Built-in live command

[denisdefreyne]

The guard-nanoc way of auto-recompiling a Nanoc site has some drawbacks:

• Needs configuration: guard-nanoc needs a Guardfile whose configuration is the same pretty much all the time: watch nanoc.yaml/config.yaml, Rules, and content+layouts+lib. This configuration is redundant.

• Breaks easily: Because guard-nanoc is a separate project that uses internal APIs of Nanoc, it tends to break after a Nanoc release.

• Filesystem only: guard-nanoc can only listen to changes on the local file system.

A nanoc live command could solve these problems. In order for a nanoc live command to be full-fledged, it needs the following:

• watcher
• web server
• notifications
• autoreload
• support for Windows (i.e. no fork)

Future work includes analysing incoming changes and bypassing the outdatedness checker when possible.
