Prints function calls of the Python program

Project description

# PyTracer

Prints function calls of the Python program.

```console
$ cat example.py
def f(a):
return g(a, "20")

def g(a, b):
return b, a

f(10)

$ pytracer example.py
>example.<module>()
>example.f(10)
>example.g(10, '20') = ('20', 10)
<example.f(10) = ('20', 10)
<example.<module>() = None
```

## Installing ##

`pip install pytracer`

## Usage ##

pytracer.py [-h] [-s S] [-i I] [-f F] filename ...

positional arguments:
filename a name of the Python program

optional arguments:
-h, --help show this help message and exit
-s S max argument length to print (the default is 32)
-i I modules to ignore (comma delimited, the default is
re,glob,random,codecs,argparse)
-f F modules to focus at (comma delimited)

## Advanced Usage ##

If you want to trace a single function just add the trace() decorator. Also it is possible to ignore not interesting subcalls:

```python
import pytracer

@pytracer.no_trace()
def g():
return 42

@pytracer.trace()
def f():
return g()

f()
```

The module also can be used as a context manager:

```python
import pytracer

def f():
return 42

with pytracer.trace():
f()
```
