nl_max

The maximum number of consecutive newlines (3 = 2 blank lines).

Note:

• this option conflicts with nl_before_block_comment
• this option conflicts(overrides) other options like nl_max_blank_in_func

Examples

Removing empty lines

If config is nl_max = 1 all the empty lines get removed:

#include <iostream>


int gg = 10;

int main()
{

    int a = 20;
    int b = 10;
    int c = b;



    if (a<100) {
        c = a;
    }

    std::cout << "Finally c is " << c << '\n';
}

transformed to

#include <iostream>
int gg = 10;
int main()
{
    int a = 20;
    int b = 10;
    int c = b;
    if (a<100) {
        c = a;
    }
    std::cout << "Finally c is " << c << '\n';
}

With other options

nl_max overrides some other options, listed in "Blank line options" section of documentation. For example, following config

# Uncrustify-0.69.0_f
nl_max            = 0
nl_max_blank_in_func = 1

removes empty lines inside main function, but leaves others.

Like

#include <iostream>


int gg = 10;

int main()
{

    int a = 20;
    int b = 10;
    int c = b;



    if (a<100) {
        c = a;
    }

    std::cout << "Finally c is " << c << '\n';
}

transformed to

#include <iostream>


int gg = 10;

int main()
{
    int a = 20;
    int b = 10;
    int c = b;
    if (a<100) {
        c = a;
    }
    std::cout << "Finally c is " << c << '\n';
}
