Is there any facility in emacs (either built in, or through scripting) for comment-aware search? I tried to find that functionality in Vim, and I found some scripts that people had written... didn't work too well. That might be something that would really spur me to use emacs

Could you be more specific in what you're looking for? Not sure what 'comment-aware search' means.

I want to be able to search through files using arbitrary regexes, but I want to exclude comments from the search. I also want to be able to search ONLY inside comments, and exclude code. Ideally this would be aware of any style of comment, based on the file extension code:

I also want to be able to search ONLY inside comments, and exclude code. Ideally this would be aware of any style of comment, based on the file extension It's not ideal, but emacs regexps have escape sequences that match comment delimiters that should work in any language, so you can potentially search using these. Anything more than that requires advanced elisp skills. Well, advanced enough to iterate over comments and run search-forward-regexp on them while dealing with nesting.

Okay, here's a quick hack. What this does is walk through the output of a buffer like you'd get using M-x rgrep, and applies a filter function on the contents of the matching line to see if it's in a comment. If so, it removes it from the grep results. This is terrible, inefficient code but it gets the job done. It relies on the contents of comment-filter-functions to tell it how to figure out if part of a line of code is in a comment. py-in-comment-p comes with python-mode, which is available in ELPA in Emacs 24. You'd have to write your own predicates for the other modes you use. Then, just M-x rgrep, choose your criteria, then M-x comment-filter-commented-code on the *grep* buffer.code:

Okay, I figure this thread is as good as any to ask this question, since it's emacs related. I'm using Aquamacs on OS X 10.5 and I'm trying to set stuff up like this guy for Python + emacs. Most of the stuff worked fine (I think I ran into issues with just ipdb which is probably another question entirely) and I skipped a few of the config steps for now (like I didn't bother installing the python documentation locally). However, I'm not getting IPython to work at all. Whenever I bring up the py-shell it displays the Python 2.5 shell which is the last thing I want. IPython works when I launch it in Terminal and seems to be installed fine to work with Python 3 but for some reason it won't come up in Aquamacs. Both python-mode.el and ipython.el are in my load-path.. I'm not sure what else to try. Any ideas? Need more info to help?

I tried emacs on osx and there was this enormous toolbar that I couldn't hide. How do you not have that thing? Also the fonts were all gross and the method of configuring them was a thousand times harder than it needed to be.

etcetera08 posted:Okay, I figure this thread is as good as any to ask this question, since it's emacs related. ipython.el is a clusterfuck of not-working due to the various factors involved: * the version of Emacs you're running * the version of ipython you're running * the version of python-mode you're using * the version of ipython.el you're using * whether you're using virtual environments * whether your PYTHONPATH and PATH are getting applied correctly enough in between Emacs and your OS Right now, the most recent versions of python-mode.el (6.0+) do *not* work with ipython.el. The older versions (5.2 or so) do work, but break in other ways. You can trick python-mode into running an ipython shell, but it doesn't provide you the completion and other features of ipython.el. In other words, unless you're experienced enough to try fixing some of the issues involved (serious understanding of comint modes) the only thing to do is wait or find a configuration that doesn't piss you off enough. It's kind of disappointing; I'm dealing with the same exact issue myself. EDIT: The maintainer of python-mode.el is slowly working on getting ipython integrated into it, but it's probably going to be slow going for a while, and of course none of it is documented so there's no way to tell what even works. EDIT 2: Actually, I take it back. python-mode.el 6.0.3. seems to have a nice ipython integration without ipython.el (just M-x ipython within a python-mode buffer, works for me for Python 2.6.5 and ipython 0.11). Completion doesn't seem to work yet but I'm playing with it now. FINAL EDIT: Okay, yeah. The python-mode 6.0.3 is your best bet going forward. Looks like a whole bunch of things are going to be fixed in the coming versions, so it's just a matter of patience for the features you need, but I get the sense python-mode is going to become the de facto extension for interacting with Python/Ipython shells.

Let me know what version of Emacs, python, python-mode, and ipython you're running, and the results of (getenv "PATH") and (getenv "PYTHONPATH"). If you're receiving an error, evaluate (setq debug-on-error t) and then provide the traceback produced by trying to open a shell. If you've been swapping out libraries live, you may need to restart Emacs. I've found unload-feature doesn't take care of all the crap that python-mode creates (I'm not even sure I'm meant to use unload-feature in that way  )

For pdb support I seem to be able to just open up a shell (C-x M-m) and run my nosetests test suite at the prompt. When pdb open up it seems to figure out where files are and starts PDB mode. Maybe try that with your unittest test suite?

etcetera08, is it possible that the uninstallation/installation of python-mode didn't go properly? python-mode 6.0.2 defines a variable py-python-command, that should be set the executable of the python you want to run, I think. Since it's in python-mode.el, it should have gotten evaluated when python-mode was required. The fact that there wasn't a variable for that means something didn't get loaded correctly. Trying to narrow down my versions of everything to help you more. Could you post the value of your load-path variable? C-h v load-path RET

It seems emacs really needs packages (or bundled modules) for specific language environments. I'm thinking of packages like http://common-lisp.net/project/lispbox/. There's a lot to be said for just having stuff work 'out of the box' instead of having to search down all the relevant basic modules and executables (that could be packaged) you need to make developing code in whatever environment easier and then having to figure out how to get emacs to load those modules and then make configurations that most users would want.

I mean, the package stuff in Emacs 24 is completely rudimentary because they don't know what direction to take it in yet, but people are already using it for just the thing you describe. The Emacs Starter Kit I lambasted in one of the OPs has actually switched to providing all its useful modules and configurations into plain old packages that are essentially metapackages for the settings and snippets they feel are useful. I could see Emacs distribution servers, each one containing all the packages, settings, and useful functions for doing some particular thing in Emacs (The starter kit, for example, is focused on Ruby and Javascript).

Oh cool, an Emacs thread. I don't have any real Emacs tips to offer, but if you use Mac OS X you are probably aware that some of the simple control-prefixed key combinations work - like C-a and C-e and C-f and such. If you miss the meta-prefixed key combinations (in my case, particularly M-v and M-f), you're in luck - you can enable them by editing ~/Library/KeyBindings/DefaultKeyBinding.dict to look like this: code:(Trivia: There are actually two formats for this file, the old-style NeXT formatting, like you see above, and the new-style XML, which is probably the default on your system or you can see an example here. I had converted my file to the new style (or maybe a Mac OS X upgrade did it for me, I don't remember), but then recently I realized that I hit cmd-backspace expecting it to deleteWordBackward (which I believe opt-backspace does by default), but instead it is deleteLineBackward or something else. However, I couldn't get it to work - because, as it turns out, the @\U007F entry for cmd-backspace won't work at all in an XML DefaultKeyBinding.dict.) Addendum: If you're new to Emacs and you keep hearing about how it's got an email client and a web browser, some caution. Those things won't replace Safari and Mail (or whatever you use) for anything approaching "normal use". If youre curmudeony enough to be able to stomach using Emacs as your MUA, you're probably already doing it. Even jwz doesn't read his email in Emacs anymore. If you're aware of all this and want to experiment, then do so by all means... just don't expect GNUS to be a drop-in Gmail replacement. Like. At all. OTOH if you're way beyond this and just can't get enough Emacs, I recommend checking out conkeror. It's a browser based on Mozilla XULRunner, which means you get fancy new features like JAVASCRIPT and even BROWSER PLUGINS (unlike emacs-w3m), in a mostly Emacs friendly way. I've tried it several times and I think it's just not for me, but it's at least a step in the right direction. (Unlike, IMO, emacs-w3m.) You might also be interested in stumpwm, which is an X11 window manager written in Lisp in an Emacsy way with an Emacsy UI. When I tried it last, it was pretty nice, but I don't run Linux on the desktop any more so I never use it. Comedy option: Don't do any of that but instead use SXEmacs. In addition to being a mail and IRC client, SXEmacs can also be your X11 window manager and login shell! (Though apparently not at the same time; "We wouldn't recommend trying to run an X session from it" as your shell.) Terrifying. Fake edit: also, I have had caps lock mapped to control for years and I have some serious Emacs pinky right now (for the first time in my life). It loving sucks. Real edit: some binaries links for the OP, if you want them: On Windows, I used to get them from here. These binaries work, but they're old. They are the only ones to come with a workable installer. If you're brand new, you should probably start here... just click the "Download latest EmacsW32+Emacs patched" button from the download page. If you want Emacs24, you'll have to get it without the installer (which does stuff like register file associations and such) from the official alpha builds distribution point. On Mac OS X the situation is all so much simpler. You can get some good pre-built packages from https://emacsformacosx.com, including pretest releases such as for Emacs24 from the builds page. (The brew install method may also work very well, I've just never used it for Emacs.) equation groupie fucked around with this message at 20:45 on Oct 10, 2011 |

A little off topic, and you might already know this, but you can configure bash to work in Vi mode with $ set -o vi -- you can change it back with $ set -o emacs, so the keybindings are definitely emacs inspired, at least in the case of bash.

Nothing stopping me from writing one I guess (except laziness) Fren posted:The Emacs Starter Kit I lambasted in one of the OPs has actually switched... This just made it from completely horrid to mostly terrible. Other than a few things (like Yegge's effective emacs tips) I really think most people would best served by learning Emacs as is and making configuration changes organically. I admit I'm probably just being geezerish but I'm from the school of 'You should know what the hell that poo poo in your .emacs does'. Fren posted:Does anyone use a mixed mode for HTML and inline Javascript that's not a complete pain in the rear end to use and work with (i.e., nxhtml?) I'm glad I'm not the only one who doesn't care for nxHtml. I have some mental block when trying to use that drat thing. For just multiple mode support without alot of the extra cruft check out MultiWebMode (https://github.com/fgallina/multi-web-mode) Basically to use it you just setup a plist where the label is the name of the mode you want to use and the value is a regex telling it how to recognize the region for that mode. This is all documented. As a plus you can use whatever major-mode you want for each thing easily. Want js2-mode for javascript? Go for it. Want some funky custom mode for css? Sure, why not. Etc. For an actual contribution to the thread I present for the thread's pleasure: Common Lisp in Emacs.  For the 2 of you (am I being generous? Probably) who give a crap about Lisps (or Schemes, what have you) you will find no better environment than Emacs + SLIME. In that screenshot I'm also using AutoCompleteMode with the AC-Slime backend for the code completion stuff. And if you like your parentheses to look like fruity pebbles may I point you to rainbow-delimiters. Incidentally, AutoCompleteMode has a Semantic (part of CEDET) powered backend that does a good job offering code completion for C/C++ and a great deal else. There's also GCCSense which involves you compiling a customized GCC compiler of all things. That's a bit more hardcore. There's other options for completion but most of them involve crap like completions showing up in a separate buffer or in a tooltip or some such nonsense. Autocomplete works the way I want it to work (and as a bonus works without X).

I'm not the most experienced guy on the command line so I was thinking of putting a config that I like on a webserver and have a little script wget it and move it to the proper place for .emacs to be. Maybe you experts know of something better? Another approach to this would be to edit remote files in your local Emacs using Tramp. I still log into remote hosts sometimes to edit files sometimes, but I find it's so seldom that I don't need my full-blown Emacs environment. (And when I do, I usually use vi.  )Tramp is awesome -- just read the manual. I really like the rest of emacs, but even if I hated it, I'd have to hate it a LOT to leave Tramp behind.

Tramp is super powerful and can do a lot of stuff that might not be obvious at first glance. One of the things I use Tramp for all the time is opening read-only files. So normally you'd need to hop into a terminal, use sudo, open the config file, edit, save, etc. With Tramp you can do this without leaving emacs and without running an emacs with elevated privileges. Let's say we want to edit our /etc/hosts file. In Emacs we use C-x C-f to open a file as normal. But instead of just opening /etc/hosts (which will be read only since we're not retarded and don't run as root) we pass in the following for the file name: code:

Another hint if you're using emacs for any s-expr language like Common Lisp, Scheme or Clojure: ParEdit and Redshank modes constraint you to only s-expr, it becomes impossible to write unbalanced parenthesis and so on. You will have to get used to new commands such as joining and splitting expressions, but it significantly speeds up your Lisp coding. Check out the screencast on the Redshank link for an example.

Writing Lisp in Emacs is such an unbelievable pleasure, and the functionality so immensely powerful, that using any other tool for any other language feels completely primitive. It's kind of sad. I use rainbow-delimiters, but Paredit still throws me off often enough that I can't really work in it yet. But I do have the Hyperspec linked up through Info-mode, as well as being able to lookup the current word in the Hyperspec instantly. Still trying to work on the holy grail, that is: having one version of slime and swank that works with SBCL locally, SBCL remotely, and Clojure. And thanks for the tip on multi-web-mode!
