## Summary
- add `ReducerContext::database_identity()` in Rust bindings
- deprecate `ReducerContext::identity()` and keep it as a compatibility
alias
- update reducer docs example to use `ctx.database_identity()`
- add C# reducer-context equivalent: `DatabaseIdentity` and obsolete
`Identity` alias
- update Rust/C# module test callsites to the new API name
- update C# codegen snapshots for generated `ReducerContext` API output
## Why
Issue #3201 reports user confusion between reducer `ctx.identity()`
(database/module identity) and `ctx.sender`. This change clarifies
naming while preserving compatibility.
## Validation
- `cargo check -p spacetimedb -p module-test` (Passed)
- `dotnet test crates/bindings-csharp/Codegen.Tests/Codegen.Tests.csproj
--nologo` (Passed)
- `dotnet test crates/bindings-csharp/Runtime.Tests/Runtime.Tests.csproj
--nologo` (Failed) pre-existing unrelated failure:
- `Runtime.Tests/JwtClaimsTest.cs(10,23): CS1729: 'JwtClaims' does not
contain a constructor that takes 2 arguments`
## Compatibility
- Rust: `identity()` still works but is deprecated in favor of
`database_identity()`.
- C#: `Identity` still works but is marked `[Obsolete]` in favor of
`DatabaseIdentity`.
Closes#3201
# Description of Changes
This PR implements support for the `spacetime.json` configuration file
that can be used to set up common `generate` and `publish` targets. An
example of `spacetime.json` could look like this:
```
{
"dev_run": "pnpm dev",
"generate": [
{ "out-dir": "./foobar", "module-path": "region-module", "language": "c-sharp" },
{ "out-dir": "./global", "module-path": "global-module", "language": "c-sharp" },
],
"publish": {
"database": "bitcraft",
"module-path": "spacetimedb",
"server": "local",
"children": [
{ "database": "region-1", "module-path": "region-module", server: "local" },
{ "database": "region-2", "module-path": "region-module", server: "local" }
]
}
}
```
With this config, running `spacetime generate` without any arguments
would generate bindings for two targets: `region-module` and
`global-module`. `spacetime publish` without any arguments would publish
three modules, starting from the parent: `bitcraft`, `region-1`, and
`region-2`. On top of that, the command `pnpm dev` would be executed
when using `spacetime dev`.
It is also possible to pass additional command line arguments when
calling the `publish` and `generate` commands, but there are certain
limitations. There is a special case when passing either a module path
to generate or a module name to publish. Doing that will filter out
entries in the config file that do not match. For example, running:
```
spacetime generate --project-path global-module
```
would only generate bindings for the second entry in the `generate`
list.
In a similar fashion, running:
```
spacetime publish region-1
```
would only publish the child database with the name `region-1`
Passing other existing arguments is also possible, but not all of the
arguments are available for multiple configs. For example, when running
`spacetime publish --server maincloud`, the publish command would be
applied to all of the modules listed in the config file, but the
`server` value from the command line arguments would take precedence.
Running with arguments like `--bin-path` would, however, would throw an
error as `--bin-path` makes sense only in a context of a specific
module, thus this wouldn't work: `spacetime publish --bin-path
spacetimedb/target/debug/bitcraft.wasm`. I will throw an error unless
there is only one entry to process, thus `spacetime publish --bin-path
spacetimedb/target/debug/bitcraft.wasm bitcraft` would work, as it
filters the publish targets to one entry.

The config file in itself is not overly complex, but when coupled with
the CLI it is somewhat tricky to get right. There are also some changes
that I had to make to how clap arguments are validated - because the
values can now come from both the config file and the clap config, we
can't use some of the built-in validations like `required`, or at least
I haven't found a clean way to do so.
# Testing
I've added some automated tests, but more tests and manual testing is
coming.

# Description of Changes
Modules are like programs, databases are like processes. Your client
connects to a remote database, not a remote module.
<!-- Please describe your change, mention any related tickets, and so on
here. -->
# API and ABI breaking changes
Yep!
# Expected complexity level and risk
2? I made this change with find + replace, and it's possible that I
borked the edit, or missed some reference somehow. It seems unlikely,
however, that this change will have deeper implications we haven't
considered.

N/a
# Description of Changes
This adds C++ server bindings (/crate/bindings-cpp) to allow writing C++
20 modules.
- Emscripten WASM build system integration with CMake
- Macro-based code generation (SPACETIMEDB_TABLE, SPACETIMEDB_REDUCER,
etc)
- All SpacetimeDB types supported (primitives, Timestamp, Identity,
Uuid, etc)
- Product types via SPACETIMEDB_STRUCT
- Sum types via SPACETIMEDB_ENUM
- Constraints marked with FIELD* macros
# API and ABI breaking changes
None
# Expected complexity level and risk
2 - Doesn't heavily impact any other areas but is complex macro C++
structure to support a similar developer experience, did have a small
impact on init command
# Testing
- [x] modules/module-test-cpp - heavily tested every reducer
- [x] modules/benchmarks-cpp - tested through the standalone (~6x faster
than C#, ~6x slower than Rust)
- [x] modules/sdk-test-cpp
- [x] modules/sdk-test-procedure-cpp
- [x] modules/sdk-test-view-cpp
- [x] Wrote several test modules myself
- [x] Quickstart smoketest [Currently in progress]
- [ ] Write Blackholio C++ server module
