Question

我正试图从这样的方式导出常量：

package log

const (
    FATAL = iota // fatal errors
    ERROR = iota // errors might happend
    DEBUG = iota // debug mode
) // const for logging levels

但是我得到了golint错误：

exported const FATAL should have comment  (or a comment on this block) or be unexported (golint)

这是正确的，我在获取log.FATAL等访问权限时遇到错误。

Answer 1

文档的评论总是紧接在他们记录的内容之前。

$gpx = simplexml_load_file($folder.$file);
$trasa ="'LINESTRING(";
foreach ($gpx->trk->trkseg->trkpt as $trkpt) {
    $lat = (string) $trkpt['lat'];
    $lon = (string) $trkpt['lon'];
    $trasa .= $lon;
    $trasa .=" ";
    $trasa .= $lat;
    $trasa .=",";
}
$trasa =rtrim($trasa,",");
$trasa .=")',0";
unset($gpx);
$ins = @mysql_query("INSERT INTO punktytras(nick,punkty) VALUES('$nick', LineFromText($trasa))");

您还可以为一组常量提供注释：

// Comment
const (
    FATAL = iota
    ERROR
    DEBUG
)

导出的const应该有一个注释
