Sublime Text 中 >= 和 <= 运算符的语法高亮 [英] Syntax highlighting for >= and <= operators in Sublime Text

问题描述

我正在尝试为 Matlab 运算符 >= 和 <= 获得正确的语法突出显示.目前，只有 < 和 > 被高亮显示——而不是 =.但是例如== 突出显示.

I am trying to get proper syntax highlighting for the Matlab operators >= and <=. Currently, only < and > are highlighted -- not the =. But e.g. == is highlighted.

我查看了 Matlab.tmLanguage 文件，其中包括 >= 和 <=在运算符正则表达式中.

I've looked in the Matlab.tmLanguage file, and both >=and <= are included in the operator regex.

这里有什么问题?

推荐答案

问题在于完整的正则表达式，可在以下位置找到:

The issue is with the complete regex, which is found under:

</dict>
<key>operators</key>
<dict>
    <key>comment</key>
    <string>Operator symbols</string>
    <key>match</key>
    <string>\s*(==|~=|&gt;|&gt;=|&lt;|&lt;=|&amp;|&amp;&amp;|:|\||\|\||\+|-|\*|\.\*|/|\./|\\|\.\\|\^|\.\^)\s*</string>
    <key>name</key>
    <string>keyword.operator.symbols.matlab</string>
</dict>

问题在于 或 的子表达式的顺序(|>|>=|<|<=).例如.> 在 >= 之前匹配，然后根本不匹配.所以解决方案是改变子表达式的顺序，先匹配较长的.IE.将 match 字符串更改为:

The issue is the order of the or'ed sub-expressions (|>|>=|<|<=). E.g. > is matched before >=, which then isn't matched at all. So the solution is to change the order of the subexpressions, matching the longer first. I.e. change the match string to:

 \s*(==|~=|>=|>|<=|<|&|&&|:|\||\|\||\+|-|\*|\.\*|/|\./|\\|\.\\|\^|\.\^)\s*
