Re: ClojureScript integration with Emacs/Cider ?
On Mon, Jan 6, 2014 at 11:10 PM, Colin Fleming colin.mailingl...@gmail.comwrote: Since Cursive (http://cursiveclojure.com) resolves everything statically from source, ClojureScript completion and navigation works for most symbols. There are still a lot that it doesn't know about since cljs-specific functionality is still pretty low, so js/* symbols have no support, and any functions included from Closure are not found either. But for pure cljs it should work pretty well. There are quite a few people using Cursive for cljs dev now, despite the slightly embarrassing lack of explicit support :-) Hi Colin, I just installed Cursive and looks very promising. I'll try using it. Do you plan to explicitly support ClojureScript? Do you have an ETA? That would be awesome, because viewing the implementation of Clojure's core libs is very valuable and from what I understand, there are differences between Clojure and ClojureScript (e.g. protocols are at the bottom in ClojureScript) and it would be valuable if I could click on a function and see its ClojureScript specific code and documentation. Also handling the Javascript interop would be awesome too.

Walking the classpath including the contents of jar files would be a way to construct such a list of USE-able (or REQUIRE-able) namespaces.

Are all clojure namespaces loaded in repl by default?
I am using Clojure 1.5, and reading a book on Clojure 1.3. I am reading over the namespaces chapters but I appears in my repl I can already access everything with its fully qualified name without a require. For example on this website, namespaces examplehttp://blog.8thlight.com/colin-jones/2010/12/05/clojure-libs-and-namespaces-require-use-import-and-ns.htmlthey show how if you try to use (clojure.string.split) without first using require you get a class not found exception... but it works fine for me. I also am able to use (clojure.test/is) , which makes sense to me why would i need to require it if I am accessing its fully qualified name... but i suppose there probably is a good reason.. I am just wondering why I dont need to require any of these libs but examples in the books and online show I do. I am assuming something changed in a latest version.

Re: Are all clojure namespaces loaded in repl by default?
The namespaces you mentioned have already been loaded and thus you can use the fully qualified name . What if you try (clojure.inspector/inspect [1 2 3]) in a bare repl???

Re: Are all clojure namespaces loaded in repl by default?
Generally speaking, you wouldn't care what has been loaded and what hasn't and you certainly should not rely on something having been implicitly loaded. The current best practice is to use :require in conjunction with :refer or :as, in all your ns declarations, thus avoiding the need for fully qualified names. Also, it needs to be noted that strictly speaking, Clojure doesn't preload anything for you...these namespaces just happen to have been loaded because Clojure needed them during bootstrap...Nothing really happens for the user - at least this is my understanding.

Re: clojure.core.async java.lang.IllegalArgumentException
Maybe hidden in the go macro expanded code. I do not have access to it (iPhone). You may want to use macroexpand and grep on the expansion. Just take your go block and wrap it in (macroexpand '(your form)) Don't forget the quote. Maybe the expansion will shed some light. Do not panic on the look of the expansion, the code shuffling is kind of heavy. Luc I do not have a single close! statement in my code anywhere.

Re: ClojureScript integration with Emacs/Cider ?
Great, let me know if you have any questions. I'm definitely planning ClojureScript support sometime soon. I think most of the symbol resolution for core cljs should work (since it's mostly the same as clj) for for pure cljs (including the core libs) everything at http://cursiveclojure.com/userguide/documentation.html should work. If you see anything that's not working either let me know directly or we have an issue tracker at https://github.com/cursiveclojure/cursive/issues. I'm also planning to handle JS interop but that's tricky because that support is only present in IntelliJ Ultimate. I'm still working out how to handle that but it's definitely on the roadmap.

But for pure cljs it should work pretty well. There are quite a few people using Cursive for cljs dev now, despite the slightly embarrassing lack of explicit support :-) Hi Colin, I just installed Cursive and looks very promising. I'll try using it. Do you plan to explicitly support ClojureScript? Do you have an ETA? That would be awesome, because viewing the implementation of Clojure's core libs is very valuable and from what I understand, there are differences between Clojure and ClojureScript (e.g. protocols are at the bottom in ClojureScript) and it would be valuable if I could click on a function and see its ClojureScript specific code and documentation. Also handling the Javascript interop would be awesome too.

Clojure deployment questions w.r.t. jars, clojure source files, compiled class files
So if I sample some clojure jars in my local maven .m2 directory, most of the jar files have only clojure code, and a project.clj. If I look at the org.clojure project there, it has many java class files, what appear to be corresponding clojure source files, and *no* project.clj. With only a little experiencing on some single AOT compiled modules, I wondered 1) When and under what circumstances projects are compiled in source versus .class form? 2) Why there is no project.clj in the org.clojure jar file? 3) When the clojure 'compile' function comes into play in your typical clojure project deployments? (vs. :aot targets or other leiningen deployment techniques). Any pointers or enlightenment on the above questions appreciated. I read the clojure compilation page, but I haven't quite put together what that's telling me about *how* to comjpile a file and gen-class a class, versus why I see all these clojure .m2 jar files with no classes whatsoever.

As are most of the Clojure contrib libraries too, although some are now starting to sport project.clj files to make local development easier. In the last round of development, I added Leiningen support to clojure.java.jdbc to make it easier to jack in with Emacs and test the code.

We only AOT namespaces that generate Java-compatible classes for situations where we must be natively callable from Java (e.g., we have a log4j appender written in Clojure). Within that AOT-compiled code, we require namespaces and resolve symbols dynamically (at runtime) to bind the Java-called code to the rest of our code base. Part of the reason is for the flexibility that source deployments provide: the ability to REPL into a live, running process and reload code from updated source files without needing to stop the world, for example. If you're relatively new to Clojure, I'd recommend completely ignoring the whole compilation thing unless you specifically need to generate natively callable code for Java to Clojure interop.

Re: Clojure deployment questions w.r.t. jars, clojure source files, compiled class files
Just to throw a wrench in this thread :))) a) We AOT our stuff to avoid shipping our sourde code to customer sites (:aot [regex...]), this requirement is the basis for what follows. b) We filter classes using lein to remove from our artifacts classes from other libs so only our AOT code is shipped in our jar files (:jar-exclusions [regex...]). This prevents mixing compiled classes of third party in our own jars which I agree can be pretty confusing (from which jar comes this compiled class ? Euuuh) c) We are strict on version control and obviously will not ship Clojure code compiled with different versions of Clojure, this is a recipe for disaster when there are feature changes in Clojure. We follow Orson's advice here, We will sell no wine before its time. We skipped some Clojure releases in the past and we moved to 1.5.1 by mid 2013. d) Most of the source code shipped comes from the open source libs we build upon. We can deploy site patches as source code and get them applied at app startup time when we need quick fixes in prod but they are not part of the build (otherwise they would not be called patches :) e) We also have Clojure data/code stored as part of the configuration and loaded on demand, it's been mixing fine with our AOT compiled aritfacts. e) We use an integrated nrepl console embedded in our apps and attach to it. We can investigate live in prod, apply patches live albeit with some limitations but as far as I can see AOT is not bitting us here. Restrictions have more to do with the app life cycle which we are improving along the way. f) We obvisously do integration tests using AOT compiled artifacts while dev testing is not to avoid time travels to stone age (edit compile restart hell) In our design most of the stuff is done in our supervisor process and each supervisor auto configures itself differently using plugins according to the local configuration and it has to run 24/7. I think we kept most of the dynamic benefits while meeting the goal in a). We have been using AOT for 4 years now. It's not at as hard as people think it is but you need a minimal understanding of the underlying machinery and if you come from a non Java background I agree 100%, it's not easy to find a path between the sand traps to get you to putt in the hole from dev to prod.

Re: Clojure deployment questions w.r.t. jars, clojure source files, compiled class files
To complement my previous post and in relation to this one, we use (if-not *compile-file* ...) to wrap expressions that cannot be AOT compiied (like loading configuration or connecting to external resources which you do not want to do at compile time but at run time only:) This confused a lot of people in the past trying to use AOT. For many the compilation phase and code execution are perceived as a single step. When working in the REPL you do not need to be aware of this. With AOT it's important to be aware of the difference when writing code in dev. Luc P.

Most Clojure projects ship in source form (and are therefore compiled to bytecode on demand as they are loaded). 2) Why there is no project.clj in the org.clojure jar file? It's built with Maven. As are most of the Clojure contrib libraries too, although some are now starting to sport project.clj files to make local development easier. In the last round of development, I added Leiningen support to clojure.java.jdbc to make it easier to jack in with Emacs and test the code. It still uses Maven for primary testing (on build.clojure.org) and packaging - and Clojure plus its contrib libraries are hosted on Maven Central (where they are retrieved primarily by Leiningen into other Clojure projects). 3) When the clojure 'compile' function comes into play in your typical clojure project deployments? (vs. :aot targets or other leiningen deployment techniques). At World Singles, we AOT compile very little of our code. We only AOT namespaces that generate Java-compatible classes for situations where we must be natively callable from Java (e.g., we have a log4j appender written in Clojure). Within that AOT-compiled code, we require namespaces and resolve symbols dynamically (at runtime) to bind the Java-called code to the rest of our code base. Part of the reason is for the flexibility that source deployments provide: the ability to REPL into a live, running process and reload code from updated source files without needing to stop the world, for example. If you're relatively new to Clojure, I'd recommend completely ignoring the whole compilation thing unless you specifically need to generate natively callable code for Java to Clojure interop. In case anyone is interested, our pattern for bridging from the AOT-compiled namespace to the rest of the code base tends to look like this: (def the-symbol (delay (do (require 'the.namespace) (resolve (symbol the.namespace/the-symbol) and then: ... (@the-symbol arg1 arg2) ... Our AOT-compiled layer is deliberately minimal and serves only to provide the Java-callable API so the rest of our code can be developed and tested in our normal interactive, incremental way. -- Sean A Corfield -- (904) 302-SEAN An Architect's View -- http://corfield.org/ World Singles, LLC. -- http://worldsingles.com/ Perfection is the enemy of the good. -- Gustave Flaubert, French realist novelist (1821-1880) -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Extracting a database schema and using it to synthesize and check SQL queries at compile time
Hey everyone, We've been exploring ways to make working with database code more efficient and less error prone. For complex queries, we prefer working directly with SQL. However, like for many others, a lot of our queries are very simple and repetitive. For example, retrieving or updating single rows, or a set of rows based on a foreign key. As an experiment, we wrote a prototype that uses the information_schema standard to automatically extract the schema from a database and represent it as clojure code at compile time. With this, we were able to synthesize some simple SQL queries. The interesting part of this is that the code generator automatically picks up primary key constraints and also performs validation on table and column names. All of this is done at compile time. Errors are caught early and the compiled code uses clojure.java.jdbc prepared statements. You can find the code and demo here: https://github.com/diligenceengine/edl I'm personally not a big fan of huge ORM systems, so I don't know where to go with this, if anywhere. Though it seems useful for building small macros for common patterns we have. Would love to hear if anyone has thoughts on the technique.
