dot-graph

dot parser in Rust implemented with FFI to Graphviz cgraph library.

Prerequisites

dot-graph parses a dot format file using C bindings to Graphviz (v7.0.6).

The system environment should be able to find and include the following header files.

```C

include

include

```

Option 1. Installing Graphviz from Package Manager

Coming from Linux, console $ sudo apt install graphviz-dev

And coming from vanilla Ubuntu, you may want to install these too. console $ sudo apt install build-essentials cmake $ sudo apt install clang

Coming from Mac, console $ brew install graphviz

And coming from Apple Silicon Mac, and add an environment variable, shell export CPATH=/opt/homebrew/include

Option 2. Building Graphviz from Source

Or, try building from the source code yourself following the guide.

Usage

```rust use dot_graph::prelude::*;

fn main() -> Result<(), DotGraphError> { /* parse from file / let graph = parser::parse_from_file(/ path */)?; let mut stdout = std::io::stdout(); graph.to_dot(&mut stdout)?;

/* parse from memory / let graph = parser::parse_from_memory(/ dot file contents in memory */)?; let mut stdout = std::io::stdout(); graph.to_dot(&mut stdout)?;

Ok(()) } ```
