Paul Zuurbier submitted an update to the
numodel-bundle
package.
Version: 0.9.1 2026-09-07
License: lppl1.3c
Summary description: Numerical physics models with Forrester diagrams and
auto-sized plots
Announcement text:
------------------------------------------------------------------------
This release is numodel-plot only; numodel is version-synced with no
functional changes. It is also the first published release carrying
the 0.9.0 work: that archive was prepared but never published, so the
changes below reach users here.
Highlights
----------
* A scaled axis now presents its power of ten as an SI prefix on the
unit: "s (km)" instead of "s (10^3 m)", "E (TJ/kg)" instead of
"E (10^6 MJ/kg)", "m (Mg)" instead of "m (10^3 kg)". The fold
respects unit powers (10^6 m^2 -> km^2) and existing prefixes, and
falls back to the power-of-ten form whenever no engineering prefix
fits. The new setup key scale-format=exponent restores the previous
presentation globally.
* New setup key halo-color. The default halo-color=auto matches the
tick-label halo to the surrounding background at every \drawplot:
a tcolorbox's colback, a beamer colour theme's bg, the pagecolor
package's \thepagecolor, and white otherwise. Any other value pins
the halo to that colour.
Fixed
-----
* \qtyPlain produced wrong output on siunitx 3.5.0 and newer. siunitx
renamed the variable holding the current prefix-mode from
\l_siunitx_quantity_prefix_mode_tl -- a documented public variable
through v3.4.14 -- to \l_siunitx_quantity_prefix_mode_str, leaving
the old name declared but never assigned. Reading the stale name
resolved an empty mode and fell through to plain \qty, so every
scaled axis label silently gained a spurious "1": "t (1 ks)" instead
of "t (ks)". Nothing errored. The mode is now read from whichever
variable carries a value, so both siunitx generations work.
Under the hood
--------------
* \qtyPlain no longer patches siunitx internals. It is now built
entirely on siunitx's documented code-level interface, following the
investigation behind siunitx issue #864, which established that the
whole prefix-mode pipeline is already public. Axis labels are
unchanged; three edge cases the old override got wrong are fixed
(a mantissa of 1 behind a sign or comparator is no longer dropped,
a number carrying an uncertainty is passed through untouched, and
all three prefix-mode values now behave the same whether \qtyPlain
is called directly or reached through \edef).
* \pzuIfUnitNonEngTF derives its verdict from the net power of ten
siunitx extracts from the unit instead of from a hard-coded list of
prefix control sequences. Two units change verdict, both towards
scaling: \centi\metre\per\centi\second (the prefixes cancel) and
\centi\metre\cubed (cm^3 is 10^-6 m^3).
Packaging
---------
* The bundle now ships one README and one CHANGELOG, both at the
bundle root, on CTAN maintainer request. The former per-module
README/CHANGELOG pairs have been merged into them; module-specific
entries live under a per-module heading within each release.
Requirements
------------
* siunitx is now requested with a date of 2023-11-06 (v3.3.8). An
older siunitx produces a LaTeX warning rather than an error, but
scaled axis labels may come out subtly wrong.
See CHANGELOG.md for the full list.
