is there a way/tool to automatically remove blank lines on kdevelop Version 4.3.1?
For instance

Code: Select all

    tmpTime.tm_year = RTC_Time->bYear1 * 100 + RTC_Time->bYear - 1900;

    tmpTime.tm_mon = RTC_Time->bMonth - 1;

    tmpTime.tm_mday = RTC_Time->bDay;

should be replaced by

Code: Select all

    tmpTime.tm_year = RTC_Time->bYear1 * 100 + RTC_Time->bYear - 1900;
    tmpTime.tm_mon = RTC_Time->bMonth - 1;
    tmpTime.tm_mday = RTC_Time->bDay;

Inside your document, press Ctrl+R (for Search/Replace)

Then enter "\n\n" (without quotes) in the Find input element.
Enter "" (without quotes) in the Replace input element.
Select "Regular Expression" mode.

Press Replace All.

thanks krf but that's a kind of workaround. Are there no visual solution like a checkbox for removing the blank lines? Thanks

Nope, there's no visual indicator for that kind of action.

You can file a bug/wish against Kate (KDevelop is using Kate as editor component) on bugs.kde.org for this kind of issue. I think it would be a good idea to have a separate action such as "Remove blank lines" hidden somewhere in the top menu. Other editors have that, too (e.g. Notepad++).

Well, you can just write a Kate script to do this. Then you'll have a menu action, too.

Cheers,

@sdemattia: Wouldn't that be a nice opportunity to contribute something to Kate?

@krf, yes that's sound nice. I hope I will have time and do it within the next 2 weeks
