Cvg
Examples
cvg --present colA input.csv
cvg --missing colA input.csv
cvg --regex 'colA:/\d+/' input.csv
cvg --detect-missing input.csv
cvg --lt 'colA:5' input.colA
Multiple tests:
cvg --present colA --missing colB input.csv
Multi files: (different column order OK)
cvg --present colA input1.csv input2.csv
TODO
DONE allows special "PRESENT" filter
DONE takes multiple csvs as input
DONE allows special "FALSE_OR_BLANK" filter
DONE combines tests
DONE allows single string matching
DONE allows multiple option matching
DONE allows regex matching
DONE allows > >= < <= comparisons
DONE treat as missing %w{ N/A n/a NULL null - #DIV/0 #REF! #NAME? NIL nil NA na #VALUE! #NULL! NaN #N/A #NUM! ? }
writes report (why rejected row, checks missing and extra columns across input files)
dup checks on certain cols
optionall uses minimal set of headers shared by all
