runs source formatters on modified files
Usage: fx format-code [--dry-run] [--verbose] [--all] [--files=FILES,[FILES ...]] [--target=GN_TARGET] [--git] [--changed-lines] [-- PATTERN] --dry-run Stops the program short of running the formatters --all Formats all code in the git repo under the current working directory. --args Formats the configured build's |args.gn| --files Allows the user to specify files. Files are comma separated. Does not support globs. To format all files in a directory, use `cd <dir> && fx format-code --all`. --target Allows the user to specify a gn target. If the template for the given target is defined in a .gni file, the files to format may be forwarded to another target, and specifying the target may not work. The workaround is to pass the target to which the files are forwarded, instead. Specifically, as of January 2023, you can only use this with rustc binary and library targets by appending ".actual" to them. --git The default; it uses `git diff` against the newest parent commit in the upstream branch (or against HEAD if no such commit is found). Files that are locally modified, staged or touched by any commits introduced on the local branch are formatted. --changed-lines Format changed lines only. Only supported on a subset of languages (currently, just C++). Unsupported languages will continue to have the entire file formatted. "Changes" are relative to the git commit that would be used by "--git". --parallel Formats all files in the background rather than waiting on each one before starting the next. WARNING: with this flag enabled, output from multiple formatters may be interleaved, and format-code will exit with status 0 even if some formatters failed. --verbose Print all formatting commands prior to execution. -- PATTERN For --all or --git, passes along -- PATTERN to `git ls-files` to filter what files are affected. For example, to format all rust source files use `fx format-code --all -- "*.rs"` Supported Languages: C, C++, cml, Dart, FIDL, GN, Go, Python, Rust, JSON
