Atlas Dict

atlas.dict is a fast, offline terminal dictionary with a delicate design system. Part of the Atlas Suite, it ships embedded language-pair data and looks up rich entries (parts of speech, senses, examples, synonyms) in milliseconds.

✨ Features

• 📚 Offline-first: Dictionary data is embedded in the binary; no network calls.
• ⚡ Fast: O(log n) binary-search index over a packed format; per-entry zstd decoding.
• 🎨 Delicate design: Restrained lipgloss palette — airy, readable, no boxy chrome.
• 🌐 Multi-pair: Built around language pairs; new pairs add .dict files.
• 🖥️ CLI + TUI: One-shot lookups for the terminal, browse mode for exploration.

Binaries land in build/.

📚 Dictionary data

The embedded dictionary data is sourced from FreeDict — specifically the eng-tur bundle (36,589 headwords). A small set of hand-curated entries lives alongside the FreeDict data in scripts/build-dict/sources/ and takes priority on conflict. The reverse tr-en pair is auto-synthesized from the forward direction at build time.

To regenerate the embedded .dict files (e.g. after upgrading FreeDict):

gobake data           # downloads + parses + writes internal/data/*.dict
