问题描述
限时送ChatGPT账号..我想隐藏名称基于希腊符号的变量并将它们转换为它们的 Unicode 等效符号，类似于 vim-cute-python 有效.例如，我有这个:
I want to conceal variables with names based on Greek symbols and turn them into their Unicode equivalent symbol, similarly to how vim-cute-python works. For instance, I have this:
syntax match scalaNiceKeyword "alpha" conceal cchar=α
定义在一个文件中，用于隐藏在 Scala 文件中，效果很好，只是过于激进.如果我写alphabet，它就会被隐藏起来成为αbet，这显然是错误的.
defined in a file for concealing within Scala files which works great except that it's overly aggressive. If I write alphabet it then gets concealed to become αbet, which is noticeably wrong.
如何修改或扩展此隐藏语句，使其仅隐藏与 [ _]alpha[ _] 匹配的关键字?换句话说，我想要以下转换:
How can I modify or expand this conceal statement so that it only conceals keywords that match [ _]alpha[ _]? In other words, I want the following conversions:
alpha_1 => α_1
alpha => α
alphabet => alphabet
注意:这类似于 这个问题，但是它似乎稍微复杂一些，因为我要匹配的组环境是空格和下划线.天真地定义如下语法区域会导致各种错误:
Note: This is similar to this question, however it seems like it's slightly more complicated since the group environment I want to match is spaces and underscores. Naively defining a syntax region like the following makes things all kinds of wrong:
syn region scalaGreekGroup start="[ _]" end="[ _]"
提前致谢！
推荐答案
修改模式以仅匹配由单词分隔的名称边界或下划线:
Modify the pattern to match only the names delimited by word boundaries or underscores:
:syntax match scalaNiceKeyword '\(_\|\<\)\zsalpha\ze\(\>\|_\)' conceal cchar=α
