The correct column width is calculated from the first n rows not the full file. A stream does not work for tv because a stream does not know how many rows are

The correct column width is calculated from the first n rows not the full file.
A stream does not work for tv because a stream does not know how many rows are in the file a priori. Displaying the dimensions of the file is a priority for `tv`. I am very happy with that trade-off. I would rather know the dimensions of a file than have a file stream of unknown dimensions.
- adamdusty 5y agoIf you did it the way he's talking about you would stream through the file to find how many rows and write the file as a temp file that you could re-parse for the actual data. I'm not saying you should or shouldn't, but your use case doesn't bar you from using streams.
- flusteredBias 5y agoI see. Thanks for the clarification.
