Which one works well? I'm more concerned about syntax highlighting and line numbering (in some cases). Support for custom fonts.
If you are an emacs user, probably you have heard about org-mode (http://orgmode.org/).
With its new export-backend, you write your text in org-mode (very similar to markdown) and then you can export to (almost) whatever you want.
Have a look at this opensource book about Operating Systems, it is written with org-mode: https://github.com/gwolf/sistop
