JSS Style Checker

What JSS Style Checker is

JSS Style Checker checks LaTeX and BibTeX manuscripts against the Journal of Statistical Software style guide. It is available as a command-line tool, Python and R packages, a browser checker, and a VS Code extension. The browser checker accepts .tex, .ltx, .bib, .Rnw, and .Rmd files and processes them locally through WebAssembly; the maker says files stay in the browser tab. Starting with a root file, the linter follows LaTeX input, include, subfile, and bibliography references to inspect the reachable project. Reviewer mode organizes findings into a compliance summary by category, and a GitHub Action can gate JSS-format vignettes in CI. An optional online Crossref lookup checks for missing DOIs and can add them to BibTeX files with --fix. The README reports measured recall and cautions that a clean run does not establish compliance. The project says its distribution channels are MIT-licensed and that it is independent of the journal and publisher. The VS Code extension is described as scaffolded and relies on a language server that has not yet shipped.
