eclipse search - regex finding start/end of file with carriage return
提问by Mike Henke
I would like to remove any line breaks/carriage returns at the start and end of files but eclipse doesn't seem to recognize $$or ^^for end/start of file. Anyone know how to do a regex with eclipse search?
我想删除文件时的开始和结束的任何换行符/回车但是Eclipse似乎并没有认识到$$或^^最终/文件的开始。任何人都知道如何使用 eclipse 搜索进行正则表达式？
sof ^^ Start of File
eof $$ End of File

You can use \Ato represent the start of the file, and \Zto represent the end of the file.
可以用\A来表示文件的开始，也可以用来表示文件\Z的结尾。

It seems by default, the multi-line flag mis enabled in Eclipse, causing ^and $to match start- and end-of-lines. You can disable the mflag by adding (?-m)in front of your regex.
似乎默认情况下，多行标志m在 Eclipse 中启用，导致^并$匹配行首和行尾。您可以m通过(?-m)在正则表达式前面添加来禁用该标志。
I just tested it, and it only removes line breaks at the start or end of the file:
我刚刚测试了它，它只删除文件开头或结尾的换行符：
(?-m)(^\s+|\s+$)
