# Bob
|
|
|
|
Bob is a lackadaisical teenager. In conversation, his responses are very limited.
|
|
|
|
Bob answers 'Sure.' if you ask him a question, such as "How are you?".
|
|
|
|
He answers 'Whoa, chill out!' if you YELL AT HIM (in all capitals).
|
|
|
|
He answers 'Calm down, I know what I'm doing!' if you yell a question at him.
|
|
|
|
He says 'Fine. Be that way!' if you address him without actually saying
|
|
anything.
|
|
|
|
He answers 'Whatever.' to anything else.
|
|
|
|
Bob's conversational partner is a purist when it comes to written communication and always follows normal rules regarding sentence punctuation in English.
|
|
|
|
|
|
Run the tests with:
|
|
|
|
```bash
|
|
bats bob_test.sh
|
|
```
|
|
|
|
After the first test(s) pass, continue by commenting out or removing the
|
|
`[[ $BATS_RUN_SKIPPED == true ]] || skip`
|
|
annotations prepending other tests.
|
|
|
|
To run all tests, including the ones with `skip` annotations, run:
|
|
|
|
```bash
|
|
BATS_RUN_SKIPPED=true bats bob_test.sh
|
|
```

Inspired by the 'Deaf Grandma' exercise in Chris Pine's Learn to Program tutorial. [http://pine.fm/LearnToProgram/?Chapter=06](http://pine.fm/LearnToProgram/?Chapter=06)

## 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. Note that there are some types of
|
|
problems that bash cannot solve, such as performing floating point
|
|
arithmetic and manipulating dates: for those, you must call out to an
|
|
external tool.
|

## Submitting Incomplete Solutions
|
|
It's possible to submit an incomplete solution so you can see how others
|
|
have completed the exercise.
