Emacs can't find gofmt in go-mode - emacs

I'm trying to use Emacs for golang programming. I downloaded the go-mode package and installed it. My .emacs is:
(require 'go-mode)
When I'm opening *.go files, go-mode enables correctly. But I can't save any *.go files because when I'm trying to save *.go files I'm getting an error in the minibuffer that says
gofmtprogram not found.
Golang installed (version 1.3), gofmt works from terminal.
How can I solve this problem?
Thank you.

On OSX I'm usingthe following in .emacs/init.el
(use-package exec-path-from-shell
:ensure t
:init (exec-path-from-shell-initialize))
to insure that Emacs are using the correct path.

Make sure you have gofmt in your PATH. (echo $PATH) to check, if you can't run gofmt in your shell, it is likely that emacs won't as well.
gofmt on my setup is in $GOBIN/gofmt, but I think it can be as well be in one of the $GOPATH/bin.
If you have it in your path, chances are that you have an emacs configuration that sets the path. Change as needed.
If you installed via a packet manager, chances are that gofmt will be somewhere else. (I think brew puts it in /usr/local/bin)
Small tip when this happen and you really need to save: switch back to text-mode (M-x text-mode).

Changing the initialization location of Emacs

I used to take the Programming languages course on Coursera and for the sake of the course i installed SML-Mode.
Now, I'd want to set up a Clojure environment in Emacs but instead of initializing Emacs from ~/.emacs.d, it initializes from the Users/karthik/Documents/sml-mode/sml-mode-startup
I deleted the sml-mode folder and on Emacs startup it shows me a warning about the files not being present. How I do point Emacs to load Emacs Live from the home folder.
I'm an Emacs newbie.
One easy way to do it, is
save you closure settings in /some/dir/my-closure-settings.el and call emacs as the following (to learn about -q -l , try emacs --help )
$ emacs -q -l /some/dir/my-closure-settings.el
or even placing an alias in bashrc,
$ alias closure-emacs='emacs -q -l /some/dir/my-closure-settings.el'
$ closure-emacs # will start emacs with your closure settings.
As you progress in learning some elisp, you will want to do it in one folder.
Assuming you installed Emacs yourself, and this SML-mode was an independent package, then I would speculated that it may have modified your site-start.el.
See if running emacs --no-site-file makes a difference.
If that's the issue, you can visit the file with:
M-: (find-library site-run-file) RET
You might also check:
C-hv user-emacs-directory RET
when running emacs in various ways:
emacs
emacs --no-site-file
emacs -q
emacs -Q
Unless it's a custom binary, at some point it should tell you "~/.emacs.d/"
Installing SML-mode does not change the place of the main initialization file, which is one of ~/.emacs or ~/.emacs.d/init.el. So look at those files (which ever of the two is present), and if none is present, then just create it and add what you need in it.
BTW, it looks like you're using an old sml-mode package (the newer one doesn't have an sml-mode-startup.el file). So please try and make sure the documentation that pointed you to that mode is updated: nowaday sml-mode should be installed from GNU ELPA, i.e. via M-x package-list or M-x package-install.

Emacs not recognising .emacs.d folder on startup

I'm new to Emacs. I recently got a dot-emacs configuration from GitHub. Cloned the repo in my home directory as .emacs.d
This is for setting up a clojure environment. When i open Emacs and enter
M-x nrepl-jack-in, the minibuf displays 'No Match'
What am I doing incorrectly? Thanks!
It's possible that nREPL isn't being loaded. Add the following to your init.el:
(autoload 'nrepl-jack-in "nrepl" nil t)
You should be able to run it now with M-x nrepl-jack-in.
If the command doesn't work you'll need to do some troubleshooting.
make sure that nREPL is actually installed. You'll need both the Emacs library and the nREPL server.
check for any errors during startup. Launch Emacs from the terminal using the --d flag:
emacs --d
You will get a backtrace if anything goes wrong during the startup.
verify that your init.el is actually being loaded. Add the following code to the end of your init.el and restart Emacs.
(message "---> LOADED")
This will show in your *Messages* buffer if everything is being loaded.
Edit:
Looks like your init.el isn't being loaded. Check your home folder for files called .emacs or .emacs.el, which might be getting loaded instead.
Otherwise it could still be a path issue. Open a terminal and make sure this is the file you expect:
less ~/.emacs.d/init.el

Emacs 24.3 dired+ won't load

I installed dired+ through list-packages (the folder was put in the elpa folder), and put '(add-to-list 'load-path "~/.emacs.d/elpa/")' in my init file (which I created myself), and '(require 'dired+) under. When I open emacs, I get an error telling me there's an error in my init file. If I remove the '(require 'dired+) line, the error stops, but again dired+ doesn't work when I call dired mode. The actual folder that was downloaded when I installed it is 'dired+-20130206.1702'. So I tried '(require dired+-20130206.1702), which again gave me an error on startup.
I'm at my wits end. I've tried everything I can think of, gone through the GNU emacs docs, googled the problem, looked at the answers here at Stack, and no luck. Does anyone have any suggestions? I'm using Windows XP.
It's impossible to say for certain without seeing all the code, but you appear to be quoting your forms for no reason.
i.e., these:
'(add-to-list 'load-path "~/.emacs.d/elpa/")
'(require 'dired+)
should be:
(add-to-list 'load-path "~/.emacs.d/elpa/")
(require 'dired+)
However that should just make them ineffectual, rather than causing errors directly.
Show us the code and the error message.
Edit:
Adding the /dired+/ to the end seemed to fix it ... Although I have no idea why. Any thoughts?
load-path holds a list of directories in which Emacs will look for libraries. It does not automatically descend into sub-directories, so you need to specify all relevant directories for your libraries. Your dired+ library is clearly in the ~/.emacs.d/elpa/dired+/ directory.
For menubarplus, you will similarly need to check to see which directory the library is in.
To be honest, I had thought that the package management in Emacs 24 would take care of this automatically; but as I've not been using it, I'm not certain.
Edit 2:
Yes, I suspect you have some other problem here. I just experimented with installing a library via the package manager (albeit from the default package repository, which doesn't include a dired+ package), and after restarting Emacs load-path contained the path for the new library without any intervention on my part.
I think Phils answered your question wrt loading Dired+ (specify the right directory, the one where you put dired+.el).
Wrt Menu-bar+, the feature name is menu-bar+, not menubarplus and not menu-barplus. So change your (require 'menubarplus) to (require 'menu-bar+).

gdb within emacs on Windows

I'm running Emacs 22.3 in Windows. Earlier today I had gdb working within Emacs just fine. I was installing QT4 and during the installation it asked me to uninstall MSYS which I quickly clicked through not thinking about things. I think I had gdb installed with the MSYS package and Emacs was using that, but I'm not completely sure. Now when I run the following I get an error in the mini-buffer.
M-x gdb
"Searching for program: no such file or directory, gdb"
I tried to add the path "C:\cygwin\bin" to the Emacs load-path with this code but I still get the same error.
(message "Adding cygwin/bin to load path.")
(add-to-list 'load-path "c:/cygwin/bin")
Could someone tell me what I'm doing wrong?
Thanks.
probably adjust your system path to point it where you have gdb installed.
Try using /cygdrv/c/cygwin/bin

How do I byte-compile everything in my .emacs.d directory?

I have decided to check out Emacs, and I liked it very much. Now, I'm using the Emacs Starter Kit, which sort of provides better defaults and some nice customizations to default install of Emacs.
I have customized it a little, added some stuff like yasnippet, color-themes, unbound, and other stuff. I've set up a github repository where I keep all of the customizations so I can access them from multiple places or in case something goes bad and I lose my .emacs.d directory.
All of this is very nice, but there is a problem: Emacs takes about 1-2 seconds to load. AFAIK I can compile individual .el files with M-x byte-compile-file to .elc, and it works. But there are a lot of .el files, and I wonder if there is a way to compile them all with a simple command or something, to speed up the loading of Emacs. My Emacs is not always open, and I open and close it quite frequently, especially after I've set it up as a default editor for edit command in Total Commander to get used to it faster (yeah, windows xp here).
My Emacs version is 22.3. And yes, the default Emacs installation without any customizations fires up instantly.
I am not sure which version is preferred when loading, the .el or compiled .elc one by the way O.o
So, is there an elisp command or Emacs command line switch to make Emacs byte-compile everything in .emacs.d directory?
C-u 0 M-x byte-recompile-directory
will compile all the .el files in the directory and in all subdirectories below.
The C-u 0 part is to make it not ask about every .el file that does not have a .elc counterpart.
To automatically byte compile everything that needs byte compiling each time I start emacs, I put the following after my changes to load-path at the top of my .emacs file:
(byte-recompile-directory (expand-file-name "~/.emacs.d") 0)
Surprisingly, it doesn't add much to my startup time (unless something needs to be compiled).
To speed up my emacs, I first identified the slow parts using profile-dotemacs.el and then replaced them with autoloads.
You can use the --batch flag to recompile from the command line.
To recompile all, do
emacs --batch --eval '(byte-recompile-directory "~/.emacs.d")'
or to recompile a single file as from a Makefile,
emacs --batch --eval '(byte-compile-file "your-elisp-file.el")'
This is swaying a bit from the question, but to solve the problem of loading slowly you can use the new daemon feature in Emacs 23.
"If you have a lot of support packages,
emacs startup can be a bit slow.
However, emacs 23 brings emacs
--daemon, which enables you to start emacs in the background (for example
when you log in). You can instantly
pop up new emacs windows (frames) with
emacsclient. Of course, you could
already have an emacs 'server' in
older versions, but being able to
start it in the background makes this
a much nicer solution"
From http://emacs-fu.blogspot.com/2009/07/emacs-23-is-very-near.html
The command I use is M-x byte-force-recompile RET, it then asks the directory so, for example, I give it ~/.emacs.d/elpa/. It then recompiles everything in there, usually no need to delete .elc files first or mess with it in other ways.
For my using spacemacs, the command is spacemacs/recompile-elpa. The command byte-recompile-directory does not compile any file.
