英文:
s///r; breaks syntax highlighter in Sublime
问题
我有一个Perl脚本，我正在使用Sublime编辑器。
在下面这行代码之后，语法高亮器出现问题。
my $new = ($old =~ s/cat/dog/r);
这是因为/r。但为什么呢？
如何解决这个问题或有没有其他选择？
英文:
I have a Perl script and editor I'm using is Sublime.
After the below line of code, the syntax highlighter breaks.
<br>my $new = ($old =~ s/cat/dog/r);<br>
This is because of /r. But why?
How to tackle this problem or any alternatives?

这是您版本中存在的问题，即v3.1.1，也称为构建3176。
这个问题在v3.2，也称为构建3200中已经修复。
如果您拥有许可证，升级到最新的v3.x（v3.2.2）在您当前的许可证下是免费的。
然而，我强烈建议升级到最新版本的Sublime Text 4，它是Build 4143。我使用开发版本，稍微领先于公共版本，您的代码在那里也被正确地突出显示：
代码在Build 4143中看起来一样。
如果您是Sublime Text的持牌用户，您需要一张新的ST4许可证，但有如此多的新功能和改进，远远超过旧版本，支持开发人员绝对是值得的。
英文:
This is a problem that exists in your version, v3.1.1 aka build 3176.
This was fixed in v3.2 aka build 3200.
Upgrading to the latest v3.x (v3.2.2) is covered under your current license, if you have one.
However, I strongly recommend updating to the latest version of Sublime Text 4, which is Build 4143. I use the dev builds, which are slightly ahead of the public builds, and your code is highlighted correctly there as well:
The code looks the same in Build 4143.
If you're a licensed user of Sublime Text you'll need a new license for ST4, but there are so many new features and improvements over the old version that it's definitely worth it to support the developers.

r修饰符是在5.14版本中添加的。您的编辑器的高亮显示器显然不知道这个变化。
您可以改用以下方式：
my $new = $old;
$new =~ s/cat/dog/;
合并的写法：
( my $new = $old ) =~ s/cat/dog/;
英文:
The r modifier was added in 5.14. Your editor's highlighter apparently isn't aware of that change.
You could use the following instead:
my $new = $old;
$new =~ s/cat/dog/;
Combined:
( my $new = $old ) =~ s/cat/dog/;
