Re: How to coerce to bigint ?

[Jens Bendisposto]

Just for the records You can still use auto-promotion with primed 
operators like *', +' etc. 

=> (* 10 100)

java.lang.ArithmeticException: integer overflow

=> (*' 10 100)

1000N

[ANN] avi 0.1.6 (searching)

[Jason Felice]

In this version:

* Fix for `O` on a blank line (Thanks to Anthony Garreffa!)
* Command history for the `:` prompt (using ^N, ^P)
* Implement `/`, `?`, `n`, `N`
* Refactored to compose most of the editor in a middleware pattern

avi

A lively vi.
Vision

We love vim. We want more! Test coverage. Flexibilty. Live REPLs!
Guiding Principles

   - Test driven. All functionality covered by tests.
   - Don't defeat vim muscle memory.
   - Code is for people. Be expressive as hell.
   - Be friendly. Especially to noobs.

Contributing

We track upcoming work on a Trello board .
This board has many small things that are easy to pick up, and we'd love to
see you.

I (Jason Felice) would love to walk through the code with you pretty much
any time during the US Eastern work day. Ping me any time on Twitter - I'm
@eraserhd  - or gchat.
Status

Our intention is for the unit tests to provide friendly documention of
what's been implemented so far. To run the unit tests with verbose output,
use

$ lein midje :print-facts

Installing

   - Works with Leiningen 2.3.4
   - On Linux, ncurses-dev or curses-dev or equivalent must be installed.

$ git clone https://github.com/maitria/avi.git
$ cd avi
$ lein install

On Linux, you'll likely not have access to /usr/local. In that case you'll
need to use sudo lein install instead.

To be specific, you're quoting the list in your def, so the a1 and a2 symbols 
are
not evaluated.

  user=> (defrecord Ape [fname lname])
  user.Ape
  user=> (def a1 (->Ape "test1" "test2"))
  #'user/a1
  user=> (def a2 (->Ape "test3" "test4"))
  #'user/a2

  user=> '(a1 a2)
  (a1 a2)
  user=> (quote (a1 a2))
  (a1 a2)
  user=> (list a1 a2)
  (#user.Ape{:fname "test1", :lname "test2"} #user.Ape{:fname "test3", :lname 
"test4"})

  user=> (def alist (list a1 a2))
  #'user/alist
  user=> (filter #(= "test1" (:fname %)) alist)
  (#user.Ape{:fname "test1", :lname "test2"})

  ;; Clojure idioms tend toward vectors and vector literals rather than
  ;; lists. If you have a background in Common Lisp or Scheme, this can
  ;; take some getting used to. One nice consequence is you don't have
  ;; to worry about quoting most of the time.
  user=> (filter #(= "test1" (:fname %)) [a1 a2])
  (#user.Ape{:fname "test1", :lname "test2"})

your list doesn't contain the records, your list contains the symbols 'a1

Re: [ANN] Clojure 1.7.0-alpha6 released

[Andy Fingerhut]

I believe that change is due to this commit from early March 2015:
https://github.com/clojure/clojure/commit/692645c73c86d12c93a97c858dc6e8b0f4280a0b

Nicola Mometto had opened a ticket CLJ-1593 for this issue:
http://dev.clojure.org/jira/browse/CLJ-1593
The commit did not reference the ticket, but Nicola noticed the commit and
closed the ticket due to that commit.

Alex, would it be appropriate to include a reference to CLJ-1593 in the
Clojure 1.7 release notes?

Newbie question about filtrering defrecord

[Magnus Javerberg]

Hi!

I'm new to clojure, and have problem understanding how to filter a list of 
defrecords. 
I have tried different variations on the following:

(defrecord Ape [fname lname])
(def a1 (->Ape "test1" "test2"))
(def a2 (->Ape "test3" "test4"))
(def alist '(a1 a2))

(filter #(= "test1" (:fname %)) alist)

I expect the filter to match the a2 record, but I obviously do something 
wrong and would appreciate any suggestion.

Kind regards
Magnus Jäverberg

Interesting.  My code was actually calling range with 2 args, as I want a 
1-based range.  The 1 was a literal, and to support the non-bigint case I 
don't want to hardwire it to 1N.  Now I see that:

(range 1N 5N) => (1N  2N 3N 4N)
(range 1 5N) => (1 2 3 4)

So I could pass (/ n n ) as my first arg to range and I'll get the desired 
type in all cases.

But this behavior of 'range' now feels quirky to me.

You could try (range (* 0 n) n). A little silly, but does avoid the
conditional.

You could consider also creating a JIRA issue asking for range to match the
type of its argument in the 1-arity case. No idea whether it would be
accepted, though.

I like your conditional better, so seeing that is welcome.

Regarding the last point, I understand that what you say is generally true, 
but in this specific case my function arg was defining the end of a 'range' 
call that was fed into other logic.

(range  5N) => (0 1 2 3 4)  ;  i.e. the "bigint-ness" is lost

So in this particular case I needed to "inject" bigint into the process 
later in some way.

Clojure 1.2 and earlier auto-promoted, if I recall correctly, but that has
not been the case since Clojure 1.3, released in Sep 2011.  You may have
found something published before then.

Clojure 1.3 and later do give a bigint result for integer arithmetic if any
of the arguments are bigints, e.g. (+ 1N 1) => 2N

More commonly I have seen (instance? clojure.lang.BigInt n) rather than (=
clojure.lang.BigInt (type n)), but I do not know any way to avoid the
conditional here.

I would ask that you consider whether you really do need this check,
though, since if your argument is BigInt and is combined with any
arithmetic operation with a local long value in the function, the result
will be BigInt.

How to coerce to bigint ?

[Paul Roush]

I have 2 questions related to bigints.

1) I've read things suggesting Clojure auto-converts between int, long, and 
bigint to prevent overflow.  That isn't the behavior I've experienced.  Did 
something change from an older release of Clojure to more recent ones?

2) I found myself wanting to write a function that would use bigint math vs 
not depending on whether I passed a bigint in as arg.  Internally I wanted 
to "seed" a reduce call with either 1 or 1N as appropriate.  So I wanted to 
write something like this (except I'd like it to work):

(defn foo [n]
  (cast (type n) 1))

; (foo 3) => 1
; (foo 42N) => 1N

The following works, but I'd like to understand if I can avoid the 
conditional:

(defn foo [n]
  (if (= clojure.lang.BigInt (type n)) 1N 1))

Re: [ANN] Clojure 1.7.0-alpha6 released

[Ian Rumford]

Hi Alex, All,

An observation really.

I've just noticed that a literal map e.g. (def m {:a 1 :b 2 :c 3}) in 
alpha6 is an array map not hash map.  

In 1.6.0 and 1.7.0-alpha5  its a hash map.

Couldn't find any obvious statement in the release notes but interested in 
the background to the change.

lein checkout dependencies with cljx project

[Colin Yates]

Hi,

I have a common library which I want to use in both Clojure and 
ClojureScript. The project uses cljx and works a treat and the generated 
clj and cljs are available to use alongside the hard coded clj and cljs. 

However, when I add that project (after doing the initial lein install) to 
the checkouts directory of another project, that other project cannot see 
the generated cljs.

I am not doing anything special in terms of packaging the generated cljs in 
the common project as I assumed the magic of lein checkouts and cljx would 
handle that for me.

Any suggestions?

Thanks!

Re: anybody here who use emacs to edit closure? is emacs lisp a good starting point to learn closure?

[Tj Gabbour]

Oh, and I'd try to figure out if this theory has any merit: do things like 
paredit and yasnippet help you intuitively think in terms of manipulating 
structure rather than text? Because in Clojure, you're constantly 
transforming and pushing around units of data.

[ANN] Baum - Extensible EDSL in EDN for configuration files

[Ryo Fukumuro]

Hi all,

I'd like to announce the release of Baum.

https://github.com/rkworks/baum

Baum, my first public library for Clojure, is designed to create
"self-contained" configuration files.

It allows you to include the following things in your configuration files:

 - References to external files
 - References to environment variables with a fallback value
 - Conditional loading of a part of config tree
 - `let`
 - etc

And it is very easy to extend the DSL to add new features.
For more details, please see README.

Any suggestions are welcome.

Best,
Ryo

Re: anybody here who use emacs to edit closure? is emacs lisp a good starting point to learn closure?

[Tj Gabbour]

Hi!

This highly depends on what’s most effective for you. If I were your tutor 
[1], I’d hear “but i wanna to start from emacs and emacs lisp,” and take 
that as a strong indicator that this path (first exploring Emacs) might be 
effective for you. 

Useful to probe more deeply into two threads: your interest in Emacs and 
interest in Clojure. Why you find these interesting. (For example, do you 
find Emacs a pleasant, customizable environment to live in?) 

A couple lessons which seem transferable are: a) getting used to 
parens/brackets as delimiting code/data units, and b) getting used to an 
environment you can interactively change while it runs. 

But I really don’t know. I've only written small Emacs Lisp programs. 
(Unlike say Bozhidar, who also responded.)

All the best, 
   Tj 

 [1] I tutor someone in computing, so that’s a common frame of reference. 
(But it’s limited since I haven’t tutored many. Like a tailor who knows 
only a few body types.)
