Lua reported a runtime error on Linux, Aegisub 3.2.2
Detail
Is anyone capable to fix it, i am willing to pay for that fix. Thank you

The file:
https://github.com/TypesettingTools/Aegisub/blob/master/automation/autoload/select-overlaps.moon
(in /usr/share/aegisub/automation/autoload/select-overlaps.moon)

ChatGPT suggested this modification:

Replace:
[prepare i, line for i, line in ipairs subs when is_dialogue line]

by:
[prepare i, line for i, line in ipairs(subs) when is_dialogue(line)]

or by:
[prepare(i, line) for i, line in ipairs(subs) when is_dialogue(line)]

saying:

"The issue in the provided Lua script is with the ipairs function being used on the subs object. The error message indicates that Lua is expecting a table but received a userdata instead."

But it does not work. Do you have please idea what to try? I am trying to detect and fix subtitle overlaps in several .ass files.

An issue of the luajit and the current Aegisub version?

This is an issue with Debian's Aegisub package. Aegisub needs luajit to be compiled with the Lua 5.2 compat flag, which Debian's luajit does not seem to have. This results in the __ipairs metatable entry on the subs object not being respected.

To fix this you would need to compile Aegisub yourself with --force-fallback-for=luajit.

Sorry for commenting after the bug was closed, but I'm the Debian Maintainer for Aegisub and I want to clarify this issue because I keep getting e-mails about this.
As I explained some years ago in Aegisub#141, the Debian version of luajit is not compiled with the Lua 5.2 compat flag, so it can't be used with Aegisub.
On the other hand, uploading a new package version to the current stable is not straightforward (see https://www.debian.org/doc/manuals/developers-reference/pkgs.html#upload-stable), so the changes I can make are minimal. What I can do is trying to build version 3.2.2 with Lua 5.2 and without luajit. If this works, I think that it could get into stable.
First I'll upload 3.4.0 to unstable (probably today or tomorrow) and then I'll try to update 3.2.2.

@aniolm9 I've opened #239 for discussion on the luajit 5.2 issue
