Deploy a typed 'Rserve' app — ts

Writes an 'Rserve' launcher script for an app source file. By default the script is written under the same directory as ts_compile() file output (RserveTS.compile_dir / RSERVETS_COMPILE_DIR / tempdir()) as {basename(f)}.rserve.R. Pass file explicitly to choose another path.

Usage

ts_deploy(
  f,
  file = NULL,
  init = NULL,
  port = 6311,
  run = c("no", "here", "background"),
  silent = FALSE
)

Arguments

f: The path to the application files
file: The file to write the deployment script to. When NULL (default), uses {basename(f)}.rserve.R under the default compile directory (see ts_compile()).
init: Names of ts_function() objects to make available to the initialisation function
port: The port to deploy the app on
run: Whether to run the deployment script, takes values "no", "here", "background"
silent: Whether to print the deployment script

Value

The path written to (file), invisibly. With run = "here" or "background", also starts 'Rserve' as requested.

Examples

src <- tempfile(fileext = ".R")
writeLines(
    "add <- ts_function(function(x = ts_integer(1)) x, result = ts_integer(1), export = TRUE)",
    src
)
out <- ts_deploy(src, silent = TRUE, run = "no")
file.exists(out)
#> [1] TRUE
