| + | ===== Purpose ===== | ||
| + | The purpose of this homework is to get you familiarized with the following concepts: | ||
| + | - basic TypeScript development | ||
| + | - use of data structures in TypeScript | ||
| + | - use of command line parameters | ||
| + | - reading data from files | ||
| + | - basic string splitting and processing | ||
| + | |||
| ===== What do you have to do ===== | ===== What do you have to do ===== | ||
| - | The purpose of the homework is to write an interpreter for the //Robot// language. The language is used to move a robot on a flat plane. The robot can go forward, backwards, turn or jump. | + | The purpose of the homework is to write an interpreter for the //Design// language. The language is used to draw geometric figures and and points. |
| + | |||
| + | Write an interpreter that receives a file with statements as parameter and writes a [[https://developer.mozilla.org/fr/docs/Web/SVG/Tutoriel|SVG]] file. If there was an error, it will output ERROR LINE followed by the line number: and the error text. | ||
| - | Write an interpreter that receives a file with commands as parameter and writes to the screen the position and rotation of the robot after each command. | + | The program receives two parameters: |
| + | * the file with statements | ||
| + | * the svg output file | ||
| - | * If the command was successful, it will output OK x, y, r (exactly like this) | + | A usage example: |
| - | * If there was an error, it will output ERROR LINE followed by the line number: and the error text. | + | |
| <code bash> | <code bash> | ||
| - | node main.js robot_commands.s | + | node main.js design.dsn canvas.svg |
| </code> | </code> | ||
| - | This will run the //robot_commands.s// file and write to the screen the position and rotation of the robot after every command or an error for the lines that have errors. | + | This will run the //design.dsn// file and write the drawing into the canvas.svg file. |

| - | ===== Robot Language ===== | ||
| - | === Robot Position === | + | ===== Design Language ===== |
| - | The robot has a position and a rotation. The position is expressed by a (x, y) pair expressed as integer numbers. The rotation of the robot is expressed in degrees and varies between 0 and 360. | + | The language is actually moving a pen. The pen's initial position is 0, 0. When drawing, the pen will move to the new position. |
| - | The status of the robot is expressed as (x, y, r), meaning: | + | ==== Variables ==== |
| - | * x, y the position | + | |
| - | * r the rotation in degrees | + | |
| - | === Starting Point === | + | All statements accept as parameters numbers or variables. Variables have the following format: |
| - | The robot starts from (0, 0, 90) meaning the position (0, 0) and the rotation 90 degrees. | + | <code> |
| + | %variable | ||
| + | </code> | ||
| + | Before it can be used, a variable needs to be assigned a value (using the //set// statement). | ||
