Represents a prompt template with a template string. The template string can contain placeholders of the form {key}, where key is a sequence of alphanumeric characters and underscores.

Represents a few-shot prompt template with examples. This type allows for creating prompts that include example inputs and outputs, which can be useful for few-shot learning scenarios.

Render a prompt template with the given variables. Returns either an error message if a variable is missing or the rendered template.

Using renderPrompt

To render a prompt template with variables:

let template = PromptTemplate "Hello, {name}! Welcome to {place}."
vars = HM.fromList [("name", Alice), ("place", Wonderland)]
result <- renderPrompt template vars
-- Result: Right "Hello, Alice! Welcome to Wonderland."

If a variable is missing:

let vars = HM.fromList [("name", Alice)]
result <- renderPrompt template vars
-- Result: Left "Missing variable: place"

Render a few-shot prompt template with the given input variables. Returns either an error message if interpolation fails or the fully rendered prompt.

Using renderFewShotPrompt

To render a few-shot prompt template:

let fewShotTemplate = FewShotPromptTemplate
      { fsPrefix = "Examples of {type}:n"
      , fsExamples =
          [ HM.fromList [("input", Hello), ("output", Bonjour)]
          , HM.fromList [("input", Goodbye), ("output", "Au revoir")]
          ]
      , fsExampleTemplate = "Input: {input}nOutput: {output}n"
      , fsExampleSeparator = "n"
      , fsSuffix = "Now translate: {query}"
      }
result <- renderFewShotPrompt fewShotTemplate
-- Result: Right "Examples of {type}:nInput: HellonOutput: BonjournnInput: GoodbyenOutput: Au revoirnNow translate: {query}"
