From 754892e59dc3ab65a92d22f315e88b716bc26d1d Mon Sep 17 00:00:00 2001 From: zeertzjq Date: Sat, 13 Aug 2022 11:29:38 +0800 Subject: vim-patch:8.2.{1536,1540}: charclass() (#19748) vim-patch:8.2.1536: cannot get the class of a character; emoji widths are wrong Problem: Cannot get the class of a character; emoji widths are wrong in some environments. Solution: Add charclass(). Update some emoji widths. Add script to check emoji widths. https://github.com/vim/vim/commit/4e4473c927167fd24e5c8df90e0e8035080cf2da Use latest charclass() docs from Vim. Rewrite DoIt() in emoji_list.vim in Lua. Omit emoji table updates: - emoji_width update looks wrong as these added ranges are only double-width when followed by 0xFE0F. - Other updates are too old. vim-patch:8.2.1540: the user cannot try out emoji character widths Problem: The user cannot try out emoji character widths. Solution: Move the emoji script to the runtime/tools directory. https://github.com/vim/vim/commit/98945560c1ae6e2ddee820a7de718a36e3f4b6e5 --- runtime/tools/emoji_list.vim | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 runtime/tools/emoji_list.vim (limited to 'runtime/tools') diff --git a/runtime/tools/emoji_list.vim b/runtime/tools/emoji_list.vim new file mode 100644 index 0000000000..c335b8c88f --- /dev/null +++ b/runtime/tools/emoji_list.vim @@ -0,0 +1,21 @@ +" Script to fill the window with emoji characters, one per line. +" Source this script: :source % + +if &modified + new +else + enew +endif + +lua << EOF + local lnum = 1 + for c = 0x100, 0x1ffff do + local cs = vim.fn.nr2char(c) + if vim.fn.charclass(cs) == 3 then + vim.fn.setline(lnum, '|' .. cs ..
