# glog — Simple Google-style logging wrapper for Python.

License: permissive · Maintenance: abandoned · Downloads: 104.7K/mo

## What it is and what it does

glog is a thin wrapper around Python's standard logging module that applies Google's internal logging conventions without requiring boilerplate configuration. It configures the root logger to output all messages to stderr in a consistent format: a log-level prefix, timestamp with microseconds, process ID, source filename and line number, and the message body. If your application already uses gflags, glog automatically adds a --verbosity flag; otherwise you can call log.setLevel() directly.

Beyond basic logging, glog provides check functions (check_eq, check_ge, check_lt, and others) that enforce invariants and raise FailedCheckException with detailed context when they fail, similar to C++ glog's assertion macros. This makes it useful for mixed Python/C++ codebases or when you prefer explicit runtime checks over standard Python asserts.

Use it for:

- Standardize logging format across multiple Python scripts and modules without per-module configuration
- Enforce runtime invariants using check functions (check_eq, check_ge, etc.) with automatic stack traces on failure
- Integrate logging into applications that already depend on gflags for command-line argument handling
- Port logging patterns from C++ glog to Python while maintaining similar output format and behavior

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

A simplified Google-style logging wrapper that configures Python's standard logger to output consistently formatted messages to stderr with minimal setup.

No. The package is abandoned (last release 2016-12-14, last commit 2022-11-07) with no maintenance or security updates. While it has low install friction and a permissive license, its age and lack of active development make it a poor choice for new projects. Consider actively maintained alternatives like the standard logging module or structured logging libraries instead.

## Install

pip install glog
uv add glog
poetry add glog

## Installing glog

Before you install: Low install friction with only two lightweight runtime dependencies (python-gflags and six). However, the package is abandoned—last release was 2016-12-14 and last commit 2022-11-07—so expect no maintenance or security updates.

License in practice: BSD license is permissive, allowing commercial and private use with minimal restrictions. You may use and modify the code freely as long as you retain the license notice.

Quickstart:

pip install glog

import glog as log

log.setLevel("INFO")
log.info("It works.")
log.warn("Something not ideal")
log.error("Something went wrong")

Verify before relying:

- Whether python-gflags and six remain actively maintained and compatible with modern Python versions
- Whether the abandoned status and lack of updates since 2016 pose compatibility issues with current Python releases
