A completion item represents a text snippet that is proposed to complete text that is being typed.
Fields
optionaltextEditText:Null<String>
The edit text used if the completion item is part of a CompletionList and CompletionList defines an item default for the text edit range.
Clients will only honor this property if they opt into completion list
item defaults using the capability completionList.itemDefaults
.
If not provided and a list's default range is provided the label property is used as a text.
3.17.0
.optionaltextEdit:Null<EitherType<TextEdit, InsertReplaceEdit>>
An edit which is applied to a document when selecting this completion. When an edit is provided the value of insertText is ignored.
Most editors support two different operation when accepting a completion
item. One is to insert a completion text and the other is to replace an
existing text with a completion text. Since this can usually not
predetermined by a server it can report both ranges. Clients need to
signal support for InsertReplaceEdits
via the
textDocument.completion.insertReplaceSupport
client capability
property.
Note 1: The text edit's range as well as both ranges from a insert
replace edit must be a [single line] and they must contain the position
at which completion has been requested.
Note 2: If an InsertReplaceEdit
is returned the edit's insert range
must be a prefix of the edit's replace range, that means it must be
contained and starting at the same position.

.label:String
The label of this completion item. By default also the text that is inserted when selecting this completion.
optionalkind:Null<CompletionItemKind>
The kind of this completion item. Based of the kind an icon is chosen by the editor.
optionalinsertTextMode:Null<InsertTextMode>
How whitespace and indentation is handled during completion
item insertion. If ignored the clients default value depends on

client capability.

.optionalinsertTextFormat:Null<InsertTextFormat>
The format of the insert text. The format applies to both the
insertText
property and the newText
property of a provided
textEdit
. If omitted defaults to InsertTextFormat.PlainText
.

additionalTextEdits
.
optionalinsertText:Null<String>
A string that should be inserted into a document when selecting
this completion. When falsy
the label
is used.
The insertText
is subject to interpretation by the client side.
Some tools might not take the string literally. For example
VS Code when code complete is requested in this example
con<cursor position>
and a completion item with an insertText
of
console
is provided it will only insert sole
. Therefore it is
recommended to use textEdit
instead since it avoids additional client
side interpretation.
optionalfilterText:Null<String>
A string that should be used when filtering a set of completion items.
When falsy
the label is used.
optionaldocumentation:Null<EitherType<String, MarkupContent>>
A human-readable string that represents a doc-comment.

then type that character.Note* that all commit characters should have length=1
and that superfluous
characters will be ignored.
optionalcommand:Null<Command>
An optional command that is executedafter inserting this completion.Note that additional modifications to the current document should be described with the additionalTextEdits-property.
optionaladditionalTextEdits:Null<Array<TextEdit>>
An optional array of additional text edits that are applied when selecting this completion. Edits must not overlap (including the same insert position) with the main edit nor with themselves.
Additional text edits should be used to change text unrelated to the current cursor position (for example adding an import statement at the top of the file if the completion item will insert an unqualified type).
