Usage: pb pl [OPTIONS] [POLARS_EXPRESSION]
Execute Polars expressions and display results.
Execute Polars DataFrame operations from the command line and display the
results using Pointblank's visualization tools.
POLARS_EXPRESSION should be a valid Polars expression that returns a
DataFrame. The 'pl' module is automatically imported and available.
Examples:
# Direct expression
pb pl "pl.read_csv('data.csv')"
pb pl "pl.read_csv('data.csv').select(['name', 'age'])"
pb pl "pl.read_csv('data.csv').filter(pl.col('age') > 25)"
# Multi-line with editor (supports multiple statements)
pb pl --edit
# Multi-statement code example in editor:
# csv = pl.read_csv('data.csv')
# result = csv.select(['name', 'age']).filter(pl.col('age') > 25)
# Multi-line with a specific editor
pb pl --edit --editor nano
pb pl --edit --editor code
pb pl --edit --editor micro
# From file
pb pl --file query.py
Piping to other pb commands
pb pl "pl.read_csv('data.csv').head(20)" --pipe | pb validate --check rows-distinct
pb pl --edit --pipe | pb preview --head 10
pb pl --edit --pipe | pb scan --output-html report.html
pb pl --edit --pipe | pb missing --output-html missing_report.html
Use --output-format to change how results are displayed:

pb pl "pl.read_csv('data.csv')" --output-format missing
pb pl "pl.read_csv('data.csv')" --output-format info
Note: For multi-statement code, assign your final result to a variable like
'result', 'df', 'data', or ensure it's the last expression.
