tail -f and miller

[aborruso]

Hi,
I have the below input file.

Using miller 5 I can monitor on screen file change using

tail -f input.csv | mlr --icsvlite --otsv --ifs "," cat

If I use Miller 6 I have no output on screen.

If in miller 5 I change my command in

mlr --icsvlite --opprint --ifs "," cat input.csv

I have no output.

Am I doing something wrong? Is there a more correct way to do it?
I would like to use Miller to monitor file changes, because I need to print better tail output on screen.

Thank you

@aborruso sorry for the delay!!!! Somehow I missed seeing this :(

mlr --icsvlite --opprint --ifs "," cat input.csv

This one is as designed -- PPRINT output format needs to obtain all rows to be output before printing any, since it needs to compute maximum column widths in order to do pretty-printed alignment.

The other one is a bug (and a regression ...) 😢 👀
