PDF Loop

Split a PDF by page and loop thru the pages as both text and images. Each iteration of the loop will populate 3 variables:
pdfLoopPage - the page number
pdfLoopText[0-x] - the text on the page
pdfLoopImage[0-x] - a png image of the page

Parameters

  • file: PDF File

  • pagesPerLoop:

    • text: Pages per loop (create additional variables to do parallel calls inside the loop)
    • min: 1
    • max: 20
    • step: 1
    • default: 1
{{ pdfLoop  | file: "" | pagesPerLoop: 1 }}
Example Usage 1 

{{ variable  | name: "instructions" | value: "Summarize the provided text into 5 concise bullet points that capture the main ideas. Do not include explanations or add any information that isn’t in the original text. Your response should only contain the text itself, formatted appropriately. Do not interpret or explain the content." }}
{{ pdfLoop  | file: "somatosensory.pdf" | pagesPerLoop: "1" }}
{{ LLM  | prompt: "<< name: instructions, prompt: false >>
<< name: pdfLoopText0, prompt: false >>" | cache: "false" }}=>{{ variable  | name: "output" | mode: "append" | value: "" }}
{{ endLoop  }}

<< name: output, prompt: false >>" | cache: "true" }}
Will yield: 
Page 1:
The somatosensory system consists of sensors in the skin, muscles, tendons, and joints.
Cutaneous receptors in the skin provide information about temperature, pressure, texture, and pain.
Receptors in muscles and joints provide information about muscle length, tension, and joint angles.
Meissner corpuscles and rapidly adapting afferents help adjust grip force when lifting objects.
The skin contains various types of mechanoreceptors, both free receptors and encapsulated receptors.

Page 2:
Mammalian muscle spindles have sensory endings that detect stretch and provide feedback for motor control.
Rapidly adapting afferent activity from touch receptors triggers reflexive muscle force increases.
Slowly adapting Merkel's receptors mediate form and texture perception, with higher density in digits and around the mouth.
Pacinian corpuscles detect vibration, while Ruffini corpuscles respond to lateral skin movement or stretching.
Nociceptors are free nerve endings that detect high-threshold mechanical or thermal stimuli as pain.

Page 3:
Rapidly adapting and slowly adapting surface receptors (e.g., hair receptors, Meissner's corpuscle, Merkel's receptor) detect different types of mechanical stimuli.
Deep receptors with large receptive fields (e.g., Pacinian corpuscle, Ruffini's corpuscle) detect diffuse vibrations and skin stretch.
Polymodal receptors respond to intense mechanical, thermal, and chemical stimuli, and transmit pain signals.
Pain signals can be separated into different components (first pain, second pain, deep pain) based on transmission speed and localization.
Muscle spindles are stretch receptors scattered throughout striated muscles, consisting of intrafusal fibers attached to extrafusal fibers.

Condition

Evaluate a condition. If true continue processing the attached chain. If false, break out of the chain and continue to the next node in the flow. Use single quotes around text string to compare them.

Parameters

  • value: A condition to evaluate
{{ condition | value: "1 == 1" }}
Example usage

Example set 1: Basic 

{{ condition  | value: "1 == 1" }}=>This is true!
Will yield the output text: This is true! 
{{ condition  | value: "(5 + 5) == 10" }}=>This is true!
Will yield the output text: This is true! Example set 2: OR, AND 
{{ condition  | value: "OR(1==1, 2==3, 1==2, 1==1)" }}=>This is true!
Will continue the chain and yield the output text: This is true!. 
{{ condition  | value: "AND(1==1, 2==2, 3==3, 4==4)" }}=>This is true!
Will continue the chain and yield the output text: This is true!. 
{{ condition  | value: "OR(1==2,2==3)" }}=>This is true!
Will stop the chain and yield no output, as the chain was blocked with a false condition. Example set 3: Strings 
{{ condition  | value: "'name' == 'name'" }}=>This is true!
Will yield the output text: This is true! 
{{ condition  | value: "CONTAINS('this is a test string', 'test')" }}=>This is true!

{{ condition  | value: "CONTAINS('<< name: variableContainingTest, prompt: false >>', 'test')" }}=>This is true!
Both will yield the output text: This is true! 
{{ condition  | value: "LENGTH('Hello World') > 5" }}=>This is true!
Will yield the output text: This is true! 
{{ condition  | value: "(LENGTH('<< name: variableContainingTest, prompt: false >>') + 12) > 10" }}=>This is true!
Will yield the output text: This is true!
