* Parse spaces and tabs.
|
|
*
|
|
* 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 line ending or space can be detected with `markdownSpace(code)` right
|
|
* before using `factorySpace`
|
|
*
|
|
* ###### Examples
|
|
*
|
|
* Where `␉` represents a tab (plus how much it expands) and `␠` represents a
|
|
* single space.
|
|
*
|
|
* ```markdown
|
|
* ␉
|
|
* ␠␠␠␠
|
|
* ␉␠
|
|
* ```
|
|
*
|
|
* @param {Effects} effects
|
|
* Context.
|
|
* @param {State} ok
|
|
* State switched to when successful.
|
|
* @param {TokenType} type
|
|
* Type (`' \t'`).
|
|
* @param {number | undefined} [max=Infinity]
|
|
* Max (exclusive).
|
|
* @returns
|
|
* Start state.
