Spreadsheet Examples

nums

This rather simple spreadsheet is comprised entirely of ints.

1 2 3 4
10 20 30 40

grades

In this spreadsheet we can see that Joshua Bloch is rocking out the Java assignments in 425, Dan Grossman is allowing his subconscious disdain for Java to affect his ability with those assignments, and Shannon O'Ganns was failing poorly enough to seemingly resort to some sort of subversion of the grading process.

Name Java List SML Calendar SML Hearts SML Card Game Java HOF SML Binary Tree SML Pattern Matching
Max 100 104 100 104 100 100 105
Joshua Bloch 100 85 80 75 100 70 65
Harry Q. Bovik 80 81 82 83 84 85 86
Dan Grossman 75 104 100 104 80 100 105
Shannon O'Ganns 70 40 0 120 120 130 140

hockey

In this spreadsheet we have the three greatest hockey players of all time with some of their stats. Although not particularly interesting from a computer science perspective, it is remarkable that Wayne Gretzky has more assists than the year of his birth.

Name Uniform Number Birth Year Games Played Goals Assists
Bobby Orr 4 1948 657 270 645
Wayne Gretzky 99 1961 1487 894 1963
Mario Lemieux 66 1965 915 690 1033

Basis Library

Option

String

Int

List

Code To Implement

NOTE: For both CSV and Spreadsheet functions, you may assume that all rows will have the same number of columns.

Csv

read_csv

fun read_csv(csv:string) : string list list =
   raise NotYetImplemented

It is highly recommended that you use the String fields function. NOTE: fields is curried. You have been provided with an example usage of fields in string_fields_example.sml: 

fun is_separator(c : char) : bool =
        c = #"/"

val split_path = String.fields is_separator "git/425/sml/spreadsheet"

which when run will bind split_path to ["git","425","sml","spreadsheet"]

Spreadsheet

types

datatype cell

datatype cell = EMPTY | TEXT of string | INTEGER of int

type sheet

type sheet = cell list list

sheet creation and access functions

For clarity, we will provide what select functions evaluate to for this spreadsheet:
