wk 0.9.1

• Fix format strings/arguments for R-devel (#209).

wk 0.9.0

Breaking changes

• The common well-known binary representation of POINT EMPTY (i.e., POINT (nan nan)) is now handled as POINT EMPTY allowing empty points to roundtrip through wkb() vectors (#196, #204).
• xy(NA, NA) is now read as a null feature instead of POINT EMPTY. This preserves the invariant that null features can also be identified using is.na() (#205).
• xy(NaN, NaN) is now read as POINT EMPTY and is.na(xy(NaN, NaN)) now returns FALSE. This means that both EMPTY and null points can roundtrip through xy() (#205).

Bugfixes and improvements

• wk_meta() now contains a new column is_empty, which is TRUE for any feature that contains at least one non-empty coordinate. This allows more efficient detection of features with zero coordinates (#197, #199).
• Updated PROJ data to use the latest pull of the database packaged with PROJ 9.3.0 (#201).
• The wk package now compiles once again on gcc 4.8 (#203, #206).
• Fixed sfc_writer() to correctly attach the classes attribute to sfc output with mixed geometry types (#195).
• Function sfc_writer() now has an argument promote_multi to write any input as the MULTI variant. This makes it more likely that an input vector will be read as a single geometry type (#198).
• The wk_collection_filter() now correctly increments the part_id when calling the child handler (@brownag, #194).

wk 0.8.0

• Added wkb_to_hex() (@anthonynorth, #183).
• Implemented vctrs::vec_proxy_equal() for wkb() vctrs (@anthonynorth, #183).
• Fixed sfc_writer(), which had returned NULL for some inputs (e.g., via wk_collection()) (@anthonynorth, #182, #186).
• Added wk_clockwise() and wk_counterclockwise() to re-wind polygon rings (@anthonynorth, #188).
• New replacement-function mode for wk_coords<-() for in-place modification of coordinates (@mdsumner, #187).
• New function wk_trans_explicit() migrated from crs2crs (@mdsumner, #187).

wk 0.7.3

• Fix tests for updated waldo package (#178).

wk 0.7.2

• Fix use-after-free warnings.

wk 0.7.1

• Fix implicit reliance on error as.data.frame.default(), which no longer occurs in r-devel (#166).

wk 0.7.0

• Remove legacy headers that are no longer used by any downstream package (#146).
• validate_wk_wkt() now errors for an object that does not inherit from ‘wk_wkt’ (#123, #146).
• Added wk_crs_projjson() to get a JSON representation of a CRS object. To make lookup possible based on shortcut-style CRS objects (e.g., "EPSG:4326" or 4326), added data objects wk_proj_crs_view and wk_proj_crs_json that contain cached versions of rendered PROJJSON based on the latest PROJ version (#147).
• Added a wk_crs_proj_definition() method for wk_crs_inherit() (#136, #147).
• Conversion to sf now uses the sfc_writer() for all wk classes, making conversions faster and fixing at least one issue with conversion of NA geometries to sf (#135).
• wk_plot() now plots NULL/NA geometries and mixed geometry types more reliably (#142, #143, #149).
• Exported EMPTY geometries to well-known text now include dimension (e.g., POINT Z EMPTY) (#141, #150).
• Fixed bug where wk_polygon() doubled some points when the input contained closed rings (#134, #151).
• Fixed bug where wk_count() exposed uninitialized values for empty input (#139, #153).
• The xy_writer() now opportunistically avoids allocating vectors for Z or M values unless they are actually needed (#131, #154).
• Added example WKT for all geometry types and dimensions plus helper wk_example() to access them and set various properties (#155).
• Fixes warnings when compiling with -Wstrict-prototypes (#157, #158).
• Removed wk_chunk_map_feature() in favour of using chunking strategies directly (#132, #159).
• Optimized wk_coords() for xy() objects (#138, #160).
• Added accessor methods for record-style vectors: rct_xmin(), rct_xmax(), rct_ymin(), rct_ymax(), rct_width(), rct_height(), crc_center(), crc_x(), crc_y(), crc_r(), xy_x(), xy_y(), xy_z(), and xy_m() (#144, #161).
• Added rectangle operators rct_intersects(), rct_contains(), and rct_intersection() (#161).

wk 0.6.0

• Fixed wk_affine_rescale() to apply the translate and scale operations in the correct order (#94).
• Add wk_handle_slice() and wk_chunk_map_feature() to support a chunk + apply workflow when working with large vectors (#101, #107).
• C and R code was rewritten to avoid materializing ALTREP vectors (#103, #109).
• Added a wk_crs_proj_definition() generic for foreign CRS objects (#110, #112).
• Added wk_crs_longlat() helper to help promote authority-compliant CRS choices (#112).
• Added wk_is_geodesic(), wk_set_geodesic(), and argument geodesic in wkt() and wkb() as a flag for objects whose edges must be interpolated along a spherical/ellipsoidal trajectory (#112).
• Added sf::st_geometry() and sf::st_sfc() methods for wk geometry vectors for better integration with sf (#113, #114).
• Refactored well-known text parser to be more reusable and faster (#115, #104).
• Minor performance enhancement for is.na() and validate_wk_wkb() when called on a very long wkb() vector (#117).
• Fixed issue with validate_wk_wkb() and validate_wk_wkt(), which failed for most valid objects (#119).
• Added wk_envelope() and wk_envelope_handler() to compute feature-wise bounding boxes (#120, #122).
• Fixed headers and tests to pass on big endian systems (#105, #122).
• Incorporated the geodesic attribute into vctrs methods, data frame columns, and bbox/envelope calculation (#124, #125).
• Fix as_xy() for nested data frames and geodesic objects (#126, #128).
• Remove deprecated wkb_problems(), wkt_problems(), wkb_format(), and wkt_format() (#129).
• wk_plot() is now an S3 generic (#130).

wk 0.5.0

• Fixed bugs relating to the behaviour of wk classes as vectors (#64, #65, #67, #70).
• crc() objects are now correctly exported as polygons with a closed loop (#66, #70).
• Added wk_vertices() and wk_coords() to extract individual coordinate values from geometries with optional identifying information. For advanced users, the wk_vertex_filter() can be used as part of a pipeline to export coordinates as point geometries to another handler (#69, #71).
• Added wk_flatten() to extract geometries from collections. For advanced users, the wk_flatten_filter() can be used as part of a pipeline (#75, #78).
• options("max.print") is now respected by all vector classes (#72, #74).
• Moved implementation of plot methods from wkutils to wk to simplify the dependency structure of both packages (#80, #76).
• Added wk_polygon(), wk_linestring(), and wk_collection() to construct polygons, lines, and collections. For advanced users, wk_polygon_filter(), wk_linestring_filter(), and wk_collection_filter() can be used as part of a pipeline (#77, #84).
• Added a C-level transform struct that can be used to simplify the the common pattern of transforming coordinates. These structs can be created by other packages; however, the wk_trans_affine() and wk_trans_set() transforms are also built using this feature. These are run using the new wk_transform() function and power the new wk_set_z(), wk_set_m(), wk_drop_z(), wk_drop_m(), functions (#87, #88, #89).

wk 0.4.1

• Fix LTO and MacOS 3.6.2 check errors (#61).

• Removed wksxp() in favour of improved sf::st_sfc() support (#21).
• Rewrite existing readers, writers, and handlers, using a new C API (#13).
• Use new C API in favour of header-only approach for all wk functions (#19, #22).
• Use cpp11 to manage safe use of callables that may longjmp from C++.
• Vector classes now propagate attr(, "crs"), and check that operations that involve more than one vector have compatable CRS objects as determined by wk_crs_equal().
• Added an R-level framework for other packages to implement wk readers and handlers: wk_handle(), wk_translate(), and wk_writer() (#37).
• Added a native reader and writer for sf::st_sfc() objects and implemented R-level generics for sfc, sfg, sf, and bbox objects (#28, #29, #38, #45).
• Implement crc() vector class to represent circles (#40).
• Added a 2D cartesian bounding box handler (wk_bbox()) (#42).
