Re: ANN: Windows installer for Leiningen
Hello,
Should one have Powershell pre-installed? The wizard does not complete
successfully the self-install step, although it seems as it is not
aware of it.
When running lein self-install manually, I get a
DotNetMethodException (*). Now I'd guess this is an issue of lein.bat,
not of your installer, anyway it would be nice if your package could
embed all the hidden dependencies, as it already does for curl.exe.
Kind regards,
Roberto

Hi,
I've put together an installer for Leiningen on Windows:
http://leiningen-win-installer.djpowell.net/
Hopefully it should make it a bit easier for Windows people to get Leiningen
and a Clojure repl up and running.
It requires a JDK to be installed first, but other than that there aren't
any dependencies.
It should work on Windows XP and above, 32-bit or 64-bit. With or without
powershell available.
The installer should take the hassle out of setting up paths and environment
variables, and changing them when new JDKs are installed.
The current version is beta1. If you've got any feedback then give me an
email.

I'm doing some test, the problem seems to be this line:
powershell -Command {param($a,$f) (new-object

Where %~1 points to a path with a space inside:

[I can't believe both that in 2013 MS Windows does not handle such

It should be enough to do a smarter string concation; I'll try later.

[OT] Re: ANN clojure-doc.org (aka CDS), a new community-driven Clojure documentation site
I'm pretty sure you have already thought about it and it's me that missed your considerations, but why we are not using a wiki-based tool, like Wordpress, instead of forking a git branch? On Mon, Oct 8, 2012 at 6:25 PM, Michael Klishin michael.s.klis...@gmail.com wrote: ## Announcing clojure-doc.org I am starting a new thread because the existing one about CDS is now polluted by all kinds of off-topics. About a week ago, John Gabrielle announced CDS (Clojure Documentation Site): a new Clojure documentation resource for the Clojure community by the Clojure community. We are past dealing with all the plumbing and happy to announce that our work is now public at http://clojure-doc.org and you are welcome join the effort: we tried to make it as easy as possible. ## How It Works We have a repository on GitHub [1] that has Markdown files, toolchain setup instructions and several article stubs. The stubs help contributors pick a topic to write about and not worry too much about how to structure the document. They are training wheels for documentation writing, if you will. To contribute, for the repository [1], create a topic branch, make your changes and submit a pull request on GitHub. No contributor agreement process, no JIRA, no patches. Then an existing contributor will either merge your pull request or suggest changes. The toolchain currently requires Ruby *and* Python (for code highlighting). We decided that it's good enough for now. There are instructions about setting everything up in the README. There is no separate mailing list, so if you want to ask or suggest something, do it here. ## What We Have So Far Given that CDS is literally a few days old (after we migrated to the new toolchain and got to actual content), there is not much to show but a few tutorials and guides should give you an idea of what we want it to look like: * http://clojure-doc.org/articles/tutorials/getting_started.html * http://clojure-doc.org/articles/tutorials/introduction.html * http://clojure-doc.org/articles/language/functions.html * http://clojure-doc.org/articles/ecosystem/community.html * http://clojure-doc.org/articles/ecosystem/libraries_directory.html ## What CDS Covers CDS' goal is to cover more than just the language. It is certainly cruicially important to have good tutorials and comprehensive guides on Clojure. But when using Clojure in real world projects, you will need to know about the JVM ecosystem, Leiningen, how to write tests, what libraries are out there, how to profile code, JVM tooling for ops, how to develop and distribute libraires, and much more. So there is group of articles about the Ecosystem stuff: think Leiningen, popular libraries or how to use VisualVM to find hot spots and investigate concurrency hazards in your apps. This means that if you feel that documenting sequences is boring but excited about the ops side of software engineering, you can still contribute to CDS and enjoy the process. When documenting various tools, sometimes it makes more sense to just link to existing documentation, which is what we do for Leiningen. ## Low-hanging Fruits There are currently several articles that already have their structure in place, what is left is writing the content and code examples. For example, you don't have to be a genius or a Clojure expert to write articles such as * Books * Java interop * Collections and Sequences * Namespaces (ok, you *have* to be a genius to explain the ns macro well but some people certainly can do that) If you want to start working on one of those articles or have existing content you've authored that can be ported, please let us know. Topics like Concurrency Parallelism and Laziness will take more effort, this is why we did not bother with writing any initial structure for their articles. ## Call to Arms If your company uses Clojure or has interest in adopting it and has open source Fridays, hacker time or something similar, consider contributing to CDS. This will literally benefit the entire Clojure community, all the current and future users. Not only every single Clojure user benefits from better documentation, it also gets outdated way slower than that hot new open source library you wanted to tinker with. In other words, it's one of the best ways to invest of your OSS time budget (if you ask me). No contribution is too small: feel free to suggest grammar improvements, better code examples, submit pull requests with just one new paragraph or even a couple of spelling corrections. Editing and proof-reading is also a great way to contribute. If you have design and/or frontend development skills, you are more than welcome to make CDS more legible, easy to navigate, and simply better looking. If you need examples of what's possible, here's what 2 people could produce in about 6 months in their spare time: * Monger documentation:

Re: Error running clojure file.
Wrapping the huge sets into vars makes it work:
https://gist.github.com/3369040
The first literal set works if it contains just the first 3282 elements (
https://gist.github.com/3369092). One element more and it does not work
anymore (https://gist.github.com/3369101) - throwing a CompilerException

Maybe this is a JVM issue (

weird that its occurrence depends on whether we are defining a var or not.

Re: Attractive examples of function-generating functions
I don't have my own examples, anyway being a daily object-oriented programmer I'm feeling compelled to say that where function-generating functions prove their main practical power is in what I'd label man in the middle functions. Whenever I need to add behaviour to an existing OO method I have to subclass or introduce an indirection by interface, applying a decorator pattern et similia, or to apply some aspect oriented programming. Instead in Clojure you can more easily replace that function by an hooked-one ( https://github.com/technomancy/robert-hooke/) or by hand-written wrapping functions (http://vimeo.com/channels/fulldisclojure/38507385). If a Java programmer find a little weird the typical decorator usage of the java.io.InputStream hierarchy (based on class inheritance) to the point it's been proposed a different hierarchy designed on interfaces (see the PragPub Interface Oriented Design book), I guess that the possibility of writing compoundable chains of functions can further improve the general design of what we write day-by-day. So if you are searching for practical examples I'd suggest to look for such use cases, although their best application IMHO has to be found not in business code but in utility libraries/frameworks, such as ring handlers. On Wed, Aug 8, 2012 at 6:48 PM, Brian Marick mar...@exampler.com wrote: I'm looking for medium-scale examples of using function-generating functions. I'm doing it because examples like this: (def make-incrementer (fn [increment] (fn [x] (+ increment x ... or this: (def incish (partial map + [100 200 300])) ... show the mechanics, but I'm looking for examples that would resonate more with an object-oriented programmer. Such examples might be ones that close over a number of values (which looks more like an object), or generate multiple functions that all close over a shared value (which looks more like an object), or use closures to avoid the need to have some particular argument passed from function to function (which looks like the `this` in an instance method). Note: please put the flamethrower down. I'm not saying that looking like objects is the point of higher-order functions.

Texas, USA mumble-mumble years ago: totally captivating, fully engaging,
and thrilling and motivating. Hypnotic, it was.
Wow, thanks for the very generous words. Hopefully we'll start to see
more people playing with and having fun with Overtone and Quil.
Programming is not just for industry, but for expressing yourself too :-)
Exciting times!

You're the first person to spot that! It's me essentially creating a new physical interface on-the-fly using my MIDI controller. Really, that's the part I'm most proud of - it involves quite an intimate relationship between Emacs Lisp and Clojure. It involves the following steps: * Emacs creates an overlay for the new value to be controlled * Emacs tells Clojure/Overtone to wait for the next MIDI control event, and to then continue to send new events for that specific controller back to Emacs * On new controller events, Emacs finds the specific form that the controlled value resides in, gets updates the value with the new incoming value from Overtone, and then finds the surrounding form and sends it back to Overtone to be evaluated. * Awesomeness ensues! I even didn't suspect that Emacs would allow such graphical overlays, have any link to doc? Coming to the very exciting topic about interprocess comunication between Emacs and a Midi controller I'll look forward to your code - I hope you'd like give us at least a general overview of the architecture :) Thank you Roberto It'll soon be part of Emacs Live once I've ironed out the last few wrinkles so everyone can easily control Emacs/Clojure with a MIDI controller.

Re: Clojure for shell scripts
Maybe this experiment could interest you (clojurescript as a plugin of gnome): https://github.com/technomancy/lein-gnome In general, if AFAIK the main performance issue is the jvm startup time and the loading of the clojure.core library, one first solution could be keeping a single background repl process active, which could run in separated threads every shell script feed to it via a tcp socket. Every thread should live in a isolated sandbox in order to keep clean the overall environment. On Sunday, May 20, 2012, Edward Ruggeri wrote: Hey everyone!, I know this is an old story. I've played with clojure, but the main thing that has kept me from never looking back is the startup speed. Hello world! in Java takes me .303s, but just java -cp clojure-1.5.0-master-SNAPSHOT.jar takes 1.989s (sending C-d to close the repl even before it starts). Searching around here, I've found -XX:+TieredCompilation knocks me down to 1.581s and also -Xbootclasspath/a:clojure-1.5.0-master-SNAPSHOT.jar all the way to 0.938s. Incidentally, the same tricks with Hello World take me to 0.159s. Those were major improvements with very little cost; a huge win (thanks clojure list!). Any further easy tips and tricks? I'd like to get to the point where shell scripts aren't painful. It looks like other major hints are nailgun, and never restarting the repl during development. I took the liberty of printing some System.getCurrentMillis from clojure.main. It looks like it takes me 0.666s to enter the clojure.main main method, which I didn't entirely expect. There are several static members of clojure.main that need to be initialized, these members take ~.520s to initialize in total; almost all of this is initializing `Var REQUIRE`. Presumably this is when most of the clojure environment starts to get loaded?

Re: How to configure a Clojure library at runtime?
Instead of using alter-var-root you could use the binding form. On this
subject of factory methods you could find useful the following article,
expecially the with-implementation macro:
http://pragprog.com/magazines/2011-07/growing-a-dsl-with-clojure
IMHO that solution should not prevent the callers from instantiate
different implementations of the same generic API, even from the same
thread.

if (n == 0) return the factorial, else go to the loop label and recur

In a Java-like translation we could have:
int n = number;

Re: Standard Practice for a Canned Lexer, Parser, Analyzer?
I should not go with an automatic parser. Binary network protocols can mean a broad range of things :). If there is just a passive consumer (like a textual HTTP browser), you could consume all the binary data and then parse it, though I don't know if do exist a grammar for binary symbols (just found this: http://www.iwriteiam.nl/Ha_BFF.html). You likely are consuming a real time stream, so the binary data is the actual content, not a structured message. In general, high level network protocols are text-based: HTTP, telnet, POP, SMTP. There is some trick: - you can send binary attachments with SMTP or consume them via HTTP because they are encoded in a textual description (BASE64); - the FTP protocol is two-faced: the interactive command controls are sent via a textual protocol, whereas the binary data is sent in a binary stream (in a new TCP port). Low level protocols (TCP or IP) are binary protocols. The packets have a format (http://www.faqs.org/rfcs/rfc793.html) which can be quickly checked in a numeric way, not in a symbolic way. The check is not just on the format, but also on the content, via checksum redundancy bits. Just a parsing is not enough.

Re: Standard Practice for a Canned Lexer, Parser, Analyzer?
On Sat, Jan 30, 2010 at 1:04 PM, Michael Wood esiot...@gmail.com wrote: I have come across references to a declarative implementation of the DICOM-3 network protocol written in Common Lisp and I was wondering what that means, exactly, and how one would go about doing something for an arbitrary network protocol. Maybe you're referring to this document: http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.106.982rep=rep1type=pdf I didn't know this (medical) protocol. Anyway, its parsing is driven by some header control data: To the PDU parser, this message is simply an uninterpreted stream of bytes. The DICOM Upper-Layer protocol specifies a header for each message encoding the length of the following data field and some flags indicating whether the data field is a command message or a data object (and additionally whether the data field contains the complete object or is a portion of a long data field that has been fragmented into multiple messages). If the message is a command, our system gives the PDU parser pointers to the beginning and end (in the TCP data buffer) of the message. The ruleset contains rules for parsing commands using the same conventions and language as for parsing any other type of PDU. If the message is a data object, however, the buffer (and begin/end pointers) are passed to a different parser. This parser is also data-driven, using the data dictionary to decode arbitrary data objects. Each server/client has a state machine which processes those messages: it can guess what to do next by reading the header control data: The Prism DICOM code uses a finite state machine to implement the DICOM Upper Layer Protocol, parsing incoming PDUs, and generating outgoing PDUs using a production rule grammar As the system parses incoming PDUs it extends an environment which stores these variables and their values. The environment is accessible to any operation that needs values of data fields in the decoded PDUs. In Lisp terms, the environment is represented as a nested association list. That is, the entire environment is a list of components. It seems to me that there is no automatic parser generation from a grammar: there is a continuous consuming and parsing which check the data with the stored grammar, and after a recognized event it changes the machine's state, producing a proper output.

I'm neither an expert on this subject. :) Nevertheless I'll give you
my position.

blocks, class blocks: here the word block means very different
things). If you're going to write by hand you'll have to check all
these contextual points, and finally handle the validation process of
the source file as a whole.
Tools as ANTLR give you the chance to just specify the grammar
(allowed symbols and rules), leaving to them all the validation
checks. You can also give them a grammar and a set of events (called
template in ANTLR), which are automatically triggered by the parser
when it processes a given rule.
So this is the reason, in my opinion, of why the by hand way is not
very used. This topic is related to (external) Domain Specific
Languages, so maybe you can find interesting this:

Could someone educate me about what developers normally do when faced
with having to create a lexer / parser / analyzer, say for clojure?
Why would people go with a canned solution, i.e. ready-made like soup
out of a can, instead of by hand?
E.g. why did the Counterclockwise Eclipse plug-in for Clojure use
ANTLR , or why did in the Enclojure NetBeans plug-in for clojure use
JFLEX? Why in clojure itself is there a reader made by hand and not
using a canned generator?
Am I naive in thinking one should do that by hand? Is this archaic
thinking like those who still prefer building websites in HTML by
hand?
What's the advantage of doing that, say for clojure or in general? You
still have to learn how a given generator works. And you may be
limited by its design. What if you want fine combed control over how
things are parsed to get, for example, sophisticated syntax based
evaluation or inferences from cold code. E.g. like what Eclipse does
for Java and their “Java Models” and exhaustive “Abstract Syntax Tree”
nodes?
I hope some of you could be generous enough to enlighten me.

Re: reading a range from a large file
setLineNumber should not skip lines (at least officially - see http://java.sun.com/j2se/1.4.2/docs/api/java/io/LineNumberReader.html). If every line is of fixed size, in Java you could use a RandomAccessFile.

I can do this in java using traditional java way by using LineNumberReader's setLineNumber(int lineNumber) but i'm not sure how to interweave this in with clojure's file sequence operations. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Clojure group.
