Parse a COBOL copybook string and get field positions.

from copybook import Copybook cb = Copybook('') cb.parse( struct=" 01 RECORD. 05 NAME PIC X(30). 05 AGE PIC 9(3). " ) print(cb.layout) # Example output: {'NAME': (1, 30), 'AGE': (31, 33)}

Debug

Known issues

gotchaThe parse method does not accept file paths; you must read the copybook file yourself and pass the content as a string.

fix

Use open('copybook.cbl').read() to get the content, then pass it to parse.

affects: all

gotchaCopybook layout indices are 1-based, not 0-based.

fix

When using layout offsets, remember that the first byte is 1. Adjust if your downstream expects 0-based.
