dm 1.0.0

Features

• New dm_gui() for interactive editing of dm objects (#1076, #1319).

• dm_get_tables() and pull_tbl() gain a new keyed = FALSE argument. If set to TRUE, table objects of class "dm_keyed_tbl" are returned. These objects inherit from the underlying data structure (tibble or lazy table), keep track of primary and foreign keys, and can be used later on in a call to dm() to recreate a dm object with the keys (#1187).

• New by_position argument to check_subset(), check_set_equality(), check_cardinality_...() and examine_cardinality() (#1253).

• dm() accepts dm objects (#1226).

• dm_examine_constraints() honors implicit unique keys defined by foreign keys (#1131, #1209).

Breaking changes

• dm_filter() is now stable, with a new API that avoids exposing an intermediate state with filters not yet applied, with a compatibility wrapper (#424, #426, #1236).

• check_cardinality_...(), examine_cardinality(), check_subset() and check_set_equality() are now stable and consistently use a common interface with arguments named x, y, x_select and y_select, with compatibility wrappers (#1194, #1229).

• dm_examine_cardinalities() and dm_examine_constraints() are now stable with a new signature and a compatibility wrapper (#1193, #1195).

• dm_apply_filters(), dm_apply_filters_to_tbl() and dm_get_filters() are deprecated (#424, #426, #1236).

• dm_disambiguate_cols() adds table names as a suffix by default, and gains a .position argument to restore the original behavior. Arguments sep and quiet are renamed to .sep and .quiet (#1293, #1327).

• dm_squash_to_tbl() is deprecated in favor of the new .recursive argument to dm_flatten_to_tbl(). Arguments start and join are renamed to .start and .join (#1272, #1324).

• dm_rm_tbl() is deprecated in favor of dm_select_tbl() (#1275).

• dm_bind() and dm_add_tbl() are deprecated in favor of dm() (#1226).

• rows_truncate() and dm_rows_truncate() are deprecated, because they use DDL as opposed to all other verbs that use DML (#1031, #1321).

• All internal S3 classes now use the "dm_" prefix (#1285, #1339).

• Add ellipses to all generics (#1298).

API

• Reexport tibble() (#1279).

• dm_ptype(), dm_financial() and dm_pixarfilms() are stable now (#1254).

• Turn all "questioning" functions to "experimental" (#1030, #1237).

Performance

• is_unique_key()uses vctrs::vec_count() on local data frames for speed (@eutwt, #1247).

• check_key() uses vctrs::vec_duplicate_any() on local data frames for speed (@eutwt, #1234).

Bug fixes

• dm_draw() works if a table name has a space (#1219).

• Don't print rule in glimpse.dm() for empty dm() (#1208).

Documentation

• Work around ANSI escape issues in CRAN rendering of vignette (#1156, #1330).

• Fix column names in ?dm_get_all_pks (#1245).

• Improve contrast for display of dm_financial() (#1073, #1250).

• Add contributing guide (#1222).

Internal

• Use sensible node and edge IDs, corresponding to the data model, in SVG graph (#1214).

• Tests for datamodelr code (#1215).
