D bindings for igraph library

igraph-d

WIP

This is the repository for D bindings of igraph library for the network analysis. It is based on igraph C API and ImportC functionality.

Currently only examples from Tutorial were tested. More examples are coming.

Building

I recommend to build both C and D versions, to compare both results.

C building

To build C example run in the terminal (with assumption, that the igraph library was installed in /usr path):

cc igraph_test.c -I/usr/include/igraph -L/usr/lib -ligraph -o igraph_test

D building

At first you need to prepare igraph_lib.c file, where you need to include required header files:

#include <path_to_the_lib/igraph.h>

1. Manual preprocessing

You can preprocess file to eliminate macros manually (don't forget to add importc.h):

clang -E igraph_lib.c -o igraph_lib.i -include  /usr/include/dlang/ldc/importc.h

Compile with D compiler (which supports ImportC):

ldc2 igraph_test.d ./igraph_lib.i -L/usr/lib/libigraph.so

2. Auto preprocessing

In later versions of D compilers (at least DMD 104.0, LDC 1.34), you can ask the compiler to do all job:

ldc2 igraph_test.d ./igraph_lib.c -L/use/lib/libigraph.so

Tested

• macOS (M1)
• Linux
• Windows

Todo

• Inline C macros
• Make code more iDiomatic
• Prepare examples from Tutorial
• Prepare Simple examples from C repository
