🏭 Generators

Interpolated Float List

Generates a list of interpolated float values based on sections.

Input	Type	Description

number_of_sections	INT	Number of sections to divide into
section_number	INT	Current section being processed
interpolation_type	["slinear", "quadratic", "cubic"]	Type of interpolation

Output	Type	Description
floats	FLOAT	List of interpolated float values

Notes: Creates smooth transitions between values using scipy's interpolation.

One Minus Float List

Creates an inverted list of float values (1 - x).

Input	Type	Description
list_of_floats	FLOAT	Input float list

Output	Type	Description
floats	FLOAT	Inverted float values

Notes: Simple inversion operation, useful for creating complementary values.

Remap Float List

Remaps a list of float values from one range to another.

Input	Type	Description
list_of_floats	FLOAT	Input float list
min_input	FLOAT	Minimum input value (default: 0.0)
max_input	FLOAT	Maximum input value (default: 1.0)
min_output	FLOAT	Minimum output value (default: 0.0)
max_output	FLOAT	Maximum output value (default: 1.0)

Output	Type	Description
remapped_floats	FLOAT	Remapped float values

Notes: Useful for scaling values between different ranges while preserving relationships.

Inverse Map Float List

Creates a mirror mapping of float values around their midpoint.

Input	Type	Description
list_of_floats	FLOAT	Input float list

Output	Type	Description
floats	FLOAT	Inverse mapped values

Notes: Automatically determines min/max from input list.

🛠️ Utilities

Int To List Of Bools

Converts an integer into a list of boolean values.

Input	Type	Description
number_of_images	INT	Number to convert

Output	Type	Description
booleans	BOOLEAN	List of boolean values

Notes: Creates a list where first N values are True, rest are False.

List of Ints

Generates a sequential or shuffled list of integers.

Input	Type	Description
min	INT	Starting integer (default: 0)
max	INT	Ending integer (default: 9)
shuffle	BOOLEAN	Whether to randomize order

Output	Type	Description
ints	INT	List of integers

Notes: Output is always a list, even for single values.

Select Index From List

Extracts a single item from a list at the specified index.

Input	Type	Description
list_of_any	any	Input list of any type
index	INT	Index to select (default: 0)

Output	Type	Description
any	any	Selected item

Notes: Uses custom AnyType to accept any input type. Handles tensor unpacking automatically.

Shuffle Image Batch

Randomly reorders images in a batch.

Input	Type	Description
images	IMAGE	Batch of images
seed	INT	Random seed for shuffling

Output	Type	Description
images	IMAGE	Shuffled image batch

Notes: Maintains batch dimensions while randomizing order.

💾 I/O Operations

Save Image To HF Dataset

Uploads images to a HuggingFace dataset.

Input	Type	Description
image	IMAGE	Image to upload
repository_id	STRING	HuggingFace dataset repository
hf_auth_token	STRING	HuggingFace authentication token
filename_prefix	STRING	Prefix for saved files

Notes: Requires HuggingFace authentication token and repository access.

Save EXR Arbitrary

Saves multi-channel data as an OpenEXR file.

Input	Type	Description
channels	any	List of tensor channels
filename_prefix	STRING	Output filename prefix

Notes: Supports arbitrary number of channels. Each channel must have same dimensions.

Save Video To HF Dataset

Uploads video files to a HuggingFace dataset.

Input	Type	Description
filenames	VHS_FILENAMES	List of video files
repository_id	STRING	HuggingFace dataset repository
hf_auth_token	STRING	HuggingFace authentication token
filename_prefix	STRING	Prefix for saved files

Notes: Handles batch upload of multiple video files.

📡 Core Nilor Services

Worker Consumer Service

The worker_consumer.py script is a background service that runs on each ComfyUI worker. It is responsible for pulling jobs from the central ElasticMQ jobs_to_process queue and submitting them to its local ComfyUI instance for processing. This service is essential for the distributed architecture of the system.

Key Responsibilities:

• Continuously polls the jobs_to_process queue for new jobs using long polling.
• When a job is received, it extracts the workflow data and submits it to the local ComfyUI server.
• Deletes the job message from the queue upon successful submission to prevent reprocessing.
• If submission fails, the message remains on the queue to be picked up by another worker.

⚙️ Configuration and Runtime Model

The sidecar uses a small, typed configuration loader with JSON5 defaults and optional environment overrides.

• Precedence: environment variables > config/config.json5 (controlled by allow_env_override: true).
• No hot‑reload: configuration is loaded once at process start and passed to components.
• Paths/keys: JSON5 at ComfyUI/custom_nodes/nilor-nodes/config/config.json5 with NILOR_* keys (e.g., NILOR_COMFYUI_API_URL, NILOR_SQS_ENDPOINT_URL). Secrets (AWS secret) must be set via .env.
• Typed object: loader returns a NilorNodesConfig with comfy and worker sections.

Pseudocode usage:

cfg = load_nilor_nodes_config()
# Comfy endpoints
http_url = cfg.comfy.api_url + "/prompt"
ws_url = cfg.comfy.ws_url + "/ws"
# SQS client params
endpoint = cfg.worker.sqs_endpoint_url
region = cfg.worker.aws_region
access_key = cfg.worker.aws_access_key_id
secret_key = cfg.worker.aws_secret_access_key
client_id = cfg.worker.worker_client_id

Current integrations:

• worker_consumer.py: loads config at startup, reuses a single HTTP session, and uses cfg.comfy/cfg.worker exclusively.
• media_stream.py: uses cfg.worker for SQS completion notifications.

Environment Variables

The nilor-nodes require a .env file to be present in the ComfyUI directory to configure the connection to the core services (MinIO, ElasticMQ, and the Brain API). To set it up, create a file named .env in the root of your ComfyUI directory by copying the .env.example template.

Instructions:

1. Create a new file named .env in the ComfyUI directory.
2. Copy the contents of the .env.example file into your new .env file.
3. Replace the placeholder values with your actual credentials and endpoint URLs for your local or production environment.
