#+TITLE: bqn-mode

Synopsis

Emacs major mode for BQN programming language.

Extracted from the original [[https://github.com/mlochbaum/BQN][BQN]] repository and independently maintained since approx. 2021.

Before that, bqn-mode was derived and heavily based on the venerable [[https://github.com/lokedhs/gnu-apl-mode][gnu-apl-mode]].

Installing bqn-mode

** From sources

After =git clone= this repository, you can just add the following snippet to you =init.el= file:

#+begin_src lisp (add-to-list 'load-path "~/path/to/bqn-mode") (require 'bqn-mode) #+end_src

** From MELPA

bqn-mode is available on [[https://melpa.org/#/bqn-mode][MELPA]].

Configure your =package-archives= to include MELPA.
- The EmacsWiki has a clean and comprehensive [[https://www.emacswiki.org/emacs/InstallingPackages][tutorial]].
You can now use the typical =M-x list-packages= interface to find and install =bqn-mode=.

Fonts

BQN uses a peculiar set of symbols, not always available on the default fonts of major operating systems. Nonetheless there are many fonts available around the Web. Here are some links:
