If you haven't already, see Sean's presentation at London Clojurians https://www.youtube.com/watch?v=gIoadGfm5T8

The slides are at https://corfield.org/articles/REPL-Driven-Development.pdf

If a function definition has changed (in a file), just re-eval that function in the REPL. If you do that every time you make any changes, the REPL state will be in sync with the file state.

Similarly, if some data file has changed, re-run any functions that maintain any state that depends on the changed data.

See https://clojure.org/guides/repl/enhancing_your_repl_workflow#writing-repl-friendly-programs as well.

thank you both for explaining

I don't "reload a webapp" -- I just eval the changed code into the REPL.

so you change the code in your editor and re-eval immediately

yes that's a great way of workin

Every time I change a function I hit a hot key that does "eval top block" so the new definition is in the REPL, and I use #'func references instead of func so that passing functions as HOF will pick up the new version automatically (per that http://clojure.org page).

No "reload", no "refresh", no file watchers. Always eval everything into the REPL from your editor as you work. That's how my REPLs stay up and running for weeks.

could you explain the #'func bit? where should i use that instead of func ? whenever a function is passed ?

Read the link I posted.

(it's explained better there than I can)
