Many thanks for your sample, Hans.
It really works great.
Sorry for asking this again: would it be possible to add this feature also to \hyphenatedurl.
I’m composing a book on A6 and it is really hard to add some urls.
some code from an upcoming manual: \startluacode local specials = { ["!"] = "before", ["?"] = "before", ['"'] = "before", ["'"] = "before", ["/"] = "before", ["\\"] = "before", ["#"] = "before", ["$"] = "before", ["%"] = "before", ["&"] = "before", ["*"] = "before", ["+"] = "before", ["-"] = "before", [","] = "before", ["."] = "before", [":"] = "before", [";"] = "before", ["<"] = "before", [">"] = "before", ["="] = "before", ["@"] = "before", ["("] = "before", ["["] = "before", ["{"] = "before", ["^"] = "before", ["_"] = "before", ["`"] = "before", ["|"] = "before", ["~"] = "before", -- [")"] = "after", ["]"] = "after", ["}"] = "after", } languages.hyphenators.traditional.installmethod("url", function(dictionary,word,n) local t = { } for i=1,#word do local w = word[i] local s = specials[w] if s == "after" then s = { start = 1, length = 1, after = w, left = false, right = false, } specials[w] = s elseif s == "before" then s = { start = 1, length = 1, before = w, left = false, -- right = false, } specials[w] = s end t[i] = s or false end return t end ) \stopluacode \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 [url] [characters=all, righthyphenchar="FE000, alternative=url] \setuphyphenation[method=traditional] \unexpanded\def\hyphenatedurl#1% {\dontleavehmode \begingroup \tt \sethyphenationfeatures[url]% #1% \endgroup} \starttext \hsize5mm \hyphenatedurl{http://www.pragma-ade.nl} \stoptext
Many thanks for your help again,

we can add some of them but first i need to think about what slots to use (shouldn't conflict with other private slots)
