A validator for the AMP HTML format.
This is a very first release, rough on the edges. Fasten your seatbelts.
Prerequisite: Linux Ubuntu 14 or similar
Install these packages using apt-get:
- npm
- nodejs
- openjdk-7-jre
- protobuf-compiler
- python-protobuf
- python2.7
Then, run build.py. It creates codegen/validate, a script which
can print AMP HTML validation errors to the console.
$ codegen/validate
usage: validate <file.html>
$ codegen/validate testdata/minimum_valid_amp.html
PASS
$ touch empty.html
$ codegen/validate empty.html
