pikchr 1.1.1

CRAN release: 2026-06-14

Bug fixes

  • Fixed a memory leak in the C interface (pikchr_c): the SVG buffer returned by pikchr() was never freed, leaking on every diagram render.
  • Guarded the C interface against a possible NULL return from pikchr() that could crash the R session.
  • Fixed the height argument default in pikchr(), which never fell back to the SVG viewBox height and produced an empty height: CSS rule.
  • Aligned the documented argument defaults of pikchr() (width, height, fontSize, fontFamily, align) with the actual function defaults.

Other

  • Regenerated the package logo with a geometrically regular hexagon (the previous SVG was horizontally squished) and fixed an invalid <def> element (now <defs>) in the logo source.

pikchr 1.1.0

CRAN release: 2026-04-07

New features

  • Quarto and RMarkdown improvements: The knitr engine now supports fig.cap (figure captions with <figure>/<figcaption> in HTML), fig.alt (accessibility alt text via aria-label), and fig.align as standard knitr options.
  • Non-HTML output support: Automatic PNG conversion for all non-HTML formats including DOCX, EPUB, and Typst (previously only LaTeX/PDF was supported).
  • DPI-aware PNG conversion: The dpi chunk option (default 150) controls PNG resolution for non-HTML outputs.
  • Error detection: Pikchr compilation errors now produce informative warnings with the error message, instead of silently embedding invalid markup.
  • Quarto cross-referencing: Chunks with labels starting with fig- receive an HTML id attribute for Quarto cross-reference compatibility.

Improvements

  • Replaced message(), warning(), and stop() with cli::cli_inform(), cli::cli_warn(), and cli::cli_abort() for consistent and user-friendly messaging.
  • Removed dplyr, purrr, and rlang from Imports, replaced with base R operations for a lighter dependency footprint.
  • Replaced tidyverse in Suggests with specific packages (rmarkdown).
  • Updated authors list.
  • Removed compiled objects (.o, .so) from src/.
  • Cleaned up commented-out code and removed duplicate engine registration.

pikchr 1.0.3

CRAN release: 2025-09-19

Bug fix

  • Corrected automatic detection of LaTeX output: when knitting to PDF, the SVG diagram is now converted to a PNG image using the rsvg package, ensuring compatibility with LaTeX-based outputs.

pikchr 1.0.2

Bug fix

  • Adjusted SVG attribute handling to prevent false “NAs introduced by coercion” warnings caused by unexpected coercion of non-numeric attributes.

pikchr 1.0.1

CRAN release: 2025-03-31

  • updated pikchr source code to version 1.0

pikchr 1.0.0

  • Added a NEWS.md file to track changes to the package.
  • Embedded Google Fonts in SVG Files: Added functionality to embed Google Fonts directly into the generated SVG files, improving the portability and visual consistency of diagrams.
  • Improved Processing in RMarkdown: Enhanced integration with RMarkdown for smoother and more efficient rendering of diagrams within documents.
