# ComfyUI-Nikosis-Nodes
A collection of custom nodes for [ComfyUI](https://github.com/comfyanonymous/ComfyUI) designed to enhance your workflow with utilities for aspect ratio generation,
multi-style prompt selection, and text concatenation.
## Installation
### **Recommended**
* Install via [ComfyUI-Manager](https://github.com/ltdrdata/ComfyUI-Manager).
### **Manual**
* Navigate to `ComfyUI/custom_nodes` in your terminal (cmd).
* Clone the repository under the `custom_nodes` directory using the following command:
```
git clone https://github.com/Nikosis/ComfyUI-Nikosis-Nodes comfyui-nikosis-nodes
cd comfyui-nikosis-nodes
```
* Install dependencies in your Python environment.
* For Windows Portable, run the following command inside `ComfyUI\custom_nodes\comfyui-nikosis-nodes`:
```
..\..\..\python_embeded\python.exe -m pip install -r requirements.txt

pip install -r requirements.txt
* Restart ComfyUI
# Nodes Overview
## 🖌️ Aspect Ratio (nikosis)
**File:** `nodes/aspect_ratio_nikosis.py`
**Category:** Nikosis/Utilities
### Description
Generates an empty latent tensor for SDXL (4 channels) or SD3/Flux (16 channels) with customizable aspect ratios and dimensions.
### Inputs
- **model_type**: Choose between SDXL (4 channels) or SD3/Flux (16 channels).
- **aspect_ratio**: Select from presets (e.g., `1:1` square `1024x1024`, `16:9` landscape `1344x768`) or custom.
- **width/height**: Custom dimensions (`64–16384`, step `8`) when using custom.
- **swap_dimensions**: Toggle to flip width and height (`Off/On`).
- **batch_size**: Number of latents to generate (`1–64`).
### Outputs
- **empty_latent**: A LATENT tensor (`batch_size x channels x height//8 x width//8`).
- **width/height**: Final dimensions as integers.
### Features
- Automatically rounds dimensions to multiples of `8`.
- Supports preset aspect ratios or custom sizes with dimension swapping.
### Example Usage
Select `SDXL`, `4:3` landscape `1152x896`, and `batch_size=2` to generate two empty latents at `1152x896` for SDXL workflows.

## 🖌️ Prompt Multiple Style Selector (nikosis)
**File:** `nodes/prompt_multiple_styles_selector_nikosis.py`
**Category:** Nikosis/Text
### Description
Combines up to four styles from a `styles.json` file into positive and negative prompts, with dropdown selection.
### Inputs
- **style1/style2/style3/style4**: Choose styles from `styles.json` (defaults to `No Style`).
### Outputs
- **positive_prompt**: Comma-separated positive prompts from selected styles.
- **negative_prompt**: Comma-separated negative prompts from selected styles.
### Configuration
- Requires a `styles.json` file in `config/` (e.g., `comfyui-nikosis-nodes/config/styles.json`).
#### Example `styles.json`
```json
{
"Vivid": {"prompt": "bright colors, high detail", "negative_prompt": "dull, blurry"},
"Minimal": {"prompt": "simple, clean", "negative_prompt": "cluttered"},
}
```
```json
{
"||| PHOTOGRAPHY": {
"prompt": "photography, capturing moments, storytelling, creative composition",
"negative_prompt": "bad anatomy, comics, cropped, cross-eyed, worst quality, low quality, painting, 3D render, drawing,"
},
}
```
- Creates `config/` directory if missing.
### Example Usage
Select `Vivid` and `Minimal` to get:
- **Positive**: `bright colors, high detail, simple, clean`
- **Negative**: `dull, blurry, cluttered`

## 🖌️ Text Concatenate (nikosis)
**File:** `nodes/text_concatenate_nikosis.py`
**Category:** Nikosis/Text
### Description
Concatenates multiple text inputs with a customizable delimiter and optional whitespace cleaning.
### Inputs
- **text_a/text_b**: Required text inputs (must be connected).
- **delimiter**: String to join texts (default: `", "`; supports `\n` for newlines).
- **clean_whitespace**: Toggle to strip extra whitespace (`true/false`).
- **text_c/text_d**: Optional additional texts.
### Outputs
- **STRING**: Concatenated result.
### Features
- Strips whitespace if `clean_whitespace` is `true`.
- Ignores empty inputs.
### Example Usage
**Inputs:**
- `text_a="hello"`
- `text_b="world"`
- `delimiter=" , "`
- `clean_whitespace="true"`
**Output:**
`hello , world`

## Usage Notes
- **Dependencies**: Works with ComfyUI’s standard setup—no extra installs needed.
- **Path**: Place in `ComfyUI/custom_nodes/comfyui-nikosis-nodes/`.
