Eric Normand on REPL-driven development in Lisp and other languages:
The REPL accelerates learning by increasing the speed and information richness of feedback.
[...]
Fast, rich feedback is essential to achieving a flow state.

Who in the world though it a good idea putting their custom readtables into libraries intended for outside use? I don't want your hash table syntax, I want MINE. Don't pollute the readtable and other aspects of someone else's image if you're providing a library. The library you're making should be portable and clean #CommonLisp, not some unreadable #DSL you use in your #REPL. It's fine in the REPL, but not in libraries. Keep it clean. Simple courtesy.
Not pointing fingers, but everyone doing that shall be ashamed.
I have a #TypeScript codebase that I would love to work with interactively, in a #REPL. What are my options?
I just discovered Jshell, a Java REPL shell. It's like Python's interactive shell , but in Java ;-)
It's not new. Jshell was introduced in ... Java 9. Shame to me I only learn about it in Java 23!

I think it ended up pretty interesting, and what you would expect. The repl is a better interactive experience, but the noweb tangle optimizes in ways the separate repl lines can't, and is already in a disk-persisted file.
Looking forward to feedback and commentary ( @ksaj ;p)
Your web server having an interactive shell (REPL) where you can live update entries in your site/app’s database is pretty neat (if I do say so myself) :)

(I’m porting the Small Technology Foundation site¹ from Site.js² – and hence from being a static site generated via Site.js’s integrated Hugo³ – to Kitten⁴. In the process, I’m creating an admin panel⁵ for the news, events, and videos sections, which will make them easier to update, and storing the data in Kitten’s internal JavaScript Database⁶.)

² https://sitejs.org
³ https://gohugo.io/
⁴ https://kitten.small-web.org
⁵ It’s trivial to create authenticated routes in Kitten. You just add a lock emoji (
) to the end of your route’s name. e.g., admin.page.js or /admin/index.page.js (see https://kitten.small-web.org/reference/#sessions-and-authentication).

So my question is, what's an intuitive way to use dropping-in- #fortran from the #lisp #repl ?
Reading a .f file ~ into a let* form which I'm currently doing seems kind of bland. #f( this(1) = is(2) + a / fortran * line) seems kind of uninspiring (who would want to express themselves like this). Maybe Enter "fortran mode" and read lines of fortran from *standard-input* with normal interactive evaluation hacked in?
The fortran becomes #series expressions in lisp.
Guix Social next Thursday (January 16th). There will be a talk by @abcdw about his Guile Scheme IDE for Emacs, and the underlying Nrepl project that can be used by any editor. For all the details:
https://www.meetup.com/guix-social/events/304634420/
Andrew also has many other projects, including RDE an extension to Guix. Come along and ask him questions!
Despite ample evidence to the contrary, #Ilive (hmm, if I were also #evil, that would be a pallindrome as well as a visual collision)

I am enormously happy with the
{ verb [ dobj [ prep iobj ] ] } x
language dynamic, and how it shares your #lisp #repl, and their concerns are just... Different so they don't collide.
I guess I get my #languageDesign friends a little better now.
Thoughts?
Do you want to learn how to create beautiful and useful #REPL for your #ProgrammingLanguages written in #Haskell? I wrote a Haskeline tutorial just for you: https://abhinavsarkar.net/posts/repling-with-haskeline/

Python 3.13 has been released 
Python 3.13 is the latest stable release of the Python programming language, with a mix of changes to the language, the implementation and the standard library. 
The biggest changes include:
- a new interactive interpreter
- experimental support for running in a free-threaded mode
- a Just-In-Time compiler
Read "What’s New In Python 3.13" 
https://docs.python.org/3/whatsnew/3.13.html
Just added basic server/process stats to Kitten’s interactive shell (REPL).
Use the new `.stats` command to see them.
Also, documented the shell better in the Kitten Reference:

Łukasz Langa is giving the closing keynote of the EuroPython 2024 conference, entitled "Live coding music with PyREPL in Python 3.13" in Prague

Another #pandoc #Lua #REPL tip: write the below Lua code to a file `panglob.lua` and call pandoc with
pandoc lua -l panglob -i
to turn all pandoc module functions into global variables. This allows to type `Pandoc('hi')` instead of `pandoc.Pandoc('hi')`.
for k, v in pairs(pandoc) do
_G[k] = v
end
Move `panglob.lua` to a directory in your LUA_PATH to make it accessible from everywhere.
w00t! 
#Kitten now has a shiny new…
kitten shell
…command you can use to connect to your Kitten daemon in production to debug it, etc.
Also, I don’t know if I missed something simple but I had a hard time handling Node’s #REPL preview completions over a socket connection. Couldn’t find any docs. Managed to fix it by implementing a control channel to communicate the remote client’s terminal size. Wrote it up here, in case it helps anyone else:
https://codeberg.org/aral/gists/src/branch/main/node-js-repl-over-socket-with-preview-completions.md
You can now connect to the interactive shell (REPL) of a Kitten daemon running in production by sshing into your machine and running:
telnet 127.0.0.1 1337
(Or nc 127.0.0.1 1337 if you prefer. Basically, it is available from port 1337 on the local loopback address.)
In development mode, you can press the s key to start up an interactive shell.
New Video – Kitten features introduced this week:
• Interactive Shell (REPL)
• Multi-page Settings
• Backup and restore (data portability)
With examples that cover components and Kitten’s built-in JavaScript database (JSDB).
Kitten’s interactive shell (REPL) now saves session history scoped to your app so it will still be there when you next serve the same app.
https://codeberg.org/kitten/app#kitten-s-interactive-shell
I think I’m done with the REPL feature now.
Going to take a little break, step away from the computer, and make a plan for the next week of work on Kitten and Domain¹.
Small update on Kitten’s new interactive shell (REPL). You can now access Kitten’s router via:
kitten.app.router
Also updated the section in the tutorial to fix typos in some of the code examples and use the new router key path:
