This package uses bookdown to turn plain text files into a songbook. Since it's using bookdown, a plethora of output formats are are available: beautiful html sites, pdf documents, docx files and epub just to name a few of them. Check the bookdown documentation for more information on this.
The key concept behind this package is the following: You copy and paste plain text lyrics (with or without guitar chord information) from a site like https://www.ultimate-guitar.com/ or similar1 and save it as "songname.txt" within an R-Project. You then add some metadata to this song using a yaml-style header. The songbook package then uses these textfiles to generate intermediate files that in turn will be used by bookdown to create a songbook.
Just as knitr leverages pandoc (see image below), songbookdown leverages bookdown and the rest of the tools to build an awesome songbook.
1 Remember to mention the source!
The package offers a way to specify typical song related metadata in a simple and structured way without thinking about how this metadata is used and displayed in the output. Such song related data can be title of the song, artist, tempo etc.
The package is not on CRAN, so to install songbookdown use devtools or remotes and install it from github like so:
devtools::install_github("ratnanil/songbookdown")
This package is still under development. Things will most likely break, contact me if you are interested in using it, then I will try and be more careful :-)
