A graphical page program feature code calculation refresh method

Abstract

The invention discloses a method for calculating and refreshing functional feature codes of graphical page programs. The method comprises the following steps of: respectively defining a static feature code and a dynamic feature code for a page program, and displaying the static feature code and the dynamic feature code in a page header or a page footer area of a graphical page; when the page is opened and initiatively stored, calculating the static feature code and assigning the static feature code to the dynamic feature code; in a page program edition process, obtaining an edition operation triggered by a mouse or a keyboard, immediately calculating a page refreshing dynamic feature code, and when the two feature codes are inconsistent, drawing and displaying the feature codes by adoption of different colors or fonts so as to intuitively identify whether related operations in the page edition process influence the program functions or not; and summarizing each symbol on an energy flow transfer path in which source symbols are input through depth-first traversal, extracting and splicing feature data of each symbol, and carrying out calculation to form an MD5 abstract value or a CRC value to serve as a functional feature code of the graphical page program.

Description

technical field [0001] The invention belongs to the field of graphical programming, and in particular relates to a method for calculating and refreshing graphical page program function feature codes. Background technique [0002] Graphical programming has been widely used in the development of embedded device programs because of its intuition, convenience, and ease of understanding and debugging. Graphical programs are finally converted into text in a certain language, and a compiler is called to form an object code. There are also some new problems in the application process of graphical programming: Due to the requirements of authority management and other aspects, some users do not have the authority to view the source code, so it is impossible to intuitively judge whether the operation modification of the page directly affects the corresponding function code. Some editing operations do not affect the program functions, such as the movement of symbols up, down, left, and...

Problems solved by technology

There are also some new problems in the application process of graphical programming: Due to the requirements of authority management and other aspects, some users do not have the authority to view the source code, so it is impossible to intuitively judge whether the operation modification of the page directly affects the corresponding function code. Some editing operations do not affect the program functions, such as the movement of symbols up, down, left, and right when the connection relationship is not changed, and non-programming-related property modifications. It is necessary to have a feature code that can be associated with the program functions corresponding to the page and remove the impact of non-related modifications.

The existing methods usually statically analyze the imported page file, calculate and extract the CRC of the page, and cannot refresh the display and compare in real time during the page editing process, so an intuitive and simple method is needed to extract and analyze the current page during the page program editing process. Section data, calculate and refresh the feature code of the current program function, and compare and display it with the static feature code opened and saved last time, so that the user can intuitively know whether the current editing operation has modified the corresponding page function code, and dynamically calculate the feature of the page code, requiring fast and accurate calculation methods
