%countlist: commas
|
| Code: |
#echo %COUNTLIST(test|test|test|testb|testb|test'b|test'b)
|
test=3|testb=2|test'b=2
| Code: |
| #echo %COUNTLIST(test|test|test|testb|testb|test,b|test,b) |
test=4|testb=2
%countlist seems to not like commas. I have tried to escape the comma, but it made no difference. Any suggestions?
EDIT: I see now, this is a known bug. |

The problem is not the commas; it is the lack of quotes.
#echo %COUNTLIST("test|test|test|testb|testb|test,b|test,b")
Also this would work.
$var="test|test|test|testb|testb|test,b|test,b"
#echo %COUNTLIST($var) |

It's actually not a bug at all. The comma is used to separate parameters in function calls. You were passing "test|test|test|testb|testb|test" as the first parameter, "b|test" as the second parameter, and "b" as the third parameter. The countlist function only checks the first parameter, and correctly reports that test appears 4 times, and testb appears twice. This is expected behavior. Vijilante's correction is not a workaround to a bug, that's just the correct way to express a literal string. zScript does try to be forgiving whenever possible, but using quotes is the proper syntax, and will ensure that you get no unexpected results in edge cases such as this.

I am sorry, but, when using quotes or no quotes, a single parameter or multiple parameters the result is the same.
Any other ideas?
By the way, the documentation does not describe multiple parameters. Yes, I now understand how that works. Thank you!!! |
