# Interface fonts
|
|
|
|
SolidCraft bundles IBM Plex Sans as its default interface font on desktop and web.
|
|
The unmodified variable font provides regular (400), medium (500), semibold (600)
|
|
and bold (700) faces. Titles and selected labels use semibold; compass letters
|
|
and the primary OK action use bold. Selection fields and status messages use
|
|
medium. Numeric fields and sketch dimensions use IBM Plex Mono Regular.
|
|
|
|
Both fonts are licensed under the SIL Open Font License 1.1. Their licence texts
|
|
are in `assets/fonts/ibm-plex-sans/OFL.txt` and
|
|
`assets/fonts/ibm-plex-mono/OFL.txt`; provenance is recorded in
|
|
[ATTRIBUTION.md](../ATTRIBUTION.md).
|
|
|
|
The `ui_font` preference puts the chosen font first in every sans family,
|
|
including the three weighted families. A chosen static font retains its own
|
|
weight; SolidCraft does not simulate bold by drawing text twice. Clearing the
|
|
preference restores Plex. Monospace fields keep Plex Mono.
|
|
|
|
Egui's symbol and emoji fallbacks remain available. Desktop also appends the
|
|
available Japanese/Chinese, Hangul and Thai system fonts to every family, ordered
|
|
for the selected language. The web app installs Plex at startup and adds its
|
|
bundled Japanese font asynchronously when needed, preserving the interface faces
|
|
and any font preference.
|
|
|
|
## Type scale and metrics
|
|
|
|
Text sizes come from `theme::Tokens`, with identical values in the light and dark
|
|
palettes in `assets/styles/ui/palettes.rs`. The compact scale runs from
|
|
`font_badge` (9.5 pt) through `font_heading` (14 pt). Special roles preserve the
|
|
existing designs: `font_triad` (8), `font_compass` (13.5), `font_subtitle` (15),
|
|
`font_intro` (16), `font_article_heading` (17), `font_title` (22), and
|
|
`font_display` (26). Scaled labels derive from these tokens. Weight helpers in
|
|
`fonts.rs` choose the family independently of size.
|
|
|
|
Dense forms also use tokens for control height/radius, label width, row gap,
|
|
header/footer/card dimensions, icons, text insets, checkbox and action heights,
|
|
and section letter spacing. Existing `space_*` tokens supply shared padding.
|
|
The `font_literals_tests` source guard scans production Rust, including the
|
|
viewport icon sources, and rejects numeric font sizes, private font families
|
|
outside `fonts.rs`, and direct dense-form spacing literals. Its small per-file
|
|
allowance table documents graphic spinner diameters; it permits no text sizes.
|
|
Run it with `cargo test -p solidcraft-ui-egui --lib font_literals_tests`.
