Install: `npm install @mantine/core@9.7.1 @mantine/hooks@9.7.1`

## Version and compatibility

Pinned Mantine Core 9.7.1 requires React and React DOM `^19.2.0` and matching `@mantine/hooks@9.7.1`, from the installed npm package's peerDependencies. Do not force it into React 18 or another incompatible version. Explain upgrade impact and agree on a plan with the project owner; do not hide conflicts with --force/--legacy-peer-deps. The native Provider enables `theme.respectReducedMotion` and uses `forceColorScheme` for light/dark.

## Use case

Display progress on a semicircle.

## Native props used by this example

These props are extracted from the local typechecked JSX and grouped by their owning native component. This is not an exhaustive prop list; see pinned source signatures and inheritance below.

| Component prop | Explanation |
| --- | --- |
| `SemiCircleProgress.value` | Controlled value; the native type defines its shape. |
| `SemiCircleProgress.label` | Visible label or component-specific label content. |

## Interaction and state checks

Current scenarios: Default. Check actual behavior after selecting supported disabled/error/read-only scenarios; components without those native states do not receive invented universal props. Verify keyboard focus and exits, then connect changed values through the native callback signature.

## Business integration boundary

Demo content/state is local, without server persistence, authorization or fetching. A static display component is not a completed business workflow.

## Host setup

Install pinned @mantine/core and @mantine/hooks, import @mantine/core/styles.css at the entry and use MantineProvider. The example's theme/variant are JGuang-authored host props, not universal native component APIs; forceColorScheme synchronizes the app theme. Native implementation source is a reading reference: use npm exports rather than copying internal engines. This batch covers Core, not dates/charts/forms extension packages. Detailed upstream prose remains English.


## Runnable usage

```tsx
import { useState } from 'react';
import * as M from '@mantine/core';
import '@mantine/core/styles.css';


function ComponentPreview({ variant = 'Default' }: { variant?: string }) {
const [value, setValue] = useState(35);
return <M.SemiCircleProgress value={65} label="65%" />;
}
export default function Example({ variant = 'Default', theme = 'light' }: { variant?: string; theme?: 'light' | 'dark' }) {
return <M.MantineProvider forceColorScheme={theme} theme={{ respectReducedMotion: true }}><ComponentPreview variant={variant} /></M.MantineProvider>;
}

```


## Preview states

Default

The example uses the native Mantine API. For supported input demos, change the local variant to Disabled, Invalid or Read only; these are example labels, not new component props. Keep the documented data, controlled values, stores and compound children when adapting the example.



## Usage



## Change empty segment color

Use `emptySegmentColor` prop to change color of empty segment,
it accepts key of `theme.colors` or any valid CSS color value:



## Change label position

By default, the label is displayed at the bottom of the component,
you can change its position to `center` by using `labelPosition` prop:



## Filled segment transition

By default, transitions are disabled, to enable them, set `transitionDuration` prop
to a number of milliseconds:




## Source-backed parameter reference

Implementation signatures and types are generated from the pinned local source. Optional props, native inherited types, union branches and never exclusions are preserved. A forwardRef implementation's ref is a React reference, not an additional business prop.


```ts
SemiCircleProgress(_props)

```ts
export type SemiCircleProgressStylesNames =
  | 'root'
  | 'svg'
  | 'emptySegment'
  | 'filledSegment'

export type SemiCircleProgressCssVariables = {
  root:

    | '--scp-empty-segment-color'
    | '--scp-rotation'
    | '--scp-transition-duration'
    | '--scp-thickness';
};

export interface SemiCircleProgressProps
  extends BoxProps, StylesApiProps<SemiCircleProgressFactory>, ElementProps<'div'> {
  /** Progress value from `0` to `100` */
  value: number;

  /** Width of the component and diameter of the full circle in px. The visible SVG height will be size/2 @default 200 */
  size?: number;

  /** Stroke width of the circle segments in px @default 12 */
  thickness?: number;

  /** Transition duration for the filled segment progress changes in ms. Does not affect color transitions @default 0 */
  transitionDuration?: number;

  /** Label rendered inside the circle */
  label?: React.ReactNode;

  /** Label position relative to the circle center @default 'bottom' */
  labelPosition?: 'center' | 'bottom';
}

export type SemiCircleProgressFactory = Factory<{
  props: SemiCircleProgressProps;
  ref: HTMLDivElement;
  stylesNames: SemiCircleProgressStylesNames;
  vars: SemiCircleProgressCssVariables;
}>;

export type Mod = Record<string, any> | string;

export type BoxMod = Mod | Mod[] | BoxMod[];

export interface BoxProps extends MantineStyleProps {
  /** Class added to the root element, if applicable */
  className?: string | undefined;

  /** Inline style added to root component element, can subscribe to theme defined on MantineProvider */
  style?: MantineStyleProp;

  /** CSS variables defined on root component element */
  __vars?: CssVarsProp;

  /** `size` property passed down the HTML element */
  __size?: string;

export type ElementProps<
  ElementType extends React.ElementType,

export type MantineStyleProp = MantineStyle | MantineStyle[] | MantineStyleProp[] | undefined;

export type CssVariable = `--${string}`;

export type CssVariables<Variable extends string = CssVariable> = Partial<Record<Variable, string>>;

export type CssVars<Variable extends string = CssVariable> =

  | ((theme: MantineTheme) => CssVariables<Variable>)
  | CssVars<Variable>[];

export type CssVarsProp<Variable extends string = CssVariable> =
  | CssVars<Variable>
  | CssVars<Variable>[];
```


### Native and external types

External types remain defined by React or native dependencies, not manually expanded into guessed props. The installed version's TypeScript definitions are authoritative.


```ts
Factory<{
  props: SemiCircleProgressProps;
  ref: HTMLDivElement;
  stylesNames: SemiCircleProgressStylesNames;
  vars: SemiCircleProgressCssVariables;
}>
MantineStyleProps
React.CSSProperties
MantineTheme
Partial<Record<Variable, string>>
Record<Variable, string>
Variable
MantineBreakpoint
Record<string, any>
StylesApiProps<SemiCircleProgressFactory>
React.ElementType
Omit<React.ComponentProps<ElementType>, 'style' | PropsToOmit>
React.ComponentProps<ElementType>
ElementType
PropsToOmit
MantineColor
React.ReactNode
HTMLDivElement
```
