-# Dynamic Shell Autocompletion for Artists/Albums/Tracks
-
-## Problem
-
-`rsp play <query>` and `rsp queue <query>` accept freeform strings. No tab-completion for artists, albums, or tracks from the SQLite library DB. User must type full path or query blindly.
-
-## Approach: Direct DB read (no daemon dependency)
-
-Hidden CLI subcommand `rsp complete <entity> [prefix]` that:
-1. Opens DB directly (same as `rsp scan` at cli.rs:204-205)
-2. Queries with prefix match
-3. Prints newline-separated results to stdout
-4. Returns empty on error (never crash completion)
-
-Works with or without daemon running. SQLite prefix query is ~1ms.
-
-## Steps
-
-### 1. Add completion query methods to `Database` (`src/database.rs`)
-
-```
-pub fn complete_artists(&self, prefix: &str) -> SqlResult<Vec<String>>
-pub fn complete_albums(&self, prefix: &str) -> SqlResult<Vec<String>>
-pub fn complete_tracks(&self, prefix: &str) -> SqlResult<Vec<String>>
-```
-
-SQL:
-- artists: `SELECT name FROM artists WHERE name LIKE ? ORDER BY name`
-- albums: `SELECT title FROM albums WHERE title LIKE ? ORDER BY title`
-- tracks: `SELECT title FROM tracks WHERE title LIKE ? ORDER BY title`
-
-Prefix `"a"` → `LIKE 'a%'`. Limit results (e.g. 25).
-
-### 2. Add hidden `DbComplete` subcommand (`src/cli.rs`)
-
-```
-#[clap(hide = true)]
-DbComplete {
-    entity: String,  // "artists", "albums", "tracks"
-    prefix: Option<String>,
-}
-```
-
-Dispatch in `Cli::run()`:
-```
-Commands::DbComplete { entity, prefix } => {
-    let config = Config::load()?;
-    let db = Database::open(&config)?;
-    let results = match entity.as_str() { ... };
-    for r in results { println!("{r}"); }
-}
-```
-
-Errors → silent empty (stderr) so completion never breaks.
-
-### 3. Filter `DbComplete` out of generated completions (like `Completions`)
-
-In `Completions` generation (cli.rs:238-253): filter `s.get_name() != "db-complete"`.
-
-### 4. Dynamic zsh completion function
-
-Replace `/usr/share/zsh/site-functions/_rsp` with a wrapper that:
-
-```zsh
-#compdef rsp
-# Static part (generated by clap)
-_rsp_command() { ... }  # clap-generated
-
-# Dynamic overrides
-_rsp() {
-  case $line[1] in
-    play|queue)
-      if compset -P 1; then
-        # Subcommand → complete tracks/artists/albums
-        local -a suggestions
-        suggestions=(${(f)"$(rsp complete tracks "$words[CURRENT]")"})
-        suggestions+=(${(f)"$(rsp complete artists "$words[CURRENT]")"})
-        suggestions+=(${(f)"$(rsp complete albums "$words[CURRENT]")"})
-        compadd -a suggestions
-      else
-        _rsp_command
-      fi
-      ;;
-    *)
-      _rsp_command
-      ;;
-  esac
-}
-```
-
-For `play <query>`, complete artists + albums + tracks.
-Where artists have the biggest priority, then comes albums and at the end tracks.
-Additionally, when we have autocompleted an artist, put a '/' after the name. Next autocompletions will autocomplete albums/tracks, do the same for albums.
-
-### 5. Update `Completions` generation to produce the wrapper
-
-In `cli.rs`, after `generate()` for zsh, append the dynamic wrapper code. The generated file becomes: `clap-generated-code` + `_rsp() { ... dynamic ... }`.
-
-Or simpler: write the wrapper as `completions/_rsp.dynamic` and concatenate in install.sh.
-
-### 6. Update `install.sh`
-
-Replace `rsp completions zsh | sudo tee ...` with:
-```bash
-(rsp completions zsh; echo; cat completions/_rsp) | sudo tee "$dest"
-```
-
-### 7. Update `TODO.md`
-
-Mark "[x] Dynamic autocompletion of artists, albums and tracks"
-
-### 8. Tests
-
-Add tests in `tests/database.rs`:
-- `test_complete_artists_prefix`
-- `test_complete_albums_prefix`
-- `test_complete_tracks_prefix`
-- `test_complete_empty_db`
-- `test_complete_no_match`
-
-Need a test helper that creates a temp DB with known data, runs queries, checks results.
-
-## Files changed
-
-| File | Change |
-|------|--------|
-| `src/database.rs` | +3 pub methods (complete_artists/albums/tracks) |
-| `src/cli.rs` | +DbComplete variant, +dispatch, +filter in Completions |
-| `completions/_rsp.dynamic` (new) | zsh dynamic completion wrapper |
-| `install.sh` | concatenate static + dynamic |
-| `tests/database.rs` | +completion query tests |
-
-## Future: fish/bash
-
-Same pattern. Fish uses `complete -c rsp -n '__fish_seen_subcommand_from play' -a '(rsp complete tracks (commandline -ct))'`. Bash uses `COMPREPLY=($(compgen -W "$(rsp complete tracks "$cur")" -- "$cur"))`. Start with zsh only (user's shell).
