-\chapter[\Coq{} Integrated Development Environment]{\Coq{} Integrated Development Environment\label{Addoc-coqide}
-\ttindex{coqide}}
-
-The \Coq{} Integrated Development Environment is a graphical tool, to
-be used as a user-friendly replacement to \texttt{coqtop}. 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/} }.

-\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]{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 on the goal or the considered hypothesis. This is the
-``contextual menu on goals'' feature, that may be disabled in the
-preferences if undesirable.
-
-\section{Proof folding}
-
-As your script grows bigger and bigger, it might be useful to hide the proofs
-of your theorems and lemmas.
-
-This feature is toggled via the \texttt{Hide} entry of the \texttt{Navigation}
-menu. The proof shall be enclosed between \texttt{Proof.} and \texttt{Qed.},
-both with their final dots. The proof that shall be hidden or revealed is the
-first one whose beginning statement (such as \texttt{Theorem}) precedes the
-insertion cursor.
- 
-\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}
-

-\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 can be found in the subdirectory
-\verb=lib/coq/ide= of the root installation directory of \Coq{}
-(alternatively, it can be found in the subdirectory \verb=ide= of the
-source archive of \Coq{}). 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}. 
-
-This method obviously doesn't scale, that's why the preferred alternative is to
-use an Input Method Editor. On POSIX systems (Linux distros, BSD variants and
-MacOS X), you can use \texttt{uim} version 1.6 or later which provides a \LaTeX{}-style
-input method.
-
-To configure \texttt{uim}, execute \texttt{uim-pref-gtk} as your regular user.
-In the "Global Settings" group set the default Input Method to "ELatin" (don't
-forget to tick the checkbox "Specify default IM"). In the "ELatin" group set the
-layout to "TeX", and remember the content of the "[ELatin] on" field (by default
-"<Control>\"). You can now execute CoqIDE with the following commands (assuming
-you use a Bourne-style shell):
-
-\begin{verbatim}
-$ export GTK_IM_MODULE=uim
-$ coqide
-\end{verbatim}
-
-Activate the ELatin Input Method with Ctrl-\textbackslash, then type the
-sequence "\verb=\Gamma=". You will see the sequence being
-replaced by $\Gamma$ as soon as you type the second "a".
-
-\subsection[Character encoding for saved files]{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}
