Enso 2022.1.1-nightly.2022-05-31

Visual Environment

• Long names on the Node Searcher's list are truncated. The part of the
  name that doesn't fit in the Searcher's window is replaced with an ellipsis
  character ("…").
• Magnet Alignment algorithm is used while placing new nodes. When we
  find an available free space for a new node, the node gets aligned with the
  surrounding nodes horizontally and vertically. This helps to preserve a nice
  grid-like layout for all the nodes.
• Nodes created via the TAB key or by clicking the (+) button on the
  screen are now placed below all the selected nodes when more than one node is
  selected. (Previously, they were placed below the first node that was
  selected.) This makes it easier to achieve a compact, vertical layout of the
  graph.
• Nodes created near existing nodes via the TAB key or by dropping a
  connection are now repositioned and aligned to existing nodes. This is
  to make the resulting graph prettier and avoid overlapping. In such cases,
  created nodes will be placed below an existing node or on the bottom-left
  diagonal if there is no space underneath.
• 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 the alignment of newly created nodes to existing nodes with
  visualizations enabled. When applicable, new nodes are now placed below
  visualizations. (Previously, they were placed to the left of the
  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"

EnsoGL (rendering engine)

• You can change font and set letters bold in the text::Area
  component. Use the set_font and
  set_bold_bytes respectively.
• Fixed a text rendering issue in nested sublayer.

Enso Standard Library

  Vector

  expression within the UI

  Vector.filter_with_index. Made Vector.at accept negative indices and
  ensured it fails with a dataflow error on out of bounds access instead of an
  internal Java exception.

• Implemented the Table.remove_columns and Table.reorder_columns
  operations.
• Implemented the Table.sort_columns operation.
• Fixed Vector.sort to handle tail-recursive comparators

  Table.use_first_row_as_names operations

• 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 Bool.compare_to 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
• Implemented Panic.catch and helper functions for handling errors. Added a
  type parameter to Panic.recover to recover specific types of errors.
• Added warning handling to Table.aggregate
• Improved performance of Table.aggregate and full warnings
  implementation
• Implemented Text.reverse
• Implemented support for most Table aggregations in the Database
  backend.
• Update Text.replace to new API.
• Add encoding support to Text.bytes and Text.from_bytes. Renamed and added
  encoding to File.read_text. New File.read API.
• Improved the Range type. Added a down_to counterpart to up_to and
  with_step allowing to change the range step.
• Aligned Text.split API with other methods and added Text.lines.
• Implemented a basic reader for the Delimited file format.
• Implemented a reader for the Excel file format.
• Added custom encoding support to the Delimited file format reader.
• Implemented compute method on Vector for statistics calculations.
• Promote get and put to be methods of Ref type rather than of Ref
  module
• Implemented Table.parse_values, parsing text columns according to a
  specified type.
• Promote with, take, finalize to be methods of Managed_Resource
  instance
• Implemented automatic type detection for Table.parse_values.
• Integrated value parsing with the Delimited file reader.
• Implemented the Infer setting for headers in the Delimited file format
  and made it the default.
• Implemented a Table.from Text conversion allowing to parse strings
  representing Delimited files without storing them on the filesystem.
• Added rank data, correlation and covariance statistics for Vector

  signatures
• Generate boilerplate classes related to error handling and varargs in
  builtins from method signatures
