Parse the output of a Condathis command — parse

This function processes the result of a run() call by parsing the specified output stream ("stdout", "stderr", or "both") into individual, trimmed lines.

Usage

parse_output(res, stream = c("stdout", "stderr", "both", "plain"))

Arguments

res: A list containing the result of run(), typically including stdout and stderr as character strings.
stream: A character string specifying the data stream to parse. Must be either "stdout", "stderr", or "both". Additionally, "plain" can be used to provide raw text as the res input. Defaults to "stdout".

Value

A character vector where each element is a trimmed line from the specified stream.

Examples

# Example result object from condathis::run()
res <- list(
  stdout = "line1\nline2\nline3\n",
  stderr = "error1\nerror2\n"
)

# Parse the standard output
parse_output(res, stream = "stdout")
#> [1] "line1" "line2" "line3"

# Parse the standard error
parse_output(res, stream = "stderr")
#> [1] "error1" "error2"

# Merge both
parse_output(res, stream = "both")
#> [1] "line1"  "line2"  "line3"  "error1" "error2"

# # Parse plain text
plain_text <- "This is line one.\nThis is line two.\nThis is line three."
parse_output(plain_text, stream = "plain")
#> [1] "This is line one."   "This is line two."   "This is line three."
