Enso 2022.1.1-nightly.2022-03-31

Visual Environment

• Nodes can be added to the graph by double-clicking the output ports of
  existing nodes (or by clicking them with the right mouse button).
• Node Searcher preserves its zoom factor. The visible size of the node
  searcher and edited node is now fixed. It simplifies node editing on
  non-standard zoom levels.
• Nodes can be added to the graph by clicking (+) button on the screen.
  The button is in the bottom-left corner. Node is added at the center or pushed
  down if the center is already occupied by nodes.
• Maximum zoom factor is limited to 1.0x if IDE is not in Debug Mode.
• Debug Mode for Graph Editor can be activated/deactivated using a
  shortcut. It allows access to a set of restricted features. See
  debug-shortcuts.
• New nodes can be created by dragging and dropping a connection on the
  scene.
• Node connections can be dropped by pressing the Esc key while dragging
  them.
• Added support of source maps for JS-based visualizations.
• Fixed histograms coloring and added a color legend.
• Fixed broken node whose expression contains non-ASCII characters.
• Fixed developer console warnings about views being created but not
  registered.
• Fixed developer console errors related to Language Server (mentioning code
  3003 and "Invalid version"), occurring during project opening and after new
  node cration.
• Fixed developer console error about failing to decode a notification
  "executionContext/visualisationEvaluationFailed"

Enso Standard Library

  Vector

• Implemented the Table.remove_columns and Table.reorder_columns
  operations.
• Implemented the Table.sort_columns operation.
• Fixed Vector.sort to handle tail-recursive comparators
• Implemented Range.find, Table.rename_columns and
  Table.use_first_row_as_names operations
• Implemented Text.at and Text.is_digit methods
• Implemented Runtime.get_stack_trace together with some utilities to process
  stack traces and code locations
• Implemented Vector.flatten
• Significant performance improvement in Natural_Order and new Faker
  methods added to Standard.Test
• Implemented Integer.parse
• Made Text.compare_to correctly handle Unicode normalization
• Extend Text.contains API to support regex and case insensitive
  search.
• Implemented new Text.take and Text.drop functions, replacing existing
  functions
• Implemented new Text.starts_with and Text.ends_with functions, replacing
  existing functions
• Implemented Text.to_case, replacing Text.to_lower_case and
  Text.to_upper_case
• Implemented initial Table.group_by function on Standard.Table
• Implemented Text.pad and Text.trim
• Updated Text.repeat and added * operator shorthand
• General improved Vector performance and new Vector.each_with_index,
  Vector.fold_with_index and Vector.take methods.
• Implemented new Text.insert method

• Implemented Map.first, Map.last functions. Expanded Table.group_by to
  also compute mode, percentile, minimum, maximum.
• Implemented Text.location_of and Text.location_of_all methods.
• Replaced Table.group_by with Table.aggregate
