Formatting

Formatting what you wrote

rose_format applies the repository's own .editorconfig to files you name: indentation, brace placement, line endings, trailing whitespace and the final newline. Call it after writing C# by any other means.

It exists because writing C# and getting its whitespace right are separate skills, and a caller good at the first routinely fails the second — spaces where the repository wants tabs, LF where it wants CRLF. Where IDE0055 is escalated to an error, each of those is a failed build rather than a tidiness question, and the correct answer is not a judgement call: it is written down in a file the compiler already reads.

Two passes, because one is not enough. Roslyn's formatter handles syntax and does honour .editorconfig — measured — but it only rewrites the trivia it has reason to touch, so a four-space, LF-terminated file comes out with tabs and CRLF on the lines it reindented and the original endings everywhere else. The second pass fixes every line. Multi-line verbatim and raw string literals are left exactly as they are, since a newline in one is part of the value and a raw literal's indentation decides how much is stripped from it.

apply=false returns the diff without writing, which makes it a formatting check for a named set of files.
