Re: lein midje not working

2018-04-11 Thread Renata Soares 
I found the problem... in my core.clj i was using (slurp *in*) to get 
contents via stdin. 
'lein midje' performs 'lein run' first?

The contents of your $HOME/.lein/profiles.clj file can affect the behavior
of all 'lein' commands run from any project, if you have one.

RE: lein midje not working

Do you mean you type `lein repl` and you don’t get a prompt at all? It just 
hangs before then?

I tried to reproduce based on the information below and it seems to work for me:

It happens with 'lein repl' too (gives timeout in this case).

Re: global-hierarchy.. private?

2018-04-11 Thread Francis Avila 
I'm not certain I know what use case you're getting at. It sounds like you 
want to take the current state of the global hierarchy and "fork" it into a 
private hierarchy? Even though the var is private you can still access its 
value:

@#'clojure.core/global-hierarchy (same as (deref (var 
clojure.core/global-hierarchy)))

I think you are already aware you can make and use your own hierarchies: 
all multimethod-related functions have an optional argument to accept a 
hierarchy directly as a value (or in a mutable ref container such as a var 
or atom in defmulti's case).

So to "fork" your own hierarchy, grab a snapshot the global-hierarchy var's 
value and use the derive and underive on that value to make your own 
hierarchy. Note that the heirarchy-explicit arities of derive and underive 
are pure: they return the new hierarchy map and do not mutate anything. 
(You also don't have to use namespace keywords for the type names.)

I hope you are not talking about something like a "live fork", where you 
want your own hierarchy expressed as a diff against the global-hierarchy 
and updated when the global hierarchy's value changes? You can probably do 
that with enough ILookup magic or a var watcher to recompute the derived 
hierarchy, but that sounds like a bad idea in general. Hierarchies are only 
useful with the named multimethods that explicitly use them, so it's hard 
to imagine a case where you want a multimethod to be "global hierarchy plus 
changes" and not just an entirely separate hierarchy.

Re: Anyone spent time with Kawa Scheme?

2018-04-11 Thread Didier 
Haven't tried Kawa, and my only other Lisp experience is Emacs Lisp.

That said, I think Clojure as a Lisp differentiate itself from other Lisps in 
that all its data-structures are built on abstractions. They default to be 
immutable in a performant and low memory profile way. Its got great added 
concurrency constructs like STM, CSP, Atom, Futures, Promises, Delays, etc. Its 
syntax includes very convenient default data-literals that has contributed to 
it having a culture of data-driven logic. EDN is great for serialization of 
code and data. It has powerful support for lazy evaluation, as well as strict. 
Finally, its interop with Java is excellent.

So, I don't know much about scheme and Kawa, but I suspect you'd have to build 
a lot to get all this back.
