Command Line

GEODE currently provides one command-line operation: look up a BUFR Table B descriptor by its six-digit FXY value.

Install

Install GEODE from the repository root to register the geode command:

python -m pip install -e .

Look Up a BUFR Descriptor

Use geode info bufr followed by the FXY descriptor:

geode info bufr 001003

The command prints the complete WMO BUFR/CREX Table B entry as a Python dictionary. The output includes the descriptor name, units, scale, reference value, data width, class, notes, and status.

{'ClassNo': '01',
 'ClassName_en': 'Identification',
 'FXY': '001003',
 'ElementName_en': 'WMO Region number/geographical area',
 'BUFR_Unit': 'Code table',
 ...}

The FXY value must contain exactly six digits. An unknown or malformed value causes the command to exit with an error message.

Look Up a Code Figure

For descriptors that use a WMO CodeFlag table, provide the code figure as a second positional argument:

geode info bufr 001003 1

The command first prints the complete Table B descriptor dictionary, then the matching CodeFlag dictionary. The CodeFlag result includes the FXY descriptor, code figure, entry name, notes, and status.

{'ClassNo': '01',
 'FXY': '001003',
 'ElementName_en': 'WMO Region number/geographical area',
 ...}
{'FXY': '001003',
 'CodeFigure': '1',
 'EntryName_en': 'Region I',
 ...}

The code figure must exactly match a CodeFigure value in the CodeFlag table. An unknown FXY and code-figure combination causes the command to exit with an error message.
