Generate positions for values in JSON and JSON5 strings
npm install @mischnic/json-sourcemapGenerate positions for values in JSON and JSON5 strings.
Inspired by and mostly API-compatible with https://github.com/epoberezkin/json-source-map.
``ts
type Position = {
line: number;
column: number;
pos: number;
};
type Mapping =
| {
value: Position;
valueEnd: Position;
}
| {
value: Position;
valueEnd: Position;
key?: Position;
keyEnd?: Position;
};
export function parse(
json: string,
reviver?: (key: any, value: any) => any,
options?: {
tabWidth?: number;
dialect?: "JSON5" | "JSON";
}
): {
data: any;
pointers: Record
};
`
The default tabWidth is 4.
The valueEnd and keyEnd positions are exclusive. line, column and pos` are 0-based.
