Re: [NTG-context] how to hyphenate SHA512?

8 Jul 2017

      If I am not mistaken SHA is only hexadecimal digits, so you probably need only to have a « language » that hyphenates between any pair of those. Should be much simpler I guess, but I do not really know how to add such setting I am afraid.

Many thanks for your reply, Joseph.

The underscore I want to use should be placed below the previous
character, such as in (code from Hans):

    \startluacode

        function document.addfunnyhyphen(tfmdata)
            local underscore = utf.byte("_")
            local char       = tfmdata.characters[underscore]
            if not char then return end
            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
        [underscore]
        [righthyphenchar="FE000]

    \setuphyphenation
        [method=traditional]

    \sethyphenationfeatures
        [underscore]
    \starttext
    \hsize\zeropoint

    hyphenation
    \stoptext

Is there no way to define a language that hyphenates any pair of characters?

Many thanks for your help,

Pablo

A probably quick and dirty « solution », which consists in inserting a

Dear list,
I have the following sample:
\starttext
    \hsize\zeropoint
    hyphenation
8b2f3c087046c3943ace0dc4f958ef2138e58a51b40eef6fab6fa1aeb845cc25%
    7a410ab1b914bc399b4293f31c76fc2c73e5be5ea4d329f9e6820984688efec2
    \stoptext
I plan to use underscore hyphenation. How can I get the SHA512 string
hyphenated in any of its points?
Many thanks for your help,
Pablo
