Sort list - get indexes

[Emmanuel Delay]

I want to sort a list.  I'm not interested in getting back a list of the sorted values, I want a list of the indexes.

 

For example:

(getSortedIndexes (list "b" "a" "e" "f" "c") ) should return (list 1 0 4 2 3)

 

I feel like I asked this question before, but I can't find it

[Grrr]

Hi, look into the vl-sort-i function.

Oh yes, thanks.

 

(vl-sort-i (list  "b" "a" "e" "f" "c") '<) returns (list 1 0 4 2 3) .
