18 0launch runs a program, identified by an `INTERFACE'. If the program is not
19 already on your computer, it downloads information about which versions are
20 available, and lets you choose one to download. It will also (automatically)
21 do the same for libraries the program needs.
24 0launch will also check for updates if it has been a long time since the last
26 0launch therefore allows users to download and upgrade software without
30 An INTERFACE can be either a URL in the form `http://site/program' or
31 a local path name like `/path/to/program.xml'. For HTTP URLs, the remote
32 file is a GPG-signed XML document. Local interface files are not signed.
37 When a program is available using 0launch, it will have an associated URL. To
38 run the program, simply invoke 0launch with this as an argument:
40 .B 0launch http://rox.sourceforge.net/2005/interfaces/Edit
43 The first time you do this, details about the program are downloaded and
44 cached, and you will be prompted to confirm the versions to use. In future,
45 the program will run directly from the cache without confirmation.
48 To check for new versions:
50 .B 0launch --refresh http://rox.sourceforge.net/2005/interfaces/Edit
53 To search the list of cached URLs:
55 .B 0launch --list Edit
58 To avoid having to keep typing the full URI, use the 0alias(1) command
59 to create shortcuts to run your programs.
61 .SH COMMAND-LINE OPTIONS
64 \fB--before=VERSION\fP
65 Choosen implementation's version number must be earlier than VERSION. i.e., force
66 the use of an old version the program.
69 \fB-c\fP, \fB--console\fP
70 Never use the GUI. Normally, 0launch switches to graphical mode if it needs to
71 download anything from the network (unless DISPLAY is not set).
74 \fB-d\fP, \fB--download-only\fP
75 Download any needed files, but stop before actually running the program.
78 \fB-D\fP, \fB--dry-run\fP
79 Just print what actions would be taken.
82 \fB-f\fP, \fB--feed\fP
83 Register (or unregister) an additional source of implementations. When you get
84 a CVS version of a project, it may contain an interface XML file. To add this
85 version to the list of available versions, use --feed on this XML file. The
86 file is not copied, so you don't need to re-add the file each time it is
89 Note that if you just want to run the program, you can invoke 0launch on the
90 interface file directly (without using --feed). This will force the injector to
91 use that version, but won't affect what happens when you run it using the URI
92 as normal. Use --feed when you want to use the CVS version even when using the
93 URI, or if the program is a library (and thus referenced by URI by other
96 Note also that the stability of CVS versions may be set to 'developer', in
97 which case you must set this as the preferred stability for the interface
101 \fB-g\fP, \fB--gui\fP
102 Show the graphical policy editor. This allows you to select which version of
103 a program or library to use.
106 \fB-h\fP, \fB--help\fP
107 Show the built-in help text.
110 \fB-i\fP, \fB--import\fP
111 Import from files, not from the network. This is useful when testing an
112 interface file, to avoid uploading it to a remote server in order to download
113 it again. It might also be useful when installing from a CD or similar.
114 The file must have a trusted GPG digital signature, as when fetching from
115 the network. For unsigned interfaces, see --feed.
118 \fB-l\fP, \fB--list\fP
119 List all known interface (program) URIs. If a search term is given, only
120 URIs containing that string are shown (case insensitive).
123 \fB-m\fP, \fB--main=MAIN\fP
124 Run the specified executable instead of the default. If MAIN starts with '/'
125 then the path is relative to the implementation's top-level directory,
126 whereas otherwise it is relative to the directory containing the default
127 MAIN program. For example, if the default MAIN is \fBbin/svn\fP then
128 using \fB--main=svnadmin\fP will run \fB.../bin/svnadmin\fP instead.
131 \fB--not-before=VERSION\fP
132 Choosen implementation's version number must not be earlier than VERSION.
133 E.g., if you want to run version 2.0 or later, use \fB--not-before=2.0\fP.
136 \fB-o\fP, \fB--offline\fP
137 Run in off-line mode, overriding the default setting. In off-line mode, no
138 interfaces are refreshed even if they are out-of-date, and newer versions of
139 programs won't be downloaded even if the injector already knows about them
140 (e.g. from a previous refresh).
143 \fB-r\fP, \fB--refresh\fP
144 Fetch a fresh copy of all used interfaces. This will normally switch to GUI
145 mode, unless --console is also given. Note that using --refresh and --gui
146 together will check for updates to the GUI itself.
149 \fB-s\fP, \fB--source\fP
150 The implementation of the main (root) interface must have an architecture
151 of the form '*-src' (normally a literal "*", but could be a compatible OS).
152 Dependencies are normal implementations, not source ones.
155 \fB-v\fP, \fB--verbose\fP
156 More verbose output. Use twice for even more verbose output.
159 \fB-V\fP, \fB--version\fP
160 Display version information.
164 Configuration files (see freedesktop.org basedir spec):
166 .IP "~/.config/0install.net/injector/global"
167 Global configuration settings.
169 .IP "~/.config/0install.net/injector/trust"
170 List of trusted keys.
172 .IP "~/.config/0install.net/injector/user_overrides"
173 Per-interface settings, and extra feeds.
176 Cached data (can be re-downloaded if lost):
178 .IP "~/.cache/0install.net/interfaces"
179 Downloaded cached interface files.
181 .IP "~/.cache/0install.net/implementations"
182 Downloaded cached implementations, indexed by manifest digest.
