nrw (pronounced narrow) is a simple utility that allows interactive selection of zero or more lines from STDIN.

It furthermore supports masking the input to present a clearer overview of the input lines while still returning the full, unmasked input lines following selection.

Requires git and stack.

$ git clone https://github.com/jgertm/nrw.git && cd nrw
$ stack install --local-bin-path=$DIRECTORY_ON_YOUR_PATH
...

• Up and Down to navigate candidates
• Tab to select
• Enter to return selections and currently highlighted candidate
• Esc to exit

Because you'll never get through your reading list one item at a time!

$ find ~/papers/ -name *.pdf | nrw --mask='/([^/]+.pdf)$' | while read -r pf; do open $pf; done

No.

None of them display an aplomb lambda as the prompt symbol.
