[0055] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present disclosure. In the detailed description below, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0056] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise," "include," etc. used herein indicate the presence of the features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0057] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0058] When expressions such as “at least one of A, B, and C, etc.” are used, they should generally be interpreted in accordance with the meaning commonly understood by those skilled in the art (e.g., “a system having at least one of A, B, and C” should include but is not limited to systems having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, and C, etc.). When expressions such as “at least one of A, B, or C, etc.” are used, they should generally be interpreted in accordance with the meaning commonly understood by those skilled in the art (e.g., “a system having at least one of A, B, or C” should include but is not limited to systems having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, and C, etc.).

[0059] When developing a program, developers often need to perform keyword searches on the program to retrieve relevant content. For example, keyword searches are required in the following three situations.

[0060] Scenario 1: When a change in field length affects the system, it is necessary to query the entire system code using keywords (field names) to sort out the logic involved.

[0061] For example, in EGL, unlike other programming languages, parameter definitions require not only the type but also the length. Modifying the length of a parameter in one EGL program also requires modifying the length of the corresponding parameter in other EGL programs that call that parameter. Otherwise, the program will generate an error when running.

[0062] Scenario 2: When changes in method logic affect the caller, it is necessary to query the entire system code using keywords (method name) to sort out the logic of calling the method.

[0063] Scenario 3: When expanding the data dictionary for a field, you first need to understand the value assignments for that field in the existing data. In this case, you need to search the entire system code using the keyword (field name), sort through all the assignment statements, and obtain the data dictionary currently used for that field.

[0064] Figure 1 The following schematically shows a search scope diagram of the related art according to an embodiment of the present disclosure.

[0065] like Figure 1 As shown, in the related art, when performing keyword search on an EGL program, the search can only be performed by selecting a relatively rough range, for example, searching for a certain parameter of a certain function.

[0066] In current R&D environments, obsolete code is often handled through comments. This results in a large amount of code content in the system, often represented by multi-line comments such as " / *......* / ". Related keyword search methods do not support filtering these comments. Therefore, when using keyword search methods in related technologies, search results often contain a large number of comments, and the multi-line comments in these comments are difficult to find in the search results, which requires further processing before they can be used.

[0067] On the other hand, when R&D personnel conduct keyword searches, they usually intend to focus only on keywords that exist in a certain grammatical function statement, for example, only on the keyword in the assignment statement. For other grammatical function statements, such as field definitions, field calls, etc., R&D personnel do not need to know whether they contain the keyword.

[0068] Therefore, using the search function in related technologies often does not get the desired results in one go, but requires manual further processing on the search results. When the system is large and the amount of code is large, it often increases the difficulty of subsequent manual sorting and reduces work efficiency. Taking the above three situations as an example, the impact of changes in field length on the system is mainly the impact on assignment statements; changes in method logic have an impact on the system mainly on call statements that need to obtain method return values; and when expanding the data dictionary of fields, the assignment statements also need to be paid attention to. The search method of related technologies will list all statements in the system that use the keyword, corresponding to the specific grammatical functions, which require further manual screening.

[0069] In view of this, embodiments of the present disclosure provide a keyword search method, a keyword search device, an electronic device, a computer-readable storage medium, and a computer program product. The method includes obtaining a search scope, serializing a target program package, retrieving a target keyword, and displaying a target sentence containing the target keyword.

[0070] It should be noted that the keyword retrieval method and device provided by the present disclosure can be used in the financial field, such as banks, and can also be used in any field other than the financial field, such as hospitals. Therefore, the application field of the keyword retrieval method and device provided by the present disclosure is not limited.

[0071] Figure 2 The exemplary system architecture 200 to which the keyword search method according to the embodiment of the present disclosure can be applied is schematically shown. It should be noted that, Figure 2 The examples shown are merely examples of system architectures to which the embodiments of the present disclosure may be applied, to help those skilled in the art understand the technical content of the present disclosure, but do not mean that the embodiments of the present disclosure may not be used in other devices, systems, environments or scenarios.

[0072] like Figure 2 As shown, the system architecture 200 according to this embodiment may include terminal devices 201, 202, 203, a network 204, and a server 205. The network 204 is used as a medium for providing communication links between the terminal devices 201, 202, 203 and the server 205. The network 204 may include various connection types, such as wired and / or wireless communication links, etc.

[0073] Users can use terminal devices 201, 202, and 203 to interact with server 205 via network 204 to receive or send messages, etc. Various communication client applications can be installed on terminal devices 201, 202, and 203, such as web browser applications, search applications, instant messaging tools, email clients, and / or social platform software (for example only).

[0074] The terminal devices 201 , 202 , and 203 may be various electronic devices having a display screen and supporting web browsing, including but not limited to smart phones, tablet computers, laptop computers, and desktop computers.

[0075] Server 205 may be a server that provides various services, such as a background management server (for example only) that supports websites browsed by users using terminal devices 201, 202, and 203. The background management server may analyze and process received data such as user requests, and feed back processing results (e.g., web pages, information, or data obtained or generated according to user requests) to the terminal device.

[0076] It should be noted that the keyword search method provided in the embodiments of the present disclosure can generally be executed by the server 205. Accordingly, the keyword search system provided in the embodiments of the present disclosure can generally be set in the server 205. The keyword search method provided in the embodiments of the present disclosure can also be executed by a server or server cluster that is different from the server 205 and can communicate with the terminal devices 201, 202, 203 and / or the server 205. Accordingly, the keyword search system provided in the embodiments of the present disclosure can also be set in a server or server cluster that is different from the server 205 and can communicate with the terminal devices 201, 202, 203 and / or the server 205.

[0077] It should be understood that Figure 2 The number of terminal devices, networks and servers in the embodiment is merely illustrative. Any number of terminal devices, networks and servers may be provided as required.

[0078] Figure 3 The flowchart of the keyword search method according to the embodiment of the present disclosure is schematically shown.

[0079] like Figure 3 As shown, the keyword search method may include operations S301 to S305.

[0080] In operation S301 , a search scope is acquired, wherein the search scope includes a target program package, a target program file, a target syntax function, and a target keyword.

[0081] In operation S302 , the target package is serialized to obtain at least one target method object.

[0082] In operation S303 , at least one line of target statement is obtained from at least one target method object according to the target grammar function.

[0083] In operation S304 , a target keyword is retrieved from at least one target sentence line.

[0084] In operation S305 , a target sentence including the target keyword is displayed.

[0085] According to embodiments of the present disclosure, the search scope can be specified by the developer. The target method object can be a Function object, and the target statement can be a method statement. Method statements can include, but are not limited to, assignment statements and flow control statements. Syntactic functions can include, but are not limited to, assignment, logical expressions, flow control, method calls, and procedure calls.

[0086] Figure 4 The following schematically shows a schematic diagram of obtaining a target method object according to an embodiment of the present disclosure.

[0087] According to the embodiments of the present disclosure, Figure 4 As shown in the figure, taking the EGL package as an example, based on the selected search scope, starting from the program objects generated by the EGL language parsing system, the method objects used by each program object are determined. The corresponding data structures, such as "Assignment (Evaluation)," "Logical Expression (Expression)," "Flow Control (Flow Control)," "Method Call (Function Call)," and "Program Call (EGL Call)," are found through the method objects.

[0088] According to an embodiment of the present disclosure, each program object corresponds to a target program package. The program object stores method information used by the target program package. The program object can be a Program object. For each method information, the deserialized target method object can search for the target statement corresponding to the grammatical information from the target method object. Then, a keyword search is performed in the target statement based on the target grammatical function within the search range, and the target statement that meets the conditions is displayed, thereby completing the keyword search.

[0089] According to the embodiments of the present disclosure, because a technical means is adopted by obtaining a target statement that can realize the corresponding grammatical function in a method object, then searching for keywords in the target statement, and displaying the retrieved statements containing keywords, it at least partially overcomes the technical problem that when searching for code, the search scope is relatively wide and the desired search results cannot be obtained quickly and accurately, thereby effectively reducing unnecessary information in the search results, and effectively improving the accuracy of the search and work efficiency.

[0090] Figure 5 A flowchart of a method for acquiring a target method object according to another embodiment of the present disclosure is schematically shown.

[0091] According to an embodiment of the present disclosure, each program file of the target program package includes multiple lines of definition statements and at least one method data block; wherein, the multiple lines of definition statements include at least one line of program definition statements and at least one line of method definition statements, and the method data blocks and method definition statements correspond one to one; wherein, each method data block includes at least one line of method statements, and each line of method statements is used to implement a grammatical function.

[0092] Wherein, the target package is serialized to obtain at least one target method object, such as Figure 5 As shown, operations S501 to S505 may be included.

[0093] In operation S501 , for each program file, multiple lines of definition statements are processed to obtain program objects.

[0094] In operation S502 , for each method data block, at least one line of method statement and method definition statement is processed to obtain a method object.

[0095] In operation S503 , a target program object is determined from among the program objects according to the name of the target program file.

[0096] In operation S504, the target program object is parsed to obtain a method linked list, wherein the method linked list includes the name of at least one method data block.

[0097] In operation S505 , at least one target method object is determined from the method objects according to the name of the at least one method data block.

[0098] According to an embodiment of the present disclosure, each program file in the target program package is processed to obtain a program object, and a target program object is determined from the program objects based on the name of the target program file in the search range. The target program object is parsed to obtain a method list.

[0099] According to an embodiment of the present disclosure, a target method object is determined from method objects according to the name of the method data block in the method chain list.

[0100] According to the embodiments of the present disclosure, Figure 4 As shown, processing the definition statement to obtain the program object may include the following operations.

[0101] The strategy chain is used to parse multiple lines of definition statements to obtain multiple program class syntax trees; and the multiple program class syntax trees are serialized to obtain program objects.

[0102] According to the embodiments of the present disclosure, Figure 4 As shown, the policy chain includes multiple program parsers established for program definition statements and method definition statements respectively.

[0103] The following operations may be performed to parse multiple lines of definition statements using a policy chain to obtain multiple program-class syntax trees.

[0104] For each line of definition statement, a plurality of program parsers are used in sequence to identify the definition statement; and the program parser that successfully identifies the definition statement is used to parse the definition statement to generate a program class syntax tree.

[0105] According to an embodiment of the present disclosure, the syntax tree may include a Program syntax tree, a Record syntax tree, a Dataitem syntax tree, a Function syntax tree, an Evaluation syntax tree, an Expression syntax tree, a Flow-control syntax tree, a Function-call syntax tree, and an EGL-call syntax tree, etc., wherein the program-type syntax tree may be a Program syntax.

[0106] According to an embodiment of the present disclosure, the policy chain may include a program parser and a method parser, wherein the program parser may include a Program-define parser, a Record-define parser, and a Dataitem-define parser.

[0107] According to an embodiment of the present disclosure, each line of definition statement is parsed in sequence using multiple program parsers to generate a corresponding program-class syntax tree.

[0108] According to an embodiment of the present disclosure, when multiple program parsers cannot recognize a definition statement, the definition statement is serialized into a persistent object and saved using a specific class.

[0109] According to the embodiments of the present disclosure, Figure 4 As shown, processing at least one line of method statement to obtain a method object may include the following operations.

[0110] At least one line of method statement is parsed using a policy chain to obtain at least one method class syntax tree; and at least one method class syntax tree is serialized to obtain a method object.

[0111] According to the embodiments of the present disclosure, Figure 4 As shown, the policy chain includes multiple method parsers established for each grammatical function.

[0112] Here, using the policy chain to parse at least one line of method statement to obtain at least one method class syntax tree may include the following operations.

[0113] For each line of method statement, a plurality of method parsers are used in sequence to identify the method statement; and the method parser that successfully identifies the method statement is used to parse the method statement to generate a method class syntax tree.

[0114] According to an embodiment of the present disclosure, the method-class syntax tree may be a Function syntax.

[0115] According to an embodiment of the present disclosure, a method parser may include but is not limited to a Function-define parser, an Evaluation parser, an Expression parser, a Flow-control parser, a Function-call parser, and the like.

[0116] According to an embodiment of the present disclosure, each line of method statement is parsed in sequence using multiple method parsers to generate a corresponding method class syntax tree.

[0117] According to an embodiment of the present disclosure, when multiple method parsers cannot identify a method statement, the method statement is serialized into a persistent object and saved using a specific class.

[0118] Figure 6 A flowchart of a method for acquiring a target sentence according to another embodiment of the present disclosure is schematically shown.

[0119] According to the embodiments of the present disclosure, Figure 6 As shown, obtaining at least one line of target statement from at least one target method object according to the target grammar function may include operations S601 to S603.

[0120] In operation S601, at least one target method object is parsed to obtain at least one function linked list.

[0121] In operation S602 , according to the target grammatical function, a function name corresponding to the target grammatical function is acquired from a data dictionary.

[0122] In operation S603, a statement containing a function name is extracted from at least one function chain list to obtain at least one line of target statement of at least one target method object.

[0123] According to an embodiment of the present disclosure, the target method object is deserialized to obtain a corresponding function list, wherein the function list contains the grammatical function of each line of statement, such as assignment and call.

[0124] According to an embodiment of the present disclosure, a function name corresponding to a target grammatical function in a search scope is obtained from a data dictionary, and a statement containing the function name is extracted from a function linked list, the statement being the target statement in the target method object.

[0125] For example, based on the function list's "Evaluation," the function name corresponding to "Evaluation" is obtained from the data dictionary as "CodeEvaluation." This allows multiple target statements containing "CodeEvaluation" to be identified in the function list. For example, one target statement may be "CodeEvaluation-value: A type: 0 alAssignment: 1, alOperator:." A search for the keyword "A" is performed among the multiple statements containing "CodeEvaluation." This identifies "CodeEvaluation-value: A type: 0 alAssignment: 1, alOperator:" as the target statement and displays it. Other statements not containing the keyword "A" are not target statements and are not displayed.

[0126] Figure 7 The block diagram of the keyword search device according to the embodiment of the present disclosure is schematically shown.
