Description

HighlightStyle cannot express inline code font size, borders, radius, or padding. Add one inline_code_style(StyleRefinement) override for typography and box presentation, covering both font-size customization and outlined code spans. Supersedes #3639.

Unspecified properties inherit the resolved theme or explicit style. User overrides apply after surface-color adaptation, including on inverted surfaces. Existing inline_code(HighlightStyle) and with_inline_code(HighlightStyle) calls remain supported, and the public Component TextViewStyle fields are unchanged. Defaults retain the existing appearance: a 0.875 font-size ratio and no border.

Shaping, wrapping, painting, and table column measurement share font-size and inset resolution. Code and prose stay separate when their font sizes match, preventing code backgrounds and padding from extending into adjacent prose. Backgrounds and borders fade with streamed text.

English and Chinese documentation describe the supported properties. Line height remains paragraph-owned; margin, positioning, flex, explicit box dimensions, overflow, and interaction properties are not applied to inline code.

Example

use gpui_kit::{StyleRefinement, Styled as _, rems};
use gpui_kit::component::{ActiveTheme as _, text::TextView};

TextView::markdown("notes", "Run `cargo build` first.")
    .inline_code_style(
        StyleRefinement::default()
            .text_size(rems(1.))
            .px(rems(0.25))
            .border_1()
            .border_color(cx.theme().border),
    )

Public API

gpui-base

• TextViewStyle::with_inline_code_style(self, style: StyleRefinement) -> Self — Set explicit inline code typography and box refinements.
• TextViewStyle::inline_code_style(&self) -> &StyleRefinement — Read the explicit refinement.
• TextView::inline_code_style(self, style: StyleRefinement) -> Self — Refine inline code over the resolved style.

gpui-component

• text::TextView::inline_code_style(self, style: StyleRefinement) -> Self — Apply the same override through the Component facade.

Breaking Changes

None for existing consumers. Existing HighlightStyle APIs, imports, defaults, and public Component style fields remain compatible.

Validation

• cargo test -p gpui-base -p gpui-component --features gpui-component/test-support --lib text:: --locked — 391 Base and 69 Component tests passed.
• Tests cover equal-size code/prose separation, rem-based box measurement and wrapping at two zoom levels, style inheritance, inverted surfaces, invalid font sizes, and background/border fading.
• cargo clippy -p gpui-base -p gpui-component --features gpui-component/test-support --all-targets --locked -- --deny warnings — passed.
• cargo fmt --all --check, git diff --check, and whole-repository typos 1.40.0 — passed.
• The typo dictionary now accepts the correct Portuguese word atual, resolving the unrelated CI false positive.
