YAML 中的字符串插值
问题描述：
在 Perl 中，我可以执行以下操作:
In Perl I can do something like the following:
my $home = "/home";
my $alice = "$home/alice";
我可以在 YAML 中执行以下操作吗:
Can I do something like the following in YAML:
Home: /home
Alice: $Home/alice
所以爱丽丝"到底是有效的/home/alice?
So "Alice" is effectively /home/alice in the end?
答
不幸的是，你运气不好.要执行您想要的操作，您需要从视图文件(或任何地方)传入 $home 并将其插入到您的 yaml 条目中，这可能类似于:
Unfortunately, you're out of luck. To do what you want you'd need to pass in $home from a view file (or wherever) and interpolate it in your yaml entry, which could possibly look something like:
Alice: ! '%{home}/Alice'
