Changelog • r2slides

Version 0.0.9076

You can now read most elements of existing slides back into R: pull the elements off a slide and get their text, formatting, position, images, and linked spreadsheets. This allows prototypes - use the styling of another already existing element. Or fuzzy positioning - use the position of an already existing element.

New register_spreadsheet(id) and new_spreadsheet(title) functions create a lean R6 spreadsheet class that mirrors the presentation workflow. The active spreadsheet is stored in the package environment and retrieved with get_active_spreadsheet(), so write_gs() no longer requires a global ss object.
write_gs() now accepts an r2slides::spreadsheet object, a googlesheets4::sheets_id, or any object accepted by googlesheets4::as_sheets_id() via its new spreadsheet argument (default: get_active_spreadsheet()).
sht_id and chart_id are now S7 classes with property access via @. The old new_sht_id() and new_chart_id() S3 constructors are removed — use sht_id() and chart_id() directly. is_sht_id() now uses S7 inheritance so it returns TRUE for chart_id objects.
create_spreadsheet_env_in_global() and the google_spreadsheet global environment pattern are removed.

solid_color() now stores red/green/blue as numeric components (no hex round-trip) and accepts all the same inputs as before. theme_color() is a new exported class for Google Slides theme color references (e.g. "ACCENT1"). Both extend a common r2s_color base class that carries an optional alpha channel. The old transparent_color() class is removed — pass alpha directly to solid_color() or theme_color() instead. A new visualize() generic renders a color swatch or theme name. Colors with alpha set used in text-style contexts now produce a warning that alpha will be ignored.

New lazy evaluation strategy: use set_evaluation_strategy("lazy") to buffer API requests instead of executing them immediately, then flush with execute_requests(). get_evaluation_strategy() returns the current setting. view_request_buffer() inspects queued requests and clear_request_buffer() resets the buffer. execute_requests(batch_all = TRUE) (the default) merges all pending batchUpdate requests for the same presentation into a single API call.

Text style objects can style and text with several different styles
Style rule objects apply text style objects to text which matches a selector function

Built in default OAuth client now means that this package will work from anyone’s computer (Once their google account has been whitelisted)

Initial Commit
Basically just put my local functions in a package. It will not build yet. (Namespace stuff mainly)
CI Workflow setup - test, coverage, and documentation website automatically runs
