## Here, we specify that all subdirectories in the kernel/ and applications/ directories should be built, 
## except for those starting with a "." So, we build all kernel and application crates except hidden directories.
##
## The `members` field of this workspace is used to specify all of the crates that are built
## when the entire workspace is built, e.g., with `cargo build --workspace` or `cargo build --all`.
##
## Note that a full workspace build will *not* include crates that are explicitly excluded below.
members = [
	"theseus_features",  ## Must be included to realize global Cargo features across Theseus.
	"kernel/[!.]*/",
	"applications/[!.]*/",
]


## Default members are the crates built by default if no specific packages (crates)
## are specified when invoking `cargo build`.
## Currently, this is only relevant when overriding the Makefile's default `FEATURES`,
## which has the default value of `--workspace`, ensuring that all `members` above 
## are built even when `FEATURES` is explicitly set when invoking `make`.
##
## So far, this includes only the minimum crates required to allow Theseus to boot.

### use our own version of volatile which supports zerocopy

### use our own no_std-compatilbe getopts
getopts = { git = "https://github.com/theseus-os/getopts" }

### Patch `libc` so we can use libc-specific types when using `cfg(target_os = "theseus")`.
libc = { git = "https://github.com/theseus-os/libc", branch = "theseus" }
### Patch `core2` with newer functions from `std::io`, e.g., additional `Seek` trait functions
core2 = { path = "libs/core2" }
### Patch `bincode` because the version on crates.io doesn't handle no_std features correctly.
bincode = { git = "https://github.com/bincode-org/bincode" }

### These profiles fix the new rustc behavior of splitting one crate into many object files. 
### That messes up our module loading, which is bad!
