I need to init and push some values into a array something like:

//DMD64 D Compiler 2.072.2
import std.stdio;
import std.array;

void main()
{
    bool a = true;
    bool b = false;
    bool c = false;

    bool[] boolList;
    auto boolListAppender = boolList.appender();
    boolListAppender ~= [ a, b, c];
}

Live example : http://rextester.com/TJLIXU71426

My question is about

    bool[] boolList;
    auto boolListAppender = boolList.appender();
    boolListAppender ~= [ a, b, c];


I could do the same in one line with C++:

bool boolList[] = { a, b, c };

D alternative(at least my D alternative) seem long. Is there any better way for
initialing  and pushing values at the same time.

Change the braces to brackets.

Your use of the appender method suggest to me you want to be able to append, as opposed to just initialise.

module test;

import std.stdio;
import std.array;

void main()
{
    bool[] boolList;

    bool a = true;
    bool b = false;
    bool c = false;

    boolList ~= [ a, b, c ];

    bool d = true;
    bool e = false;
    bool f = false;

    boolList ~= [ d, e, f ];

    // ...
}
