# Help
|
||||
|
||||
## Running the tests
|
||||
|
||||
Each exercise contains a test file.
|
||||
Run the tests using the `bats` program.
|
||||
|
||||
```bash
|
||||
bats hello_world.bats
|
||||
```
|
||||
|
||||
`bats` will need to be installed.
|
||||
See the [Testing on the Bash track][tests] page for instructions to install `bats` for your system.
|
||||
|
||||
[tests]: https://exercism.org/docs/tracks/bash/tests
|
||||
|
||||
## Help for assert functions
|
||||
|
||||
The tests use functions from the [bats-assert][bats-assert] library.
|
||||
Help for the various `assert*` functions can be found there.
|
||||
|
||||
[bats-assert]: https://github.com/bats-core/bats-assert
|
||||
|
||||
## Skipped tests
|
||||
|
||||
Solving an exercise means making all its tests pass.
|
||||
By default, only one test (the first one) is executed when you run the tests.
|
||||
This is intentional, as it allows you to focus on just making that one test pass.
|
||||
Once it passes, you can enable the next test by commenting out or removing the next annotation:
|
||||
|
||||
```bash
|
||||
[[ $BATS_RUN_SKIPPED == true ]] || skip
|
||||
```
|
||||
|
||||
## Overriding skips
|
||||
|
||||
To run all tests, including the ones with `skip` annotations, you can run:
|
||||
|
||||
```bash
|
||||
BATS_RUN_SKIPPED=true bats exercise_name.bats
|
||||
```
|
||||
|
||||
It can be convenient to use a wrapper function to save on typing:
|
||||
|
||||
```bash
|
||||
bats() {
|
||||
BATS_RUN_SKIPPED=true command bats *.bats
|
||||
}
|
||||
```
|
||||
|
||||
Then run tests with just:
|
||||
|
||||
```bash
|
||||
bats
|
||||
```
|
||||
|
||||
## Submitting your solution
|
||||
|
||||
You can submit your solution using the `exercism submit darts.sh` command.
|
||||
This command will upload your solution to the Exercism website and print the solution page's URL.
|
||||
|
||||
It's possible to submit an incomplete solution which allows you to:
|
||||
|
||||
- See how others have completed the exercise
|
||||
- Request help from a mentor
|
||||
|
||||
## Need to get help?
|
||||
|
||||
If you'd like help solving the exercise, check the following pages:
|
||||
|
||||
- The [Bash track's documentation](https://exercism.org/docs/tracks/bash)
|
||||
- [Exercism's programming category on the forum](https://forum.exercism.org/c/programming/5)
|
||||
- The [Frequently Asked Questions](https://exercism.org/docs/using/faqs)
|
||||
|
||||
Should those resources not suffice, you could submit your (incomplete) solution to request mentoring.
|
||||
|
||||
Check your code for syntax errors: paste your code into
|
||||
[https://shellcheck.net](https://shellcheck.net) (or [install it](https://github.com/koalaman/shellcheck#user-content-installing) on your machine).
|
||||
|
||||
Stack Overflow will be your first stop for bash questions.
|
||||
|
||||
* start with the [`bash` tag](https://stackoverflow.com/questions/tagged/bash) to search for your specific question: it's probably already been asked
|
||||
* under the bash tag on Stackoverflow, the [Learn more...](https://stackoverflow.com/tags/bash/info) link has _tons_ of good information.
|
||||
* the "Books and Resources" section is particularly useful.
|
||||
* the [`bash` tag](https://unix.stackexchange.com/questions/tagged/bash) on Unix & Linux is also active
|
||||
|
||||
## External utilities
|
||||
|
||||
`bash` is a language to write "scripts" -- programs that can call
|
||||
external tools, such as
|
||||
[`sed`](https://www.gnu.org/software/sed/),
|
||||
[`awk`](https://www.gnu.org/software/gawk/),
|
||||
[`date`](https://www.gnu.org/software/coreutils/manual/html_node/date-invocation.html)
|
||||
and even programs written in other programming languages,
|
||||
like [`Python`](https://www.python.org/).
|
||||
This track does not restrict the usage of these utilities, and as long
|
||||
as your solution is portable between systems and does not require
|
||||
installation of third party applications, feel free to use them to solve
|
||||
the exercise.
|
||||
|
||||
For an extra challenge, if you would like to have a better understanding of
|
||||
the language, try to re-implement the solution in pure bash, without using
|
||||
any external tools. There are some types of problems that bash cannot solve,
|
||||
such as floating point arithmetic and manipulating dates: for those, you
|
||||
must call out to an external tool.

# Darts
|
||||
|
||||
Welcome to Darts on Exercism's Bash Track.
|
||||
If you need help running the tests or submitting your code, check out `HELP.md`.
|
||||
|
||||
## Instructions
|
||||
|
||||
Write a function that returns the earned points in a single toss of a Darts game.
|
||||
|
||||
[Darts][darts] is a game where players throw darts at a [target][darts-target].
|
||||
|
||||
In our particular instance of the game, the target rewards 4 different amounts of points, depending on where the dart lands:
|
||||
|
||||
- If the dart lands outside the target, player earns no points (0 points).
|
||||
- If the dart lands in the outer circle of the target, player earns 1 point.
|
||||
- If the dart lands in the middle circle of the target, player earns 5 points.
|
||||
- If the dart lands in the inner circle of the target, player earns 10 points.
|
||||
|
||||
The outer circle has a radius of 10 units (this is equivalent to the total radius for the entire target), the middle circle a radius of 5 units, and the inner circle a radius of 1.
|
||||
Of course, they are all centered at the same point — that is, the circles are [concentric][] defined by the coordinates (0, 0).
|
||||
|
||||
Write a function that given a point in the target (defined by its [Cartesian coordinates][cartesian-coordinates] `x` and `y`, where `x` and `y` are [real][real-numbers]), returns the correct amount earned by a dart landing at that point.

|
||||
|
||||
## Floating Point Arithmetic
|
||||
|
||||
This particular exercise, since it deals with floating point arithmetic, is
|
||||
natural to rely on external tools (see below). As an extra challenging
|
||||
challenge, find a way to implement this with plain bash.
