2016

2016

I use Typescript on ubuntu 16.04.

Usage

1. Install the depenencies with npm install.
2. Get the puzzle inputs from year 2016 of advent of code for the desired days as input.txt into the proper folders.
3. Run the code with the start script, to get the solution.

Scripts

Runnable scripts are defined in package.json.

Type	Run	Description
Start	npm start ${folderName}	runs the code with the data from input.txt in the selected folder.
Test	npm test ${folderName}	runs the code with test inputs specified in test.ts file.
Lint	npm run lint	Check the codestyle. It is run before each commit, to ensure consistent style.
Diff	npm run diff ${day}	Check the difference in my solution between the first and the second task code. Where day is the number of the day, padded to 2 characters.

Where ${folderName} is in the form of ${day}_${task}, where day is padded to 2 characters and task can be 1 or 2. (E.g.: 02_1).

Tips for incremental development

• You can copy the folders.
  • The input.txt usually does not change.
  • index.ts is independent of the folder, do not need modification.
  • If you copy the first task folder in VSCode the folder name will automatically increase.
    • E.g: 02_1 -> copy -> paste -> 02_2.
• solution.ts has to have a function solution(input: string[]): string function.

Debug

I debug my code with VSCode. I've added launch configs to achieve that easily and repeatable.

Debug with test data

1. Add a breakpoint to checkResult function in test.ts file in the actual ${day}_${task} folder.
2. Add the desired breakpoints.
3. Step into any file in that folder when you lauch: Run tests for current day.
4. Now you can check data in Debug menu and try out code in Debug console.

If you'd like to debug with custom data, feel free to add that data as the first test, into test.ts file into the testdata array (usually data) in the form of {input: string[], expected: string}.

Debug on actual input

1. Get the input.txt file for the selected folder, if you haven't yet done so.
2. Add a breakpoint to evaluateInput function in index.ts file in the actual ${day}_${task} folder.
3. Add the desired breakpoints.
4. Step into any file in that folder when you lauch: Debug on input.
5. Now you can check data in Debug menu and try out code in Debug console.

Debug on Windows

You need to reset the debug session after the first run to stop on breakpoints with VSCode.

Don't forget to add a breakpoint in test.ts/index.ts to make sure it stops there.

Solution: use "protocol": "inspector" on windows in launch config.
