Types

type Cursor

type Cursor struct {
	Token   lexer.Token
	Literal string
}

type Parser

type Parser struct {
	// contains filtered or unexported fields
}

Example

package main

import (
	"fmt"
	"strings"

	"github.com/itsubaki/qasm/pkg/lexer"
	"github.com/itsubaki/qasm/pkg/parser"
)

func main() {
	qasm := `
OPENQASM 3.0;
include "itsubaki/q.qasm";

qubit[2] q;
bit[2]   c;
reset    q;

h  q[0];
cx q[0], q[1];

measure q -> c;
`

	p := parser.New(lexer.New(strings.NewReader(qasm)))
	ast := p.Parse()
	fmt.Println(ast)

	if errs := p.Errors(); len(errs) != 0 {
		for _, err := range errs {
			fmt.Println(err)
		}
	}

}

Output:

OPENQASM 3.0;
include "itsubaki/q.qasm";
qubit[2] q;
bit[2] c;
reset q;
h q[0];
cx q[0], q[1];
measure q -> c;
