Clewn (http://clewn.sourceforge.net/index.html) provides an integration between gdb and vim. However to work it needs gvim/vim beeing |+netbeans_intg| enabled. However with USE="netbeans" flag, portage installs all the Sun Java suite, and this is bad. Please provide a suitable use flag to activate this feature only without all that dependencies. Reproducible: Always
The netbeans USE flag pulls in dev-util/netbeans, which in turn depends on >=virtual/jdk-1.3. I guess the default provider for that virtual on your system is sun, but there are others. This doesn't look like it's at all a vim bug, though. Also, maybe you're setting the netbeans USE flag globally? Have you tried just setting it for app-editors/gvim in your /etc/portage/package.use file?

This is not the point. I try to be more clear: 1) I want gvim/vim with the netbeans_intg feature. (see gvim --version). 2) I do not want Netbeans. 3) I do not want Java. This because exist programs, other than Netbeans, that use the 'netbeans_intg' feature to interact with vim/gvim (see Clewn). Is this possible?
You can try to dig out what exactly from netbeans is needed to build that netbeans support in gvim. Then we can talk about what we can do about it. I am not gvim maintainer but I am netbeans maintainer so I can help from the netbeans side of the problem.
(In reply to comment #5) > You can try to dig out what exactly from netbeans is needed to build that > netbeans support in gvim. Then we can talk about what we can do about it. In the beginning was the `NetBeans External Editor module'. With the `NetBeans External Editor module', gvim can be used as editor in NetBeans. ``The External Editor support module allows users a choice of several popular editors as well as the default editor built into NetBeans. [...] Currently we have integrated with a vi super-clone known as Vim and XEmacs.'' quoted from http://externaleditor.netbeans.org/ This integration relies on the `External Editor Protocol'. ``The External Editor module and the editor you have selected comunicate through the External Editor Protocol. [...]'' again from http://externaleditor.netbeans.org/ On the vim side (the one that interests me) this protocol has been extended to support integration with other tools ``The communication between NetBeans and Vim uses plain text messages. This protocol was first designed to work with the external editor module of NetBeans see http://externaleditor.netbeans.org. Later it was extended to work with Agide A-A-P GUI IDE, see http://www.a-a-p.org. The extensions are marked with "version 2.1".'' quoted from http://www.vim.org/htmldoc/netbeans.html *netbeans-protocol* ``The interface to NetBeans is also supported by Agide, the A-A-P GUI IDE. Agide is very different from NetBeans [...]'' quoted from http://www.vim.org/htmldoc/netbeans.html *netbeans-intro* Other tools that uses the `External Editor Protocol' to work with vim also exist. One of these tools is Clewn (http://clewn.sourceforge.net/). ``Clewn implements full gdb support in the vim editor: breakpoints, watch variables, gdb command completion, assembly windows, etc.'' quoted from http://clewn.sourceforge.net/index.html ``At startup, clewn forks an instance of GDB, sets up a socket, listens to this socket, and forks an instance of gvim that will connect to this same socket in order to establish a NetBeans connection between clewn and gvim.'' quoted from http://clewn.sourceforge.net/doc.html *clewn-starting* Currently, the use of the `netbeans' use flag for gvim compiles the `netbeans_intg' option in gvim (see gvim --version) and, as dependency, installs NetBeans. Suppose that I am interested in using Clewn. Then I need the `netbeans_intg' option compiled in gvim. \quote{ a) REQUIRED: ------------ GDB: gdb 6.6 or any previous version, starting from gdb 5.3 VIM: any version starting from Vim 6.3 with the |+netbeans_intg| feature enabled } quoted from http://clewn.sourceforge.net/install.html However I am not interested in NetBeans! In my opinion, the existence of these tools that uses the `External Editor Protocol' to work with vim, shows that it is a mistake that the `netbeans' use flag of gvim depends on NetBeans.
I looked in the related eclass little bit and it seems that the ebuild uses nothing from netbeans. From your comment it seems to me that 'netbeans_intg' is a legacy name, something like 'externaleditor' would make more sense. It really makes no sense to install netbeans and all of its deps (there is more than 100 deps in netbeans 5.5 afaik) just because one wants External Editor Protocol support in vim. Unfortunately I can do nothing about this, it's up to vim herd to decide to drop the dep on dev-util/netbeans. Up to that, imo, 'externaleditor' use flag would make more sense but that would not be aligned with upstream.
GVim compiles fine with the netbeans dependencies in /usr/portage/eclass/vim.eclass commented out, and works with Clewn even when when netbeans isn't installed. There is absolutely nothing from Netbeans that is required to either compile or run Vim with the netbeans USE-flag. Vim's Netbeans integration is just an additional commandline option to use a TCP/IP socket for debugger/editor control. Programs such as Clewn and AGIDE (http://www.a-a-p.org) use this same TCP/IP protocol to provide graphical debugging support in Vim. There are no run-time or compile-time dependencies on Netbeans; it's only named after Netbeans because it was a Netbeans sub-project that defined the text-based TCP/IP protocol. In fact, there isn't a single version of Netbeans in portage that includes the externaleditor module that implements this protocol. The oldest version of Netbeans in portage is 3.6, but the oldest version to include this module was 3.5.1 (http://externaleditor.netbeans.org) and sources have been removed from the main trunk. In short, the artificial dependency on netbeans makes absolutely no sense. There is no header or library dependency provided by netbeans. In addition, the USE-flag does not enable any features that the any recent version of Netbeans supports.
hello I'm one of the author of kvim (now dead, but still). The so-called netbeans integration in vim will just enable the given protocol to be compiled in vim, so that vim can talk with some external component (such as netbeans, but also with others). There is absolutely no reason why this USE flag should request netbeans to be merged, this is in my humble opinion a mistake. It should (or not) add the ./configure option for vim, but that's all. I tested, and indeed, vim compiles ok with the netbeans option enabled, and i have no java, no netbeans installed. I'm ready to answer some more question if you like.
First of all thanks everyone :) netbeans use flag doesn't DEPEND on dev-util/netbeans anymore. I've also edited the USE flag description a bit: app-editors/gvim:netbeans - Include netbeans externaleditor integration support. I plan to move over clewn from sunrise to gentoo-x86 this weekend. Thanks again :)
