doc: Add new @qcode macro for code samples which are quoted.
Macro handles options ("on") or properties ("position") more elegantly
than @code{"text"}.
* doc/interpreter/macros.texi: Add new @qcode macro.

Different actions ## are available depending on the value of @var{command}. ## ## Available commands: ## ## @table @samp ## ## @item install ## Install named packages. For example, ## ## @example ## pkg install image-1.0.0.tar.gz ## @end example ## ## @noindent ## installs the package found in the file @file{image-1.0.0.tar.gz}. ## ## The @var{option} variable can contain options that affect the manner ## in which a package is installed. These options can be one or more of ## ## @table @code ## @item -nodeps ## The package manager will disable dependency checking. With this option it ## is possible to install a package even when it depends on another package ## which is not installed on the system. @strong{Use this option with care.} ## ## @item -noauto ## The package manager will not automatically load the installed package ## when starting Octave. This overrides any setting within the package. ## ## @item -auto ## The package manager will automatically load the installed package when ## starting Octave. This overrides any setting within the package. ## ## @item -local ## A local installation (package available only to current user) is forced, ## even if the user has system privileges. ## ## @item -global ## A global installation (package available to all users) is forced, even if ## the user doesn't normally have system privileges. ## ## @item -forge ## Install a package directly from the Octave-Forge repository. This ## requires an internet connection and the cURL library. ## ## @item -verbose ## The package manager will print the output of all commands as ## they are performed. ## @end table ## ## @item update ## Check installed Octave-Forge packages against repository and update any ## outdated items. This requires an internet connection and the cURL library. ## Usage: ## ## @example ## pkg update ## @end example ## ## @item uninstall ## Uninstall named packages. For example, ## ## @example ## pkg uninstall image ## @end example ## ## @noindent ## removes the @code{image} package from the system. If another installed ## package depends on the @code{image} package an error will be issued. ## The package can be uninstalled anyway by using the @option{-nodeps} option. ## ## @item load ## Add named packages to the path. After loading a package it is ## possible to use the functions provided by the package. For example, ## ## @example ## pkg load image ## @end example ## ## @noindent ## adds the @code{image} package to the path. It is possible to load all ## installed packages at once with the keyword @samp{all}. Usage: ## ## @example ## pkg load all ## @end example ## ## @item unload ## Remove named packages from the path. After unloading a package it is ## no longer possible to use the functions provided by the package. It is ## possible to unload all installed packages at once with the keyword ## @samp{all}. Usage: ## ## @example ## pkg unload all ## @end example ## ## @item list ## Show the list of currently installed packages. For example, ## ## @example ## installed_packages = pkg ("list") ## @end example ## ## @noindent ## returns a cell array containing a structure for each installed package. ## ## If two output arguments are requested @code{pkg} splits the list of ## installed packages into those which were installed by the current user, ## and those which were installed by the system administrator. ## ## @example ## [user_packages, system_packages] = pkg ("list") ## @end example ## ## The option @qcode{"-forge"} lists packages available at the Octave-Forge ## repository. This requires an internet connection and the cURL library. ## For example: ## ## @example ## oct_forge_pkgs = pkg ("list", "-forge") ## @end example ## ## @item describe ## Show a short description of the named installed packages, with the option ## @qcode{"-verbose"} also list functions provided by the package. For example, ## ## @example ## pkg describe -verbose all ## @end example ## ## @noindent ## will describe all installed packages and the functions they provide. ## If one output is requested a cell of structure containing the ## description and list of functions of each package is returned as ## output rather than printed on screen: ## ## @example ## desc = pkg ("describe", "secs1d", "image") ## @end example ## ## @noindent ## If any of the requested packages is not installed, pkg returns an ## error, unless a second output is requested: ## ## @example ## [desc, flag] = pkg ("describe", "secs1d", "image") ## @end example ## ## @noindent ## @var{flag} will take one of the values @qcode{"Not installed"}, ## @qcode{"Loaded"}, or ## @qcode{"Not loaded"} for each of the named packages. ## ## @item prefix ## Set the installation prefix directory. For example, ## ## @example ## pkg prefix ~/my_octave_packages ## @end example ## ## @noindent ## sets the installation prefix to @file{~/my_octave_packages}. ## Packages will be installed in this directory. ## ## It is possible to get the current installation prefix by requesting an ## output argument. For example: ## ## @example ## pfx = pkg ("prefix") ## @end example ## ## The location in which to install the architecture dependent files can be ## independently specified with an addition argument. For example: ## ## @example ## pkg prefix ~/my_octave_packages ~/my_arch_dep_pkgs ## @end example ## ## @item local_list ## Set the file in which to look for information on locally ## installed packages. Locally installed packages are those that are ## available only to the current user. For example: ## ## @example ## pkg local_list ~/.octave_packages ## @end example ## ## It is possible to get the current value of local_list with the following ## ## @example ## pkg local_list ## @end example ## ## @item global_list ## Set the file in which to look for information on globally ## installed packages. Globally installed packages are those that are ## available to all users. For example: ## ## @example ## pkg global_list /usr/share/octave/octave_packages ## @end example ## ## It is possible to get the current value of global_list with the following ## ## @example ## pkg global_list ## @end example ## ## @item build ## Build a binary form of a package or packages. The binary file produced ## will itself be an Octave package that can be installed normally with ## @code{pkg}. The form of the command to build a binary package is ## ## @example ## pkg build builddir image-1.0.0.tar.gz @dots{} ## @end example ## ## @noindent ## where @code{builddir} is the name of a directory where the temporary ## installation will be produced and the binary packages will be found. ## The options @option{-verbose} and @option{-nodeps} are respected, while ## all other options are ignored. ## ## @item rebuild ## Rebuild the package database from the installed directories. This can ## be used in cases where the package database has been corrupted. ## It can also take the @option{-auto} and @option{-noauto} options to allow the ## autoloading state of a package to be changed. For example, ## ## @example ## pkg rebuild -noauto image ## @end example ## ## @noindent ## will remove the autoloading status of the image package. ## ## @end table ## @end deftypefn function [local_packages, global_packages] = pkg (varargin) ## Installation prefix (FIXME: what should these be on windows?) persistent user_prefix = false; persistent prefix = false; persistent archprefix = -1; persistent local_list = tilde_expand (fullfile ("~", ".octave_packages")); persistent global_list = fullfile (OCTAVE_HOME (), "share", "octave", "octave_packages"); confirm_recursive_rmdir (false, "local"); mlock (); ## If user is superuser set global_istall to true ## FIXME: is it OK to set this always true on windows? global_install = ((ispc () && ! isunix ()) || (geteuid () == 0)); if (isbool (prefix)) if (global_install) prefix = fullfile (OCTAVE_HOME (), "share", "octave", "packages"); archprefix = fullfile (octave_config_info ("libdir"), "octave", "packages"); else prefix = fullfile ("~", "octave"); archprefix = prefix; endif prefix = tilde_expand (prefix); archprefix = tilde_expand (archprefix); endif available_actions = {"list", "install", "uninstall", "load", ...
