ruby ./app.rb data.txt

Notes

app.rb gets its data set from data.txt. Here is a sample data set.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Maecenas consectetur malesuada velit, sit amet porta magna maximus nec. Aliquam aliquet tincidunt enim vel rutrum. Ut augue lorem, rutrum et turpis in, molestie mollis nisi.

Ut dapibus erat eget felis pulvinar, ac vestibulum augue bibendum. Quisque sagittis magna nisi. Sed aliquam porttitor fermentum. Nulla consequat justo eu nulla sollicitudin auctor. Sed porta enim non diam mollis, a ullamcorper dolor

molestie. Nam eu ex non nisl viverra hendrerit. Donec ante augue, eleifend vel eleifend quis, laoreet volutpat ipsum. Integer viverra aliquam nulla, ac rutrum dui sodales nec.

Sed turpis enim, porttitor nec maximus sed, luctus pretium elit. Sed sodales imperdiet velit, vitae viverra erat commodo non. Nunc porttitor risus sit amet quam faucibus, et luctus ex fringilla. Mauris quis urna non lacus

tempor iaculis vitae quis dolor. Nam vitae pulvinar lacus, quis varius erat. Etiam lobortis orci vitae elementum tempor. Praesent convallis euismod enim vel vestibulum. Proin vitae eros vitae nisi cursus dapibus vitae

at ipsum. Phasellus sed tempor eros, non scelerisque nunc. Nullam condimentum ex ultrices, ultrices ante sit amet, rhoncus nibh. Aliquam fermentum vulputate fringilla. Ut risus orci, pharetra eu tellus vel, fringilla feugiat dolor.

Nunc quis elit quam. Sed aliquet, nibh ut sagittis egestas, lorem tortor laoreet diam, non maximus lectus dolor dignissim eros. Sed vehicula mi id aliquet aliquam. Vestibulum sed lacus et

neque dictum convallis in vitae mauris. Etiam varius augue vel mattis tempor. Curabitur mattis facilisis metus, tempus consectetur quam aliquam sed. Mauris velit orci, efficitur sit amet nisl in

With the following highlights as input:

highlights = [{
  start: 20,
  end: 35,
  comment: 'Foo'
}, {
  start: 73,
  end: 92,
  comment: 'Bar'
}, {
  start: 50,
  end: 98,
  comment: 'Baz'
}]

HTML output is saved in output.html that generates highlighted paragraphs with unique random colors.

HtmlMarker.new(data, highlights).to_html_doc produces the following html page.

Possible Improvements

• Scale solution to cater for more than just <p> tags
• Allow proper overlapping of highlights and color them uniquely
• Find a better solution than hard coding indices when inserting highlighting marks
• Code could benefit from automated tests
  • random_color almost splipped through without registering the already used color
