A utility that cures the horrible traceback displays in Python, making them more readable.
Project description
TBVaccine is a utility that pretty-prints Python tracebacks. It automatically highlights lines you care about and deemphasizes lines you don’t, and colorizes the various elements in a traceback to make it easier to parse, like so:
Installation
To install, use pip:
pip install tbvaccine
You are done!
Usage as a command-line utility
TBVaccine can be used from the command line. Just pipe STDERR into it from the program you want to watch:
./myscript.py 2>&1 | tbvaccine
And all the tracebacks will now be pretty!
Usage as a Python library
There are various ways to use TBVaccine as a Python library.
Initialize it like so:
from tbvaccine import TBVaccine
tbv = TBVaccine(
code_dir="/my/code/dir",
isolate=True
)
code_dir marks the directory we code about. Files under that directory that appear in the traceback will be highlighted. If not passed, the current directory, as returned by os.getcwd() will be used.
If isolate is False, all lines are colorized, and code_dir is ignored.
To use it in an except block:
from tbvaccine import TBVaccine
try:
some_stuff()
except:
print(TBVaccine().format_exc())
I’ll tell you about the other ways later.
