|
|
22 ## @deftypefnx {Command} pkg @var{command} @var{option} @var{pkg_name} |
|
|
23 ## This command interacts with the package manager. Different actions will |
|
6378
|
24 ## be taken depending on the value of @var{command}. |
|
6032
|
25 ## |
|
|
26 ## @table @samp |
|
|
27 ## @item install |
|
6070
|
28 ## Install named packages. For example, |
|
|
29 ## @example |
|
|
30 ## pkg install image-1.0.0.tar.gz |
|
|
31 ## @end example |
|
|
32 ## @noindent |
|
|
33 ## installs the package found in the file @code{image-1.0.0.tar.gz}. |
|
|
34 ## |
|
|
35 ## If @var{option} is @code{-nodeps} the package manager will disable the |
|
|
36 ## dependency checking. That way it is possible to install a package even |
|
|
37 ## if it depends on another package that's not installed on the system. |
|
|
38 ## @strong{Use this option with care.} |
|
6258
|
39 ## |
|
|
40 ## If @var{option} is @code{-noauto} the package manager will not |
|
|
41 ## automatically load the installed package when starting Octave, |
|
|
42 ## even if the package requests that it is. |
|
|
43 ## |
|
|
44 ## If @var{option} is @code{-auto} the package manager will |
|
|
45 ## automatically load the installed package when starting Octave, |
|
|
46 ## even if the package requests that it isn't. |
|
6614
|
47 ## |
|
6616
|
48 ## Finally, if @var{option} is @code{-verbose} the package manager will |
|
6614
|
49 ## print the output of all of the commands that are performed |
|
6032
|
50 ## @item uninstall |
|
6070
|
51 ## Uninstall named packages. For example, |
|
|
52 ## @example |
|
|
53 ## pkg uninstall image |
|
|
54 ## @end example |
|
|
55 ## @noindent |
|
|
56 ## removes the @code{image} package from the system. If another installed |
|
|
57 ## package depends on the @code{image} package an error will be issued. |
|
|
58 ## The package can be uninstalled anyway by using the @code{-nodeps} option. |
|
6032
|
59 ## @item load |
|
6070
|
60 ## Add named packages to the path. After loading a package it is |
|
|
61 ## possible to use the functions provided by the package. For example, |
|
|
62 ## @example |
|
|
63 ## pkg load image |
|
|
64 ## @end example |
|
|
65 ## @noindent |
|
|
66 ## adds the @code{image} package to the path. It is possible to load all |
|
|
67 ## installed packages at once with the command |
|
|
68 ## @example |
|
|
69 ## pkg load all |
|
|
70 ## @end example |
|
6203
|
71 ## @item unload |
|
|
72 ## Removes named packages from the path. After unloading a package it is |
|
|
73 ## no longer possible to use the functions provided by the package. |
|
|
74 ## This command behaves like the @code{load} command. |
|
6032
|
75 ## @item list |
|
6070
|
76 ## Show a list of the currently installed packages. By requesting one or two |
|
|
77 ## output argument it is possible to get a list of the currently installed |
|
|
78 ## packages. For example, |
|
|
79 ## @example |
|
|
80 ## installed_packages = pkg list; |
|
|
81 ## @end example |
|
|
82 ## @noindent |
|
|
83 ## returns a cell array containing a structure for each installed package. |
|
|
84 ## The command |
|
|
85 ## @example |
|
|
86 ## [@var{user_packages}, @var{system_packages}] = pkg list |
|
|
87 ## @end example |
|
|
88 ## @noindent |
|
|
89 ## splits the list of installed packages into those who are installed by |
|
|
90 ## the current user, and those installed by the system administrator. |
|
6034
|
91 ## @item prefix |
|
6070
|
92 ## Set the installation prefix directory. For example, |
|
|
93 ## @example |
|
|
94 ## pkg prefix ~/my_octave_packages |
|
|
95 ## @end example |
|
|
96 ## @noindent |
|
|
97 ## sets the installation prefix to @code{~/my_octave_packages}. |
|
|
98 ## Packages will be installed in this directory. |
|
6034
|
99 ## |
|
6070
|
100 ## It is possible to get the current installation prefix by requesting an |
|
|
101 ## output argument. For example, |
|
|
102 ## @example |
|
|
103 ## p = pkg prefix |
|
|
104 ## @end example |
|
6189
|
105 ## @item local_list |
|
|
106 ## Set the file in which to look for information on the locally |
|
|
107 ## installed packages. Locally installed packages are those that are |
|
|
108 ## typically available only to the current user. For example |
|
|
109 ## @example |
|
|
110 ## pkg local_list ~/.octave_packages |
|
|
111 ## @end example |
|
|
112 ## It is possible to get the current value of local_list with the following |
|
|
113 ## @example |
|
|
114 ## pkg local_list |
|
|
115 ## @end example |
|
|
116 ## @item global_list |
|
|
117 ## Set the file in which to look for, for information on the globally |
|
|
118 ## installed packages. Globally installed packages are those that are |
|
|
119 ## typically available to all users. For example |
|
|
120 ## @example |
|
|
121 ## pkg global_list /usr/share/octave/octave_packages |
|
|
122 ## @end example |
|
|
123 ## It is possible to get the current value of global_list with the following |
|
|
124 ## @example |
|
|
125 ## pkg global_list |
