~prettify-symbols-mode~ is also a nifty feature of Emacs, and it is
built-in! With that, I can replace strings of my choice by another
character of my choice!
character of my choice! First, let’s declare the general symbols that
will be used everywhere.
#+begin_src emacs-lisp
(dolist (symbol '(("lambda" . 955)
("mapc" . 8614)))
(add-to-list 'prettify-symbols-alist symbol))
(defun prog-mode-set-symbols-alist ()
(setq prettify-symbols-alist '(("lambda" . ?λ)
("return" . ?⮐)
("null" . ?∅)
("NULL" . ?∅)
("for" . ?∀)
("in" . ?∈)
("and" . ?∧)
("&&" . ?∧)
("or" . ?∨)
("||" . ?∨)
("xor" . ?⊻)))
(prettify-symbols-mode 1))
(add-hook 'prog-mode-hook #'prog-mode-set-symbols-alist)
#+end_src
Let’s enable this mode for any programming mode:
We can now take care of the language-specific symbols. First, let’s
declare some symbols for the Lisp languages.
#+begin_src emacs-lisp
(add-hook 'emacs-lisp-mode-hook #'prettify-symbols-mode)
(setq-default lisp-prettify-symbols-alist '(("lambda" . ?λ)
("mapc" . ?↦)
("and" . ?∧)
("or" . ?∨)
("xor" . ?⊻)
("defun" . ?𝑓)
("defvar" . ?𝑣)
("defcustom" . ?𝑐)
("defconst" . ?𝐶)
("not" . ?!)
("pi" . ?π)))
(defun lisp-mode-prettify ()
(setq prettify-symbols-alist lisp-prettify-symbols-alist)
(prettify-symbols-mode -1)
(prettify-symbols-mode 1))
(dolist (lang '(emacs-lisp lisp common-lisp scheme))
(add-hook (intern (format "%S-mode-hook" lang))
#'lisp-mode-prettify))
#+end_src
Let’s declare also some for Rust:
#+begin_src emacs-lisp
(defun rust-mode-pretty-symbols ()
(push '("fn" . ?𝑓) prettify-symbols-alist)
(push '("struct" . ?Λ) prettify-symbols-alist)
(prettify-symbols-mode -1)
(prettify-symbols-mode 1))
(add-hook 'rustic-mode-hook #'rust-mode-pretty-symbols)
#+end_src
And some for C and C++.
#+begin_src emacs-lisp
(defun c-cpp-mode-pretty-symbols ()
(push '("int" . ?ℤ) prettify-symbols-alist)
(push '("float" . ?ℝ) prettify-symbols-alist)
(push '("#include" . ?⭳) prettify-symbols-alist)
(push '("struct" . ?Λ) prettify-symbols-alist)
(prettify-symbols-mode -1)
(prettify-symbols-mode 1))
(add-hook 'c-mode-hook #'c-cpp-mode-pretty-symbols)
(add-hook 'c++-mode-hook #'c-cpp-mode-pretty-symbols)
#+end_src
#+begin_src emacs-lisp
(defun)
#+end_src
Finally, similar to how ~org-appear~ behaves, let’s show the real string
of our symbols when the cursor is on it.
#+begin_src emacs-lisp
(setq prettify-symbols-unprettify-at-point t)
#+end_src
