# ABNF
A parser for ABNF based on nom 7.
## Example
The following code
```rust
use abnf::rulelist;
// Note: mind the trailing newline!
match rulelist("a = b / c\nc = *(d e)\n") {
Ok(rules) => println!("{:#?}", rules),
Err(error) => eprintln!("{}", error),
}
```
outputs
```rust
[
Rule {
name: "a",
node: Alternatives(
[
Rulename(
"b",
),
Rulename(
"c",
),
],
),
kind: Basic,
},
Rule {
name: "c",
node: Repetition {
repeat: Variable {
min: None,
max: None,
},
node: Group(
Concatenation(
[
Rulename(
"d",
),
Rulename(
"e",
),
],
),
),
},
kind: Basic,
},
]
```
You can also use the provided example to parse and `Debug`-print any ABNF file.
```sh
cargo run --example=example examples/assets/abnf.abnf
