[0036] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:
[0037] like Figure 5 As shown, a code converter is used to convert one software language into another software language. The code converter includes a preprocessing module 10, a parsing module 20 and a conversion module 30. The preprocessing module 10 is used to preprocess the original code to be converted so that the original code meets the subsequent code parsing specifications after processing. The parsing module 20 is used to parse the preprocessed original code to obtain the information intelligence contained in the original code. The conversion module 30 converts the above-processed original code through a code conversion tool according to the original code information intelligence obtained from the parsing module 20, and outputs a new code. The new code meets the requirements.
[0038] In some preferred embodiments, Figure 5 As shown, the code converter further includes a code shaping module 40, which shapes the new code obtained above and converts it into a code that complies with the new technical framework standard.
[0039] like Figure 1-4 The code conversion method comprises the following steps:
[0040] S100: Process the original code.
[0041] In this step, processing the original code is to preprocess the original code so that the original code meets the subsequent parsing specifications.
[0042] S200, parsing the original code.
[0043] In this step, the preprocessed original code is parsed to obtain information intelligence of the original code.
[0044] S300, conversion code.
[0045] In this step, the original code is converted by a code conversion tool according to the information of the original code obtained, and a new code is output.
[0046] In some preferred embodiments, the steps are further included:
[0047] S400: shaping the new code and outputting it.
[0048] In this step, the new code is shaped to make it fully compliant with the usage standards.
[0049] In some preferred embodiments, the step S100 further includes the following sub-steps:
[0050] S101. Replace the referenced asset content in the original code with the actual asset content.
[0051] In this step, the referenced asset content involved is generally a cpy text, and the code content is updated by replacement.
[0052] S102, replacing the non-standard characters in the original code with standard characters.
[0053] In this step, the characters of the code are standardized by replacing the non-standard characters, which is convenient for subsequent processing. For example, the full-width spaces, TABs, and line breaks that do not conform to the parsing specifications are replaced with regular half-width spaces, TABs, and line breaks, which is the replace operation of the Java string.
[0054] S103: Format the code according to a preset code format.
[0055] In this step, the code formatting process is to adaptively process the original code according to the code format preset by the program configuration, so as to make the format of the original code conform to the standard.
[0056] In some preferred implementations, the original code is parsed by artificial intelligence or by syntax tree. In the parsing step, parsing can be achieved by artificial intelligence or syntax tree.
[0057] In some preferred embodiments, step S200 includes:
[0058] S201. Parse the original code through a parser and convert the original code into an abstract syntax tree.
[0059] In this step, the source code of the current system is parsed into an abstract syntax tree structure through ANTLR4 (ANother Tool for Language Recognition) through a parser. In this way, the abstract syntax tree can be processed through the program to obtain various information intelligence of the current system source code, which is convenient for subsequent processing.
[0060] The syntax tree file (.g4) is generally a standardized associated file of the corresponding development language. For example, for the cobol language, a standard cobol syntax tree file needs to be created first. During the specific implementation, for different specific conversion projects, the adaptability of the standardized syntax tree file will be confirmed first, and then according to the syntax characteristics and development specifications of the original development language, the project engineering code to be adopted will be specially customized to meet the corresponding syntax.
[0061] The syntax tree program part involved is set in the above-mentioned parsing module.
[0062] S202: Decompose the abstract syntax tree in layers.
[0063] In this step, the syntax tree is actually operated. The information of the syntax tree parsed from the current code is obtained. The information of the syntax tree is converted into information that is easy to understand and operate through the core parsing API, which is convenient for subsequent acquisition and use.
[0064] S203: Structuring the information of each layer of the abstract syntax tree and storing it in a syntax container pool.
[0065] In this step, the information of each layer of the syntax tree is structured, and a special syntax container pool is set up in the converter to store the parsed content. Structuring is to store the data of each layer of the abstract syntax tree according to preset rules. In the specific implementation, the obtained information is stored in statements of various syntax types, and the specific content is the decomposed content of each line of syntax. Example: move a to b, decomposed into moveStatement; moveStatement corresponds to a structure of the syntax tree, and its content is two objects, move element and move first; move element stores the content of a; move first stores the content of b.
[0066] The setting of the grammar container pool is the same as that of the grammar tree file. It is first made into a standardized storage, and then customized and modified according to the needs to meet the information storage needs of the grammar tree. The grammar container pool module involved is set in the above-mentioned parsing module.
[0067] In some preferred implementations, in step S300, the conversion code includes:
[0068] S301, obtaining an abstract syntax tree formed after being processed by the parser.
[0069] In this step, the syntax tree generated in step S200 is obtained to facilitate subsequent processing.
[0070] S302: traverse the abstract syntax tree to obtain level information of the syntax tree.
[0071] In this step, information of each level on the syntax tree is further obtained based on the obtained syntax tree.
[0072] S303: Acquire grammatical rules and node information in the hierarchical information and perform matching.
[0073] In this step, the acquired language information is matched with grammatical rules.
[0074] S304, edit the obtained language information and grammar information, and convert them into an Eclipsejdt abstract syntax tree.
[0075] In this step, conversion is performed based on the language information and grammar information, specifically, conversion into an Eclipsejdt abstract syntax tree.
[0076] S305, calling the Eclipsejdt code generation method, and generating converted java source code according to the Eclipsejdt abstract syntax tree.
[0077] In this step, Java code is generated according to the Eclipsejdt code generation method.
[0078] In S300, various syntaxes of the original code are mapped to corresponding converters through the core conversion API to interpret and convert the code.
[0079] The final generated code needs to be shaped, that is, the processing in S400. Specifically, the java code calls the shaping method of eclipseJdt, and the sql part calls the shaping method of sql-formatter.
[0080] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
