Detailed Description

In order to reduce redundant codes and reduce maintenance cost of project codes when converting type scripts, embodiments of the present application provide a method, an apparatus, and a storage medium for converting code texts. In order to better understand the technical solution provided by the embodiments of the present application, the following brief description is made on the basic principle of the solution:

it should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

The technical scheme provided by the embodiment of the application is described below with reference to the accompanying drawings.

In modern front-end engineering projects, Typescript is increasingly used as a main development language, the Typescript is a static type language and runs by translating into JavaScript, but the JavaScript after translation is a dynamic language, and the type information defined by the Typescript is lost. In a real-world system, data acquired through the outside of the engineering code may not be consistent with types defined in the code (pre-translation type), and in the case that the types are lost in the running code (post-translation JavaScript), verification or type conversion needs to be performed on every place where the type inconsistency may occur.

For example: retrieve parameters from url:

http://www.kuaishou.comgroupNum＝1&tag＝tag1&subquery％5Bcount％5D＝11&subquery％5Bname％5D＝name1；

the groupName, the name, the age and the count are all analyzed into character string types, and because the url specification loses the basic type information of the original field, the parameters need to be manually subjected to type conversion, and at the moment, the scheme can be used for automatically completing the codes of type conversion and assignment according to the types defined by the fields.

In the related art, the retrieval parameters are deserialized into a simple data structure common to the internet, and conversion is performed where the class attribute is used, but since type conversion is performed every time the attribute is used, a large amount of redundant code is caused.

In order to solve the above problems, the present application discloses a code text conversion method, device and storage medium, and the following describes preferred embodiments of the present application with reference to the drawings of the specification, it should be understood that the preferred embodiments described herein are only used for explaining and explaining the present application, and are not used for limiting the present application, and the embodiments and features of the embodiments in the present application can be combined with each other without conflict.

The following further explains the method for converting code text provided in the embodiments of the present application. Referring to fig. 1, the following steps are included.

Step 101: and the electronic equipment analyzes the type script file to obtain an abstract syntax tree of the type script file.

The code text in the application refers to the Typescript class file, that is, the class file formed by adding static type definitions on the basis of JavaScript, and the class file comprises metadata of different structural types.

In order to accurately determine the class file to be converted, the type script class file includes a class file with a mark, and in the implementation process, the electronic device (for example, a computer) can quickly acquire the class file to be converted according to the mark. Note that the flag here can be flexibly set according to the actual operation scenario.

In an implementation process, the electronic device parses the type script class file, for example, the type script class file may be parsed according to a tag of the class file, so as to obtain an abstract syntax tree of the type script class file.

Here, the abstract syntax tree is an abstract representation of the syntax structure of the source code, which represents the syntax structure of the programming language in the form of a tree, and each node on the tree represents a structure in the source code. Namely, the multiple types of the type script class files are obtained in batches through the abstract syntax tree.

For example, when the type of the transcoding includes an array and a structure type, the abstract syntax tree obtained by the electronic device at least includes metadata a with the type of the array and metadata B with the type of the structure, and it is assumed that the parts of the metadata a and the metadata B with the same subscript are data describing different aspects of the same object.

Step 102: and traversing the abstract syntax tree by the electronic equipment to acquire the metadata of the type script file.

In order to quickly acquire the metadata, the electronic device traverses the abstract syntax tree, namely, a complete abstract syntax tree is screened, and because a class constructor, class attributes, a class method and the like are described in the metadata, the electronic device acquires the metadata of the class file with the marks in the type script class file, so that the code text which needs to be converted and simultaneously comprises the type and the assignment can be quickly acquired.

Step 103: the electronic equipment obtains the class attribute and the class constructor recorded in the metadata, and sets a predefined attribute conversion function in the class constructor, wherein the initial data type is recorded in the class attribute.

Metadata related in a front-end engineering project is of an order of magnitude, and in the existing processing mode, when conversion is needed each time, the metadata needs to be manually converted into a target type so as to meet a use scene. For this purpose, in the embodiment of the present application, an attribute conversion function is predefined, and a function of the attribute conversion function may convert the metadata into a corresponding type.

In the implementation process, the storage path of the attribute conversion function is self-defined. That is, in order to determine the conversion function more quickly, the location (i.e., storage path) of the attribute conversion function may be customized. Therefore, after the storage path of the attribute conversion function is customized, the attribute conversion function can be acquired from the customized storage path.

After the attribute conversion function is obtained, an object specifically applying the attribute conversion function needs to be further obtained, and in the implementation process, the electronic device obtains a class attribute and a class constructor recorded in the metadata, wherein the class attribute records an initial data type and inherits specific parameters of the metadata through the class constructor.

For example, the initial data types recorded in the class attribute are examination score of floating point type, student name of character type and student age of integer type, the electronic device acquires examination score A0 and examination score A1 of the array member of metadata A whose type is array by the class constructor, and acquires student name B0, student age B0, student name B1 and student age B1 of metadata B whose type is structure by the class constructor.

Step 104: and the electronic equipment inserts the class attribute into the class constructor for assignment based on the initial data type to obtain the assigned target class attribute.

In the implementation process, specific data is acquired through the class constructor in step 103, but the class attributes are all null, and therefore, the electronic device needs to further assign values to the class constructor. In the assignment process, the electronic device determines an initial data type of the class attribute, namely, performs specific assignment according to the initial data type.

Furthermore, the electronic device inserts the class attribute into the class constructor for assignment, and combines the initial data type, still the above example explains, when the data "B0 zhangsan", "B1 lie si", "B1 12", "B0 11", "a 0 80.5" and "a 1 90.0" are dispersed in the class constructor, the electronic device assigns the class attribute whose assignment is empty according to the initial data type, floating point type, character type and integer type, and obtains the assigned target class attributes of zhangsan, 11 "," 80.5 "," lie si, 12 "and" 90.0 ", respectively. Considering that the parts with the same subscript in the metadata a and the metadata B are assumed to be data for describing different aspects of the same object, the target class attributes may be continued to be integrated to obtain final target class attributes of "zhang san, 11, 80.5" and "lie si, 12, 90.0".

Step 105: the electronic equipment respectively converts the initial data type and the assignment corresponding to the target class attribute based on the attribute conversion function and the preset target data type.

It should be noted that, referring to fig. 2, the step of converting by the electronic device specifically includes:

step 1051: and the electronic equipment determines the attribute conversion function corresponding to the target class attribute in the class constructor according to the corresponding relation between the target class attribute and the attribute conversion function.

Because the number of the parameters of different attributes has large difference, in order to match with the attribute conversion function, the electronic device determines the attribute conversion function corresponding to the target attribute in the class constructor according to the corresponding relationship between the target attribute and the attribute conversion function, wherein the corresponding relationship is bound in advance.

Step 1052: and the electronic equipment assembles the initial data type and assignment corresponding to the target class attribute into a conversion statement according to the format of the attribute conversion function.

In the conversion process, the attribute conversion function includes conversion of the type and assignment of the target class attribute, so that before conversion, the electronic device needs to assemble the initial data type and assignment corresponding to the target class attribute into a conversion statement according to the format of the attribute conversion function.

Still in the above example, considering the initial data type corresponding to the target class attribute, the target class attribute is assembled into the conversion statements of "(str) zhangsan, (int)11, (float) 80.5" and "(str) liqu, (int)12, (float) 90.0" according to the format of the attribute conversion function.

Step 1053: and the electronic equipment inputs the conversion statement into the attribute conversion function for conversion based on the target data type.

In the implementation process, the electronic device converts the initial data type into the target data type through the attribute conversion function, and accordingly, the assignment value is changed through the conversion of the attribute conversion function.

Still in the above example, assuming that the target data types are str, float and int, respectively, the conversion statements "(str) three, (int)11, (float) 80.5" and "(str) lie four, (int)12, (float) 90.0" are input into the attribute conversion function to be converted, and then the converted code statements are "(str) three, (float)11.0, (int) 80" and "(str) lie four, (float)12.0, (int) 90" are obtained.

It should be added that, the attribute conversion function in the above scheme may be implemented in the form of a babel plug-in, so that the plug-in can be configured into a babel configuration file in a project and used.

Referring to fig. 3, a specific application scenario is described below to further detail the above embodiment.

Application scenario 1:

the computer analyzes the type script file A to obtain an abstract syntax tree B of the type script file A, and because the type script file A comprises a plurality of code texts, the code texts which need to be converted can be marked in advance in order to effectively screen out the code texts, and the code texts are supposed to be marked as C. In this way, in the process of traversing the abstract syntax tree B, the metadata C in the type script class file a with the marks can be directly obtained, i.e. the metadata marked as C', C-, etc. are filtered out.

After the metadata C is obtained, the computer continuously extracts the class attribute D and the class constructor E recorded in the metadata, and supposing that the class attribute D is a weather state and the initial type of the weather state is a character type; meanwhile, assuming that the storage path of the attribute conversion function is a D disk, the computer acquires the attribute conversion function from the D disk

Since the class attribute D is directly carried over from the abstract syntax tree B, the assignment of the class attribute D is null, i.e., the "weather state". In order to obtain a specific assignment of the class attribute D, the computer inputs the floating-point type class attribute D with a weather state of null into the class constructor E, wherein it is assumed that when the time is between 6:00 and 12:00, the assigned target class attribute F is a weather state of fine; when the time is between 12:01 and 24:00, the assigned target class attribute F is obtained as 'weather state is negative'; when the time is between 00:01 and 05:59, the assigned target class attribute F is obtained as "weather state ═ rain".

Assuming that the preset target data type is integer, the computer converts "weather state is clear", "weather state is negative", and "weather state is rain", specifically, according to the corresponding relationship between the target class attribute and the attribute conversion function, the attribute conversion function corresponding to the target class attribute in the class constructor is determined, that is, the attribute conversion function is found outNumber of

The computer assembles the initial data type and assignment corresponding to the target class attribute into a conversion statement according to the format of the attribute conversion function, namely, the weather state is clear, the weather state is yin and the weather state is rain according to the format of f (x), so as to obtain the conversion statement

Converting the statement based on the target data type integer
