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.

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).
I have emacs 24.5.1 on windows with slime installed. I am using sbcl for lisp. When I open up slime, it works, but whenever I try to use comma to invoke a command, it just enters a comma. I can't get to the slime command menu. Is there any other way to get to the command menu besides comma?
Found the solution.
When going to the slime git website, they said you should include this in your initialization file
(setq slime-contribs '(slime-fancy))
It works after adding that to init.el (equivalent of .emacs)
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.
Is it expected that C-M-% and ESC C-% do not run the command query-replace-regexp when running emacs in a terminal window (for example, emacs -nw)?
According to describe-function the binding exists, but emacs runs query-replace instead (which has the binding M-%). This has happened on several machines I've tried it on, and does not happen when I run emacs in a window.
The problem is that C-% simply can't be typed in a terminal. The only control sequences available are those that corresponds to ascii-code 0-31, mainly C-letter.
I have created a new shortcut in my .emacs file.
(global-set-key "\M-q" 'query-replace-regexp)
Control-Alt-Shift-% all together works on Windows and Fedora Linux. Does your keyboard have all those keys?
What are some REPLs for Emacs Lisp?
Is there only one that is within Emacs?
Are there some that run inside terminal outside Emacs?
Based on this question: REPL on console emacs, you can use M-x ielm (inferior emacs lisp mode).
There is a (work in progress) REPL for Emacs for use from the command line. It currently supports basic command line editing and history.
The code is hosted on Github.
There is this project on Gitlab. The REPL can run on a termninal or on Emacs' minibuffer. Even if you run it in "no-window-system" mode (with -nw).
