27 ## @item install |
|
6070
|
28 ## Install named packages. For example, |
|
|
29 ## @example |
|
|
30 ## pkg install image-1.0.0.tar.gz |
|
|
31 ## @end example |
|
|

|
|
33 ## installs the package found in the file @code{image-1.0.0.tar.gz}. |
|
|
34 ## |

|
35 ## The @var{option} variable can contain options that affect the manner |

36 ## in which a package is installed. These options can be one or more of |
|
|
37 ## |
|
|
38 ## @table @code |
|

39 ## @item -nodeps |
|
|
40 ## The package manager will disable the dependency checking. That way it |
|
|
41 ## is possible to install a package even if it depends on another package |
|
|
42 ## that's not installed on the system. @strong{Use this option with care.} |
|

45 ## The package manager will not automatically load the installed package |

50 ## starting Octave, even if the package requests that it isn't. |
|

51 ## |
|

52 ## @item -local |

53 ## A local installation is forced, even if the user has system privileges. |

55 ## @item -global |

57 ## system privileges |
|
6614
|
58 ## |
|
6645
|
59 ## @item -verbose |

63 ## |

|
64 ## @item uninstall |
|
6070
|
65 ## Uninstall named packages. For example, |
|
|
66 ## @example |
|
|
67 ## pkg uninstall image |
|
|
68 ## @end example |
|
|
69 ## @noindent |
|
|
70 ## removes the @code{image} package from the system. If another installed |
|
|
71 ## package depends on the @code{image} package an error will be issued. |
|
|
72 ## The package can be uninstalled anyway by using the @code{-nodeps} option. |
|
6032
|
73 ## @item load |
|
6070
|
74 ## Add named packages to the path. After loading a package it is |
|
|
75 ## possible to use the functions provided by the package. For example, |
|
|
76 ## @example |
|
|
77 ## pkg load image |
|
|
78 ## @end example |
|
|
79 ## @noindent |
|
|
80 ## adds the @code{image} package to the path. It is possible to load all |
|
|
81 ## installed packages at once with the command |
|
|
82 ## @example |
|
|
83 ## pkg load all |
|
|
84 ## @end example |
|
6203
|
85 ## @item unload |
|
|
86 ## Removes named packages from the path. After unloading a package it is |
|
|
87 ## no longer possible to use the functions provided by the package. |
|
|
88 ## This command behaves like the @code{load} command. |
|
6032
|
89 ## @item list |
|
6070
|
90 ## Show a list of the currently installed packages. By requesting one or two |
|
|
91 ## output argument it is possible to get a list of the currently installed |
|
|
92 ## packages. For example, |
|
|
93 ## @example |
|
|
94 ## installed_packages = pkg list; |
|
|
95 ## @end example |
|
|
96 ## @noindent |
|
|
97 ## returns a cell array containing a structure for each installed package. |
|
|
98 ## The command |
|
|
99 ## @example |
|
|
100 ## [@var{user_packages}, @var{system_packages}] = pkg list |
|
|
101 ## @end example |
|
|
102 ## @noindent |
|
|
103 ## splits the list of installed packages into those who are installed by |
|
|
104 ## the current user, and those installed by the system administrator. |
|
6034
|
105 ## @item prefix |
|
6070
|
106 ## Set the installation prefix directory. For example, |
|
|
107 ## @example |
|
|
108 ## pkg prefix ~/my_octave_packages |
|
|
109 ## @end example |
|
|
110 ## @noindent |
|
|
111 ## sets the installation prefix to @code{~/my_octave_packages}. |
|
|
112 ## Packages will be installed in this directory. |
|
6034
|
113 ## |
|
6070
|
114 ## It is possible to get the current installation prefix by requesting an |
|
|
115 ## output argument. For example, |
|
|
116 ## @example |
|
|
117 ## p = pkg prefix |
|
|
118 ## @end example |
|
6189
|
119 ## @item local_list |
|
|
120 ## Set the file in which to look for information on the locally |
|
|
121 ## installed packages. Locally installed packages are those that are |
|
|
122 ## typically available only to the current user. For example |
|
|
123 ## @example |
|
|
124 ## pkg local_list ~/.octave_packages |
|
|
125 ## @end example |
|
|
126 ## It is possible to get the current value of local_list with the following |
|
|
127 ## @example |
|
|
128 ## pkg local_list |
|
|
129 ## @end example |
|
|
130 ## @item global_list |
|
|
131 ## Set the file in which to look for, for information on the globally |
|
|
132 ## installed packages. Globally installed packages are those that are |
|
|
133 ## typically available to all users. For example |
|
|
134 ## @example |
|
|
135 ## pkg global_list /usr/share/octave/octave_packages |
|
|
136 ## @end example |
|
|
137 ## It is possible to get the current value of global_list with the following |
|
|
138 ## @example |
|
|
139 ## pkg global_list |
|
|
140 ## @end example |
|
6645
|
141 ## @item rebuild |
|
|
142 ## Rebuilds the package database from the installed directories. This can |
|
|
143 ## be used in cases where for some reason the package database is corrupted. |
|
|
144 ## It can also take the @code{-auto} and @code{-noauto} options to allow the |
|
|
145 ## autolaoding state of a package to be changed. For example |
|
|
146 ## |
|
|
147 ## @example |
|
|
148 ## pkg rebuild -noauto image |
|
|
149 ## @end example |
|
|
150 ## |
|
|
151 ## will remove the autoloading status of the image package. |
