Abstract. Proper formatting makes the structure of a program apparent and aids program comprehension. The need to format code arises in code generation and transformation, as well as in normal reading and editing situations. Commonly used pretty-printing tools in transformation frameworks provide an easy way to produce indented code that is fairly readable for humans, without reaching the level of purpose-built reformatting tools, such as those built into IDEs. This paper presents a library of pluggable components, built to support style-based formatting and reformatting of code, and to enable further experimentation with code formatting.

“…In addition to the code's size and complexity, the readability of source code can be affected by the identifier names, comments, and overall appearance . This observation led to the invention of prettyprinters , which automatically reformat a source code to improve the appearance or fit a specific coding style. As separate tools or within IDEs, these prettyprinters perform textual transformations such as placing certain kinds of statements on separate lines, indenting and left‐justifying certain lines, inserting blank lines before specific syntactic units such as certain keywords, or removing extra blank space.…”

SUMMARYGood programming practice and guidelines suggest that programmers use both vertical and horizontal spacing to visibly delineate between code segments that represent different algorithmic steps or high-level actions. Unfortunately, programmers do not always follow these guidelines. Editors and integrated development environments (IDEs) can easily indent codes based on syntax, but they do not currently support automatic blank line insertion, which presents more significant challenges involving the semantics.This paper presents and evaluates a heuristic solution to the automatic blank line insertion problem by leveraging both program structure and naming information to identify 'meaningful blocks', consecutive statements that logically implement a high-level action. Our tool, SEGMENT, takes as input a Java method and outputs a segmented version that separates meaningful blocks by vertical spacing. We report on several studies involving human judgments to evaluate the effectiveness of the automatic blank line insertion algorithm, for different size methods and for different levels of programmer expertise. The results indicate strong positive overall opinion of SEGMENT's effectiveness in comparison with both developer-written blank lines and blank lines inserted by newcomers to the code. The results vary only slightly among short and long methods, and among novice and advanced programmers. SEGMENT assists in making users obtain an overall picture of a method's actions and comprehend it quicker as well as provides hints for internal documentation placement.
