What is Biome?

Biome's weekly patches keep widening past JavaScript, with Tailwind the deepest thread.

Biome ships a 2.5.x patch roughly weekly, each carrying a handful of nursery rules and a long tail of formatter and parser fixes. The rule set now reaches well past JavaScript — CSS, HTML, Svelte, Vue, Astro and Tailwind all get attention inside a single release. Type-aware rules remain the expensive part, and their performance is tuned in nearly every patch.

What is metR?

A meteorology ggplot2 extension where the netCDF reader became the main event

metR supplies meteorological and oceanographic tools for R: contour and streamline geoms, EOF decomposition, wave fitting, and ReadNetCDF() for getting gridded data in. Development has concentrated heavily on that reader. Version 0.18.0 added subsetting by dimension index, so the first or last ten timesteps can be read without knowing how many exist; 0.18.1 moved time parsing to the CFtime package; 0.18.2 added cdo operations through rcdo and reading across multiple files in parallel, and fixed a subsetting bug where nearest-gridpoint matching could return data outside the requested range entirely.

Biome's weekly patches keep widening past JavaScript, with Tailwind the deepest thread.

◆ Current state

Biome ships a 2.5.x patch roughly weekly, each carrying a handful of nursery rules and a long tail of formatter and parser fixes. The rule set now reaches well past JavaScript — CSS, HTML, Svelte, Vue, Astro and Tailwind all get attention inside a single release. Type-aware rules remain the expensive part, and their performance is tuned in nearly every patch.

◆ Where it's heading

Two expansions run at once: the languages Biome understands, and the depth of its Tailwind class parser, which has gone from flagging arbitrary values to parsing container-query variants, combinator selectors, bare-utility modifiers and the legacy important marker. Nursery is the staging area, and rules are accumulating there faster than they graduate. The HTML formatter is still absorbing whitespace edge cases, which is where a formatter earns the trust to be run on write.

◆ Prediction

The Tailwind parser work is close to supporting a coherent class sorting and linting story rather than isolated rules, and the nursery backlog will need a graduation pass before the next minor.

A meteorology ggplot2 extension where the netCDF reader became the main event

◆ Current state

metR supplies meteorological and oceanographic tools for R: contour and streamline geoms, EOF decomposition, wave fitting, and ReadNetCDF() for getting gridded data in. Development has concentrated heavily on that reader. Version 0.18.0 added subsetting by dimension index, so the first or last ten timesteps can be read without knowing how many exist; 0.18.1 moved time parsing to the CFtime package; 0.18.2 added cdo operations through rcdo and reading across multiple files in parallel, and fixed a subsetting bug where nearest-gridpoint matching could return data outside the requested range entirely.

◆ Where it's heading

Two threads run through the releases. The first is tracking ggplot2, absorbing the linewidth aesthetic, the trans to transform rename and guide compatibility as each landed upstream. The second is narrowing scope while deepening the data path: GetSMNData() was made defunct as too specific for a general package, raster and gdal dependencies were removed, and the udunits2 dependency was dropped when it was orphaned, initially replaced by a homebrewed date parser and eventually by CFtime. The result is a package steadily shedding its own code in favour of specialised upstream libraries.

◆ Prediction

Expect further ReadNetCDF() work, since it has received features in four of the last five releases and the rcdo integration opens a large surface of operations to expose.
