To prevent this behavior, a completer can return a RichCompletion with append_closing_quote=False. I.e the completion /usr/bin will turn into /usr/bin". The closing quote will be appended to all completions.cursor at the end of ls "/usr/"), the following happens: When the cursor is appending to a closed string literal (i.e. Use the jedi xontrib to see it in action.Īppend a space after the completion ( append_space=True) Control how the completion looks in prompt-toolkit (via display, description and style).Provide a specific prefix length per completion (via prefix_len) To provide further control over the completion, a completer can return a RichCompletion object. To remove a completer from the list of active completers, runĬompleter remove NAME, where NAME is the unique identifier associated It is also possible to manipulate _xonsh_.completers directly,īut this is the preferred method. To understand how xonsh uses completers and their return values try ''' return, len ( 'lou ' ) + len ( command. # Helper decorators for completers: from import * def dummy_completer ( context ): ''' Completes everything with options "lou" and "carcolh", regardless of the value of prefix. Of the currently-active completers, in the order in which they will beĬompleters are implemented as Python functions that take a Completion Context object.

Order, calling each one in turn and collecting its output until it reaches an exclusive one that returns a non-empty When the “tab” key is pressed, xonsh loops over the completion functions in completions for the built-in commands and/ or). Non-exclusive completers are used for completions that are relevant but don’t cover the whole completions needed The completers are divided to exclusive completers and non-exclusive completers. That maps unique identifiers to completion functions. Xonsh’s built-in completers live in the pleters package, and theyĪre managed through an instance of OrderedDict ( _xonsh_.completers) Includes instructions for implementing new tab completion functions. This page details the internal structure of xonsh’s completion system and Xonsh also provides a mechanism by which the results of a tab completion can beĬustomized (i.e., new completions can be generated, or a subset of the built-in
