Question

我有点击装饰器的功能。该函数的全部目的是为tq_oex_interchange类正在完成的工作添加一个CLI选项。

using System;
using System.Collections.Generic;

public class Item
{
    public static List<Item> Database;

    static Item()
    {
        Database = new List<Item>();
    }

    public Item(string name, int start, int end, params string[] orders)
    {
        Name = name;
        Start = start;
        End = end;
        Orders = new List<string>();
        foreach (string s in orders)
            Orders.Add(s);
        //putting newly created Item to database
        Database.Add(this);
    }

    //overload for creating tmp Items in GroupThem(), could be done using optinional parameter
    public Item(bool AddToDatabase, string name, int start, int end, params string[] orders)
    {
        Name = name;
        Start = start;
        End = end;
        Orders = new List<string>();
        foreach (string s in orders)
            Orders.Add(s);
        if (AddToDatabase) Database.Add(this);
    }

    public string Name { get; set; }
    public int Start { get; set; }
    public int End { get; set; }
    public List<string> Orders { get; set; }

    public List<Item> GroupedItems()
    {
        List<Item> groupedItems = new List<Item>();
        Item previous = Database[0];
        Stack<Item> sameItems = new Stack<Item>();

        foreach (Item item in Database)
        {
            if (previous.Name == item.Name)
            {
                sameItems.Push(item);
            }
            else
            {
                groupedItems.Add(GroupThem(sameItems));
                previous = item;
                sameItems.Push(item);
            }
        }
        groupedItems.Add(GroupThem(sameItems));
        return groupedItems;
    }

    private Item GroupThem(Stack<Item> sameItems)
    {
        string newName = "";
        int newEnd = 0;
        int newStart = int.MaxValue;
        List<string> newOrders = new List<string>();
        Item tmp = null;
        while (sameItems.Count > 0)
        {
            tmp = sameItems.Pop();
            if (tmp.Start < newStart)
                newStart = tmp.Start;
            if (tmp.End > newEnd)
                newEnd = tmp.End;
            foreach (string s in tmp.Orders)
                if (!newOrders.Contains(s))
                    newOrders.Add(s);
            newName = tmp.Name;
        }
        return new Item(false, newName, newStart, newEnd, newOrders.ToArray());
    }

    public override string ToString()
    {
        string tmp = "";
        foreach (string s in Orders)
            tmp += " " + s;
        return "Name = " + Name + ", Start = " + Start + ", End = " + End +", Orders  = "+ tmp;
    }
}

class Program
{
    static void Main(string[] args)
    {

        Item item1 = new Item("A", 1, 2, "C", "D");
        Item item2 = new Item("A", 2, 3, "C", "E");
        Item item3 = new Item("B", 4, 5, "F");
        Item item4 = new Item("A", 6, 7);
        Item item5 = new Item("A", 7, 8, "D");
        Item item6 = new Item("A", 9, 10, "E");

        foreach (Item item in item1.GroupedItems())
        {
            Console.WriteLine(item);
        }
    }
}

但是，当我使用命令

执行我的脚本时

@click.command()
@click.option('-input_file', help='The input file to process')
@click.option('-output_file', help='The output file to create')
@click.option('-part_num_col', help='The column containing the part numbers')
@click.option('-summate_cols', help='The columns to summate')
def run(input_file, output_file, part_num_col, summate_cols):
    from re import split
    summate_cols = [int(i) for i in split(',', summate_cols)]
    part_num_col = int(part_num_col)
    teek = tq_oex_interchange()
    click.echo("Working...")
    teek.scan_file(input_file, output_file, part_num_col, summate_cols)

没有任何事情发生，甚至没有执行点击回声。

此外，

python tq_oex.py -input_file C:\Users\barnej78\Desktop\test_0.csv -output_file C:\Users\barnej78\Desktop\cmd.csv -part_num_col 3 -summate_cols 5,6

也没有做任何事情。

任何这些命令都没有错误或异常输出。

我做错了什么？

您是否能够从此处成功运行示例代码？

http://click.pocoo.org/5/

我从那开始并确保它有效。然后使用Click test docs：

为它编写测试

http://click.pocoo.org/5/testing/

这样当你开始调整它时，你可以运行测试来看看有什么破坏......

使用Click应用程序，我经常从一个参数开始简单，然后添加另一个以确保它仍然有效：

@click.command()
@click.argument('input_file')
def run_files(input_file):
    click.echo(input_file)

然后为此添加一个选项：

@click.command()
@click.argument('input_file')
@click.option('--output_file', help='The output file to create')
def run_files(input_file, output_file):
    click.echo(input_file, output_file)

我也喜欢设置默认值，以便进行调试：

def run_files(input_file='/path/to/input_file',
              output_file='/path/to/output_file'):
    click.echo(input_file, output_file)

Python：为什么我的Click CLI没有执行所需的功能？
