getline

The function also needs to know the text on the current line , which can be retrieved using getline (), and is stored in curr_line .

该函数还需要知道当前行上的文本，可以使用getline（）来获取存储在currline中的当前行。

It grabs the specified range of lines from the buffer with a getline () and iterates through each .

它通过getline（）从缓冲区获取代码的指定范围，并对各项进行迭代。

The function then grabs every line in the current file ( getline ( 1 , ' $ ' )) and calls the built-in writefile () function to write them to disk .

函数随后获取当前文件（getline（1，'$'））中的每一行并调用内置的writefile（）函数来将它们写入到磁盘中。

The changes begin in the third code block , which uses the two-argument form of the built-in getline () function to return a list of all the lines in the range to be realigned .

从第三个代码块开始发生变化，它使用内置的getline（）函数的双参数形式来返回需要重新对齐的行的列表。
