问题描述
我在 RStudio 中工作，我想在 .R 脚本的每个选定的非空行的末尾放置一个特定的字符串.
I am working in RStudio and I would like to place a certain string at the end of every selected non-empty line of a .R script.
我尝试使用查找和替换正则表达式，但我只能选择一行的最后一个字符(使用 .$)，这没有帮助，因为我不想替换这个字符.我尝试了 \n\r 等的组合，但这些没有返回结果.
I tried to use find and replace with regex but I am only able to select the last character of a line (using .$) which is not helpful as I do not want to replace this character. I have tried combinations of \n\r etc but these return no results.
我正在寻找一种方法将 .$ 选择的字符携带"到我的替换"字符串中(我认为这是不可能的)或选择新行并表达/在我的替换字符串中定义一个新行.
I am seeking a method either to "carry" the character selected by .$ into my "replace" string (I don't think this is possible) or to select the new line and express/define a new line in my replace string.
我既不是 rstudio 高级用户，也不是正则表达式向导，因此非常感谢任何帮助或线索.
I am neither an rstudio power-user nor a regex wizard so any help or clues are greatly appreciated.
推荐答案
尝试以下替换全部:
查找:
(.)$
替换:
\1your_string
数量 (.) 表示捕获给定行的最后一个字符，然后在替换中作为 \1 可用>.请注意，空行不会匹配，因为它们上面没有字符.
The quantity (.) means to capture the last character on a given line, which is then made available in the replacement as \1. Note that empty lines would not match, since they have no characters on them.
