Method for automatically completing code on basis of LSTM (Long Short Term Memory)

Abstract

The invention provides a method for automatically completing codes on the basis of LSTM (Long Short Term Memory). The method comprises the following steps: performing source code processing, and analyzing source codes by using an abstract grammar tree; performing off-line training, and training a language model by using an LSTM model; performing on-line code completion, and completing codes according to the trained language model. The LSTM model comprises constraint character level LSTM and mark character level LSTM with former context marking character encodes. By adopting the method, automatic code completion can be achieved by inputting any character into any place in the encoding process, recommendation of any code can be also achieved, and the recommendation process accuracy can be also ensured. The technical scheme of the invention has the characteristics of being simple and rapid, and the code recommendation accuracy and the recommendation efficiency can be relatively well improved.

Description

technical field [0001] The invention relates to the technical field of computer software engineering, in particular to a method for automatically completing codes based on LSTM. Background technique [0002] Computer automatic code generation is one of the research hotspots in software engineering in recent years. Automatic code generation greatly reduces the workload of programmers and improves development efficiency. With the development of the open source community, we can generate code by analyzing a large amount of code. A major difficulty in automatic code generation is that the source code itself has many constraints and limitations. In recent years, on the basis of the original research on program synthesis based on combinatorial optimization methods, some new methods for program generation based on machine learning techniques have emerged. [0003] According to different technologies and application scenarios, current program generation methods can be divided int...

However, the disadvantage of this method is that only when the user enters special characters such as ".", the drop-down menu can appear for code completion, and it is impossible to perform code completion or recommendation in any place (for example, when entering any letter); The recommendation in the drop-down menu is only the class name instead of a piece of code, which still cannot be used directly
