Enso IDE

Enso IDE is the main product of the Enso project. The packages are stand-alone,
they contain both GUI and the backend.

Download links:

• Linux (AppImage);
• macOS (DMG);
• Windows (Installer
  Executable).

This is the recommended download for most users.

Enso Engine

If you are interested in using Enso Engine command line tools only, download the
Enso Engine bundle.

Download links:

• Linux;
• macOS;
• Windows.

These are archives containing the
Enso portable distribution.
User is responsible for setting up the environment variables and adding the
bin directory to the PATH.

Note that these distributions do not allow you to use the Enso IDE.

It is recommended only for advanced users, who want to just try the compiler
CLI.

Anonymous Data Collection

Please note that this release collects anonymous usage data which will be used
to improve Enso and prepare it for a stable release. We will switch to opt-in
data collection in stable version releases. The usage data will not contain your
code (expressions above nodes), however, reported errors may contain brief
snippets of out of context code that specifically leads to the error, like "the
method 'foo' does not exist on Number". The following data will be collected:

• Session length.
• Graph editing events (node creation, deletion, position change, connect,
  disconnect, collapse, edit start, edit end). This will not include any
  information about node expressions used.
• Navigation events (camera movement, scope change).
• Visualization events (visualization open, close, switch). This will not
  include any information about the displayed data nor the rendered
  visualization itself.
• Project management events (project open, close, rename).
• Errors (IDE crashes, WASM panics, Project Manager errors, Language Server
  errors, Compiler errors).
• Performance statistics (minimum, maximum, average GUI refresh rate).

Changelog

Visual Environment

• Camera is panned to newly created nodes.
• 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 <kbd>TAB</kbd> 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 <kbd>TAB</kbd> 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.
• Lazy visualization for scatter plot.
• 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"
• New Version of the Node Searcher - the Component Browser The available
  methods, atoms and functions are presented in nice, categorized view. The most
  popular tools are available at hand. The panel is unstable, and can be
  disabled with the `--enable-new-component-browser=false` flag.
• Fixed error handling during startup. This prevents entering IDE into a
  "zombie" state, where processes were started but not visible to user. They
  could cause issues with starting further IDE instances.
• New nodes are created in the project source when the searcher is opened and a
  new node is created.
• Proper Polyglot Vector and Array Support
• IDE uses new visualization API.
• Visualization of long textual values improved
• Selecting a suggestion from the searcher or component browser now updates the
  visualisation of the edited node to preview the results of applying the
  suggestion.
• Remove here keyword from IDE.
• Shortcut changes: Pressing `Enter` when no node is edited opens
  Component Browser. Entering node shortcut changed to `cmd` + `Enter`.
• Added support for scrolling by pressing and holding a mouse button on a
  scrollbar.
• Added scroll bounce animation which activates when scrolling past the
  end of scrollable content.
• The default text visualisation now loads its content lazily from the
  backend. This means that the visualisation cannot be overwhelmed by
  large amounts of data.
• Added project snapshot saving on shortcut
• The color of the displayed project name indicates whether the project's
  current state is saved in a snapshot. The project name is darker when
  the project is changed from the last saved snapshot and lighter when the
  snapshot matches the current project state.
• Added shortcut to interrupt the program
• Added suggestion dropdown for function arguments. The dropdown is
  present only when the argument is of type that has a predefined set of values.
• Separate component browser navigator sections for modules imported from
  different namespaces
• Internal components (private API) are not displayed in the component
  browser.
• The correct default visualisation for tables is shown on new nodes.
• Added restoring of last project snapshot on shortcut.
• Added contextual suggestions to argument dropdowns. Dropdowns will now
  contain suggestions which are based on evaluated data.
• Added a shortcut to show internal components (private API) in the component
  browser.
• Improved component browser entry filtering and sorting. The component
  browser will now provide suggestions matching either the component's label or
  the corresponding code.
• Improved argument placeholder resolution in more complex expressions.
  It is now possible to drop node connections onto missing arguments of chained
  and nested function calls.
• The component browser suggestions take into account entry aliases. The
  searcher input is now matched to entry aliases too. The alias match is used to
  filter and sort component browser entries.
• The Component Browser icons are cached on texture improving its
  performance on slower machines.
• Fixed missing result preview when editing nodes.
• Application retries its initialization after failures, allowing a
  reconnecting after connectivity problems.
• Improved Component Browser Filtering. The best match is always
  selected first, and the groups are rearranged, so the best matches are on the
  bottom.
• Named arguments syntax is now recognized in IDE. Connections to
  function arguments will now use named argument syntax instead of inserting
  wildcards on all preceding arguments.
• Added boilerplate React app for authorization via Cognito+AWS Amplify.
  This PR adds a React app that renders the dashboard (which has been ported
  from the cloud. The dashboard displays a list of projects, and allows users to
  open them in the IDE (which is not part of the React app, but can be switched
  to from the dashboard). The PR also adds authentication+authorization (i.e.,
  sign up and sign in for users), via either email/password or GitHub/Google.
• New Enso documentation parser. Smaller and faster; enables planned
  improvements to internal documentation representation.
• Dropdown widgets now support custom labels and automatically generate
  shortened labels for entries with long module paths. When an option is
  selected from the dropdown, the necessary module imports are inserted,
  eliminating the need for fully qualified names.

EnsoGL (rendering engine)

• You can change font and set letters bold in the <code>text::Area</code>
  component. Use the <code>set_font</code> and
  <code>set_bold_bytes</code> respectively.
• Fixed a text rendering issue in nested sublayer.
• Added a new component: Grid View. It's parametrized by Entry object,
  display them arranged in a Grid. It does not instantiate all entries, only
  those visible, and re-use created entries during scrolling thus achieving
  great performance. There are variants of grid view with selection and
  highlight, scrollbars, and both.
• Massive improvements of text rendering performance. Different text
  instances are now reusing the shape shaders and the same sprite system under
  the hood. This drastically reduces the amount of required draw calls for
  scenes with a lot of text.
• Text rendering quality improvements. Glyphs are now hinted in a better
  way. Also, additional fine-tuning is performed per font and per host operating
  system.
• Display objects can now emit and receive events in the same style as
  JavaScript DOM events. The events system implements very similar
  behavior to the one described here:
  https://javascript.info/bubbling-and-capturing.
• Added a new component: Slider. It allows adjusting a numeric value
  with the mouse. The precision of these adjustments can be increased or
  decreased.
• Slider component functionality improvements. The slider component now
  supports multiple ways to handle out-of-range values. The slider's value can
  be edited as text, and a new vertical slider layout is available.
• Added ProjectsGrid view for Cloud Dashboard. It provides the first
  steps towards migrating the Cloud Dashboard from the existing React (web-only)
  implementation towards a shared structure that can be used in both the Desktop
  and Web versions of the IDE.
• Removed Cloud Dashboard. The Cloud Dashboard was being rewritten in
  EnsoGL but after internal discussion we've decided to rewrite it in React,
  with a shared implementation between the Desktop and Web versions of the IDE.
• Added a new component: Dropdown. A list of selectable labeled entries,
  suitable for single and multi-select scenarios.
• Compile-time shader optimizer was implemented. It is capable of
  extracting non-optimized shaders from the compiled WASM artifacts, running
  stand-alone optimization toolchain (glslc, spirv-opt, spirv-cross), and
  injecting optimized shaders back to WASM during its initialization process.
  Unfortunately, it caused our theme system to stop working correctly, because
  generated shaders differ per theme (only light theme is available, the dark
  theme has been disabled). We will support multiple themes in the future, but
  this is not on our priority list right now.
