VimGolf - real Vim ninjas count every keystroke!

From brakets to parens

This is one of the most common problem when you wrap an array for error handling. Vim is useful when you convert foo[i][j][k] into foo(i, j, k) for many times.

Start file

int main() {
	glm::vec3 umax(
		(vx[i+1][j][k]-vx[i][j][k])/2,
		(vy[i][j+1][k]-vy[i-1][j+1][k])/2,
		(vz[i][j][k+1]-vz[i-1][j][k+1])/2
	);
	glm::vec3 umin(
		(m_vx[i][j][k]-m_vx[i-1][j][k])/2,
		(m_vy[i][j][k]-m_vy[i-1][j][k])/2,
		(m_vz[i][j][k]-m_vz[i-1][j][k])/2
	);
}

End file

int main() {
	glm::vec3 umax(
		(vx(i+1, j, k)-vx(i, j, k))/2,
		(vy(i, j+1, k)-vy(i-1, j+1, k))/2,
		(vz(i, j, k+1)-vz(i-1, j, k+1))/2
	);
	glm::vec3 umin(
		(m_vx(i, j, k)-m_vx(i-1, j, k))/2,
		(m_vy(i, j, k)-m_vy(i-1, j, k))/2,
		(m_vz(i, j, k)-m_vz(i-1, j, k))/2
	);
}
