formatter doesn't remove empty lines [message #933741]

Hi!

If I use setLineWrap(1) and there are already n lines present, they are not reduced to 1, but there will be n+1.

Consequently, when I press Ctrl-F several times in a row, then an empty line is added every time.

The same thing happens if I use setSpace("\n"): new lines just get added.

Is this how it's meant to be, or am I using it wrong?

best regards,
Vlad

Hello Vlad,

I recommend to use the setLineWrap version with 3 parameters:

public LinewrapLocator setLinewrap(int minWraps, int defaultWraps, int maxWraps)

Here you can set the minimal allowed count of lines, default count of lines and maximal allowed count of lines.
If the maximal allowed count of line overtaken, the formatter will remove some empty lines to reduce the count of it to the maximum value.

Regards,
Boris

Hi Boris,

Of course I tried that too, and anyway, setLinewrap() just calls setLineWrap(1) which just calls setLineWrap(1,1,1).

After some digging, it looks like the problem appeared because of a terminal that was a little weird (could end with non-ignored whitespace). Removing that fixed it.

regards,
Vlad
