Contour Interpreter
===================

[](#contour-interpreter)

Introduction
------------

[](#introduction)

This is a interpreter for the Contour project. It parses a basic function syntax for spreadsheets so that operations on tags can be performed.

Language Examples
-----------------

[](#language-examples)

### Variable Declarations & Assignments

[](#variable-declarations--assignments)

- Variables can be assigned with arithmetical/boolean operators and expressions and also tag expressions to link to other cells on other sheets.
- For an integer "num" with value 7:

```
  let num = 7

```

- For a string "name" with value "Alice":

```
 let name = "alice"

```

- For a variable "cellVal" that links to the spreadsheet cell referenced as #(row, col) + 7

```
let cellVal = #(row, col) + 7

```

### Conditional Statements :

[](#conditional-statements-)

- Multiline for clear understanding
- Can use boolean operators to link statements.
- If statements can nest
- For an if statement to see if the a string variable "name" is equal to "alice" and if so then set variable "correctName" to true and if not then set name to the value of cell (2, name) :

    ```
     if (name = "alice")
     then let correctName = true
     else then let name = #(2, name)

    ```
- Another example if statement. Notice how & and 'and' can be used in the exact same way and will produce the same result. The return keyword returns the result of the function :

    ```
      if (name = "alice" & age = 22)
     then return 1
     else if (name = "bob" and age = 23)
     then return 2
     else then return 0

    ```

If there are any errors in the function code then it is output to the user, giving the type of error and the location of it also.
