How to exclude compile-time dependencies from uberjar?
I'm trying to get the smallest uberjar as possible. Currently I have a bunch of dependencies for compiling server resources (clojurescript, garden...) that are required at compile-time, but don't have to be in the uberjar. How can I create an uberjar without bundling these resources? Thanks! -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: [ANN] bidi 1.20.0 - with Schema suppport
Hi Dylan, Yes, that's right. This is validation for the bidi route structure itself. For now, I've left it open to the bidi user whether and when to use route validation (although I may add it to modular in due course as you point out) Libraries that use ring-swagger, https://github.com/metosin/ring-swagger, including yada, provide path parameter validation. Therefore I don't think it's necessary to add path parameter validation to bidi. Regards, Malcolm On Tuesday, 30 June 2015 04:50:06 UTC+1, Dylan Butman wrote: Hey Malcolm, Just confirming my understand, the schema addition is to validate the bidi routes themselves, not path parameters matched within the routes, right? Is this something you're thinking one might do at component start, say https://github.com/juxt/modular/blob/master/modules/bidi/src/modular/bidi.clj#L88 .

Until now, there has been no way to validate whether that data conforms to the expected structure. Not doing so can often lead to problems. I've just released a new version that defines a Prismatic Schema for letting you check and validate your bidi routes in your code. Schema validation works for both Clojure and ClojureScript, now that ClojureScript has Var instances (see https://groups.google.com/forum/#!topic/prismatic-plumbing/jqOkv_r8QZk) See http://github.com/juxt/bidi for further details. -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Clojars Private/Commercial Repos
The past few teams I've been on have used variously S3, Nexus, and Artifactory, and I wasn't especially happy with any of them. I think there is a sweet spot of usability (for small/medium teams) and technical capability that hasn't really been achieved by anything available. Of what's available today, Artifactory's SaaS (Cloud version) looks most palatable but I haven't used it enough to recommend it. To hit the sweet spot for myself, and for others with similar tastes, I've been working with Micha Niskin on a commercial product called Projars that maybe be of interest: http://projars.com/. Incidentally, the previous owner of the projars.com domain had a different and interesting idea for it, as a kind of marketplace for commercial libraries: https://web.archive.org/web/20140309074426/http://projars.com/ Maybe this could still be a thing? I am very grateful to Alex Osborne's stewardship of Clojars and the efforts of all its contributors over the years. It is an important community asset. If finances ever became a problem, I would be happy to contribute, as I'm sure many others in the community would also.

Doing that has been considered in the past, but isn't something I'm comfortable doing right now, due to other obligations. The hosting costs are relatively small, and still being sponsored by Alex Osborne (clojars' original author). I've considered selling corporate sponsorships or having a fundraising campaign to establish a fund that could take that burden off of Alex, and to have on hand to cover contracting someone to help with recovering from potential compromises (like the linode breach[1]), patching vulnerabilities (heartbleed, etc), or rebuilding the server in case of failure, if such help is needed. I have no idea if I'll need some sort of legal entity to hold that money, but if one is needed, that might be something the recently proposed Clojure community organization[2] could handle.

[ANN] Clojure 1.7.0 is now available
We are pleased to announce the release of Clojure 1.7. - Download: https://repo1.maven.org/maven2/org/clojure/clojure/1.7.0/ - Leiningen: [org.clojure/clojure 1.7.0] The two headline features for 1.7 are transducers and reader conditionals. Also see the complete list ( https://github.com/clojure/clojure/blob/master/changes.md) of all changes since Clojure 1.6 for more details. ## Transducers Transducers (http://clojure.org/transducers) are composable algorithmic transformations. They are independent from the context of their input and output sources and specify only the essence of the transformation in terms of an individual element. Because transducers are decoupled from input or output sources, they can be used in many different processes - collections, streams, channels, observables, etc. Transducers compose directly, without awareness of input or creation of intermediate aggregates. Many existing sequence functions now have a new arity (one fewer argument than before). This arity will return a transducer that represents the same logic but is independent of lazy sequence processing. Functions included are: map, mapcat, filter, remove, take, take-while, drop, drop-while, take-nth, replace, partition-by, partition-all, keep, keep-indexed, map-indexed, distinct, and interpose. Additionally some new transducer functions have been added: cat, dedupe, and random-sample. Transducers can be used in several new or existing contexts: * into - to collect the results of applying a transducer * sequence - to incrementally compute the result of a transducer * transduce - to immediately compute the result of a transducer * eduction - to delay computation and recompute each time * core.async - to apply a transducer while values traverse a channel ## Portable Clojure and Reader Conditionals It is now common to see a library or application targeting multiple Clojure platforms with a single codebase. Clojure 1.7 introduces a new extension (.cljc) for files that can be loaded by Clojure and ClojureScript (and other Clojure platforms). There will often be some parts of the code that vary between platforms. The primary mechanism for dealing with platform-specific code is to isolate that code into a minimal set of namespaces and then provide platform-specific versions (.clj/.class or .cljs) of those namespaces. To support cases where is not feasible to isolate the varying parts of the code, or where the code is mostly portable with only small platform-specific parts, 1.7 provides Reader Conditionals ( http://clojure.org/reader#The%20Reader--Reader%20Conditionals). Reader conditionals are a new reader form that is only allowed in portable cljc files. A reader conditional expression is similar to a cond in that it specifies alternating platform identifiers and expressions.

Re: [ANN] Introducing Yagni, a Leiningen plugin for finding unused code
Nice. It would be really cool if run-yagni was a pure function of source-paths and mains. This would make the dependency on lein optional and allow adoption on e.g. mainland Java projects.

We are pleased to announce the release of Clojure 1.7.
- Download: https://repo1.maven.org/maven2/org/clojure/clojure/1.7.0/
- Leiningen: [org.clojure/clojure 1.7.0]
The two headline features for 1.7 are transducers and reader
conditionals. Also see the complete list (
https://github.com/clojure/clojure/blob/master/changes.md) of all
changes since Clojure 1.6 for more details.
## Transducers
Transducers (http://clojure.org/transducers) are composable algorithmic
transformations. They are independent from the context of their input and
output sources and specify only the essence of the transformation in terms
of an individual element. Because transducers are decoupled from input or
output sources, they can be used in many different processes - collections,
streams, channels, observables, etc. Transducers compose directly, without
awareness of input or creation of intermediate aggregates.
Many existing sequence functions now have a new arity (one fewer argument
than before). This arity will return a transducer that represents the same
logic but is independent of lazy sequence processing. Functions included
are: map, mapcat, filter, remove, take, take-while, drop, drop-while,
take-nth, replace, partition-by, partition-all, keep, keep-indexed,
map-indexed, distinct, and interpose. Additionally some new transducer
functions have been added: cat, dedupe, and random-sample.
Transducers can be used in several new or existing contexts:
* into - to collect the results of applying a transducer
* sequence - to incrementally compute the result of a transducer
* transduce - to immediately compute the result of a transducer
* eduction - to delay computation and recompute each time
* core.async - to apply a transducer while values traverse a channel
## Portable Clojure and Reader Conditionals
It is now common to see a library or application targeting multiple
Clojure platforms with a single codebase. Clojure 1.7 introduces a new
extension (.cljc) for files that can be loaded by Clojure and ClojureScript
(and other Clojure platforms).
There will often be some parts of the code that vary between platforms.
The primary mechanism for dealing with platform-specific code is to isolate
that code into a minimal set of namespaces and then provide
platform-specific versions (.clj/.class or .cljs) of those namespaces.
To support cases where is not feasible to isolate the varying parts of
the code, or where the code is mostly portable with only small
platform-specific parts, 1.7 provides Reader Conditionals (
http://clojure.org/reader#The%20Reader--Reader%20Conditionals).
Reader conditionals are a new reader form that is only allowed in
portable cljc files. A reader conditional expression is similar to a cond
in that it specifies alternating platform identifiers and expressions. Each
platform is checked in turn until a match is found and the expression is
read. All expressions not selected are read but skipped. A final :default
fallthrough can be provided. If no expressions are matched, the reader
conditional will read nothing. The reader conditional splicing form takes a
sequential expression and splices the result into the surrounding code.

Re: Transducers/Eduction problem
The example is wrong. There are now two flavors of support for reduce through interfaces, IReduce and IReduceInit. The first one allows you to call reduce without an initial value. Eduction doesn't support that interface, but only IReduceInit. Reduce without an initial value is now discouraged.

Re: Clojars Private/Commercial Repos
+1. Neither S3 or Archiva have worked out well for us long term.

For many people, the thought of setting up and maintaining Nexus or Archiva isn't an appealing one. I'm aware of the S3 wagon, and perhaps that's what people use if they don't want Nexus. I'd be interested to hear what other people are doing, and whether Clojars would be a good middle ground between simplicity and functionality. Many Clojure users already have Clojars accounts and will have setup Lein to deploy here already. Additionally, many people would support Clojars for the goodwill factor. On the other hand I'm aware this would require more development effort, there may not be much demand for this, and the infrastructure costs may not be large enough that it's worth going down this route.

Re: Confusion about cljs.build.api/build
Update: thanks to a comment at the bottom of one of the files in the
clojurescript project
https://github.com/clojure/clojurescript/blob/master/src/main/clojure/cljs/closure.clj#L1828,
I think I know how to fix this. Instead of a list, I should have used a
vector. I don't know why this works, I imagine there is a seq? somewhere it
shouldn't be but I really don't know.

Hello,
I'm trying to use cljs.build.api/build to compile dynamically generated

case I've found is the following:
(cljs.build.api/build '((ns test.test)) {:optimizations :advanced})
The above prints a parse error from closure I think and then returns a
string that contains generic javascript about Math but nothing else:
ERROR: JSC_PARSE_ERROR. Parse error. primary expression expected at
test.test line 3 : 1
Are there other options I am supposed to be passing in? Do I have the
nesting wrong on the structures? I've tried a list like '(+ 1 1) instead
but the string output doesn't look to be doing any work and that level of
nesting doesn't seem to be what is implied by cljs.closurei/compile-for-seq
with it's forms argument. Any what is going on?

Re: Joda Time version conflict? Initializing JollyDayHoliday for SUTime
Also, your last error (about in-ns) is from an incompatible version of clj-time, not joda-time. By the way, this has nothing to do with interop, it's straight dependency management on the jvm. Concerning FD's solution of classloaders, you'll also jave to figure out a way to package the different versions into your JAR, which will not be trivial if both versions use the same package names (which seem to be the case). I think your best bet at this point is to carefully read the lein deps :tree output to note all of the required versions of clj-time and jodatime, and then try to play with either excludes or version ponning in your project.clj until you find a combination that works. Also remember that your code is the most flexible: are you absolutely stuck using clj-time 0.6.0 for your own code ?

The suggestion is to add the exclusions to your Ring dependency: [ring 1.4.0-RC1 :exclusions [clj-time joda-time]] See if that helps.

Your own direct dependencies will override transitive ones. Otherwise, as far as I can tell, you're stuck. Maybe you can try using an older clj-time? In theory, JodaTime 2.6 should not have any API-breaking changes since 2.1, or they should have called it 3.something. So, if you can force the NLP module to use JodaTime 2.6 it *should* work. If that fails, it may still be possible if you can force the two versions of JodaTime to load in separate classloaders. I haven't the foggiest how that might actually be achieved. Actually I'm somewhat surprised that the Java NLP component and clj-time are not *already* loading in different classloaders, the former in the standard Java classloader and the latter in Clojure's DynamicClassLoader. Two different versions of the same Java package or Clojure namespace can *usually* coexist peacefully in different classloaders, though, modulo native dependencies or centralized filesystem stuff (e.g. a single .foo file in the user directory that they both modify, stepping on each others' toes, and they can't be overridden to look for separate files to each keep their own version). If the worst comes to the worst, you may need to run the NLP module and the Clojure code in separate JVMs using some form of IPC to exchange data. Then deployment, startup, and shutdown become more complicated and annoying, and communication across the divide much less efficient (like kernel mode switching, IPC means carting data across address space boundaries), so ideally there'd be a clean internal boundary between the NLP-parts and the rest that has relatively little traffic crossing it. You'd then end up with a kind of NLP daemon and an application that had a dependency on it. -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Clojars Private/Commercial Repos
Clojars is pretty much a one man show right now, but it currently requires little time to maintain, and works fairly well. If it supported private repos, the maintenance and support time would go up considerably, and it would require some sort of business entity around it. Doing that has been considered in the past, but isn't something I'm comfortable doing right now, due to other obligations. The hosting costs are relatively small, and still being sponsored by Alex Osborne (clojars' original author). I've considered selling corporate sponsorships or having a fundraising campaign to establish a fund that could take that burden off of Alex, and to have on hand to cover contracting someone to help with recovering from potential compromises (like the linode breach[1]), patching vulnerabilities (heartbleed, etc), or rebuilding the server in case of failure, if such help is needed. I have no idea if I'll need some sort of legal entity to hold that money, but if one is needed, that might be something the recently proposed Clojure community organization[2] could handle. I know that it's often easier to give money over time, but if folks are interested in helping clojars now, we have quite a few open issues[3] that are ready for discussion/patches. - Toby [1]: https://groups.google.com/forum/#!topic/clojars-maintainers/uAVJVwRAnSU [2]: https://groups.google.com/d/msg/clojure/i2YqnCkeemM/0nOJaK8U91EJ [3]: https://groups.google.com/d/msg/clojars-maintainers/AKLPSVY5Qcw/w63eLy7pU58J On Tue, Jun 30, 2015 at 3:34 PM, Christopher Small metasoar...@gmail.com wrote: This is being done now with npm: https://www.npmjs.com/.

Re: [ClojureScript] [ANN] Clojure 1.7.0-beta3
Is anyone interested in filing a bug against IBM JDK 1.8.0 where it appears that its JIT compiler fails about half of the time when doing 'mvn clean test' in a Clojure 1.7.0 source tree? You can find some attachments in an earlier message of this thread that can get you started, but producing your own error logs with specific versions of OS, JDK, and Clojure source code would probably be best. Let me know if you can't reproduce it for some reason. I don't use IBM JDK very much, other than to see if anything goes wrong when you try to build and test Clojure using it. I'm hoping someone more motivated in seeing this fixed for the IBM JDK will take up the torch.
