Inability to prevent folders from being watched

[tlhuillier]

In some projects, I like to have the documentation inside the project (next to the source code), as well as the built output of the documentation (let say you want to publish your doc using Github pages for example, you could build it inside your project).

A project like this is structured like so:

.
├── components/
├── assets/
├── translations/
├── doc/
│   ├── _config.yml/
│   ├── intro.md
│   └── ...
├── build/
│   ├── doc/
│   └── ...
│── package.json
│── webpack.config.js
└── ...

Then I would build or watch the stylemark doc like so:
stylemark -i . -o ./build/doc -c ./doc/_config.yml -w -b

Note that for such projects, the documentation lives inside source code as well as in some dedicated markdown files (and that's why stylemark input is set to .).

But when watching for file changes, the filewatcher sees file changes when stylemark update the content of /build/doc/ — and thus triggering an infinite loop, the doc getting built over and over again.

It would be great to have a proper way to prevent some folders from being watched to prevent such problems.
