So, what completion engines are people running here that they are happy with?

I've been using Helm (was: Anything) for more than a year now and am pretty content with it. I'm also still using auto-complete.el and Slime's own fuzzy completion (because ac-slime was slow as gently caress) and once I have consolidated the latter two into Helm it should all feel a little more consistent.

The one thing I would like is for the Helm buffer to open in the biggest available other-window, but I haven't been able to write a correct elisp function for that.

(Written on mobile so I can't be bothered to check for the correct names and provide URLs, sorry...)

I've got a problem with for loops in eshell.

If I do:

code:

for GPLOT in gnuplot_scripts/*.gplot { echo "Processing $GPLOT..." }

It'll echo all the scripts in the directory like it should, but if I do:

code:

for GPLOT in gnuplot_scripts/*.gplot { echo "Processing $GPLOT..." ; gnuplot $GPLOT 1> /dev/null 2> /dev/null }

It'll go into an infinite loop processing just one specific file. It'll do the same if I leave out the echo command.

Googling hasn't helped much, anyone got an idea?

I spent a ton of time a few months ago building a config with sensitive info (i.e., IP addresses, user names) in one file and the generic stuff in another, just so I could put it up on github or bitbucket or whatever. Still haven't done it.

I even set things up in org-mode.

I've been tempted to redo my config in org-babel like Sacha Chua did: https://dl.dropboxusercontent.com/u/3968124/sacha-emacs.html (from: http://sachachua.com/blog/2012/06/literate-programming-emacs-configuration-file/)

Have you tried M-p and M-n? It might be because I haven't had my morning coffee yet but AFAIK those keys are the defaults for moving back and forward through history for a lot of modes.

You can also do "C-h m" (describe-mode) to see what keys are bound for the mode, maybe it's listed there.

If I have some 'template' that looks like
code:
void foo_X(int Y);
and I want to insert this multiple times with different values for X and Y, what's the easiest way to do that?

I'm not sure it is the easiest but YASnippet is a nice templating library that will be able to do this.

http://ergoemacs.org/emacs/yasnippet_templates_howto.html

Here's an example I made for xsl:choose:

code:

#name : xsl:choose
# --
<xsl:choose>
  <xsl:when test="$1">
    $0
  </xsl:when>
  <xsl:otherwise>
    $2
  </xsl:otherwise>
</xsl:choose>

Your template would look something like this (untested):

code:

#name : void_foo
#--
void foo_$1(int $0);

IIRC, $0 is where you want the cursor to end up once the template is inserted. $n (n>1) are fields you can step through with TAB before ending up at $0.

I don't use a package manager for Emacs so take this for what it's worth.

PlesantDilemma posted:

I see both a yasnippet and sublime folder under .emacs.d/elpa/ should I delete those folders?

You could start with just moving / renaming the folder and see how that goes. There's probably some init file somewhere loading those so Emacs will still complain it can't find sublime and yasnippet.

I have no idea where the package manager stores its configuration but doing a

code:

egrep -Iir sublime\|yasnippet .

in the .emacs.d directory or your home directory should give you some pointers.

Hey, does anyone use keybindings other than M-w and C-w for copy/cut ? I don't like M-w for copy, but I don't know what other keybinding to use. I'm afraid I'll overwrite something useful that I just don't know about yet.

Don't be afraid of that. Emacs is meant to be customized.

I've been using a evil-mode for a couple of years now which gives me Vim-like behavior, before that I had extensive custom keybindings of my own. The last iteration of which converged to what is considered default for standard Windows and Linux apps. So C-z, C-x, C-c, C-v for undo, cut, copy and paste. C-a for selected all. C-PgUp and -PgDn for cycling through tabs, etc. etc. It was nice but I had used Vim in the past and preferred that.

Before that I had really my own custom bindings which were pretty optimal and nice but too different from other apps which irked me.

A reason to get familiar with the Emacs defaults would be that the Bash[1] shell uses them as well, but those can be rebound as too.

[1] the readline library actually so the key bindings return in more apps

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."

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

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.

Yeah, like others already said gently caress that poo poo. 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.

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).

I think I've seen a page on the EmacsWiki about updating tags on saving the buffer but I haven't used it myself (yet, I've been meaning to).

Ah, here. Not quite what I thought it was but hopefully some inspiration for your first elisp project ;-) http://www.emacswiki.org/emacs/GnuGlobal#toc3

Yes, there's a couple of solutions. Check this page which seems to have grown since the last time I checked it: http://www.emacswiki.org/emacs/TabCompletion

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?

OK so, I'm about 4 days into using evil and I like it but it feels like the model I use to manage buffers doesn't really work with emacs.

Basically, I rebind shift and left/right to move to the previous/next buffer. Then I use lots of splits and use up/down/left/right to navigate the splits. The problem is that emacs/helm makes tons and tons of buffers so rather than left/right navigating through the stuff i'm working on, it navigates through buffers that I can't even use because they're just storing something for helm.

I'm 100% sold on emacs otherwise but this is just killing me. What am I doing wrong?

You're not necessarily doing anything wrong, you just need to adapt Emacs to your preferences. I also use (alt-)up/down/left/right to navigate splits, I've also got a key bound to quickly switch back to the previous buffer and I have customized the "display-buffer-alist" variable (check what it does using "C-h v" or "M-x describe-variable"). The latter makes sure specific buffers open where and how I want them to.

Let's say you start using a new mode because you're learning a new language or something. Among other things it'll have its set of key bindings to learn. They'll probably build on existing emacs bindings.

I've rarely found this to be an issue.

The bindings that come with modes are almost universally crap just like the default Emacs bindings are and you'll never use all the bindings that come with a mode anyway.

Just "C-h m" and bind the ones you need to something useful.
