 デフォルトのローダーとほぼ同じです。LoRAファイルの指定部分がコンボボックスではなくテキストになっているのでSingle Line Pickerを直接繋げることができます。

+「画像を保存」などのファイルを書き出すノードは`filename_prefix(ファイル名_プレフィックス)`パラメータを持ち`%date:%`方式で現在の日付時刻を設定できます。ただしこれはフロントエンドで前処理されるため、実行中の出力と組み合わせることが難しいのです。`filename_prefix`にインプット接続しても日付時刻の処理はされません。
+
+それを解決するためにこのノードでは、日付時刻の処理に加えてプレースホルダによる文字列置き換えを行った結果を出力します。「画像を保存」などの`filename_prefix`に有効な値を渡すことができます。
+
+プレースホルダは`$1` `$2` `$3` `$4`と最大4個作ることができ、それぞれ同名のインプットで置き換えられます。入力は文字列と数値に対応しています。

 It's almost identical to the default loader. Since the LoRA file selection part is text instead of a combo box so that connect a Single Line Picker directly.

It outputs LoRA filename without file extension ([audioscavenger/save-image-extended-comfyui](https://github.com/audioscavenger/save-image-extended-comfyui) can reference LoRA name, but since attempting to reference `lora_name` in the SLP Lora Loader caused an error, the name has been changed to `lora_name_text`.

+It has an output parameter called `stem`. It outputs LoRA filename without file extension. Available in the next section's SLP Filename Prefix.

+### SLP Filename Prefix
+
+Nodes that export files, such as "Save Image" feature a `filename_prefix` parameter that can be set to the current date and time using the `%date:%` format. However, since this is preprocessed by the frontend, it is difficult to combine with backend's runtime output. Connecting an input to `filename_prefix` will not process the date and time.
+
+To resolve this, this node outputs the result of processing the date and time, along with replacing placeholders with strings. You can pass valid value for `filename_prefix` such as "Save Image".
+
+Placeholders can be created up to four: `$1`, `$2`, `$3`, and `$4`. Each is replaced with an input of the same name. Inputs support string and numeric values.
