pjb: Thanks for the clarification ! That would indeed be a fun projet to add such a read-only feature

I'm surprised to learn that append doesn't copy the last list, but it does make sense
1:50:31

APPEND, like most lisp functions, prefers to get the job done with the fewest copies

APPEND could get confused if it tried to copy something that isn't a list, e.g. in (append '(1 2 3) 'a)

(or at least, as if it used COPY-LIST to copy.)

Good morning everyone!

Why are older versions of quicklisp-installed packages kept around after upgrading?
9:12:04
madrik
By 'older versions', I meant the archives.

madrik: well, you can go back if the upgrade broke your software, or you can have different software on different versions of the quicklisp distribution

madrik: you can also use ql-dist:clean to clean them up

Xach: We've been running a "quickclasp" server to distribute stuff specific to clasp - it's been working well.

Anyone knows how to use this library? In particular, how to use #'digit? to parse a digit? https://github.com/Ramarren/cl-parser-combinators/blob/9c7569a4f6af5e60c0d3a51d9c15c16d1714c845/token-parsers.lisp

ah (monadic) parser combinators are powerful :)

nij: you mean beyond (parse-string* (seq-list? (digit?) (digit?) (digit?)) "123") ?
13:00:50
splittist
(which yields (#\1 #\2 #\3); nil; t; nil; and a hash-table )

Cool. It works. Next is to try to learn how it's implemented.. I feel like it's more advanced than my level.
