What is lightr?

Reorganised its parsers by vendor, then opened the parser slot to users.

lightr reads spectrometry files from the proprietary formats that instrument vendors ship, and its recent releases have been about the structure of that parser collection rather than adding one more format. Version 2.0.0 renamed every low-level parser from lr_parse_<extension>() to lr_parse_<brand>_<extension>(), a breaking change made specifically so two vendors can share a file extension without colliding, and restored binary parsing for Avantes AvaSoft 8.4 using vendor-supplied format documentation. Version 2.1.0 follows through by exposing a parser argument on the high-level functions.

What is maplegend?

The legend engine mapsf spun out, now covering legend types the parent map package can draw.

maplegend draws the legends for base-R thematic maps, extracted from mapsf so both packages could evolve the legend vocabulary independently. It has been catching up to the map types it has to serve: 0.6.0 added choro_point, choro_line, and choro_symb for choropleth legends rendered on circles, lines, and symbols, following the histogram legend type in 0.4.0. Considerable effort has gone into behaving correctly when the plot aspect ratio is not 1, which required refactoring most of the package in 0.4.0 and still produced a proportional-symbol segment sizing fix in 0.6.3.

Reorganised its parsers by vendor, then opened the parser slot to users.

◆ Current state

lightr reads spectrometry files from the proprietary formats that instrument vendors ship, and its recent releases have been about the structure of that parser collection rather than adding one more format. Version 2.0.0 renamed every low-level parser from lr_parse_<extension>() to lr_parse_<brand>_<extension>(), a breaking change made specifically so two vendors can share a file extension without colliding, and restored binary parsing for Avantes AvaSoft 8.4 using vendor-supplied format documentation. Version 2.1.0 follows through by exposing a parser argument on the high-level functions.

◆ Where it's heading

The package is moving from a fixed set of formats it knows about to a dispatch system users can extend. The brand-qualified naming and the parser argument are two halves of the same design: name parsers unambiguously, then let callers select or supply one. Alongside that runs steady attention to metadata fidelity — measurement timestamps, checksum verification against tampering, and timezone handling that survived upstream tzdata removing legacy codes.

◆ Prediction

Expect additional vendor parsers to arrive under the new brand-qualified scheme, and the custom-parser path to absorb formats the maintainers do not want to support directly. The entries do not name specific instruments planned next.

The legend engine mapsf spun out, now covering legend types the parent map package can draw.

◆ Current state

maplegend draws the legends for base-R thematic maps, extracted from mapsf so both packages could evolve the legend vocabulary independently. It has been catching up to the map types it has to serve: 0.6.0 added choro_point, choro_line, and choro_symb for choropleth legends rendered on circles, lines, and symbols, following the histogram legend type in 0.4.0. Considerable effort has gone into behaving correctly when the plot aspect ratio is not 1, which required refactoring most of the package in 0.4.0 and still produced a proportional-symbol segment sizing fix in 0.6.3.

◆ Where it's heading

This is a support library whose backlog is defined by its caller. Every legend type mapsf can produce needs a matching legend renderer, and the release notes are dominated by spacing, offset, and border details — box_cex for symbol spacing, NA box placement in horizontal choropleth legends, text overflow when no_data is set. The shared vocabulary with mapsf is being maintained deliberately, with val_rnd, val_big, and val_dec propagating through legend types release by release. Version numbering is not monotonic in this feed, with 0.4.0 published seconds after 0.5.0.

◆ Prediction

Expect the remaining combined map types to acquire matching legends and the val_* formatting arguments to reach the types that still lack them.
