From 59baa5e8a1f9e71b82f28c2723ccc558370b6fc0 Mon Sep 17 00:00:00 2001 From: Riley Bruins Date: Thu, 29 Aug 2024 09:36:33 -0700 Subject: fix(tohtml): apply sp color if present #30110 Problem: Things like underlines are always given a default foreground highlight regardless of the value of `sp`. Solution: Check for `sp` first, and apply that color to the text decoration color if it exists. Limitations: If there is no value of `sp`, vim applies a text decoration color that matches the foreground of the text. This is still not implemented (and seems like a much more complex problem): in TOhtml, the underline will still be given a default foreground highlight. --- runtime/lua/tohtml.lua | 3 +++ 1 file changed, 3 insertions(+) (limited to 'runtime/lua/tohtml.lua') diff --git a/runtime/lua/tohtml.lua b/runtime/lua/tohtml.lua index a4b5a741bc..6a5bd6de9d 100644 --- a/runtime/lua/tohtml.lua +++ b/runtime/lua/tohtml.lua @@ -1003,6 +1003,7 @@ local function extend_style(out, state) --TODO(altermo) use local namespace (instead of global 0) local fg = vim.fn.synIDattr(hlid, 'fg#') local bg = vim.fn.synIDattr(hlid, 'bg#') + local sp = vim.fn.synIDattr(hlid, 'sp#') local decor_line = {} if vim.fn.synIDattr(hlid, 'underline') ~= '' then table.insert(decor_line, 'underline') @@ -1020,6 +1021,8 @@ local function extend_style(out, state) ['font-weight'] = vim.fn.synIDattr(hlid, 'bold') ~= '' and 'bold' or nil, ['text-decoration-line'] = not vim.tbl_isempty(decor_line) and table.concat(decor_line, ' ') or nil, + -- TODO(ribru17): fallback to displayed text color if sp not set + ['text-decoration-color'] = sp ~= '' and cterm_to_hex(sp) or nil, --TODO(altermo) if strikethrough and undercurl then the strikethrough becomes wavy ['text-decoration-style'] = vim.fn.synIDattr(hlid, 'undercurl') ~= '' and 'wavy' or nil, } -- cgit
