But if you want to contribute and send in your own question and -answers, feel free to write to us\ldots - -%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% - -\section{Presentation} - -\Question{What is {\Coq}?}\label{whatiscoq} -The {\Coq} tool is a formal proof management system: a proof done with {\Coq} is mechanically checked by the machine. -In particular, {\Coq} allows: -\begin{itemize} - \item the definition of mathematical objects and programming objects, - \item to state mathematical theorems and software specifications, - \item to interactively develop formal proofs of these theorems, - \item to check these proofs by a small certification ``kernel''. -\end{itemize} -{\Coq} is based on a logical framework called ``Calculus of Inductive -Constructions'' extended by a modular development system for theories. - -\Question{Did you really need to name it like that?} -Some French computer scientists have a tradition of naming their -software as animal species: Caml, Elan, Foc or Phox are examples -of this tacit convention. In French, ``coq'' means rooster, and it -sounds like the initials of the Calculus of Constructions CoC on which -it is based. - -\Question{Is {\Coq} a theorem prover?} - -{\Coq} comes with decision and semi-decision procedures ( -propositional calculus, Presburger's arithmetic, ring and field -simplification, resolution, ...) but the main style for proving -theorems is interactively by using LCF-style tactics. - - -\Question{What are the other theorem provers?} -Many other theorem provers are available for use nowadays. -Isabelle, HOL, HOL Light, Lego, Nuprl, PVS are examples of provers that are fairly similar -to {\Coq} by the way they interact with the user. Other relatives of -{\Coq} are ACL2, Agda/Alfa, Twelf, Kiv, Mizar, NqThm, -\begin{htmlonly}% -Omega\ldots -\end{htmlonly} -\begin{latexonly}% -{$\Omega$}mega\ldots -\end{latexonly} - -\Question{What do I have to trust when I see a proof checked by Coq?} - -You have to trust: - -\begin{description} -\item[The theory behind Coq] The theory of {\Coq} version 8.0 is -generally admitted to be consistent wrt Zermelo-Fraenkel set theory + -inaccessible cardinals. Proofs of consistency of subsystems of the -theory of Coq can be found in the literature. -\item[The Coq kernel implementation] You have to trust that the -implementation of the {\Coq} kernel mirrors the theory behind {\Coq}. The -kernel is intentionally small to limit the risk of conceptual or -accidental implementation bugs. -\item[The Objective Caml compiler] The {\Coq} kernel is written using the -Objective Caml language but it uses only the most standard features -(no object, no label ...), so that it is highly improbable that an -Objective Caml bug breaks the consistency of {\Coq} without breaking all -other kinds of features of {\Coq} or of other software compiled with -Objective Caml. -\item[Your hardware] In theory, if your hardware does not work -properly, it can accidentally be the case that False becomes -provable. But it is more likely the case that the whole {\Coq} system -will be unusable. You can check your proof using different computers -if you feel the need to. -\item[Your axioms] Your axioms must be consistent with the theory -behind {\Coq}. -\end{description} - - -\Question{Where can I find information about the theory behind {\Coq}?} -\begin{description} -\item[The Calculus of Inductive Constructions] The -\ahref{http://coq.inria.fr/doc/Reference-Manual006.html}{corresponding} -chapter and the chapter on -\ahref{http://coq.inria.fr/doc/Reference-Manual007.html}{modules} in -the {\Coq} Reference Manual. -\item[Type theory] A book~\cite{ProofsTypes} or some lecture -notes~\cite{Types:Dowek}. -\item[Inductive types] -Christine Paulin-Mohring's habilitation thesis~\cite{Pau96b}. -\item[Co-Inductive types] -Eduardo Giménez' thesis~\cite{EGThese}. -\item[Miscellaneous] A -\ahref{http://coq.inria.fr/doc/biblio.html}{bibliography} about Coq -\end{description} - - -\Question{How can I use {\Coq} to prove programs?} - -You can either extract a program from a proof by using the extraction -mechanism or use dedicated tools, such as -\ahref{http://why3.lri.fr}{\Why}, -\ahref{http://krakatoa.lri.fr}{\Krakatoa}, -\ahref{http://frama-c.com}{\Framac}, to prove -annotated programs written in other languages. - -%\Question{How many {\Coq} users are there?} -% -%An estimation is about 100 regular users. - -\Question{How old is {\Coq}?} - -The first implementation is from 1985 (it was named {\sf CoC} which is -the acronym of the name of the logic it implemented: the Calculus of -Constructions).

The -sources can be easily compiled on all platforms supporting Objective -Caml. - -%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% - -\section{The logic of {\Coq}} - -\subsection{General} - -\Question{What is the logic of \Coq?} - -{\Coq} is based on an axiom-free type theory called -the Calculus of Inductive Constructions (see Coquand \cite{CoHu86}, -Luo~\cite{Luo90} -and Coquand--Paulin-Mohring \cite{CoPa89}). It includes higher-order -functions and predicates, inductive and co-inductive datatypes and -predicates, and a stratified hierarchy of sets. - -\Question{Is \Coq's logic intuitionistic or classical?} - -{\Coq}'s logic is modular. The core logic is intuitionistic -(i.e. excluded-middle $A\vee\neg A$ is not granted by default). It can -be extended to classical logic on demand by requiring an -optional module stating $A\vee\neg A$. - -\Question{Can I define non-terminating programs in \Coq?} - -All programs in {\Coq} are terminating. Especially, loops -must come with an evidence of their termination. - -Non-terminating programs can be simulated by passing around a -bound on how long the program is allowed to run before dying. - -\Question{How is equational reasoning working in {\Coq}?} - - {\Coq} comes with an internal notion of computation called -{\em conversion} (e.g. $(x+1)+y$ is internally equivalent to -$(x+y)+1$; similarly applying argument $a$ to a function mapping $x$ -to some expression $t$ converts to the expression $t$ where $x$ is -replaced by $a$). This notion of conversion (which is decidable -because {\Coq} programs are terminating) covers a certain part of -equational reasoning but is limited to sequential evaluation of -expressions of (not necessarily closed) programs. Besides conversion, -equations have to be treated by hand or using specialised tactics. - -\subsection{Axioms} - -\Question{What axioms can be safely added to {\Coq}?} - -There are a few typical useful axioms that are independent from the -Calculus of Inductive Constructions and that are considered consistent with -the theory of {\Coq}. -Most of these axioms are stated in the directory {\tt Logic} of the -standard library of {\Coq}. The most interesting ones are - -\begin{itemize} -\item Excluded-middle: $\forall A:Prop, A \vee \neg A$ -\item Proof-irrelevance: $\forall A:Prop \forall p_1 p_2:A, p_1=p_2$ -\item Unicity of equality proofs (or equivalently Streicher's axiom $K$): -$\forall A \forall x y:A \forall p_1 p_2:x=y, p_1=p_2$ -\item Hilbert's $\epsilon$ operator: if $A \neq \emptyset$, then there is $\epsilon_P$ such that $\exists x P(x) \rightarrow P(\epsilon_P)$ -\item Church's $\iota$ operator: if $A \neq \emptyset$, then there is $\iota_P$ such that $\exists! x P(x) \rightarrow P(\iota_P)$ -\item The axiom of unique choice: $\forall x \exists! y R(x,y) \rightarrow \exists f \forall x R(x,f(x))$ -\item The functional axiom of choice: $\forall x \exists y R(x,y) \rightarrow \exists f \forall x R(x,f(x))$ -\item Extensionality of predicates: $\forall P Q:A\rightarrow Prop, (\forall x, P(x) \leftrightarrow Q(x)) \rightarrow P=Q$ -\item Extensionality of functions: $\forall f g:A\rightarrow B, (\forall x, f(x)=g(x)) \rightarrow f=g$ -\end{itemize} - -Figure~\ref{fig:axioms} is a summary of the relative strength of these -axioms, most proofs can be found in directory {\tt Logic} of the standard -library. (Statements in boldface are the most ``interesting'' ones for -Coq.) The justification of their validity relies on the interpretability -in set theory. - -\begin{figure}[htbp] -%HEVEA\imgsrc{axioms.png} -%BEGIN LATEX -\begin{center} -\ifpdf % si on est en pdflatex -\scalebox{0.65}{\input{axioms.pdf_t}} -\else -\scalebox{0.65}{\input{axioms.eps_t}} -\fi -\end{center} -%END LATEX -\caption{The dependency graph of axioms in the Calculus of Inductive Constructions} -\label{fig:axioms} -\end{figure} - -\Question{What standard axioms are inconsistent with {\Coq}?} - -The axiom of unique choice together with classical logic -(e.g. excluded-middle) are inconsistent in the variant of the Calculus -of Inductive Constructions where {\Set} is impredicative. - -As a consequence, the functional form of the axiom of choice and -excluded-middle, or any form of the axiom of choice together with -predicate extensionality are inconsistent in the {\Set}-impredicative -version of the Calculus of Inductive Constructions. - -The main purpose of the \Set-predicative restriction of the Calculus -of Inductive Constructions is precisely to accommodate these axioms -which are quite standard in mathematical usage. - -The $\Set$-predicative system is commonly considered consistent by -interpreting it in a standard set-theoretic boolean model, even with -classical logic, axiom of choice and predicate extensionality added. - -\Question{What is Streicher's axiom $K$} -\label{Streicher} - -Streicher's axiom $K$~\cite{HofStr98} is an axiom that asserts -dependent elimination of reflexive equality proofs. - -\begin{coq_example*} -Axiom Streicher_K : - forall (A:Type) (x:A) (P: x=x -> Prop), - P (eq_refl x) -> forall p: x=x, P p. -\end{coq_example*} - -In the general case, axiom $K$ is an independent statement of the -Calculus of Inductive Constructions. However, it is true on decidable -domains (see file \vfile{\LogicEqdepDec}{Eqdep\_dec}). It is also -trivially a consequence of proof-irrelevance (see -\ref{proof-irrelevance}) hence of classical logic. - -Axiom $K$ is equivalent to {\em Uniqueness of Identity Proofs} \cite{HofStr98} - -\begin{coq_example*} -Axiom UIP : forall (A:Set) (x y:A) (p1 p2: x=y), p1 = p2. -\end{coq_example*} - -Axiom $K$ is also equivalent to {\em Uniqueness of Reflexive Identity Proofs} \cite{HofStr98} - -\begin{coq_example*} -Axiom UIP_refl : forall (A:Set) (x:A) (p: x=x), p = eq_refl x. -\end{coq_example*} - -Axiom $K$ is also equivalent to - -\begin{coq_example*} -Axiom - eq_rec_eq : - forall (A:Set) (x:A) (P: A->Set) (p:P x) (h: x=x), - p = eq_rect x P p x h. -\end{coq_example*} - -It is also equivalent to the injectivity of dependent equality (dependent equality is itself equivalent to equality of dependent pairs). - -\begin{coq_example*} -Inductive eq_dep (U:Set) (P:U -> Set) (p:U) (x:P p) : -forall q:U, P q -> Prop := - eq_dep_intro : eq_dep U P p x p x. -Axiom - eq_dep_eq : - forall (U:Set) (u:U) (P:U -> Set) (p1 p2:P u), - eq_dep U P u p1 u p2 -> p1 = p2. -\end{coq_example*} - -\Question{What is proof-irrelevance} -\label{proof-irrelevance} - -A specificity of the Calculus of Inductive Constructions is to permit -statements about proofs. This leads to the question of comparing two -proofs of the same proposition. Identifying all proofs of the same -proposition is called {\em proof-irrelevance}: -$$ -\forall A:\Prop, \forall p q:A, p=q -$$ - -Proof-irrelevance (in {\Prop}) can be assumed without contradiction in -{\Coq}. It expresses that only provability matters, whatever the exact -form of the proof is. This is in harmony with the common purely -logical interpretation of {\Prop}. Contrastingly, proof-irrelevance is -inconsistent in {\Set} since there are types in {\Set}, such as the -type of booleans, that provably have at least two distinct elements. - -Proof-irrelevance (in {\Prop}) is a consequence of classical logic -(see proofs in file \vfile{\LogicClassical}{Classical} and -\vfile{\LogicBerardi}{Berardi}). Proof-irrelevance is also a -consequence of propositional extensionality (i.e. \coqtt{(A {\coqequiv} B) -{\coqimp} A=B}, see the proof in file -\vfile{\LogicClassicalFacts}{ClassicalFacts}). - -Proof-irrelevance directly implies Streicher's axiom $K$. - -\Question{What about functional extensionality?} - -Extensionality of functions is admittedly consistent with the -Set-predicative Calculus of Inductive Constructions. - -%\begin{coq_example*} -% Axiom extensionality : (A,B:Set)(f,g:(A->B))(x:A)(f x)=(g x)->f=g. -%\end{coq_example*} - -Let {\tt A}, {\tt B} be types. To deal with extensionality on -\verb=A->B= without relying on a general extensionality axiom, -a possible approach is to define one's own extensional equality on -\verb=A->B=. - -\begin{coq_eval} -Variables A B : Set. -\end{coq_eval} - -\begin{coq_example*} -Definition ext_eq (f g: A->B) := forall x:A, f x = g x. -\end{coq_example*} - -and to reason on \verb=A->B= as a setoid (see the Chapter on -Setoids in the Reference Manual). - -\Question{Is {\Prop} impredicative?} - -Yes, the sort {\Prop} of propositions is {\em -impredicative}. Otherwise said, a statement of the form $\forall -A:Prop, P(A)$ can be instantiated by itself: if $\forall A:\Prop, P(A)$ -is provable, then $P(\forall A:\Prop, P(A))$ is. - -\Question{Is {\Set} impredicative?} - -No, the sort {\Set} lying at the bottom of the hierarchy of -computational types is {\em predicative} in the basic {\Coq} system. -This means that a family of types in {\Set}, e.g. $\forall A:\Set, A -\rightarrow A$, is not a type in {\Set} and it cannot be applied on -itself. - -However, the sort {\Set} was impredicative in the original versions of -{\Coq}. For backward compatibility, or for experiments by -knowledgeable users, the logic of {\Coq} can be set impredicative for -{\Set} by calling {\Coq} with the option {\tt -impredicative-set}. - -{\Set} has been made predicative from version 8.0 of {\Coq}. The main -reason is to interact smoothly with a classical mathematical world -where both excluded-middle and the axiom of description are valid (see -file \vfile{\LogicClassicalDescription}{ClassicalDescription} for a -proof that excluded-middle and description implies the double negation -of excluded-middle in {\Set} and file {\tt Hurkens\_Set.v} from the -user contribution {\tt Paradoxes} at -\ahref{http://coq.inria.fr/contribs}{\url{http://coq.inria.fr/contribs}} -for a proof that impredicativity of {\Set} implies the simple negation -of excluded-middle in {\Set}). - -\Question{Is {\Type} impredicative?} - -No, {\Type} is stratified. This is hidden for the -user, but {\Coq} internally maintains a set of constraints ensuring -stratification. - -If {\Type} were impredicative then it would be possible to encode -Girard's systems $U-$ and $U$ in {\Coq} and it is known from Girard, -Coquand, Hurkens and Miquel that systems $U-$ and $U$ are inconsistent -[Girard 1972, Coquand 1991, Hurkens 1993, Miquel 2001]. This encoding -can be found in file {\tt Logic/Hurkens.v} of {\Coq} standard library. - -For instance, when the user see {\tt $\forall$ X:Type, X->X : Type}, each -occurrence of {\Type} is implicitly bound to a different level, say -$\alpha$ and $\beta$ and the actual statement is {\tt -forall X:Type($\alpha$), X->X : Type($\beta$)} with the constraint -$\alpha<\beta$. - -When a statement violates a constraint, the message {\tt Universe -inconsistency} appears. Example: {\tt fun (x:Type) (y:$\forall$ X:Type, X -{\coqimp} X) => y x x}. - -\Question{I have two proofs of the same proposition. Can I prove they are equal?} - -In the base {\Coq} system, the answer is generally no. However, if -classical logic is set, the answer is yes for propositions in {\Prop}. -The answer is also yes if proof irrelevance holds (see question -\ref{proof-irrelevance}). - -There are also ``simple enough'' propositions for which you can prove -the equality without requiring any extra axioms. This is typically -the case for propositions defined deterministically as a first-order -inductive predicate on decidable sets. See for instance in question -\ref{le-uniqueness} an axiom-free proof of the uniqueness of the proofs of -the proposition {\tt le m n} (less or equal on {\tt nat}). - -% It is an ongoing work of research to natively include proof -% irrelevance in {\Coq}. - -\Question{I have two proofs of an equality statement. Can I prove they are -equal?} - - Yes, if equality is decidable on the domain considered (which -is the case for {\tt nat}, {\tt bool}, etc): see {\Coq} file -\verb=Eqdep_dec.v=). No otherwise, unless -assuming Streicher's axiom $K$ (see \cite{HofStr98}) or a more general -assumption such as proof-irrelevance (see \ref{proof-irrelevance}) or -classical logic. - -All of these statements can be found in file \vfile{\LogicEqdep}{Eqdep}. - -\Question{Can I prove that the second components of equal dependent -pairs are equal?} - - The answer is the same as for proofs of equality -statements. It is provable if equality on the domain of the first -component is decidable (look at \verb=inj_right_pair= from file -\vfile{\LogicEqdepDec}{Eqdep\_dec}), but not provable in the general -case. However, it is consistent (with the Calculus of Constructions) -to assume it is true. The file \vfile{\LogicEqdep}{Eqdep} actually -provides an axiom (equivalent to Streicher's axiom $K$) which entails -the result (look at \verb=inj_pair2= in \vfile{\LogicEqdep}{Eqdep}). - -\subsection{Impredicativity} - -\Question{Why {\tt injection} does not work on impredicative {\tt Set}?} - - E.g. in this case (this occurs only in the {\tt Set}-impredicative - variant of \Coq): - -\begin{coq_example*} -Inductive I : Type := - intro : forall k:Set, k -> I. -Lemma eq_jdef : - forall x y:nat, intro _ x = intro _ y -> x = y. -Proof. - intros x y H; injection H. -\end{coq_example*} - -\begin{coq_eval} -Reset Initial. -\end{coq_eval} - - Injectivity of constructors is restricted to predicative types. If -injectivity on large inductive types were not restricted, we would be -allowed to derive an inconsistency (e.g. following the lines of -Burali-Forti paradox). The question remains open whether injectivity -is consistent on some large inductive types not expressive enough to -encode known paradoxes (such as type I above). - - -\Question{What is a ``large inductive definition''?} - -An inductive definition in {\Prop} or {\Set} is called large -if its constructors embed sets or propositions. As an example, here is -a large inductive type: - -\begin{coq_example*} -Inductive sigST (P:Set -> Set) : Type := - existST : forall X:Set, P X -> sigST P. -\end{coq_example*} - -In the {\tt Set} impredicative variant of {\Coq}, large inductive -definitions in {\tt Set} have restricted elimination schemes to -prevent inconsistencies. Especially, projecting the set or the -proposition content of a large inductive definition is forbidden. If -it were allowed, it would be possible to encode e.g. Burali-Forti -paradox \cite{Gir70,Coq85}. - - -\Question{Is Coq's logic conservative over Coquand's Calculus of -Constructions?} - -In the {\Set}-impredicative version of the Calculus of Inductive -Constructions (CIC), there are two ways to interpret the Calculus of -Constructions (CC) since the impredicative sort of CC can be -interpreted either as {\Prop} or as {\Set}. In the {\Set}-predicative -CIC, the impredicative sort of CC can only be interpreted as {\Prop}. - -If the impredicative sort of CC is interpreted as {\Set}, there is no -conservativity of CIC over CC as the discrimination of -constructors of inductive types in {\Set} transports to a -discrimination of constructors of inductive types encoded -impredicatively. Concretely, considering the impredicative encoding of -Boolean, equality and falsity, we can prove the following CC statement -DISCR in CIC which is not provable in CC, as CC has a -``term-irrelevant'' model. - -\begin{coq_example*} -Definition BOOL := forall X:Set, X -> X -> X. -Definition TRUE : BOOL := fun X x1 x2 => x1. -Definition FALSE : BOOL := fun X x1 x2 => x2. -Definition EQBOOL (x1 x2:BOOL) := forall P:BOOL->Set, P x1 -> P x2. -Definition BOT := forall X:Set, X. - -Definition BOOL2bool : BOOL -> bool := fun b => b bool true false. - -Theorem DISCR : EQBOOL TRUE FALSE -> BOT. -intro X. -assert (H : BOOL2bool TRUE = BOOL2bool FALSE). -{ apply X. trivial. } -discriminate H. -Qed. -\end{coq_example*} - -If the impredicative sort of CC is interpreted as {\Prop}, CIC is -presumably conservative over CC. The general idea is that no -proof-relevant information can flow from {\Prop} to {\Set}, even -though singleton elimination can be used. Hence types in {\Set} should -be smashable to the unit type and {\Set} and {\Type} themselves be -mapped to {\Prop}. - -%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% -\section{Talkin' with the Rooster} - - -%%%%%%% -\subsection{My goal is ..., how can I prove it?} - - -\Question{My goal is a conjunction, how can I prove it?} - -Use some theorem or assumption or use the {\split} tactic. -\begin{coq_example} -Goal forall A B:Prop, A -> B -> A/\B. -intros. -split. -assumption. -assumption. -\end{coq_example} -\begin{coq_example*} -Qed. -\end{coq_example*} - -\Question{My goal contains a conjunction as an hypothesis, how can I use it?} - -If you want to decompose a hypothesis into several hypotheses, you can -use the {\destruct} tactic: - -\begin{coq_example} -Goal forall A B:Prop, A/\B -> B. -intros. -destruct H as [H1 H2]. -assumption. -\end{coq_example} -\begin{coq_example*} -Qed. -\end{coq_example*} - -You can also perform the destruction at the time of introduction: - -\begin{coq_example} -Goal forall A B:Prop, A/\B -> B. -intros A B [H1 H2]. -assumption. -\end{coq_example} -\begin{coq_example*} -Qed. -\end{coq_example*} - -\Question{My goal is a disjunction, how can I prove it?} - -You can prove the left part or the right part of the disjunction using -{\left} or {\right} tactics.

If you compute both numbers -before comparing them, you risk to use a lot of time and space. - - -On the contrary, a function for computing the greatest of two natural numbers -is an algorithm which, called on two natural numbers -$n$ and $p$, determines whether $n\leq p$ or $p < n$. -Such a function is a \emph{decision procedure} for the inequality of - \texttt{nat}.

The decision procedure is in general -a primitive function, written in a low-level language, in the correctness -of which you have to trust. - -The standard Library of the system \emph{Coq} contains a -(constructive) proof of decidability of the order $\leq$ on -\texttt{nat} : the function \texttt{le\_lt\_dec} of -the module \texttt{Compare\_dec} of library \texttt{Arith}. - -The following code shows how to define correctly \texttt{min} and -\texttt{max}, and prove some properties of these functions. - -\begin{coq_example} -Require Import Compare_dec. - -Definition max (n p : nat) := if le_lt_dec n p then p else n. - -Definition min (n p : nat) := if le_lt_dec n p then n else p. - -Eval compute in (min 4 7). - -Theorem min_plus_max : forall n p, min n p + max n p = n + p. -Proof. - intros n p; - unfold min, max; - case (le_lt_dec n p); - simpl; auto with arith. -Qed. - -Theorem max_equiv : forall n p, max n p = p <-> n <= p. -Proof. - unfold max; intros n p; case (le_lt_dec n p);simpl; auto. - intuition auto with arith. - split. - intro e; rewrite e; auto with arith. - intro H; absurd (p < p); eauto with arith. -Qed. -\end{coq_example} - -\Question{I wrote my own decision procedure for $\leq$, which -is much faster than yours, but proving such theorems as - \texttt{max\_equiv} seems to be quite difficult} - -Your code is probably the following one: - -\begin{coq_example} -Fixpoint my_le_lt_dec (n p :nat) {struct n}: bool := - match n, p with 0, _ => true - | S n', S p' => my_le_lt_dec n' p' - | _ , _ => false - end. - -Definition my_max (n p:nat) := if my_le_lt_dec n p then p else n. - -Definition my_min (n p:nat) := if my_le_lt_dec n p then n else p. -\end{coq_example} - - -For instance, the computation of \texttt{my\_max 567 321} is almost -immediate, whereas one can't wait for the result of -\texttt{max 56 32}, using \emph{Coq's} \texttt{le\_lt\_dec}. - -This is normal. Your definition is a simple recursive function which -returns a boolean value. Coq's \texttt{le\_lt\_dec} is a \emph{certified -function}, i.e. a complex object, able not only to tell whether $n\leq p$ -or $p<n$, but also of building a complete proof of the correct inequality. -What make \texttt{le\_lt\_dec} inefficient for computing \texttt{min} -and \texttt{max} is the building of a huge proof term. - -Nevertheless, \texttt{le\_lt\_dec} is very useful. Its type -is a strong specification, using the -\texttt{sumbool} type (look at the reference manual or chapter 9 of -\cite{coqart}). Eliminations of the form -``~\texttt{case (le\_lt\_dec n p)}~'' provide proofs of -either $n \leq p$ or $p < n$, allowing easy proofs of some theorems as in -question~\ref{minmax}.

It provides the user with a -high-level ``toolbox'' for tactic creation. - -\Question{Is there any printing command in {\Ltac}?} - -You can use the {\idtac} tactic with a string argument. This string -will be printed out. The same applies to the {\fail} tactic - -\Question{What is the syntax for let in {\Ltac}?} - -If $x_i$ are identifiers and $e_i$ and $expr$ are tactic expressions, then let reads: -\begin{center} -{\tt let $x_1$:=$e_1$ with $x_2$:=$e_2$\ldots with $x_n$:=$e_n$ in -$expr$}. -\end{center} -Beware that if $expr$ is complex (i.e. features at least a sequence) parenthesis -should be added around it.

The {\tt match goal} expression matches the current -goal against a series of patterns: {$hyp_1 {\ldots} hyp_n$ \textbar- -$ccl$}. It uses a first-order unification algorithm and in case of -success, if the right-hand-side is an expression, it tries to type it -while if the right-hand-side is a tactic, it tries to apply it. If the -typing or the tactic application fails, the {\tt match goal} tries all -the possible combinations of $hyp_i$ before dropping the branch and -moving to the next one. Underscore matches all terms. - -\Question{Why can't I use a ``match goal'' returning a tactic in a non -tail-recursive position?} - -This is precisely because the semantics of {\tt match goal} is to -apply the tactic on the right as soon as a pattern unifies what is -meaningful only in tail-recursive uses. - -The semantics in non tail-recursive call could have been the one used -for terms (i.e. fail if the tactic expression is not typable, but -don't try to apply it).
