# SRL's nodes

This is a collection of nodes I find useful. Note that at least one
module allows execution of arbitrary code. Do not use any of these
nodes on a system that allow untrusted users to control workflows or
inputs.

# Nodes

## SRL Conditional Interrupt

![Screenshot of SrlConditionalInterrupt](screenshots/SrlConditionalInterrupt.png)

Interrupts the currently running prompt if the "interrupt" input is
true. Also passes through an item of any type for sequencing purposes.

## SRL Format String

![Screenshot of SrlFormatString](screenshots/SrlFormatString.png)

Format a string using Python's string format syntax. You can use both
positional and named argument syntax.

## SRL Eval

![Screenshot of SrlEval](screenshots/SrlEval.png)

Evaluate arbitrary Python code as a function. Do not use on a system
accessible by untrusted users. Code is evaluated as:

```
def func({parameters}):
    code\_line1
    code\_line2
    ...
```

Right now this uses the globals dictionary from the module, so be
careful about anything that might mutate globals, such as importing
modules. I don't have any intention to try to make it secure because
ComfyUI itself isn't remotely secure, but I will probably try to
improve isolation at some point in the future to prevent unintended
problems. PRs gladly accepted if you have need for this.

## SRL Filter Image List

![Screenshot of SrlFilterImageList](screenshots/SrlFilterImageList.png)

Takes a list of images and a list of bools as input and outputs two
image lists, one where the bool is true and the other where it's
false.
