Folks,
being a complete newbie who wants to experiment a little with LuaTeX, I ask for some help to improve `texinfo.tex` for generating the documentation of LilyPond. Within the `@code` macro, I want to do two things. (a) Hook into the `hyphenate` callback to insert hyphenation discretionaries based on some constraints. (b) Hook into `pre_linebreak_filter` (or rather `contribute_filter`?) to inhibit line breaks before/after a single character if preceded/followed by a (single) space. In other words, this space should be replaced with `@tie{}`. How can I do that? I guess I have to do the following. (1) Write hooks `code_hyphenate` and `code_pre_linebreak_filter`. (2) At the beginning of `@code`, append the `code_hyphenate` hook. (3) At the end of `@code`, remove the `code_hyphenate` hook. Assuming this is the correct approach I have some questions. * It's not written explicitly in the LuaTeX manual but I guess that the argument to the `hyphenate` hook is a single word. * I couldn't find information in the manual about the order of hooks. It seems that I have to save the original hook by myself and call it before/after, right? * Is there already some code available that I could use as a starting point? Werner
