- oak-cli: new engine.rs assembly layer maps every facade call to module Rust APIs (oaknode graph/serializer, oaktimeline commands, oakrender ticket arena, oaktask ExportTask, oakcommon config); the ffi/optional/host layers and build.rs link config are gone - oak-worker: the worker session + POSIX shm transport moved into the crate (oakrender backend + serde_json control plane); no dylib - both binaries carry zero liboakengine references (otool verified); tests green (30 cli / 41 worker)

# oak-cli (Rust)
|
|
|
|
Headless command-line consumer of the oak editor module crates — the Rust
|
|
rewrite of `cli/main.cpp` (which stays in the tree until cutover). Same
|
|
subcommands, same output format, same exit codes:
|
|
|
|
| exit | meaning |
|
|
|---|---|
|
|
| 0 | success |
|
|
| 1 | general error (bad project/media file, no sequence, I/O failure) |
|
|
| 2 | rendering unavailable or failed (e.g. no render backend) |
|
|
| 64 | usage error |
|
|
|
|
## Build and test
|
|
|
|
```sh
|
|
cargo build --release # binary: target/release/oak-cli
|
|
cargo test # unit + integration tests
|
|
```
|
|
|
|
The crate is **self-contained** (M14 R2): it links the oak* module rlibs
|
|
directly (`oaknode`, `oaktimeline`, `oakcodec`, `oakrender`, `oaktask`,
|
|
`oakcommon`) — no `liboakengine` dylib, no C ABI, no build.rs link step.
|
|
`cargo test -p oak-cli` stands alone.
|
|
|
|
## Subcommands
|
|
|
|
Every subcommand of the C++ original is implemented:
|
|
|
|
```
|
|
oak-cli info <project.ove> <start> <end> <out_dir> project name/sequences/footage
|
|
oak-cli render <project.ove> <start_seconds> <end_seconds> <out_dir>
|
|
oak-cli probe <mediafile>
|
|
oak-cli transcode <input_media> <out> [width] [--format ppm|mp4]
|
|
```
|
|
|
|
Argument validation is faithful to the C++ (`invalid start seconds`,
|
|
`invalid width`, `unknown --format` … all exit 64). The output formatters
|
|
(`src/fmt.rs`) reproduce the C++ `printf` output byte for byte and are
|
|
golden-tested against the output captured from the C++ binary on the test
|
|
fixtures (`tests/project_with_footage.ove`, `tests/demo.mp4`); the PPM and
|
|
WAV writers (`src/ppm.rs`, `src/wav.rs`) are the exact ports of the C++
|
|
`write_ppm`/`write_wav` and are unit-tested.
|
|
|
|
## Layout
|
|
|
|
```
|
|
src/
|
|
main.rs clap surface, --help/-h + unknown-command handling, dispatch
|
|
engine.rs module-native assembly layer (M14 R2): project load/create,
|
|
footage probe, sequence + clip assembly, montage resolution,
|
|
ticket rendering, synchronous export
|
|
fmt.rs golden output formatters (info/probe)
|
|
ppm.rs P6 PPM writer (f32/u8 frames)
|
|
wav.rs PCM s16 WAV writer (interleaved float samples)
|
|
cmd/ per-subcommand validation + module-crate calls
|
|
tests/cli.rs binary-level tests (exit codes, messages, usage errors)
|
|
```
