这是代码,我使用 gccgo 进行编译。这是基于图形的组织者。我不需要关于图算法的建议。
package element
import (
"fmt"
"strings"
"io"
"strconv"
)
type Node struct {
id int
name string
props map[string]string
links map[string][]*Node
}
var names = make(map[string]int , 8)
var nodes = make(map[string][]*Node , 8)
//========functions================
func new_node(Id int) *Node {
return &Node( Id, " ", nil, nil)
}
func getNode_byId(nodes []*Node, id int) *Node {
for _, node := range nodes{
if node.id == id {
return node
}
}
return nil
}
func addNode(store string, node *Node) {
nodes[store] = append(nodes[store], node)
}
func addLinkToNode(node, link *Node, property string) {
node.links[property] = append(node.links[property], link)
}
func nodeFromString(str string, typ string) {
lines := strings.Split(str, "\n")
lcount := len(lines)
if lines[0] == "[begin]" && lines[lcount] == "[end]" {
fmt.Println("common dude! something wrong with ur string")
return
}
fields := strings.Fields(lines[1])
id , _ := strconv.Atoi(fields[1])
nod := getNode_byId(nodes[typ], id )
if nod == nil { nod = new_node(id) }
addNode(typ, nod)
nod.name = typ
lines = lines[2:]
ind :=0
for index, line := range lines {
fields := strings.Fields(line)
if field := fields[0]; field[0] != '-' {
ind = index
break
}
nod.props[fields[0]] = fields[1]
}
lines = lines[ind:]
for index, line := range lines {
if line[0]!= '+' {
ind = index
break
}
pivot := strings.Index(line, " ")
field := line[0:pivot]
fields := strings.Split(line[pivot:], ",")
这是我得到的错误,我尽力了,但我无法解决。
$ gccgo elements.go
elements.go:23:19: error: expected ‘)’
elements.go:23:34: error: expected ‘;’ or ‘}’ or newline
elements.go:23:2: error: too many values in return statement
elements.go:91:4: error: value computed is not used
我不明白在哪里需要使用分号以及为什么。
