Completion

Deprecated since version 2.26: Rarely used API

class Completion(*args, **kwargs)

GCompletion provides support for automatic completion of a string using any group of target strings. It is typically used for file name completion as is common in many UNIX shells.

A GCompletion is created using new. Target items are added and removed with add_items, remove_items and clear_items. A completion attempt is requested with complete or complete_utf8. When no longer needed, the GCompletion is freed with free.

Items in the completion can be simple strings (e.g. filenames), or pointers to arbitrary data structures. If data structures are used you must provide a CompletionFunc in new, which retrieves the item’s string from the data structure. You can change the way in which strings are compared by setting a different CompletionStrncmpFunc in set_compare.

GCompletion has been marked as deprecated, since this API is rarely used and not very actively maintained.

Methods

class Completion

clear_items() → None

Removes all items from the Completion. The items are not freed, so if the memory was dynamically allocated, it should be freed after calling this function.

Deprecated since version 2.26: Rarely used API

complete_utf8(prefix: str, new_prefix: str) → list[str]

Attempts to complete the string prefix using the Completion target items. In contrast to complete(), this function returns the largest common prefix that is a valid UTF-8 string, omitting a possible common partial character.

You should use this function instead of complete() if your items are UTF-8 strings.

Added in version 2.4.

Deprecated since version 2.26: Rarely used API

Parameters:

• prefix – the prefix string, typically used by the user, which is compared with each of the items

• new_prefix – if non-None, returns the longest prefix which is common to all items that matched prefix, or None if no items matched prefix. This string should be freed when no longer needed.

free() → None

Frees all memory used by the Completion. The items are not freed, so if the memory was dynamically allocated, it should be freed after calling this function.

Fields

class Completion

cache

The list of items which begin with prefix.

func

Function which is called to get the string associated with a

target item. It is None if the target items are strings.

items

List of target items (strings or data structures).

prefix

The last prefix passed to complete() or

complete_utf8().

strncmp_func

The function to use when comparing strings. Use

set_compare() to modify this function.
