Changelog

v0.3.0

Breaking changes

  • Renamed functions for clarity:
    • OpenJTalk.to_wav/2 → OpenJTalk.to_wav_file/2
    • OpenJTalk.to_binary/2 → OpenJTalk.to_wav_binary/2

New

  • WAV concatenation

    • OpenJTalk.Wav.concat_binaries/1
    • OpenJTalk.Wav.concat_files/1

  • Playback options

    • :playback_mode (:auto | :stdin | :file) for say/2, play_wav_binary/2, and play_wav_file/2
    • OpenJTalk.play_wav_binary/2 — play in-memory WAV bytes directly

Improvements

  • Safer, stricter option validation with OpenJTalk.validate_options!/1
  • Better error messages for invalid options and timeouts

Quick upgrade examples

{:ok, path} = OpenJTalk.to_wav_file("こんにちは", out: "/tmp/x.wav")
{:ok, wav} = OpenJTalk.to_wav_binary("こんにちは")
:ok = OpenJTalk.say("こんにちは", playback_mode: :auto)
{:ok, merged} = OpenJTalk.Wav.concat_binaries([a, b, c])

v0.2.2

Highlights

  • More robust process execution: OpenJTalk.Runner now uses MuonTrap for spawning the open_jtalk CLI. This improves timeout handling and process cleanup (useful on Nerves and in supervision trees).

Changes

  • Replace System.cmd/3 + manual Task/timeout with MuonTrap.cmd/3 in OpenJTalk.Runner.
  • Add runtime dependency: {:muontrap, "~> 1.6"}.

Notes

  • No API changes. Existing calls (OpenJTalk.to_wav/2, to_binary/2, say/2) are unaffected.
  • Builds may compile a tiny native component from MuonTrap (handled automatically).
  • Recommended for Nerves users: better handling of timeouts and zombie prevention under constrained environments.

v0.2.1

No user-visible or API changes. All updates are internal/maintenance to make builds more robust.

Build system

  • Unified script now handles vendor extraction and triplet guarding.
  • Triplet change auto-purges _build/**/obj to avoid cross-contamination.
  • Inject repo-local config.sub/config.guess into vendor trees.
  • Replace mecab/Makefile.in stub with a tiny configure patch (fixes config.status with external MeCab).
  • Streamlined installers:
    • Dictionary: extract to priv/dictionary (unwrap open_jtalk_dic_* if present).
    • Voice: stream mei_normal.htsvoice directly from the zip.
  • Centralized RPATH: $ORIGIN/../lib (Linux), @loader_path/../lib (macOS).

v0.2.0

Highlights

  • Simpler build: consolidated native build into one script; removed configure “stamp”.
  • Assets bundled by default: dictionary + Mei voice now bundled into priv/ unless opted out.
  • Wider platform support: host builds verified on Linux x86_64, Linux aarch64, and macOS 14 (arm64).
  • Cross-compile: tested MIX_TARGET=rpi4 (aarch64/Nerves).
  • Better triplet detection: inject modern config.sub/config.guess to fix errors like arm64-apple-darwin… not recognized.

Breaking / Migration

  • Env vars renamed:
    • FULL_STATIC → OPENJTALK_FULL_STATIC
    • BUNDLE_ASSETS → OPENJTALK_BUNDLE_ASSETS
  • If you previously relied on assets not being bundled, set OPENJTALK_BUNDLE_ASSETS=0.

v0.1.0
