# Wurlitzer
|
|
|
|
Capture C-level stdout/stderr pipes in Python via `os.dup2`.
|
|
|
|
For more details on why this is needed, please read [this blog post](https://eli.thegreenplace.net/2015/redirecting-all-kinds-of-stdout-in-python/).
|
|
|
|
## Install
|
|
|
|
pip install wurlitzer
|
|
|
|
## Usage
|
|
|
|
Capture stdout/stderr in pipes:
|
|
|
|
```python
|
|
from wurlitzer import pipes
|
|
|
|
with pipes() as (out, err):
|
|
call_some_c_function()
|
|
|
|
stdout = out.read()
|
|
```
|
|
|
|
Capture stdout/stderr in StringIO:
|
|
|
|
```python
|
|
from io import StringIO
|
|
from wurlitzer import pipes, STDOUT
|
|
|
|
out = StringIO()
|
|
with pipes(stdout=out, stderr=STDOUT):
|
|
call_some_c_function()
|
|
|
|
stdout = out.getvalue()
|
|
```
|
|
|
|
Forward C-level stdout/stderr to Python sys.stdout/stderr,
|
|
which may already be forwarded somewhere by the environment, e.g. IPython:
|
|
|
|
```python
|
|
from wurlitzer import sys_pipes
|
|
|
|
with sys_pipes():
|
|
call_some_c_function()
|
|
```
|
|
|
|
Or even simpler, enable it as an IPython extension:
|
|
|
|
```
|
|
%load_ext wurlitzer
|
|
```
|
|
|
|
To forward all C-level output to IPython during execution.

This package is based on stuff we learned with @takluyver and @karies while working on capturing output from the [Cling Kernel](https://github.com/root-mirror/cling/tree/master/tools/Jupyter/kernel) for Jupyter.

## Wurlitzer?!
|
|
|
|
[Wurlitzer](https://en.wikipedia.org/wiki/Wurlitzer) makes pipe organs. Get it? Pipes? Naming is hard.
