Environment variables

Environment variables that Drop uses are:

• DROP_HOME - if set, changes the location where Drop stores its files: configuration, environment dirs, runtime files. If not set, the XDG specification is followed.
• DROP_ENV - set by Drop and available in the sandbox, contains the id of the currently active Drop environment. Can be used to modify the shell prompt within Drop or to conditionally load some config files that should apply only in Drop or only outside of Drop.
• DROP_GVISOR_DEBUG_LOG - if set to a directory path, enables gVisor debugging and writes gVisor logs to this directory.

To change the sandboxed shell prompt on non-Debian-based systems, add the following to your shell configuration file, such as .bashrc:

if [ -n "$DROP_ENV" ]; then
    export PS1="(drop) $PS1"
fi

To configure which of your own environment variables are exposed to sandboxed programs, use the exposed_vars setting in the TOML config file.
