On this page of the wiki there is an example for wrapping long words,
like long hexadecimal strings:
https://wiki.contextgarden.net/Wrapping
This example is buggy because it deletes one character at the point that
it is wrapped.
Anyone have a solution?
Many thanks for your report, Hugo.
I use this code from time to time and I totally overlooked this.
Have you checked all options that the sample contains?
Hans,
I have just checked that these line breakings loose a character in all
options.
The next sample displays the issue clearly:
\startluacode
--local shared = {
-- start = 1,
-- length = 1,
-- left = false,
-- right = false,
--}
local shared = {
start = 1,
length = 1,
before = utf.char(0xB7),
after = nil,
left = false,
right = false,
}
-- languages.hyphenators.traditional.installmethod("sha",
-- function(dictionary,word,n)
-- local t = { }
-- for i=1,#word do
-- t[i] = shared
-- end
-- return t
-- end
-- )
-- or more efficient when used often:
-- local all = { }
-- for i=1,512 do
-- all[i] = shared
-- end
-- languages.hyphenators.traditional.installmethod("sha",
-- function(dictionary,word,n)
-- return all
-- end
-- )
-- or more obscure:
-- local all = table.setmetatableindex({ }, function(t,k)
-- t[k] = shared
-- return shared
-- end)
--
-- languages.hyphenators.traditional.installmethod("sha",
-- function(dictionary,word,n)
-- return all
-- end
-- )
-- or just (lua is fast enough anyway)
local all = table.setmetatableindex({ }, function(t,k)
return shared
end)
languages.hyphenators.traditional.installmethod("sha",
function(dictionary,word,n)
return all
end
)
\stopluacode
\definehyphenationfeatures
[sha]
[characters=all,
alternative=sha]
\unexpanded\def\sha#1%

Are we missing something or is this a bug?
what do you expect as result? (maybe try \righthyphenmin=1)
