Clojurians Log v2

Thank you for all your work @pez and the rest of the Calva team!

Happy new year. Is there a list of Calva function names or some API docs? I'd like to add key bindings to VSpaceCode that call Calva functions. For example, defining , e f to evaluate a top level form by calling a function such as calva.evalCurrentTopLevelForm Alternative, I guess I could clone the Calva project and poke around and hopefully use auto-complere to discover function names. Thanks.

If you open the Calva extension in the Extensions pane, there is a tab there Feature Contributions and in there you find a section for Commands. Most commands take no arguments.

I’d be very interested in publishing any bindings you produce that way on http://calva.io somewhere.

Some (I guess most) shortcuts are contextual, using the when clause. I don’t know what VSpaceCode allows, but anyway, to find the when clauses, open the Keyboard Shortcuts pane and look for the commands.

happy new year !

is there a way to reload compiled classes in Calva? Right now I just close vscode, open and re-jack-in . I compile java classes with gen-class that I need to reload

or at least a command to restart and re-jack in without closing vscode ?

@eugen.stan happy new year from the Netherlands

Happy New Year, @eugen.stan! I’m not sure what it takes to reload compiled classes. But StackOverflow suggests to leave a (comment (compile '<http://name.space|name.space>)) in the file. Where the comment hides the compile command from itself. Then you should be able to use Calva’s Evaluate Top Level Form on that.

To restart the REPL, if it is started with Jack-in, you can use the Disconnect REPL command. I’m not sure that is going to stay like that, because it is a bit weird that disconnect also jacks out, I think. But what you can rely on to remain is that if you jack-in again, the process will start with jacking out. So I change my suggestion to “Just jack in again” 😃 .

New Year’s release of Calva, v2.0.144, with these changes: • https://github.com/BetterThanTomorrow/calva/issues/915 • https://github.com/BetterThanTomorrow/calva/issues/910 • https://github.com/BetterThanTomorrow/calva/issues/904 See these docs for info about loading current namespace in the repl window https://calva.io/output/#load-current-namespace

installling right now

are there here some people who work in linux ?

or wsl2

I work on linux

oke, I try to find out if there is a problem wth my setip or a problem in a crux tutorial

are you willing to try some code ?

@eugen.stan

sure

let's write here

expeciallty the entity-history part

with my it hangs and with the tutorial maker it works

oke

this works not on my computer and works on the computer of the maker of this tutorial

;; end::check[]

are you sure? code samples do not always work

yep, I talked with her the whole afternoon and we cannot solve it

ok, so i need the dependency and also the runing db?

please share the crux dependency line

oke

I have this on my project.clj file

:dependencies [[org.clojure/clojure "1.10.0"]
                 [juxt/crux-core "RELEASE"]]

does this help ?

Initially starting with just languageId, adding any when clauses if required

yep., it also seems to work on your computer

have you restarted you repl?

several times

you are using def and from what I kno that is not the best way to handle it

hmm

I'm using clojure 1.10.1

have you restarted your computer ? 🙂

nope

tried with java 11 also

thanks, im out of ideas

have you tried to run it from a main (outside of REPL)?

it does seem to be a setup issue

no, I do not know how I then can run it

give me a few minutes

take your time

do you have clojure / clj tools installed?

yep

when I try this :

(defn -main[](
            (crux/entity-history
 (crux/db node #inst "2116-01-01T09")
 :kaarlang/clients
 :desc
 {:with-docs? true})
            ))

(-main)

it stil seems to hang

you should not call (-main)

oke

I wil not doing anything till you say so

you could add an alias to run the main function https://stackoverflow.com/questions/11023762/leiningen-with-multiple-main-classes

?? I do not have any or only 1 main in this project

ok, then make leiningen run this main

(defn -main []
  (let [node (crux/start-node {})
        manifest {:crux.db/id :manifest
                  :pilot-name "Johanna"
                  :id/rocket "SB002-sol"
                  :id/employee "22910x2"
                  :badges ["SETUP"]
                  :cargo ["stereo" "gold fish" "slippers" "secret note"]}]
    (crux/submit-tx node [[:crux.tx/put manifest]])
    (crux/entity-history (crux/db node) :manifest :asc)
    ))

oke, how do I do that

in repl I see this output : #'tutorials.crux.jupiter/-main

you shuould define a :main https://leiningen.org/

(defproject <http://leiningen.org|leiningen.org> "1.0.0"
  :description "Generate static HTML for <https://leiningen.org>"
  :dependencies [[enlive "1.0.1"]
                 [cheshire "4.0.0"]
                 [org.markdownj/markdownj "0.3.0-1.0.2b4"]]
  :main leiningen.web)

define the ns that contains the -main function

https://github.com/technomancy/leiningen/blob/stable/doc/TUTORIAL.md#running-code

did :

(defproject practicalli/crux-demo "0.1.0-SNAPSHOT"
  :description "FIXME: write description"
  :url "<http://example.com/FIXME>"
  :license {:name "EPL-2.0 OR GPL-2.0-or-later WITH Classpath-exception-2.0"
            :url "<https://www.eclipse.org/legal/epl-2.0/>"}
  :dependencies [[org.clojure/clojure "1.10.0"]
                 [juxt/crux-core "RELEASE"]]
  :main tutorials.crux.jupiter
  :target-path "target/%s"
  :profiles {:uberjar {:aot :all}})

hmm, does not work

I have this in my file

(defn -main []
  (let [node (crux/start-node {})
        manifest {:crux.db/id :manifest
                  :pilot-name "Johanna"
                  :id/rocket "SB002-sol"
                  :id/employee "22910x2"
                  :badges ["SETUP"]
                  :cargo ["stereo" "gold fish" "slippers" "secret note"]}]
    (crux/submit-tx node [[:crux.tx/put manifest]])
    (crux/entity-history (crux/db node) :manifest :asc)
    ))

tutorials.crux.jupiter=> (require 'tutorials.crux.jupiter)
nil
tutorials.crux.jupiter=> (tutorials.crux.jupiter/-main)
Syntax error compiling at (form-init6925765827011711183.clj:1:1).

what does lein run give ? (put a println inside main fn

defn -main

I gave you the code above

lein repl

lein run

Gives

Can't find 'tutorials.crux.jupiter' as .class or .clj for lein run: please check the spelling.
Exception in thread "main" Syntax error compiling at (/tmp/form-init17099874963866708404.clj:1:74).

yep, and that one I use. the one you gave me

follow this guide in a new file https://github.com/technomancy/leiningen/blob/stable/doc/TUTORIAL.md#running-code

once you have that working, you can switch to your crux sample

chips, wrong file

this one works fine

can you try this one

(ns practicalli.earth
  (:require [crux.api :as crux]))
(def node (crux/start-node {}))
(defn easy-ingest
  "Uses Crux put transaction to add a vector of documents to a specified
  node"
  [node docs]
  (crux/submit-tx node (mapv (fn [doc] [:crux.tx/put doc]) docs)))
(crux/submit-tx
 node [[:crux.tx/put {:crux.db/id :kaarlang/clients
                      :clients [:encompass-trade]}
        #inst "2110-01-01T09"
        #inst "2111-01-01T09"]
       [:crux.tx/put {:crux.db/id :kaarlang/clients
                      :clients [:encompass-trade :blue-energy]}
        #inst "2111-01-01T09"
        #inst "2113-01-01T09"]
       [:crux.tx/put {:crux.db/id :kaarlang/clients
                      :clients [:blue-energy]}
        #inst "2113-01-01T09"
        #inst "2114-01-01T09"]
       [:crux.tx/put {:crux.db/id :kaarlang/clients
                      :clients [:blue-energy :gold-harmony :tombaugh-resources]}
        #inst "2114-01-01T09"
        #inst "2115-01-01T09"]])
(crux/entity-history
 (crux/db node #inst "2116-01-01T09")
 :kaarlang/clients
 :desc
 {:with-docs? true})

with me it hangs on the entity-history ?

See you did

sorry I lost it

but when I do you main now

I see this :

Caused by: java.lang.Exception: Cannot find anything to run for: practicalli.jupiter

sorry I don't have time to try out things

I think the last error is because you don't have a -main fn

oke, it worked now

I see hello

because I added a (print "hello) to the main

bu that on is not the code that fails on my computer

yeah, sorry I can't help you there

that is this code :

(crux/entity-history 
  (crux/db node #inst "2116-01-01T09")
 :kaarlang/clients
 :desc
 {:with-docs? true})

and with this code ;

(defn -main []
  (print "Hello")
  (crux/db node #inst "2116-01-01T09")
 :kaarlang/clients
 :desc
 {:with-docs? true}) 

I see hello and then a waiting cursor for a vey long time

If you can provide a complete project in a github repo that can be pulled down and the steps you take up until you have an issue, it may be easier for someone to help, so that you can be sure things are the same at least code-wise, and be able to know if it's some external setup issue.

There is a complete github repo and I already noticed that on 2 persons it worked and on my the same code does not work
