These functions are lightweight wrappers around glue that make it easier to interpolate dynamic data into a static prompt:
interpolate() works with a string.
interpolate_file() works with a file.
interpolate_package() works with a file in the insts/prompt
directory of a package.
Compared to glue, dynamic values should be wrapped in {{ }}, making it
easier to include R code and JSON in your prompt.
interpolate(prompt, ..., .envir = parent.frame())
interpolate_file(path, ..., .envir = parent.frame())
interpolate_package(package, path, ..., .envir = parent.frame())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.
Environment to evaluate ... expressions in. Used when
wrapping in another function. See vignette("wrappers", package = "glue")
for more details.
A path to a prompt file (often a .md).
Package name.
A {glue} string.
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")
#> [1] │ 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)
#> [1] │ You're a cool dude who loves to make jokes. Tell me a joke about applies.
