Re: [?] Adding my own function to clojure.core namespace

[Kurt Harriger]

You might also have a look at a library called vinyasa
 

> https://github.com/ardumont/vinyasa

You can can add it to your lein profile to copy functions into clojure.core 
and prefix them.  
The prefix makes it very clear that these are not part of standard 
clojure.core. 

(inject 'clojure.core '>> '[[clojure.repl doc [source source]]]) 

;; => will create the var #'clojure.core/>>doc and #'clojure.core/source

Note that the reader doc (https://clojure.org/reference/reader) says that
"Symbols beginning or ending with '.' are reserved by Clojure". It's not
enforced of course, but it might break things. It might be a good idea to
use some other single char prefix.

Re: [?] Adding my own function to clojure.core namespace

[Gary Fredericks]

For clojure (not cljs, yet) I proxy all the dev utilities I might want to 
use in a namespace called `.` so I can refer to it everywhere no matter 
what the local namespace setup is:

Re: [?] Adding my own function to clojure.core namespace

[Philos Kim]

I have another question. Debux library supports ClojureScript as well. 
Similarly, I want to add my own function or macro to cljs.core as in Clojure. 
Can I use the same strategy in ClojureScript as in Clojure if I use it in the  
ClojureScript source code, not in REPL?

The normal solution to this is to have a development namespace and a
production namespace that serve as entry points for your application.
During development you load in the dev namespace, and in production the
prod namespace will contain the -main function that starts your application.

You can omit the development namespace and anything it requires from the
production classpath when you compile the jar.

Do you intend to use this library from REPL or from the code itself?
If former, you can add the library to Leiningen (or whatever) REPL environment.
If latter, how do you enable/disable the debugging code in production? You can
use the same way for requiring/not requiring library.

There is no difference.

Regards,
Mikhail.

Re: [?] Adding my own function to clojure.core namespace

[Philos Kim]

Thanks both of you!

I know it is not desirable but it is sometimes needed, especially in my case.

For example , I wrote debux ( https://github.com/philoskim/debux ) 
library. I want to use it only in development, not in production. If I 
'require' debux in source code to use it in development, I have to remove it in 
the source code manually in production.

I tested your recommendation in REPL and it worked. However could you tell me 
about how I can implement it in source code form, not in REPL?

Re: [?] Adding my own function to clojure.core namespace

[Andy Fingerhut]

I would echo the question "is it truly a good idea?"

You can do it, but typing a single :require clause in an ns form once, and
then copying and pasting to other places that you use functions defined in
that namespace, is likely to be less time-consuming in the long run.

Re: [?] Adding my own function to clojure.core namespace

[Mikhail Gusarov]

Hello Philos,

It's no different to adding a function to any other namespace:

% clj
Clojure 1.9.0
user=> (ns clojure.core)
nil
clojure.core=> (defn foobar [x] (str "foobar " x))
#'clojure.core/foobar
clojure.core=> (ns user)
nil
user=> (foobar "12")
"foobar 12"
user=> foobar
#object[clojure.core$foobar 0x43b6123e "clojure.core$foobar@43b6123e"]
user=>

However is it truly a good idea?

[?] Adding my own function to clojure.core namespace

Is there any way to add my own function to clojure.core namespace? Because I
