When we define just 2 forms in pattern, it means that first form is for num = 1 and second form for anything else. So, this pattern will have the same output as in example above:

pattern = "I have sold <<1>> <<1[item/items]>>."

We can modify pattern even further using the $d variable:

pattern = "I have sold <<1[$d item/$d items]>>"

$d will get replaced with actual value of argument, so output will be the same as in both examples above.


Also we can leave empty any of the forms, so there will be no return value. Good example is time format:

pattern = "Remaining time: 1[/1 minute and /$d minutes and ]>><<2[1 second/$d seconds]>>"
 
msg = zo_strformat(pattern, min, sec)

As we do not have defined form for zero value for minutes, output will be:
if min = 0, sec = 1
msg = "Remaining time: 1 second"

if min = 0, sec = 5
msg = "Remaining time: 5 seconds"

if min = 5, sec = 0
msg = "Remaining time: 5 minutes and 0 seconds"
