Blockly editor

[aslakhellesoy]

🤔 What's changed?

Add a Blockly editor for Gherkin. Preview:

⚡️ What's your motivation?

My motivation is to lower the barrier of entry for people who are either new to Cucumber, or for people with little programming experience. In some cases, a visual editor might also be preferable for seasoned developers who are familiar with Cucumber.

🏷️ What kind of change is this?

• ⚡ New feature (non-breaking change which adds new behaviour)

♻️ Anything particular you want feedback on?

The following needs to be done before this can be merged to main and be included in the next release:

• Make the blockly editor be an alternative view, similar to how a .md document can be viewed in either text mode or rendered mode.
  • Associate the blockly editor with the .feature extension rather than the .gherkin extension, which is just a temporary workaround.
• Make sure edits in the blockly editor saves the .feature file back to the file system.
• Take up the full height and add a scroll bar - if there are many step definitions, they disappear at the bottom of the screen
• Add a disclaimer about unsupported features
  • Tables are not yet supported - see Table block blockly#37
  • Comments will be lots
  • Tags are not (yet) supported

📋 Checklist:

• I agree to respect and uphold the Cucumber Community Code of Conduct
• I've changed the behaviour of the code
  • I have added/updated tests to cover my changes.
• My change requires a change to the documentation.
  • I have updated the documentation accordingly.
• Users should know about my change
  • I have added an entry to the "Unreleased" section of the CHANGELOG, linking to this pull request.

hi @aslakhellesoy

I have followed the build instructions as with all other times I've worked on the extension. However the UI layer will not load if I copy a working .feature to a .gherkin. It claims there is an AssertionError in a modal and this to the output console:

[Error - 7:33:33 PM] Error: Webview is disposed

[Error - 7:33:33 PM] Please report an issue at https://github.com/cucumber/language-service/issues with the above stack trace

Please advise. I believe I can finish the remaining work on this extension.

Hi @mrkaiser I'm not able to reproduce what you describe. This is what I did:

Okay I will try again tonight. It might've been a PEBKAC. Thank you for the response.

Hi @mrkaiser did you have any luck with this?
