Nodes

---

Text Formatter

Several nodes with varying numbers of optional inputs that can be used

in conjunction with a formatting string to create the output. The node

uses standard [python string formatting][1].

The nodes are useful to compose prompts based on variable inputs and

can be combined with [dynamic prompts][2] for even more flexibility.

Example

Insert values into a string.

Format

"Hello, {arg0}! Did you know? {arg1} is the answer to everything."

Input

arg0: "John"
arg1: 42

Output

"Hello, John! Did you know? 42 is the answer to everything."

Replace Text

Replaces a string in a text with something else, using either plain text

replacement or regular expressions (regex).

Example 1

Replace a word in a text.

Input

text: "Hello, John!"
replace: "John"
replacement: "Mr. Smith"

Output

"Hello, Mr. Smith!"

Example 2

Replace a pattern in a text using regex and use a captured part in the

replacement.

Input

text: "Hello, John! Did you know 42 is the answer to everything?"
replace: "([0-9]+) is"
replacement: "\1 is in fact"

Output

"Hello, John! Did you know 42 is in fact the answer to everything?"
