The shell function
__python_argcomplete_scan_head
in the completion setting (argcomplete/bash_completion.d/_python-argcomplete
) uses theread
builtin without specifying variable names. This stores theread
result in the shell variableREPLY
. Then,__python_argcomplete_scan_head
checks the value ofREPLY
. A problem is that this will clobber the users' values of the global shell variableREPLY
on an attempt of completion. We should declare theREPLY
as a local variable in the shell function__python_argcomplete_scan_head
.
