Need a better example to show defining functions with format strings

Open haoysRPI opened this issue 4 years ago • 1 comments

Please complete the information below:

Where is the problem?

Section "Functions: Format Strings"

What is the problem?

We provide an example to show defining functions with format string. But in the function takes_format_string, there is no function body tells us how to handle $format and $args, it would be much better to provide an example in the function.

Please don't change anything below this point.
