+1. Introduction
+===============
+The main tutorial for eev starts by explaining the syntax of Emacs
+Lisp - \"Elisp\" from here onwards - using a simple example. To evaluate
+this sexp
+ (+ (* 2 3) (* 4 5))
+Emacs evaluates first its subexpressions, (* 2 3) and (* 4 5), and
+then it calls `+' with the results - i.e., it runs (+ 6 20). Try:
-Preparation:
+ 2
+ 3
+ (* 2 3)
+ 4
+ 5
+ (* 4 5)
+ (+ (* 2 3) (* 4 5))
+ (list (* 2 3) (* 4 5))
- (eepitch-shell)
- (eepitch-kill)
- (eepitch-shell)
-cd
-wget -nc https://tannerlectures.utah.edu/_documents/a-to-z/c/Coetzee99.pdf
+In last sexp the function `list' receives two numbers, 6 and 20, but
+returns a list, (6 20), not a number - and this is an introduction to
+the idea that Elisp functions can receive all kinds of Elips objects
+and return all kinds of Elisp objects.

+2. Lists and conses
+===================
+Lists are implemented using \"cons\"es. For details and lots of great
+diagrams see these two articles in the Wikipedia:
+ https://en.wikipedia.org/wiki/Cons
+ https://en.wikipedia.org/wiki/Cons#Lists
+ https://en.wikipedia.org/wiki/Cons#Trees
+ https://en.wikipedia.org/wiki/S-expression
+The last one explains in detail what are \"sexp\"s.
+The function `cons' \"constructs\" a bigger list by prepending an
+element to it:
+ (list 22 33)
+ (cons 11 (list 22 33))
+ (list 11 22 33)
-;; «find-creating-links-intro» (to ".find-creating-links-intro")
-;; Skel: (find-intro-links "creating-links")
+The functions `car' and `cdr' both receive a list and return the
+components of its first cons. The `car' of a list is its first
+element, and the `cdr' of the list is the \"rest\" of the list. Try:
-(defun find-creating-links-intro (&rest pos-spec-list) (interactive)
- (let ((ee-buffer-name "*(find-creating-links-intro)*"))
- (apply 'find-eintro "\
+ (list 11 22 33)
+ (cons 11 (list 22 33))
+ (car (cons 11 (list 22 33)))
+ (cdr (cons 11 (list 22 33)))
+ (car (list 11 22 33))
+ (cdr (list 11 22 33))
+ (cons (car (list 11 22 33)) (cdr (list 11 22 33)))

+3. `quote'
+==========
+Not all functions evaluate their arguments. For example, `quote'
+expects a single argument and returns it unchanged, without evaluating
+it. Try:
+ (* 2 3)
+ (+ (* 2 3) (* 4 5))
+ (quote (* 2 3))
+ (quote (+ (* 2 3) (* 4 5)))
+Elisp has an abbreviation for `quote' - a single \"'\". Try:
-1. Basic keys (eev)
+ (quote (* 2 3))
+ '(* 2 3)
+
+ (quote '(* 2 3))
+ (quote (quote (* 2 3)))
+
+Elisp has several other functions besides `quote' that do not evaluate
+their arguments. These functions are called \"special forms\" and we
+will see more about them in section 5, 6, 8, and 9.
+
+ (find-elnode \"Special Forms\")
+
+
+
+
+4. Symbols
+==========
+Note that symbols and strings are different:
+
+ (quote *)
+ '*
+ \"*\"
+ (symbol-name (quote *))
+ (symbol-name '*)
+
+Numbers and strings \"evaluate to themselves\". Try:
+
+ 22
+ \"22\"
+ (+ 22 33)
+ (concat \"22\" \"33\")
+
+If you need more evidence that 22 and \"22\" are different run the sexps
+below - they give errors! Numbers can be added but not concatened, and
+strings can be concatenated but not added.
+
+ (+ \"22\" \"33\")
+ (concat 22 33)
+
+
+
+
+5. Variables
+============
+When we evaluate a list like (* 2 3) the symbol in the beginning of
+the list, `*', is interpreted as the name of a function... but when we
+evaluate a symbol by itself it is interpreted as the name of a
+variable, and it returns the value of that variable. Try:
+
+ (set 'a 2)
+ a
+ (* 10 a)
+
+ (set 'a 3)
+ a
+ (* 10 a)
+
+We will often write examples like the one above more compactly, like
+this:
+
+ (set 'a 2)
+ (set 'a 3)
+ a
+ (* 10 a)
+
+If you execute lines 1, 3, and 4 in it you get one behavior, and if
+you execute lines 2, 3, and 4 you get the other one.
+
+Again: note that evaluating the symbol `a' returns the value of a \"as
+a variable\".
+
+The function `setq' works like `set' but it doesn't expect us to quote
+explicitly its first argument. Try:
+
+ (set 'a 2)
+ (setq a 2)
+ (set 'a (* 2 3))
+ (setq a (* 2 3))
+ a
+ (* 10 a)
+
+`setq' is a special form - it doesn't evaluate its first argument but
+evaluates the second one. See:
+
+ (find-elnode \"Setting Variables\" \"Special Form: setq\")
+
+
+
+
+6. Defining functions
+=====================
+Each symbol has a value \"as a variable\" and a value \"as a function\",
+and these two values are independent from one another. We can define
+functions with `defun'. Try:
+
+ (defun foo (a) (* 10 a))
+ (defun foo (a) (* 100 a))
+ (foo 2)
+ (foo 3)
+
+ (setq foo 2)
+ (setq foo 3)
+ (foo foo)
+
+ foo
+ (symbol-value 'foo)
+ (symbol-function 'foo)
+
+Function definitions are stored as lists starting with the symbol
+`lambda' (\"lambda expressions\"). If you are a beginner you should
+treat the details of this as a curiosity - but try the example below:
+
+ (defun foo (a) (* 10 a))
+ (defun foo (a) (* 100 a))
+ (fset 'foo (lambda (a) (* 10 a))
+ (fset 'foo (lambda (a) (* 100 a))
+
+ (symbol-function 'foo)
+ (foo foo)
+
+For more information, see:
+
+ (find-elnode \"Lambda Expressions\")
+ (find-elnode \"Defining Functions\" \"defun name args\")
+ (find-elnode \"Function Names\")
+ (find-elnode \"Symbol Components\")
+ (find-elnode \"Function Cells\")
+ (find-elnode \"Function Cells\" \"symbol-function symbol\")
+ (find-elnode \"Function Cells\" \"fset symbol definition\")
+
+Not all functions are represented as lambda expressions. The functions
+of Emacs that are implemented in C are represented as \"subr\"s, that
+are one of the kinds of objects that I said that I wouldn't discuss in
+this introduction. See:
+
+ (symbol-function '+)
+ (find-elnode \"Programming Types\" \"Primitive Function Type\")
+ (find-elnode \"Primitive Function Type\" \"subrs\")
+
+Also, functions can be byte-compiled, and they can expect and
+receive any number of arguments. See:
+
+ (find-eval-intro \"10.1. Byte-compiled functions\")
+ (find-elnode \"Defining Functions\" \"defun bar (a &optional b &rest c)\")
+
+
+
+
+7. `read' and `eval'
+====================
+We've been evaluating all sexps with `M-e'... but try:
+
+ '(* 2 3)
+ (eval '(* 2 3))
+
+ (setq a '(* 2 3))
+ (setq a '(* 4 5))
+ a
+ (eval a)
+
+ \"(* 2 3)\"
+ (read \"(* 2 3)\")
+ (eval (read \"(* 2 3)\"))
+
+It turns out the `M-e' first extracts a sexp from the current buffer
+as a string, then `read' converts that string to a Lisp object -
+usually a list or symbol -, and `eval' evaluates that list or symbol.
+There is a also a function `prin1-to-string' that does the opposite of
+`read', as in the diagram below:
+
+ read
+ \"(* 2 3)\" -----------------> (* 2 3)
+ <----------------- |
+ prin1-to-string |
+ |
+ v
+ 6
+
+Try:
+
+ (* 2 3)
+ '(* 2 3)
+ (prin1-to-string '(* 2 3))
+
+So: programs and functions can be represented as lists, and also as
+strings that be converted into lists by `read'; they can be inspected,
+edited and modified on-the-fly; and we can write Lisp code that
+generates and evaluates more Lisp code. Eev does this in a handful of
+situations - for example:
+
+ (find-eev-quick-intro \"find-code-c-d\")
+ (find-here-links-intro \"4. `find-here-links-3'\")
+ (find-eev-quick-intro \"4.2. `find-ekey-links' and friends\")
+
+The idea that programs are lists is far more powerful than it
+looks at first sight. See, for example:
+
+ https://sep.yimg.com/ty/cdn/paulgraham/bbnexcerpts.txt
+ http://www.paulgraham.com/diff.html
+ http://www.paulgraham.com/lisp.html
+ (find-elnode \"Simple Macro\")
+
+Some functions in eev expect code that is meant to be `eval'-ed
+later. For example:
+
+ (find-multiwindow-intro \"(find-wset\" \"13o_2o_o\")
+ (find-wset \"13o_2o_o\" '(find-ebuffer \"B\") '(find-ebuffer \"C\"))
+
+The functions in the `code-c-d' family produce code that is first
+`read' and then `eval'-ed. See:
+
+ (find-eev-quick-intro \"9.1. `code-c-d'\")
+ (find-code-c-d \"CODE\" \"/DIR/\" :info \"INFO\")
+
+
+
+
+
+8. `let' and `let*'
===================
-(...)
-The beginner's way of creating \"hyperlinks to here\" is with:
- M-h M-3 - (find-here-links-intro \"4. `find-here-links-3'\")
- M-h M-1 - (find-here-links-intro \"5. `find-here-links-1'\")
- M-h M-w - (find-here-links-intro \"6. Copying the hyperlink\" \"M-h M-w\")
+ (find-elnode \"Local Variables\" \"Special Form: let \")
+ (find-elnode \"Local Variables\" \"Special Form: let* \")
-" pos-spec-list)))
+9. More on strings
+==================
+Strings in Elisp can span several lines and can contain many
+kinds of backslashed \"escape sequences\", like \"\\n\". Elisp
+also has a syntax for characters, that starts with a \"?\" and
+supports the same escape sequences as strings. See:
+
+ (find-elnode \"Basic Char Syntax\")
+ (find-elnode \"Character Type\")
+
+Remember - from
+
+ (find-eev-quick-intro \"2. Evaluating Lisp\" \"`M-0 M-e'\")
+
+that `M-0 M-e' and `M-0 M-E' highlight the sexp before point...
+you can use that to check the extent of a string whose
+backslashes are hard to interpret visually. For example:
+
+ \"\\
+ \\\\\\\"\\\\\\\\\"
+
+
+
+
+
+
+10. Backquote
+=============
+The backquote, \"`\", works like the quote, \"'\", but when a
+backquoted list is evaluated it is processed recursively and its
+components preceded by \",\" or \",@\" are evaluated and replaced
+by their values. The details are quite tricky - try these
+examples:
+
+ `(foo ,(+ 2 3) bar)
+ `(foo ,'(+ 2 3) bar)
+ `(foo ,(list 2 3) bar)
+ `(foo ,@(list 2 3) bar)
-;; (find-creating-links-intro)
+and see:
+
+ (find-elnode \"Backquote\")
+
+The functions in eev that use `find-elinks' typically use
+backquotes a lot. See:
+
+ (find-links-conv-intro \"3. Classification\")
+ (find-eev \"eev-elinks.el\" \"find-elinks\")
+ (find-eev \"eev-elinks.el\" \"find-efunction-links\")
+
+They are the hardest ones to read in the eev source.
