项目历史

The official README describes smlfmt as a custom parser and code formatter for Standard ML, fast enough for large projects and used to format its own source tree. The repository release list and README record v1.0.0 in January 2023, v1.2.0 in May 2025, and v1.3.0 in January 2026.

采用历史

The supplied package metadata shows smlfmt packaged in Homebrew and Nix, a typical adoption path for smaller language tooling. Its README targets command-line workflows rather than editor-only integration, including stdin/stdout use, CI-friendly checking, and `.mlb` whole-project formatting.

使用方式

Users build it with MLton, format `.sml` files in place, pipe code through stdin/stdout, or pass an `.mlb` file to format many files. Options include `--preview`, `--preview-only`, `--read-only`, `--check`, width and indentation controls, and SuccessorML syntax toggles.

为什么软件包爱好者会关心

Package maintainers care because smlfmt packages a language-specific formatter with MLton build requirements, command-line formatting semantics, and CI use through `--check`. It fills the same ergonomic role for Standard ML that formatter packages do for larger language ecosystems.
