-# Common Lisp
-
-## Introduction
-
-### Common Lisp
-
-Common Lisp is the programmable programming language.
-
-Lisp essays by Paul Graham
-<http://www.paulgraham.com/lisp.html>
-
-Standardised in 1994 by ANSI
-
-Common Lisp the Language, 2nd Edition
-<https://www.cs.cmu.edu/Groups/AI/html/cltl/cltl2.html>
-
-Common Lisp Hyperspec
-<http://www.lispworks.com/documentation/HyperSpec/Front/>
-
-<http://cliki.net>
-
-### Common Lisp
-
-Several compilers implement the ANSI standard :
-
-  - SBCL (open-source, x86, amd64, Windows, Linux, OSX, \*BSD)
-    <http://sbcl.org>
-
-  - ABCL (open-source, jvm)
-    <https://abcl.org>
-
-  - Clozure CL (open-source, x86, amd64, Windows, Linux, OSX, FreeBSD)
-    <https://ccl.clozure.com>
-
-  - ECL (open-source, compiles to C)
-    <https://common-lisp.net/project/ecl/main.html>
-
-  - LispWorks (proprietary, x86, amd64, Windows, Linux, OSX, FreeBSD)
-    <http://www.lispworks.com/products/lispworks.html#personal>
-
-  - Allegro CL (proprietary, x86, amd64, sparc, Windows, Linux, OSX,
-    FreeBSD)
-    <https://franz.com/products/allegrocl>
-
-## Installation
-
-### Install SBCL
-
-Ubuntu :
-
-```
-  sudo apt-get install sbcl
-```
-
-MacOS X :
-
-```
-  brew install sbcl
-```
-
-### Install repo
-
-```
-mkdir -p ~/common-lisp/thodg
-cd ~/common-lisp/thodg
-git clone https://github.com/thodg/repo.git
-cd ~/common-lisp
-ln -s thodg/repo/repo.manifest
-```
-
-### Configure SBCL
-
-Edit `~/.sbclrc`
-
-```
-  ;; ASDF
-  (require :asdf)
-
-  ;; repo
-  (load "~/common-lisp/thodg/repo/repo")
-  (repo:boot)
-```
-
-### Launch SBCL
-
-    $ sbcl
-    This is SBCL 1.5.3, an implementation of ANSI Common Lisp.
-    More information about SBCL is available at <http://www.sbcl.org/>.
-
-    SBCL is free software, provided as is, with absolutely no warranty.
-    It is mostly in the public domain; some portions are provided under
-    BSD-style licenses.  See the CREDITS and COPYING files in the
-    distribution for more information.
-
-    * _
-
-### Install Slime
-
-    * (repo:install :slime)
-
-    $ /usr/bin/git -C /home/dx/common-lisp/slime clone https://github.com/slime/slime.git
-    Cloning into 'slime'...
-
-### Configure emacs
-
-Edit ` ~/.emacs  `
-
-```
-  ;; Common Lisp
-  (add-to-list 'load-path "~/common-lisp/slime/slime/")
-  (require 'slime-autoloads)
-  (add-to-list 'slime-contribs 'slime-fancy)
-  (setq inferior-lisp-program
-        "sbcl")
-  (setq slime-net-coding-system
-        'utf-8-unix)
-```
-
-## Demo
-
-### Launch emacs and slime
-
-    $ emacs
-
-    M-x slime
-
-    CL-USER> _
-
-### The REPL
-
-REPL : `read`, `eval`, `print
-loop`
-
-```
-  (loop
-    ;; setup REPL vars
-    ;; handle errors, interactive debugger
-    (print
-      (eval
-        (read)))
-    (force-output)) ;; flush output buffers
-```
-
-### Symbols
-
-A symbol compares faster than a string (pointers comparison).
-
-To get a symbol through `eval` we have to quote it, with a single
-quote prefix.
-
-```
-  ;; SLIME
-  CL-USER> 'hello-world
-  
-  HELLO WORLD
-  CL-USER> (quote hello-world)     ; equivalent sans syntaxe
-  
-  HELLO WORLD
-```
-
-<http://www.gigamonkeys.com/book/programming-in-the-large-packages-and-symbols.html>
-
-### Symbols
-
-If the symbol is not quoted then we end up in the interactive debugger :
-
-```
-  ;; SLIME
-  CL-USER> hello-world
-
-  The variable HELLO-WORLD is unbound.
-     [Condition of type UNBOUND-VARIABLE]
-
-  Restarts:
-   0: [CONTINUE] Retry using HELLO-WORLD.
-   1: [USE-VALUE] Use specified value.
-   2: [STORE-VALUE] Set specified value and use it.
-   3: [RETRY] Retry SLIME REPL evaluation request.
-   4: [*ABORT] Return to SLIME's top level.
-
-  Backtrace:
-    0: (SB-INT:SIMPLE-EVAL-IN-LEXENV HELLO-WORLD #<NULL-LEXENV>)
-    1: (EVAL HELLO-WORLD)
-   --more--
-
-  4
-  ; Evaluation aborted on #<UNBOUND-VARIABLE HELLO-WORLD {1004AF3523}>.
-  CL-USER> _
-```
-
-### Functions
-
-`defun` defines a function.
-
-If the first element of a list
-(between parentheses) is a function or a symbol naming a function then
-the list is treated as a function call.
-
-```
-  ;; SLIME
-  CL-USER> (defun hello-world ()
-             (format t "Hello world !"))
-  HELLO-WORLD
-  CL-USER> (hello-world)
-  Hello world !
-  NIL
-  CL-USER> _
-```
-
-### Lambda
-
-`lambda` introduces an anonymous function. We can affect an
-anonymous function to a symbol, not unlike `defun`.
-
-```
-  ;; SLIME
-  CL-USER> (setf (symbol-function 'hello-world)
-                 (lambda ()
-                   (format t "Hello world !")))
-
-  CL-USER> (hello-world)
-  Hello world !
-  NIL
-  CL-USER> _
-```
-
-### Higher order functions
-
-A function is a value like others and can be passed to another function.
-
-We call these functions higher order.
-
-```
-  ;; SLIME
-  CL-USER> (mapcar (lambda (x) (* x x)) '(1 2 3 4 5))
-  (1 4 9 16 25)
-  CL-USER> (reduce #'+ '(1 2 3 4 5))
-  15
-  CL-USER> (reduce (function +) '(1 2 3 4 5)) ; equivalent to above
-  15
-  CL-USER> (reduce '+ '(1 2 3 4 5)) ; not equivalent will resolve
-                                    ; function at run-time
-  15
-  CL-USER> _
-```
-
-### Macros
-
-  - parameters are not evaluated -> DSL and
-    meta-programming
-
-  - generate code which is in turn evaluated
-
-  - backquote and comma to quote only parts

-             `(format nil "Hello ~A !"
-                (string-capitalize ',arg)))

-
-### Quasiquotation
-
-To quote entirely :
-  `'(a b c)`
-or
-  `(quote (a b c))`
-->
-  `(a b c)`
-
-To quote partially :
-  `` `(a b ,c)``
-or
-  `(list 'a 'b c)`
-->
-  `(a b 123)` if `c = 123`
-
-Backquote stops evaluation and comma reactivates it locally.
-
-```
-  ;; SLIME
-  CL-USER> (let ((c 123))
-             `(a b ,c))
-  (A B 123)

-CL-USER> _
-\end{verbatim}
-\end{frame}
-
-\begin{frame}[fragile]
-  \frametitle{The REPL}
-  REPL : {\tt read}, {\tt eval}, {\tt print loop}
-\begin{verbatim}
-  (loop
-    ;; setup REPL vars
-    ;; handle errors, interactive debugger
-    (print
-      (eval
-        (read)))
-    (force-output)) ;; flush output buffers
-\end{verbatim}
-\end{frame}
-
-\begin{frame}[fragile]
-  \frametitle{Symbols}
-  A symbol compares faster than a string
-  (pointers comparison).
-  To get a symbol through {\tt eval} we have to quote it, with a single quote prefix.
-\begin{verbatim}
-  ;; SLIME
-  CL-USER> 'hello-world
-  
-  HELLO WORLD
-  CL-USER> (quote hello-world)     ; equivalent sans syntaxe
-  
-  HELLO WORLD
-\end{verbatim}
-  \vspace{1em}
-  \url{http://www.gigamonkeys.com/book/programming-in-the-large-packages-and-symbols.html}
-\end{frame}
-
-\begin{frame}[fragile]
-  \frametitle{Symbols}
-  If the symbol is not quoted then we end up in the interactive debugger :
-\begin{verbatim}
-  ;; SLIME
-  CL-USER> hello-world
-  
-  The variable HELLO-WORLD is unbound.
-     [Condition of type UNBOUND-VARIABLE]
-  
-  Restarts:
-   0: [CONTINUE] Retry using HELLO-WORLD.
-   1: [USE-VALUE] Use specified value.
-   2: [STORE-VALUE] Set specified value and use it.
-   3: [RETRY] Retry SLIME REPL evaluation request.
-   4: [*ABORT] Return to SLIME's top level.
-  
-  Backtrace:
-    0: (SB-INT:SIMPLE-EVAL-IN-LEXENV HELLO-WORLD #<NULL-LEXENV>)
-    1: (EVAL HELLO-WORLD)
-   --more--
-  
-  4
-  ; Evaluation aborted on #<UNBOUND-VARIABLE HELLO-WORLD {1004AF3523}>.
-  CL-USER> _
-\end{verbatim}
-\end{frame}
-
-\begin{frame}[fragile]
-  \frametitle{Functions}
-  {\tt defun} defines a function.
-  If the first element of a list (between parentheses) is a function or a symbol naming a function then the list is treated as a function call.
-\begin{verbatim}
-  ;; SLIME
-  CL-USER> (defun hello-world ()
-             (format t "Hello world !"))
-  HELLO-WORLD
-  CL-USER> (hello-world)
-  Hello world !
-  NIL
-  CL-USER> _
-\end{verbatim}
-\end{frame}
-
-\begin{frame}[fragile]
-  \frametitle{Lambda}
-  {\tt lambda} introduces an anonymous function. We can affect an anonymous function to a symbol, not unlike {\tt defun}.
-\begin{verbatim}
-  ;; SLIME
-  CL-USER> (setf (symbol-function 'hello-world)
-                 (lambda ()
-                   (format t "Hello world !")))
-  
-  CL-USER> (hello-world)
-  Hello world !
-  NIL
-  CL-USER> _
-\end{verbatim}
-\end{frame}
-
-\begin{frame}[fragile]
-  \frametitle{Higher order functions}
-  A function is a value like others and can be passed to another function. We call these functions higher order.
-\begin{verbatim}
-  ;; SLIME
-  CL-USER> (mapcar (lambda (x) (* x x)) '(1 2 3 4 5))
-  (1 4 9 16 25)
-  CL-USER> (reduce #'+ '(1 2 3 4 5))
-  15
-  CL-USER> (reduce (function +) '(1 2 3 4 5))    ; equivalent to above
-  15
-  CL-USER> (reduce '+ '(1 2 3 4 5))    ; not equivalent will resolve function at run-time
-  15
-  CL-USER> _
-\end{verbatim}
-\end{frame}
-
-\begin{frame}[fragile]
-  \frametitle{Macros}
-  \begin{itemize}
-    \item parameters are not evaluated $\Rightarrow$ DSL and meta-programming
-    \item generate code which is in turn evaluated
-    \item backquote and comma to quote only parts
-  \end{itemize}
-\begin{verbatim}
-  ;; SLIME
-  CL-USER> (defmacro hello (arg)
-             `(format nil "Hello ~A !"
-                (string-capitalize ',arg)))
-  HELLO
-  CL-USER> (hello world)
-  "Hello World !"
-  CL-USER> (hello pony)
-  "Hello Pony !"
-  CL-USER> _
-\end{verbatim}
-  \vspace{1em}

-  \url{http://lib.store.yahoo.net/lib/paulgraham/onlisp.pdf}
-\end{frame}
-
-\begin{frame}[fragile]
-  \frametitle{Quasiquotation}
-  \begin{itemize}
-  \item To quote entirely : {\tt '(a b c)} or {\tt (quote (a b c))} \\
-    $\Rightarrow$ {\tt (a b c)}
-  \item To quote partially : {\tt `(a b ,c)} or {\tt (list 'a 'b c)} \\
-    $\Rightarrow$ {\tt (a b 123)} if {\tt c = 123}
-  \end{itemize}
-  Backquote stops evaluation and comma reactivates it locally.
-\begin{verbatim}
-  ;; SLIME
-  CL-USER> (let ((c 123))
-             `(a b ,c))
-  (A B 123)

+
+### Functions
+
+`defun` defines a function.
+
+If the first element of a list
+(between parentheses) is a function or a symbol naming a function then
+the list is treated as a function call.
+
+```
+  ;; SLIME
+  CL-USER> (defun hello-world ()
+             (format t "Hello world !"))
+  HELLO-WORLD
+  CL-USER> (hello-world)
+  Hello world !
+  NIL
+  CL-USER> _
+```
+
+### Lambda
+
+`lambda` introduces an anonymous function. We can affect an
+anonymous function to a symbol, not unlike `defun`.
+
+```
+  ;; SLIME
+  CL-USER> (setf (symbol-function 'hello-world)
+                 (lambda ()
+                   (format t "Hello world !")))
+
+  CL-USER> (hello-world)
+  Hello world !
+  NIL
+  CL-USER> _
+```
+
+### Higher order functions
+
+A function is a value like others and can be passed to another function.
+
+We call these functions higher order.
+
+```
+  ;; SLIME
+  CL-USER> (mapcar (lambda (x) (* x x)) '(1 2 3 4 5))
+  (1 4 9 16 25)
+  CL-USER> (reduce #'+ '(1 2 3 4 5))
+  15
+  CL-USER> (reduce (function +) '(1 2 3 4 5)) ; equivalent to above
+  15
+  CL-USER> (reduce '+ '(1 2 3 4 5)) ; not equivalent will resolve
+                                    ; function at run-time
+  15
+  CL-USER> _
+```
+
+### Macros
+
+  - parameters are not evaluated -> DSL and
+    meta-programming
+
+  - generate code which is in turn evaluated
+
+  - backquote and comma to quote only parts
+
+
+```
+  ;; SLIME
+  CL-USER> (defmacro hello (arg)
+             `(format nil "Hello ~A !"
+                (string-capitalize ',arg)))
+  HELLO
+  CL-USER> (hello world)
+  "Hello World !"
+  CL-USER> (hello pony)
+  "Hello Pony !"
+  CL-USER> _
+```
+
+On Lisp, Paul Graham
+<http://lib.store.yahoo.net/lib/paulgraham/onlisp.pdf>
+
+### Quasiquotation
+
+To quote entirely :
+  `'(a b c)`
+or
+  `(quote (a b c))`
+->
+  `(a b c)`
+
+To quote partially :
+  `` `(a b ,c)``
+or
+  `(list 'a 'b c)`
+->
+  `(a b 123)` if `c = 123`
+
+Backquote stops evaluation and comma reactivates it locally.
+
+```
+  ;; SLIME
+  CL-USER> (let ((c 123))
+             `(a b ,c))
+  (A B 123)

+\begin{frame}[fragile]

+CL-USER> _
+\end{verbatim}

+\begin{frame}[fragile]
+  \frametitle{The REPL}
+  REPL : {\tt read}, {\tt eval}, {\tt print loop}
+\begin{verbatim}
+  (loop
+    ;; setup REPL vars
+    ;; handle errors, interactive debugger
+    (print
+      (eval
+        (read)))
+    (force-output)) ;; flush output buffers
+\end{verbatim}
+\end{frame}
+
+\begin{frame}[fragile]
+  \frametitle{Symbols}
+  A symbol compares faster than a string
+  (pointers comparison).
+  To get a symbol through {\tt eval} we have to quote it, with a single quote prefix.
+\begin{verbatim}
+  ;; SLIME
+  CL-USER> 'hello-world
+  
+  HELLO WORLD
+  CL-USER> (quote hello-world)     ; equivalent sans syntaxe
+  
+  HELLO WORLD
+\end{verbatim}

+  \url{http://www.gigamonkeys.com/book/programming-in-the-large-packages-and-symbols.html}
+\end{frame}
+
+\begin{frame}[fragile]
+  \frametitle{Symbols}
+  If the symbol is not quoted then we end up in the interactive debugger :
+\begin{verbatim}
+  ;; SLIME
+  CL-USER> hello-world
+  
+  The variable HELLO-WORLD is unbound.
+     [Condition of type UNBOUND-VARIABLE]
+  
+  Restarts:
+   0: [CONTINUE] Retry using HELLO-WORLD.
+   1: [USE-VALUE] Use specified value.
+   2: [STORE-VALUE] Set specified value and use it.
+   3: [RETRY] Retry SLIME REPL evaluation request.
+   4: [*ABORT] Return to SLIME's top level.
+  
+  Backtrace:
+    0: (SB-INT:SIMPLE-EVAL-IN-LEXENV HELLO-WORLD #<NULL-LEXENV>)

+  ; Evaluation aborted on #<UNBOUND-VARIABLE HELLO-WORLD {1004AF3523}>.

+\end{verbatim}
+\end{frame}
+
+\begin{frame}[fragile]
+  \frametitle{Functions}
+  {\tt defun} defines a function.
+  If the first element of a list (between parentheses) is a function or a symbol naming a function then the list is treated as a function call.
+\begin{verbatim}
+  ;; SLIME
+  CL-USER> (defun hello-world ()
+             (format t "Hello world !"))
+  HELLO-WORLD
+  CL-USER> (hello-world)
+  Hello world !
+  NIL
+  CL-USER> _
+\end{verbatim}
+\end{frame}
+
+\begin{frame}[fragile]
+  \frametitle{Lambda}
+  {\tt lambda} introduces an anonymous function. We can affect an anonymous function to a symbol, not unlike {\tt defun}.
+\begin{verbatim}
+  ;; SLIME
+  CL-USER> (setf (symbol-function 'hello-world)
+                 (lambda ()
+                   (format t "Hello world !")))
+  
+  CL-USER> (hello-world)
+  Hello world !
+  NIL
+  CL-USER> _
+\end{verbatim}
+\end{frame}
+
+\begin{frame}[fragile]
+  \frametitle{Higher order functions}
+  A function is a value like others and can be passed to another function. We call these functions higher order.
+\begin{verbatim}
+  ;; SLIME
+  CL-USER> (mapcar (lambda (x) (* x x)) '(1 2 3 4 5))
+  (1 4 9 16 25)
+  CL-USER> (reduce #'+ '(1 2 3 4 5))
+  15
+  CL-USER> (reduce (function +) '(1 2 3 4 5))    ; equivalent to above
+  15
+  CL-USER> (reduce '+ '(1 2 3 4 5))    ; not equivalent will resolve function at run-time
+  15
+  CL-USER> _
+\end{verbatim}
+\end{frame}
+
+\begin{frame}[fragile]
+  \frametitle{Macros}
+  \begin{itemize}
+    \item parameters are not evaluated $\Rightarrow$ DSL and meta-programming
+    \item generate code which is in turn evaluated
+    \item backquote and comma to quote only parts
+  \end{itemize}
+\begin{verbatim}

+                (string-capitalize ',arg)))
+  HELLO
+  CL-USER> (hello world)
+  "Hello World !"
+  CL-USER> (hello pony)
+  "Hello Pony !"
+  CL-USER> _
+\end{verbatim}

+\begin{frame}[fragile]
+  \frametitle{Quasiquotation}
+  \begin{itemize}
+  \item To quote entirely : {\tt '(a b c)} or {\tt (quote (a b c))} \\

+  \item To quote partially : {\tt `(a b ,c)} or {\tt (list 'a 'b c)} \\
+    $\Rightarrow$ {\tt (a b 123)} if {\tt c = 123}

+  Backquote stops evaluation and comma reactivates it locally.
