CHNOSZ vs texor
A side-by-side editorial comparison of CHNOSZ and texor — release velocity, themes, recent moves, and the top alternatives to consider.
CHNOSZ vs texor: at a glance
What is CHNOSZ?
A geochemistry thermodynamics engine that changed its units and its database schema in one release.
CHNOSZ computes thermodynamic properties and phase diagrams for geochemical systems, backed by OBIGT, its bundled thermodynamic database. It releases roughly once a year with a short highlights note pointing at a full changelog elsewhere. Since the 2.0.0 reset, work has been curation and communication: new species in OBIGT, a FAQ vignette, a rewritten introduction, and more readable diagram labels.
What is texor?
The LaTeX-to-R-Markdown converter that stopped transcribing articles and started making them executable.
texor converts legacy R Journal articles from LaTeX into R Markdown, wrestling with the parts that never translate cleanly: numbering, cross-references, algorithm environments, and macros nobody outside the R Journal uses. Since 1.5.0 it can also emit figures as code chunks and tables as CSV read back through kable(), and target bookdown, litedown or biocstyle. The 2025 releases are repair work — pandoc keeps changing underneath it.

CHNOSZ
0.0INFRA · APIS
A geochemistry thermodynamics engine that changed its units and its database schema in one release.
◆ Current state
CHNOSZ computes thermodynamic properties and phase diagrams for geochemical systems, backed by OBIGT, its bundled thermodynamic database. It releases roughly once a year with a short highlights note pointing at a full changelog elsewhere. Since the 2.0.0 reset, work has been curation and communication: new species in OBIGT, a FAQ vignette, a rewritten introduction, and more readable diagram labels.
◆ Where it's heading
2.0.0 was the structural break — Joules replacing calories as the default output of subcrt(), a required E_units column, a new model column, and the removal of a legacy scaling convention for heat-capacity coefficients. Everything since has built on that settled foundation rather than disturbing it. The direction of the last two releases is toward coverage of specific mineral systems, rare earths and uranyl among them, and toward making the package approachable, which suggests a maintainer courting new users rather than reworking the engine.
◆ Prediction
The next release most likely continues OBIGT curation for particular element systems plus vignette work; the highlights format gives no signal of engine-level changes pending.
texor
0.0INFRA · APIS
The LaTeX-to-R-Markdown converter that stopped transcribing articles and started making them executable.
◆ Current state
texor converts legacy R Journal articles from LaTeX into R Markdown, wrestling with the parts that never translate cleanly: numbering, cross-references, algorithm environments, and macros nobody outside the R Journal uses. Since 1.5.0 it can also emit figures as code chunks and tables as CSV read back through kable(), and target bookdown, litedown or biocstyle. The 2025 releases are repair work — pandoc keeps changing underneath it.
◆ Where it's heading
Two expansions define the arc. 1.4.0 took on Sweave as a source format, opening the pre-Rmd back catalogue of literate R documents. 1.5.0 changed what comes out the other end, offering executable code chunks and data files where earlier versions produced flat markup. Both moves point the same way: toward converted articles that still compute rather than merely resemble the original. Everything since has been keeping that machinery working against pandoc's release cadence.
◆ Prediction
The last two releases were both triggered by upstream pandoc changes breaking numbering or Lua filters, so the next release is most likely more of the same; new output styles remain the plausible feature direction given how recently that list was extended.
