Hi,
I'm happy to release version 0.7.0 of the Promenade library. This release
switches expression sequencing to use clojure.core/reduce, hence adding

Hi,
Promenade is a Clojure/ClojureScript library to elegantly handle errors and
other oddities. The 0.6.0 release adds support for (1) wrapping functions

If you enabled Log4j console logger, the logs should appear in the REPL too.
See example at

You do not necessarily need log4j to log to the REPL via

Logging calls are far too frequent to practically pass config as argument
everywhere, hence some kind of shared implicit context is required. Which
logging libraries are you dealing with? If you use Timbre[1], you can pass
config using dynamic vars or altering global state. If you use Logback[2]
I think what you need on the http-kit side is a context "stripper"

You should probably include the right dependencies in project.clj, e.g.

I have seen (and I keep seeing) a ton of Java code that performs poorly.
Empirically, it's equally easy to write a slow Java app. You always need a
discerning programmer to get good performance from any language/tool.
Numbers like 1/4 or 1/10 can be better discussed in presence of the
use-cases

ORMs are not prevalent in Clojure. You can use java.jdbc (the 0.3.x series
or later) with one of the SQL generators (HoneySQL, YeSQL etc) that you
like. See what works for y
Can you post the SQL template (with ? symbols) you are trying to execute?
Usually, with PostgreSQL you can specify ?::integer in place of ? to imply
that the passed parameter is an integer.

Hi,
I'm happy to announce clj-liquibase version
0.5.1: https://github.com/kumarshantanu/clj-liquibase for database (JDBC)
change management.
Since 0.4.0, this version upgraded Liquibase dependency from 2.5 to 3.0 and
added support for free-form SQL and SQL files as units of change. (Thanks

Hi Jan,
This not directly related, but i thought it might be useful in some way. In
case you do the java interop stuff on your own to implement the servlet 3.0
methods, you might want to use lein-servlet to run the servlet using Jetty
9 maybe.

If you are only going to read the CSV files, you can put the CSV file in
`resources` directory (so that it is part of the jar/uberjar), and use
https://github.com/clojure/data.csv with
http://clojuredocs.org/clojure_core/clojure.java.io/resource to read the
data. If you need to make some change
Author of lein-localrepo here. Just to mention few points:
1. Leiningen builds over Maven's transitive dependency management system.
So, I guess at some point of time you just have to accept Maven's
nomenclature.
2. `lein install` works when you have source code and a `project.clj` for
your pr
