NetLogo以字符列表的形式读入文件 [英] NetLogo read in file as list of characters

问题描述

我是NetLogo的新手。我有一个有一行值的文本文件：

  ABC 
 CDC 
 BBC 
  

我试图在文件的第一行读取字符列表（例如[ABC]），我一直试图使用文件读取线，但它创建一个字符串ABC，而不是。 file-opentest.txt
observer> show file-read-line
observer：ABC

解决方案

您需要将每行从一个字符串转换为一个列表。 NetLogo并没有直接做这个工作，但是写一个这样的记者是相对简单的：

  to-report string- to-list [s] 
报告ifelse-value为空？ s 
 [[]] 
 [先输入先前的字符串到列表] 
结束
  

然后：

 观察者>显示字符串到列表文件读取行
观察者：[ABC] 
  

I am new to NetLogo. I have a text file that has one row of values:

ABC
CDC
BBC

I am trying to read in the first line of that file as a list of characters (e.g. [A B C]), I have been trying to use file-read-line, but it creates a string "ABC" instead.

observer> file-open "test.txt"
observer> show file-read-line
observer: "ABC"

解决方案

You will need to convert each line from a string to a list. NetLogo has no primitive to do that directly, but it's relatively simple to write a reporter that does it:

to-report string-to-list [ s ]
  report ifelse-value empty? s
    [ [] ]
    [ fput first s string-to-list but-first s ]
end

And then:

observer> show string-to-list file-read-line
observer: ["A" "B" "C"]
