The Note that here
\br
macro inserts a visible newline between two lines without creating a paragraph, for example:ab\br[]cd
which renders as:
ab
cd
[]
is an empty
macro argument used for convenience to separate the \br
from the cd
text that immediately follows.The recommended syntax is the insane version which simply uses a newline as in:Note that the newline only works as a line break if surrounded by two inline macros as mentioned at newline removal.
ab
cd
which renders as:
ab
cd
If for some reason you want to have an actual literal newline in your output outside of literal arguments, just escape the newline with a backslash as for escaping anything else.
There is basically just one application for line breaks: poetry, which would be too ugly with code blocks due to fixed width font:
Even as the sun with purple-coloured face
Had taken his last leave of the weeping morn,
Rose-cheeked Adonis tried him to the chase;
Hunting he loved, but love he laughed to scorn;
Sick-thoughted Venus makes amain unto him,
And like a bold-faced suitor begins to woo him.
"Thrice fairer than myself," thus she began,
The field's chief flower, sweet above compare,
Stain to all nymphs, more lovely than a man,
More white and red than doves or roses are;
Nature that made thee, with herself at strife,
Saith that the world hath ending with thy life.
