CSharpier vs gofmt

CSharpier is a free, open-source formatter for C# and XML. It parses source files and reprints them using its own formatting rules, with only a few basic options rather than a broad set of style switches. The homepage states support through C# version 14. Configuration can be kept in .csharpierrc JSON or YAML files or in .editorconfig, covering print width, tabs, indentation, and line endings. CSharpier runs as a .NET tool, installed for one project or globally, and CSharpier.Core provides a NuGet API for formatting from code. It can check files and returns a failing exit code by default when formatting is incorrect. Automation options include pre-commit hooks, MSBuild builds, and CI/CD workflows. Integrations are listed for Visual Studio 2022 and 2019, Visual Studio Code, Rider, Neovim, Emacs, and Zed. It runs on Windows, macOS, and Linux. Code that cannot compile produces error diagnostics instead of being formatted.

gofmt is the Go source formatter distributed with Go installations, available on Linux, macOS, and Windows. It formats Go programs using tabs for indentation and spaces for alignment. With no path, it reads standard input; given a directory, it processes .go files recursively while skipping files whose names begin with a period. By default, reformatted source is written to standard output. Flags can show differences, list files that need formatting, apply rewrite rules, simplify code, or report all errors. The rewrite option uses patterns and replacements written as valid Go expressions. gofmt can also arrange documentation comments into canonical paragraphs, lists, headings, links, and code blocks. The Go project documents integrations for Vim, Emacs, Eclipse, and Sublime Text, plus Git pre-commit hooks and Mercurial. Since Go 1.18, it reads and formats files concurrently, with memory use limited in proportion to GOMAXPROCS. The executable is equivalent to go fmt. It is free, included in the Go installation, and distributed under a BSD-style license.
