A completion item represents a text snippet that is proposed to complete text that is being typed.

It is sufficient to create a completion item from just a label. In that case the completion item will replace the word until the cursor with the given label or insertText. Otherwise the the given edit is used.

When selecting a completion item in the editor its defined or synthesized text edit will be applied to all cursors/selections whereas additionalTextEdits will be applied as provided.

    replacing: Range;
}

A range or a insert and replace range selecting the text that should be replaced by this completion item.

When omitted, the range of the current word is used as replace-range and as insert-range the start of the current word to the current position is used.

Note 1: A range must be a single line and it must contain the position at which completion has been requested. Note 2: A insert range must be a prefix of a replace range, that means it must be contained and starting at the same position.
