About

This is the Go implementation of simple-graph.

Usage

Installation

• SQLite, version 3.31.0 or higher; get the latest source or precompiled binaries from the SQLite Download Page
• Go
• go-sqlite3

  go get github.com/mattn/go-sqlite3

• go-graphviz for visualizations

  go get github.com/goccy/go-graphviz

• Optionally, or if the statements in the [originating sql folder (https://github.com/dpapathanasiou/simple-graph/tree/main/sql) change, run the constants generation script to rebuild the constants.go file

  ./generate-constants.sh

Basic Functions

The database package provides convenience functions for atomic transactions to add, delete, connect, and search for nodes.

There are also visualization functions to convert search and traversal outputs into dot format for conversion images.

Testing

There are unit tests in the simplegraph package covering each of the basic functions.

Make sure to use the json1 tags when running them:

cd simplegraph
go test -tags json1

If you have the correct version of SQLite installed, the tests should all pass:

PASS
ok  	github.com/dpapathanasiou/simple-graph/go/simplegraph	0.067s

TODO

• Marshall/unmarshal using json (or gabs, etc.) for injecting "id" fields, and merging bodies in update and upsert instead of the full replacement that happens now
