0path

path manipulation for testing 0install packages

https://github.com/gfxmonk/0path 0path is a utility for making the contents of a zero install feed (including its dependencies) active in your current shell session, as if the library or application were installed globally. This should not be used as a substitute for creating a zero-install feed with your dependencies declared appropriately, but can be useful for trying out a library without going to that effort. INSTALLATION: ------------- Because 0path modifies environment variables, the suggested method of installation is to add this function to your shell's inisitalisation environment (e.g by adding to ~/.bashrc): function 0path { eval "$(0launch 'http://gfxmonk.net/dist/0install/0path.xml' "$@")"; } (for zsh users, you should remove the double quotes around "$@") USAGE: ------ Then the usage is simply e.g: 0path http://gfxmonk.net/dist/0install/mocktest.xml This will make the `mocktest` python library available to all programs run from within the current shell session. For example, you can now run a python shell and `import mocktest`. ADVANCED USAGE: --------------- If you need to add the feed's implementation to a specific environment variable (rather than one it exports): 0path http://gfxmonk.net/dist/0install/mocktest.xml PYTHONPATH This will insert mocktest's base path into your $PYTHONPATH environment variable. If providing an environment variable name, you can supply optional --insert and --mode options, which mimic the behaviour of these attributes in a zero-install <environment> binding. If you just want to run it as a once-off without installing it into your shell, you can run e.g: eval "$(0launch 'http://gfxmonk.net/dist/0install/0path.xml' <feed-uri>)"
