Phpstorm regular match deletes empty lines, comment lines (replace empty lines with empty lines), and phpstorm empty lines

Phpstorm is used to compile php and javascript code. It feels good and comfortable to use.

Sometimes, when reading the source code of the framework, you may want to filter (delete) Comment lines in the source code. It is not scientific to manually delete lines by line.

Of course, we thought of a powerful regExp regular expression. by writing a regular expression, we can find all the comment rows and replace them with null to meet our needs.

1. Press ctrl + F and enter the regular expression:(//.*$)|(/*(.|s)*?*/)

2. ctrl + R, without entering:

3. Click Replace all.

However, we found that this did not fully implement our needs, but simply replaced the comment line with a blank line.

Therefore, let's write another regular expression to match and delete empty rows.

1. Press ctrl + F and enter the regular expression:^n

2. ctrl + R, do not enter

3. Click Replace all.

However, it was found that empty rows were not all deleted. (Some blank lines are not deleted)

Therefore, we will continue to delete a regular expression matching.

1. Press ctrl + F and enter the regular expression:sn

2. ctrl + R, do not enter

3. Click Replace all.

Okay. Here, all empty rows are deleted. Have fun -:)
