[workspace]
resolver = "2"
## 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.
default-members = [
"theseus_features", ## Must be included to realize global Cargo features across Theseus.
"kernel/nano_core",
]
exclude = [
## Exclude the build directories
"build",
"target",
## Exclude the `aarch64` directory, which is a WIP port that currently must be built separately.

## Exclude configuration, tools, scripts, etc
"cfg",
"compiler_plugins",
"scripts",
"tools",
## Exclude old components
"old_crates",

## Exclude third-party libs and ports for now.
## This allows Theseus crates that *are* included in a build to pull these
## third-party crates in only when needed to fulfill their dependencies.

## Below, we exclude things that should NEVER be considered part of Theseus's workspace.
########################################################################################
##
## Note that if you simply need to exclude something from a custom build of Theseus,
## it's best to add that crate as an optional dependency and then create a feature
## to enable it in a non-workspace build (i.e., when not calling `cargo build --all`).
## Exclude kernel crates that exist purely for testing or benchmarking purposes.
"kernel/libtest",
"kernel/test_thread_local",

## Exclude benchmark-related crates in all builds; they must be explicitly included via features.

[patch.crates-io]
### use our own version of volatile which supports zerocopy
volatile = { git = "https://github.com/theseus-os/volatile" }
### use our own no_std-compatilbe getopts
getopts = { git = "https://github.com/theseus-os/getopts" }
### use the latest version of smoltcp from github; the one on crates.io is out of date
smoltcp = { git = "https://github.com/m-labs/smoltcp" }
### 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!
