Rebol Programming/Language Features/Parse/Simple splitting

String parsing involves simple splitting: parse "this is a string" none ; == ["this" "is" "a" "string"] By providing NONE as the PARSE rule, we are asking PARSE to break a string into a block of string(s) based on whitespace: whitespace: charset [#"^A" - #" " "^(7F)^(A0)"] and common delimiters: common-delimiter: charset ",;" To facilitate CSV splitting, quotation marks are handled specially (see the CSV example). Examples Empty string parse "" none ; == [] No delimiters in the input string parse "redbluegreen" none ; == ["redbluegreen"] Space parse "red blue green" none ; == ["red" "blue" "green"] Comma parse "red,blue,green" none ; == ["red" "blue" "green"] Tab parse "red^-blue^-green" none ; == ["red" "blue" "green"] Semicolon parse "red;blue;green" none ; == ["red" "blue" "green"] Newline string: { red blue green } parse string none ; == ["red" "blue" "green"] Leading and trailing whitespaces are ignored parse " 1 " none ; == ["1"] A sequence of whitespaces is equivalent to one whitespace parse "1 2" none ; == ["1" "2"] Leading common delimiter delimits an empty substring parse ",1" none ; == ["" "1"] One trailing common delimiter is ignored parse "1," none ; == ["1"] A sequence of common delimiters delimits empty substrings between them parse "1,,2" none ; == ["1" "" "2"] CSV parse {"red","blue","green"} none ; == ["red" "blue" "green"]
