如何在 notepad++ 中删除“:”前包含少于 3 个字母的所有行

我想删除用户名中其他字符前后包含少于 3 个字母的所有行，但我不需要对密码进行任何更改，这就是为什么我在“：”之前说

完整示例文件包含：

@user1example:keepline6
~!@#$%^&*(1)_+:deleteline1
..........:deleteline2
[45364\H]..;".:deleteline3
t!esting.1:keepline9
...+++#$29:deleteline4
5666D6666X67:deleteline32
namestart:keepline0
..............:deleteline8
____________:deleteline7
~!@#$%^&*()+=_-[]{}\/';.<>,:deleteline11
1start$go2deep_:keepline20
#(gold2bestar):keepline15

21Gt:deleteline89
@dF.:deleteline67

¥5G5Y.....:deleteline94

需要结果：

@user1example:keepline6
t!esting.1:keepline9
namestart:keepline0
1start$go2deep_:keepline20
#(gold2bestar):keepline15
username9example1:5password0example1

  • Ctrl+H
  • 找什么：^(?:[^a-z]*[a-z]){0,2}[^a-z:]*:.*\R|^[^:]{0,2}:.*\R|^[^:]*:.{0,2}\R
  • 用。。。来代替：EMPTY
  • Replace all

解释：

^               : begining of line
  (?:           : start non capture group
    [^a-z]*     : 0 or more any character that is not a letter
    [a-z]       : a letter
  ){0,2}        : group is repêated up to 2 times
  [^a-z:]*      : 0 or more character that is not letter or :
  :             : literally :
  .*            : 0 or more any character
  \R            : any kind of line break

 |              : OR

^               : begining of line
  [^:]{0,2}     : 0 up to 2 character that is not :
  :             : literally :
  .*            : 0 or more any character
  \R            : any kind of line break

 |              : OR

^               : begining of line
  [^:]*         : 0 or more character that is not :
  :             : literally :
  .{0,2}        : up to 2 any character
  \R            : any kind of line break
  • 请勿检查. matches newline

给定示例的结果：

@user1example:keepline6
t!esting.1:keepline9
namestart:keepline0
1start$go2deep_:keepline20
#(gold2bestar):keepline15
username9example1:5password0example1
use123:keepline100
