I'm thinking the more I get to know Vim and the available plugins, the more it becomes like an IDE to me. I guess the same is true for Emacs. My advice would be to take on of those or any other open IDE and learn and extend them to the point that it's perfect for you. I can only give the same advice. I'm mainly an Emacs user, so I think I can fill in the parts you've missed below :-) Oh and (to everybody) Emacs is one thing especially: customizable. You have to work a bit with Emacs to really understand this (because most editors/programs are customizable these days). But enough advertising ;-) In short words, i am looking for an ide that can do this: - syntax highlighting - concurrent editing of multiple files (splitting) - tabs or buffer list - file browser - regex search/replace Both Vim and Emacs can do these basic features. Vim even provides a mechanism for saving and restoring editing sessions. A file browser is provided by ECB and I have never encountered any minibuffer issues you've mentioned below. I also never encountered any incompatibilities between different customizations and I'm running a lot. Of course you can't use two that do the same thing, but I think that's clear (and usually the last one overrides the first, so no issues there). Restoring and saving sessions is, of course, possible, too :-), see here[1] - autocomplete (on the fly, not on demand, and maybe smart? - identify structures/classes ) Haven't tried it yet, but for Vim word_complete.vim[1] seems to be what you're looking for. You should also have a look at Omnicompletion. As Emacs has hooks for nearly everything it should be doable with it as well. It's possible in Emacs, and how to set it up see here[2], the package you'll see in the link, CEDET, is a complete IDE framework and not just auto-completion (but you can use only parts of it!), it's used for example in ECB and JDEE[3] - project manager Don't know about that but it would be nice to have simpler project specific settings for Emacs/Vim. For Emacs there's EDE, it's part of CEDET. - symbol list/browser current editing buffer That's pretty much ctags/etags, maybe cscope. And in addition you can browse this stuff with CEDET, see[1] for details. - flexible build options that include scons, not just makefile You can put the following in ~/.vimrc: autocmd BufEnter ~/path/to/project/* set makeprg=scons In Emacs you can use whatever you want to build your project, because there is no classic restriction called project like all these new IDEs have, but if you want there's EDE. - code folding (with detection of blocks) Vim does it[2]; Emacs seems to have some kind of FoldingMode according to Google. Yes, there is, it's called hs-minor-mode. - lightweight/ergonomic interface (i dislike space being occupied by the bar that displays the line numbers, with a padding of 10px for example) Both of them are very customisable in this regard. If you've customized Emacs alot, and for Vim that probably true too, the startup is a bit slower, but you have several possibilities here: 1) start Emacs as server (that's just a normal Emacs but clients can attach) and edit your files by running emacsclient and in Emacs 23 (not yet released) you can daemonize Emacs and attach as many instances of Emacs as you want (even from ttys and X at the same time!) 2) start Emacs -Q (no customizations will be loaded) 3) use a vanilla Vim (which I do often when I'm editing config files) i don't desire gdb or valgrind integration, but would be a + Emacs features gdb integration and there's Clewn[3] for GVim. As for me, I'm rather using a separate screen[4] window in the same session. Why don't you desire that? What's the purpose of an IDE if you don't want an integrated debugger? In Emacs run gdb and then gdb-many-windows (then debugging looks the same as in all these IDEs, you have a stack window, local variables window, source view, registers and so on).

[gentoo-user] Wireless intel 4965 howto
Hi there! Is there a working howto of how to get the wireless connection to work? Its a built-in chipset, intel 4965AG, and it was working with kernel 2.6.24, but I fail with any kernel newer. 2.6.26 had serious problems with rfkill-switch, and the only way for me was to unload the driver module, switch on the wifi-interface, load module again and then it worked. A little bit clumsy, but it worked. With 2.6.27 I entirely fail to get any connection at all. The wifi-interface refuses to accept any ESSID. So, is there a howto that describes how to get wireless to work? Maybe in a way so that I switch on the interface and no troubles with rfkill, etc? Thanks in advance Alex
[gentoo-user] Installation questions
Hello, I have read that the LiveCD is dead, no mas, ka_put_ski. So I wondering when the installation docs (gentoo handbook) will be modified for Chapter 2: Choosing the Right Installation medium? Many of the other installation methods (alternative to the G Handbook) also require CDs, stages and snapshots. No 2009 profile yet? I have seen this page as a recommended (on this list) method to install Gentoo: http://www.sysresccd.org/Main_Page Maybe a quick list of instructions how to use it to install gentoo? Maybe a boot-floppy and then get everything from a usb stick for older i586/P1 systems? Many of the older machines I install gentoo on, do not support usb booting directly? Hell, for that matter, I do not know what to tell somebody new to Gentoo, to use to install on a computer now-a-days? Currently, I hack my way through using 2005 and 2006 minimal CDs until I find a combo of files/drivers that work for an old x86 arch (K6 and such too). I'd like to learn how other folks are performing Gentoo installations these days. I just used a 2007 minimal cd without incidence, but that seems to fading as a viable offering. I never had any luck with 2008* cds. Maybe a list of really simple steps on a usb stick? or a home-made catalyst CD? Particularly for old 586 and pentium 1 machines. It seems every install on an old x86 arch is a random walk to get to a minimal working machine They do make excellent firewall and DNS servers.

It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously. If such a conflict exists in the
dependencies of two different packages, then those packages can not be
