Instance Method Detail
Given an array of 3 words, containing
- a program name
- a partially completed word
- the last fully completed word
this method prints out, one per line, the next words which are allowed by this OptionParser.
This is a basic Bash-style command-line completion helper. See your
shell's help complete and the manual for details. It will be invoked by
bash if you set complete -C toolbelt toolbelt, for example, which says
"whenever I try to complete a word after 'toolbelt', call 'toolbelt' with
certain environment variables set". (The function uses $COMP_LINE, so
you can test your completion by invoking the program with that variable
set - see bash(1) for details.)
TODO allow flag values and arguments to be completed also.
TODO this uses an internal variable (@handlers) which seems risky. It might be better to copy the implementation and add a more stable API.
