Detailed Description
In order to reduce redundant codes and reduce project code maintenance cost during type script conversion, the embodiment of the application provides a code text conversion method, a code text conversion device and a storage medium. In order to better understand the technical solution provided in the embodiments of the present application, the basic principle of the solution is briefly described here:
it should be noted that the terms "first," "second," and the like in the description and claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be implemented in sequences other than those illustrated or otherwise described herein. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the accompanying claims.
The following describes the technical scheme provided by the embodiment of the application with reference to the accompanying drawings.
Typescript is used as a main development language in modern front-end engineering projects, and is a static type language and is run by translating into JavaScript, but the translated JavaScript is a dynamic language, so that the type information defined by the Typescript is lost. In real-world systems, data obtained from outside the engineering code may be inconsistent with the types defined in the code (pre-translation Typescript), and in the case that these types are lost in the running code (post-translation JavaScript), it is necessary to check or type-convert everywhere the type inconsistency may occur.
For example: obtaining retrieval parameters from url:
http://www.kuaishou.comgroupNum＝1&tag＝tag1&subquery％5Bcount％5D＝11&subquery％5Bname％5D＝name1；
the groupName, name, age, count is parsed into the character string type, because the url specification has lost the basic type information of the original fields, and the parameters need to be manually type-converted, so that the code for type conversion and assignment can be automatically complemented according to the types defined by the fields by using the scheme.
In the related art, the search parameters are deserialized into a simple internet-generic data structure, and the conversion is performed where the class attribute is used, but since the class conversion is performed every time the attribute is used, a large amount of redundant codes are caused.
In order to solve the above problems, the present application discloses a method, an apparatus and a storage medium for converting code text, and hereinafter, preferred embodiments of the present application are described in conjunction with the accompanying drawings, it should be understood that the preferred embodiments described herein are merely for illustrating and explaining the present application, are not intended to limit the present application, and embodiments of the present application and features of the embodiments may be combined with each other without conflict.
The method for converting the code text provided by the embodiment of the application is further explained below. Referring to fig. 1, the method comprises the following steps.
Step 101: and the electronic equipment analyzes the type script class file to obtain an abstract syntax tree of the type script class file.
The following type script files, namely Typescript files, are introduced first, the code text in the application refers to Typescript files, namely, class files formed by adding static type definitions on the basis of JavaScript, and metadata of different structure types are included in the class files.
In order to accurately determine the class file to be converted, the type script class file includes a class file with a tag, and in an implementation process, an electronic device (e.g., a computer) can quickly acquire the class file to be converted according to the tag. It should be noted that, the marks may be flexibly set according to the actual application scenario.
In the implementation process, the electronic device analyzes the type script class file, for example, the electronic device can analyze the type script class file according to the mark of the class file, so as to obtain an abstract syntax tree of the type script class file.
Here, an abstract syntax tree is an abstract representation of the syntax structure of source code, which represents the syntax structure of a programming language in the form of a tree, each node on the tree representing a structure in the source code. I.e. obtaining multiple types of type script class files in batches through an abstract syntax tree.
For example, when the type of the conversion code includes an array and a structure type, the abstract syntax tree obtained by the electronic device includes at least metadata a of the type array and metadata B of the type of the structure, and it is assumed here that the same subscript in the metadata a and the metadata B is data for describing different aspects of the same object.
Step 102: the electronic equipment traverses the abstract syntax tree to obtain metadata of the type script class file.
In order to quickly acquire metadata, the electronic device traverses the abstract syntax tree, namely, screens the whole abstract syntax tree, and because a class constructor, a class attribute, a class method and the like are described in the metadata, the electronic device acquires the metadata of the class file with the mark in the class script class file, so that code text which needs to be converted and simultaneously comprises types and assignments can be quickly acquired.
Step 103: the electronic device obtains class attributes and class constructors recorded in the metadata, and sets a predefined attribute transfer function in the class constructors, wherein the class attributes have an initial data type recorded therein.
Metadata involved in front-end engineering projects is of the order of magnitude, and in existing processing modes, metadata needs to be manually converted into a target type each time conversion is needed so as to meet a use scene, and in the process, code writing is obviously needed for many times, so that a great deal of redundancy of codes is caused. For this purpose, in the embodiment of the present application, an attribute conversion function is predefined, and the function of the attribute conversion function may convert metadata into a corresponding type.
In the implementation process, the storage path of the attribute conversion function is self-defined. I.e. the location (i.e. the storage path) of the attribute transfer function can be customized in order to make a faster determination of the transfer function. Thus, after the storage path of the attribute conversion function is customized, the attribute conversion function can be obtained from the customized storage path.
After the attribute conversion function is acquired, the object specifically applying the attribute conversion function needs to be further acquired, and in the implementation process, the electronic device acquires the class attribute and the class constructor recorded in the metadata, wherein the class attribute is recorded with the initial data type, and the specific parameters of the metadata are inherited through the class constructor.
For example, the initial data types recorded in the class attribute are a floating point type examination score, a character type student name, and an integer type student age, the electronic device acquires the array member examination score A0 and examination score A1 of the metadata A of the above type array through the class constructor, and acquires the B0 student name, B0 student age, B1 student name, B1 student age of the metadata B of the above type structure through 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, and obtains 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, so that the electronic device needs to further assign a value to the class attributes. In the assignment process, the electronic device determines an initial data type of the class attribute, namely, carries out specific assignment according to the initial data type.
Further, the electronic device inserts the class attribute into the class constructor to perform assignment, and the above example is still described in combination with the initial data type, and when the class constructor is scattered with data of "B0 Zhang Sanzhang", "B1 Liqu", "B1 12", "B0 11", "A0 80.5", "A1 90.0", the electronic device performs assignment for the class attribute with the value being null according to the initial data type floating point type, character type and integer, so as to obtain assigned target class attributes of "Zhang Sanzhan", "11", "80.5", "Liqu, 12" and "90.0", respectively. Considering that the same subscript in the metadata a and the metadata B is the data for describing different aspects of the same object, the object class attributes may be continuously integrated to obtain the final object class attributes of "Zhang san, 11, 80.5" and "Lisi, 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, as shown in fig. 2, the step of converting 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 parameters of different classes of attributes is large in variability, in order to be matched with the attribute conversion function, 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, wherein the corresponding relation is pre-bound, and the attribute conversion function is pre-defined in the class constructor, and after the corresponding attribute conversion function is acquired, the target class attribute is further input into the corresponding attribute conversion function.
Step 1052: and the electronic equipment assembles the initial data type and the 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 comprises conversion of the type and the assignment of the target class attribute, so that before conversion, the electronic equipment needs to assemble the initial data type and the assignment corresponding to the target class attribute into a conversion statement according to the format of the attribute conversion function.
Still referring to the above example, considering the initial data type corresponding to the target class attribute, the target class attribute is assembled into a conversion statement in the format of an attribute conversion function, where the conversion statement is "(str) Zhang san, (int) 11, (float) 80.5" and "(str) Lifour, (int) 12, (float) 90.0".
Step 1053: the electronic device 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 correspondingly, the assignment is changed through the conversion of the attribute conversion function.
Still to explain the above example, assuming that the target data types are str, float, and int, respectively, the converted sentences "(str) Zhang San, (int) 11, (float) 80.5" and "(str) Liqu, (int) 12, (float) 90.0" are input into the attribute conversion function to be converted, and then the converted code sentences are "(str) Zhang San, (float) 11.0, (int) 80" and "(str) Liqu, (float) 12.0, (int) 90".
It should be noted that, the attribute conversion function in the above solution may be implemented in the form of a babel plugin, so that the plugin may be configured into a babel configuration file in an item.
The above embodiments are described in further detail below with reference to fig. 3, which illustrates a specific application scenario.
Application scenario 1:
the computer analyzes the type script class file A to obtain an abstract syntax tree B of the type script class file A, and the type script class file A comprises a plurality of code texts, so that the code texts needing to be converted can be marked in advance for effectively screening out, and the mark is 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 tag can be directly obtained, i.e. the metadata marked as C', C-and the like can be filtered out.
After the metadata C is obtained, the computer continues to extract 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 transfer function is a D disk, the computer reads from the D diskAcquiring attribute transfer functions
Because the class attribute D is directly inherited from the abstract syntax tree B, the class attribute D is assigned a null value, i.e., a "weather state". In order to obtain a specific assignment of the class attribute D, the computer inputs the class attribute D "weather status" of floating point type as null into the class constructor E, where it is assumed that when the time is between 6:00 and 12:00, the assigned target class attribute F is obtained as "weather status=sunny"; when the time is between 12:01 and 24:00, the assigned target class attribute F is 'weather state=negative'; when the time is between 00:01 and 05:59, the assigned target class attribute F is "weather state=rain".
Assuming that the preset target data type is integer, the computer respectively converts weather state=sunny, weather state=cloudy and weather state=rainy, specifically, according to the corresponding relation between the target class attribute and the attribute conversion function, determining the attribute conversion function corresponding to the target class attribute in the class constructor, namely, finding the attribute conversion functionThe computer assembles the initial data type and assignment corresponding to the target class attribute according to the format of the attribute conversion function to form a conversion statement, namely, the weather state=sunny, the weather state=cloudy and the weather state=rainy are assembled according to the format of f (x), so as to obtain the conversion statement ++>Based on the target data type integer, the conversion statement +.>To attribute transfer function->Is converted to obtain conversionAs a result->
