Hi all, I want to sort a file by line alphabetic order. It appears it works at once as I write an idea ! Rebol is great ! str: copy [] foreach l (sort read/lines %my-file) [append str join l "^/"]
But I haven't thought of blank line which are empty string in the sort read/lines resulting block. I try using the string length. But I don't understand the following evaluations : >> t: ["" "" "one" "two"] >> foreach i t [print length? i] 0 0 3 3 >> foreach i t [if length? i [print i]] one two >> foreach i t [if length? i <> 0 [print i]] ** Script Error: length? expected series argument of type: series port tuple struct ** Near: if length? i <> 0 >> foreach i t [if (length? to-string i <> 0) [print i]] one two ---- What would be the best solution to get rid of the empty strings ? (or of any empty values of a block, be they string or of any type? Could you give me a pointer to the explanation of this in the official doc ?
