説明

Currently, running the formatter (eg via the compiler API: https://github.com/Microsoft/TypeScript/wiki/Using-the-Compiler-API#pretty-printer-using-the-ls-formatter) produces code which is arbitrarily wide, for statements which are nested, complex, etc.

Our style guide requires a maximum columns, which means the formatter should take a configuration for how wide this is. Line breaks should probably be added at the highest point in the AST on the long line.

難度: 4

明確さ: clear
前提条件: TypeScript compilerAST understandingformatter codeNode.js environment
初心者向け度: 25
調査方針: Start by examining the formatting code in the TypeScript compiler, specifically in the src/services/formatting/ directory. Understand how the current formatter works by looking at the 'pretty printer' documentation (https://github.com/Microsoft/TypeScript/wiki/Using the Compiler API#pretty printer using the ls formatter). The 7 comments in the issue may provide additional context or rejected approaches. The goal is to add a configuration option for maximum column width and implement line breaking logic at the highest AST node that exceeds the limit.
