Executing Scripts

The purpose of the scriptexec package is to enable quick and easy way to execute native scripts.

library(scriptexec)
library(testthat)

# execute script text
output <- scriptexec::execute("echo command1\necho command2")
expect_equal(output$status, 0)
expect_equal(grepl("command1", output$output), TRUE)
expect_equal(grepl("command2", output$output), TRUE)

if (.Platform$OS.type == "windows") {
    ls_command <- "dir"
} else {
    ls_command <- "ls"
}
output <- scriptexec::execute(c("echo user home:", ls_command))
expect_equal(output$status, 0)

# execute multiple commands as a script
output <- scriptexec::execute(c("cd", "echo test"))
expect_equal(output$status, 0)

# pass arguments (later defined as ARG1, ARG2, ...) and env vars
if (.Platform$OS.type == "windows") {
    command <- "echo %ARG1% %ARG2% %MYENV%"
} else {
    command <- "echo $ARG1 $ARG2 $MYENV"
}
output <- scriptexec::execute(command, args = c("TEST1", "TEST2"), env = c("MYENV=TEST3"))
expect_equal(output$status, 0)
expect_equal(grepl("TEST1 TEST2 TEST3", output$output), TRUE)

# non zero status code is returned in case of errors
expect_warning(output <- scriptexec::execute("exit 1"))
expect_equal(output$status, 1)

# do not wait for command to finish
output <- scriptexec::execute("echo my really long task", wait = FALSE)
expect_equal(output$status, -1)
