No. The v.Nu linter is the first Atom linter to use v.Nu.

If you want to use
xmllint to validate (X)HTML, you might be interested in the unsoup/validator GitHub repo.
The v.Nu linter is a client of the v.Nu web service and a linter provider for the Atom Linter. The v.Nu linter is just glue code. The real work is done by v.Nu and Linter.
The URL might be a localhost URL, referring to an instance of v.Nu installed on your computer.
You do not need to install v.Nu on your computer to use the v.Nu linter. You just need a v.Nu URL.
However, there are reasons to install v.Nu on your computer. For similar reasons, you might choose to install v.Nu on a computer that you share with other users on an intranet.
The v.Nu linter communicates with v.Nu via HTTP(S). Installing v.Nu on your computer means you can specify a localhost URL for v.Nu, such as
http://localhost:8888, bypassing network interface hardware.
You can configure the v.Nu linter to lint either as you type ("on the fly") or only when you save. By default, the v.Nu linter lints on the fly: it sends the current document to v.Nu every 0.3 seconds while you are typing. You can set this interval in the Linter package settings. If you routinely stream high-definition video across your network, this traffic might not be an issue. Otherwise, it's worth considering.
Linter triggers its providers only while you are typing. To see what this means in practice - in terms of frequency of Ajax requests from the v.Nu linter to v.Nu - use the Atom developer tools to monitor network activity.
If you choose not to lint as you type - to lint only when you save - then performance is less of an issue.
A localhost URL means your data stays on your computer.
Is it cool (polite) to post every 0.3 seconds to a public v.Nu that you don't pay for?

Decide whether to install v.Nu on your computer or to use an existing v.Nu instance.
To help you decide, see "Reasons..." (above).
To install v.Nu on your computer, continue to the next step. Otherwise, skip to step 10.
If you do not have Java on your computer, install it.
v.Nu is a Java application. It requires a Java runtime.
For more details on v.Nu installation requirements, such as the minimum Java version required, see the v.Nu documentation.
To check your Java version, enter
java -version at a command prompt.
Enter the following
java command to start v.Nu as a standalone web server:
java -Xss512k -cp vnu.jar nu.validator.servlet.Main 8888
-Xss512ksets the thread stack size. You might not need this parameter. But if you omit it, you might get a stack overflow error.
8888is the port number on which v.Nu listens. Feel free to specify a different port.
For more information on installing v.Nu, see the v.Nu documentation.
http://localhost:8888) in a browser.
http://localhost:8888, point the v.Nu linter at the correct URL: in Atom, select File ▶ Settings ▶ Packages, select
linter-vnu, and then enter the URL.
To validate the current document as HTML5, give it the file extension
.html or one of the other file extensions that belong to the HTML grammar.
To validate the current document as XHTML5 (the XML serialization of HTML5), the document must have the file extension
examples directory of this package contains files to play with.
Perhaps. Given time. If there's interest from users.
Add a "v.Nu start command" setting. If the v.Nu URL is a
localhost URL, and that URL is not responding to requests, then issue the start command.
If possible, exploit the
schema ("bring your own schema") parameter of the v.Nu web service to validate languages other than HTML5 and XHTML5. (Including, but not limited to, languages such as SVG and MathML that v.Nu already validates inline in (X)HTML.) That would open up a universe of validation possibilities.
Raise with the Atom developers the idea of defining XHTML as a grammar that is distinct from HTML.
Move and expand some topics from this readme to a wiki.
"The v.Nu linter" is an abbreviation for "An Atom linter provider for v.Nu, developed by Graham Hannington at Fundi Software".
"v.Nu linter" is, arguably, both a tautology and a lie. v.Nu might be characterized as a linter (cue the punditry on linter versus validator versus document conformance checker ), but the v.Nu linter is not v.Nu. And the v.Nu linter is not, by itself, a linter.
The use of a leading definite article - the v.Nu linter - is also questionable. See the disclaimer.

Thanks to the developers of v.Nu, Atom, and Atom Linter. Your hard work made developing the v.Nu linter easy.
Good catch. Let us know what about this package looks wrong to you, and we'll investigate right away.
