rpic 0.11.3

Tracks the rpic engine from 0.6.2 to 0.11.3. The R functions and their arguments are unchanged; everything below is reached through the pic source.

  • New pic extensions, all opt-in: canvas (fixed page), per-string font attributes (bold, italic, mono, font, fontsize, big, small), rotated and aligned labels, colour literals rgb(r, g, b) and 0xRRGGBB, variables and expressions in colour position, thin, and link "<url>" for clickable objects in SVG output.
  • animate grew from three effects to a full set: move, highlight, slide, morph, type, scramble and wiggle, plus out, repeat, yoyo, ease, stagger, a partial draw from ... to ..., and draggable objects.
  • rpic_manifest() bundles gain an objects array (id, kind, bounding box and source position of every drawn object) and, when draggable is used, an interactions array.
  • Better compatibility with ‘dpic’: extension words such as after, repeat and previous no longer shadow identifiers, so sources that use them as variable or macro names compile.
  • Recursive macro expansion is no longer exponential in its depth.
  • Robustness: deeply nested input is rejected with a diagnostic instead of overflowing the stack, and invalid_color warnings carry a source position.
  • Rust 1.88 or later is now required to build from source (SystemRequirements).

rpic 0.6.2

CRAN release: 2026-07-15

  • Track rpic 0.6.2 (the 2026-07 audit series): always-valid SVG for negative dimensions, canvas bounds that contain arrowheads and math fragments, dpic-parity fixes for chop/continue/dead for bodies, and structured eval-phase diagnostics with include attribution.
  • Internal: the option builder is resilient to additive engine option fields.

rpic 0.6.1

  • Track rpic 0.6.1 (rpic-core/rpic-render from crates.io; previously 0.1.0).
  • New texlabels argument on rpic_svg(), rpic_png(), rpic_pdf() and rpic_manifest(), and as a knitr chunk option: fully $...$-delimited labels are typeset as TeX math, natively (the math renderer is now registered — it previously was not, so math labels fell back to literal text).
  • circuits = TRUE is now a compile option instead of prepending the library to the source: compile-error positions stay relative to your own input. The library can also be loaded in-source with copy "circuits".
  • Structured errors: compile failures are raised as a classed rpic_error condition; e$info holds the diagnostic (message, line, col, end_col, file, kind, found, expected, hint).
  • rpic_manifest() bundles now include a warnings array with structured compiler warnings for accepted-but-ignored input.
