[go-nuts] weird thing happened to string concatenation on win7 OS

package main

import (
"fmt"
"bufio"
"io"
"os"
"regexp"
)

func main() {
configFile, configErr := os.Open(".\\config.ini")
properties := make(map[string]string)
reader := bufio.NewReader(configFile)
matcher, _ := regexp.Compile("(^\\w+)(\\s*=\\s*)(.*)")
var content string
var err error
for {
content, err = reader.ReadString('\n')
kv := matcher.FindAllStringSubmatch(content, 1)
if len(kv) > 0 {
properties[kv[0][1]] = kv[0][3]
}
if io.EOF == err {
break
}
}
if nil != configErr {
fmt.Println("Failed to configure program -> ", configErr)
fmt.Scanln()
return
}
localMp3Path := properties["saveLocation"]
fmt.Println(localMp3Path + "hello worlddddddddddddddddddddddddddd")
}


the content of config.ini
saveLocation=c:\golang\workspace\helloworld\test\src\
baseUrl=http://test.com/eng/ez/morning

the expected result:
c:\golang\workspace\helloworld\test\src\hello
worlddddddddddddddddddddddddddd

but the actual output result:
hello worlddddddddddhelloworld\test\src\

what's happened to the string from regexp function...

Thanks

reader.ReadString('\n') is splitting the input on '\n', but on Windows
the line delimiter is "\r\n" so the "\r|" remains at the end of the line
returned by ReadString('\n'). You need to either switch to using ReadLine()
or check for and trim off the "\r" at the end of the line.
