Maroto

A Maroto way to create PDFs. Maroto is inspired in Bootstrap and uses Gofpdf. Fast and simple.

Maroto definition: Brazilian expression, means an astute/clever/intelligent person.

You can write your PDFs like you are creating a site using Bootstrap. A Row may have many Cols, and a Col may have many components. Besides that, pages will be added when content may extrapolate the useful area. You can define a header which will be added always when a new page appear, in this case, a header may have many rows, lines or tablelist.

Installation

• With go get:

go get -u github.com/johnfercher/maroto

• With dep:

dep ensure -add github.com/johnfercher/maroto

Examples

In the PDFs folder there are the PDFs generated using Maroto, and in the examples folder there are subfolders with the code to generate the PDFs.
