 # ComfyUI-northTools

+This is a collection of nodes I made (some are modified from other nodes) for ComfyUI. If used correctly they can automate a lot your workflow.
+
+## Installation
+
+Just download the zip from this repo and copy it to `ComfyUI/custom_nodes` folder. You can also clone the repo to the same folder.
+
+## Nodes
+
+### 1. Load Image List from Directory
+This node is extracted from ComfyUI-Inspire Pack and edited by me. Other than doing the base things of the original node, it can also, for each image, outputs:
+- `METADATA`: The metadata stored in the image loaded
+- `INDEX_COUNT`: The index of the image in the list
+
+### 2. Extract Metadata value by key
+This node receive an image as input and output a string got from metadata JSON, in the relationship `KEY => Value`. Based on the key, it can output the value of the key stored.
+
+### 3. Sum Integers
+Simple node that sum two integers, no more no less.
+
+### 4. Load Image batch/list from Directory with indexes
+Similar to the load image list from directory node, but instead it also receives a string of indices of images to load.
+Starting from `[0]` for first position, for example `0,2,5,8,15`.
+
+It can output a batch or an image list.
+
+### 5. Boolean list to index string
+Useful for converting booleans to indexes to use with other nodes. Based on positions of booleans, it will convert them to indexes:
+- `TRUE,FALSE,TRUE` -> `0,2` (position 0 is true, position 2 is true)
+
+It accepts formats:
+- `T,F,T`
+- `1,0,1`
+- `true,false,true`
+- `truefalsetrue`
+- `101`
+
+Also: `true / false` are not case sensitive, so it accepts: `TRUE / True / true / T / t`
+
+### 6. Concatenate and remember string
+Useful to remember a value across the various runs. It accepts a boolean to reset the string, otherwise it always concatenate.
+
+### 7. Image to true
+Very simple node that everytime it receive an image, output a true boolean.
