10.1.3 Example: Creating a level 4 bullet item rule

In this example, we want to have a rule for level 4 bullets. The closest predefined rule is L3BulletItem, which we find in the lists.wml file. The definition of the L3BulletItem rule is:

# L3BulletItem specifies level 3 bulleted list item.
PARAGRAPH "L3BulletItem" TYPE List
{
  LEVEL 3
  KIND Bullet
  ACTIONS
  {
    write(*,listitem(paragraph(text())));
  }
}

We copy the L3BulletItem rule and edit the copy. We change the name to L4BulletItem, edit the comment, and simply change the level from 3 to 4. The definition of the L4BulletItem rule is:

# L4BulletItem specifies level 4 bulleted list item.
PARAGRAPH "L4BulletItem" TYPE List
{
  LEVEL 4
  KIND Bullet
  ACTIONS
  {
    write(*,listitem(paragraph(text())));
  }
}
