Packaging is made much easier due to that. + +The good thing is that the program itself is small enough ([119 lines][119-lines] on v0.1.0) that POSIX sh does the job just fine, combined with other POSIX utilities such as [getopts][getopts], [sort][sort] and [awk][awk]. + +[119-lines]: https://euandre.org/git/remembering/tree/remembering?id=v0.1.0 +[getopts]: http://www.opengroup.org/onlinepubs/9699919799/utilities/getopts.html +[sort]: http://www.opengroup.org/onlinepubs/9699919799/utilities/sort.html +[awk]: http://www.opengroup.org/onlinepubs/9699919799/utilities/awk.html + +The behaviour is: given a program that will read from STDIN and write a single entry to STDOUT, `remembering` wraps that program, and rearranges STDIN so that previous choices appear at the beginning. + +Where you would do: + +```shell +$ seq 5 | fzf + + 5 + 4 + 3 + 2 +> 1 + 5/5 +> +``` + +And every time get the same order of numbers, now you can write: + +```shell +$ seq 5 | remembering -p seq-fzf -c fzf + + 5 + 4 + 3 + 2 +> 1 + 5/5 +> +``` + +On the first run, everything is the same.
