Actual result:

I'd like to see the menu ;-)

I'm running NixOS and this problem occoured with an update from v3.5 to v4.0.

Somewhere there is a nother bug report about menubar initialisation, but I cannot find it right now.
Could you apply the following diff and grab its output? So far I have no idea.

I experience the same issue. On the first invocation of Mod4 + p I see

share/awesome/lib/menubar/utils.lua:289: attempt to index field 'Async' (a nil value)

All subsequent invocations yield

share/awesome/lib/menubar/init.lua:199: attempt to index field 'prompt' (a nil value)

I'll try applying the patch now.

@rasendubi What's you LGI version? lua -e 'print(require("lgi.version"))'

[psychon]

NixOS has an ancient version of LGI: https://github.com/NixOS/nixpkgs/blob/98a9d815e05dd56aba0f9040d96092335cd90444/pkgs/top-level/lua-packages.nix#L385 (It's 0.7.2 and it is from 2013)

Turns out that menubar needs at least version 0.8.0 (from 2014, so also quite old) since commit 4eb8085.

Edit: I propose "fixing" this by increasing our minimum lgi version from 0.7.1 to 0.8.0 and to make menubar's initialisation more robust.

[rasendubi]

I'll update LGI now and report back.

[rasendubi]

Updated LGI to 0.9.1 and I don't see an error now.

[rasendubi]

Opened: NixOS/nixpkgs#21580

[flosse]

Updated LGI to 0.9.1 and I don't see an error now.

Works for me too :)
Thanks a lot!

[psychon]

We still have to do something on our side for this, like bumping the code that checks for too-old-lgi. :-)
