Phpstorm regular Match Delete comment Line (replace comment behavior blank line)

Using Phpstorm to write PHP and JavaScript code, it feels good and very comfortable to use.

Encountered a requirement, sometimes when reading the framework source code, want to filter (delete) out of the source code comment lines, if the manual row-by-line deletion shows unscientific.

Of course the strong regular match (REGEXP regular expression) was thought of, and by writing a regular expression to find out all the comment lines and replace them with empty, the requirement was fulfilled.

1. Ctrl + F, enter the regular expression:(\/\/.*$) | ( \/\*(.| \s) *?\*\/)

2. Ctrl + R, do not enter:

3. Click Replace all on the back

However, it was found that this did not fully fulfill our needs, but instead of replacing the comment line with a blank line.

So, let's write a regular expression that matches the empty line and deletes it.

1.ctrl + F, input regular expression: ^\n

2.ctrl + R, no input

3. Click Replace all on the back

However, it was found that the blank line was not completely deleted. (There are some empty lines not deleted)

So, we continue to come up with a regular match to delete.

1.ctrl + F, input regular expression: \s\n

2.ctrl + R, no input

3. Click Replace all on the back

OK, here, all the empty lines are deleted. Have a good time-:)

In fact, these three steps should be able to synthesize one step to achieve, we can think of!
