A node.js command line interface and npm package for the WebVTT JavaScript parser.

This is a simple command line wrapper around the WebVTT JavaScript parser. It was written to enable faster development of a WebVTT test suite. Th e npm module includes the WebVTT parser, and allows one to pass file(s) in order to be validated.

Installation

$ npm install webvtt

installs the webvtt shell command.

Examples

Validate a single file, printing error messages, if any:

$ webvtt file.vtt

Validate two files, printing error messages, if any:

$ webvtt file1.vtt file2.vtt

Validate a single file, don't print error messages:

$ webvtt -s file.vtt

Synopsis

$ webvtt
Usage: webvtt [options] <file...>

Options:

  -h, --help     output usage information
  -V, --version  output the version number
  -s, --silent   don't print errors messages

Output

The webvtt command will exit with an error code of 0 (no errors) or 1 (errors), depending on the file(s) given as input. If run in silent mode (-s or --silent), no output will be printed, otherwise each error encountered in a file will be printed in the following format:

filename:linenumber.column: message

For example:

$ webvtt file.vtt
file.vtt:1.0: No valid signature. (File needs to start with "WEBVTT".)
