Removing 1000s of comments in eclipse?

Question

I installed JD-GUI to retrieve my code from a jar file. Everything works fine, except JD-GUI automatically adds annoying comments like this:

Any way I can remove them? I don't understand regex.

Answer 1

Using Eclipse:

Go to Edit > Find/Replace...
Use this regular expression in the Find box: ^/\\* [0-9 ]{3} \\*/

• ^ match start of line.
• /\\* match start of comment
• [0-9 ]{3} match exactly three digits/spaces
• \\*/ match end of comment

Make sure the Replace box is empty.
Make sure the Regular expressions checkbox is selected.
Click Replace All

Answer 2

Use CTRL+H . Within "File Search" > "Search string", check "Regular expression" and use one of the regex given by the other answers.

Then use "Replace..." to replace them all with nothing.

Answer 3

Use the utility sed to search for a regex and replace with an empty string. Here is a gist that should get you started with using it.

Since you don't understand regex, I'll help you out with it: /^\\/\\* \\d+ \\*\\//gm will find every comment block that starts at the beginning of a line and contains a line number.

Here's how it works:

• / is the start of the regex
• ^ matches the begnning of the line
• \\/\\* finds the opening /* of the comment
• (space) finds the space before the line number
• \\d+ finds any number of digits
• (space) finds the space after the line number
• \\*\\/ finds the ending */ of the comment
• /gm ends the regex and flags this as a global, multiline search
