Hooray! I have a bunch of small utils that I use to make repl life easier. One thing I did to scratch an itch is a clojuresque lambda shorthand (cut on steroids) for guile. It transverses whatever expressions you put into it and rewrites it into a lambda where all identifiers of the form %n where n is an integer gets transformed into a lambda argument.
https://hg.sr.ht/~bjoli/megacut/browse (megacut (let ((a "Hello ")) (string-append a %1))) => (lambda (%1) (let ((a "Hello")) (string-append a %1))) Using read-hash-extend one can write #%: #%(apply + (/ 10 %1) %&) => (lambda (%1 . %&) (apply + (/ 10 %1) %&)) It supports arbitrary many arguments, and also allows for "ignoring" arguments: #%(display %3) => (lambda (%1 %2 %3) (display %3)) A regular % is also a shorthand for %1: #%(+ % %) => (lambda (%1) (+ %1 %1)) I use it daily. 20 minutes of scripting that the last year or so probably saves me at least 25 seconds of typing :) It has rudimentary unhygienic support for nesting, which may or may not be a terrible idea. I have another useful little function, port->list which takes a port and a read function and returns a list of whatever the reader function returns until the port EOFs. less powerful than port-fold, but less fuss to use when you just want a list. I leave that as an exercise for the reader, though. -- Linus Björnstam On Sun, 16 Feb 2020, at 15:56, Ludovic Courtès wrote: > Hello Guilers! > > Today, it’s been 9 years since Guile 2.0 came out! > > https://lists.gnu.org/archive/html/guile-devel/2011-02/msg00173.html > > It’s impressive how much has been accomplished since 2.0, and how what > seemed like a pipe dream back then came into reality with 3.0.
