man.vim: Recognise hyphenated-at-eol cross-references (#12609) Commit: https://github.com/vim/vim/commit/8cfe52e6fbf44032cd40d1561e93644786b15ee7 Author: goweol <goweol@gmail.com> Date: Fri Aug 18 06:13:29 2023 +0900 man.vim: Recognise hyphenated-at-eol cross-references (https://github.com/vim/vim/issues/12609) Manual pages requested for output may undergo formatting arranged by some roff-descendant program. Lines longer than MANWIDTH or COLUMNS or real-estate width of a device (with support for horizontal scrolling considered) can be divided at either blank characters and/or at groups of word characters (syllables) according to supported hyphenation rules (although page authors are free to disable hyphenation or prevent particular words from being hyphenated). Groff?s manual describes it as follows: 5.1.2 Hyphenation Since the odds are not great for finding a set of words, for every output line, which fit nicely on a line without inserting excessive amounts of space between words, gtroff hyphenates words so that it can justify lines without inserting too much space between words. It uses an internal hyphenation algorithm (a simplified version of the algorithm used within TeX) to indicate which words can be hyphenated and how to do so. When a word is hyphenated, the first part of the word is added to the current filled line being output (with an attached hyphen), and the other portion is added to the next line to be filled. It would be expedient for autoload/dist/man.vim (along with syntax/man.vim?s highlighting and ftplugin/man.vim?s Ctrl-], \K mappings) to allow for hyphenation of cross-references to manual pages. For example, # Launch Vim [v9.0; patched: 1-1378, 1499] as follows: MANWIDTH=80 vim --not-a-term +MANPAGER '+Man man' '+/conv(1)' '+norm B' # Press Ctrl-] with cursor on _m_: "... use man? # conv(1) directly."_______________________[^] # # (Man v2.11.2) # Launch Vim as follows: MANWIDTH=80 vim --not-a-term +MANPAGER '+Man git' '+/config(1)' '+norm B' # Press Ctrl-] with cursor on _g_: "... in git- # config(1) for a more ..."_______________[^] # # (Git v2.39.2) Co-authored-by: Aliaksei Budavei <0x000c70@gmail.com>
