Hi Rik,
Thanks for the fast reply! Your example works indeed nicely. However, within
this solution my problem has shifted now (fully) towards breaking after the
same number of characters, which seems to work for your sample string, but not
for the sequences that I need to place.
What I would like to achieve is something like:
5’-GATTGCTTACTCCTGGTTGG
TGGGGCTTACATTCTGTCGCCTC
AAAACTACTAGAGCCGGCATATT
CTAGAAGGGCCGCCTTCATGTGG
etc.
(There might be hyphens or not, this is not so much important to me.)
But what I get is currently:
5'-GATTGCTTACTCCTG-
GTTGGTGGGGCTTACATTCT-
GTCGCCTCAAAACTACTA-
GAGCCGGCATATTCTA-
GAAGGGCCGCCTTCATGTGGC-
etc.
Which looks ragged with \tt. Certainly, this is because ConTeXt applies the
default hyphenation pattern. But I guess, there might be no “no language”
pattern or is there? Also, I agree, it’s a bit odd that nright/nleft seem to
make no difference towards the result.
Hans posted a solution for a similar problem a few years ago [1]
which can be adapted to your problem.
\startluacode
local shared = {
start = 1,
length = 1,
before = nil,
after = nil,
left = false,
right = false,
}
local all = table.setmetatableindex({ }, function(t,k)
return shared
end)
languages.hyphenators.traditional.installmethod("dna",
function(dictionary,word,n)
return all
end
)
\stopluacode
\definehyphenationfeatures
[dna]
[characters=all,
alternative=dna]
\starttext
\startframedtext[width=6cm,style=mono]
\sethyphenationfeatures[dna]
\setuphyphenation[method=traditional]
GATTGCTTACTCCTGGTTGG%
TGGGGCTTACATTCTGTCGCCTC%
AAAACTACTAGAGCCGGCATATT%
CTAGAAGGGCCGCCTTCATGTGG%
\stopframedtext
