[−][src]Module cargo_workspace2::query
Parse the query language for the CLI and other tools
The cargo-ws2
query language (ws2ql
) allows users to specify a
set of inputs, and an operation to execute on it.
Basic rules
- Inside
[]
are sets (meaning items de-dup) that don't require reparations - IF
[]
contains a/
anywhere but the beginning AND end, query becomes a path glob - IF
[]
contains/
at start and end, query becomes a regex - An operation is parsed in the order of the fields in it's struct
(so publish order is
type mod devel
, etc) - Inside
{}
you can create dependency maps with arrows. { foo < }
represents all crates that depend onfoo
{ foo < bar < }
represents all crates that depend onfoo
ANDbar
{ foo < bar |< }
represents all crates that depend onfoo
but NOT onbar
... etc.
