Static typing is not "obviously good"
The comparison is flawed. There are no advantages to driving without a seatbelt, but there are pros and cons to dynamic typing.
It's not necessarily about the time it takes to type the type definitions.
static typing leads to developers trying to represent the "real" world in a bunch of categories and arbitrary boxes. Thats not necessarily a good thing because you can loose much time in bike shedding discussions like "Is a person class still a valid person class if it has no Surname" which do not provide actual value to your product.

Any widely used modern editor/IDE will have plugins to do the same thing.
> True. But i do not want to install multiple several gigabyte sized bloatware gui behemoths apps just to develop some software.
Contextual completion as offered by modern IDEs or language servers is vastly superior to Ctags, and you don't have to home-cook anything to get it working.
> Also available in vim and doesnt need any home-cook solution. There are decent plugins that work out of the box for that kind of stuff
That's what SSHFS is for. No need to limit yourself to whatever happens to be installed on the remote machine. You don't even have to copy config files around.
> or more easily: just edit remote files directly via scp/ssh. Vim can do that.
we are talking pictures atm. not videos.
I bet you could get as good as SD with two weeks of free time, lots of youtube tutorials and with a photoshop license.
so, don't trust photos you see online?
That was i learned as a student 15 years ago when Photoshop was adapted by the masses.
Nothing changed, just the tools got even easier to use.
Just to leave some hints for people.
- If you don't want to deal with the JVM, Clojure also runs on the Web and .NET.
- If you develop with the REPL you don't have compile cycles
- Or just use Babashka (no compilation needed)
clojure adoption is slow but still increasing.
If you go by this logic any language that isn't the current most trending one is dead.
Clojure has it's niche as immutable lisp. That itself has not the broadest appeal but thats ok.
Clojure is definitely not dead.
There are active Clojure user groups in most countries (even in my little region) and i still (or even more than ever) stumble uppon cool and exiting projects and libs (e.g. https://github.com/borkdude. It's just incredible what a surplus value this dude alone provides to the ecosystem)
Clojure may not have the biggest audience but like others said, it generally focuses more on stability, so using libraries that haven't been updated a while is more of a plus-point and don't mean they are outdated.
Personally speaking, Clojure really brought back the joy of programming and i would never willingly go back to developing in a language without a REPL. The tight feedback loop you have while molding a running program in your editor and the constant dopamine drip feed it causes are just too addictive.
Languages that reach the maturity Clojure has never die, they become undying.
There are active Perl groups in some countries. Perl is so undying. Clojure less so, but...
It's a spectrum where Clojure neither has massive adoption (1.51% in SO's 2022 survey [0]) or rapid community growth (compared to hyped or massively adopted technologies).
Clojure is listed as the top paying language in StackOverflow's 2022 survey.
Clojure is an acquired taste. And it isn't a bad one, either!
> It's just incredible what a surplus value this dude alone provides to the ecosystem)
Seconded; it's pretty jaw-dropping!

Well-said -- I've been needing to write some Python recently, and it's only redoubled my preference for Clojure; the Python shell is a poor substitute at best for the Clojure REPL :(
I found it pretty easy to set up a Python REPL in VS Code, which would allow me to do similar things to the Clojure REPL such as highlighting some text in the editor and evaluating. All in all it was pretty close. I guess the only thing that is really different is that it was not connected to the same process I'm debugging, but a different python process. Is that the main thing you're missing?
Yeah, quite different. Technical as much as procedural and psychological.
In a Clojure REPL, you navigate "modules" like directories. And each directory has "files", or vars you've defined. Basically 'cd' and 'ls', but for module-level structures.
So you 'cd' to one "directory", query an AWS service or read a CSV file, and save results in that namespace ("my_namespace/my_results"). While you're at it, you save the results to a JSON file ('echo ... > tests/saved_results.json').
(You type this all into a REPL, no need to save this one-time command in a file. You can always re-run it by pressing UP like in bash.)
Then, you write a function called 'save_to_db()' in your text editor in the "database" namespace that accepts the input and writes to a database. You send that function to the REPL, and in the REPL, run the function on the results you saved from the first step in the var ("database.save_to_db(my_namespace/my_results)".
While you're at it, you 'cd' to your "tests" namespace in the REPL, and write a quick test in your test editor that parses 'tests/saved_results.json' and calls your "save_to_db" function and verifies the database. Send test to REPL (keyboard shortcut), run the test (another keyboard shortcut), fix the code, send updated code to REPL, rinse and repeat.
And this is all in one process, so you only "start up" Java once. Everything else is basically instant.
There's a ton of Youtube videos on using Clojure REPLs. It's really a game changer...
Yeah, that's it exactly. For me there's a power and an ease of flow that comes from having the REPL in the context of your running software, with access to program state and the easy ability to modify your code as it runs without having to restart anything or lose state, that's really unbeatable.
