Example:

printf "%s\n%s\n%s\n" alpha bravo charlie > example.txt
cat example.txt | checkline

You should see each line with a checkbox and text:

[ ] alpha
[ ] bravo
[ ] charlie

Move up and down in the list by typing arrow keys.

Check or uncheck any checkbox by typing space or return, such as:

[x] alpha
[ ] bravo
[x] charlie

Check each line that you want, then type ESC to finish.

The command outputs each line that you checked:

alpha
charlie

Install checkline as a typical Rust crate:

cargo install checkline

If people want other ways, such as with package managers, we welcome help to create these ways.

The purpose of this command is a simple picker, that is easy to use, and that work wells in on the command line such as within a pipe.

The purpose isn't intended to handle very long lines, or very long inputs.
