I am trying to install emacs prelude into emacs. The only thing I found after googling is this page, which tells me to clone prelude into
C:\Users\your_user_name\AppData\Roaming\.emacs.d
But I need to have prelude in the emacs system folder because I need to make my emacs folder a zip file and usable on other machines.
What I tried so far (unsuccessfully) are:
1. Download emacs 24.5.1 from gnu ftp site, and decompress to c:\emacs
2. git clone git://github.com/bbatsov/prelude.git
3. mv prelude/ /c/emacs/site-lisp
I thought step 3 should populate the emacs system-wide startup folder site-lisp, and allow prelude to load on emacs startup. But it didn't happen. I loaded a Haskell .hs file into emacs, and the Haskell mode isn't automatically activated as the prelude documentation suggests.
Can some one please explain how to correctly install prelude into emacs system-wide?
Thanks
You've "populated" the Emacs site-lisp folder in the sense that you've moved the prelude directory in full to site-lisp. While this would -- in conjunction with require-ing accordingly in your configurations -- be sufficient for "installing" Emacs packages, Prelude is not an Emacs "package" in the strictest sense of that word. Rather, Prelude can be thought of as a pre-defined set of configuration files, and this is why Prelude is generally cloned either directly into .emacs.d or symlinked to from there; it is not a package to require, and therefore does not belong in site-lisp.
The good news is that this makes your goal of making Emacs + Prelude usable on other machines relatively simple to solve with, say, a Bash script that:
Installs emacs in the corresponding manner for the current OS/distro/etc.;
git clone git://github.com/bbatsov/prelude.git path/to/local/repo
ln -s path/to/local/repo ~/.emacs.d
cd ~/.emacs.d
Note that the above is essentially the "manual" installation instructions provided at the Prelude website.
To make Emacs "portable" across different machines, the general consensus seems to be that it's a better idea to write your configurations in a way that allows them to be flexible and easily portable across machines, rather than bundle up a distribution of the Emacs executable itself.

Recently I pass to Emacs org because is really convenient to me to write note there.
So I installed all packages I needed (principally ORG and EVIL) but I didn't understand how to setup everything.
I installed emacs from brew without using cask, I linked it, and I'm sure that I'm using the version that I installed (26.1).
So in my ~/ folder I have a .emacs file in which I set up evil mode, and I have a /.emacs.d/ in which I have a lot of file. The problem is: whatever I wrote in a ~/.emacs.d/init.el seems doesn't effect emacs.
So I said "whatever, I'm going on github and I installed some complete configurations and then I customized them myself". I tried to install these two configurations.
https://github.com/hrs/dotfiles
https://github.com/larstvei/dot-emacs?files=1
But for some reason, after doing exactly what they say on README.org
nothing happens.
In particular the second link, after install and open emacs said I need to have ~/.cask/.cask.el but I don't have it.
Advice?
I have emacs24 and emacs25 on my machine. I want to use spacemacs with emacs24 and keep emacs25...well...as emacs. When I install spacemacs my ~/.emacs and ~/.emacs.d are changed. Both emacs start using spacemacs, which I do not want. Is there a way to have a spacemacs and an emacs at the same time. Tried looking for a solution and came across a solution to keep separate config files. But how to make emacs look for a specific config file. By the way if you still haven't guessed...I'm a noob.
At one level, this is quite easy to do. However, at another, there can be some
complications, depending on what you really want to do.
Emacs supports a command line switch -l to tell emacs where to find the config
file. So, from a very simple perspective, you could just create two wrapper
scripts my-spacemacs.sh and my-plainemacs.sh and inside them have the scripts
call emacs with a specific -l /path/to/config. You can pass $* to pick up other
command line arguments if you want.
The potential problem with this approach is that emacs will still use .emacs.d
to store all sorts of other information, including possibly elpa packages and
this could cause problems. To be safer, it is better to keep things completely
separate.
If you don't need to run both versions at the same time, the easy solution is to
have to separate directories, such as ~/.spacemacs-emacs.d and ~/plain-emacs.d
and then have a sym link called .emacs.d which points to whichever of the
versions you want to run. The two main problems with this approach is that you
need to reset the symbolic link whenever you want to change emacs flavors and
this won't work if you want to run both versions at the same time.
I guess we really need to know about your actual use case - why do you need two
different configurations? Knowing this could help identify a better approach.
As an example, I use org mode and babel to manage my emacs config. I have a
number of different versions and a simple script which I can run to generate
whichever init.el file I want from the different org files. I have a minimal.org
file, which has the most minimal emacs configuration I can bare and I have my
standard init.org which generates my working init.el and then I have an
experimental.org which is used to generate an init.el file which I use for
experimenting with new configurations or packages. It is trivial to switch
configurations, but I never need to run two different configurations at the same
time.
I often like to check out some of the other pre-cooked emacs setups, like
spacemacs, prelude, etc. for these, I just grab the current git version and use
a symbolic link to point .emacs.d at the root fo the git repo I want to
experiment with.
you can also use the following approach:
create a directory ~/spacemacs.
extract/copy the spacemacs .emacs.d into ~/spacemacs (so that it is ~/spacemacs/.emacs.d).
create a desktop link called Spacemacs (or menu entry) and enter the following command:
HOME=$HOME/spacemacs emacs
You can also start spacemacs from the shell with this command.
This way, you can run vanilla emacs and spacemacs simultaneously, each with its own configuration directory and elpa repository. The only disadvantage might be that you need to change a directory level upward to reach your real home directory, not the „fake” one set via the variable.
btw, this is how I run several emacs versions and configurations, as needed for diverse stuff.
The best solution seems to be using chemacs: https://github.com/plexus/chemacs
Can someone help me make sense of list-buffer (aka Ctrlx - Ctrlb) behavior in emacs 25?
The behavior I'm used to seeing is that it opens the buffer list in another Emacs window (virtual Emacs window), splitting out a second window to do so, if necessary. In some versions it hasn't always been very deterministic which other window it used (if I had more than 2 up), but I could at least count on it not using the one the cursor was in.
I recently installed 25.0.50.1 to get around a remote file open bug (worked!), and now it isn't always doing this. Very often it opens the buffer list in the same window my cursor was in. Often it works the way it used to. I can't figure out any rhyme or reason behind which it choses to do.
Can someone enlighten me as to the algorithm it is using now? It makes managing multiple emacs Windows for reference viewing nearly impossible when I can't predict which window gets replaced.
I would guess your primary concern is to have a convenient way to switch buffer, not to understand the emacs' source code, so I would strongly recommend to check helm package out: http://tuhdo.github.io/helm-intro.html
It will take about 10 to 20 minutes to install and follow the tutorial, and it is well worth. I promise.
After installing helm and enabling it, the key sequence for you is Ctrl-x b: Shows open buffers, recently opened files
You will get a power pack of many other tools to work in emacs. I had the same problem with switching buffers, and seemingly 'chaotic' buffer popup. After helm installation, the problem is minimized to invisible because it is so easy to switch to the buffers you want.
Update:
To deal package installation errors and package compatibility:
M-x list-load-path-shadows to see if there is any conflicting packages. And since you may not have many external packages, I suggest backup ~/.emacs.d and have a new empty one. Also, most of the case when install packages, I try to use emacs package manager. Benefits of using package manger:
help check dependencies
avoid to manual download and unpack.
can do batch update of installed packages
Following is a workflow of enabling melpa repo and installing packages
M-x customize-group RET package
# Click or move cursor to and enter: Package Archives
# Insert the melpa repository.
Archive name: melpa
URL or directory name: http://stable.melpa.org/packages/
#Save above settings and then you can use the following to install packages:
M-x list-packages RET
f to filer package names
i to mark for installation
x for execution of installation
u for unmark package at cursor.
# to avoid using load-path repeatedly,
# I have this in my .emacs before any 'require' command:
; Set path recursively to one folder
(let ((default-directory "~/.emacs.d/elpa/"))(normal-top-level-add-subdirs-to-load-path))
I'm pretty new to emacs and I'm currently trying to configure it properly for my needs, but I can't make it load web-mode at all.
So, this is what I've done:
Downloaded web-mode.el from GitHub
Made sure the file is located in the correct directory: ~/.emacs.d/web-mode.el
Used the installation instructions from the official page
My .emacs file now looks like this
Issue:
When I'm trying to edit any of the file types specified in the .emacs file, it only runs the default modes. PHP Abbrev for PHP etc... I'm not receiving any error messages and when I'm running --debug-init it does not give any output.
Emacs version: GNU Emacs 23.1.1 (x86_64-redhat-linux-gnu, GTK+ Version 2.18.9) of 2012-03-01 on sl6.fnal.gov
OS: Scientific Linux
Does anyone know how I can troubleshoot this further, or have solved similar issues?
You should let el-get install it for you. El-get is a package manager for emacs. It can install packages from github, emacswiki, elpa, an url, … http://wikemacs.org/index.php/El-get
It's very handy, you can update scripts easily, it manages dependencies, it lets you discover many stuff, you can easily share your config accross machines, etc.
Emacs 24 has package.el or ELPA by default. One can install it on emacs 23, but my experience isn't conclusive so I'd advise sticking with el-get, which is great.
How to change default installed packages location?
I'd like to build stand-alone emacs distribution. Something that I can put on net folder or a usb stick, unpack on arbitrary system that has emacs itself installed, work with provided settings and doesn't mess with original emacs settings resided on the system. It is like a showcase for what emacs is capable for my buddies.
I've redefined load-path and so on in init.el but failed to customize elpa working locations. I search through emacs self-documenting info system and found no documentation about package system's meta-files location and installed packages path. Obviously I can not leave with default values, and I doesn't know what variables to modify or hooks to setup.
package-user-dir is the variable you want. From the docs:
package-user-dir is a variable defined in `package.el'. Its value is
"~/.emacs.d/elpa"
This variable is potentially risky when used as a file local
variable.
Documentation: Directory containing the user's Emacs Lisp packages.
The directory name should be absolute. Apart from this directory,
Emacs also looks for system-wide packages in `package-directory-list'.
(I found this using M-x apropos-variable and searching for 'package').
