Use with Dprint
If you already have Dprint, you can skip installing sane-fmt binary. Create a dprint.json file with the following content:
{
"$schema": "https://dprint.dev/schemas/v0.json",
"projectType": "openSource",
"extends": "https://github.com/sane-fmt/sane-fmt/raw/master/exports/sane-fmt.dprint.json",
"includes": [
"**/*.js",
"**/*.ts"
],
"excludes": [
".git",
"node_modules"
],
"plugins": [
"https://plugins.dprint.dev/typescript-${DPRINT_TYPESCRIPT_VERSION}.wasm"
]
}Notes:
- Replace
masterin the"extends"line above with appropriate sane-fmt version. - Replace
${DPRINT_TYPESCRIPT_VERSION}above with appropriate dprint-plugin-typescript version.

sane-fmt --writeThis command would reformat all TypeScript and JavaScript files.
sane-fmtThis command would check all TypeScript and JavaScript files.
sane-fmt --write foo.ts bar.jsThis command would only reformat foo.ts and bar.js.
sane-fmt --write src/This command would reformat all TypeScript and JavaScript files within src/ directory.
Each line of list.txt is a path to a TypeScript/JavaScript file.
sane-fmt --include=list.txtgit ls-files | grep -Ei '\.(js|ts)$' | sane-fmt --include=-sane-fmt also provides a convenient way to integrate with GitHub Actions. To use it, simply add --log-format=github-actions, like so:
sane-fmt --log-format=github-actions --details=diffWhen this command is executed within a GitHub Actions runner, it will:
- Annotates unformatted files.
- Group diffs by file names (if
--details=diff). - Export
total,changed, andunchangedas outputs.
Recommendation: This action will install sane-fmt and execute it for you.
sane-fmt --helpIf you installed sane-fmt via the AUR, completions for bash, fish, and zsh are already installed for you.
Shell completion files are located in ./exports directory of this repo or the Release Page with name in form of completion.<extension> where <extension> is corresponding file extension of target language. Install them to appropriate locations in your filesystem to use.
sane-fmt is an opinionated code formatter for TypeScript and JavaScript powered by dprint. You can think of it as a portable Dprint config file that is always up-to-date.
I want to apply a single, consistent formatting for all my codes regardless of environment without complex tooling.
I have considered using Prettier or Dprint, but that would mean having to set up Node.js even in non-Node.js environments. I also don't like copying my config files back-and-forth to update them.
On the other hand, setting up sane-fmt is simple: just download the binary.
Customization is antithetical to the purpose of this project, and as such, the sane-fmt command does not have customization capability.
However, if you still want a copy of sane-fmt with your own customized rules, do one of the following:
