Pythonista turned lisper.

https://lisp-journey.gitlab.io/pythonvslisp/

I run CL apps in production.

CL, batteries included, fast scripting: http://ciel-lang.org/

I create a Common Lisp course in videos. It's a progressive and structured course, where everything that was hard for me (especially hard to find) is made easy for you. Check it out! https://www.udemy.com/course/common-lisp-programming/?referralCode=2F3D698BBC4326F94358

Start here with Common Lisp 8-) https://lispcookbook.github.io/cl-cookbook/getting-started.h... To learn the language, look at the good books out there (Touretzky's etc).

ps: you don't need to learn Emacs. A terminal even is enough. See the Cookbook/ Editors section.

Don't miss out, we had new excellent editors and tools being released in the last months:

Mine: a complete, single-download application that comes with everything needed to experience the interactive and incremental development programming workflow, including hot-reloading and on-the-fly debugging. For CL and Coalton.

https://coalton-lang.github.io/20260424-mine/

OLIVE: a new hand-made plugin for VSCode.

ICL: a new REPL for the terminal and the browser with advanced features.

as a bonus: a JupyterLite kernel based on JSCL that runs 100% in the browser.

find them all: https://lispcookbook.github.io/cl-cookbook/editor-support.ht...

the python debugger is cool but is an inferior experience. It isn't only about a REPL, but about the editing experience, and about the language being thought from the ground up for long-living programs. See: https://mikelevins.github.io/posts/2020-12-18-repl-driven/

I like History but I'll comment about Lisp in web apps today, if I may. We have a choice of web servers and web libraries (https://github.com/CodyReichert/awesome-cl/#web-development), and we live in happy times where HTMX or Datastar are great fit for Lisp -as with any stack. See these Datastar examples built in CL: https://github.com/fsmunoz/datastar-cl I use and like the Mito ORM too, which comes with automatic migrations and, since last year, a composable query engine (SxQL).

Here you will find some screenshots of some of today's web applications built in CL: http://lisp-screenshots.org/ and here an opinionated tutorial: https://web-apps-in-lisp.github.io/ One example: ScreenShotBot https://screenshotbot.io/ a successful open-source product and company. It now replaced Facebook's automatic screenshot testing tool (source: their blog). So, web apps in Lisp are possible -with a right amount of learning time and elbow grease.

The incremental development and interactive top-level are still precious and unmatched.

The trap is using quote, with the list operator there are no issues:

    (defparameter *a* (list 1 2 3))
and of course, mutating top-level variables is bad style.

Notes on CL:

- why nothing on the "compiler" line? Everytime you load a snippet or a file with SBCL, it compiles it (to machine code). There's also compile-file.

- interpreter: likewise, all code is compiled by default with SBCL, not interpreted, even in the REPL. To use the interpreter, we must do this: https://github.com/lisp-tips/lisp-tips/issues/52

- command line program: the racket cell shows the use of -e (eval), the same can be done with any CL implementation.

- since the string split line introduces cl-ppcre, one could mention cl-str :D (plug) (much terser join, trim, concat etc)

- ah ok, for dates and times, flattening a list, hash-table literals… we need more libraries.

- more files operations: https://lispcookbook.github.io/cl-cookbook/files.html

- emacs buffers: now compare with Lem buffers 8-)

- posix-getenv: I'd rather use uiop:getenv (comes in implementations).

- uiop:*command-line-arguments*

- exit: uiop:quit

- uiop:run-program (sync) / launch-program (async)

- java interop: with LispWorks or ABCL (or other libraries)

Someone threw out a Zed LSP for Common Lisp with LLMs help: https://github.com/etyurkin/zed-cl It requires heavy compilation of the wasm toolchain so I finally didn't try it. It seems it doesn't have a lisp debugger.

more importantly, as you precise below, you edited (and somewhat corrected) the article after feedback from /r/lisp. So it isn't only AI output.

I myself run web-apps and scripts for clients. Didn't ditch Django yet but working on that.

+1 to explore Coalton. It's also talked about on this website and often by its authors.
