Release v0.1.0

Initial public release of ane — a chord-based terminal code editor built for humans and agents.

Features

• Chord engine: A 4-part chord system (action, positional, scope, component) for composable, expressive edits. Short form (cifc) and long form (ChangeInsideFunctionContents) are both accepted. The engine runs in three stages: parse, resolve (LSP lookup if needed), patch.

  • Actions: change, delete, replace, yank, append, prepend, insert, jump
  • Positionals: inside, entire, after, before, until, to, outside, next, previous
  • Scopes: line, buffer, function, variable, struct, member, delimiter
  • Components: beginning, contents, end, value, parameters, arguments, name, self

• LSP engine: Centralized language server lifecycle manager. Detects the project language, installs the server if missing, starts it in the background, and gates LSP-dependent chords until the server is ready. The TUI status bar reflects the current LSP state at all times. Rust (rust-analyzer) supported at launch; Go, TypeScript/JavaScript, and Python added via WI-0008.

• Exec mode (ane exec): One-shot headless CLI edits for code agents and scripts. Accepts a chord and a file path, writes the file, and outputs a unified diff to stdout. Yank chords output the selected text instead. Supports stdin piping for values (value:-). No LSP startup delay for line/buffer/delimiter chords.

• TUI: Interactive terminal editor with two modes — Chord mode (default) and Edit mode (Ctrl-E). File tree pane (Ctrl-T), chord history recall (Ctrl-R), save (Ctrl-S), and exit confirmation modal (Ctrl-C). Short-form chords auto-execute when the cursor sits inside a recognized construct.

• Jump action and delimiter scope: j (jump) moves the cursor to named code constructs without modifying the buffer. The to positional and delimiter scope (d) for bracket/quote/tag targeting are also included.

• Tree-sitter syntax highlighting: Universal baseline highlighting computed synchronously on file open (<2ms). LSP semantic tokens overlay once the server is ready, adding type-aware colors. Language support: Rust, Go, TypeScript/JavaScript, Python (tree-sitter + LSP), Markdown (tree-sitter only).

• Application-managed mouse selection: Mouse selection in the TUI excludes line-number gutters from the clipboard. Selection is tracked in logical buffer coordinates and copied via OSC 52. Hold Shift during click-drag to fall back to native terminal selection.

• Code agent integration:

  • ane init <agent> installs an embedded skill file into the agent's skill directory, teaching it the chord system and exec mode. Supported agents: claude, codex, gemini, opencode, cline, maki, charm.
  • ane::core public crate API exposes ChordEngine, LspEngine, Buffer, all chord types, and tool_definition() (a ready-to-serialize LLM tool definition). The frontends feature flag (on by default) gates CLI/TUI dependencies; library consumers use default-features = false.

• Multi-language LSP support: Go (gopls), TypeScript/JavaScript (vtsls), and Python (basedpyright) added alongside Rust (rust-analyzer). Each language has a capability matrix entry declaring tree-sitter and LSP support independently.
