In emacs I have got the tuareg mode enabled in the top and the shell in the bottom without color syntax. How can I have color syntax in the shell?
In order to get here, I installed camllight using this script http://judicael.courant.free.fr/2015/02/20/installationcaml.html
then, I installed melpa
M-x list-packages
to search and to install tuareg. And finally, I edited .emacs with (add to list 'load-path "home/pi/.emacs.d/lisp") where lisp is a directory which contain tuareg.el, camldebug.el, tuareg-site-file-el
emacs window:
The mode that you're looking for is not the one that comes with Tuareg. The guy in the video is using the inferior-ocaml mode that is a part of an old caml-mode that used to be distributed with the OCaml compiler. Unless you really want the exact setup as in the video, I would suggest you use a more modern Tuareg mode together with the OCaml Merlin. Otherwise, you should remove Tuareg and install caml-mode using M-x package-install <RET> caml-mode <RET> (see also the documentation on the Github page of the project for more details).

In Windows 10, Emacs 26.3 with inbuilt org version 9.1.9 is working fine (Packaged binaries). Recently I tried Emacs 27.1. with inbuilt org version 9.3. While loading .org files for first time, I get the message (Shell command succeeded with no output) and org files are not rendered at all. To render it, I have to use M-x org-mode or reload the file in the buffer again. I tried to run without loading .emacs.d folder packages. The issue persists. It means, it has nothing to do with already installed other packages. I also tried with latest org version 9.3.7 and and also tried with emacs -Q. Still the issue persists. Any solutions?
I know I'm very late, but found in Jeffs words:
Evil remaps C-i to evil-jump-forward to emulate Vim’s jump lists feature2, which overwrites the default mapping for the TAB key in Org mode.
To fix the tab key’s functionality in Org mode, sacrifice Evil’s C-i backward jumping by turning it off in your configuration with the evil-want-C-i-jump option.
So to solve, just edit your init.el to look like this:
;; Install Evil and disable C-i to jump forward to restore TAB functionality in Org mode.
(use-package evil
:init (setq evil-want-C-i-jump nil)
:config (evil-mode))

I'm using emacs -nw (Emacs 24.5, Ubuntu 16.04). And I found that the default emacs M-w C-y keys don't work interchangeably with the operating system.
After some research, it seems that the most comprehensive solution is to use simpleclip. EmacsWiki says that
simpleclip
You can use https://github.com/rolandwalker/simpleclip which ALWAYS
works.
But looking into its usage guide above, simpleclip makes use of a set of keys that are completely different from the default M-w C-y or the OS Ctrl-Shift-c, Ctrl-Shift-v for copy-paste
;; Press super-c to copy without affecting the kill ring.
;; Press super-x or super-v to cut or paste.
I don't really want to use super key a lot with my PC keyboards, and don't want to remember (or persuade others to remember) yet another set of copy-paste keys.
For the GUI emacs, I can copy something in emacs and paste it into another terminal without any configuration. Mostly, I don't feel that Emacs is any different from gedit except that the emacs copy-paste keys M-w C-y can be used in addition.
In the terminal mode, most of it breaks down. If I use OS copy (Ctrl-Shift-c), one line in emacs can be copied into two or more lines in a target terminal because the line is too long. contents copied using M-w simply do not paste into other programs, even though I tried to set certain variables following other SO questions, e.g.:
(setq x-select-enable-clipboard t)
I'm not very familiar with elisp. My question:
How can I customize or configure simpleclip so that copy-paste in emacs -nw is exactly the same as copy-paste in the OS?

I recommend you use the xclip package, which you can install from GNU ELPA (i.e. via M-x package-list-packages). It requires installation of the xclip utility under X11 (e.g. via aptitude install xclip) and uses the pbcopy/pbpaste under macOS.
I want to use the command C-c C-x C-l to preview latex code in org-mode. Since the emacs-nox cannot do this, I tried apt-get install emacs24. However, after I have installed the emacs24 with GUI, I get an error like
can't find \`latex'(needed to convert LaTeX fragments to images)
I have installed texlive2016, and I can latex *.tex in shell command.
I added the /paht/to/latex to .emacs, but it don't work well.
Adding the following to my init.el makes it work:
;; Making emacs find latex (so that C-c C-x C-l works on orgmode)
(setenv "PATH" (concat ":/Library/TeX/texbin/" (getenv "PATH")))
(add-to-list 'exec-path "/Library/TeX/texbin/")
It is not a very pretty solution, but it does the job and is very easy to modify and understand.
This solution worked on a Mac running macOS Sierra and Emacs v25.1.
My crystal ball tells me that the problem is that you're not starting the GUI Emacs from a terminal, so it can't inherit your $PATH settings. See for example https://emacs.stackexchange.com/questions/10722/ (that question is within OSX, but the same problem appears in other systems).
Apparently you can set env-vars globally (so that they affect all applications, including those started directly from the GUI) in ~/.pam_environment (that's for GNU/Linux systems). Note that this is only consulted when you login, so you need to logout+login for changes to take effect.
So I've installed ELPA, and did the command M-x package-install RET auctex.
I was prompted with the message that 133 files were compiled and one was skipped.
But I cannot find auctex mode anywhere when trying to initialize it with M-x auctex-mode.
Am I missing something?
AUCTeX is a package that includes multiple TeX and LaTeX modes, but does not define an explicit AUCTeX mode. To invoke a mode explicitly, use M-x TeX-<TAB> or M-x LaTeX-<TAB> to see the possibilities.
Assuming that the package is installed correctly, these tab-completions should resolve.
Various of the modes may be started automatically upon opening files with certain extensions, perhaps like myfile.tex or similar.
I have successfully installed hy-mode from https://github.com/hylang/hy-mode. I now can open a .hy file in emacs and have syntax highlighting, and editing with paredit is a joy.
I however, don't know how to start a REPL. At the bottom of the github readme, it says:
When in hy-mode, you can launch a Hy REPL by launching a Lisp inferior
process
M-x lisp-inferior-process
That function, however, is not defined for me. What else do I need to install or check to be able to use the repl for Hy?
I am currently using:
GNU Emacs 24.3.1.
Have you tried to set inferior-lisp-program to "hy" and then doing M-x run-lisp?
This is the standard way (or maybe just the "way I know about") of having an inferior lisp process.
As of version 1.0.4 of hy-mode, you can start a hy repl buffer in Emacs using M-x run-hy or use the default key binding of C-c C-z.
In any Emacs mode, including hy-mode, you can use M-x describe-mode or the default key binding of C-h m to show key bindings for the current mode.
