The goal of this pack is to keep genuinely useful glue nodes in one place without pulling in a large third-party custom-node bundle just to get one tiny piece of functionality.

Included

`Text Split (Delimiter)`

Splits an input string using a delimiter and returns:

part_1 through part_20
remainder
count

Behavior:

output_count controls how many leading parts are emitted before overflow is collected into remainder
strip_parts trims whitespace around each part
skip_empty removes empty parts after splitting
delimiter supports common escape strings such as \n, \r\n, \r, and \t

This node intentionally uses a fixed socket layout instead of dynamic outputs so saved workflows stay predictable and easy to debug.

`Lazy Index Switch`

Selects one of input_0 through input_19 using a zero-based index value.

Behavior:

accepts any ComfyUI type on its input sockets
evaluates only the selected input branch
pairs with combo-style nodes that expose an INDEX output
reports a clear validation error if the selected input is not connected

`Enviral Image Resize Kit`

Resizes an image with a small set of explicit workflow-friendly modes:

pass-through: keeps the input image resolution and ignores width/height
explicit resize: stretches the image to the requested width and height
inside fit: preserves the full image, pads to the requested aspect ratio, then outputs the requested width and height
outside fit: fills the requested aspect ratio and center-crops overflow

The mode input is a dropdown, but it also accepts linked strings such as resize, pad, crop, and pass-through. This makes it pair cleanly with combo nodes that output strings. Optional masks are transformed with the same geometry and the node returns image, width, height, and mask.

`LM Studio Unified (URL + API Key)`

Sends text, an image, or both to an LM Studio OpenAI-compatible chat endpoint.

Inputs:

base_url: accepts http://127.0.0.1:1234/v1, https://lmstudio.example.com, or a full /v1/chat/completions URL
api_key: optional bearer token for LM Studio API-token auth
api_key_env_var: optional environment variable fallback when api_key is blank, defaulting to LMSTUDIO_API_KEY. On Windows, this checks the current process first, then the User and Machine environment variable registry values.
model, prompt, system_prompt, seed, max_tokens, temperature, and timeout_seconds
optional image input for vision-capable models. If the input is an IMAGE batch, each frame is sent as a separate image_url content part, capped by max_images

For a secured Cloudflare route, use a public base_url such as:

https://lmstudio.enviral-design.com

The node will call:

https://lmstudio.enviral-design.com/v1/chat/completions
