Ability to check formatting / code style without writing to disk

Hello!

Many existing code formatting tools ( Prettier, ClangFormat ) support checking code format without modifying source files.

Currently to only check formatting I can implement some wrapper which will clone source code, run `dotnet-format’ on this clone and then compare formatted files with original source code. But this seems to be too complex approach for such scenario.

Do you plan to implement feature allowing to check format in dotnet-format (might be a console application option)?..

@jmarolf , thanks for quick response. Sorry, but I didn’t knew that --dry-run option exists, maybe it would help in case above…

Just wondering: will dotnet-format --dry-run -v diag process exit with non-zero exit code if it found files that have to be formatted?

The scenario: I would like to use dotnet-format in continuous integration process or pre-commit git hook so CI build/commit should fail if dotnet-format founds any files that should be reformatted.

@jmarolf thank you, I will open a PR early next week.
