balkon: Text layout engine built on top of HarfBuzz.

[ gpl, library, text ] [ Propose Tags ] [ Report a vulnerability ]

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.

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.

[back to package description]

Balkón

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.
