`tbtrim` is a utility to trim Python traceback information. By assigning user-refined [`sys.excepthook`](https://docs.python.org/3/library/sys.html#sys.excepthook), one can easily customize the behavior after an exception is raise and uncaught, and just before the interpreter prints out the given traceback and exception to `sys.stderr`.

In a more human-readable way, `tbtrim` is to let you handle the last words of a program when it exits because of an exception.

## Installation

Simply run the following to install the current version from PyPI:

```shell
$ pip install tbtrim
```

Or install the latest version from the git repository:

```shell
git clone https://github.com/gousaiyang/tbtrim.git
cd tbtrim
pip install -e .
# and to update at any time
git pull
```

## Usage

> **set_trim_rule**(*predicate*, *target*=BaseException, *exclude*=None, *strict*=False, *exception*=None)

Set the rule for trimming traceback (will set `sys.excepthook` and `threading.excepthook` if available).

You can determine whether to start trimming traceback items based on the filename (using `predicate`), and can choose to trim traceback only for some certain exceptions (using `target` and `exclude`).

**Args:**

- **predicate** (*function*): a function which takes one `str` parameter (the filename of a traceback item) and returns `bool` (returning `True` indicates that this traceback item and the following items should be trimmed)
- **target** (*class_or_tuple*): an exception or a tuple of exceptions may be given to trim traceback only for those exceptions
- **exclude** (*class_or_tuple*): an exception or a tuple of exceptions may be given to exclude them from traceback trimming
- **strict** (*bool*): indicate whether to check an exception against `target` and `exclude` in a strict mode (setting `True` uses `is` to check, `False` uses `issubclass` to check)
- **exception** (*class_or_tuple*): this is a deprecated alias of `exclude`, retained for backward compatibility

> **clear_trim_rule**()

Clear the rule for trimming traceback (restore the excepthooks).
