This package provides basic interaction with a Clojure subprocess (REPL).
It's based on ideas from the popular inferior-lisp
package.
inf-clojure
has two components - a nice Clojure REPL with
auto-completion and a minor mode (inf-clojure-minor-mode
), which
extends clojure-mode
with commands to evaluate forms directly in the
REPL.
For a more powerful/full-featured solution see CIDER.
Available on all major package.el
community maintained repos -
MELPA Stable and MELPA repos.
MELPA Stable is recommended as it has the latest stable version. MELPA has a development snapshot for users who don't mind breakage but don't want to run from a git checkout.
You can install inf-clojure
using the following command:
M-x package-install [RET] inf-clojure [RET]
or if you'd rather keep it in your dotfiles:
(unless (package-installed-p 'inf-clojure)
(package-refresh-contents)
(package-install 'inf-clojure))
If the installation doesn't work try refreshing the package list:
M-x package-refresh-contents
Add the following to your Emacs config to enable
inf-clojure-minor-mode
for Clojure source buffers:
(add-hook 'clojure-mode-hook #'inf-clojure-minor-mode)
Don't enable inf-clojure-minor-mode
and cider-mode
at the same
time. They have overlapping functionality and keybindings and the
result will be nothing short of havoc.
M-x inf-clojure
or C-c C-z
within a Clojure source file.
inf-clojure-program
is a custom variable that defines a program to run
or the tcp socket to connect to when starting inf-clojure
. By default
this variable is set to lein repl
, which will start a REPL via Leiningen.
However, it is possible to use a cons pair like ("localhost" . 5555)
to
connect to a socket REPL like the one provided with planck,
which can be started from the command line with planck -n 5555
.
Use C-u C-c C-z
to start a REPL with a different command/cons pair than
the default specified in inf-clojure-program
.
eldoc-mode
is supported in Clojure source buffers and *inferior-clojure*
buffers which are running a Clojure REPL.
When ElDoc is enabled and there is an active REPL, it will show the argument list of the function call you are currently editing in the echo area.
You can activate ElDoc with M-x eldoc-mode
or by adding the
following to you Emacs config:
(add-hook 'clojure-mode-hook #'eldoc-mode)
(add-hook 'inf-clojure-mode-hook #'eldoc-mode)
ElDoc currently doesn't work with ClojureScript buffers and REPL's. You can leave it enabled, it just won't show anything in the echo area.
In Windows, the REPL is not returning anything. For example, type (+ 1 1)
and press ENTER
, the cursor just drops to a new line and
nothing is shown.
The explanation of this problem and solution can be found here.
The solution is to create a file named .jline.rc
in your $HOME
directory and add this line to that file:
jline.terminal=unsupported
