Line Breaks

You work at a news agency. All of the writers write in plain text, and they all have "soft wraps" turned on in their editors, so all of the their lines are really, really long.

You need to take these text files, and break the lines up such that no line is longer than a certain number of characters (80, by default). You must not break up any words.

Examples

Let's say you have the following text, and you need to have a max line length of 20:

Jean shorts you probably haven't heard of them farm-to-table.

Another line.

The result would be:

Jean shorts you
probably haven't
heard of them
farm-to-table.

Another line

Lines should not have trailing spaces.

Extra

• Be able to handle empty lines in the input. For example, with a line length of 20 characters, using the input of:

Jean shorts you probably haven't heard of them farm-to-table.

Another line.

would result in:

Jean shorts you
probably haven't
heard of them
farm-to-table.

Another line

• Go through each file in the data directory and create new file where the text breaks at 80 characters. Add these new files to an output directory, and give them the same names as the original files.

Setup

• Fork
• Clone
• Turn on TravisCI for the fork by visiting https://travis-ci.org/profile/, clicking the "Sync now" button and scrolling down to find the repository to build.
• Create a new branch for your work using git checkout -b v1
• Implement specs and code
• Push using git push -u origin v1

Further Practice

This warmup can be completed multiple times to increase your comfort level with the material. To work on this from scratch, you can:

1. Add an upstream remote that points to the original repo git remote add upstream [email protected]:gSchool/line-breaks.git
2. Fetch the latest from the upstream remote using git fetch upstream
3. Create a new branch from the master branch of the upstream remote git checkout -b v2 upstream/master
4. Implement specs and code
5. Push using git push -u origin v2

Each time you do the exercise, create a new branch. For example the 3rd time you do the exercise the branch name will be v3 instead of v2.
