Problems solved by technology

[0004] At present, the commonly used dynamic compilation method in the industry is to formulate DSL specifications according to their own needs and dynamic analysis capabilities, and finally compile the Dart source code into a DSL product, and then the running engine converts the DSL product into page display content in real time, but this The process is very complicated and inefficient

Abstract

The invention provides a dynamic compiling method, device and equipment and a storage medium, belongs to the technical field of computers, and particularly relates to the field of research, development, operation and maintenance of Internet and mobile applications. According to the specific implementation scheme, a DSL specification is used, a source file is analyzed, a DSL syntax tree corresponding to the source file is determined, and a first target file is obtained; and according to the DSL syntax tree, determining a declaration type and a calling sequence of a program object represented by each node, and then according to the declaration type and the calling sequence, determining a loading sequence of the declaration type to obtain a second target file. Due to the fact that the second target file comprises the declaration types of the program objects, the arrangement sequence of which is consistent with the calling sequence, in the process of converting the DSL product in the first target file into the executable file corresponding to the source file in the executable environment, the speed of loading the declaration types and the program objects can be greatly increased; and thus, the efficiency of converting the DSL product into the page display content in real time is improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular, to the field of research and development and operation and maintenance of Internet and mobile applications. Background technique [0002] As flutter technology becomes more and more mature, the technology of online real-time update or hot repair is gradually implemented in some applications (apps), such as the dynamic compilation method of flutter based on the runtime parsing of Domain Specific Language (DSL) products . [0003] DSL is also a computer programming language with language expression ability, but different from General Purpose Language (GPL) such as Java, C, and Python, DSL focuses on a specific field and has limited expression ability, such as displaying web pages. HTML, SQL for database processing, regular expressions for retrieving or replacing text, Gradle for automating builds, etc. [0004] At present, the commonly used dynamic compilation method...
