2026-03-18 – Gitignore Template Sources, EOL Configuration, and Templates Schema

Summary

This update adds support for multiple gitignore template sources (DevCentr, GitHub, local), documents line-ending configuration and Windows-specific exceptions, and defines a new templates repository schema with version folders and preference separation.

Gitignore Template Sources

  • DevCentr source: Existing whitelist strategy with ecosystem-specific merges from the templates repo.

  • GitHub source: Added support for github/gitignore as a template source. DevCentr caches the repo under ~/.dev-center/github-gitignore and surfaces root, Global, and community templates.

  • Init Repo dialog: Template source selector (DevCentr vs GitHub) with source-specific template lists. When GitHub is selected, a scrollable list of templates (root, Global, community) appears for selection.

GitHub Base vs Global Structure

Documented in Gitignore Template Sources:

  • Root: Programming languages and core technologies (e.g. VisualStudio, Node, Python).

  • Global: Editors, tools, and operating systems (e.g. VisualStudioCode, Windows). GitHub recommends these for global gitignore or permanent project merges.

  • community: Specialized or version-specific templates.

Line Endings and Windows Exceptions

  • git-management.adoc: Expanded with "Choosing input vs false" guidance and when core.autocrlf input makes sense on Windows.

  • EditorConfig: Added Step 4 with .editorconfig for cross-editor EOL enforcement and CRLF overrides for .bat, .cmd, .reg.

  • windows-eol-exceptions.adoc: New reference documenting when LF breaks on Windows (batch files, registry files, PowerShell, Visual Studio) and EditorConfig overrides.

  • Init Repo: Added .editorconfig tab with default content including Windows exceptions. Initialize flow now writes .editorconfig.

Templates Schema

  • templates-schema.adoc: New specification for the templates repository:

    • Version folders per ecosystem (e.g. d/v1/, node/v18/) for version history.

    • _base/ for preference-agnostic files (no dprint/Prettier specifics).

    • _preferences/ for developer/team overlays (dprint, prettier, org-name).

    • Migration path from current _common/ layout.

Per-Repository Settings

  • gitignore.suppressMissing: Documented in per-repo-settings.adoc for suppressing template-comparison warnings. Stored in .devcentr.sdl.

Gitignore Viewer (Implemented)

  • Reusable MinimapWidget: Miniature document preview with click/drag to scroll. API: setText(), setVisibleRegion(), onScrollRequested().

  • GitignoreViewerWidget: Layout: minimap | plaintext editor | (technology tree + template comparison). Opens in side-panel when user clicks Gitignore View/Edit in hallmark toolbar.

  • Technology tree: Parses .gitignore to recognize Node, Python, D, Rust, Go, Build, Logs, Env, IDE, OS. Clicking a technology highlights related lines in the editor.

  • Template comparison: Tabs for DevCentr, GitHub, Local. Missing template lines shown in red; suppressed (stored in .devcentr.sdl) in gray. "Suppress" button per missing line.

  • Integration: Gitignore compound button added to hallmark when .gitignore exists. Save and Close buttons in viewer toolbar.
