rpymat vs tibblify: at a glance
What is rpymat?
After three dormant years, rpymat returned to fix the OpenMP crash that breaks R and conda together
rpymat manages an isolated conda-based Python environment for R packages, providing a reproducible bridge without touching the user's system Python. It released steadily through 2022-2023 and then went quiet for nearly three years. 0.1.9 in May 2026 is the first release since, and it addresses a specific and long-standing failure mode.
What is tibblify?
tibblify learned to derive its own specs from OpenAPI, removing the step users disliked most
tibblify converts nested lists and JSON into rectangular tibbles using an explicit specification of the expected structure. Its 0.2.0 rewrite moved the engine to C and reset the API; 0.3.1 then added a path to generate specifications from an OpenAPI document rather than hand-writing them. 0.4.0 in May 2026 is the first release in over two years, and it is a breaking cleanup.

After three dormant years, rpymat returned to fix the OpenMP crash that breaks R and conda together
◆ Current state
rpymat manages an isolated conda-based Python environment for R packages, providing a reproducible bridge without touching the user's system Python. It released steadily through 2022-2023 and then went quiet for nearly three years. 0.1.9 in May 2026 is the first release since, and it addresses a specific and long-standing failure mode.
◆ Where it's heading
The work is about surviving the seams between two runtimes. 0.1.9 addresses OpenMP double-initialization — the error users hit when R's OpenMP and conda's disagree — by setting KMP_DUPLICATE_LIB_OK as a compromise, and adds fix_omp_conflict() to symlink over conda's built-in version as the recommended real fix. The caveat is stated plainly: users must re-run it whenever R is updated, and the ABI versions must match. Earlier releases followed the same pattern, with 0.1.2 fixing segfaults from incompatible BLAS between numpy and R.
◆ Prediction
The recurring theme across releases is native library conflicts between the R and conda stacks, so further releases are likely to keep patching that surface as Python versions move. The three-year gap makes cadence unpredictable.

◆ Current state
tibblify converts nested lists and JSON into rectangular tibbles using an explicit specification of the expected structure. Its 0.2.0 rewrite moved the engine to C and reset the API; 0.3.1 then added a path to generate specifications from an OpenAPI document rather than hand-writing them. 0.4.0 in May 2026 is the first release in over two years, and it is a breaking cleanup.
◆ Where it's heading
The arc runs from 'write a spec by hand' toward 'the spec comes from somewhere else'. Alongside the OpenAPI importer, guess_tspec() gained exported variants so users can override its dispatch, and untibblify() now picks up the tib_spec attribute automatically. 0.4.0's breaking change prefixes all arguments of dot-accepting functions with a period to avoid collisions with column names, softened by a once-per-session deprecation warning, and refactors the entire codebase.
◆ Prediction
The un-dotted argument forms are explicitly slated for removal, so the next release most likely completes that deprecation. Whether the 0.4.0 refactor introduced corner-case regressions is the open question the release notes themselves raise.
