[0037] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and, together with the description, serve to explain the principles of the present disclosure.

[0043] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0044] In some embodiments, the statically typed programming language TypeScript is a superset of the programming language JavaScript. Since TypeScript provides strong syntax type checking and better code hints, it can help developers find potential errors earlier when writing code and improve the readability and maintainability of the code. At the same time, it also supports the latest ECMAScript standard and provides some additional language features, such as interfaces, enumerations, generics, etc. Therefore, front-end developers usually use TypeScript to develop application interfaces. However, applications implemented using TypeScript consume more storage space and memory resources. For electronic devices with limited resources, such as embedded electronic devices, their hardware capabilities and system capabilities cannot support applications implemented by TypeScript. Therefore, in order to support the same application in electronic devices with limited resources, it is necessary to convert applications implemented using TypeScript into applications implemented using a lightweight programming language, such as converted into applications implemented using the programming language WebAssembly.

[0045] In an exemplary embodiment of the present disclosure, in order to overcome the technical problem that codes of the same programming language are difficult to reuse on electronic devices with different hardware capabilities and system capabilities existing in the related art, a transcoding method is provided, including: determining multiple first code blocks contained in a first code, determining a code generation method of a second code block in a second code according to the code type of the first code block, the second code block having the same code logic as the first code block, wherein the second code is a WebAssembly code, the first code is a type of code other than the WebAssembly code, generating a second code block according to the code generation method of the second code block, and obtaining a second code according to the second code block. The transcoding method converts the first code except the WebAssembly code into the WebAssembly code, so that the first code can be reused on electronic devices with different hardware capabilities and system capabilities, reduces the development difficulty of realizing the same application or the same function in different types of electronic devices, improves development efficiency, and can expand the access applications of electronic devices and enrich the applications supported by electronic devices.

[0046] In an exemplary embodiment of the present disclosure, a transcoding method is provided. Figure 1 is a flowchart of a transcoding method according to an exemplary embodiment. Figure 1 As shown, the following steps are included:

[0047] Step S101, determining a plurality of first code blocks and code types of the first code blocks contained in a first code;

[0048] Step S102, determining a code generation method of a second code block in the second code according to a code type of the first code block, wherein the second code block has the same code logic as the first code block; wherein the second code is a WebAssembly code, and the first code is a type of code other than the WebAssembly code;

[0049] Step S103, generating a second code block according to a code generation method of the second code block;

[0050] Step S104: Obtain a second code according to the second code block.

[0051] The method in the embodiments of the present disclosure is applied to electronic devices, such as smart phones, tablets, personal computers, and other electronic devices with code processing capabilities.

[0052] In step S101, the first code is the code before transcoding, which means the code implemented in the first programming language and can be run on the first electronic device. According to the preset logical rule, the first code is parsed by the parser, and the first code is divided into a plurality of first code blocks. The preset logical rule may be a lexical rule, a grammatical rule, or a semantic rule. The first code is parsed by a lexical parser, a grammatical parser, or a semantic parser, respectively, and the first code block is obtained as a lexical unit, a grammatical unit, or a semantic unit in the first code; the preset logical rule may also be other rules that can divide the code with the same code logic in the first code into one code block.

[0053] The code type of the first code block is determined according to the common code logic of the code in the first code block. For example, when the first code block is a grammatical unit, the code type of the grammatical unit can be an integer, a string, a variable definition, a function, a function block, etc. The code type of the first code block is related to the first code. Different first codes have different code types of the first code blocks. The first code is parsed by a parser, and while the first code is divided into a plurality of first code blocks, the code type of each first code block is determined.

[0054] In step S102, the second code is the transcoded WebAssembly code, which means the code implemented using the second programming language WebAssembly, which has the characteristics of high efficiency, lightness, security and a rich programming language ecology. The first code is other types of code except WebAssembly code, so the first programming language is different from the second programming language.

[0055] In one example, the first code is TypeScript code, that is, code implemented using the programming language TypeScript, and the second code is WebAssembly code, that is, code implemented using the programming language WebAssembly. The first code consumes a lot of storage resources and can run on electronic devices with rich storage resources such as smartphones. The second code consumes less storage resources and can run on resource-constrained embedded electronic devices such as smart watches, and has a rich programming language ecosystem. Converting the first code to the second code can expand the access applications of the device and enrich the applications supported by the electronic device.

[0056] The second code block corresponds to the first code block one-to-one, and the second code block and the first code block have the same code logic. The first code blocks of different code types are converted differently when converted to the second code blocks, that is, the code generation methods of the second code blocks corresponding to the first code blocks of different code types are different. For example, the code generation method of the WebAssembly code block corresponding to the TypeScript code block with the code type of string is: generate a string WebAssembly code block with the same code logic as the TypeScript code block; the code generation method of the WebAssembly code block corresponding to the TypeScript code block with the code type of integer is: generate an integer WebAssembly code block with the same code logic as the TypeScript code block.

[0057] In step S103, after the code generation method of the second code block is obtained, the second code block can be generated according to the code generation method of the second code block, and the generated second code block has the same code logic as the first code block.

[0058] In step S104, all first code blocks in the first code are converted into second code blocks, and all second code blocks are assembled to obtain a second code, and the application or function implemented by the second code is the same as the application or function implemented by the first code.

[0059] In an exemplary embodiment of the present disclosure, by converting multiple first code blocks divided from a first code into second code blocks in a second code respectively, a technical effect of converting other types of code except WebAssembly code into WebAssembly code is achieved, thereby utilizing the efficient, lightweight, secure characteristics of WebAssembly code and a rich programming language ecosystem, so that the first code can be reused on electronic devices with different hardware capabilities and system capabilities, reducing the difficulty of developing the same application or the same function in different types of electronic devices, improving development efficiency, and being able to expand the access applications of electronic devices and enrich the applications supported by electronic devices.

[0060] In an exemplary embodiment of the present disclosure, a transcoding method is provided. Figure 2 is a flowchart of a transcoding method according to an exemplary embodiment. Figure 2 As shown, the following steps are included:

[0061] Step S201, determining a plurality of first code blocks and code types of the first code blocks contained in a first code;

[0062] Step S202, according to the code type of the first code block, matching at least one code generation method of the second code block in the first mapping relationship; wherein the first mapping relationship represents a mapping relationship between the code type of the first code block and at least one code generation method of the second code block, and the second code block has the same code logic as the first code block; the second code is a WebAssembly code, and the first code is a type of code other than the WebAssembly code;

[0063] Step S203, selecting a target code generation method from at least one code generation method;

[0064] Step S204, generating a second code block according to the target code generation method;

[0065] Step S205, assembling multiple second code blocks according to the logical relationship between the multiple first code blocks to obtain a second code.

[0066] The specific implementation of step S201 refers to step S101 and will not be described in detail here.

[0067] In step S202, the code in the first code block has the same code logic, but the same code logic may also include multiple code subtypes. For example, when the code type of the first code block is a variable definition, the variables therein may be variables of different types, and different types of variables correspond to different code generation methods. Therefore, the code type of the first code block corresponds to one or more code generation methods of the second code block. The first mapping relationship represents the mapping relationship between the code type of the first code block and at least one code generation method of the second code block. For example, the first mapping relationship is a mapping relationship table, and Table 1 is an exemplary mapping relationship table. After determining the code type of the first code block, at least one code generation method of the second code block corresponding to the code type of the first code block is matched from the first mapping relationship.

[0068] Table 1

[0069] Code type of the first code block Code generation method for the second code block Type 1 Method 1 Type 2 Method 2, Method 3, Method 4 Type 3 Method 3, Method 5

[0070] In step S203, at least one code generation method of the second code block obtained in the above steps is all code generation methods of the second code block that may correspond to the code type in the first code block, but during conversion, not every code generation method is necessarily required to be used, and the code generation method to be used, i.e., the target code generation method, needs to be determined according to the actual content of the first code block. For example, as shown in Table 1, when the code type of the first code block is type 2, the code generation methods of the second code block include method 1, method 2, and method 3, but these three methods are not necessarily required to be used. If it is determined according to the actual content of the first code block that only method 1 is required, the target code generation method is method 1.

[0071] In some embodiments, the method of selecting a target code generation method from at least one code generation method comprises the following steps:

[0072] S1. Determine a plurality of first sub-code blocks contained in a first code block and a code type of the first sub-code block.

[0073] The first code block further includes a first sub-code block, and the code type of the first sub-code block is a branch of the code type of the first code block. For example, if the code type of the first sub-code block is type 1, and type 1 further includes sub-type 11 and sub-type 12, then the code type of the first sub-code block is sub-type 11 or sub-type 12. The first code block is parsed by a parser, the first code block is divided into a plurality of first sub-code blocks, and the code type of each first sub-code block is obtained.

[0074] S2: According to the code type of the first sub-code block, match the code generation mode of the second sub-code block in the second code block in the second mapping relationship.

[0075] The second mapping relationship represents the mapping relationship between the code type of the first sub-code block and the code generation method of the second sub-code block. After determining the code type of all first sub-code blocks and each first sub-code block contained in the first code block, in the second mapping relationship, the code generation method of the second sub-code block corresponding to the code type of each first sub-code block is matched in turn.

[0076] S3, determining a target code generation method according to the code generation method of the second sub-code block.

[0077] The target code generation mode represents a set of code generation modes of second sub-code blocks corresponding one-to-one to the first sub-code blocks in the first code block, that is, a set of code generation modes of all second sub-code blocks obtained in step S2.

[0078] In an example, as shown in Table 1, the code type of the first code block is type 2, the first code block contains two first sub-code blocks, and the subtypes corresponding to the two first sub-code blocks are subtype 21 and subtype 22 respectively. According to the second mapping relationship, the code generation method of the second sub-code block corresponding to subtype 21 is matched as method 2, and the code generation method of the second sub-code block corresponding to subtype 22 is method 4, then the target code generation method is method 2 and method 4.

[0079] In step S204, a second sub-code block is generated according to the target code generation method, and the second sub-code block has the same code logic as the first sub-code block. All second sub-code blocks are spliced ​​according to the logical relationship between all first sub-code blocks to generate a second code block.

[0080] In step S205, after all second code blocks corresponding to all first code blocks are obtained, multiple second code blocks are assembled according to the logical relationship between the multiple first code blocks to obtain the second code.

[0081] Among them, logical relationships include reference, parallel, selection, condition, etc., which can characterize the dependency relationship between each sub-code block or the dependency relationship between each code block. For example, code block 1 references code block 2, code block 1 and code block 3 are executed in parallel, and code block 4 and code block 5 are executed one by one.

[0082] In some embodiments, the above embodiments further include: obtaining an uncommon first code block in the first code, and modifying the uncommon first code block into a common first code block.

[0083] In order to ensure the accuracy and stability of transcoding, before dividing the first code into multiple first code blocks, an infrequently used first code block in the first code is obtained, that is, a code block with a low usage probability. Infrequently used code blocks are prone to errors during code conversion. Therefore, the infrequently used first code blocks are modified into commonly used first code blocks.

[0084] In an exemplary embodiment of the present disclosure, a transcoding device is provided. Figure 3 is a block diagram of a transcoding device according to an exemplary embodiment. Figure 3 As shown, including:
