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

Download links:

• Windows
• Linux
• macOS (Intel)
• macOS (Apple silicon)

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:

• Windows
• Linux
• macOS (Intel)
• macOS (Apple silicon)

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.
• The IDE now has a new UI element for selecting the execution mode of the project.
• Added tooltips to icon buttons for improved usability. Users can now quickly understand each button's function.
• File associations are created on Windows and macOS. This allows opening Enso files by double-clicking them in the file explorer.
• AI-powered code completions. It is now possible to get AI-powered completions when using node searcher with Tables.
• Added capability to create node widgets with complex UI. Node widgets such as dropdown can now be placed in the node and affect the code text flow.
• The IDE UI element for selecting the execution mode of the project is now sending messages to the backend..
• Feedback when renaming a project. When the user tries to rename the project to an invalid name, a helpful error message is shown and the text field stays the same as to give the user the opportunity to fix the mistake.
• Area selectionof nodes no longer takes into account the visualisation that belongs to the node..
• List Editor Widget. Now you can edit lists by clicking buttons on nodes or by dragging the elements.
• Visualisations now show a loading spinner while waiting on data..
• Fixed text visualisations which were being cut off at the last line.
• Fixed a bug where, when scrolling or dragging on a full-screen visualization, the view of the graph changed as well.
• Changed the shortcut for restoring to the last saved version of a project from <kbd>cmd</kbd>+<kbd>r</kbd> to <kbd>cmd</kbd>+<kbd>shift</kbd>+<kbd>r</kbd> to make it less likely that it would be triggered by accident. As a consequence, the program execution shortcuts changed from <kbd>cmd</kbd>+<kbd>shift</kbd>+<kbd>t</kbd>/<kbd>r</kbd> to <kbd>cmd</kbd>+<kbd>alt</kbd>+<kbd>t</kbd>/<kbd>r</kbd>.
• Fixed a bug where selecting a nested breadcrumb would cause the order of breadcrumbs to change incorrectly.
• Changed the shortcut to show the full-screen visualization for a node from <kbd>space</kbd> <kbd>space</kbd> to <kbd>shift</kbd>+<kbd>space</kbd>. so that it doesn't interfere with the shortcut for toggling the small visualization.
• Cloud dashboard, which supersedes the startup screen. Features also added in various other PRs. The new dashboard includes tables for projects, folders, files and secrets, a list of templates from which new projects can be created, a user menu, and a search bar.
• The Application will try to reload file in backend on synchronization failure. It should make it more resilient to connectivity issues and occasional bugs. The reload may be forced by the user with <kbd>cmd</kbd>+<kbd>shift</kbd>+<kbd>x</kbd> shortcut.
• When selecting a function from the main module through the component browser, it is now referenced via the `Main` namespace instead of the project namespace, e.g. `Main.func1` instead of `MyProject.func1`. This makes it robust against project name changes.
• Added a button to return from an opened project back to the project dashboard.
• Keyboard shortcuts for graph editing are now disabled when the full-screen visualization is active.
• A loading animation is now shown when opening and creating projects, as the previous behaviour of showing a blank screen while the project was being loaded was potentially confusing to users.
• Error message is displayed in the status bar when the backend reports execution failed.
• Performance and readability of documentation panel was improved. The documentation is now split into separate pages, which are much smaller.
• IDE no longer inserts redundant imports when selecting options from dropdown widgets. The code was unified with the component browser, and it now correctly handles reexports and already existing imports.
• Fixed cursor position when ctrl-clicking the node. Sometimes ctrl-clicking to edit the node placed the mouse cursor in the wrong position in the text. This is fixed now.
• Added prototype AI Searcher that can be used to create new nodes from natural language input
• Allow visualization resizing. Now the user can adjust the visualization size by dragging its right and bottom borders. Visualization width also follows the node's width, and visualizations are aligned to the left side of the node.
• Component Browser was redesigned. The three columns of groups turned out to be non-practical, as they give too much information to comprehend. Also, filtering results was kept in groups making second-best match not easily available. Therefore, we introduced a new, impler CB design with single column.
• Help chat. The link to the Discord server is replaced with a chat bridge to the Discord server. This is intended to have the chat visible at the same time as the IDE, so that help can be much more interactive.
• New breadcrumbs design. Breadcrumbs now optionally show the icon of the item they represent. They also follow the new design of the component browser.
• [The libraries' authors may put entities to groups by adding GROUP tag in the docstring]. It was requested as more convenient way than specifying full names in package.yaml.
• Graph editor node was redesigned. Nodes have a color and icon matching the selected entry in the component browser. Clear separating lines between method arguments were added. The node selection was made easier with additional thick interactive selection border.
• The shortcut for opening Component Browser was changed to <kbd>enter</kbd>
• Connections to lamdas are displayed correctly. It is possible to drag a connection to any expression inside the lambda body.
• [Atom types in dropdowns do not produce redundant imports][#7670]. The possibility of imports conflicts is reduced.
• Copying and pasting a single node. Using the common <kbd>cmd</kbd>+<kbd>C</kbd> and <kbd>cmd</kbd>+<kbd>V</kbd> shortcuts, it is now possible to copy a single selected node and paste its code to the graph or another program.

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.
• Performance monitor was extended with the ability to print details of actions performed in a given frame. In particular, you can now inspect names of all symbols rendered in a given frame. You can also pause the performance monitor and inspect results recorded in the past.
• ToggleButtons can now have tooltips.
• Rendering of tooltips was improved. Their text is now more vertically centered and the delay before showing them was extended.
• Accurate GPU performance measurements have been implemented. It is possible now to track both the time spent on both the CPU and the GPU sides.
• Support recovery from GL context loss. This allows the application to continue after an interruption to rendering, such as hibernation or movement of the application window to a display rendered by a different GPU.
