In the past, it was possible to supply a shorter `-E` flag instead of fully
|
||
|
|
specifying `--expr` every time you wished to provide an expression that would
|
||
|
|
be evaluated to produce the given command's input. This was retained for the
|
||
|
|
`--file` flag when the new CLI utilities were written with `-f`, but `-E` was
|
||
|
|
dropped.
|
||
|
|
|
||
|
|
We now restore the `-E` short form for better UX. This is most useful for
|
||
|
|
`nix eval` but most any command that takes an Installable argument should benefit
|
||
|
|
from it as well.
