clooj, a lightweight IDE for clojure
Hi Everyone, I want to let you know about clooj, a small, simple IDE for clojure that I have been developing (in clojure). It's packaged as a single jar file (including clojure 1.2), here: https://github.com/downloads/arthuredelstein/clooj/clooj-0.1.0-standalone.jar Just download it and double-click. (I use clooj to develop clojure code every day at work.) You can look at the source code here: https://github.com/arthuredelstein/clooj clooj runs as a standalone application or you can embed it in other JVM programs. (See the README, below). This is an alpha release and I plan to continue further development. Feedback of all kinds and code contributions are much appreciated! :) Arthur Edelstein San Francisco -- clooj, a lightweight IDE for clojure --- the application clooj is a small, simple IDE (integrated development environment) for the clojure programming language. clooj is written entirely in clojure and uses a swing-based GUI. It is cross-platform (assuming Java 1.6 has been installed on your operating system), and runs as a standalone application or as a clojure editor embedded in another java or clojure application. The standalone version (containing the clojure core) is a single jar file that can be launched by double-clicking its file icon or by running java -jar clooj-XXX-STANDALONE.jar from the command line. To embed in java, call clooj.core.show(). --- the layout The clooj window contains three columns. The left-most column is a tree showing clojure projects and the source files they contain. The middle column is the source file editor. The right column displays inputs and outputs of clojure REPLs (read-evaluate-print loops). --- the source editor The source code editor offers a few simple things to make writing clojure code easier: * A non-traditional bracket-matching feature highlights in gray those brackets that contain the innermost form you are currently editing. * Mismatched or unmatched brackets are highlighted in pink. * TAB indents, and shift+TAB unindents. * Automatically comment-out (and un-comment-out) multiple lines. * When newlines are entered, the next line is automatically indented. * Press ctrl-ENTER to send either the nearest root form or the selected text to the REPL. * Source files are continuously saved in the background to prevent accidental loss of your work in the event of a crash. --- clojure projects Each clojure project corresponds to a project directory somewhere in the file system, containing a src directory. Inside the src directory is the source code hierarchy, composed of directories and .clj files. Note this directory structure is completely compatible with the lein and cake clojure build programs and you are encouraged to use one of these from the command line in conjunction with the clooj editor. Clicking different source files in the projects tree will automatically change the source file currently being edited, as well as switch the REPL to the appropriate namespace. --- read-evaluate-print loops The upper part of clooj's REPL display column shows the REPL history (inputs and outputs) and the lower part is a text area for inputting forms into REPL.

By choosing Restart REPL you cause a new REPL to be created for the currently selected project and the old one to be discarded, if possible. If the project directory contains directories named lib and/or jars and there are any jar files inside, these jars will be included in the classpath whenever the project REPL is launched.

Re: Tutorial about web development with Clojure
I have reorganised the code, made some refactoring and added new
functionality. For now, it is not just a blog but a more general
framework which you can reuse for your own webapps. It is here now:
https://github.com/dbushenko/Clojure-WebApp .
The enhancements:
1. Added validations for models.
2. Added URL-encoding functions in Rails-style. So, now if you define
a route like (route GET /post/show/:id post/show), you automatically
get a function 'post-show'. Calling it like this (post-show {:id 10})
will get you an actual route /post/show/10. I really like the
routing mechanisms in RoR and missed this functionality in clojure.
I will evolve the Clojure WebApp and will appreciate any help from all
of you. The feature requests are also welcome.
I think, that the main drawback of all the existing solutions in
clojure -- is lack of documentation. I plan to write a really detailed
guide of how to develop web applications with Clojure-WebApp in a
couple of weeks.
Again, don't hesitate to improve my code / documentation.

Re: clooj, a lightweight IDE for clojure
I am *very* excited to see this project, which I think could be a great addition to the Clojure world, particularly for newcomers and those of us who teach them. First critical reactions: - I put a high premium on auto-indendentation, and clooj seems to get this right when hitting return after typing some code (or in the middle of code) -- this is great and missing in some other Clojure editing environments. A big plus. But if one screws up the indentation I don't see how to say indent this properly again, in the context of what comes above it. Tab moves it to the right, shift-tab moves it to the left, but is there a way to say move it to the correct place? Actually, yes: one can do this by deleting the previous newline and hitting return again, but that's awkward, particularly if you want to go through a block of code and see if the structure is what you thought it was... you'd have to delete and re-enter each newline. - I just created a new project and I get a user prompt in the REPL pane but I can't type anything into that... so I can't actually try it... I click in there but I don't get a cursor there, and typing does nothing. In case it matters I'm running Mac OS 10.6.8 and java -version says: java version 1.6.0_26 Java(TM) SE Runtime Environment (build 1.6.0_26-b03-384-10M3425) Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-384, mixed mode) - How is one supposed to create a new .clj file and add it to the project? I see that you say that some stuff is to be done with lein or cake at the command line... and I guess some stuff like creating new files could be done with other OS-specific tools, and all of this is fine with me, but it's not clear to me what should be done how. I'm not suggesting that any more needs to be done within clooj itself -- just that it should be more clear what should be done where. I think that a hello world example that walks one through the process of creating a new project, adding a new, empty src file, adding code to that file, and running the code, would clear this up. Maybe also a second simple example that also adds one library... or something like that. - It would be nice if all of the basic editor functionality was discoverable via menu items. For example the indentation commands are mentioned in the instructions in the posting to the list, but since they're not in the menus a user may not realize they're there. (These in particular could be under the Source menu, but as a general rule it would be nice if all major features are *somewhere* in the interface.) - Longer term I agree with Shantanu that things like syntax highlighting and autocompletion would be great, and actually I'd put my all-time favorite feature even before those: arglist-on-space. I'm a total arglist-on-space fanatic and evangelist -- I think it's the greatest idea ever for supporting/speeding code editing and that it should be in every Lisp editor. AFAIK it is currently available for Clojure only in emacs and MCLIDE. If I were going to add one editor feature beyond robust auto-indenting it would be arglist-on-space. Again, I love this project! I hope that the comments above are taken as constructive criticism. -Lee On Jul 18, 2011, at 3:03 AM, Arthur Edelstein wrote: Hi Everyone, I want to let you know about clooj, a small, simple IDE for clojure that I have been developing (in clojure).

use of subseq on a vector which I know is already sorted
Hi everybody, I have a situation where I know that the sequence I have at hand is sorted but does not implement the Sorted interface. How can I use subseq for example on a vector without actually creating a sorted-set out of it which I think may be wasteful.. Am I mis-informed about creation of sorted-set being wastefull?

Construct map without associng nil values..
Got something like this:
(for [e entries]
{:filename (.getName e)
:comment (.getComment e)
:manymorekeys xxx})
Quite often I get nil as comments. Problem is that I don't want any keys
added for comment if there are none.
I could wrap the whole thing in a
(defn remove-nil-comment [{comment :comment :as m}]
(if comment
m
(dissoc m :comment)))
(for [e entries]
(remove-nil-comment {:filename (.getName e)
:comment (.getComment e)
:manymorekeys xxx}))
But yeah...
Thanks

Re: use of subseq on a vector which I know is already sorted
Hi Sunil, If you know that the input sequence is already sorted, then you can use take-while and drop-while in lieu of subseq.

Re: clooj, a lightweight IDE for clojure
Hi Lee, Tab moves it to the right, shift-tab moves it to the left, but is there a way to say move it to the correct place A very good point -- added to the clooj github issues. - I just created a new project and I get a user prompt in the REPL pane but I can't type anything into that... so I can't actually try it... I click in there but I don't get a cursor there, and typing does nothing. In case it matters I'm running Mac OS 10.6.8 and java -version says: The REPL input is the lower right pane. I think I should add some labels on each pane. - How is one supposed to create a new .clj file and add it to the project? Use the File New menu. I think that a hello world example that walks one through the process of creating a new project, adding a new, empty src file, adding code to that file, and running the code, would clear this up. Maybe also a second simple example that also adds one library... or something like that. That's a good suggestion. Overall I'd like to make the user interface more self-explanatory -- any ideas on how to do this would be very helpful. - It would be nice if all of the basic editor functionality was discoverable via menu items. For example the indentation commands are mentioned in the instructions in the posting to the list, but since they're not in the menus a user may not realize they're there. (These in particular could be under the Source menu, but as a general rule it would be nice if all major features are *somewhere* in the interface.) A good point. Added to the github issues. - Longer term I agree with Shantanu that things like syntax highlighting and autocompletion would be great, and actually I'd put my all-time favorite feature even before those: arglist-on-space. I'm a total arglist-on-space fanatic and evangelist -- I think it's the greatest idea ever for supporting/speeding code editing and that it should be in every Lisp editor. AFAIK it is currently available for Clojure only in emacs and MCLIDE. If I were going to add one editor feature beyond robust auto-indenting it would be arglist-on-space. Another excellent suggestion (added to issues). I think you're right -- arglist-on-space is very cool. Where do you think the arglist should appear? I think there's a tension between wanting to display it near where the user is typing and the need to not obscure nearby code. Again, I love this project! I hope that the comments above are taken as constructive criticism. Absolutely! Thank you very much for taking the time to give me so much helpful feedback.

Hi Meikel, I took a look at the source for subseq, and you're right. To be specific, when the comparison operation is either or =, seqFrom allows subseq to get to the elements of interest in O(log n) steps, whereas drop-while needs O(n) steps to do the same. On the other hand, it looks like when the elements of interest are at the beginning of the collection (using or = as comparison operation), subseq and take-while should perform the same, since subseq simply uses take-while to iterate through the elements of interest in this case. To make a long story short, when using or =, use subseq instead of drop-while, especially if the elements of interest are deep in the collection or the same collection will be accessed multiple times. When using or =, subseq and take-while should have the same performance. Does that sound about right? -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Aparapi
I am the tech lead on the Aparapi team here at AMD. We have heard of folks attempting to use Aparapi from Clojure (as well as Beanshell, Groovy and Scala), and we would like to followup with various communities to work out what would be needed to make this work. There are a couple of challenges, which I am sure can be overcome but which will be immediate. Aparapi currently uses the classloader to extract the bytecode of the 'Kernel' class and at present we need some javac debug artifacts to help us decompile the bytecode to OpenCL (primarily we need LocalVariableTable to determine the scope/name of local variables). I can see how to sidestep the local variable table, and can envisage that a customized classloader might be constructed to help us extract bytecode for synthetic (or dynamically generated) classes/methods. We announced recently (at AMD fusion developer summit) that we plan to OpenSource Aparapi in Q311. It would be great to work with folks with intimate knowledge of these alternate JVM languages to make them work with Aparapi. Gary On Jul 15, 12:17 pm, cej38 junkerme...@gmail.com wrote: Hello.

Re: clooj, a lightweight IDE for clojure
You may also consider building a plugin architecture for Clooj. For example, Leiningen support can be built by writing a plugin. That's an interesting idea. How do you envision a plugin architecture should work? From the top of my head it looks like it should be possible to safely maintain a global state. The global state can change when you switch from project to project or create/remove projects. Since it is Clojure, safety (due to concurrency) is less of a concern. Based on the Global state, you can choose to render different things for the various controls on screen. For example, if the current project contains project.clj and Leiningen plugin is installed then include a Leiningen menu in the menu bar (which should act on the current project). Similarly, if Marginalia plugin is installed then show a Marginalia menu item under Tools. A TextMate theme plugin may work by taking into account less amount of global states -- it should rather modify the way controls are rendered. So, the look-n-feel should be theme-able. The keyword here seems to be well defined global state properties, which could be hierarchical in order to be extensible.

Re: use of subseq on a vector which I know is already sorted
If the input is always going to be sorted, consider using a sorted-set or similar collection type to hold it in the first place. If you're going to need to refer to a particular subsequence repeatedly, and it's held in a vector, you might also consider using subvec after using loop/recur to find the start and end indices. -- Protege: What is this seething mass of parentheses?!

[meta] Google Groups/gmail support?
I can no longer find any forum or submission form for reporting problems to Google. You're a bunch of tech-savvy people using Google Groups and, probably in many cases, gmail. Do any of you know either: 1. How to report problems to Google nowadays, in such a way that they will actually receive attention rather than disappear down a black hole? 2. How to avoid weirdness like this: I was catching up on the long clooj thread, and when I was about halfway down suddenly the browser started spinning and then loaded the gmail login page with my username filled in but a blank password field! I didn't hit anything but MWHEELUP or MWHEELDN proximate to this event, so it seems as if somehow *someone else* clicked the signout link in the top right corner on my behalf. (The mouse pointer FWIW was nowhere near there and my hands were off the keyboard, so no mis-click or mis-key could have caused it.) This should not be possible, yet it happened. Worse, the back button did not DTRT and return me to the page I was reading and my position partway down that page, even though it should have still been in my browser's cache after such a short absence (ten seconds? Less?). So I wound up losing my place in the thread and it took me several minutes to find the exact right spot again. Obviously frustrating, and since I didn't do anything wrong to deserve such frustration, this behavior of the browser is obviously incorrect. AFAICT, this falls squarely on Google's shoulders no matter where the bug is: Google Groups is their responsibility, gmail is their responsibility, and the browser I was using was Chrome, which is guess whose responsibility? So, does anyone know what caused this and how to make sure it never, ever, ever, ever, ever happens again? I do NOT want to be in the middle of reading ANY page and suddenly have my browser deciding, on its own initiative, to navigate itself to some other page. EVER. It's MY browser. It goes where *I* tell it to, when *I* tell it to, and NOT BEFORE, and I wish to know how to actually enforce that -- which I shouldn't even have to, as that should be its natural behavior anyway! And don't tell me to ditch Chrome and use Firefox. Recent versions of Firefox have a very similar and inexplicable behavior that can strike on any page and that happens much more frequently: if anything at all slows down the computer, such as something else paging or wool-gathering, Firefox 4 and above will blank the page you were in the middle of reading and hide the tab bar and show a spinning-wheel mouse cursor for a while. Or sometimes, inexplicably, jump to the last YouTube page visited (why YouTube?), render it shoddily (usually with most of the page elements surrounding the media player missing), and sit there unresponsive for a while. Then eventually jump back. I'd take anything else, including a temporarily-nonresponsive browser frozen displaying the same page I was on (which I can at least continue to read until I hit the bottom of the screen!), over that. -- Protege: What is this seething mass of parentheses?!

Reflection warning on protected methods
Hi, I work on a project that's heavy on the Java interop. I've been working through it trying to eliminate reflection (I'd like to build unsigned applets). Anyway, I haven't been able to eliminate the reflection warning on paintComponent in this example: (set! *warn-on-reflection* true) (proxy [javax.swing.JPanel] [] (paintComponent [#^java.awt.Graphics g] (proxy-super paintComponent g) (.fillRect g 100 100 10 10))) It's also been brought up on StackOverflow here: http://stackoverflow.com/questions/1524614/how-do-i-typehint-away-this-reflection-warning I've tried it on Clojure 1.2.0 and 1.3.0-beta1. Is there any non-AOT way to do this? Is this considered a bug or a feature? :) Thanks! Dave -- You received this message because you are subscribed to the Google Groups Clojure group.

Threading operator generalisation
Maybe you might find this useful
(defmacro -
([x] x)
([x form] (if (seq? form)
(with-meta (replace {:? x} form) (meta form))
(list form x)))
([x form more] `(- (- ~x ~form) ~@more)))

nil

Re: Error running Clojure 1.3 in Eclipse
The stack trace shows: Caused by: java.lang.UnsupportedOperationException: Cannot recur across try at clojure.lang.Compiler$RecurExpr$Parser.parse(Compiler.java:6045) This looks like an incompatibility between your code (or something you're using) and Clojure 1.3.0. You can't have recur inside try - see http://dev.clojure.org/jira/browse/CLJ-31 - sounds like it was allowed in 1.2 but didn't work properly so now it's been disallowed? I notice that your project file refers to old contrib 1.2.0 - that won't run on Clojure 1.3.0 as far as I can tell (I had to update CongoMongo because of 1.3.0 compatibility problems that seemed to stem from contrib 1.2.0).

Re: Threading operator generalisation
Requests for a more general threading macro are usually met with a
link to the thread where Rich says this is not needed and we should
not encourage functions that need threading anywhere except the first
or last position. I don't have the link handy (sorry).
The usual objection centers around the fact that whatever symbol is
used for the binding position then becomes a varying thing within
the expression:
(-newthread- x
(str y :? z)
(str a :? b)
println)
Here :? means two different things which seems counter to how Clojure
works elsewhere...

Re: Threading operator generalisation
Ups, I'm not aware of that thread...I just found a more general threading
operator handy sometimes.
I do kinda agree that we shouldn't necessarily encourage threading in arbitrary
positions.
However, I can't quite follow your second argument.
While it does mean two different things, I don't see the problem with that.
We could use _ instead of :? to indicate we don't care about the 'meaning'.

Re: Error running Clojure 1.3 in Eclipse
Hello.
Warning: *print-detail-on-error* not declared dynamic and thus is not
dynamically rebindable, but its name suggests otherwise. Please either
indicate ^:dynamic *print-detail-on-error* or change the name.
Since 1.3, the default behavior of vars is non-dynamic/un-rebindable.
So, when you (or its developers if it comes from libraries) define a
dynamic var, you have to write:
(def ^{:dynamic true} *print-detail-on-error* default value?)
[1.2-compatible form]
(def ^:dynamic *print-detail-on-error* default value?)
[simplified form for 1.3 and latter]
... change the name means that the name *foo* suggests it's dynamic
by convention, so if you added stars for emphasis, you should remove
them.
Thanks.

Re: Threading operator generalisation
Just as a general comment: just because any of our idiosyncratic functions and
macros aren't accepted for inclusion in Clojure proper does _not_ mean that
they can't find a full and vigorous life in their own libraries. Clojure is
readily extended and improved without adding bits to the language itself, and
Clojure development benefits from a very capable dependency management
infrastructure; take advantage of it!
In this particular case, I'll bet that someone has an arbitrary threading macro
in a library somewhere you can use…or, you can create such a library. Given
the number of times this has come up, I'm certain it would find some love.

I'd go for one that uses a normal symbol, e.g. (-x a (expr1) (foo a 3) (bar :k a 7) ...) where the symbol to be bound is explicitly provided by the user. It isn't desired that often, since collections tend to be the last argument and maps tend to be the first, but there are some cases where one changes type partway through (e.g. works on a collection, then extracts an element and works on that) or a function takes an argument in an awkward place (e.g. nth takes the collection first, not last).

Re: clooj, a lightweight IDE for clojure
Arthur, I can't thank you enough. Two great news in a week, that's awesome. I am eagerly awaiting Wednesday. But please, please, please DON'T ABANDON THIS PROJECT. CLJ Hackers, Please lend a hand. You have no excuse; it is written in Clojure. This is what Clojure needs the most!

Re: clooj, a lightweight IDE for clojure
I can't thank you enough for this Arthur. But please please don't abandon this project. Clojure hackers have no excuse to lend you a hand since it is written in Clojure. A newbie IDE is what Clojure needs most. Scheme was used as a first language so why shouldn't people be able to start with The Last Language. Why should people start with a broken model to think about their problems when they can start with the correct onehttp://www.infoq.com/presentations/An-Introduction-to-Clojure-Time-Model? An IDE such as CLOOJ is essential towards this goal. ~~Wish list~~: - A more memorable name would be CLIDE. - Java Web Start - Swing doesn't make nice UIs. - CLOOJ for ClojureCLR. David Miller's huge efforts were not rewarded with a similar IDE (vsClojure was abandoned). Thanks again -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: clooj, a lightweight IDE for clojure
On Mon, Jul 18, 2011 at 5:14 PM, abp abp...@googlemail.com wrote: Why is it necessary to press TAB at all? Couldn't auto-indent be the default for a line and only manually reindented lines opt-out until one opts in again using TAB or something? This is an interesting thought. On the other hand, when lines are merged or split, where does this status go? I'm thinking when a line is split the second of the two resulting lines should start out indented correctly relative to the first, and inherit the first's status; when two lines are merged, the status of the first of the two becomes the status of the merged line. This is consistent with the status being an invisible metacharacter at the start of the line that is deleted with the immediately preceding newline and cloned if enter is hit in the middle of that line. What about multi-line pastes? If the paste is of material cut or copied from inside clooj, the status of each line that was cut or copied would be stored OOB somewhere and used for the paste. (Actually using funny extra characters inline in the copied material has problems if material is copied from clooj and pasted into something else, such as a post to this list.) From outside clooj? Some sensible default, such as autoindent off (keep paste's formatting) or on (auto-fix to context). Maybe let the user choose either in an options screen. Saving the state across sessions also seems to need to be OOB. Putting it in the .clj file at the start of each line would gum up other tools, and adding clooj-internal comments to source files isn't much better. A clooj.dat file in the project root? Alternatively, avoid the mess and just always maintain structure-determined indent of all lines at all times. Does anyone really want fully user-controlled indenting outside of comments anyway? Spaces and tabs in the indent can just jump you to the start of the forms on the line, and self-insert normally in string literals and in ; comments, and single spaces normally anywhere (maybe turn tabs into spaces and tab or space next to a space just moves you to the right of the space). Or, the traditional thing: full control, but tab or something will reindent the current line, or all lines intersecting the selection if any, to structurally-correct positions based on all of the code above, if tab is hit outside a string literal or ; comment. -- Protege: What is this seething mass of parentheses?!

Hi Tuba,
Are you quite sure that #{\a \b \c} is not what you want? In Clojure's
notation, a backslashed character [more or less] refers to a
single-character string--something akin to the char type from C. Hence \a is
the character a. On the other hand #{a b c} is a set containing three
Clojure symbols, which is probably not what you want.
(If you want to be using a, b, and c as some kind of identifiers, take a
look at keywords.)
