A probably quick and dirty « solution », which consists in inserting a \discretionary node between each digit using some lua code. There are mostly likely better solutions for this. Joseph \startluacode function sha(s) local out = {} for i = 1, s:len() do out[#out + 1] = s:sub(i, i) end context(table.concat(out, '\\discretionary{_}{}{}')) end \stopluacode \starttext % \hsize\zeropoint \hyphenation %%8b2f3c087046c3943ace0dc4f958ef2138e58a51b40eef6fab6fa1aeb845cc25% %%7a410ab1b914bc399b4293f31c76fc2c73e5be5ea4d329f9e6820984688efec2 \ctxlua{sha([[8b2f3c087046c3943ace0dc4f958ef2138e58a51b40eef6fab6fa1aeb845cc257a410ab1b914bc399b4293f31c76fc2c73e5be5ea4d329f9e6820984688efec2]])} \stoptext De : Pablo Rodriguez Envoyé le :jeudi 6 juillet 2017 12:00 À : mailing list for ConTeXt users Objet :[NTG-context] how to hyphenate SHA512? 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?
