Submission

This is a new submission of polyglotSQL 0.1.0.

polyglotSQL provides an R interface to the polyglot-sql Rust crate for parsing, validating, formatting and translating SQL between more than 30 dialects. All computation happens in-process; the package makes no network requests and requires no database, Python or Java runtime.

Test environments

  • local macOS 26 (arm64), R 4.6.0
  • GitHub Actions: ubuntu-latest (R release, R oldrel-1), macOS-latest (R release), windows-latest (R release)
  • win-builder (R-devel)
  • macOS builder (R-release, arm64)

R CMD check results

0 errors | 0 warnings | 1 note

The note is the expected size note for a package with a compiled Rust backend:

* checking installed package size ... NOTE
  installed size is 46.5Mb
  sub-directories of 1Mb or more:
    libs  46.1Mb

The libs directory contains a single shared object with the statically linked Rust engine. The size reflects genuine functionality: the package embeds complete tokenizers, parsers and code generators for 34 SQL dialects, which is the core purpose of the package. The release profile already uses link-time optimization and a single codegen unit; the remaining size is executable code, not debugging information or data.

Rust / compiled code notes

Following the CRAN policy on Rust packages:

  • SystemRequirements declares Cargo (Rust's package manager), rustc >= 1.88.0, xz. That minimum was determined empirically as the maximum rust-version declared by the vendored dependencies and verified by building the package with rustc 1.88.0.
  • All Rust dependencies are vendored in src/rust/vendor.tar.xz, and cargo is invoked with --offline. No code or binary is downloaded during R CMD INSTALL.
  • Compilation is limited to two parallel jobs (cargo build -j 2).
  • configure and configure.win only check for cargo and rustc and print installation instructions; they never install a toolchain.
  • Temporary build artefacts (src/.cargo, the unpacked vendor directory and the cargo target directory) are removed after the build, and cleanup removes the generated src/Makevars.
  • The source tarball contains no compiled binaries.
  • Licenses and copyright of the bundled Rust code, including the upstream Polyglot project (MIT) and the SQLGlot-derived portions (MIT), are recorded in inst/COPYRIGHTS, inst/AUTHORS and Authors@R.
