How to trim specific text
问题
我有一个文件中的一些文本。文本如下：
#cat tmp
host = "192.168.2.80"
port = 5432
user = "pnmsuser"
password = "PNMS$$$$$$"
dbname = "pnms"
我想要将文本修整为以下形式：
"192.168.2.80"
5432
"pnmsuser"
"PNMS$$$$$$"
"pnms"
我尝试了以下修整的方法：
func dbFileTrimming() {
dat, err := ioutil.ReadFile("tmp")
check(err)
for key, line := range strings.Split(strings.TrimRight(string(dat), "\n"), "\n") {
// println(key, line)
if key == 3 {
line := string([]rune(line)[11:])
fmt.Println(line)
} else if key == 4 {
line := string([]rune(line)[9:])
fmt.Println(line)
} else {
line := string([]rune(line)[7:])
fmt.Println(line)
}
}
}
是否有更简单的方法来实现这个目标？
英文:
I have some text in file.Text like below:
#cat tmp
host = "192.168.2.80"
port = 5432
user = "pnmsuser"
password = "PNMS$$$$$$"
dbname = "pnms"
Just I want text like below after trimming:
"192.168.2.80"
5432
"pnmsuser"
"PNMS$$$$$$"
"pnms"
I try to trim like below
func dbFileTrimming() {
dat, err := ioutil.ReadFile("tmp")
check(err)
for key, line := range strings.Split(strings.TrimRight(string(dat), "\n"), "\n") {
// println(key, line)
if key == 3 {
line := string([]rune(line)[11:])
fmt.Println(line)
} else if key == 4 {
line := string([]rune(line)[9:])
fmt.Println(line)
} else {
line := string([]rune(line)[7:])
fmt.Println(line)
}
}
}
Is there a simple method for this?

将 = 后面的内容截取出来：
for _, line := range strings.Split(strings.TrimRight(string(dat), "\n"), "\n") {
line = line[strings.Index(line, " = ")+3:]
fmt.Println(line)
}
英文:
Chop the line after the =:
for _, line := range strings.Split(strings.TrimRight(string(dat), "\n"), "\n") {
line = line[strings.Index(line, " = ")+3:]
fmt.Println(line)
}

这看起来像是一个INI文件，或者类似的文件，可以使用像go-ini这样的库来处理。
另外，你可以尝试使用Strings.split()函数，并将结果放入一个map中。下面是一个简单而未经测试的示例代码：
result := map[string]string{}
for _, line := range strings.Split(string(dat), "\n") {
split := strings.Split(line, "=")
key := strings.Trim(split[0], " ")
value := strings.Trim(split[1], " ")
result[key] = value
}
英文:
This looks like an INI file, or similar enough so that libraries like go-ini could work.
Alternatively, try Strings.split() and putting the result in a map. Quick and dirty / untested:
result := map[string]string
for _, line := range strings.Split(string(dat), "\n") {
split := strings.Split(line, "=")
key := strings.Trim(split[0])
value := strings.Trim(split[0])
result[key] = value
}
