eric7.DebugClients.Python.FlexCompleter

Word completion for the eric shell.

NOTE for eric variant

This version is a re-implementation of rlcompleter as found in the Python3 library. It is modified to work with the eric debug clients.

Original rlcompleter documentation

This requires the latest extension to the readline module. The completer completes keywords, built-ins and globals in a selectable namespace (which defaults to __main__); when completing NAME.NAME..., it evaluates (!) the expression up to the last dot and completes its attributes.

It's very cool to do "import sys" type "sys.", hit the completion key (twice), and see the list of names defined by the sys module!

Tip: to use the tab key as the completion key, call

readline.parse_and_bind("tab: complete")

Notes:

Global Attributes

Completer (Constructor)

Completer(namespace=None)

Constructor

Completer([namespace]) -> completer instance.

If unspecified, the default namespace where completions are performed is __main__ (technically, __main__.__dict__). Namespaces should be given as dictionaries.

Completer instances should be used as the completion mechanism of readline via the set_completer() call:

readline.set_completer(Completer(my_namespace).complete)

namespace (dict)
namespace for the completer
Raises TypeError:
raised to indicate a wrong data structure of the namespace object

Completer._callable_postfix

_callable_postfix(val, word)

Protected method to check for a callable.

val (Any)
value to check
word (str)
word to amend
Return:
amended word
Return Type:
str

Completer.attr_matches

attr_matches(text)

Public method to compute matches when text contains a dot.

Assuming the text is of the form NAME.NAME....[NAME], and is evaluatable in self.namespace, it will be evaluated and its attributes (as revealed by dir()) are used as possible completions. (For class instances, class members are are also considered.)

WARNING: this can still invoke arbitrary C code, if an object with a __getattr__ hook is evaluated.

text (str)
text to be completed
Return:
list of all matches
Return Type:
list of str

Completer.complete

complete(text, state)

Public method to return the next possible completion for 'text'.

This is called successively with state == 0, 1, 2, ... until it returns None. The completion should begin with 'text'.

text (str)
text to be completed
state (int)
state of the completion
Return:
possible completions
Return Type:
list of str

Completer.global_matches

global_matches(text)

Public method to compute matches when text is a simple name.

text (str)
text to be completed
Return:
list of all keywords, built-in functions and names currently defined in self.namespace that match
Return Type:
list of str
Up


get_class_members

get_class_members(klass)

Module function to retrieve the class members.

klass (Any)
class object to be analyzed
Return:
list of all names defined in the class
Return Type:
list of str
