Code completion the lower problem of accuracy rate, improve the accuracy rate of code completion.
In the following, will be carried out in conjunction with attached drawing to each step in the method for code completion above-mentioned in this example embodiment detailed
Explanation and explanation.
In step S210, current typing code is parsed to obtain to completion character string, and according to the current record
Enter code to obtain with described to the corresponding function name set of completion character string and attribute-name set.
It should be noted that referring to the currently typing by user to completion character string described in the embodiment of the present invention
Partial character string in code is determined as needing the character string of completion.In this exemplary embodiment, it needs according to current typing generation
Syntax rule the coming out to completion string analysis by current typing code line of the programming language of code.Typically for needing to mend
Complete attribute access, method call code, have the form of " A.B " or " A:B ", wherein A is a complete expression formula name, B
As the attribute-name or method name of a part, B may also be null character string.
Further, it is obtaining after completion character string, it can be according to the context to completion character string in code
Analyze all attribute access (attribute-name set) or method call (function name set) being related to completion character string.Example
Such as, attribute-name and function name set that expression formula A needs to possess can be counted.
In step S230, matched from inquiry in preset dictionary data structure with the function name in the function name set
Target type object, and with the matched target type object of attribute-name in the attribute-name set；Wherein, the dictionary
Data structure includes multiple type objects and attribute-name corresponding with each type object according to history source code building
And function name.
It in this exemplary embodiment, can after obtaining the attribute-name and function name set that above-mentioned expression formula A needs to possess
To use the attribute-name set and function name collection query pre-set dictionary data structure, and then it is possible right to obtain expression formula A
As set (the matched target type object of function name in and function name set, and with the attribute-name in attribute-name set
The target type object matched).It should be added that, in order to improve matching speed, it can need to possess from expression formula A herein
Attribute-name and function name set in, selecting can be with the attribute-name and function name of completion, that is, pre-set dictionary number
It is filtered out according to the attribute-name and function name that may be not present in structure.Specifically, a prefix data tree structure can be prepared,
For each possible object of expression formula A, the attribute name that object is possessed is inserted into the prefix data tree structure.
In step S230, the corresponding objective attribute target attribute name of the target type object is obtained according to the dictionary data structure
With objective function name.
In this exemplary embodiment, when obtaining the matched target type object of the function name in above-mentioned and function name set,
And with after the matched target type object of attribute-name in attribute-name set, further according to dictionary data structure and each target class
Type object obtains corresponding objective function name and objective attribute target attribute name.By this way, the objective function name of acquisition can be improved
With the accuracy of objective attribute target attribute name, and then improve the accuracy of code completion.
In step S240, completion list is formed according to the objective function name and the objective attribute target attribute name, and to institute
Completion list is stated to be shown.
In this exemplary embodiment, code completion graphical interfaces display interface can be called, and passes through code completion figure
Interface display interface shows completion list.Specifically, preamble matching can be done to prefix data tree structure according to word string
It obtains final completion list, then the corresponding code completion graphical interfaces display interface of Integrated Development Environment is called finally to show
To user.
Further, it completes to carry out in current typing code to the part of completion according to completion list for the ease of user
Completion, the method for the code completion can also include: the selection operation in response to user to the completion list, obtain the word
Objective function name corresponding with the selection operation and objective attribute target attribute name in allusion quotation data structure；Utilize the objective function of acquisition
Name and objective attribute target attribute name carry out completion to completion character string to described.
For example, after completion list is shown to user by above-mentioned code completion graphical interfaces display interface, user can be with
According to the actual needs of current typing code, the attribute-name and function name that provide in completion list are selected；Then root
Obtained from pre-set dictionary data structure according to selection result objective function name corresponding with selection operation and with objective attribute target attribute name
It is corresponding, completion is then carried out again.In this way, the accuracy rate of code completion can be improved further；It avoids due to straight
It connected completion list and carries out the case where function caused by completion or attribute codes are not inconsistent with current typing code.
Further, for the ease of from pre-set dictionary data structure to objective function name and to completion attribute-name carry out
Matching, the method for the code completion can also include: to obtain history source code, and the word according to the history source code establishing
Allusion quotation data structure；Wherein, the keyword of the dictionary data structure is function name and attribute-name, the pre-set dictionary data knot
The value of structure is type object corresponding with the function name and the attribute-name.Specifically, refering to what is shown in Fig. 3, according to
Dictionary data structure described in history source code establishing may include step S310- step S320, be described in detail below.
In step s310, the history source code is converted into abstract syntax tree；Wherein, the abstract syntax tree is each
Each syntactic structure in node and the history source code corresponds, the syntactic structure include modular structure, pack arrangement,
Type structure, function structure, valuation structure.
In this exemplary embodiment, it is possible, firstly, to which code library, which is had code (history source code), is converted into abstract syntax
Set (Abstract Syntax Tree), it should be noted that history source code can refer to project in hard disk it is all effectively
Code, current typing code refer to the code just in the file of editor.Specifically, can be led to according to the syntax rule of programming language
It crosses and writes syntax analyzer (Parser) source code text conversion is built into the syntactic structure of tree-shaped form performance, on tree
Each node illustrate one of source code syntactic structure.Wherein, existing source code is in addition to projects to be included
All source code texts used can also include user write, incomplete, even grammer incorrect source generation
Code, for the incorrect code of the possible grammer in this part, syntax analyzer needs to do fault-tolerant processing, as far as possible by wherein most source
Code is converted into abstract syntax tree.
In step s 320, all nodes of the abstract syntax tree are traversed, and according to each in the abstract syntax tree
Set membership between node is and the corresponding node of the modular structure, node corresponding with the pack arrangement and the class
The corresponding node of type structure generates dictionary data structure respectively.
In this exemplary embodiment, firstly, all nodes of whole abstract syntax tree of traversal, obtain module definition node
(Module), package definition node (Package) and class definition node.Specifically, from the root node of abstract syntax tree, time
All nodes for going through whole abstract syntax tree encounter subsequent step definition node to be treated (module definition node, package definition
Node and class definition node) when, corresponding analysis, which is done, using subsequent step handles.Then, according in the abstract syntax tree
Each node between set membership be node corresponding with the modular structure (i.e. module definition node), with the pack arrangement
Corresponding node (i.e. package definition node), node corresponding with the type structure (i.e. class definition node) generate dictionary number respectively
According to structure.Specifically:
For the grammar object (packet, module, class) of support attribute access, need respectively to prepare a dictionary data structure,
The name of the key record syntax object of dictionary data structure, value record syntax object.For example, each package definition node includes
Following information need to record and save: all global objects in dictionary data structure record package definition node, this
The key of a dictionary data structure is the name of global object, and value is global object.According to the syntax rule of programming language, really
Fixed packet and the subordinate relation between attached bag, packet and submodule, attached bag or submodule are also one kind of Bao Nei global object pair.Again
Save for example, the following information that each class definition node includes needs to record: a dictionary structure records the definition of this class
The all properties and function of node, the key of this dictionary data structure are the name of attribute and function, and value is corresponding
Attribute codes or function.
It further, is corresponding with the modular structure according to the set membership between each node in abstract syntax tree
Node and the corresponding node of the pack arrangement, node corresponding with the type structure generate dictionary data structure respectively and may be used also
To include the following two kinds type:
One is, will when determining the corresponding function of the corresponding node of the function structure is the overall situation function of module level
Corresponding modular structure or the corresponding section of pack arrangement is added in the corresponding function name of the overall situation function of the module level and function object
In the dictionary data structure of point；Wherein, the modular structure or the corresponding node of pack arrangement are the corresponding section of the function structure
The father node of point.For example, when the function name for including in determining the class definition node and its corresponding function are overall situation function,
Based on the subordinate relation, the function name and its corresponding function are added to module definition section corresponding with such definition node
In the pre-set dictionary data structure of point.For example, can according to function define where context, find out module level overall situation function or
The method function of class.For the overall situation function of module level, function name is extracted, which is recorded corresponding module (packet)
In global object's dictionary.
Another kind is the section comprising the assignment statement with global namespace in determining the corresponding node of the valuation structure
When point, global object is extracted from the node comprising the assignment statement with global namespace；By the global object and corresponding
Attribute-name and function name are added in the dictionary data structure of corresponding modular structure or the corresponding node of pack arrangement；Wherein, described
Modular structure or the corresponding node of pack arrangement are the father node of the corresponding node of the valuation structure.For example, according to assignment statement
Place context finds out the assignment statement in the assignment statement or class method function of all global namespaces.For global namespace
Assignment statement extracts the name of global object, in global object's dictionary object record to corresponding module (packet).For
Assignment statement in class method function judges that Evaluation node can or can not increase attribute or be set a property for such example, if
Meeting extracts attribute-name, in the attribute dictionary attribute record to respective type.
Fig. 4 schematically shows a kind of from inquiry in preset dictionary data structure and the function name in the function name set
Matched target type object, and the method flow with the matched target type object of attribute-name in the attribute-name set
Figure.Refering to what is shown in Fig. 4, from being inquired in preset dictionary data structure and the matched target of function name in the function name set
Type object, and with the matched target type object of attribute-name in the attribute-name set may include step S410- step
Rapid S430, is described in detail below.
In step S410, inquiry and the function from the dictionary data structure of node corresponding with the modular structure
Name set in the matched target type object of function name and with the matched target class of attribute-name in the attribute-name set
Type object obtains first object type object.
In the step s 420, inquiry and the function name from the dictionary data structure of node corresponding with the pack arrangement
The matched target type object of function name in set and with the matched target type of attribute-name in the attribute-name set
Object obtains the second target type object.
In step S430, inquiry and the function from the dictionary data structure of node corresponding with the type structure
Name set in the matched target type object of function name and with the matched target class of attribute-name in the attribute-name set
Type object obtains third target type object；Wherein, the preset dictionary data structure includes corresponding with the modular structure
The dictionary data structure of node, node corresponding with the pack arrangement dictionary data structure, corresponding with the type structure
Dictionary data structure, the target type object includes the first object type object, the second target type object
And the third target type object.
Hereinafter, remarking additionally to step S410- step S430.Firstly, using module definition node as root node, because
This needs is matched since the pre-set dictionary tree construction of module definition node, obtains above-mentioned first object type object；So
Subordinate relation based on module definition node Yu package definition node afterwards, then from package definition node corresponding with the module definition node
Pre-set dictionary data structure in matched, obtain above-mentioned second target type object；Finally again based on package definition node with
The subordinate relation of class definition node, then from the pre-set dictionary data structure of class definition node corresponding with the package definition node into
Row matching, obtains above-mentioned third target type object.In this way, available more comprehensive completion list, and then make
The objective function name and objective attribute target attribute name that need can be selected according to the completion list by obtaining user, and then to current typing code
To completion part carry out completion, further improve the infull accuracy of code, while reducing the time of developer,
