Delete All Comments in a File With VS Code
What if you want to delete all comments in a file with VS Code?
VS Code has a find and replace feature that support regular expression, so we can use that feature to automatically find line starting with hash (#), Here we go:
1. Press ctrl + f
2. Click on "Use regular expression" button on "find and replace" widget
3. Type the regular expression: ^#.*$\n
4. Leave the "Replace" field empty
5. Click "Replace All" button
And all of your comment deleted, actually it is replaced by the empty character.
Notes ^#.*$\n :
• ^ = matches position just before the first character of the string
• # = character that we want to find
• . = matches a single character. Does not matter what character it is, except newline
• * = matches preceding match zero or more times
• $ = matches position just after the last character of the string
• \n = Line feed character
