ynohtna posted:On top of what Hollow Talk correctly states, upcase-region is also mapped by default to a key sequence that a new user may invoke accidentally before they have learnt the core of how Emacs works and - vitally - how to invoke the essential undo operation. Quite right. I still sometimes hit some of these functions without wanting to despite not being all that new to Emacs, and I'm glad it warns me instead of running weird commands.

In the videos for Emacs Rocks, what feature is he using to show where the file ends? It's a grey line along the left of the buffer where other editors would put line numbers. Actually, it would be below where the line numbers stop in other editors. Any other cool modes you emacs masters run that do little tweaks like this?

If you want those empty indicators in every buffer slap the following somewhere in your init files: code:Edit: Just to add to this the two biggest things you can do to make emacs look a lot better is a) use a decent font and make sure you're using a build that can antialias the fonts (any recent), and b) use a nice color scheme. More advanced would be hiding the menu (and scroll bars honestly). And a general list of 'modes' that I like:

orphean posted:(setq default-indicate-empty-lines t) Thanks buddy I really like seeing where my files end for some reason. I eval-ed this and immediately smiled. The more I think about how emacs lets your play with the global environment the more it seems like emacs should be more of a chaotic mess than it is. Instead it's a powerhouse of productivity and fun  Thanks for the list of modes to try out. I think I'll explore Helm next. It looks like a more advanced version of ido. I get tons of use out of ido so improving that sounds like a great idea. I recently installed company mode thinking I would have to muck around with backends before I got it useable and I am super happy to see that I didn't have to install anything besides the base package before it was very usable. By default it works similar to Sublime text where it will just pull words from the current file as suggestions. All emacs noobies like me should give it a shot as an easy way to get auto-completion going! Also, nzenburn is the best theme I have found so far, but the built in tango-dark theme is also very nice. Everyone else should post more about emacs

Company is miraculous. You don't need back ends to get some great use out of it, but back ends are largely not your problem, either; package and mode maintainers seem to do what's needed in my experience, without me having to fiddle with much. (IDE-like stuff like CIDER and elpy need the hand-holding to start an inferior process, but after that the completion comes "for free.") So much win.

So I grabbed Emacs yesterday after getting frustrated with the poor state of Python Autocompletion in Sublime Text compared to C#'s IntelliSense in VS2013. I sort of came into it with the mindset of "Well I'll pick either Emacs or Vim to have a go at learning, and if I can't wrap my head around it then I'll give in and keep going with ST3." Last night I felt like I might be about to give in, but I loaded it up at work today and just casually opened up my .emacs, took out the scroll and toolbars, saved it and had a look around the buffer menu and stuff, without needing to think too much. It's... not easy, I guess, just not quite as incomprehensible as I first thought it might be. It got a lot easier too when I gave up on using the C-[whatever] shortcuts to move the point and just went back to 'proper' keyboard cursor movement.

Give it time. People's .emacs configs tend to evolve over time (it never ends!  ). Do use whatever feels most natural, be it things like CUA Mode, cursor movement or some such. Be prepared to also get told years and years into using it about package x or y, which will magically solve a problem you've had, a hack you've been using or just make everything easier, making you question how you ever managed to live without it.At least installing packages has become easier with M-x list-packages...

Emacs is getting some discussion these days. Stackoverflow is making an emacs specific Q&A site. Also the Emacs mailing list is talking about just sticking with elisp instead of trying to get Guile scheme integrated. I know elisp isn't very well regarded as a modern programming language. I'm hoping to eventually learn elisp so I can make cool modes for emacs, but if the language is going to change in new versions or switch to Guile then maybe I should put off my studying. Surprise T Rex posted:It got a lot easier too when I gave up on using the C-[whatever] shortcuts to move the point and just went back to 'proper' keyboard cursor movement. Are you talking about using arrow keys instead of like C-f to move right? Because forget that crap I'm arrow keys for life. Anyway, emacs is all about setting up the system to be easy for you so if you decide not to do C-[whatever] then that is a valid choice.

It's just a very 1980s lisp dialect. If you know any other lisp, elisp will be very familiar and only a little bit frustrating. What takes time is learning the Emacs APIs, implicit and explicit. Even in a world where they migrated to a more modern runtime, most of that material would remain the same. Lastly, I would be very surprised if we ever escaped elisp. People have been talking about Guile or CL-based Emacs for 20 years, and it hasn't happened yet.

For Python completion I use Jedi (https://github.com/davidhalter/jedi) and for syntax checking I use Flycheck (https://github.com/flycheck/flycheck). Try out Jedi.el first. I personally use anaconda-mode because I use company-mode as my generic completer but I recall Jedi.el to be easier to setup initially. There's also a couple of all-in-one Python packages for Emacs. I tend not to like such solutions but to each his own: http://www.emacswiki.org/emacs/PythonProgrammingInEmacs#toc2 Surprise T Rex posted:Last night I felt like I might be about to give in, but I loaded it up at work today and just casually opened up my .emacs, took out the scroll and toolbars, saved it and had a look around the buffer menu and stuff, without needing to think too much.

I don't use hjkl in Vim much either: touch typists ain't got swag. Seriously, maybe it's because I did a lot of swimming when I was younger but the homerow, touch typist position has always felt very cramped when I tried it. I keep my hands floating at the sides of the keyboard near WASD and the arrow keys so I have no problem using the arrow keys and Ins / Del / Home / End / PgUp / PgDn.

Yeah, okay. I'm hooked. I don't know why I like it so much, but I'm actively looking for reasons to use Emacs over other programs where I can, now. Partly to learn it more, partly just because what I already know is awesome. Not had a chance to use it for Python yet, but I've got it set up properly now so I can have a go later on at trying to work on a Django site I'm developing, so we'll soon find out how that goes. I think I might be one of those people.

Hello Emacs friends. I've just ported my Vim setup almost entirely over to Emacs/Evil and it's great except for two minor things: I keep an Exuberant Ctags file in my .git directories that's updated with Git hooks on commit/checkout. Vim would automatically pick that up thanks to some magic in the Fugitive plugin and use it for navigation and completion. Is there any way to have Emacs automatically grab it? (I've already updated the Git hook to generate an Emacs compatible tags file, and selecting it manually works). In Vim I had the tab key remapped to send tab if the cursor was beside a line beginning or whitespace character, and call a completion function otherwise. Should that be possible to duplicate? On a less Vimmy note, does anyone in the thread use Ensime for Scala dev? I've been using it and it's great, but I'm kind of surprised that there's nothing in the command list about evaluating code from another buffer in a REPL. That's a killer feature of CIDER and the thing that got me into using Emacs.

Should that be possible to duplicate? Note that in most language modes Emacs uses tab differently from Vim. Instead of inserting a tab (or n spaces) , it will try to "do the right thing" with indentation. This is usually pretty nice (you hit tab once and the line automagically snaps to the right indentation level), but if you want Vim-style control or you want to insert white space in the middle of a line, you're fighting the Emacs convention. Not saying you can't do it. But you'll likely have to fight it every time you use a new language mode. It'll be an uphill fight.

Thanks for the Ctags and completion tips, guys. I'll do some tinkering.Notorious b.s.d. posted:Ensime is unfinished, but its principal author has stepped back from active development. If you write something to get this done, he'll probably accept your PR, but I don't expect to see new features from him otherwise. That's too bad. Hopefully it gets picked back up, it's been just the right amount of IDE power without jumping to something as heavy as Eclipse. e. Turns out sbt-mode actually does what I was looking for: quote:You can also send a region of code from an other buffer in the same project. First set the mark to the other end of the region to send and the point (cursor) the other. Then run the M-x sbt-send-region command. The command will skip any whitespace or comments at the beginning and end of the region. jony neuemonic fucked around with this message at 17:57 on Sep 21, 2014 |

Org-mode is fantastic. It's brilliant for whipping up quick internal documentation and stuff. Write it out in loose bullet points, add headings, C-c, C-e, h. You have a formatted HTML page, if a little bare-looking. If you haven't made good use of it yet you really need to.

You have a formatted HTML page, if a little bare-looking. You can style the html it generates with css and even with javascript, though. That might at least help a bit with the bareness: http://orgmode.org/manual/CSS-support.html#CSS-support If you find yourself using it more often like that, have a look at the Publishing module (http://orgmode.org/manual/Publishing.html#Publishing) as well. It lets you define "projects" and can format the html and copy it elsewhere, together with images, stylesheets etc. I practically live in org-mode, since I use that for all of my notes (and Emacs+LaTeX+RefTeX for writing), and it really is fantastic!

Just used tramp mode for the first time and it's amazing. On my linux box it works great without extra setup and I'm anxious to setup putty so I can remotely edit and browse folders from my windows 7 emacs install. But I'm confused as to if it is keeping a connection open for a long time or just making connections as needed? When I close a file and all the dired buffers, does that close the ssh connection? I also see a tramp-cleanup-all-connections function, do I need to call that with M-x when I am done?

If you're worried about leaving them open then cleaning them up now and then doesn't hurt. There are a few functions available for that (in addition to the one you found): https://www.gnu.org/software/emacs/manual/html_node/tramp/Cleanup-remote-connections.html Another neat thing to do with tramp is use it to get elevated privileges locally to edit root owned files or whatever. code:

That's clever. I think my first instinct would be to dig into the arcane buffer traversal functions in org-mode and write a command that cycles everything in the subtree under point to DONE. I'm not recommending this, more pointing out how the way I use org-mode is actually bad for my productivity.  e: BTW, http://emacs.stackexchange.com/ is now out of beta.

I've put my own Emacs theme online which is a little bit different from most themes: the point is not so much to highlight every syntax under the sun, but use the highlighting to partition the source in easily scannable pieces: https://github.com/aerique/emacs-theme-aerique I've always found themes that highlight too much, distracting and to not offer much above no syntax highlighting at all. Not too mention the colors are often too intense. So the theme just highlights the usual suspects like comments and strings (which are often a source of errors when not closed). It isn't really ready for public consumption yet though since it has an issue: it needs to be loaded twice. This is probably due to the theme inheriting from its own definitions. Does anyone have an elegant solution to this without putting variable names for custom colors in the global namespace?

So Emacs 24.4 is out. Great. There's a bunch of new features, but one caught my eye: eww, a new web browser. Turns out it's... not really good. Here's an input field. If I run delete-horizontal-space, guess what happens to this input field?  If you guessed 'it loving disappears', congratulations! Here's a password field. I'm going to type some text, and then run delete-horizontal-space. Keep in mind this is equivalent to typing your password into a shorter input field.   Now I continue typing my password.  Great
