Re: Using Emacs nXML mode to validate XHTML5 using the v.Nu schemas: support for HTTP-based schema URI?

[Graham Hannington]

> Do you know how/when/where those missing files get generated?

How: yes.

By the v.Nu Python build script, build.py:

https://github.com/validator/validator/blob/master/build/build.py

When: no.

At least, not precisely. Imprecisely, the bleeding obvious ;-): whenever a 
v.Nu developer, or anyone else who clones the repo, decides to build v.Nu 
from source.

Certainly, whenever the v.Nu developers decide it's time for a new 
release:

https://github.com/validator/validator/releases

If that's not what you meant by "when": for details on when, during the 
build process, the missing files are generated, see the source of 
build.py.

Where: that depends on what you mean by "where", and probably not for the 
facetious reasons you're imagining ;-).

All of the schema files are delivered in the .jar (or .war; but I've been 
using the .jar) in one "flat" directory (with no subdirectories):

nu/validator/localentities/files/

That directory contains a file named entitymap. Each line of that file 
maps a file name in that directory to a URI. Here is an example line for a 
schema file:

http://s.validator.nu/html5/block.rnc  schema_html5_block_rnc

The extension-less file names are an underscore-delimited concatenation of 
the directory path, file name, and extension of the corresponding source 
file from the repo (or a similar-looking confection, for files that are 
created during the build).

So the answer to "where" has more to do with those internal v.Nu schema 
URIs than the actual "physical" location (directory path) of the files in 
the generated .jar.

In terms of those URIs, the missing files are generated in the html5 
directory.

One file, rdf.rnc is moved from the repo .drivers directory to the "build 
only" rdf directory.

There are other differences, too.

For more details, you can perform your own comparison by following the 
steps in the readme at:

https://github.com/unsoup/validator#comparing-the-source-and-distributed-schemas

Or ask me, and I'll send you a detailed report from, say, WinMerge (what I 
typically use), or your free diff tool of choice.
