Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Writing Small CLI Programs in Common Lisp (2021)
and for CL: https://github.com/ciel-lang/CIEL/ (pre-alpha) CL with many batteries included (json, csv, http, CLI parser…) so the scripts start fast.

Sharpscript: Lisp for Scripting
As a CL addict, this isn't unlike Babashka: fast-starting CL scripting with batteries included. https://github.com/ciel-lang/CIEL (alpha) (otherwise the solution is to build a binary)

It's 2023, so of course I'm learning Common Lisp
> lots of interoperability libraries
That's true. For cases when you want to start with a good set of libraries (json, csv, databases, HTTP client, CLI args, language extensions…), I am putting up this collection together: https://github.com/ciel-lang/CIEL/ It can be used as a normal Quicklisp library, or as a core image (it then starts up instantly) or as a binary.
It can run scripts nearly instantly too (so it isn't unlike Babashka). We are ironing out the details, not at v1.0 yet.
> handling a runtime error by just fixing the broken code--in-place, without any restarts [from the blog]
Also (second shameless plug) I should have illustrated this here: https://www.youtube.com/watch?v=jBBS4FeY7XM
We run a long and intensive computation and, bad luck, we get an error in the last step. Instead of re-running everything again from zero, we get the interactive debugger, we go to the erroneous line, we compile the fixed function, we come back to the debugger, we choose a point on the stackframe to resume execution from (the last step), and we see our program pass. Hope this illustrates the feature well!

Improving REPL experience in terminal?
check out CIEL, one of it's goal is to be a quality terminal repl

networking and threads
I've been doing the protohackers challenges in common lisp to learn, and I ran into a problem that is possibly a bug in the socket library, or much more likely in my misunderstanding it. At any rate the best workaround a found seems pretty ugly, so can anyone advice what would be the cleanest way to solve it, and how we're supposed to deal with sockets? The problem is basically make a tcp server, that forwards all connections to an upstream server, and does a regex find and replace on all the traffic that passes through. Here's my working solution. I haven't learned much how asdf and packages work yet, I am just using CIEL which is SBCL (2.2.9.debian) with a bunch of libraries already loaded, I think if you load usocket, usocket-server, cl-ppcre, and bordeaux-threads it should run. The program is simple, I just forward all traffic from the client to the upstream doing regex replacement on each line, and spawn a thread that handles forwarding all traffic from the upstream to the client with the regex replacement. The issue is that when the client disconnects, my program doesn't disconnect from the upstream, even when I call (close upstream) and (socket-close socket). Before closing the socket or stream, the connection shows as established in ss -tp and as belonging to the sbcl process. After calling close on the socket and stream, the connection still shows as established, just it no longer shows as belonging to the sbcl process, and tcpdump shows that the 4-way termination handshake is not sent. After killing the background thread that is also reading the same socket, the 4-way termination is sent, and the connection is closed. It seems like calling close on the stream or socket should close it? Are sockets or streams not safe to share between threads? Is there a cleaner way to handle closing the upstream connection when the client disconnects rather than calling destroy thread?

Common Lisp Implementations in 2023
I quite agree, so I'm making a meta-library to have useful libraries available out of the box: https://github.com/ciel-lang/CIEL/ It's CL, batteries included. You can use it as a library, as a core CL image (loads up faster), and as a binary to have a REPL, and to run scripts:
ciel --script myscript.lisp

Babashka: GraalVM Helped Create a Scripting Environment for Clojure
No, we have to build a binary, which starts up super quickly.
I began to put together a "distribution" of useful CL libraries for everyday tasks: https://github.com/ciel-lang/CIEL/ It comes as:
- a lisp core, which you can use in your editor setup instead of sbcl or ccl, the advantage is that it loads instantly with all these libraries built-in (instead of quickloading all of them when needed)

Any projects want/need help?
Hi there. I'd enjoy help on anything web development for openbookstore: https://github.com/OpenBookStore/openbookstore (especially now: setting up i18n) Or, we could work on the terminal REPL experience for the CIEL meta-package: https://github.com/ciel-lang/CIEL/ We could use a better base like cl-repl or better yet, Lish.

BTW, Roswell makes it easier to run scripts: https://github.com/roswell/roswell/wiki/Roswell-as-a-Scripti...
It is also a tool to install various CL implementations, and to install software.
It doesn't come with a choice of built-in libraries.

is ~/.roswell/init.lisp a documented feature?

Project and EDE: A potential way to organize project types?
You could also be a roswell user, in which case your project might have a roswell directory. Again, you can look at the qlot project for reference.

Create a Common Lisp Web app using ningle
Clack is a web application environment for Common Lisp inspired by Python's WSGI and Ruby's Rack. Clack provides a script to start a web server. It's useful when you deploy to production environment. You need to install Roswell before as Clack depends on it.

Examples of "short" (~300 lines or less) or longer sysadmin/devops scripts in Lisp?
w.r.t to image size, ScriptL takes care of that since everything is in the same image. You could also use something like buildapp or cl-launch to make a multi-call binary that you compile your scripts into. I think I recall roswell allowing multiple entry points too, but I never could get it to work. Possibly PEBKAC on my end.
