We could use aliases in the meantime:
alias compsave='local _oprefix$_level _oiprefix$_level _oargv$_level _ocurrent$_level; \
eval "_oprefix${_level}=\"\$PREFIX\"; \
_oiprefix${_level}=\"\$IPREFIX\"; \
_oargv${_level}=( \"\$@\" ); \
_ocurrent${_level}=\"\$CURRENT\""'
alias compreset='eval "PREFIX=\"\$_oprefix${_level}\"; \
IPREFIX=\"\$_oiprefix${_level}\"; \
argv=( \"\$_oargv${_level}[@]\" ); \
CURRENT=\"\$_ocur${_level}\""'
alias __if='(( $+_level )) || local _level=0; (( _level++ )); compsave; if'
alias __elif='compreset; elif'
alias __else='compreset; else'
alias __fi='compreset; fi; unset _oprefix$_level _oiprefix$_level _oargv$_level _ocurrent$_level; (( _level-- ))'
With this one can use `__if ... __elif ... __else ... __fi' for tests
in completion functions (even nested) without having to worry about
calling comp{save,reset}.
But of course that's quite expensive...
Bye
Sven
