Yeah, I second the motion of using the Emacs Wiki - that would be the most natural place for it.

Re: jde-xref works for some methods, not for others
I'm not sure what to tell you Raul. I haven't seen this behavior. If this is for some publicly available source, you could send me the source and I could try and reproduce it. Otherwise, it sounds like you are missing some data - and i suspect that maybe the superclasses of A and B may have something to do with it. There is an alternative to jde-xref, however, that Suraj Acharya has made as a plugin. It does not require a database, and works pretty well. You could ask him for it, or perhaps he could post it to the list so other people can try it out and give feedback.

Looking at the xrefdb directory, it looks like the database was created correctly... i.e. the appropriate -caller file looks like it has the correct entry for class B, with all its methods.

Re: xref help

Sure, just run the tomcat process adding -Xdebug -Xrunjdwp\:transport\=dt_socket,server\=y,suspend\=n,address\=9000 to the java command Tomcat uses. Then you can attach. You attach using jdb or JDebug. We also have some packages which live as *.jar files in WEB-INF/lib but where we also have access to the source code. Is it possible to tell JDEE about the directories for these packages, even if the running code comes from the *.jar files? Yes, it's possible. I do this all the time.

Re: Refactoring with JDE?
On Wednesday, September 3, 2003, at 07:19 PM, Nascif Abousalh-Neto wrote: Good point. What do you think should be the way to go with support for refactorings in JDE? I can see three major directions: 1) Expanding on the jde-xref functionality 2) Using the new semantic 2.0 - assuming it has all the necessary functionality 3) Use a Java-based backend or C-based, like Transmogrify or xrefactory. I think that using an approach similar to the JDE compile server, which keeps an instance of the java compiler running at all times, the Java approach may be feasible in terms of performance. Then again I don't know how Lisp-based grammars compare in terms of speed and memory usage with Java-based ones. I would think using semantic 2.0 is what we would want. From Paul's earlier email, I think he also is waiting on this. If semantic does not replicate the jde-xref functionality, we can change jde-xref to work on source files rather than class files by using semantic 2.0 to do the parsing. I'm certain it will be slower than what we have now, but it might be worth it. If we don't want to wait for semantic 2.0 we can implement some simple refactorings that use that functionality such as rename method with jde-xref. I had previously worked on such a system for doing refactorings, but ran up against a problem where I wasn't sure whether we should update the xref db based on the new refactoring or not. It's one of the strange issues that arise from us parsing class files instead of source file. Using a third party Java-based backend might be easiest, but I'm afraid that such a loose integration wouldn't give us many of the cool features we would want. My personal view, that is not shared by many I fear, is that we should do as much as humanly possible in elisp. The more we do in elisp, the faster and better integrated it will be.
Re: Completion for jde-open-class-source
This is nice. I don't believe there is a way to get a list of class names through reflection (doing so might be considered a security violation by the Java designers). So either we get the list through a recursive descent of the jde-sourcepaths or we do what you have done. Personally, I just use TAGS. JDE includes a tagsfile builder shell script in the scripts directory. The downside is it won't be as accurate as doing a JDE-centric command, as you have done. But I'm very happy other people are beginning to use the macros in jde-class.el! Suraj Acharya [EMAIL PROTECTED] writes: Here is my not so good way of getting class name completion for C-c C-v C-y.

I'd say it's possible with emacs, but we'd have to implement a previous-region variable, and if a user types a non-command key then if there is a region, it stores it in the previous-region variable. And once a completion fails (a user types in a non-keyword), we'd have to clear that previous region function. So, possible, but difficult.

Hi Andy, How about making nil default to the package of the class in the current source buffer? I'm not sure I want to make any assumptions. Typically, people would want their database to encompass more than one package. Plus, I anticipate that this will not always be invoked from a Java buffer. For instance, you could rebuild the database every night, and in that case you wouldn't be in a buffer. Also, I'd like to suggest renaming jde-xref-store-prefixes to jde-xref-packages as that more clearly indicates the variables purpose. Let me think about this one.

Paul Kinnucan [EMAIL PROTECTED] writes: I think it's nice to have all the jde-xref variables to have defaults that allow a new user to try it out quickly without having to do any preliminary setup, which is now required with your latest change. Previously, the default for this variable was to cross-ref the universe by default. I'm suggesting that we change it to cross-ref the current package. Is this what the user is likely to want ultimately? No, but it's a good starting point. The new user should quickly notice that the xrefing is limited and this should lead them to the doc to find out why. Xref already requires the user to set up the jde-xref-db-base-directory as well as the jde-built-class-path. There may be a way to automatically guess these things, but I couldn't see how with the jde variables already there. The base directory should usually correspond to something in the sourcepath, but we don't know which entry. And the jde-built-class-path cannot be figured out from the classpath, it's actually a subset of the classpath, but again we don't know what subset. So we need the user to fill out two things, with my latest change, it's now three things. I would rather force the user to fill out a reasonable value. I think not doing so will confuse users, and they may assume it doesn't work right.We could try to guess this one, but I think it would be an error prone process.I would like to minimize confusion and potential bugs, that's why I like the user to fill this one out. Let me think about this one. The thing is, the variable doesn't contain package names, it contains package prefixes. What's the difference? Well, it's that package (in the sense that something like com or org is a package), and all children of that package. To be specific, it's just whatever packages match that any of the prefixes in this variable, so the prefix co would match com.foo.bar. But the name is a bit confusing, I agree. I think this variable, whatever its name, should allow the user to specify the packages that the user wants to xref, including specifying that all subpackages of a package be xrefed, e.g., if I have a package structure like this: pkgA pkgAa pkgAb I should be able to specify pkgA and have everything in pkgA, including pkgAa and pkgAb, xrefed. On the other hand, if I specified pkgA.pkgAb, I'd expect only pkgAb to be xrefed. This is the way it works now. - Paul
Re: JDE-CVS-Commit
Paul Kinnucan [EMAIL PROTECTED] writes: In my ideal world, no setup would be required. If you did nothing, the JDEE would xref the code in the current package (or perhaps prompt you to enter a list of packages with the default being the current package) and store the result in the root of the project directory (i.e., where the prj.el file is stored). Further, you would not need to specify a classpath in addition to jde-global-classpath. The JDEE would be smart enough to process only those portions of jde-global-classpath where the packages that you specify live. Further, you would not even need to build the xref db. If there is no xref db in the db directory, the JDEE would build it the first time you executed jde-xref-first-caller. This would work great for the project I am currently working on here at the Mathworks. There are a lot of classes but they all live in the same root package. If the JDEE were set up the way I described, I'd just have to call jde-xref-first-caller to get started. No tedious setup. - Paul Your suggestions are interesting, and they are doable, I think. And I agree that having a no-setup solution is desirable. My problem would be that they do require some guesswork, and that guesswork may go awry, causing problems. Let me see if I can code something up that does what you suggest.
Re: jde-xref-store-prefixes queston
This probably is a bug. I recommend you keep this variable populated, though, but in the meantime I'll look into it. Schmitt, Christian (ext.)

ECB would then only call this jde-find-call-occurences-of-method-under-point. Question to Paul: Has JDEE already such a feature? As of JDEE 2.3.3, for which a very stable beta is available at the JDEE web site, yes, thanks to the efforts of Andy Hyatt. See the Cross-Referencing Classes section of the Searching Source Code chapter of the JDEE User's Guide for information on how to build and use a method call cross-reference database for a Java project. Hi Klaus, Some more information about jde-xref. It builds a cross-reference database by parsing Java class files. It includes three functions for navigating the database: * jde-xref-first-caller (C-c C-v a) builds a list of callers of the method at point in the current buffer and displays the first caller. * jde-xref-next-caller (C-c C-v n) displays the next caller on the list built by jde-xref-first-caller. * jde-xref-display-call-tree displays a buffer containing a mouse-sensitive list of the callers of the method at point. Clicking any caller displays the source for that caller. It would be nice to integrate these functions with ECB, e.g., first-caller and next-caller should work for the method selected in the ECB's class window. Also, it would be nice to be able (optionally?) to add a call-tree window to the set of windows that makes up the ECB desktop. That way, a user could 1. Select a method in the class window. 2. Select a Show Callers command from the ECB menu. A Callers window would appear in the ECB desktop. 3. Click a caller in the Callers window. Emacs displays the source of the call. - Paul

Re: Why the JDEE?
I had thought of this as well. Perhaps the JSwat maintainer would be interested in working on it. If you download the JSwat CVS code, you see they arleady use JDEE. See: http://home.nc.rr.com/nascifandelaine/jswat.el Paul Kinnucan [EMAIL PROTECTED] writes: Ralph Jorre writes: I don't often use a debugger but I have found JSwat very good and I just wonder if it wouldn't be more efficient to just include some hooks so as to be able to incorporate it efficiently. Maybe this would be easier to maintain than rewriting the debug. I plan to look into this. The problem is that the task of writing an Emacs front-end to JSwat may outway the advantage of replacing JDEbug with JSwat as the backend. In other words, there already exists a Lisp frontend to JDEbug. So it comes down to whether it makes more sense for me to spend my time on creating a frontend for JSwat or fixing the problems with JDEbug. Complicating the decision is the fact that I have created a generalized object-oriented debugger frontend, based on eieio. I decided to do this because jdb and the JDEbug frontends have a lot in common, e.g., essentially the same code for stepping and setting, recording, and displaying breakpoints. The generalized frontend allows both backends to inherit any improvements to the front end. I have already ported jdb to use the generalized frontend and am in the process of porting the JDEbug frontend to the generalized front end. It is conceivable that the generalized JDEE frontend could ultimately support three backends: jdb JDEbug JSwat In fact, I would prefer this as I believe there is value in having a backend that is tuned to the JDEE plus support for alternative backends as backups or to cater to user preferences for those backends. My preference would be for somebody other than myself to take on the task of creating a JDEE frontend to JSwat's console mode. This would free me to concentrate on the generalized frontend and on fixing the JDEbug backend. Developing a JSwat frontend basically entails subclassing the JDEE's generalized debugger frontend (see jde-db-debugger class) to support JSwat's console commands. This should be a fairly straightforward task. I'd be glad to serve as a consultant to anyone who wants to undertake this project. - Paul
Re: Why the JDEE?
I could not agree more. We love JDEE because we love emacs. Emacs will always be a better editor than any other IDE, therefore JDEE will always be better for editing then any other IDE. Throw in the compiling and debugging tools already there, and it's already an excellent tool. Hopefully people can add advanced functionality as needed, including plug-ins. I agree that debugging needs the most work, and I intend to help with that effort. Paul Kinnucan [EMAIL PROTECTED] writes: Dear JDEE Users, A number of recent threads have alluded to the need for the JDEE to keep pace, featurewise, with the competition, e.g., Eclipse and JBuilder. I'd like to present my perspective on this issue as the JDEE's lead developer and maintainer. It is hopeless for the JDEE to try to compete feature-for-feature with dedicated Java IDE's, especially commercial IDE's. The reason is that the pure Java IDEs do not face the difficult skills and architectural constraints than the JDEE development team faces, e.g., JDEE development requires both Emacs Lisp and Java skills and is constrained to standard I/O for interprocess communications. Why then bother with the JDEE? Because it allows Emacs users to use Emacs to develop Java code. Put another way, the reason for choosing the JDEE will always be Emacs and not the other way around. The JDEE allows Emacs users to make the transition to Java development without having to learn another environment. It also allows users who are, like myself, working in a multilanguage environment (e.g., C/C++/Java) to use a single environment for all their work. Where then should the JDEE development team focus its efforts. The focus should be on those features that best ensure that a decision to use Emacs for Java development does not entail a loss of productivity compared to what other environments afford. In my view, the JDEE's greatest deficiency in this regard is in debugging support. Therefore, it is my intention to focus my efforts personally in this area with the goal of providing the JDEE ASAP, not with the best debugger available, but at least one that does the basics well and reliably. Until then, other features that have been mentioned recently, such as a plugin architecture and syntax errors on the fly, will move forward only in so far as others work on them. Regards, Paul

Chris [EMAIL PROTECTED] writes: Hi all, I'm a Java et al coder who'd like to give emacs a shot. After 10+ years if never really loving my development environment, I finally grasp what's possible with emacs, and it seems that if I commit to it my IDE can be as good as I feel like making it. I have 3 main goals in the immediate future: 1) To make emacs a little friendlier for Java, C++, text, PHP, etc. In many cases this means making it more like Textpad, which is my current choice and is quite good off the shelf but of course isn't as flexible 2) To get my cash-strapped software team off of Textpad and using emacs (this is quite related to 1), and then extending it for our needs (JBoss/EJBs mostly) 3) To get good at this stuff and help out with the effort. Right now, there are a couple of things preventing me from comfortably coding in Java with emacs. One is file navigation; the other is control of whitespace. For file navigation, I really miss good ol' Ctrl-Tab. KDE seems to eat Ctrl-Tab, but if had some idea on how to make something similar happen I'd be pleased. I seem to remember some help on this previously (maybe on this list!), and as I recall some clever manipulation of the buffer list is necessary for satisfactory results. My problems with whitespace are that 1) I have no control over it -- I don't ever want to hit Tab and have nothing happen, 2) I don't know how to customize it, and 3) it looks like Emacs is not saving tabs as tabs (even though I thought I told it to), so that I can't pleasantly edit files that have been touched by Emacs. I'm not looking for quick fixes / code samples here; I'm willing to do some work, but I'm having a hard time getting started. By the way, Gnu sells a Introduction to Emacs Lisp Programming (I think), that's only available online. I can get by in Lisp, and I've read the online reference manual, but it's a little dry.

Re: Introspection based Java class browser....also demonstrates alittle bit of java and lisp integration...
This is interesting. I know you've mentioned it before. If this would help the JDE project, I could do this fairly easily. We have the class parsing code already, we just have to tie it into semantic. But since we are not using the latest Semantic, and as far as I know we have no immediate need to change the way we do introspection, for the time being, I will hold off on doing this. Eric M.

Your search methods can then call external programs, or whatever you like before returning a results table. There is an example that will search all Emacs Lisp symbols inside Emacs, regardless of having the sources available. The only part that needs to be done to make your new program support .class files is to extend the database.

I wonder if there's a place in here for kawa (http://www.gnu.org/software/kawa/). It would be ideal for java-elisp communication, since it's a scheme environment that runs in Java. It even has an elisp mode! Galen Boyer [EMAIL PROTECTED] writes: On Tue, 18 Feb 2003, [EMAIL PROTECTED] wrote: Sounds like a great idea! I would volunteer to re-write the Jalopy (http://jalopy.sourceforge.net/) integration package I put together. I could also take a stab at a re-write for the integration package for PMD (http://pmd.sourceforge.net/). Those Elisp-Java packages have an awful lot of code in common, and it would be really nice to create a standard way to create them - specially the bit about a standard way to integrate with the BeanShell. I would like to suggest also a standard way for those packages to present their output. A lot of them generate warnings or errors that go very well in a compilation mode buffer. I think this behavior can be abstracted as well. Maybe the beanshell could be viewed as an application server. Let me work through my thoughts. Would it make sense that java code that is executed through the beanshell not have to println(someElispString); but instead, any java code that is to be executed by the beanshell and subsequently eval'd into elisp, return a java datatypes transformable to elisp set of objects, like hashmap, array, ... Then, the beanshell could offer a set of classes which take these particular return objects and transform them into println's of elisp strings to be eval'd by elisp. The only part that doesn't seem clear to me is how to have elisp not have to understand the java code, its structure and exact names as well as its exact syntax. I'm thinking, first an eieio interface to elisp be required to be implemented by the elisp code of the package. A mapping layer, maybe xml, or just elisp list, be used to wire elisp class/method names to java class/methods. Then, the elisp package integrates with a particular elisp interface and the java code integrates with a particular java interface and the elisp to java is the black box that none of the two sides of code knows about, taken care of by the beanshell's black box. This would also allow java requirements for some particular need of the JDEE to be given to a willing java coder and the elisp requirements given to a willing elisp coder and the two sides actually code in their respective VMs without having to hook the two, fairly incompatible VMs up during development. Of course, what I'm thinking is that a JDE user could integrate some jakarta package by working with Paul on the java interface needing to be implemented. Paul or another of the elisp studs, then codes up the elisp side of the house waiting for the java coder to finish his work. Then, elisp becomes a client and the java code becomes the middleware implementing interfaces the beanshell application server will be executing. -- Galen Boyer

Re: Problem setting breakpoint with JDEbug
Very odd. This should work. To double check, perhaps you can execute these lines: (if (not (fboundp 'line-beginning-position)) (defsubst jde-line-beginning-position (optional N) (save-excursion (beginning-of-line N) (point))) (defalias 'jde-line-beginning-position 'line-beginning-position)) (if (not (fboundp 'line-end-position)) (defsubst jde-line-end-position (optional N) (save-excursion (end-of-line N) (point))) (defalias 'jde-line-end-position 'line-end-position)) Execute them by marking them as a region (using ctrl-space at the beginning and then moving to the end of the region) and then doing M-x eval-region. Does it still happen after you do that? These lines are from jde-db.el, and should insure that line-beginning-position is defined no matter what your system is. Perhaps you do not have these lines, or for some reason they are not executing. To be safe, you really should have a .emacs file. See the JDE manual on how to configure it to use JDE. It may help in this instance, although right now I can't think of a reason why.

Re: Newbie has been stuck for weeks tryig to get stop on breakpoint.
You do not need to start the program from JDE to debug it. You can start it any way you want (as long as it has those -Xdebug etc java params) and attach to it. This seems to be working for you. First of all, don't do Display-Variable. Just ignore the whole Display menu. At any rate, you can't display anything until you hit a breakpoint. It looks like your breakpoint is set, and is getting resolved. It must be valid. Either your program simply isn't running into it (this would happen if you set it on statup code, since you have suspend=n. ) or somethng else is happening. Everything you included looks good, so I'm guessing you probably simply aren't running into it. If you are getting any error in attaching or setting the breakpoint, go to the Options menu and set it to debug on error. Then try again, and send the stack trace.

Re: JDEE installer?
Althought we're getting off the topics of installers, I say I agree, but that doesn't mean GUI's. If emacs people like GUI's they wouldn't be emacs people. But we need better UI for jde in general. For example, what's with the C-c C-v keybindings? This is only one key off from the C-x C-c binding which exits emacs. Not good. And in the debugger, is there anyone who has not rebound jde-bug-step-over? No way anyone is typing C-c C-z n just to go to the next line! When debugging, things should work like in edebug - editing is disabled, n for next, c for continue, e for eval. This would help a lot.

Re: JDEE installer?
Gee, I really think you are being unreasonable here. I think JDE could improve in user friendliness. A lot of things in emacs-land can. That doesn't mean to switch to GUI's or anything. But JDE SHOULD be user-friendly. You can have user-friendly emacs programs, look at BBDB. It's usually not significantly more difficult to make things easier than it is to make them harder. It just takes a willingness to listen to user feedback, and a perception of what interactions seem to be pain points. If JDE was not friendly, people wouldn't use it, they would use Java-mode instead. Some people at my company do exactly this. I'm not saying JDE's UI is very bad, I actually think it's one of the better UI's in emacs-land. However, I think there is room for improvement. An example of a ui problem: I was showing my boss how to use JDE. I showed him how to attach to a running Java process and step through the program. When he asked how to see local variables, I paused for a second. I do this all the time, but I made my own keybinding for it. So I looked through the menu and found JDebug-Display-Local Variables. When we did this, though, it wasn't what I wanted, and he wasn't very impressed. I had to assure him that there was a very nice way to view local variables, I just could't find it at the moment. I later found it was at JDebug-Show Buffer-Locals. I think things that cause confusion like this are a real problem. If I can't find the command, it's as much a problem as if the command doesn't work. To me, there would be no difference. For this case, perhaps that Display menu item should be renamed something else, although I don't use it enough to know what would be more appropriate.

Let's face it, we're living in the 21st Century. Maybe I am too old for modern 21st century apps. Maybe not. I even used Linux with kernel version below 1.0.0, don't exactly remember which one. During my development career I used many advanced IDEs: Borland Pascal, Delphi, Borland C++ builder, JBuilder and some other. At last I fallen in love to emacs and after starting programming in Java to JDEE for emacs. Look, Emacs shouldn't be user friendly because it isn't for users. Emacs is for developers so it should be developers friendly. And it is! I assume you are Java programmer. If you have troubles with remembering just few function names how can you be good Java programmer? Java has much more classes and methods. And each new JDK release offers next sets of packages with classes. Development is all about learning. If just don't like learning change your duty. Actually I am not going to force you use emacs+jdee or other IDEs or change your programming habits. Emacs+JDEE is for java developers as well as other Java Builders. They are simply for different kind of developers. Don't change emacs! I love it as is. If you don't like it switch to different IDE. PS. Please, please don't send copy of your e-mails to my address.

I think the point of these keybindings is that they are easy to type. In any case, you are right about C-x C-c being easy to inadvertantly type. It is quite easy to hit the c and x and the same time when doing any number of commands that start with either C-x or C-c (which most emacs modes make heavy use of). One way to fix the problem of inadvertently exiting emacs is to add set the variable confirm-kill-emacs to something like y-or-n-p so that it always asks you before exiting. Yes, I see you are correct. This is not a unique problem with JDE. I have in fact turned on that C-x C-c keybinding because of this. I do still think that shorter keybindings might be nicer, though. And for debugging they are essential - they should be just keys (I have mine bound to f10, f11, etc) --Peter

Re: prj.el under source control
Actually, I think I misread your question. I thought you were asking if multiple prj.el files could be in affect at once - so that on going to a file, we would walk from the root directory to the current directory, executing each prj.el in between. If we do this (who knows, JDE may do it already), then you could easily do what you want, just put in your prj.el (add-to-list 'jde-global-classpath this/project/dir), etc. I think this may be frowned upon, since all setting of variables should come through customizations, but it should work. IMHO, we shouldn't have this policy where things have to be customized instead of just set, it seems against the free-wheeling nature of elisp.
