Heading for a week of R&R and have no access to internet or cellular networks.
Was wondering if the entire documentation on Node-Red was available in PDF format?
Failing that, any suggestion on what program to use to download the Doc site for off-line access?
You might look at wget - it is a command line tool but it can grab an entire website and convert all the links to local ones.
You can clone the website repository to your local machine using
git clone https://github.com/node-red/node-red.github.io.git
That will create a directory called
node-red.github.io that contains all the source of the website.
That'll get you the docs in their raw markdown format - fairly readable plain text.
If you wanted to go above and beyond, you can install Jekyll and then...
cd node-red.github.io.git jekyll serve
That will build the documentation and start a webserver at http://127.0.0.1:4000 - open that in a browser and you'll have the node-red website locally.
Word of warning - to install jekyll you'll need to have a working install of ruby and depending on your OS etc, that may just be one rabbit hole too many.
On that same principle though, you can also grab the cookbook:
git clone https://github.com/node-red/cookbook.nodered.org.git
If you need a more readable format, rather than going down the Ruby/Jekyll rabbit hole, you can grab a copy of Typora instead which gives you a fairly well formatted WYSIWYG format. I sometimes use Typora to create new entries on my blog (which uses Hugo rather than Jekyll but otherwise uses a similar approach).
