# Poetry

The poetry plugin provides the poetry directive, used to render poetry (or songs).

## Why?

### Typography

In regular text, there are two different meaning of a new line: a break between two paragraphs, and the line wrap.

When rendering poetry, we need a third one: the carriage return between two verse lines. This one should be different from the line wrap carriage return, otherwise one will not be able to tell apart these two: is a word displayed at the begenning of its line a new verse line, or the previous verse line, continuing on a new line because it is too long?

Generally, wrapped text is indented, whereas verse lines are not.

### Markdown

One could use carriage return (two white spaces at the end of a line) between verse lines, and paragraph break between stanzas, but:

- adding white spaces at the end of lines is painful;
- there is no easy way to render chorus (in a different way from verses).

## Usage

The directive takes only one argument `content`, containing the poetry to render. Carriage returns are respected.

Chorus are lines with `>` as a starting character.

Lines starting with `)` are consored/outdated/crossed out verses.

View example

    [[!poetry  content="""
    This is a verse
    Made of several lines

    > And here is the chorus
    > La la la!
    > A beautiful chorus

    Another verse
    A bit longer
    Than the previous one

    ) This one is deleted
    ) Because I did not like it

## CSS

This plugin is useless without some corresponding CSS. An example is given below.

CSS

    .poetry {
      padding-left: 1em;
      border-left: 0.1em solid lightgray;
      border-radius: 0.5em;
    }

    .poetry .stanza {
      padding-left: 1em;
    }

    .poetry .paren {
      font-style: italic;
      font-size: smaller;
      text-decoration: line-through;
    }

    .poetry .paren:hover {
      text-decoration: initial;
    }

    .poetry .chorus {
      margin-left: 0.1em;
      padding-left: 2em;
      border-left: 0.3em solid slategray;
    }

    .poetry .line {
      display: block;
      text-indent: -1em;
    }

## Example

This plugin is used to render songs on this choir's website.
