Using regex match string that start with dot excluding doubles

Question

I'm looking for a regex to split following string:

.name "Collector Show Stress" .target "target" .curio_result_type "negative" .chance 80% .stress 10.0 .on_hit true .on_miss false.queue true

into: .name "Collector Show Stress" .target "target" .curio_result_type "negative" .chance 80% .stress 10.0 .on_hit true .on_miss false .queue true

I've used following regex to match but it also splits the double: \\.[^.]+

The result I get is: .name "Collector Show Stress" .target "target" .curio_result_type "negative" .chance 80% .stress 10 .0 .on_hit true .on_miss false .queue true

I'm basically a newbie when it comes to regex so any help is appreciated.

I'm using the regex in a C# console app.

Thanks in advance!

To match your example data, you could match the available options for the second part:

\.[^.\s]+ (?:"[^"]+"|true|false|[0-9]+(?:\.[0-9]+)?%?)

Explanation

• .[^.\\s]+ Match . and 1+ occurrences of any char except a dot or whitespace char
• (?: Non capture group
  • "[^"]+" Match from the opening till the closing double quote "..."
  • | Or
  • true Match literally
  • | Or
  • false Match literally
  • | Or
  • [0-9]+(?:\\.[0-9]+)? Match 1+ digits with an optional decimal part
  • %? Match an optional percentage sign
• ) Close group

A less stricter pattern might be to match not a dot, or match a dot when followed by a digit

\.[^.]+ (?:[^.\s]|\.(?=[0-9]))+

Explanation

• .[^.]+ Match a dot followed by 1+ times any char except a dot
• (?: Non capture group
  • [^.\\s] Match any char except a dot or whitespace char
  • | Or
  • \\.(?=[0-9]) Match a dot asserting a digit directly to the right
• )+ Close group and repeat 1+ times
