Abstract

The invention discloses a SPEL language-based user-defined identifier dynamic identification and code automatic completion method and system. The method includes the steps of monitoring editing operation of a user on SPEL codes in real time, obtaining and comparing code fragments before and after editing when a cursor leaves a current line, analyzing the changed codes based on a preset SPEL grammar regular expression to identify newly added user-defined identifiers and dynamically adding the newly added user-defined identifiers into a completion library, analyzing the codes before the change to identify the modified or deleted identifiers and removing invalid items from the completion library, and finally providing dynamic and context-related automatic completion prompts based on the updated completion library when the user inputs later. The system comprises a code change monitoring module (1), a difference comparison module (2), a grammar analysis module (3), a code complement library updating module (4) and a code complement prompting module (5). The invention relates to the technical field of industrial robot programming.

Description

SPEL-based user-defined identifier dynamic identification and completion method and system Technical Field The invention relates to an industrial robot programming technology and an internet information service technology, in particular to a method and a system for dynamically identifying and complementing user-defined identifiers based on SPEL (Structured Process Expression Language ). The invention is suitable for Cloud computing-based integrated development environment (Cloud IDE) and Internet code search service, and aims to improve the programming efficiency of a robot engineer through networked and intelligent data processing. Background In industrial robot application development, programming is the core bridge connecting engineers' intentions to machine actions. The industrial robot programming schemes in the current market mainly comprise two major categories, one category adopts mature general programming languages, such as Lua languages adopted by Taida robots and popular robots, and the other category adopts special programming languages independently developed by robot manufacturers, such as SPEL+ languages of the Epson robots, unnamed self-research languages of the sea-health robots and RAPID languages of the ABB robots. The adoption of the universal programming language has the advantages that advanced Integrated Development Environments (IDEs) in the industry such as Visual Studio Code, intelliJ IDEA and the like can be seamlessly connected, powerful intelligent perception (INTELLISENSE) functions are built in the IDEs, accurate automatic code complementation can be provided for user-defined variables, functions and shape parameters of the functions, and development efficiency and code quality are greatly improved. However, for vendors using self-developed proprietary languages, their intelligent capabilities with their mating IDEs tend to be quite weak due to the lack of sophisticated Language Server Protocol (LSP) support and the large community of developers. According to incomplete market research, in mainstream industrial robot products circulated in the market, only tandem robots realize a relatively perfect user-defined identifier complement function in self-research language IDE. The official IDE of the epson robot, which is a main user of the SPEL+ language, can only complement the function names customized by users, and can not provide any prompt for the user-defined variable names which are more basic and have extremely high use frequency and the shape parameter names in the functions. The situation is more severe for the sea robot and ABB robot, and its IDE cannot even complement the user-defined function name. This lack of technology presents a significant hurdle to first-line engineers. In developing large, complex automation projects, engineers need to memorize a large number of self or team member defined variable names, function names, and shape parameter names. Once forgotten, the search must be repeated across multiple code files, which not only severely slows development progress, but also compromises code readability and maintainability. Therefore, a technical solution capable of deeply understanding spel+ language grammar and dynamically identifying and managing user-defined identifiers in real time is needed to fill the gap in the market. Disclosure of Invention The invention aims to overcome the defects in the prior art and provide a SPEL-based user-defined identifier dynamic identification and complementation method and system. The method has the core targets that in the robot IDE, the comprehensive, accurate and real-time code automatic complement function of three key identifiers of a user-defined variable, a user-defined function and a function shape parameter in the SPEL+ programming language environment is realized, so that the technical effects of improving the development efficiency of a robot engineer and enhancing the interactive experience of the SPEL+ language are achieved. The technical scheme adopted by the invention is that the method for dynamically identifying the user-defined identifier and automatically complementing the code based on the SPEL language comprises the following steps: s1, monitoring input or modification operation of a user on SPEL language codes in an integrated development environment in real time; S2, when a user finishes editing a current code line and leaves a cursor from the line, acquiring code fragments before and after the code line is edited, defining the code fragment before the editing as a first code fragment, and defining the code fragment after the editing as a second code fragment; s3, comparing the first code segment with the second code segment to determine changed code content; S4, judging and analyzing the grammar type of the second code segment according to a preset SPEL language grammar regular expression, and identifying a user-defined identifier statement contained in the grammar type; s5, when the user-defined
