Block Folding

In the folded block style, folding does not apply to line breaks or empty lines that preced or follow a

text line containing leading white space. Note that such a line may consist of only such leading white

space; an empty block line is confined to (optional) indentation spaces only. Further, the final line

break and empty lines are subject to chomping, and are never folded. The combined effect of these

rules is that each “paragraph” is interpreted as a line, empty lines are used to present a line feed, the

formatting of “more indented” lines is preserved, and final line breaks may be included or excluded

from the node's content information as appropriate.

Flow Folding

Folding in flow styles provides more relaxed, less powerful semantics. Flow styles typically depend

on explicit indicators to convey structure, rather than indentation. Hence, in flow styles, spaces preceding

or following the text in a line are a presentation detail and must not be considered a part of the node's

content information. Once all such spaces have been discarded, folding proceeds as described above.

In contrast with the block folded style, all line breaks are folded, without exception, and a line consisting

only of spaces is considered to be an empty line, regardless of the number of spaces. The combined

effect of these processing rules is that each “paragraph” is interpreted as a line, empty lines are used

to present a line feed, and text can be freely “more indented” without affecting the node's content in-

formation.
