Good code completion can both speed up the development process, as well as aid the developer in API exploration. On the other hand, having a slow or inaccurate completion can be very cumbersome. Thus, it is important to find a way to make it as effective as possible. The current implementation of code completion in the Pharo IDE is based on the abstract syntax tree (AST) of source code. The AST allows us to learn the semantic role and the kind of tokens (e.g. class name, method name, literal, et cetera) and to suggest contextually relevant completions. However, the current implementation has no efficient way to sort the completion candidates, which means that sometimes the user must scroll through a long list of proposed completions to find the one that they need. In this work, I study how code completion can be improved by sorting comple- tions in such a way that most frequently used tokens appear first. To that end, I implement a sorting plugin based on the n-gram language model. I use quantitative and qualitative evaluation techniques to compare the perfor- mance of the n-gram (unigram and bigram) and alphabetic sorters. As a result of the evaluation, the unigram sorter was shown to have the best performance. The sorting strategies implemented are part of a Pharo IDE plugin. It is open source and is available at https://github.com/myroslavarm/CompletionSorting. Додано в НРАТ 2025-11-05 Закрити
