# Advent of Code 2021
Using the [Advent of Code 2021](https://adventofcode.com/2021/) puzzles to become more proficient in [Go](https://golang.org/).
## Environment Variables
### AOC_SESSION_TOKEN
Required for this application to automatically download your user-specific input files for each puzzle. You can find your session token in adventofcode.com's session cookie in your browser.
If not set, the application will not be able to automatically download puzzle inputs. You will have to download each manually and save it to the correct location, e.g. `./day01/input.txt`.
### AOC_LOG_LEVEL
Sets the [logrus](https://github.com/Sirupsen/logrus) log level. Valid values are `panic`, `fatal`, `error`, `warn`, `info`, `debug`, and `trace`. Defaults to `warn` if not set.
## Makefile
This repo's [`Makefile`](./Makefile) automates many useful operations.
### make setup
Downloads and installs [Go 1.17.3](https://go.dev/dl/) and downloads all of this application's package dependencies.
### make test
Runs all unit tests.
### make build
Builds the `advent-of-code-2021` executable in the current directory.
### make clean
Deletes all build artifacts from the current directory, i.e. the `advent-of-code-2021` executable.
### make run
Builds the `advent-of-code-2021` executable and runs a single day's solution. Specify the day by setting the `DAY` parameter in the command line. Optionally, you can also set the `LOG_LEVEL` variable, otherwise it will default to `warn`.
```
make run DAY=1 [LOG_LEVEL=trace]
```
### make run-all
Builds the `advent-of-code-2021` executable and runs all solutions for all days. Optionally, you can also set the `LOG_LEVEL` variable, otherwise it will default to `warn`.
```
make run-all [LOG_LEVEL=trace]
```
### make install
Builds the `advent-of-code-2021` executable and installs it in the `$GOPATH/bin` directory.
### make uninstall
Deletes the `advent-of-code-2021` executable from the `$GOPATH/bin` directory.
## Day 0 Mock Puzzle
This repo also contains a day 0 mock puzzle to do some integration testing of all things int he common package prior to the day 1 puzzle unlocking. It reads in a list of users from the input file and calculates their ages from their birthdays. Part 1's answer is the name of the oldest user and part 2's answer is that person's current age.
```
$ make run DAY=0
go build
AOC_LOG_LEVEL=warn ./advent-of-code-2021 0
Part 1 Answer: Joe Schmoe
Part 2 Answer: 38
