Linus Romer submitted an update to the

bezierplot

package.

Version: 1.5 License: lppl1.3c

Summary description: Approximate smooth function graphs with cubic bezier splines for use with TikZ or MetaPost

Announcement text: ----------------------------------------------------------------------

The Lua script bezierplot.lua has to work as a main with an external call from pdfLaTeX as well as a library with a direct use of the function bezierplot() when used with LuaLaTeX. However, Lua does not seem to support a natural distinction between the main and the library: https://stackoverflow.com/questions/4521085/main-function-in-lua. As https://www.tug.org/pipermail/luatex/2024-February/007935.html states, LuaTeX 1.18.0 has disabled the use of the debug library. Hence, using pcall(debug.getlocal, 4, 1) is no longer possible without restriction. The problem with the now chosen method is that arg could be defined as a global variable in the calling code.
