r2rtf vs rtflite: at a glance
What is r2rtf?
The clinical-report table engine learned Chinese, then learned to leave RTF entirely
r2rtf builds the RTF tables, listings and figures that go into clinical study reports, and its recent releases have been about widening who and what it can serve rather than changing how tables are composed. The 1.2.0 release added internationalization — a SimSun font path for Chinese characters plus hyphenation control — and 1.3.0 followed with write_docx() and write_html(), turning the LibreOffice conversion the package had documented into exported functions.
What is rtflite?
rtflite stopped being an RTF writer and became the conversion layer for clinical table output.
rtflite generates the RTF tables clinical study reports are built from, a Python answer to the R tooling that has owned this niche. Over one dense month it grew a full export path: DOCX in 2.2.0, DOCX concatenation in 2.3.0, a configurable LibreOffice converter in 2.4.0, and HTML plus PDF in 2.5.0. The three releases since have been documentation, test infrastructure, and typing work — the feature push has stopped and consolidation has started.

The clinical-report table engine learned Chinese, then learned to leave RTF entirely
◆ Current state
r2rtf builds the RTF tables, listings and figures that go into clinical study reports, and its recent releases have been about widening who and what it can serve rather than changing how tables are composed. The 1.2.0 release added internationalization — a SimSun font path for Chinese characters plus hyphenation control — and 1.3.0 followed with write_docx() and write_html(), turning the LibreOffice conversion the package had documented into exported functions.
◆ Where it's heading
Two threads run through the window. One is output reach: RTF remains the composition target, but the artifacts that come out of it now include DOCX and HTML, and page numbering can be made table-relative across multi-page tables. The other is durability under a moving R and font stack — the ANSI/Unicode converter was rebuilt, the LaTeX mapping table generated from code rather than shipped as sysdata, unlist() usage fixed for R 4.5, and graphics-device leaks that produced stray Rplots.pdf closed off.
◆ Prediction
Having exported DOCX and HTML conversion, the likely next step is filling in what those formats lose relative to RTF — pagination and footnote fidelity are the obvious gaps. The i18n path currently covers Chinese only, so additional font families are the other plausible direction.
rtflite
0.0ANALYTICS
rtflite stopped being an RTF writer and became the conversion layer for clinical table output.
◆ Current state
rtflite generates the RTF tables clinical study reports are built from, a Python answer to the R tooling that has owned this niche. Over one dense month it grew a full export path: DOCX in 2.2.0, DOCX concatenation in 2.3.0, a configurable LibreOffice converter in 2.4.0, and HTML plus PDF in 2.5.0. The three releases since have been documentation, test infrastructure, and typing work — the feature push has stopped and consolidation has started.
◆ Where it's heading
Every format addition routes through the same LibreOffice converter rather than a per-format implementation, and 2.4.0's breaking change made that converter an injectable object you can configure and reuse. That is the shape of a package expecting to run inside a pipeline that produces hundreds of tables, not one that converts a document at a time. The recent quiet — snapshot tests moved onto `pytest-r-snapshot`, docs migrated, pandas and pyarrow dropped from dev dependencies — reads as work to stay dependency-light while the surface stabilizes.
◆ Prediction
With the export matrix filled in and three consecutive infrastructure-only releases, the next substantive change is most likely on the input side — table construction and pagination — since `page_by` and `subline_by` are the only feature area still generating bug reports in these notes.
