# helios-bash-completion
This program is intended to ship as `/usr/lib/helios-bash-completion` on a
Helios system. It will generate bash shell source that should be evaluated
from within `.bashrc` to enable the use of bash tab completion for some system
commands; e.g.,
```
$ /usr/lib/helios-bash-completion -g
function _helios_bash_completion {
eval $('/usr/lib/helios-bash-completion' "$COMP_CWORD" "${COMP_WORDS[@]}");
};
complete -F _helios_bash_completion 'zlogin';
complete -F _helios_bash_completion 'allocate';
complete -F _helios_bash_completion 'deallocate';
complete -F _helios_bash_completion 'ipfs';
complete -F _helios_bash_completion 'ipfstat';
complete -F _helios_bash_completion 'ipmon';
complete -F _helios_bash_completion 'ipnat';
complete -F _helios_bash_completion 'ippool';
complete -F _helios_bash_completion 'pgrep';
complete -F _helios_bash_completion 'pkill';
complete -F _helios_bash_completion 'ps';
complete -F _helios_bash_completion 'psrset';
complete -F _helios_bash_completion 'ptree';
complete -F _helios_bash_completion 'svccfg';
complete -F _helios_bash_completion 'svcadm';
complete -F _helios_bash_completion 'svcprop';
complete -F _helios_bash_completion 'svcs';
complete -F _helios_bash_completion 'zoneadm';
complete -F _helios_bash_completion 'zonecfg';
$ eval $(/usr/lib/helios-bash-completion -g)
$ complete
complete -F _helios_bash_completion deallocate
complete -F _helios_bash_completion allocate
complete -F _helios_bash_completion svcadm
complete -F _helios_bash_completion ipnat
complete -F _helios_bash_completion pgrep
complete -F _helios_bash_completion psrset
complete -F _helios_bash_completion pkill
complete -F _helios_bash_completion ippool
complete -F _helios_bash_completion zlogin
complete -F _helios_bash_completion zonecfg
complete -F _helios_bash_completion ipmon
complete -F _helios_bash_completion ipfstat
complete -F _helios_bash_completion svccfg
complete -F _helios_bash_completion svcs
complete -F _helios_bash_completion ipfs
complete -F _helios_bash_completion zoneadm
complete -F _helios_bash_completion ps
complete -F _helios_bash_completion svcprop
complete -F _helios_bash_completion ptree
```
The program attempts to be as unobtrusive as possible when it cannot guarantee
a useful match. It is also somewhat context sensitive; i.e., it ideally will
not offer completions that don't make sense at the point where the user is
requesting them with the tab key.
## Testing
A limited facility for tinkering is available. If you do not have any zones
available on your system, you can feed a set of test zone names to
the program through the environment. For example:
```
$ export COMPLETE_TEST_ZONENAMES='samuel taylor coleridge'
$ ./target/release/helios-bash-completion 2 'zonecfg' '-z' ''
COMPREPLY=(
'coleridge'
'samuel'
'taylor'
)
$ ./target/release/helios-bash-completion 1 'zlogin' ''
COMPREPLY=(
'-C'
'-E'
'-Q'
'-S'
'-d'
'-e'
'-l'
'-n'
'coleridge'
'samuel'
'taylor'
)
```
Bash appears to invoke the command for actual completion with the current
environment as well, so you can test interactively with the same overrides.
