Catcher - Beautiful tracebacks

python-catcher module generates highly informative crash reports (including source code and locals) in two possible forms:

• generates a text file report, which you can save it where it is needed to;
• generates HTML-page-like report, submits it to the web and generates a permalink.

Quick use for HTML-page-like report::

import catcher

try:
    launch_important_stuff()
except Exception as e:
    report = catcher.collect(e)
    html = catcher.formatters.HTMLFormatter().format(report, maxdepth=4)
    url = catcher.uploaders.AjentiOrgUploader().upload(html)

    print('Application has crashed. Please submit this link along with the bug report:')
    print(url)

Quick use for text file report::

import catcher

try:
    print('you cannot' / 'divide this')
except Exception as e:
    report = catcher.collect(e)
    text = catcher.formatters.TextFormatter().format(report)
    with open(f'crash_{report.timestamp}.txt', 'w') as f: f.write(text)

Example text file report::
