system
use Core.system
The system module provides functions to interact with the system, for example to execute system commands.
| Function Name | Parameter Types | Return Types | Possible Errors |
|---|---|---|---|
system_command | str | i32, str | ErrSystem |
error sets
These are the error sets this Core module provides.
ErrSystem
This error set does not have a parent error, so it directly and only extends anyerror directly. These are the possible values this error could have:
| Error Value | Description |
|---|---|
SpawnFailed | Process could not be created |
system_command
The system_command function executes a given command, for example ls -lah and returns the exit code of the given command together with the output of the command, stored in a string. The function can throw an error if the process (the command) cannot be created.
use Core.print
use Core.system
def main():
(exit_code, output) = system_command("ls");
print($"exit_code = {exit_code}\n");
print($"output = '{output}'\n");
This program will print these lines to the console:
