Re: clojure-refactoring - what's the best way to distribute a clojure + emacs/elisp combined package?

[Joost]

I've implemented Phil's suggestion of using swank_elisp_payloads, and
version 0.6.3 of clojure-refactoring is available right now as a
leiningen plugin:

lein plugin install joodie/clojure-refactoring 0.6.3

The clojure-refactoring Emacs functions will then be available under C-
c C-f whenever you run clojure-jack-in to start a SLIME session.

For more info, see the readme at https://github.com/joodie/clojure-refactoring

Thanks!
Joost.

Re: Introspecting functions

[Stathis Sideris]

Although it doesn't directly answer your question, I have used (with-
meta) to attach debug information to generated functions in the past.
If you are writing function combinators you can even do this
recursively by taking the existing debug info from a function that you
generated before and combine it new debug info for the function you
are currently generating.

For an actual example on how to do this, see (and-matcher) and the
surrounding matcher functions here:

https://github.com/stathissideris/clarity/blob/master/src/clarity/structure.clj

Re: Which autodoc dep for clojure 1.3 (and advice on how to solve such questions generally)

[Hubert Iwaniuk]

Hi Phil,

With "Leiningen 1.6.1.1 on Java 1.6.0_26 Java HotSpot(TM) 64-Bit Server VM" 
executing:
$ lein plugin install audodoc 0.7.1
fails advising to download artifact by hand.
Though searching for it:
$ lein search "autodoc AND NOT g:org.clojars*"
Shows line with:
[autodoc "0.7.1"] A tool to build HTML documentation from your Clojure source

Could it be that somehow metadata is not in sync with content of repository?

Currently I'm not able to get autodoc running at all :(

Cheers,
Hubert.

Things like autodoc are usually best installed as user-level plugins,
so stick with "lein plugin install $FOO $VERSION". To find the right
version, usually your best bet is something like:

 $ lein search "autodoc AND NOT g:org.clojars*"


So, I'm asking for a suggested dep for that, but also I am wondering
what is the standard operating procedure for resolving such dependency
issues.  Is there some Maven black magick I should familiarize myself
with in order to list packages and their deps?


If you're interested in a full transitive dependency listing, you
actually need Maven:

 $ lein pom&&  mvn dependency:tree

I hope to port that to lein at some point as it's fantastically useful.

conditional get with feedparser-clj (or another RSS feed parser)?

[George Oliver]

hi,

I'm making a site similar to clojurls.com (a more dynamic version of
my old site ifurls.tumblr.com), so I'm working with feedparser-clj
[1].

It doesn't look like feedparser currently wraps the conditional get
from RomeFetcher [2], so I'm wondering if there is a Clojure library
that does provide something similar, or what the best course might be
-- wrap it myself, use RomeFetcher directly, or use something else.

I'm new to Clojure and Java so I'd like some advice beforehand.

thanks, George

Adding forms to fn

[N8Dawgrr]

Hi Clojure Group,

I'm new to the group, apologies if this topic has been raised before.
Basically I'm wondering if there is a reason why the form used to
defined a function isn't attached as meta-data to the function.
Clojure is a isomorphic language and this capability would really help
me out with some libraries I'm building.

Clojure forms are pretty compact, much smaller than the compiled byte-
code, I can't see it having a big impact on the memory footprint.

People might argue that I could provide a local fn macro which
captures the form meta-data and calls the clojure.core/fn macro to do
the real work. The problem with this approach is that the reader macro
#(%) expands to fn*. There is no way of overriding the fn* symbol.

What are peoples thoughts?

Re: Simple Made Easy - Any Examples?

[Gary Trakhman]

I think it's probably harder to actually show 'best practice' in a lisp 
than say a language like java.  The notion of a design pattern can always 
be abstracted away with functions or macros.  So, the examples I've seen so 
far are very small scale, eg: use lazy seqs and function composition 
instead of loop/recur, that kind of thing.

I've only looked at the code for ~5 minutes, but I think I might understand 
what's going on.  To confirm: clojure-refactoring is sending something like 
diffs back to the refactoring-mode/SLIME, and that mode/emacs is what is 
actually performing the modifications to affected files?

Thanks,

- Chas

Hello,

As far as I remember, clojure-refactoring considered (or is using ?)
using parsley + the clojure grammar in paredit.clj for some (all ?) of
its refactorings.

What is the current status of this ? (I also have a long delayed todo
list note on adding refactoring to CCW, for sure ! :-) )

Korma - cannot acquire connections

[AndyK]

I believe I have setup korma correctly with
(require '[korma.db :as db])
(require '[korma.core :as sql])
(db/defdb devdb (db/mysql {:db "mydb" :host "localhost" :user
"me" :password "mypass"}))
(sql/defentity mytable
(sql/select mytable (sql/fields :id) (sql/where {:id 1})))

But I'm getting
SQLException:
 Message: Connections could not be acquired from the underlying
database!
 SQLState: null
 Error Code: 0

(db/get-connection devdb) returns a clojure.lang.PersistentHashMap -
is that right? or should it be the underlying java.sql.Connection?

I have the mysql driver in my classpath, am able to Class/forName the
driver, create a connection, and query on the connection - all
manually. Korma looks pretty cool and I'd like to be using, any ideas?

Update swank classpath on the fly?

[AndyK]

I've noticed that swank (which I run in emacs using M-x clojure-jack-
in) doesn't pickup changes to the classpath on-the-fly. For example,
if I update my leiningen project.clj with a new dependency and run
lein deps, I need to restart swank to have it use the library. Is
there a way to load something into a running swank without restarting
it (which causes loss of state in the slime-repl).

I'd settle for a fast way to restart the session.

a better way to write this

[Dennis Haupt]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

here's a part of my clojureoids-code:

  (let [type-pred #()
bounds-check #()
contact #()
full-test (fn [element] (and (type-pred element) (bounds-check
element) (contact element)))]
  (filter full-test (:game-elements @world-atom))

is there a way to write the full-test in a way that doesn't force me
to repeat the "function " pattern inside the and?

Re: a better way to write this

[Timothy Baldridge]

Using collections:

(every? true? (map #(%1 %2) [func1 func2] (repeat common-argument)))

where func1 func2 are your functions. and common-argument is the
argument shared by them all.

Or something like this:

(every? true? (map #(%1 %2) [type-pred bounds-check contact] (repeat element)))

Granted this won't be the fastest method in the world (macros would
probably be better), as there's going to be a fair amount of object
creation going on, and now instead of invoking 3 functions, we're
invoking much more. But at least this code is readable, and fairly
easy to understand.

This is part of what pomegranate provides:

https://github.com/cemerick/pomegranate

It won't pick up changes from your project.clj, but it does provide an 
`add-dependencies` function that works with leiningen-style dependency notation 
(and an improved `add-classpath` if you just have jars available on disk you 
want to dynamically add to your classpath).

However, I have at least one report that pomegranate fails under swank:

https://github.com/cemerick/pomegranate/issues/1

It'd be great to get confirmation or not of that issue (or, even better, a 
patch to make it work under swank!).  FWIW, it works fine in a command-line 
REPL and with nREPL (jark, counterclockwise).  I've yet to test it with 
swank/slime myself.

Cheers,

- Chas

Re: a better way to write this

You could try using "every-pred" to combine your predicates, which I
think would be equivalent:

(let [full-test (every-pred type-pred bounds-check contact)]
   ...

Re: Korma - cannot acquire connections

Did you mean to define the select within the defentity?

(sql/defentity mytable    (sql/select mytable (sql/fields :id) (sql/

I does this work?

(sql/defentity mytable
  (:pk <<< YOUR PRIMARY KEY AS A KEYWORD>>>)
  (table <<>>)
 (database devdb))

(sql/select mytable (sql/fields :id) (sql/where {:id 1}))

Actually it should read:

  (sql/table <<>>)
  (sql/database devdb))

(sql/select mytable (sql/fields :id) (sql/where {:id 1}))

Re: Simple Made Easy - Any Examples?

For me personally the main areas that Rich cited that I've not found
good examples for are Rules, Set Functions, and Queues.
In particular moving the rules out sounds like a great idea.

I'll have a look at the projects that David suggested.

see if any branch of a cond succeeded

[Martin DeMello]

What's the cleanest way to run a piece of code if any branch of a cond
statement succeeded, without relying on the return value of the
individual clauses not to be nil?

For example, if I have the following piece of code that says I can
only move left or up

(cond
  (= dir :left) (move-left)
  (= dir :up)  (move-up))

but (move-left) or (move-up) could themselves return nil, is there any
nice way to check if one of them was called?

What about something like this -

(cond
 (= dir :left) (move-left)
 (= dir :up)  (move-up)
 :else :nok)

Or

(cond
 (= dir :left) [(move-left)]
 (= dir :up)  [(move-up)])
