Package Exports

remark-lint-maximum-line-length

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (remark-lint-maximum-line-length) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

When configured with 80.

In

This line is simply not tooooooooooooooooooooooooooooooooooooooooooooooooooooooo
long.

Just like thiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiis one.

And this one is also very wrong: because the link starts aaaaaaafter the column: <http://line.com>

<http://this-long-url-with-a-long-domain-is-invalid.co.uk/a-long-path?query=variables> and such.

Out

4:86: Line must be at most 80 characters
6:99: Line must be at most 80 characters
8:97: Line must be at most 80 characters

`valid.md`

In

This line is simply not toooooooooooooooooooooooooooooooooooooooooooo
long.

This is also fine: <http://this-long-url-with-a-long-domain.co.uk/a-long-path?query=variables>

<http://this-link-is-fine.com>

[foo](http://this-long-url-with-a-long-domain-is-valid.co.uk/a-long-path?query=variables)

<http://this-long-url-with-a-long-domain-is-valid.co.uk/a-long-path?query=variables>

![foo](http://this-long-url-with-a-long-domain-is-valid.co.uk/a-long-path?query=variables)

| An | exception | is | line | length | in | long | tables | because | those | can’t | just |
| -- | --------- | -- | ---- | ------ | -- | ---- | ------ | ------- | ----- | ----- | ---- |
| be | helped    |    |      |        |    |      |        |         |       |       | .    |

The following is also fine, because there is no white-space.

<http://this-long-url-with-a-long-domain-is-invalid.co.uk/a-long-path?query=variables>.

In addition, definitions are also fine:

[foo]: <http://this-long-url-with-a-long-domain-is-invalid.co.uk/a-long-path?query=variables>

Out

No messages.
