IgnoreFieldsCSV

[tomstock1337]

I was comparing two CSV files and attempting to ignore the first column, and the last column (column 41). Column 41 only existed on CSV A and not CSV B; and the plugin was not working at all, not even first column was ignored.

Column 41 was defunct and no longer needed, so I wanted to ignore it from the old file. I had to add a dummy column to the CSV file in order for the plugin to work.

Two possible solutions:

1. State in the plugin information that the two files need to have the same column count
2. Allow for column numbers greater than the column count of the CSV file, and just ignore those column ignores.

The IgnoreFieldsComma prediffer plugin accepts arguments like IgnoreFieldsComma 41-, but unfortunately, both files must have the same number of columns.

If you don't mind ignoring the differences after column 41, he can extract and compare only columns 1 to 40 using the QueryCSV unpacker plugin as shown below. (The first time you use QueryCSV, a download of the q command occurs)

QueryCSV "SELECT C1,C2,C3,C4,C5,C6,C7,C8,C9,C10,C11,C12,C13,C14,C15,C16,C17,C18,C19,C20,C21,C22,C23,C24,C25,C26,C27,C28,C29,C30,C31,C32,C33,C34,C35,C36,C37,C38,C39,C40 FROM - "

That works as well. If the documentation were just updated to say that the columns of both files need to be the same; it might save others quite a bit of time; a it took me awhile of testing to figure out what was happening.
