### iexpand()

Source: https://facelessuser.github.io/bracex

Similar to `expand()`, but returns a generator instead of a list. This is useful for handling very large numbers of expansions efficiently.

```APIDOC
## iexpand()

### Description
Returns a generator that yields expanded strings one by one. This is memory-efficient for large expansion sets. It accepts the same parameters as `expand()`.

### Parameters
#### Path Parameters
None

#### Query Parameters
None

#### Request Body
None

### Parameters
- **string** (string) - Required - The string containing brace expressions to expand.
- **keep_escapes** (bool) - Optional - If True, escape characters are preserved in the output strings. Defaults to False.
- **limit** (int) - Optional - The maximum number of expansions to generate. Set to 0 to remove the limit. Defaults to 1000.

### Request Example
```python
import bracex

for expansion in bracex.iexpand(r'item-{a,b,c}'):
    print(expansion)
# Output:
# item-a
# item-b
# item-c
```

### Response
#### Success Response (200)
- **generator** (generator) - A generator yielding expanded strings.

#### Response Example
(Output is yielded iteratively, not a single JSON response)
```

### expand()

Source: https://facelessuser.github.io/bracex

Expands a given string with brace expressions into a list of strings. It supports various expansion types like sequences, nested braces, and alphabetic ranges. Escapes can be optionally kept, and the expansion size can be limited.

```APIDOC
## expand()

### Description
Accepts a string and returns a list of expanded strings. If all expansions are empty, an empty list is returned by default. The `keep_escapes` parameter controls whether escape characters are processed or preserved. An optional `limit` parameter restricts the number of generated expansions.

### Parameters
#### Path Parameters
None

#### Query Parameters
None

#### Request Body
None

### Parameters
- **string** (string) - Required - The string containing brace expressions to expand.
- **keep_escapes** (bool) - Optional - If True, escape characters are preserved in the output strings. Defaults to False.
- **limit** (int) - Optional - The maximum number of expansions to generate. Set to 0 to remove the limit. Defaults to 1000.

### Request Example
```python
import bracex

result = bracex.expand(r'file-{1,2,3}.txt')
print(result)
# Output: ['file-1.txt', 'file-2.txt', 'file-3.txt']

result_escaped = bracex.expand(r'file\{a,b}.txt', keep_escapes=True)
print(result_escaped)
# Output: ['file\\{a,b}.txt']
```

### Response
#### Success Response (200)
- **list** (list[string]) - A list of strings, where each string is an expansion of the input.

#### Response Example
```json
["file-1.txt", "file-2.txt", "file-3.txt"]
```
```
