Reflow and text layout

Text flows around canvases#

When a canvas sits on top of a Rich Text canvas, the text flows around it rather than disappearing underneath. Move the canvas and the text reflows.

For a picture, you choose the behaviour in the toolbar: Wrap flows the text around the picture, and Leave blank leaves the space empty.

Each notebook also has a Page layout setting, Reflow or Fixed-width, in the This notebook section of Settings ▸ Appearance.

Where lines break#

DunneNote chooses line breaks so the meaning survives the break.

Numbers never split. A number is kept whole, with its currency sign, sign, thousands separators, decimal point and percent sign. $12.50, -3.14159, 1,250,000 and 45% never break across two lines.

Other break points are ranked. Where a long run has no space, DunneNote prefers to break, in order:

1. at a space,
2. at a path separator (/ or \),
3. at punctuation common in code and addresses (_ - : . ? & # =),
4. at a change from lower to upper case in camelCase words.

A run with more than one decimal point, such as the version number 1.2.3, is not treated as a number and can break at its dots.

If nothing fits, it overflows. A unit that is too wide and has no acceptable break point, such as a long hash, is kept intact and allowed to run past the edge. It is never broken or hyphenated in a place that would change how it reads. An overflow is obvious, whereas a silently broken number is not.

Limits#

• The rules assume . is the decimal point and , groups thousands. Numbers written the other way round, as in much of Europe, may break differently.
• Text flows around a canvas's rectangle, not around the shape of what's in it.
