Project State

Project Reference

See: .planning/PROJECT.md (updated 2026-02-28)

Core value: Users can connect via SSH and seamlessly browse a vault of linked markdown documents with retro BBS aesthetics Current focus: PROJECT COMPLETE — All 4 phases and 10 plans executed

Current Position

Phase: 4 of 4 (BBS Polish and Live Content) — COMPLETE Plan: 3 of 3 in current phase (04-01, 04-02, 04-03 all done) Status: PROJECT COMPLETE — live reload with 300ms debounce, scroll preservation, and non-fatal watcher failure handling Last activity: 2026-03-01 - Completed quick task 1: Arrow key navigation and directory description column

Progress: [██████████] 100%

Accumulated Context

Decisions

Decisions are logged in PROJECT.md Key Decisions table. Recent decisions affecting current work:

Pre-Phase 1: Verify edition = "2024" compiles before changing to 2021 — leave it if cargo build succeeds
Pre-Phase 1: Use pulldown-cmark event-based approach for markdown parsing (not comrak)
Pre-Phase 1: No tokio/async runtime — synchronous event loop only
Pre-Phase 2: Choose wiki-link parsing strategy before implementation (regex pre-pass vs post-parse interception)
01-01: Resolve relative vault_path against config file parent dir (not cwd) — bbs.toml lives next to binary
01-01: detect_login_shell() called before parse_cli() — both read argv[0], parse_cli strips the dash
01-02: Use ratatui::crossterm re-export path — crossterm is transitive dep, not direct dep in Cargo.toml
01-02: SIGINT not registered via signal-hook — crossterm key events handle double-press Ctrl+C in Plan 03
01-02: restore_terminal() skips ratatui::restore() — that would call LeaveAlternateScreen (never entered)
01-03: show_goodbye() called after restore_terminal() — terminal must be in cooked mode before println! is safe
01-03: app_config stored in App struct for Phase 2 access — vault_path accessible inside event loop
01-03: Quit prompt cleared on any non-Ctrl+C key — pressing any key dismisses double-press window
02-01: LinesWithNewlines iterator added to preserve trailing \n for syntect grammar correctness
02-01: mod declarations added to main.rs during Plan 02 (not Plan 03) — compiler needs them to check renderer.rs
02-01: syntect default-fancy feature uses pure-Rust fancy-regex (avoids Oniguruma C lib)
02-02: Full emit_code_block and emit_table written in Task 1 (not stubs) — avoids throwaway code
02-02: Box width for code blocks capped at terminal width — prevents border overflow on long lines
02-02: Table n_cols derived from max(alignments.len(), max row length) — handles malformed GFM tables
[Phase 02-03]: raw_content stored in App for resize re-render — avoids disk re-read on window resize
[Phase 02-03]: draw_error_screen() unified for Missing and Error via Option<&str> reason parameter
[Phase 02-03]: Scroll keys placed before _ catch-all — j/k during quit prompt does not dismiss it
[Phase 03-navigation-and-links]: vault_path added to render_markdown for render-time broken wiki-link detection
[Phase 03-navigation-and-links]: Broken wiki-links checked at render time; standard links deferred to navigation time
[Phase 03-navigation-and-links]: link_span_start_count field tracks span array position at Tag::Link Start for span_len computation
[Phase 03-02]: navigate_to does NOT push to history on Missing/ReadError — user stays on current page conceptually
[Phase 03-02]: navigate_back/forward re-loads from disk (no render cache) per research recommendation
[Phase 03-02]: Draw-time REVERSED uses lines.clone() per frame — stored lines unchanged for resize re-render
[Phase 03-02]: Span overlap detection extended beyond plan spec — catches spans starting before col_offset that extend into link range
[Phase 04]: resolve_wiki_link() Directory sentinel placed before rfind('/') split — prevents 'directory' being misinterpreted as a subpath prefix
[Phase 04]: navigate_back/forward use if/else-if branch for directory not load_document — avoids spurious Missing document state for virtual page
[Phase 04]: handle_resize() returns early for directory — raw_content is None for virtual pages, prevents stale-content confusion
[Phase 04-03]: Watch parent directory (not the file itself) — survives atomic saves where editors rename temp file over target
[Phase 04-03]: try_recv drain loop per poll iteration — drains all queued events, debounce collapses burst into single reload
[Phase 04-03]: FileWatcher initialized in main.rs before App::new() — avoids self-referential ownership, keeps constructor pure
[Phase 04-03]: Non-fatal watcher failure — warning printed, None passed to App, app runs without live reload
[quick-1]: Bare Left/Right match arms placed after Alt+Left/Alt+Right guards — match order ensures Alt combos consumed first
[quick-1]: BufReader + take(20) for frontmatter parsing — avoids loading entire large files
[quick-1]: span_len covers only [name] bracket not description — keeps Tab-cycling highlight correct

Pending Todos

None. Project complete. Quick task 1 executed.

Blockers/Concerns

All blockers resolved:

REND blocker resolved: renderer.rs uses no Widget trait at all
NAV path traversal resolved: is_within_vault() with canonicalize + starts_with guards all link resolution in vault.rs
LIVE resolved: notify 6.1 API verified; parent-directory watch pattern avoids inotify exhaustion and survives atomic saves
