## What is this?
|
|
|
|
This package is a utility that takes any [unist][] (whether mdast, hast, etc)
|
|
node, position, or point, and serializes its positional info.
|
|
|
|
## When should I use this?
|
|
|
|
This utility is useful to display where something occurred in the original
|
|
document, in one standard way, for humans.
|
|
For example, when throwing errors or warning messages about something.
|
|
|
|
## Install
|
|
|
|
This package is [ESM only][esm].
|
|
In Node.js (version 16+), install with [npm][]:
|
|
|
|
```sh
|
|
npm install unist-util-stringify-position
|
|
```
|
|
|
|
In Deno with [`esm.sh`][esmsh]:
|
|
|
|
```js
|
|
import {stringifyPosition} from 'https://esm.sh/unist-util-stringify-position@4'
|
|
```
|
|
|
|
In browsers with [`esm.sh`][esmsh]:
|
|
|
|
```html
|
|
<script type="module">
|
|
import {stringifyPosition} from 'https://esm.sh/unist-util-stringify-position@4?bundle'
|
|
</script>
|
|
```
|
|
|
|
## Use
|
|
|
|
```js
|
|
import {stringifyPosition} from 'unist-util-stringify-position'
|
|
|
|
stringifyPosition({line: 2, column: 3}) // => '2:3' (point)
|
|
stringifyPosition({start: {line: 2}, end: {line: 3}}) // => '2:1-3:1' (position)
|
|
stringifyPosition({
|
|
type: 'text',
|
|
value: '!',
|
|
position: {
|
|
start: {line: 5, column: 11},
|
|
end: {line: 5, column: 12}
|
|
}
|
|
}) // => '5:11-5:12' (node)
|
|
```
|
|
|
|
## API
|
|
|
|
This package exports the identifier [`stringifyPosition`][stringifyposition].
|
|
There is no default export.
|
|
|
|
### `stringifyPosition(node|position|point)`
|
|
|
|
Serialize the positional info of a point, position (start and end points), or
|
|
node.
|
|
|
|
###### Parameters
|
|
|
|
* `node` ([`Node`][node])
|
|
— node whose `position` fields to serialize
|
|
* `position` ([`Position`][position])
|
|
— position whose `start` and `end` points to serialize
|
|
* `point` ([`Point`][point])
|
|
— point whose `line` and `column` fields to serialize
|
|
|
|
###### Returns
|
|
|
|
Pretty printed positional info of a node (`string`).
|
|
|
|
In the format of a range `ls:cs-le:ce` (when given `node` or `position`) or a
|
|
point `l:c` (when given `point`), where `l` stands for line, `c` for column, `s`
|
|
for `start`, and `e` for end.
|
|
An empty string (`''`) is returned if the given value is neither `node`,
|
|
`position`, nor `point`.
|
|
|
|
## Types
|
|
|
|
This package is fully typed with [TypeScript][].
|
|
It exports no additional types.
|
|
|
|
## Compatibility
|
|
|
|
Projects maintained by the unified collective are compatible with maintained
|
|
versions of Node.js.
|
|
|
|
When we cut a new major release, we drop support for unmaintained versions of
|
|
Node.
|
|
This means we try to keep the current release line,
|
|
`unist-util-stringify-position@^4`, compatible with Node.js 16.
|
|
|
|
## Security
|
|
|
|
This project is safe.
