# Description
I have (hopefully) simplified the `log.nu` internal structure and added
customizable log format for all `log` commands
# User-Facing Changes
- [x] Replaced constants with env records for:
- ansi (newly added)
- log level
- prefix
- short prefix
- [x] Added `format` argument to all log commands
- [x] Assertions for (not) equality (equal, not equal, greater,
lesser...) now put left and right values inside `'` quotes, so the
assertions for strings are more meaningful
- [x] Documented the %-formatting of log messages
# Tests + Formatting
<!--
Don't forget to add tests that cover your changes.
Make sure you've run and fixed any issues with these commands:
- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A
clippy::needless_collect -A clippy::result_large_err` to check that
you're using the standard code style
- `cargo test --workspace` to check that all tests pass
- `cargo run -- crates/nu-std/tests/run.nu` to run the tests for the
standard library
> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr
> ```
-->
# After Submitting
<!-- If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.
