  • CTAN update: bezierplot

    From CTAN Announcements@21:1/5 to All on Sat Mar 23 08:40:53 2024
    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.

    In the last version, functions like "sqrt(x)*sin(x)/x" created
    an infinite loop. This was because the recursion added new
    inflection points as the derivative was calculated numerically.
    In this version, a maximum recursion depth stops the loop.

    Sinh, cosh, tanh, rad, deg have been added as function types.
