range*

A range in a text document expressed as (zero-based) start and end positions. If you want to specify a range that contains a line including the line ending character(s) then use an end position denoting the start of the next line. For example: ```ts { start: { line: 5, character: 23 } end : { line 6, character : 0 } } ``` The Range namespace provides helper functions to work with [Range](#Range) literals.

end*

The range's end position.

character*

Character offset on a line in a document (zero-based). Assuming that the line is represented as a string, the `character` value represents the gap between the `character` and `character + 1`. If the character value is greater than the line length it defaults back to the line length. If a line number is negative, it defaults to 0.

line*

Line position in a document (zero-based). If a line number is greater than the number of lines in a document, it defaults back to the number of lines in the document. If a line number is negative, it defaults to 0.

Try it

A completion item represents a text snippet that is proposed to complete text that is being typed. The CompletionItem namespace provides functions to deal with completion items.

additionalTextEdits

An optional array of additional [text edits](#TextEdit) that are applied when selecting this completion. Edits must not overlap (including the same insert position) with the main [edit](#CompletionItem.textEdit) 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).

detail

A human-readable string with additional information about this item, like type or symbol information.

documentation

A human-readable string that represents a doc-comment.

documentation

filterText

A string that should be used when filtering a set of completion items. When `falsy` the [label](#CompletionItem.label) is used.

insertText

A string that should be inserted into a document when selecting this completion. When `falsy` the [label](#CompletionItem.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.

insertTextFormat

The format of the insert text. The format applies to both the `insertText` property and the `newText` property of a provided `textEdit`.

kind

The kind of a completion entry.

label*

The label of this completion item. By default also the text that is inserted when selecting this completion.

preselect

Select this item when showing. *Note* that only one completion item can be selected and that the tool / client decides which item that is. The rule is that the *first* item of those that match best is selected.

preselect

sortText

A string that should be used when comparing this item with other items. When `falsy` the [label](#CompletionItem.label) is used.

diagnostics

An array of diagnostics known on the client side overlapping the range provided to the `textDocument/codeAction` request. They are provied so that the server knows which errors are currently presented to the user for the given range. There is no guarantee that these accurately reflect the error state of the resource. The primary parameter to compute code actions is the provided range.

Requested kind of actions to return. Actions not of this kind are filtered out by the client before being shown. So servers can omit computing them.
