receive_ed

NAME

receive_ed - post-process ed editor output

SYNOPSIS

mixed receive_ed(string msg, string fname) ;

DESCRIPTION

This apply is called to allow post-processing of output from the ed
line editor before it is sent to the user. This is useful for
colorizing, formatting, or otherwise modifying ed's output.

**Arguments:**
- `msg`: The output message from the ed editor
- `fname`: The filename being edited, or 0 if not available

**Return Value:**
- If this apply returns a non-zero value, the driver will not send
  the original message (the mudlib is expected to handle output)
- If this apply returns 0 or is not defined, the driver sends the
  message normally

This apply only works when the `RECEIVE_ED` compile-time option is
enabled in `local_options`. It is typically used with `OLD_ED` mode.

Some error messages still bypass this apply and go directly to output.

EXAMPLE

```c
mixed receive_ed(string msg, string fname) {
    // Colorize ed output
    string colorized = colorize_ed_output(msg);
    receive_message("editor", colorized);
    return 1;  // We handled the output
}
```

SEE ALSO

ed(3), receive_message(4)

NOTE

This apply requires `RECEIVE_ED` to be defined in `src/local_options`
at compile time. By default, this option is disabled.
