pmacs roadmap — July 2026
Date: 2026-07-07. Produced from a five-way codebase/docs/memory sweep (core editing + persistence, LSP surface, GPU parity, extensibility + terminal, deferred-work inventory across all framing docs).
Historical planning snapshot. Several arcs below have since landed. Use
docs/agent-handoff.mdfor durable current state anddocs/active-work.mdfor open branches and recovery instructions.
Decision (2026-07-07): push Arc 1 (LSP utility surface), with Arc 2 (editing table stakes) items interleaved between sub-arcs.
State assessment (as of main @ ccb0ff6, protocol v14)
Strong. CRDT multi-frontend core; both frontends at near input/render parity (GPU exceeds TUI: minimap, wavy squiggles); LSP data layer — 13 language ids / ~8 servers, rename + cross-file definition + formatting fully working, semantic tokens + inlay hints rendering; package manager (git installs, lockfile, resolver, SHA-256 hardening); MCP client; async worker + PTY subprocess substrate; bundled line-oriented REPL package; headless GPU render CI; help system; buffer-list UI; atomic save; persisted minibuffer history.
Dark matter — built but unwired (highest leverage).
- Complete completion framework (
src/completion_framework.rs: providers for lsp/snippets/project-symbols/dabbrev; store;CompletionViewpopup insrc/completion.rs) — no keybinding, no typed-char trigger, popup never instantiated, no GPU message. HoverView(src/hover.rs),SignatureView(src/signature.rs), document-highlight store — plumbing only. Hover / signature / references / document-symbols surface as one-line modeline summaries (builtin/runtime/lsp.luamarks each "future UX work").- Code actions apply the first action blindly — no picker.
- Semantic-token pull is refresh/manual-only (no pull on attach/edit) — semantic styling can silently never appear. Arguably a bug.
- Wire-declared but unproduced protocol families:
FoldState,BlockAdornments,ResourceOffer(no fold engine / blame / diff source).
Absent. Query-replace, kill ring (single slot only), keyboard
macros, rectangles, registers, comment/uncomment, auto-indent,
snippets, auto-pairing; desktop-save/session restore, recentf,
saveplace, autosave, backups, crash recovery; theming beyond syntax
captures (all chrome hardcoded per-frontend; GPU font hardcoded);
terminal emulation (src/ansi.rs parses but discards alt-screen /
cursor addressing — no grid/scrollback); compile/grep/shell-command
modes; DAP debugging; GPU splits / multi-buffer / auto-reconnect.
Arcs, ranked by value-per-effort
Arc 1 — LSP utility surface: "light up the dark matter" — COMPLETE
The completion popup and LSP utility panels shipped across #92–#96, followed by hardening in #102, #105, and #106. Completion, hover, references, document symbols, and the supporting semantic/signature paths are now wired through both frontend contracts.
Arc 2 — Editing table stakes — COMPLETE
Query-replace (#97), the real kill ring and M-y (#103/#105/#106),
comment toggle (#107), auto-indent (#109), and auto-pairing (#110)
landed.
Arc 3 — Persistence/serialization — COMPLETE
Saveplace/recentf (#98), desktop save/restore (#99), autosave/crash-recovery (#100), and the save-clobber fix (#101) landed.
Arc 4 — Themes + extensibility surface — COMPLETE
Stages 1–3 landed as #120, #124, and #125: named ui.* faces with
daemon-resolved ThemeFacts; the live global pmacs.gpu.set_font
preference at protocol v17; and composable per-window
pmacs.statusline providers transported to semantic/GPU frontends by
protocol-v18 StatuslineSegments.
Arc 5 — Terminal, staged — COMPLETE
- Compile mode landed in #113: line-oriented PTY/ANSI output,
error-regex navigation, and
M-x compile. - Vterm Stage 1 terminal core landed in #126: compatibility parser
profiles, bounded VT screen/scrollback/reflow state, IND/NEL/RI, input
encoders, internal
TerminalManager, read-only identity buffers, process lifecycle, control-free renderer-boundary cells, and headless real-PTY acceptance. - Vterm Stage 2 TUI landed in #130: terminal-window composition, input/resize, per-context scroll/selection/copy, authenticated frontend ownership, BEL/clipboard drainage, and the strict Lua surface.
- Vterm Stage 3 protocol/GPU landed in #135: additive protocol-v19 complete frames/events, an aggregate glyph-byte bound under the unchanged transport cap, dual viewport bootstrap, authenticated semantic routing, and native fixed-cell GPU terminal rendering. The 16 MiB transport cap is preserved: the measured legal-worst frame encodes to 13,437,863 bytes under an 8 MiB aggregate glyph bound, never chunked.
Arc 6 — Folding (keystone gutter rider)
Fold engine (tree-sitter fold ranges) unblocks gutter fold markers +
the unproduced FoldState wire family + a visible feature. Git gutter
markers similarly just need a diff source.
Arc 7 — Debugging (DAP)
Greenfield but newly unblocked: gutter (breakpoint signs), process substrate (DAP = JSON-RPC over stdio, same shape as the LSP client), list-buffer panels from Arc 1b (stack/variables). Frame after Arc 1 ships — panels are reused here.
Arc 8 — GPU structural parity
Splits / multi-buffer (largest unscoped design problem), auto-reconnect after daemon restart, cursor blink, font/theme config (overlaps Arc 4).
Housekeeping (do opportunistically)
Merge PR #91 (gutter click classification + fit guard).Landed on 2026-07-07.- Machine-local handoff/experiment files are intentionally untracked; see
docs/agent-handoff.md§7. They are not repository housekeeping targets. V0.2-PREREQUISITES.mdcited twice by CHANGELOG but missing on disk — reconstruct or unlink.- README still leads with "What v0.1 ships with" — refresh.
- F-016 lua_bindings split: ~5–8 tranches left;
editor.rs(7k lines) andpmacs-gpu/main.rs(7.6k lines) splits are named follow-up arcs. - Deferred backlogs live in each framing doc's Deferred section; the consolidated sweep is reflected above.
