### Use wazuhregex Python API classes

Source: https://github.com/zbalkan/wazuhregex/blob/main/README.md

Import the primary classes directly from the package. The example shows WazuhRegex, RegexComparer, and Engine usage. The 100 ms and 20-line limits belong to the CLI; direct Python methods remain ordinary library calls.

```python
from wazuhregex import Engine, RegexComparer, WazuhRegex

tool = WazuhRegex(r"(\d+)")

is_match, spans = tool.os_regex("30 Agustos 2020")
if is_match:
    print(spans)  # [(0, 2), (11, 15)]
    print(tool.get_substrings())  # ["30", "2020"]

is_match, spans = tool.os_match("Error: disk full")
is_match, spans = tool.pcre2_regex("30 Agustos 2020")

comparer = RegexComparer()
parsed = comparer.parse(r"\d+", Engine.PCRE2)
```

Source: https://github.com/zbalkan/wazuhregex/blob/main/README.md

Use either the console command or the module entry point to run the CLI. The CLI accepts at most 20 physical input lines per invocation, each evaluated in an isolated worker with a 100 ms wall-clock limit.

```bash
wazuhregex '<PATTERN>'
python -m wazuhregex '<PATTERN>'
```
