NAME 0launch — download and run programs by URL
SYNOPSIS 0launch [OPTION]... PROGRAM [ARG]...
DESCRIPTION 0launch runs the given program. PROGRAM is either a URL in the form `http://site/pro‐ gram.xml' or a local path name like `/path/to/program.xml'. If the program is not already on your computer, 0launch downloads information about which versions are available, and lets you choose one to download. It will also (automatically) do the same for any libraries the program needs. Note that much of the functionality that was originally in 0launch has now moved to 0install(1). 0launch PROGRAM ARGS is roughly equivalent to 0install run PROGRAM ARGS See the 0install(1) man-page for more information.
EXAMPLES When a program is available using 0launch, it will have an associated URL. To run the pro‐ gram, simply invoke 0launch with this as an argument: 0launch http://rox.sourceforge.net/2005/interfaces/Edit The first time you do this, details about the program are downloaded and cached, and you will be prompted to confirm the versions to use. In future, the program will run directly from the cache without confirmation. To check for new versions: 0launch --refresh http://rox.sourceforge.net/2005/interfaces/Edit To avoid having to keep typing the full URI, use the `0install add' command to create shortcuts to run your programs. COMMAND-LINE OPTIONS 0launch takes the same options as "0install run".
DEBUGGING TIPS To debug 0launch itself, use the --verbose and --console options. For example: $ 0launch -vvc http://myprog To trace or debug programs run by 0launch, use the --wrapper option. For example, to run myprog --help, displaying all calls to open(2): $ 0launch --wrapper="strace -e open" http://myprog --help If your program is interpreted (e.g. a Python program), and you wish to debug the inter‐ preter running it, you can do it like this: $ 0launch --wrapper="gdb --args python" http://myprog --help
