彩色法式装饰的妙用

Question

我将此字体文件保存为示例：

-- file pagella.lfg
return {
    name = "pagella",
    comment = "Goodies that complement pagella.",
    colorschemes = {
        default = {
            [1] = {
                0x0301, 0x0300, 0x0302, 0x0308, 0x0323,
            },
        },
    },
}

获得彩色的强调。

但我没有结果。缺少什么？

\input pagella.lfg
\mainlanguage[fr]
\setupcolors[state=start]
\definefontfeature
  [pagella]
  [goodies=pagella,
   colorscheme=default,
  ,protrusion=quality,expansion=quality] 
\definecolor[colorscheme:1:1][r=1,g=0.3]

您需要做的有点棘手，因为 ConTeXt 处理的是预组合字符。解决方案是手动将重音字符拆分为非重音字符，然后组合变音符号（Unicode 范围 0300–036F）。以下是您可以在 ConTeXt 中定义的其他类型的特征的列表.然后你对标记进行颜色组合以获得所需的效果。

顺便说一句，我刚刚考虑了一些小写字母的随机示例。您可以自行扩展要转换的字符列表。

注意事项：关于i：当包含此字母的大小写时，请改用无点形式ı(U+0131)。否则，您的变音符号将被错误放置。另外，我没有包含，i因为它会弄乱连字，如fi和ffi，但没有什么可以阻止您这样做（但请不要这样做）。

--Save this in the same folder as your main file
--coloredaccents.lfg
return {
    name = "coloredaccents",
    version = "2021/02/09",
    comment = "Colored accents for French",
    author  = "Jairo A. del Rio",
    colorschemes = {
        default = {
            { "0x0300:0x036F" }, -- Combining Diacritical Marks
        }
    }
}
