balkon: Text layout engine built on top of HarfBuzz.

[ gpl, library, text ] [ Propose Tags ]

Given an input text and formatting options, Balkón produces an inline layout with defined glyph positions and box coordinates, all within a containing unit called a paragraph. See Data.Text.ParagraphLayout.Rich.

Internally, HarfBuzz is used to shape individual runs of text, each of which fits within one line and has a constant script, direction, language, and formatting. Balkón abstracts this so that you can provide text with any mix of these attributes and a desired line width for line breaking.

Additionally, Balkón can be used for breaking an inline layout into pages. See Data.Text.ParagraphLayout.

Repository | Issue tracker

Haskell library built on top of HarfBuzz to lay out text within a paragraph.

Just like flowers on a balcony, text must be arranged carefully within a limited space and put into neat little boxes.

Intended to be the inline layout engine for The Argonaut Stack.
