I’m asking an emacs question here out of desperation. I’ve used paredit-slurp for years, and it always added an extra space between the 2 items. Not anymore. Now, after slurping, I have to add the space between the items on either side of the point. Any ideas how that can be change? This is a feature obviously used all the time in Clojure mode, and it has become a huge annoyance.

if Clojure has gen-interface& gen-class and Java source files are merely an intermediate step to bytecode, which Clojure can generate anyway, why do some Clojure projects include Java source files ? Why not generate that bytecode from Clojure ?

hi, I have a data structure like this: [{:title "thing" :content "test" :tags [:tag1 :tag2]}, {:title "thing 2" :content "foo" :tags [:tag1] (this isn't the real data, but it is the real structure) and I'd like one like this {:tag1 [{:title "thing" :content "test"},{:title "thing 2" :content "foo"}] :tag2 [{:title "thing" :content "test"}]} . how would I do this in clojure? (context: I have a list of pages for a website and I want a list for each tag of which pages have that tag)

@nihilazo Depending on how fussed you are about extra tags in the rearranged data:

user=> (def pages [{:title "thing" :content "test" :tags [:tag1 :tag2]}, {:title "thing 2" :content "foo" :tags [:tag1]}])
#'user/pages
user=> (group-by :tag (for [page pages tag (:tags page)] (assoc page :tag tag)))
{:tag1 [{:title "thing", :content "test", :tags [:tag1 :tag2], :tag :tag1} {:title "thing 2", :content "foo", :tags [:tag1], :tag :tag1}], :tag2 [{:title "thing", :content "test", :tags [:tag1 :tag2], :tag :tag2}]}
user=> 

If you really don't want :tags or :tag in the results, you'll need to do a bit of cleanup.

Using (-> page (assoc :tag tag) (dissoc :tags)) instead of (assoc page :tag tag) gets you part of the way. Removing the :tag from each page after you've grouped them is a bit more work.

ah, thanks! I did not know group-by exists, that is a very useful function!

Is nrepl still the way to go if I want to embed a socket REPL in my application, or does Clojure 1.10 have this ability built-in now?

Looks like there is: https://clojure.org/reference/repl_and_main#_launching_a_socket_server

@cpmcdaniel The Socket Server was added in Clojure 1.8. It's a bare REPL so you cannot connect an nREPL client to it.

There is also prepl - anyone using that?

I've got a file that requires all other files and calls the function run-all-tests. Currently, in Calva, I can execute that file by pressing CTRL+`ENTER` and in Intellij/Cursive I usually open the file and hit SHIFT+`CMD`+`L` to load the file in the REPL to execute the tests. What bothers me is that in either way I leave the current file and it involves multiple steps. Do you know a better way of doing this or how to set a shortcut in either Calva or Intellij/Cursive that executes all tests?

I think Conjure uses that (prepl).

@simon.zachau No idea how to do it in Calva or Cursive, but I'm pretty sure CIDER supports that in Emacs and I know Chlorine supports it in Atom (since I use that).

@seancorfield thanks! I think there must be a way in Intellij/Cursive because I used it a few years ago, but I don't remember it 🙈

If you can bind hot keys to arbitrary code execution, you can do it -- that's how I customize stuff in Atom (so I have a hot key that runs tests in the test ns associated with the src file that I'm currently in, for example: so when I'm editing foo.bar, I can hit ctl-; X and it requires foo.bar-test or foo.bar-expectations and then runs the tests in whichever require was successful).

I think Conjure is moving away from prepl

@mauricio.szabo in favor of?

It has. It's now uses nrepl

@borkdude I believe nrepl, as @dharrigan said :)
