📝 Walkthrough

Walkthrough

The administration guide documents workspace.openProjectsRootOnEmpty in the vscode-editor-configurations ConfigMap. When no projects or workspace folders are configured, setting it to true opens /projects.

Changes

Empty Workspace Projects Root

Layer / File(s) Summary
Document the empty-workspace setting
modules/administration-guide/pages/configuring-single-and-multiroot-workspaces.adoc
Documents how to set workspace.openProjectsRootOnEmpty to true. States that it applies when there are no projects, dependent projects, starter projects, or configured workspace folders.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~4 minutes

Change: Other

Merge Risk: 🔵 Low · up to 1c688

The guide’s ConfigMap example cannot be applied unchanged because its YAML placeholder fails parsing. Removing that line is a small fix; the documented setting and scope otherwise match the linked launcher behavior.

Architecture Summary

Architecture risk: 🔵 Low · up to 1c688

The change affects 1 system.

Based on the standup discussion it was decided to make this property part of the existing vscode-editor-configurations CM - https://eclipse.dev/che/docs/stable/administration-guide/editor-configurations-for-microsoft-visual-studio-code/

I propose making it part of settings.json only and not export on the devfile / env var level

CQA 2.1 + JTBD review. Content direction (ConfigMap-based workspace.openProjectsRootOnEmpty) looks right and matches the current diff on che-incubator/che-code#814, but a few things should be addressed before merge:

  • che-incubator/che-code#814 (the implementing PR) is still open, not merged. Recommend holding this docs PR until that lands, since the mechanism changed shape twice already during review (env var → devfile field → ConfigMap setting).
  • The PR checklist boxes ("Successfully tested", "Builds on Eclipse Che hosted by Red Hat", "Vale warnings") are all unchecked. Please confirm these before merge.
