Simple macro to remove blank lines

2 discussion posts
I've created this macro which appears to work fine in the macro editor

[size=10pt]using System;

public static class ClipboardFusionHelper
public static string ProcessText(string text)
string[] lines = text.Split( new string[] {"\n"} , StringSplitOptions.RemoveEmptyEntries);

text = "";

foreach (string line in lines)
text += line + "\n";
return text;

using the "Test Macro" button but it doesn't appear to do anything to the clipboard when run from tray icon. I've tried the beta release and it's the same.

I've tried adding "system.collections.generic;" and "system.text;" but that didn't change the results.

- am I still missing something I should be importing?

The problem could be that, depending on your text (and OS?), line breaks can either be "\n", "\r", "\r\n", or "\n\r". Your code only looks for "\n", so if your text also has "/r" as part of the line break, then you code leaves these in, and your output text can still appear to have line breaks.

Try this code instead:

I have a macro that I have been using that does something similar, but uses Regular Expressions:


Using RegEx, it looks for one or both "\r" and "\n" and removes them.

If you just want to clear the empty lines (and not worry about the whitespace), you can just use the last RegEx in the code above.

I haven't fully tested this, but it seems to work well for me. Let me know if you have any trouble.

Hi Splat

you're right it does appear to be the line endings that are different between the "Test Macro" option and what's on the clipboard - I did look for "\n\r" but I didn't try it the way you had the Split function, i.e. the {"\n", "\r"}.

I get SQL statements via email - they look ok in Outlook but when pasted into notepad or wherever they have extra lines in between but this looks like it cures that particular issue.

I'll take a look at the RegEx stuff - that's really useful, especially as there are so many pre-tested regex examples out there.

thanks again
