builtin commandline: -x for expanded tokens, supplanting -o Issue #10194 reports Cobra completions do set -l args (commandline -opc) eval $args[1] __complete $args[2..] (commandline -ct | string escape) The intent behind "eval" is to expand variables and tildes in "$args". Fair enough. Several of our own completions do the same, see the next commit. The problem with "commandline -o" + "eval" is that the former already removes quotes that are relevant for "eval". This becomes a problem if $args contains quoted () or {}, for example this command will wrongly execute a command substituion: git --work-tree='(launch-missiles)' <TAB> It is possible to escape the string the tokens before running eval, but then there will be no expansion of variables etc. The problem is that "commandline -o" only unescapes tokens so they end up in a weird state somewhere in-between what the user typed and the expanded version. Remove the need for "eval" by introducing "commandline -x" which expands things like variables and braces. This enables custom completion scripts to be aware of shell variables without eval, see the added test for completions to "make -C $var/some/dir ". This means that essentially all third party scripts should migrate from "commandline -o" to "commandline -x". For example set -l tokens if commandline -x >/dev/null 2>&1 set tokens (commandline -xpc) else set tokens (commandline -opc) end Since this is mainly used for completions, the expansion skips command substitutions. They are passed through as-is (instead of cancelling or expanding to nothing) to make custom completion scripts work reasonably well in the common case. Of course there are cases where we would want to expand command substitutions here, so I'm not sure.
