This gets us ever closer to the goals of the elusive (and presumably abandoned?) Grok project [1].<p>I'd love to see syntax highlighters (like Pygments), editors and IDEs, autocompletion providers, debuggers, and all other language-related tooling consume a standardized canonical "language description format". Making a new language? Bam! It's automatically supported by Visual Studio, Eclipse, Emacs, vim, Sublime Text, gdb, Pygments, the list goes on.<p>The extension capabilities are also awesome. Let's say I have a huge project and, at a certain level of abstraction, users aren't allowed to use fprintf(stderr, ...), they need to use LOG(...). It would be great to have a file in your project that can tell your environment to give you the "red squigglies" and autofix information for such situations.<p><a href="http://bsumm.net/2012/08/11/steve-yegge-and-grok.html" rel="nofollow">http://bsumm.net/2012/08/11/steve-yegge-and-grok.html</a>
