Changelog • blockr.ggplot

blockr.ggplot (development version)

The blocks use blockr.ui for their controls and tokens, and no longer import blockr.dplyr. The vendored settings-band and DrilldownConfig copies are gone; their unscoped rules restyled every gear tray on a board.
ggplot block: chart-type tiles and the mapping stay on the face, the tiles in the accent tint. “Add mapping” opens the shared menu. The rest is in the gear tray, where “Confidence band” shows only while a trend line is on, bins and opacity are number fields, and fixed-set selects show their label only.
facet block: Wrap or Grid and the facet columns on the face, the rest in the gear. Direction is Across or Down.
theme block: base theme, legend and palettes on the face. The gear has colour fields (a swatch and the hex value, opening the browser’s picker) and Auto/Show/Hide segmented controls for grid lines and border.
grid block: the face is the plot; layout, the layout preview and the titles are in the gear.
The layout previews are drawn with the design tokens and follow the dark scheme. The plot image stays light in the dark scheme.

The ggplot, facet and theme blocks now build their expressions as language objects (bquote()/call()/as.call()) instead of assembling and re-parsing strings, and refer to their input as .(data). Generated code names the upstream block directly (plot + ggplot2::theme_bw()) rather than wrapping it in with(list(data = plot), ...), and non-syntactic column names are handled by as.name() rather than manual backticking. This drops the glue dependency.
Text inputs commit on Enter or blur with an “Enter ↵” confirm chip instead of auto-submitting on a 300ms debounce.
The facet and grid blocks no longer show a yellow warning banner when unconfigured: the facet “Facet by” field carries the amber required-empty cue instead, and the layout preview waits until there is something to lay out.
