我已经从模板创建了一个用于字符串格式化的go项目(它允许在c#或Python风格中格式化字符串),通过性能测试,它比fmt更先进。Sprintf,你可以在这里找到它https://github.com/Wissance/stringFormatter
它的工作方式如下:
func TestStrFormat(t *testing.T) {
strFormatResult, err := Format("Hello i am {0}, my age is {1} and i am waiting for {2}, because i am {0}!",
"Michael Ushakov (Evillord666)", "34", "\"Great Success\"")
assert.Nil(t, err)
assert.Equal(t, "Hello i am Michael Ushakov (Evillord666), my age is 34 and i am waiting for \"Great Success\", because i am Michael Ushakov (Evillord666)!", strFormatResult)
strFormatResult, err = Format("We are wondering if these values would be replaced : {5}, {4}, {0}", "one", "two", "three")
assert.Nil(t, err)
assert.Equal(t, "We are wondering if these values would be replaced : {5}, {4}, one", strFormatResult)
strFormatResult, err = Format("No args ... : {0}, {1}, {2}")
assert.Nil(t, err)
assert.Equal(t, "No args ... : {0}, {1}, {2}", strFormatResult)
}
func TestStrFormatComplex(t *testing.T) {
strFormatResult, err := FormatComplex("Hello {user} what are you doing here {app} ?", map[string]string{"user":"vpupkin", "app":"mn_console"})
assert.Nil(t, err)
assert.Equal(t, "Hello vpupkin what are you doing here mn_console ?", strFormatResult)
}
