Function Documentation

◆ apply_mode_specific_defaults()

void apply_mode_specific_defaults ( options_t * opts )

Apply mode-specific defaults to an options struct after mode detection.

This function updates options that have mode-dependent defaults (port and websocket_port) based on the detected mode. Log file paths are handled separately by options_get_log_filepath().

Parameters

opts	Options struct to update (must have detected_mode already set)

  // Apply port default based on mode
  const int *mode_port = (const int *)get_default_port(opts->detected_mode);

    // Only update if still at a generic default (27224 or 27225)
    if (opts->port == OPT_PORT_INT_DEFAULT || opts->port == OPT_ACDS_PORT_INT_DEFAULT) {
      opts->port = *mode_port;
    }
  }
 
  // Apply websocket-port default based on mode
  const int *mode_websocket_port = (const int *)get_default_websocket_port(opts->detected_mode);
  if (mode_websocket_port) {
    // Only update if still at a generic default (27226 or 27227)
    if (opts->websocket_port == OPT_WEBSOCKET_PORT_SERVER_DEFAULT ||
        opts->websocket_port == OPT_WEBSOCKET_PORT_ACDS_DEFAULT) {
      opts->websocket_port = *mode_websocket_port;

◆ get_default_log_file()

const void * get_default_log_file ( asciichat_mode_t mode )

Get mode-specific default value for –log-file.

Returns empty string - the actual log file path is determined by options_get_log_filepath() which properly handles debug vs release builds and platform-specific temp directories.

Debug builds: Uses current working directory (server.log, client.log, etc.) Release builds: Uses $TMPDIR/ascii-chat/server.log, etc.

  // Return empty string - let options_get_log_filepath() handle the defaults
  return "";
