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:
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:
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. - 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.
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. - Added a new component: Dropdown. A list of selectable labeled entries,
suitable for single and multi-select scenarios.
