rvid.log 0.0.2

Single-file, zero-dependency, highly compatible logger

rvid.log - a nice single-file logger

Single-file, zero-dependency, highly compatible logger with useful defaults and convenient features.

My only real objections against the basic logging functionality in Python stdlib are that its default formatter doesn't have the basic information I always want and that it is too fiddly to adjust log levels.

You can just copy the single file into any project and name it anything.

Example

$ cat > test.py <<EOF
from rvid.log import getLogger
log = getLogger(name=None)
log.info("This is informational")
log.debug("This is mostly noise")
EOF

$ python test.py
[2026-03-07 23:30:39] INFO [test.py] This is informational

$ LOGGING_LEVEL=DEBUG python test.py
[2026-03-07 23:31:46] INFO [test.py] This is informational
[2026-03-07 23:31:46] DEBUG [test.py] This is mostly noise

$ LOGGING_PATH=test.log python test.py

$ cat test.log
[2026-03-07 23:31:59] INFO [test.py] This is informational

Other features

• Extra levels TRACE (below DEBUG) and IMPORTANT (between WARNING and ERROR).
• You can set log-level by logger-name, simply add more text after LOGGING_LEVEL like this: LOGGING_LEVEL_MYPACKAGE_SUBPACKAGE=DEBUG. and now loggers with name "mypackage.subpackage" will have DEBUG level but all others are left on default. You can have as many of these variables as you want in your environment.
• Allows output to multiple sinks from single logger
• Single central flip to switch, if you wish to route all log statements through stdlib logging instead.
