#process: what a program knows of its own process

import process "gt:process" (or the relative path of the submodule). The package is named tk_process. Pure Odin and the system's own calls, any target.

args := process.command_line_args()     // the arguments without the program's name, as UTF-8
exe := process.executable_path()        // "" when the system cannot say
dir := process.parent_dir(exe)          // "" when the path has no folder; '\' and '/' both separate
process.console_write("done\n")         // the standard output
process.console_error("failed\n")       // the standard error output

On Windows os.args comes from the C runtime's narrow argv, in the system's ANSI code page: a path with a letter outside it arrives damaged. command_line_args reads the UTF-16 command line instead.

A Windows program with a window has no console of its own. console_write writes to the standard output when the parent gave it one (a redirection to a file, a pipe), else to the console of the process that started it, attached once. A redirection is never bypassed.
