Abstract
The invention discloses a method for running and graphically analyzing codes in code practicing software. The method includes the steps: 1), compiling a code submitted by a user through a compiler, and returning the code after passing confirmation; 2), generating two results in the process of compiling, wherein the results include a machine language with binary codes and action scope and digital display format information recording variable in the code; 3), starting to simulate each step when the codes run, and extracting state information of each step; 4), encapsulating the state information to be an engine, and providing a jsvascript file including program execution behaviors to a front-end program; 5), decomposing the information for preparation for dsiplay after the front-end program receives the Javascriptjs file; 6), displaying a graphical result through rendering by a browser. By the method, cost for the user to learn the codes is lowered, and principles and steps therein can be sensed while the user uses a high-level language for programming, so that learning effect of the user is improved.
Description
Technical field
The present invention relates to computer programming learning method, especially relate in computer programming process, by the operation of code and patterned parsing are combined, allow user see the change procedure of each step in code operational process and correlated variables, make user better understand principle and the process of programming.。

2) two parts of results are generated in above-mentioned compilation process: one is the machine language of binary code, and portion is the action scope, the digital display format information that record variable in code;
3) start simulation in code each step operating, propose the status information of each step;
4) described status information is packaged into engine, the jsvascript file comprising program act of execution is supplied to Front End;
5) front end receives Jsvascriptjs file, then by information decomposition, ready for showing;
6) eventually pass playing up of browser, demonstrate patterned result.
In step 1, described compilation process comprises the code compilation process based on clang, comprises concrete steps:
1.1) code is submitted to: visitor submits to C code to run debugger to graphical code by front-end edit device automatically;
1.2) Clang lexical analysis and grammatical analysis: call Clang compiler, does morphology and all analyses of plumage to the code submitted to, and generate abstract syntax tree to code generator, generation variable output format and variable enliven block information in file;
1.3) code generator: read in abstract syntax tree from Clang, obtains assembly code, and then generating object file.Comprise variable name and register corresponding relation in assembly code, assembly instruction and code line number corresponding relation etc. meet the Debugging message of DWARF standard;
1.4) linker: read in the file destination that code generator generates, then generate last executable file with existing dynamic link library link.This executable file contains the convenient built-in function following the trail of code implementation of Debugging message and customization.
In step 3, also comprise:
3.1) executable file comprising procedure sign table information is loaded in LLDB process;
3.2) by breakpoint setup in main function position, guarantee that trace information is collected from the first row statement of main function;
3.3) use single step fill order, perform the collection of laggard line program running status in each single step;
3.4) collect the status information that present procedure runs, described status information comprises all values of the variable in action scope, the ruuning situation of call stack, the situation of local variable in the situation of object, the situation of global variable and current function in heap;
3.5) status information of step 3.4 being collected, adopts structurized mode, utilizes the dict dictionary structure in Python to store; If program not yet performs end, repeat the step that single step performs;
3.6) utilize json-dump storehouse, the program state information above-mentioned dictionary structure stored, is saved in text with json form;
3.7) by the json structured data that Json-dump generates, play up code generator through JS, generate the Javascript program code having comprised running state of programs record.
In step 6, comprise further:
6.1) running state of programs recorded information is loaded: by the Javascript load of file of generation in the phase of playing up, be saved in renderer inside in the mode of array;
6.2) one-step program running status is extracted: the single step counting run according to present procedure, extracts corresponding state from array, and gives renderer and play up;
6.3 program states are played up: according to the array content extracted, play up respectively to stack frame, heap space, global variable, pointer adduction relationship.Obtain final display effect.
The cost of user learning code reduces by the present invention, makes user can perception principle wherein and step while using higher level lanquage to carry out programming, and improves the effect of user learning.
