這裏的總菜鳥。

我工作的定製由Brett特普斯特拉做一個腳本 - http://brettterpstra.com/2013/11/01/save-pocket-favorites-to-nvalt-with-ifttt-and-hazel/

煤礦是不同的用途：我想用一個特定的標籤保存我的通知板的書籤到一個文件中的Dropbox在降價。

我給它一個文本文件如：

Title: Yesterday is over. 
URL: http://www.jonacuff.com/blog/want-to-change-the-world-get-doing/ 
Tags: 2md, 2wcx, 2pdf 
Date: June 20, 2013 at 06:20PM 
Image: notused 
Excerpt: You can't start the next chapter of your life if you keep re-reading the last one. 

，並將其輸出的降價文件。

除了'摘錄'（見上文）不止一行時，一切都很好。有時候是幾段。當發生這種情況時，它停止工作。當我從命令行輸入時，它仍然在等待更多輸入。

下面是它不工作的一個文件的一個例子：

Excerpt: Contrast two men from the 19th century: Max Jukes and Jonathan Edwards. 

Max Jukes lived in New York. He did not believe in Christ or in raising his children in the way of the Lord. He refused to take his children to church, even when they asked to go. Of his 1,026 descendants: 
•300 were sent to prison for an average term of 13 years 
•190 were prostitutes 
•680 were admitted alcoholics 
His family, thus far, has cost the state in excess of $420,000 and has made no contribution to society. 

Jonathan Edwards also lived in New York, at the same time as Jukes. He was known to have studied 13 hours a day and, in spite of his busy schedule of writing, teaching, and pastoring, he made it a habit to come home and spend an hour each day with his children. He also saw to it that his children were in church every Sunday. Of his 929 descendants: 
•430 were ministers 
•86 became university professors 
•13 became university presidents 
•75 authored good books 
•7 were elected to the United States Congress 
•1 was Vice President of the United States 
Edwards’ family never cost the state one cent. 

We tend to think that our decisions only affect ourselves, but they have ramifications for generations to come. 

這裏是什麼樣子後，我運行命令的截圖：https://www.dropbox.com/s/i9zg483k7nkdp6f/Screenshot%202013-11-22%2016.39.17.png 我希望這件事情很容易。有任何想法嗎？

Answer 1

這個怎麼樣？相應地修改input.each_line面積：

headers = {} 
key = nil 
input.each_line do |line| 
    match = /^(?<key>\w+)\s*:\s*(?<value>.*)/.match(line) 
    value = line 
    if match 
    key = match[:key].strip 
    headers[key] = match[:value].strip 
    else 
    headers[key] += line 
    end 
end 

首先，拆分對剛剛「：」是危險的，因爲這可以在內容。相反，（從代碼簡化）/^\w+:.*/的正則表達式將匹配「Word：Content」。由於「摘錄：」後面的行不加前綴，因此您需要掛在上次看到的關鍵字上，並且只要沒有該行的關鍵字即可附加。您可能需要在那裏添加一個換行符，具體取決於您使用該頭信息所做的操作，但似乎可行。
