underscore hyphenation in LMTX

underscore hyphenation in LMTX

[Pablo Rodriguez]

Dear list,

I have the following sample:

    \startluacode
    function document.addfunnyhyphen(tfmdata)
        local underscore = utf.byte("_")
        local char       = tfmdata.characters[underscore]
        tfmdata.characters[0xFE000]   = {
            width    = 0,
            height   = 0,
            depth    = 0,
            commands = {
                { "right", -char.width },
                { "down", char.depth },
                { "slot", 1, underscore },
            }
        }
    end

    utilities.sequencers.appendaction("aftercopyingcharacters","after",
        "document.addfunnyhyphen")
    \stopluacode

    \definehyphenationfeatures
          [whatever]
          [righthyphenchar="FE000]

    \setuphyphenation[method=traditional]
    \sethyphenationfeatures[strict, whatever]

    \setuppapersize[A10, lanscape]

    \starttext
        \startmakeup[standard]
        \hsize\zeropoint
        \tt definebodyfont
        \stopmakeup
    \stoptext

I get the underscore hyphenation with latest ConTeXt beta (LuaTeX-1.10),
but not with latest LMTX (LuaTeX-2.0).

Am I missing something here?

Many thanks for your help,

Pablo

use slot '0' instead of '1' (i'll catch it anyway)
