Worked on #7784

Worked with AST to make proper input interpretation. Added several helper functions. Not working yet, but I'm close.

[Frizi]

• fixed some edge cases in text edit translation logic [GUI2] LS file update is broken when adding a newline. #7967
• improved reliability of engine connection and state transitions, added retries on timeouts and improved logging Make engine connections more robust against occasional timeouts #7995
• Added dimming to nodes during evaluation and loaders to visualizations

• Improved visuals of code editor, added resizing

• Currently working on using real Enso AST within the graph view. Reading graph definition from AST #7791

I finally finished all tasks presented in recent weeks:

• Make the code editor editable again #7844
• Add automatic generation of missing group colors #7902
• Create and edit nodes in temporary ast nodes with execution context disabled #7779

Currently working on documentation panel for the new IDE (#7924),

And here is the big demo of the entire GUI promised last week:

Important notice: to have it so flawlessly working, you must remove old metadata (even from freshly created project) leaving at least 3 newlines at the end.

• The build script support for new GUI/IDE landed (New GUI/IDE build script support #7832) — CI checks the new GUI project and the new IDE is uploaded as a CI run artifact:
  
• Spent quite much time on CI issues.
  • The issue with AppImage should be now resolved. (Thanks to Dmitrii!).
• Working on a follow-up build script update that will upload new IDE builds to the release assets.

We have finally a huge progress with website. What has been done:

• The top navigation floating panel is now functioning, allowing to scroll the website by clicking.
• Website has anchors, so you can send a link to people to a particular section, like enso.org/#virtual-data-depot.
• There is a buy button now which redirects to empty website, but we are working on putting pricing there right now.
• We have really nice nodes and visualization animations. They are crucial to show the users how the product works. For example, if user selects "parse", they should see how things are being parsed. If you are used to the concept, it's obvious, but when you see the product/animation for the first time, you need a guidance to understand it and time to digest it.
• The animation framework to create nodes is really nice now - here is a part of the animation definition:

        transformNode(
          () => WORKBENCH.node1.current,
          stage1_node1,
          stage2_node1
        ),

        createNode(() => WORKBENCH.node2.current, {
          vizData: fileData.shopLocations(),
          afterTypingEnd: [
            {
              fn: (t) => {
                WORKBENCH.node2.current.modifyVizData((data) => {
                  const opacity = 1 - t * 0.5;
                  data.meta.columnOpacity = [
                    opacity,
                    opacity,
                    opacity,
                    opacity,
                  ];
                });
              },
            },
          ],
        }),

        selectOptions(
          () => WORKBENCH.node2.current,
          [1],
          [
            {
              add: '"Latitude"',
              fn: (t) => {
                WORKBENCH.node2.current.modifyVizData((data) => {
                  const opacity = 0.5 + t * 0.5;
                  data.meta.columnOpacity[2] = opacity;
                });
              },
            },
            {
              add: '"Longitude"',
              fn: (t) => {
                WORKBENCH.node2.current.modifyVizData((data) => {
                  const opacity = 0.5 + t * 0.5;
                  data.meta.columnOpacity[3] = opacity;
                });
              },
            },
          ]
        ),

Things to be done below. Based on the velocity last week, I'm very positive to have it this week:

• Rest of node animations (4 missing sections).
• Pricing page.
• Linking to example videos.
• Connecting chat.
• Fixing bugs on mobile.

I've been finishing #7884--the last part remaining is finishing resolution of a longstanding TODO to produce complete span info in the parser (#5449). At this point there are a few known unhandled cases, but most nodes should be working and I don't think any other changes will be needed on the TS side, so the PR should be ready to start integration; I will complete #5449 and write more comprehensive tests in a follow-up PR.
