Its main -purpose is to allow the user to navigate forward and backward into a -\Coq{} vernacular file, executing corresponding commands or undoing -them respectively. % CREDITS ? Proof general, lablgtk, ... - -\CoqIDE{} is run by typing the command \verb|coqide| on the command -line. Without argument, the main screen is displayed with an ``unnamed -buffer'', and with a file name as argument, another buffer displaying -the contents of that file. Additionally, \verb|coqide| accepts the same -options as \verb|coqtop|, given in Chapter~\ref{Addoc-coqc}, the ones having -obviously no meaning for \CoqIDE{} being ignored. Additionally, \verb|coqide| accepts the option \verb|-enable-geoproof| to enable the support for \emph{GeoProof} \footnote{\emph{GeoProof} is dynamic geometry software which can be used in conjunction with \CoqIDE{} to interactively build a Coq statement corresponding to a geometric figure. More information about \emph{GeoProof} can be found here: \url{http://home.gna.org/geoproof/} }. - - -\begin{figure}[t] -\begin{center} -%HEVEA\imgsrc{coqide.png} -%BEGIN LATEX -\ifpdf % si on est en pdflatex -\includegraphics[width=1.0\textwidth]{coqide.png} -\else -\includegraphics[width=1.0\textwidth]{coqide.eps} -\fi -%END LATEX -\end{center} -\caption{\CoqIDE{} main screen} -\label{fig:coqide} -\end{figure} - -A sample \CoqIDE{} main screen, while navigating into a file -\verb|Fermat.v|, is shown on Figure~\ref{fig:coqide}. At -the top is a menu bar, and a tool bar below it. The large window on -the left is displaying the various \emph{script buffers}. The upper right -window is the \emph{goal window}, where goals to -prove are displayed. The lower right window is the \emph{message window}, -where various messages resulting from commands are displayed. At the -bottom is the status bar. - -\section{Managing files and buffers, basic edition} - -In the script window, you may open arbitrarily many buffers to -edit. The \emph{File} menu allows you to open files or create some, -save them, print or export them into various formats. Among all these -buffers, there is always one which is the current \emph{running - buffer}, whose name is displayed on a green background, which is the -one where Coq commands are currently executed. - -Buffers may be edited as in any text editor, and classical basic -editing commands (Copy/Paste, \ldots) are available in the \emph{Edit} -menu. \CoqIDE{} offers only basic editing commands, so if you need -more complex editing commands, you may launch your favorite text -editor on the current buffer, using the \emph{Edit/External Editor} -menu. - -\section{Interactive navigation into \Coq{} scripts} - -The running buffer is the one where navigation takes place. The -toolbar proposes five basic commands for this. The first one, -represented by a down arrow icon, is for going forward executing one -command. If that command is successful, the part of the script that -has been executed is displayed on a green background. If that command -fails, the error message is displayed in the message window, and the -location of the error is emphasized by a red underline. - -On Figure~\ref{fig:coqide}, the running buffer is \verb|Fermat.v|, all -commands until the \verb|Theorem| have been already executed, and the -user tried to go forward executing \verb|Induction n|. That command -failed because no such tactic exist (tactics are now in -lowercase\ldots), and the wrong word is underlined. - -Notice that the green part of the running buffer is not editable. If -you ever want to modify something you have to go backward using the up -arrow tool, or even better, put the cursor where you want to go back -and use the \textsf{goto} button. Unlike with \verb|coqtop|, you -should never use \verb|Undo| to go backward. - -Two additional tool buttons exist, one to go directly to the end and -one to go back to the beginning. If you try to go to the end, or in -general to run several commands using the \textsf{goto} button, the - execution will stop whenever an error is found. - -If you ever try to execute a command which happens to run during a -long time, and would like to abort it before its -termination, you may use the interrupt button (the white cross on a red circle). - -Finally, notice that these navigation buttons are also available in -the menu, where their keyboard shortcuts are given. - -\section{Try tactics automatically} -\label{sec:trytactics} - -The menu \texttt{Try Tactics} provides some features for automatically -trying to solve the current goal using simple tactics. If such a -tactic succeeds in solving the goal, then its text is automatically -inserted into the script. There is finally a combination of these -tactics, called the \emph{proof wizard} which will try each of them in -turn. This wizard is also available as a tool button (the light -bulb). The set of tactics tried by the wizard is customizable in -the preferences. - -These tactics are general ones, in particular they do not refer to -particular hypotheses. You may also try specific tactics related to -the goal or one of the hypotheses, by clicking with the right mouse -button one the goal or the considered hypothesis. This is the -``contextual menu on goals'' feature, that may be disabled in the -preferences if undesirable. - -\section{Vernacular commands, templates} - -The \texttt{Templates} menu allows to use shortcuts to insert -vernacular commands. This is a nice way to proceed if you are not sure -of the spelling of the command you want. - -Moreover, this menu offers some \emph{templates} which will automatic -insert a complex command like Fixpoint with a convenient shape for its -arguments. - -\section{Queries} - -\begin{figure}[t] -\begin{center} -%HEVEA\imgsrc{coqide-queries.png} -%BEGIN LATEX -\ifpdf % si on est en pdflatex -\includegraphics[width=1.0\textwidth]{coqide-queries.png} -\else -\includegraphics[width=1.0\textwidth]{coqide-queries.eps} -\fi -%END LATEX -\end{center} -\caption{\CoqIDE{}: the query window} -\label{fig:querywindow} -\end{figure} - - -We call \emph{query} any vernacular command that do not change the -current state, such as \verb|Check|, \verb|SearchAbout|, etc. Those -commands are of course useless during compilation of a file, hence -should not be included in scripts. To run such commands without -writing them in the script, \CoqIDE{} offers another input window -called the \emph{query window}. This window can be displayed on -demand, either by using the \texttt{Window} menu, or directly using -shortcuts given in the \texttt{Queries} menu. Indeed, with \CoqIDE{} -the simplest way to perform a \texttt{SearchAbout} on some identifier -is to select it using the mouse, and pressing \verb|F2|. This will -both make appear the query window and run the \texttt{SearchAbout} in -it, displaying the result. Shortcuts \verb|F3| and \verb|F4| are for -\verb|Check| and \verb|Print| respectively. -Figure~\ref{fig:querywindow} displays the query window after selection -of the word ``mult'' in the script windows, and pressing \verb|F4| to -print its definition. - -\section{Compilation} - -The \verb|Compile| menu offers direct commands to: -\begin{itemize} -\item compile the current buffer -\item run a compilation using \verb|make| -\item go to the last compilation error -\item create a \verb|makefile| using \verb|coq_makefile|. -\end{itemize} - -\section{Customizations} - -You may customize your environment using menu -\texttt{Edit/Preferences}. A new window will be displayed, with -several customization sections presented as a notebook. - -The first section is for selecting the text font used for scripts, goal -and message windows. - -The second section is devoted to file management: you may -configure automatic saving of files, by periodically saving the -contents into files named \verb|#f#| for each opened file -\verb|f|. You may also activate the \emph{revert} feature: in case a -opened file is modified on the disk by a third party, \CoqIDE{} may read -it again for you. Note that in the case you edited that same file, you -will be prompt to choose to either discard your changes or not. The -\texttt{File charset encoding} choice is described below in -Section~\ref{sec:coqidecharencoding} - - -The \verb|Externals| section allows to customize the external commands -for compilation, printing, web browsing. In the browser command, you -may use \verb|%s| to denote the URL to open, for example: % -\verb|mozilla -remote "OpenURL(%s)"|. - -The \verb|Tactics Wizard| section allows to defined the set of tactics -that should be tried, in sequence, to solve the current goal. - -The last section is for miscellaneous boolean settings, such as the -``contextual menu on goals'' feature presented in -Section~\ref{sec:trytactics}. - -Notice that these settings are saved in the file \verb|.coqiderc| of -your home directory. - -A gtk2 accelerator keymap is saved under the name \verb|.coqide.keys|. -This file should not be edited manually: to modify a given menu -shortcut, go to the corresponding menu item without releasing the -mouse button, press the key you want for the new shortcut, and release -the mouse button afterwards. - -For experts: it is also possible to set up a specific gtk resource -file, under the name \verb|.coqide-gtk2rc|, following the gtk2 -resources syntax -\url{http://developer.gnome.org/doc/API/2.0/gtk/gtk-Resource-Files.html}. -Such a default resource file exists in the \Coq{} library, you may -copy this file into your home directory, and edit it using any text -editor, \CoqIDE{} itself for example. - -\section{Using unicode symbols} - -\CoqIDE{} supports unicode character encoding in its text windows, -consequently a large set of symbols is available for notations. - -\subsection{Displaying unicode symbols} - -You just need to define suitable notations as described in -Chapter~\ref{Addoc-syntax}. For example, to use the mathematical symbols -$\forall$ and $\exists$, you may define -\begin{quote}\tt -Notation "$\forall$ x : t, P" := \\ -\qquad (forall x:t, P) (at level 200, x ident).\\ -Notation "$\exists$ x : t, P" := \\ -\qquad (exists x:t, P) (at level 200, x ident). -\end{quote} -There exists a small set of such notations already defined, in the -file \verb|utf8.v| of \Coq{} library, so you may enable them just by -\verb|Require utf8| inside \CoqIDE{}, or equivalently, by starting -\CoqIDE{} with \verb|coqide -l utf8|. - -However, there are some issues when using such unicode symbols: you of -course need to use a character font which supports them. In the Fonts -section of the preferences, the Preview line displays some unicode symbols, so -you could figure out if the selected font is OK. Related to this, one -thing you may need to do is choose whether Gtk should use antialiased -fonts or not, by setting the environment variable \verb|GDK_USE_XFT| -to 1 or 0 respectively. - -\subsection{Defining an input method for non ASCII symbols} - -To input an Unicode symbol, a general method is to press both the -CONTROL and the SHIFT keys, and type the hexadecimal code of the -symbol required, for example \verb|2200| for the $\forall$ symbol. -A list of symbol codes is available at \url{http://www.unicode.org}. - -Of course, this method is painful for symbols you use often. There is -always the possibility to copy-paste a symbol already typed in. -Another method is to bind some key combinations for frequently used -symbols. For example, to bind keys \verb|F11| and \verb|F12| to -$\forall$ and $\exists$ respectively, you may add -\begin{quote}\tt - bind "F11" {"insert-at-cursor" ("$\forall$")}\\ - bind "F12" {"insert-at-cursor" ("$\exists$")} -\end{quote} -to your \verb|binding "text"| section in \verb|.coqiderc-gtk2rc|. - - -% such a binding is system-dependent. We -% give here a solution for X11: -% \begin{itemize} -% \item first, using \verb|xmodmap|, bind some key combination into a -% new key name such as Fxx where xx greater that 12: for example (on a -% french keyboard) -% \begin{quote}\tt -% xmodmap -e "keycode 24 = a A F13 F13" \\ -% xmodmap -e "keycode 26 = e E F14 F14" -% \end{quote} -% will rebind "a" to F13 and "e" to F14. -% \item then add -% \begin{quote}\tt -% bind "F13" {"insert-at-cursor" ("$\forall$")}\\ -% bind "F14" {"insert-at-cursor" ("$\exists$")} -% \end{quote} -% to your \verb|binding "text"| section in \verb|.coqiderc-gtk2rc|. -% The strange \verb|∀| argument is the UTF-8 encoding for -% 0x2200, that is the symbol $\forall$. Computing UTF-8 encoding -% for a unicode can be done in various ways, including -% launching a \verb|lablgtk2| toplevel and use -%\begin{verbatim} -% Glib.Utf8.from_unichar 0x2200;; -%\end{verbatim} -%\end{itemize} - -\subsection{Character encoding for saved files} -\label{sec:coqidecharencoding} - -In the \texttt{Files} section of the preferences, the encoding option -is related to the way files are saved. - -If you have no need to exchange files with non UTF-8 aware -applications, it is better to choose the UTF-8 encoding, since it -guarantees that your files will be read again without problems. (This -is because when \CoqIDE{} reads a file, it tries to automatically -detect its character encoding.) - -If you choose something else than UTF-8, then missing characters will -be written encoded by \verb|\x{....}| or \verb|\x{........}| where -each dot is an hexadecimal digit: the number between braces is the -hexadecimal UNICODE index for the missing character. - - -\section{Building a custom \CoqIDE{} with user \textsc{ML} code} - -You can do this as described in Section~\ref{Coqmktop} for a -custom coq text toplevel, simply by adding -option \verb|-ide| to \verb|coqmktop|, that is something like -\begin{quote} -\texttt{coqmktop -ide -byte $m_1$.cmo \ldots{} $m_n$.cmo} -\end{quote} -or -\begin{quote} -\texttt{coqmktop -ide -opt $m_1$.cmx \ldots{} $m_n$.cmx} -\end{quote} - - - -% $Id: RefMan-ide.tex 8945 2006-06-10 12:04:14Z jnarboux $ - -%%% Local Variables: -%%% mode: latex -%%% TeX-master: "Reference-Manual" -%%% End: -- cgit v1.2.3
