do little things count? because i made a little thing. i'm not a big fan of using repls for messing around because i want to go back and redo things all the damn time. recently i caught myself opening a text editor and doing

watch -n1 some-script

in a separate window. so i went ahead and made a little (vim)script that does just that - it automatically reruns your code as you type. it's been pretty convenient for doing little bits of napkin math. https://mastodon.social/@Ezhik/112830950176229170 https://bsky.app/profile/ezhik.bsky.social/post/3kxv2cusodm27

My go-to medium for such things is Emacs and its org-mode. You can put code snippets in org files and run (or re-run) them by typing Ctrl-C Ctrl-C. Perfect for little experiments, and works with dozens of languages.

See also entr for watching files & re-running arbitrary commands. P.S. Be a bit mindful of side effects incomplete code can have, may need some defensive habits... (One habit somebody taught me is only type

-rf

at the very end of

rm

commands, just in case I accidentally press Enter before I finished.)

definitely not writing any code with side effects in this but actually would be good to have some nicer safeguards beyond "don't do this"
