我试图在我的第一个Click CLI应用程序上进行一种递归调用.要点是让子命令与第一个相关联,因此,我试图将它们全部分离到不同的文件/模块中以提高它的可维护性.

我有现在directory:

root
|-commands
|-project
|---__init__
|---command1
|---command2
|-database
|---__init__
|---command1
|---command2

这是我的主要文件:

import click
from commands.project import project
from commands.database import database


@click.group(help="Main command")
def main():
    pass


main.add_command(project)
main.add_command(database)

我的项目__init__档案:

from commands.project.command1 import *
from commands.project.command2 import *
import click


@click.group(help="Projects")
def project():
    pass


project.add_command(command1)
project.add_command(command2)

我的commands.project.command1档案:

import click


@click.command()
def command1():
    """
    Execute all the steps required to update the project.
    """
    pass

这里的要点是,每次我想添加一个新的子命令时,我需要:

1. .py在相应的子命令/子模块文件夹中添加包含所有代码的文件(显然!)

2. import在它的__init__文件上添加它的声明

3. 将此新命令与其父项(项目/数据库,在本例中)相关联 …

我想得到下一个日期从一个给定的字符串运行cron,如Cron Format with secondsparameter(不完全等于cron格式).

我的代码:

$cron_format = explode(" ", "00 00 00 01 * *"); // <second> <minute> <hour> <day> <month> <week_day>
$date_diff   = explode(" ", "s i H d m w");     // php Date @link http://php.net/manual/en/function.date.php
$format = [];

foreach( $date_diff as $key=>$value) {
    $format[$value] = $cron_format[$key] !== "*" ? date($value, strtotime($cron_format[$key])) : date($value);
}

$spf = sprintf(
"%s-%s-%s %s:%s:%s", 
date("Y"), $format["m"], $format["d"], $format["H"], $format["i"], $format["s"]
);

$date = DateTime::createFromFormat("Y-m-d H:i:s", $spf);

// …

我有这个数组：

0 => array:3 [
    "product_id" => "1138"
    "product_image" => "/resources/medias/shop/products/shop-6500720--1.png"
    "product_sku" => "6500722"
  ]
1 => array:3 [
    "product_id" => "1144"
    "product_image" => "/resources/medias/shop/products/shop-6501041--1.png"
    "product_sku" => "6501046"
  ]
2 => array:3 [
    "product_id" => "113"
    "product_image" => "/resources/medias/shop/products/shop-6294909--1.png"
    "product_sku" => "6294915"
]

我正在寻找的是一种获取仅包含必需列的多数组的方法（array_column不是一个选项，因为它只给我 1 列）。

我做了什么

function colsFromArray($array, $keys)
{
    return array_map(function ($el) use ($keys) {
        return array_map(function ($c) use ($el) {
            return $el[$c];
        }, $keys);
    }, $array);
}

$array = array(
    [
        "product_id"    => "1138",
        "product_image" …

它看起来很简单(也许是,只是被卡住) - >只是为了好玩,现在没有实际需要.

我懂了:

<div class="master">
    <div class="left">
        <p>LEFT</p>
    </div>
    <div class="right">
        <p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat.

我在为生产环境捆绑 webpack 时遇到一个奇怪的问题。

Unexpected token: punc (.)

这仅在 React 组件导入时发生axios

import React from "react";
import axios from "axios"; // <---------------

class SimpleComponent extends React.Component {
  render() {

    return (
      <section className="bg-white py-16">
        Simple
      </section>
    )
  }
}

export default SimpleComponent

这会导致以下错误：

$ npm run build
