Helpers for interpolating data into prompts

These functions are lightweight wrappers around glue that make it easier to interpolate dynamic data into a static prompt. Compared to glue, these functions expect you to wrap dynamic values in {{ }}, making it easier to include R code and JSON in your prompt.

Usage

interpolate(prompt, ..., .envir = parent.frame())

interpolate_file(path, ..., .envir = parent.frame())

Arguments

prompt: A prompt string. You should not generally expose this to the end user, since glue interpolation makes it easy to run arbitrary code.
...: Define additional temporary variables for substitution.
.envir: Environment to evaluate ... expressions in. Used when wrapping in another function. See vignette("wrappers", package = "glue") for more details.
path: A path to a prompt file (often a .md).

Value

A {glue} string.

Examples

joke <- "You're a cool dude who loves to make jokes. Tell me a joke about {{topic}}."

# You can supply valuese directly:
interpolate(joke, topic = "bananas")
#> You're a cool dude who loves to make jokes. Tell me a joke about bananas.

# Or allow interpolate to find them in the current environment:
topic <- "applies"
interpolate(joke)
#> You're a cool dude who loves to make jokes. Tell me a joke about applies.
