Uncrustify split function call parameters

Question

I want to format the code like this:

• a) line width maximum 120

• b)- function call parameters one per line with indent if the length of the function is called is > 120 else function call in one line

• c)- it the function call is inside a if, for, while, etc... the parameters should be formatted as written at b)

I have the code (it is just a fictive):

void a_function()
{
    if(verify_if_the_conditions_are_meet(first_parameter, second_parameter, third_parameter, fourth_parameter, fifth_parameter, sixth_parameter ))
    {
        call_a_function_with_many_parameters(first_parameter, second_parameter, third_parameter, fourth_parameter, fifth_parameter, sixth_parameter);       
    }

    save(first_parameter, second_parameter, third_parameter, fourth_parameter, fifth_parameter, sixth_parameter);
}

And now, I want to have the result:

void a_function()
{
    if(verify_if_the_conditions_are_meet(
        first_parameter, 
        second_parameter, 
        third_parameter, 
        fourth_parameter, 
        fifth_parameter, 
        sixth_parameter ))
    {
        call_a_function_with_many_parameters(
            first_parameter, 
            second_parameter, 
            third_parameter, 
            fourth_parameter, 
            fifth_parameter, 
            sixth_parameter);
    }

    save(first_parameter, second_parameter, third_parameter, fourth_parameter, fifth_parameter, sixth_parameter);
}

I've used the following options in Uncrustify 0.63:

code_width = 120

ls_func_split_full = true

ls_code_width = false

nl_func_leave_one_liners = true

indent_func_call_param = true

nl_func_def_start = add

nl_func_def_start_single = remove

align_oc_msg_colon_first = false

With this settings I get just like this:

void a_function()
{
    if(verify_if_the_conditions_are_meet(first_parameter, second_parameter, third_parameter, fourth_parameter, 
        fifth_parameter, sixth_parameter ))
    {
        call_a_function_with_many_parameters(
            first_parameter, 
            second_parameter, 
            third_parameter, 
            fourth_parameter, 
            fifth_parameter, 
            sixth_parameter);
    }

    save(first_parameter, second_parameter, third_parameter, fourth_parameter, fifth_parameter, sixth_parameter);
}

Have anyone a situation where the function call is inside a if/for/while and needs to have the parameters split like this?

Answer 1

Use these settings:

nl_func_call_start_multi_line   = true
nl_func_call_args_multi_line    = true
code_width                      = 120

• code_width: Try to limit code width to N columns
• nl_func_call_start_multi_line: Whether to add newline after ( in a function call if ( and ) are in different lines.
• nl_func_call_args_multi_line: Whether to add newline after each , in a function call if ( and ) are in different lines.

Optionally with:

nl_func_call_end_multi_line     = true

• nl_func_call_end_multi_line: Whether to add newline before ) in a function call if ( and ) are in different lines.
