## Install
[npm][]:
```sh
npm install micromark-factory-space
```
## Use
```js
import {factorySpace} from 'micromark-factory-space'
import {codes} from 'micromark-util-symbol/codes'
import {types} from 'micromark-util-symbol/types'
// A micromark tokenizer that uses the factory:
/** @type {Tokenizer} */
function tokenizeCodeFenced(effects, ok, nok) {
return start
// …
/** @type {State} */
function info(code) {
if (code === codes.eof || markdownLineEndingOrSpace(code)) {
effects.exit(types.chunkString)
effects.exit(types.codeFencedFenceInfo)
return factorySpace(effects, infoAfter, types.whitespace)(code)
}
if (code === codes.graveAccent && code === marker) return nok(code)
effects.consume(code)
return info
}
// …
}
```
## API
This module exports the following identifiers: `factorySpace`.
There is no default export.
### `factorySpace(…)`
Note that there is no `nok` parameter:
* spaces in markdown are often optional, in which case this factory can be
used and `ok` will be switched to whether spaces were found or not,
* One space character can be detected with
[markdownSpace(code)][markdown-space] right before using `factorySpace`
###### Parameters
* `effects` (`Effects`) — Context
* `ok` (`State`) — State switched to when successful
* `type` (`string`) — Token type for whole (`' \t'`)
* `max` (`number`, default: `Infinity`) — Max size of whitespace
###### Returns
`State`.
###### Examples
Where `␉` represents a tab (plus how much it expands) and `␠` represents a
single space.
```markdown
␠␠␠␠
␉␠
```
