From c54355b0cc358c3ea0570b6c9947152bb9a50edb Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 24 Nov 2025 23:46:07 +0000 Subject: [PATCH] fix: resolve 285-character truncation in ydotool typing VoxD was truncating transcriptions at exactly 285 characters due to ydotool command-line argument length limitations. Implemented automatic text chunking for strings exceeding 250 characters. Changes: - Add intelligent text chunking for long transcriptions - Add configurable chunk size (default: 250 chars) - Add configurable inter-chunk delay (default: 50ms) - Maintain existing behavior for short text (<250 chars) - Add proper error handling and logging - Add comprehensive tests for chunking behavior - Update documentation with new typing options Tested with transcriptions up to 2000+ characters with no character loss. Short text continues to use the fast, non-chunked method automatically. Resolves truncation issue where long dictations (e.g., academic content) would cut off mid-word at 285 characters. --- README.md | 27 +++++++++ src/voxd/core/config.py | 2 + src/voxd/core/typer.py | 66 ++++++++++++++++++--- src/voxd/defaults/default_config.yaml | 2 + tests/test_core_typer.py | 82 +++++++++++++++++++++++++++ 5 files changed, 172 insertions(+), 7 deletions(-) diff --git a/README.md b/README.md index 8291ea08..7d8f4876 100644 --- a/README.md +++ b/README.md @@ -299,6 +299,10 @@ VOXD automatically discovers all `.gguf` files in the models directory on startu Edit `~/.config/voxd/config.yaml`: ```yaml +# Typing behavior (for long transcriptions) +typing_chunk_size: 250 # Characters per chunk (prevents ydotool truncation at 285 chars) +typing_inter_chunk_delay: 0.05 # Seconds between chunks (0.05 = 50ms) + # llama.cpp settings llamacpp_server_path: "llama.cpp/build/bin/llama-server" llamacpp_server_url: "http://localhost:8080" @@ -309,6 +313,29 @@ aipp_selected_models: llamacpp_server: "qwen2.5-3b-instruct-q4_k_m" ``` +#### Typing Long Text + +VOXD automatically handles long transcriptions (>285 characters) by chunking text into smaller segments.
