In textshaping: Bindings to the 'HarfBuzz' and 'Fribidi' Libraries for Text Shaping

textshaping 1.0.3

• Fixed a signed integer overflow in the the fix for ragg#193

textshaping 1.0.2

• Fixed a bug in bidi embedding arrangement when shaping a single line (ggplot2#6497)
• Fixed a bug in shape caching due to a weak vector hash implementation (ragg#193)
• Fixed a bug in line positioning when line containes mix of different sizes

textshaping 1.0.1

• Fixed a bug where hard line breaks where ignored if the line consisted of multiple embeddings (marquee#58)
• Fixed a bug where newline characters would increase the width of a line and lead to an empty line getting inserted in some situations (marquee#55)

textshaping 1.0.0

• Added lorem_text() and lorem_bidi() for generating nonsense text in various scripts
• Added plot_shape() to plot the result of a shaping along with the metrics
• Rewrite of the shaping engine to honor global direction of text. It introduces a direction argument to shape_text() that defaults to auto, meaning that it is deduced from the content of the shaped text. align gets two new settings that responds to the global direction of the text. "auto" will chose between "left" and "right" and "justified" will choose between "justified-left" and "justified-right" depending of the global direction is ltr or rtl. Lastly the soft break locations are now based on ICU and thus better support ideographic scripts such as Han/Kanji/Hangul.
• Textshaping now properly supports soft hyphens in that a hyphen is rendered if a soft-wrap happens at a soft hyphen (#52)

textshaping 0.4.1

• Make compiled code somewhat less assumptive about the correctness of the input
• Fix a bug from too aggressive early exiting shaping of strings with no max width (#45)
• Fixed a mismatch between the default values of the width argument in shape_text() and systemfonts::match_fonts() (#44)
• Updated text_width() to take the same inputs as shape_text()

textshaping 0.4.0

• Full rewrite of shape_text() to allow proper font-fallback, bidi text support, support for font-features, spacers, new align settings, etc.

textshaping 0.3.7

• Prepare for Arm Windows

textshaping 0.3.6

• Fix a bug in fallback font loading which would crash the process if the font failed to load (#23)
• Fixed bug that would reset fallback to the original font for short strings (#25)

textshaping 0.3.5

• Address an UBCSAN issue in packages linking to textshaping
• Remove a few compiler warnings

textshaping 0.3.4

• Prepare textshaping for UCRT support
• Address upstream changes in cpp11

textshaping 0.3.3

• Support static linking on macOS (#17, @jeroen)

textshaping 0.3.2

• Avoid overindexing fallbacks when no fallback is found

textshaping 0.3.1

• Try to avoid ASAN issue reported by CRAN

textshaping 0.3.0

• Add support for performing font fallback as part of the single-line shaping
• Provide support for non-scalable fonts

textshaping 0.2.1

• Fix issues with the Solaris mock solution

textshaping 0.2.0

• Update C API to prepare for font fallback
• Make sure it compiles on Solaris without system dependencies

textshaping 0.1.2

• Fix a bug in the interaction with the systemfonts font cache that could cause random crashes on some mac installations.

textshaping 0.1.1

• Small changes to comply with next cpp11 version

textshaping 0.1.0

• First release. Provide access to HarfBuzz shaping and FriBidi bidirectional script support.
