Embodiment Construction

[0030] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] The present invention provides a visual code generation method based on the combination of API interface and script definition. The visual program is organized according to levels. The program is composed of several components, and the components are composed of several visual pages. line composition; coordination figure 1 As shown, the process of the present invention is: the front-end processor reads the visualization project file, imports the symbol library, and forms the visualization page data in the memory. Start the script engine, parse and execute the script, call the API interface library in the script, and access the attributes of the symbol. After the script is executed, the backend processor organizes the text paragraphs and outputs the code text.

Abstract

The invention discloses a visualized code generation method based on the combination of an API (application programming interface) and script definition, which is characterized in that visualized programs are hierarchically organized, each program is composed of a plurality of elements, each element is composed of a plurality of visualized pages, and each visualized page is composed of a plurality of graphic symbols and data links. The method comprises the following steps that: a front-end processor reads visualized project files and imports the visualized project files into a symbol library so as to form visualized page data in a memory, starts a script engine, analyzes and executes a script, calls an API library in the script, and accesses the attribute of a symbol; and after the execution of the script is completed, a back-end processor organizes text paragraphs, and outputs a code text. According to the method disclosed by the invention, through using a conventional function of providing a programming platform of the API, the code of a symbol can be defined in a script, so that the dependence on a system software interface is shaken off, and good expansibility is provided for the application personnel; meanwhile, the script can be written, and under the condition of not modifying graphic programs and programming platforms, application scenes can be switched, and then corresponding object codes can be output.

Description

technical field [0001] The invention belongs to the field of visual programming, and in particular relates to a code generation method of a visual graphic program. Background technique [0002] The visual programming platform is a tool for realizing graphical and modular programming based on object-oriented ideas. It calls pre-developed function blocks from symbol library files to build visual page programs, and the programming tools automatically generate codes. Existing code generation methods are often bound to the system software interface, or are limited to a certain application occasion. When the underlying system software interface changes or the application scenario changes, or the application has new requirements, it needs to be modified or redeveloped Code generation tools lack flexibility and versatility. [0003] API (Application Programming Interface, application programming interface) are some predefined functions, the purpose is to provide applications and de...
