Then tell me how do you split a string by delimiter in CL? (Without using libraries, don't be a pajeet)
That's what I thought

So you think Common Lisp is better than Python

Don't abuse Satania-chan like that.

C/C++ string handling is fairly easy. It’s the built-in functions that are AIDS.
How do you do it in python without importing anything?
You can use the string method "split".
Yep, method. Everything in python is an object, including a simple string containing the word "Black person".
I will never forget the day I stop hating OOP. Learn python was by far the best decision I made in my career.
'wiener-sucker'.split('-')
can python do this
echo "56,http://link,data with,with a comma" | perl -nE 'my$l=join "t", split /(?<!\),/;print+$l=~s/\,/,/gr'
56 http://link data with,with a comma
i kneel
we don't even have while loops how could we ever compete
we do though
???
(loop while condition do stuff)
I can't tell if this is a troll post or if you actually think CL can't manipulate strings? Or is it because unlike in Python it requires a bit of brainpower to use substr and position functions?
oh wow he can split a string without importing a library because that function just happened to be included! what a gay kek
now try doing literally anything nontrivial without importing libraries and suddenly the entire appeal of python crumbles.

Then tell me how do you get a fixed-width integer? (Without using libraries, don't be a pajeet)

(ql:quickload :cl-ppcre)
And just use regex. If you want a solution that doesn't involve external libs, let's use csv as an example:
* (defparameter *csv-readtable* (copy-readtable))
(set-syntax-from-char #, #Space *csv-readtable*)
(defun read-csv-line (string) (let ((*readtable* *csv-readtable*))
(with-input-from-string (stream string) (loop for object = (read stream nil nil) while object collect object*~~)
>cl-ppcre
why not uiop:split-sting ?
You could do that too. I was also trying to remember if Alexandria has a string-splitting util but didn't feel like looking it up.
Here's the one I just did
(defmacro while (expr &rest block)
`(tagbody
loop
(if ,expr
(progn ,@block (go loop*~~))
(defun split (sep str)
(let* ((start 0)
(end 0)
(substrings (list nil))
(ptr substrings)
(len (length str*~~
(while (< end len)
(while (and (< end len)
(not (char= sep (aref str end*~~)
(setq end (1+ end*~~
(setf (cdr ptr) (list (subseq str start end*~~
(setq ptr (cdr ptr))
(setq start (1+ end))
(setq end (1+ end*~~
(setq substrings (cdr substrings))
substrings))
(princ (split #space "one two three"))
(terpri)
Can someone rate this? honestly
just realised that we can return directly (cdr substrings)
It is better.
- far more efficient
- can actually distribute binaries to customers
- has a standard
- has multiple up to date implementations
- is academically interesting
- has better books
