Built a quick, sub-15ms Rust CLI/TUI to pack repos into prompts without burning 40k tokens on lockfiles and junk

Whenever I feed codebases into local models (Qwen, DeepSeek R1) or API models, the biggest annoyance is prompt pollution: - Lockfiles (Cargo.lock, package-lock.json) burning 30,000+ tokens for zero reason. - SVGs, binary files, or build artifacts slipping into the context. - Existing packers taking 3-4 seconds just to generate the prompt. I built a small tool called repOx to fix this for my own workflow. GitHub: https://github.com/WVDYC/repOx Features: Speed: Written in Rust, takes ~14ms to dump a 3k-file repo. Lazygit-style TUI (repox -i): Opens a fast terminal UI where you can uncheck folders with Space, preview files, search with /, and watch a live token gauge before copying. Clean output: Strips lockfiles and binaries by default using Git NUL-byte heuristics. Dumps straight to clipboard (repox -c). Offline Tokenizer: Supports token budgets for Claude, GPT, Gemini, DeepSeek, and Llama contexts so you know beforehand if you're exceeding your window. One-line install (macOS / Linux): curl -fsSL https://raw.githubusercontent.com/WVDYC/repOx/main/install.sh | sh Code is open source (MIT / Apache). Curious what you all currently use for feeding code into LLMs and if there are specific prompt templates you'd like added. submitted by /u/Wvdy_CC [link] [comments]
