# Ranger: CUDA-enabled range helpers for range-based for loops
2+
3+
Facilities for generating simple index ranges for C++ range-based for loops. Includes support for
4+
CUDA grid-stride ranges.
5+
6+
## Examples:
7+
8+
9+
```
10+
// generate values from 0 to N
11+
for (auto i : range(N)) {
12+
std::cout << i << std::endl;
13+
}
14+
```
15+
16+
```
17+
// generate values from `begin` to `end`
18+
for (auto i : range(begin, end)) {
19+
std::cout << i << std::endl;
20+
}
21+
```
22+
23+
```
24+
// generate values stepping by `step` from `begin` to `end`
25+
for (auto i : range(begin, end, step)) {
26+
std::cout << i << std::endl;
27+
}
28+
```
29+
30+
```
31+
// generate values from 0 to N in a kernel
32+
__global__ void size_kernel(int N, int* out)
33+
{
34+
for (auto i : grid_stride_range(N)) {
35+
out[i] = i;
36+
}
37+
}
38+
```
39+
40+
```
41+
// generate values from begin to N in a kernel
42+
__global__ void begin_end_kernel(int begin, end, int* out)
43+
{
44+
for (auto i : grid_stride_range(begin, end)) {
45+
out[i-begin] = i;
46+
}
47+
}
48+
```
49+
50+
```
51+
// generate values stepping by `step` from 0 to N in a kernel
52+
__global__ void step_kernel(int N, int step, int* out)
53+
{
54+
for (auto i : grid_stride_range(0, N, step)) {
55+
out[i / step] = i;
56+
}
57+
}
58+
```
