Description avp 2008-02-14 09:49:26 UTC
when GCC parse a file and don't see empty last line he show warning. I propose add to Code style option-Blank lines add
option "add empty last line if she don't exist"

Bug 186355 suggests that NB should just add missing new line on saving file, without the need to call formatting.

Note that GCC does *not* want an empty line at the end of the file: it just wants to see a newline character. i.e. it wants to see:

void somefunc(void)\n


void somefunc(void)\n

What NB currently produces is:

void somefunc(void)\n

Ideally NetBeans would have would an "Ensure newline at end of file" option for each language, under Tools > Options > Editor > On Save.

There is already a plugin called "EOF Line Feed" for this, which can be enabled through Tools > Plugins > Available Plugins (works in NetBeans 8.1,
