Hello, may I know what is a good way to rename keys in a hashmap from say an underscore version like - :lu_textΒ to a dash -Β `:lu-text` ? I saw there is clojure.set/rename-keys but I don't think that's what I want?


Have a look at clojure.walk namespace.


I realised that my use-case for this - jdbc has an inbuilt way to do this πŸ™‚ but thank you!


Take a look at the camel-snake-kebab library as well: πŸ™‚

I'm trying to clojure -Ttools, however I get -T is no longer supported

Sivaram Konanki14:07:40

I'm using clojure 1.11 alpha


update your version of the clojure CLI -- you need a prerelease


the clojure CLI != clojure


the clojure CLI can launch different versions of clojure

Sivaram Konanki14:07:00

My deps.edn, how to invoke tools


you need to update the command line program clojure, not any deps of your actual project

I can't find the official link to the prerelease install docs 😞


use the instructions at to download the latest prerelease version

Sivaram Konanki14:07:07

I tried with brew head it doesn't work


brew uninstall clojure
brew install clojure/tools/[email protected]


there may be other steps required depending on the history of your brew installation


but brew will usually tell you what to do

Sivaram Konanki14:07:55

It works, thanks. Brew upgrade doesn't upgrade to latest version for some reason


FYI, that version is buggy and there is now a :)


this is a prerelease so is not yet a stable version available to upgrade


as a prerelease, you may encounter bugs or unstable behavior - feel free to ask in #tools-deps or file questions at

Hi there, I'm trying to build a RN + ClojureScript + Krell application running in a windows machine RN project working fine, clj running on windows, but when trying to implement Krell, can't pass through this:

clj -M -m cljs.main -co "{:deps-cmd \"yarn\"}" --install-deps

Hugo Bonatto19:07:14

fails with Error building classpath. Specified aliases are undeclared: [:-m]

Hugo Bonatto19:07:15

in the first attempt, and subsequent attempts results in

Hugo Bonatto19:07:19

clojure doesn't come with cljs, you'd need to provide it as a dep - what does your deps.edn look like? also that command line looks wrong to me, -M should be immediately followed by some option flag

Hugo Bonatto19:07:11

I'm following this:

Hugo Bonatto19:07:30

{:deps {io.vouch/krell {:git/url ""
                        :sha "08f2bfea96aa48feb8511851e37f5948453986e5"}
        io.vouch/reagent-react-native {:git/url ""
                                       :sha "0fe1c600c9b81180f76b94ef6004c2f85e7d4aa0"}
        reagent/reagent {:mvn/version "0.10.0"
                         :exclusions [cljsjs/react cljsjs/react-dom]}}}


I'm surprised to not see cljs anywhere in there as a dep, and I have no idea what -M should or would do in a command line when it's followed by -m


that is, in both cases I think the tutorial is wrong


@hugo147 compare to this from the clojurescript quick start:

clj -M --main cljs.main --compile hello-world.core --repl


but in their case they also add clojurescript to the deps.edn

Hugo Bonatto19:07:00

for windows, they request to run from cljs.jar

Hugo Bonatto19:07:13

which may ignore my deps.edn


but you didn't specify cljs.jar on your command line and the error is that cljs.main wasn't found
