Nadi Cairo plugin

Cairo is a 2D drawing library with various output formats. It is designed to be consistent across all those formats.

History

NADI IDE was initially written using GTK3 and the network diagram was drawn using cairo, which meant you could save the exact same diagram showin in the UI element into files as well. But due to complications related to Windows operating system, IDE was rewritten in iced (a rust native cross platform library). The old code from the GTK3 interface is available as this plugin so you can still generate network diagrams.

Installation

Follow the installation steps for a nadi plugin, which includes compiling the repository with cargo and copying the compiled plugin using nadi (which needs to be installed and inside PATH).

git clone https://github.com/Nadi-System/nadi-cairo
cd nadi-cairo
cargo build --release
nadi -i target/release/libnadi_cairo.so

Example

The following code, results into the image shown below:

net.load_str("a->b\nb->c\nc->d\nx->c\ny->b\nx->y")
net.cairo.network("example.svg", label="[{INDEX}] {NAME}")

Warning

1. As it was old code from the GTK version, this only works for tree graphs, not for other kinds of graph/network even if nadi officially supports any kind of directed network for analysis.
2. The reason we shifted away from GTK was because of complications with compiling for windows, as such, nadi-cairo is not tested in windows and mac. It works fine in Linux system with libcairo installed (which comes with libgtk3). The nadi book is also rendered in Linux, so if you want to use it on other OS, please find out how to download and compile with cairo C library.
