Creating books with Gitbook
I'm currently tasked with the revision of some lecture material for basic HTML, CSS and PHP studies, so I thought I should give gitbook a try.
It's a super sweet generator for creating an interactive website, a pdf and even epub from a loosely structured bunch of MarkDown files. You can imagine I love that.
Since I started playing with this locally, I didn't have my content in a repository yet, but just in a folder and I simply didn't get a hint in the usage instructions and got the following error:
Starting build ...
TypeError: Cannot call method 'replace' of undefined
at Object.titleCase (/usr/lib/node_modules/gitbook/bin/utils.js:52:16)
at _fulfilled (/usr/lib/node_modules/gitbook/node_modules/q/q.js:787:54)

at flush (/usr/lib/node_modules/gitbook/node_modules/q/q.js:108:17)
at process._tickCallback (node.js:415:13)
Which was just me trying to write something else but the line below:
$ gitbook build -g jonathan/topic-book institution-webcourse/
After that everything worked fine. Since gitbook expects the source to be a repository it demands the author and title divided by the slash, like on github.
