Please make cljs-clomacs. about clomacs HOT 8 CLOSED

Ok, could you explain to me more about your desired workflow?

Clomacs is made to be a wrapper of Elisp to Clojure calls and vice versa.
So, if you want to call some Clojure code from Elisp, you should create a wrapper:

(clomacs-defun get-property System/getProperty)

Then you can operate with get-property as ordinary Elisp function.
If cider-current-connection exists, then

(get-property "java.version")

will return the result immediately. If not, it will start nREPL and evaluated after process started.
If you want to see the result of this evaluation add nrepl-ready-callback param (literally on nREPL started and Clojure function evaluated hook, do with this function evaluation result):

(clomacs-defun get-property2
               System/getProperty
               :nrepl-ready-callback (lambda (result)
                                       (message "nREPL started, property value : %s" result)))

Here get-property2 will operate the same way as get-property does for "REPL already started" case, but will echo the message after nREPL starts when it called without nREPL already started.

If you want to call a chain of wrapped functions, e.g.:

(message "Running Java %s on %s system"
         (get-property "java.version")
         (get-property "os.arch"))

you must be sure that nREPL is already running. If not, clomacs will start 2 nREPLs (!!!), each one for every get-property calls. To avoid this, please use clomacs-with-nrepl.

(clomacs-with-nrepl nil
  (lambda ()
    (message "Running Java %s on %s system"
             (get-property "java.version")
             (get-property "os.arch"))))

This function makes sure, nREPL started and then evaluates it's lambda as callback.

So, actual clomacs functions to use are: clomacs-defun and clomacs-with-nrepl.
You are not expected to use clomacs-launch-nrepl or clomacs-jack-in-cljs directly.

If you need to start nREPL for ClojureScript, please add :backend :cljs key parameters for clomacs-defun and clomacs-with-nrepl calls, e.g.:

(clomacs-defun get-property3
               System/getProperty
               :backend :cljs)

The most expected use case is to create a dedicated leiningen project for your Elisp+Clojure mixed Emacs extenstion and eval all functions in it's REPL. The name of project passed by :lib-name parameter for clomacs-defun macro and first parameter for clomacs-with-nrepl function.

I've added org-mode Babel experiments file to cm-test project:
https://raw.githubusercontent.com/kostafey/cm-test/master/org-sandbox.org

The exception you see here: No such var... in this case actually means that it's namespace hasn't required yet. To accomplish that you can require it manually (e.g. via clomacs-require):

#+begin_src emacs-lisp :noweb yes
(require 'clomacs)
(clomacs-defun cm-test-md-to-html-wrapper
               cm-test.core/my-md-to-html-string)
(clomacs-with-nrepl nil
  (lambda ()
    (clomacs-require `'cm-test.core)
    (message (cm-test-md-to-html-wrapper "# Hello, World!"))))
#+end_src

But the most straightforward way is to use :namespace parameter for run require in macros:

#+begin_src clojure
  (ns cm-test.core)
  (use 'clomacs)
  (defn add [x] (+ 1 x))
  (add 2)
#+end_src

#+begin_src emacs-lisp :noweb yes
  (require 'clomacs)
  (clomacs-defun cm-test-md-to-html-wrapper
                 my-md-to-html-string
                 :namespace cm-test.core)
  (clomacs-defun cm-test-add
                 add
                 :namespace cm-test.core)
  (clomacs-with-nrepl nil
    (lambda ()
      (message (cm-test-md-to-html-wrapper "# Hello, World %s times!")
               (cm-test-add 2))))
#+end_src

Furthermore, please note, that this org-mode file shoud be located in your Clojure project folder with cm-test.core namespace.
If not, you should pass :lib-name parameter to clomacs-defun and to clomacs-with-nrepl as a first argument. This lib-name is a Emacs Lisp library file which ends with (provide '<lib-name>) and is available in Emacs load-path. This Elisp file sould be located in your Clojure project which namespaces you use in clomacs-defun(s).

@PlumpMath any suggestions about API?
What do you think about, e.g. :backend parameter

(clomacs-defun get-property System/getProperty :backend :cljs)

with a default value of :clj.

Can you write this fantastic project as a lumo?
.
This project Fantastic.

Above link very fast.
Would be more cool dynamic loading modules.

hanks.

When I was a kid, I read the Macro command book of autocad 10? 11? book (dos version) to be good at computers. Why did I think it was such a humble macro system?
.
today, I feeling.. recently I've been windows remove and setting up my computer... with guix os, exwm, org-mode... and I've memoried your clomacs Project!
.
I've been thinking that we can now save all of our moments as a card macro on the keyboard.
If you combine the backend(all language) interoping elisp. of this great project with elisp to store all of our moments,
we will be able to catch every moment of memory that we have on the keyboard day of day life.
Thanks! human alien. :) oh Thanks!

@kostafey

There are currently src and project.clj in the home directory.

I want to work with only one nREPL on when the emacs boot up.

I used to work with a cursor-nREPL turned on with the command below.
I'm looking at the og-babel emacs-lisp block With clomacs.
Two and three... NREPL is running.. I don't want to increase the cider.

(require 'clomacs)
(clomacs-launch-nrepl nil t) ; not currently operational.

You know how I work, and you've created the function below.
Thank you.
previous function (clomacs-launch-nrepl)..
There was an error in clomacs-launch-nrepl, so I looked up the code.
I need four factors.

for the new generation
(clomacs-jack-in-cljs fn.) <---?
I think we can solve it with the above function,
I'm not sure how to use it. I don't know the complicated elisp.
How can I get clomacs-cider to work with one nREPL?

Thank you.

from clomacs.

Thanks Very Much! @kostafey
:)

I start ( screenshot right side codes).

(org-babel-load-file "~/CLOM/README.org")

Previously on this code alone,
"(require 'clomacs) (clomacs-launch-nrepl nil t)"
So I use
nREPL load... static-project(CLOM) code.
It was shared to README.org (org-babels).

Of course, I elisp code was also first (provide 'CLOM) by README.org.
emacs read the follow first. (NAME change cm-test to CLOM;;; and lib-name/namespace clomacs to CLOM
https://github.com/kostafey/cm-test/blob/master/src/elisp/cm-test.el
Those .elisp codes are Picked up from your other repository cm-test project.

Then emacs had all the REPL codes shared.

Thanks @kostafey
👍

I'm putting together the clomacs lein project in my job project,
so the org-mode can't... because I'm so busy in a hurry job-project. I'll try it later and leave comments if it goes well.
Thank you very much for making it.
