[ncl-talk] Possible bug or improvement for the function "str_index_of_substr"

[Yuqiang Zhang]

Hi Dear NCL developers,

I was using the "str_index_of_substr" to find the sub array recently, and
found some interesting thing about it.

For example,

a = "ABABA"
substr = "ABA"

i1 = str_index_of_substr(a, substr, 0)
print(i1)

The output is 0, which is "*ABA*BA" only, but actually I kind hope it could
find both "*ABA*BA" and "AB*ABA*". Any way to bypass that?

Thanks!
Regards,
Yuqiang
