Summary description: Bold latin and greek characters through simple prefix characters
Announcement text:
Description The boldtensors package provides a highly efficient shorthand for typesetting Latin and Greek characters in bold and blackboard-bold layouts. It is specifically designed for the requirements of Theoretical Physics and General Relativity, where a clear visual distinction between geometric tensor objects and their components or scalars is essential. The package uses active characters (~ and ") to keep the source code clean and readable: - `$~T$` produces a bold tensor T. - `$"R$` produces a blackboard-bold symbol ℝ. Key Features: • Engine Independent: Fully compatible with both classical pdfLaTeX (using NFSS) and modern LuaLaTeX (using unicode-math and OpenType fonts). • ISO Compliance: Includes the bt-isodiff sub-package for upright differential operators according to ISO 80000-2. • Accurate Metrics: Correct placement of subscripts, superscripts, and accents (like \hat{~T}) by using native math characters instead of boxes. • Micro-Typography: Preserves perfect kerning and font-specific metrics.
The package’s Catalogue entry can be viewed at https://ctan.org/pkg/boldtensors The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/boldtensors/
