Prompt Concatenate Pro

Prompt Concatenate Pro

Modular prompts for ComfyUI — stack blocks, pin fields, reuse pairs, ship looks.

One node replaces the endless scroll of concatenated text widgets. Split your prompt into groups (skin, lighting, outfit, background…), toggle and reorder them, and get two clean outputs: str_pos and str_neg.

Built-in SQLite library: save layout presets (slot stacks), save prompt pairs per collection, and manage everything from a single Library manager — no more copy-paste archaeology.

Why Prompt Concatenate Pro?

| Without | With Prompt Concatenate Pro | | ---------------------------------------------- | -------------------------------------------------- | | One giant positive string | Named blocks you can enable/disable | | Re-paste the same skin/lighting every workflow | Save & load pairs from a library | | Rebuild slot lists by hand | Save & load full layout presets | | Favorites panel chaos | Pin positive/negative per group to the sidebar |

---

Features

• Group cards — title, positive, negative, drag reorder, priority, collapse, duplicate, per-group enable toggle
• Join engine — merges enabled groups with , , skips empty, normalizes commas and spacing
• Pin to sidebar — each group's pos/neg appears in ComfyUI Inputs / Favorites (Group | positive, Group | negative)
• Duplicate pairs — copy a group as Title (2) while Save/Load still use the base shelf (Pose)
• Layout presets (Stacks) — save the current slot list + order; optional folder (category)
• Prompt pairs — save/load pos+neg per collection (e.g. shelf named after the slot)
• Library manager — rename, move, delete stacks & prompts; edit full prompt text in a centered editor
• Local SQLite — db/presets.sqlite, auto-created on first use

---

Install

1. Clone into ComfyUI/custom_nodes/:

   git clone https://github.com/StoneZol/prompt-concatenate-pro.git
   

2. Restart ComfyUI (or refresh the browser after a hot reload).

3. Add node: Prompt Concatenate Pro (same folder name in the node picker).

No pip dependencies — Python 3.8+ stdlib + SQLite only.

---

Quick start

1. Add Prompt Concatenate Pro to your graph.
2. Add group — name it (skin, lighting, …), fill positive / negative.
3. Connect str_pos → CLIP Text Encode (positive), str_neg as needed.
4. Save preset — snapshot your current slot layout (names + order).
5. On a group card: Save pair / Load pair — store or recall that block's prompts in a collection.
6. Manage library — edit, move, or delete saved stacks and prompts.

Save a layout preset

Snapshot the current slots (Skin · Bg · Light) into a named stack, optionally in a folder.

Save a prompt pair

From a group card, store that block's positive / negative under a collection (defaults to the group title).

Load a layout

Search stacks by folder and apply the slot list back onto the node.

Load a pair

Browse the current collection (or other collections). Click the document icon to preview the full positive / negative before loading.

Concepts

Groups (on the node)

Live editing surface. Each group has title, positive, negative, order, and enabled.
Sidebar labels (Skin | positive) are stamped when the group is created. Renaming the group on the node is local — it does not rewrite those labels and does not rename library collections.

Stacks (layout presets)

Saved from Save preset in the node header.
Stores slot names + order only (empty pairs). Optional folder; default bucket is Uncategorised.

Prompt pairs

Saved from Save pair on a group card.
Stored in a collection (defaults to the group's title). Includes title, description, positive, negative.

Collections vs folders

| Term | Used for | Table | | -------------- | ----------------------- | ---------------- | | Folder | Layout presets (stacks) | layout_folders | | Collection | Prompt pairs | categories |

Collections are created when you Save pair, not when you save a layout preset.

---

Pinning to the sidebar

Each group exposes two hidden STRING widgets for ComfyUI's native pin UI:

• Skin | positive
• Skin | negative

Pin them from the node Inputs panel or Favorites. Edits sync both ways with the group card.

---

Library manager

Manage library (full-width button under Save / Load preset):

• Stacks — layout presets by folder; rename folder, move stack to Uncategorised, delete
• Prompts — pairs by collection; full editor for metadata + prompt text
• Show empty — reveal empty folders / collections
• Search on both tabs

Edit a prompt in a centered dialog: name, collection, description stay fixed; positive / negative scroll independently.

---

Join preview (debug)

Optional console logging while tuning join behavior.

In js/pc/config.json:

"debug_join": true

Or in the browser console:

localStorage.setItem("pc-debug-join", "1"); // on
localStorage.setItem("pc-debug-join", "0"); // off

Python also logs joined strings when the node executes ([PromptConcatenatePro] str_pos … in the terminal).

Set "debug_join": false before release if you don't need it.

Known issues

• Vue Nodes 2.0 — toggling Vue mode can briefly leave duplicate layout glitches on the canvas; refresh the page to heal. Layout data in the widget is unaffected.
• Two installs — ComfyUI loads every folder in custom_nodes. If Prompt Concatenate Pro is there twice (for example a git clone and a Manager/registry install), you get two nodes, two presets.sqlite files, and HTTP routes registered from whichever copy loaded first. Keep a single folder.
