bug-trail-core 2.2.0

Local static html error logger to use while developing python code.

Bug Trail

This is a workstation logger to capture bugs encountered while you are writing code.

In other words, it is an HTML report writer for your logs, even if they aren't errors if that is your thing.

Installation

Install this with your app. It has as few dependencies as I could manage.

pip install bug-trail-core

To generate the static website install this in an isolated global virtual environment.

pipx install bug-trail

Usage

Configuration is optional via a pyproject.toml file and the logging modules ordinary configuration options. See example code-as-config

This is the schema with the default values.

[tool.bug-trail]
app_name = "bug_trail"
app_author = "bug_trail"
report_folder = "logs"
database_path = "bug_trail.db"

import bug_trail
import logging

section = bug_trail.read_config(config_path="../pyproject.toml")
handler = bug_trail.BugTrailHandler(section.database_path, minimum_level=logging.ERROR)
logging.basicConfig(handlers=[handler], level=logging.ERROR)

logger = logging.getLogger(__name__)
logger.error("This is an error message")

To generate to the log folder relative to the current working directory:

bug_trail --output logs --db error_log.db

Picologging

If you want to use picologging, install it. Everything is the same except you use the PicoBugTrailHandler.

import bug_trail
import logging

section = bug_trail.read_config(config_path="../pyproject.toml")
handler = bug_trail.PicoBugTrailHandler(
    section.database_path, minimum_level=logging.ERROR
)
logging.basicConfig(handlers=[handler], level=logging.ERROR)

logger = logging.getLogger(__name__)
logger.error("This is an error message")

Do more with your data

pipx install datasette
datasette bug_trail.db

Security

None. Do not publish your error log to the internet or to public Github. Add the log folder to your .gitignore file.

Advanced

Get ctags from here

./ctags -R -f fish_tank.tags fish_tank

Prior Art

Inspired by elmah. bug_trail is much less ambitious, as this is just a browsable, static HTML report.

If you want logger for a website, hosted in your Flak or Django website:

• Flask-ErrorsHandler
• django-elmah

These are the closest "write logs to HTML" projects I could find:

• PyLog2html
• Gist - https://gist.github.com/ColinDuquesnoy/8296508
• dblogging - Uses sqlite, but does not use standard library logging framework

If you want someone else to do it all for you

• Sentry
