# An example for using asciicast, recorded in asciicast itself!      #!

# First, save the R code you want to run, in a script file.          #!
# The file can contain any code, including interactive code,         #!
# as long as it is a syntactically valid R file.                     #!

# Second, perform the recording with the `record()` function.        #!
# We are recording an example file now, that comes with the package. #!

src <- system.file("examples", "hello.R", package = "asciicast")
cast <- asciicast::record(src)

# `cast` is an `asciicast` object, which has some metadata and the   #!
# recording itself:                                                  #!

cast

# You can write `cast` to a JSON file that can be played by any      #!
# asciinema player. Or you can write it to an SVG file that can      #!
# be embedded into a web page, or a GitHub README.                   #!

svg <- tempfile(fileext = ".svg")
asciicast::write_svg(cast, svg, window = TRUE)
