ardour { ["type"] = "EditorAction", name = "System Exec" } function factory () return function () -- ** EXAMPLES TO RUN EXTERNAL APPLICATIONS ** -- -- run a command in a shell and wait for it to complete. -- -- Details: basically just system(3), except on Unix like systems with -- memory-locking, this call is special-cased to use vfork and close -- file-descriptors. On other systems it defaults to Lua's os-library -- built-in os.execute system() call. os.execute ("date > /tmp/testdate") -- os.forkexec() works as fire-and-forget. execv(3) style -- -- Details: It calls vfork() and exec() under the hood, passing each -- argument separately to exec (and needs a full-path to the binary). os.forkexec ("/usr/bin/xterm") os.forkexec ("/bin/sh", "-c", "import --frame \"/tmp/scr_$(date).png\"") end end
