Re: Stumped: unable to resolve symbol in macro expansion

[Dave Tenny]

Doh!  Major face palm.  I had such a bad case of tunnel vision on the macro
definition I forgot to look up the stack once I'd fixed the macro.  Thanks.
 Good to have extra eyes.

 Hello,

 I am living in Poland and i have a little problem there... totally 0 
 jobs for Clojure Programmers.

 I am also beginner in Clojure. More about my IT skills you can read on 
 site http://wladyka.eu/ .

 Do you know any option to get a job in Europe or remotely if i don't 
 have any seriously experience with Clojure? But i see it's good and i want 
 use that more then others languages. I can start with less salary but in 
 my 
 area is big trouble to find any job with Clojure...

 If you know somebody who need fresh blood tell him about me :)

Just use clojure.jdbc or clojure.java.jdbc with a validation library 
(Validateur,
Schema, Bouncer,  etc).

There is no rush to use the newest hotness in the Clojure community so Korma
should work OK if that's what you want.

I liked the no-fuss integration of relationships for the particular project

Re: Is Korma still a good current choice for DB backend?

[Timothy Baldridge]

Also, read the rationale behint yesql: https://github.com/krisajenkins/yesql
IMO, it hits the nail on the head. ORMs are both crappy object systems and
crappy DB DSLs. With a library like yesql you write your queries in pure
SQL and get pure data back. Now you can fully leverage both SQL and
Clojure.

create vectors for each key/value pair

[emptya45]

Hi, 

I have an unsorted map:

(def my-map 
{1405961887 20, 
 1405960895 20, 
 1405961919 20, 
 1405960927 20, 
 1405960959 21,
 1405960991 20, 
 1405961023 20, 
 1405961055 18,
 1405961087 23, 
 1405961119 17, 
 1405961151 23, 
 1405961183 19,
 1405961215 20}

I'd like to be able to sort the map by key and then place each value pair 
into a vector. 

An attempt at (sorted-map my-map) returns 'No value supplied for key: 
{1405961887 20 ' }

When I attempt to create a vector from the key/pairs 

(map #(vector %) my-map)

I receive each key/value in a vector within a vector

([[1405961887 20]]
 [[1405960895 20]]
 [[1405961919 20]]
 [[1405960927 20]]
 [[1405960959 21]]
 [[1405960991 20]]
 [[1405961023 20]]
 [[1405961055 18]]
 [[1405961087 23]]
 [[1405961119 17]]
 [[1405961151 23]]
 [[1405961183 19]]
 [[1405961215 20]])

My goal is to create a collection of vectors to place in an Incanter 
dataset:

incanter/dataset ["time" "requests"]
   [[1405961887 20]
[1405960895 20]
[[1405961919 20]])

Many Thanks

Adrian

Re: create vectors for each key/value pair

[Marc Limotte]

I think you just want:

user=> (sort my-map)
([1405960895 20] [1405960927 20] [1405960959 21] [1405960991 20]
[1405961023 20] [1405961055 18] [1405961087 23] [1405961119 17] [1405961151
23] [1405961183 19] [1405961215 20] [1405961887 20] [1405961919 20])

sort will call seq on it's argument.  The seq from a Map is a sequence of
vectors ([k v], ...).  The default sorting for the vectors will be the
natural sort of the first element, then the second element, and so on.

You can also do (-> my-map sort reverse) if you want a DESC sort.

Re: create vectors for each key/value pair

[Alex Walker]

First, the fn sorted-map 
 is 
variable argument and expects to be given (sorted-map :z 1, :b 2, :a 3) and 
not (sorted-map my-map).

To use sorted-map, you'll need to do something like: (apply sorted-map 
(mapcat identity my-map))

Second, when a clojure hash-map is used as a sequence, each key/value pair 
is actually a MapEntry, which behaves like a vector of [key value].  So 
your map fn is effectively doing (vector [1405961887 20]), which produces a 
doubly-wrapped [[1405961887 20]] for each respective element.

clojure 1.6 eval from Java

[Dan Campbell]

Hi,

I'm confused about the new api, with reference to using eval, from a 
non-clojure jvm app.

Are we still supposed to invoke eval from RT.var?  That's working fine for 
me, so far.


The new clojure.java.api seems to be relevant only to calling individual 
functions.  My current app just needs to evaluate clojure expressions in 
general, the '( function & parms )' that you would type in a repl.


A related question would be, can we use the new api, to evaluate clojure 
expressions?

Clojure XML - is there a better way?

[Adrian O'Sullivan]

Hi! 

I struggled to use clojure.data.zip.xml in the absence of a root node.  My 
XML looks like this:



http://pmd.sourceforge.net/pmd-5.1.2/rules/java/codesize.html#TooManyMethods";
 
priority="3">
This class has too many methods, consider refactoring it.



http://pmd.sourceforge.net/pmd-5.1.2/rules/java/codesize.html#TooManyMethods";
 
priority="3">
This class has too many methods, consider refactoring it.

http://pmd.sourceforge.net/pmd-5.1.2/rules/java/codesize.html#ExcessiveMethodLength";
 
priority="3">
Avoid really long methods.



... more ...

I want to extract ExcessiveMethodLength violations, and then calculate the 
difference between the beginline and endline attributes.  Here's what I 
came up with:

(for [x pmd-seq :when (and 
(= :violation (:tag x)) 
(= "ExcessiveMethodLength" (:rule (:attrs x))) )]  
   (- (read-string (:endline (:attrs x))) (read-string (:beginline (:attrs 
x)))  ))


It does the job, but I feel that zip xml would have been better, but I 
could not figure out how to filter the data.

Any insights appreciated.

Thanks
Adrian

Re: Clojure XML - is there a better way?

[Mike Fikes]

My only gut reaction is that, without a root node, it doesn't seem that you 
have "XML". (It is certainly not a well formed document, and I would 
suspect lots of XML tools/libraries would have difficulty coping with the 
example you provided.)

timbre logging, java libs

[Brian Craft]

Is there any good way to use timbre in a project with java libs, e.g. c3p0, 
that use java logging APIs? Java logging is such a hopeless muddle I don't 
pretend to understand it, but my impression is that libs like c3p0 use 
assorted backends (log4j, etc.), which in turn use assorted "appenders" to 
write to files, dbs, etc. clojure.tools.logging uses the same backends 
(log4j, etc.), to the same purpose. Timbre, however, just implements 
appenders, so it can't forward to log4j, and log4j can't forward to timbre. 
Timbre can operate as a backend for clojure.tools.logging, but that only 
helps with clojure libs.

Is any of this correct?

Looking for Clojure-centric career advice/suggestions

[VaedaStrike]

TL;DR - Got as close to a dream job as I could have wanted, after 6 months 
lost it. Now, with only experience in Clojure and Scala, and seemingly 
stuck in Utah, not sure what's the best next course of action.

I'm putting this out there because of all the good experiences I've had 
over the years with people in the Clojure community. I very much value what 
you all have done and do. As best I can tell you're the salt of the earth.

I'm a rather newly minted programmer. Six months on the job.

I claim Clojure as my first language simply because I never saw my initial 
tryst with VB.NET and Visual Studio as being much more than tinkering/not 
really understanding. 

It's kind of a long and convoluted story as to how I got here, I can share 
it if anyone's interested, but for now let's just say that my 6 years of 
trying to learn Clojure in my spare time landed me my first official 
programming gig ... learning Scala.

Being a bit tied to Utah (fiscally and family-wise at the moment) this 
seemed to be the best chance I had at starting my professional programming 
career on as close to my terms as possible, so I took it.

I still like Clojure better than Scala (though I've learned a lot using 
Scala), but these last six months programming in a professional environment 
has cemented for me that I absolutely love programming. Being able to work 
in a code repository of functional, industry oriented code and doing real 
stuff that made a difference, I'll just say I never thought work could be 
so enjoyable, nor that I'd ever have the chance to work with so many smart 
and good people. 

Unfortunately, as an outgrowth of my newness, company politics and a change 
in team management I was told to look for a job elsewhere. 

I got right to work and applied to everything that looked anything close to 
what I then had. 

I was amazed, the first four I applied to all responded well. And as a plus 
they all were either using, or experimenting with either Clojure or Scala.

Unfortunately, as unexpected as the job loss was for myself, it hit my wife 
even harder, we've not had an easy time our first 4 years of marriage on 
the economic side of things and emotionally she was rather paralyzed by 
this news. This combined in an unfortunate way with the fact that all four 
places quickly responded to me and, also in a difficult way, with a few 
decisions in how to approach the coding challenges I was given. In short, I 
was not terribly impressive for any of the four companies. Ironically the 
one company where I felt I did the worst has been the most understanding 
and is willing to give me a second chance after I take a couple of 
challenges they've given me.

The problem I'm looking for help with is to know how to approach this in 
the best way that keeps me bringing in food for and keeping a roof over 
 the head of my wife and son, all this hopefully without sidelining my 
career goals, to the extent that that's possible. 

While I can't go and do a hard ruling out of anything, the whole relocation 
idea to where jobs are would be an insanely tough sell. I'm not sure if 
anyone would take on a remote worker as green as myself. And here, where 
I'm at in Utah, is hardly full of companies ready to take some guy who has 
6 months of Scala experience and only self-taught (and what most would 
consider 'hobby' experience) with Clojure. Aside from the fact that very 
few even know what those languages are is the fact that since I've been so 
focused on functional programming I'm really hard pressed to show people 
what I know and what I can do. And then finding someone willing to take a 
chance on me.

I'd like to avoid the tech support jobs I've had before as they would both 
pay substantially less AND they would be significant distractions on the 
time for me to move forward and learn. I just feel like I'm on the cusp of 
being a very productive and capable programmer and, at the same time, like 
it's all trying to get away from me. I'm trying to learn and apply what I 
know in the time between applying for work and handling all the other 
miscellany connected with that and keeping my little family going. And 
while I can't rule out school I'm having a hard time justifying it in my 
mind when I feel like I'm so close to being a very capable programmer.

I've really studied a great deal on a significant number of things, 
everything from Relational database theory to things like REST and HATEOAS 
as well as having used a little of Instaparse a previous job (one of the 
big helps in getting the Scala job). Most recently I've been dabbling in Om 
and Pedestal in my own time, I've also gotten my hands wet with a bit of 
CSS & SASS. And, while not entirely connected to coding, I grew up around 
Illustrator and Photoshop and am very conversant in Graphic Design (but 
most of my experience is for printed mediums).

Any advice or suggestions?

Re: How to control evaluation of code with cider

[Timothy Washington]

Ooh, this looks interesting. Afraid I don't know enough elisp to be useful.
But it looks like you're already prompting the caller for the
*channel-repl/cider-function* name. Is there a reason you're not using it (
*prefix*) ?

Also can I ask how / where you plan to use this? Or is it just a generic
piece of code that will fit into a processing pipeline.

Is this something you would integrate with piggieback
 or austin
?

Re: Is Korma still a good current choice for DB backend?

[Sean Corfield]

I'm curious as to how folks using Yesql deal with conditional queries - which 
is something we seem to run into a lot.

For example, we have some business logic that might optionally be passed a date 
range and maybe some other qualifier so our query would be:

(str "SELECT ... main query stuff WHERE basic conditions"
(when date-range (str " AND dateUpdated >= ? AND dateUpdated < 
?"))
(when qualifier " AND someColumn = ?"))

and then some conditions to build the parameters:

(cond-> basic-params
date-range (concat date-range)
qualifier (concat [qualifier]))

It seems like with Yesql we'd have to have four different query functions and 
then code like this:

(if date-range
(if qualifier
(query-with-date-range-and-qualifier db basic params 
(first date-range) (second date-range) qualifier)
(query-with-date-range db basic params (first 
date-range) (second date-range)))
(if qualifier
(query-with-qualifier db basic params qualifier)
(query-basic db basic params)))

Re: Looking for Clojure-centric career advice/suggestions

[Zach Oakes]

It sounds like you know what you want, and you're fortunate for that. I 
often don't, and I can tell you that greatly complicates things. At any 
rate, there are few things more stressful than career changes.

Perhaps you are casting too small a net. Many here would love to be paid to 
write Clojure, but if you can't find such an opportunity, you may want to 
broaden your search for functional or JVM-based jobs instead.

It is also very helpful to have some open source work you can show off. 
Coding challenges are often completely detached from reality, and open 
source work can sometimes offset their importance.
