Changes in version 0.4.0 (2026-04-14)                  

New features

Per-worksheet intelligence

  - twb_sheet_shelves() — extract every field placed on rows, cols, or
    an encoding shelf (color, size, label, detail, tooltip) for one or
    all worksheets.
  - twb_sheet_filters() — extract worksheet-level filters including
    categorical member lists, range min/max, and include/exclude mode.
  - twb_sheet_axes() — extract per-axis configuration: reversed,
    include-zero, and scale type (linear, log, …).
  - twb_sheet_sorts() — extract sort directives with sort direction and
    method (field aggregate, alphabetic, manual, data-source order).
  - All four are exposed on TwbParser as get_sheet_shelves(),
    get_sheet_filters(), get_sheet_axes(), get_sheet_sorts() and as
    no-parens active bindings (parser$sheet_shelves, etc.).

Per-dashboard intelligence

  - twb_dashboard_sheets() — list every worksheet placed on a dashboard
    with zone id and pixel position (x, y, w, h).
  - twb_dashboard_layout() — full zone tree including parent zone id,
    component type (worksheet / filter / container / …), layout type
    (tiled / floating), and pixel bounds.
  - twb_dashboard_actions() — extract filter and URL actions with source
    and target sheets, run-on trigger type, and URL value.
  - All three are exposed on TwbParser as get_dashboard_sheets(),
    get_dashboard_layout(), get_dashboard_actions() and as active
    bindings.

Bug fixes

  - plot_relationship_graph(): fixed edge direction — the from vertex
    was incorrectly built from right_field instead of left_field.
  - plot_source_join_graph(): fixed reference to non-existent columns
    left_source / right_source; replaced with left_table / right_table.
  - infer_implicit_relationships(): added deduplication before the
    field-name self-join to prevent Cartesian explosion when many tables
    share a field name; added relationship = "many-to-many" to suppress
    the dplyr 1.1+ warning.
  - Fixed integer_ typo in insights.R that caused errors when parsing
    dashboard zone dimensions.

Internal

  - Canonical .twb_clean_table() and .twb_clean_field() helpers added to
    utils.R, replacing four independent copies scattered across
    fields.R, calculated_fields.R, relationships.R, joins.R, and
    dependency_graph.R.
  - .twb_clean_field() now correctly strips Tableau column-instance
    prefixes (none:Category:nk → Category) and returns unnamed vectors.

                 Changes in version 0.3.1 (2025-12-10)                  

  - Remove use of unlockBinding() in internal TwbParser active-binding
    helpers. This avoids CRAN's "possibly unsafe call" NOTE while
    keeping the same user-facing behaviour for no-parens properties
    (overview, pages, datasources, etc.).

                        Changes in version 0.3.0                        

  - Added a NEWS.md file to track changes to the package.
