Implement plugin system with analytics, social icons, and scholar plugins by compscidr · Pull Request #520 · goblogplatform/goblog

compscidr · 2026-03-17T02:54:15Z

Summary

Adds a hybrid plugin system supporting compiled-in Go plugins and dynamically loaded plugins via the Yaegi interpreter. Includes three production plugins that replace previously hardcoded features.

Plugin Architecture

Interface — plugins implement only what they need via BasePlugin embedding:

Settings() — plugin-specific config shown in admin UI, stored in dedicated plugin_settings table
ScheduledJobs() — periodic background tasks
TemplateHead() / TemplateFooter() — inject HTML into pages
TemplateData() — inject data accessible in templates as {{ .plugins.name.key }}
Pages() — register dynamic page types
RenderPage() — handle rendering plugin-owned pages

Two loading modes:

Compiled-in: Import and register in main()
Dynamic: Drop .go files into plugins/dynamic/, loaded at startup via Yaegi — no recompilation needed

Admin Settings UI:

Plugin settings separated from core settings in their own cards
Each plugin has a collapsible card with enable/disable toggle
Cards start collapsed, clickable header to expand
Per-plugin save buttons

Included Plugins

Google Analytics (plugins/analytics/)

Configurable measurement ID and enable toggle
Injects GA script into <head> when enabled

Social Icons (plugins/socialicons/)

10 social platform URLs (GitHub, LinkedIn, X, etc.)
Renders icon links in footer via TemplateFooter
Migration moves existing social URL settings from core settings table to plugin_settings
Enabled by default for existing installs

Google Scholar (plugins/scholar/)

Registers a "research" dynamic page type
Auto-creates the page record in DB on init (user customizes title, slug, hero via admin)
Migrates ScholarID from legacy page field to plugin settings
Daily background cache refresh via scheduled job
Configurable: scholar ID, article limit, cache file paths
When disabled: page disappears from nav, shows 404 to visitors

Integration Changes

Blog.Render() helper wraps c.HTML() with plugin data injection (all 32 calls migrated)
plugin_head_html / plugin_footer_html injection points in all theme headers/footers
PageFilter on Blog filters nav pages — hides pages owned by disabled plugins
DynamicPage default case delegates to plugin registry, shows 404 for disabled plugin pages
Admin pages list shows "plugin disabled" badge and yellow highlight
Admin page editor shows warning banner with link to enable the plugin
Scholar-specific fields removed from page editor (now in plugin settings)
Scholar removed from Blog struct — no longer a core dependency
Migrations clean up plugin-namespaced keys from main settings table

File Structure

plugin/
  plugin.go         — Plugin interface, BasePlugin, types
  registry.go       — Registry, middleware, template injection, page routing
  registry_test.go  — Tests for registration, seeding, data injection
  setting.go        — PluginSetting model (separate table)
  loader.go         — Yaegi dynamic plugin loader
  symbols.go        — Type exports for Yaegi interpreter
plugins/
  analytics/        — Google Analytics plugin
  socialicons/      — Social media icon links plugin
  scholar/          — Google Scholar integration plugin

Closes #480

Test plan

All existing tests pass
Plugin registry tests: registration, setting seeding, template data injection, GetAllSettings
Scholar sort test migrated to plugin package
Enable/disable analytics plugin — GA script appears/disappears from page source
Enable/disable social icons — footer icons appear/disappear
Enable/disable scholar — research page appears/disappears from nav, shows 404 when disabled
Admin pages list shows "plugin disabled" badge for research when scholar disabled
Admin page editor shows warning banner for disabled plugin pages
Plugin settings save correctly via per-plugin save buttons

🤖 Generated with Claude Code

Adds a plugin architecture that allows extending goblog without forking. Plugins can inject HTML into templates, provide data to templates, register scheduled background jobs, and define their own settings in the admin UI. Plugin interface (plugin/plugin.go): - Name, DisplayName, Version for identity - Settings() for plugin-specific configuration - ScheduledJobs() for periodic background tasks - TemplateHead/TemplateFooter for HTML injection - TemplateData for template data enrichment - BasePlugin provides no-op defaults Registry (plugin/registry.go): - Register compiled-in plugins - Init seeds plugin settings, calls OnInit - StartScheduledJobs launches background goroutines - InjectTemplateData enriches template data before render - GetAllSettings for admin UI - Gin middleware stores registry on context Dynamic loading (plugin/loader.go): - Yaegi Go interpreter loads .go files from plugins/dynamic/ - Dynamic plugins implement the same Plugin interface - No recompilation needed for dynamic plugins Integration: - Blog.Render() helper wraps c.HTML with plugin data injection - All 32 c.HTML calls in blog.go replaced with b.Render - Plugin middleware added to router in goblog.go - Template injection points in all theme headers/footers - Plugin settings section on admin settings page Proof of concept: Google Analytics plugin (plugins/analytics/) - Configurable measurement ID and enable/disable toggle - Injects GA script into <head> when enabled Closes #480 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

blog/blog.go:1026

b.Render is being called with a non-template string ("Error loading .env file: ...") as templateName. Gin will treat this as a template filename and fail to render, breaking the login page when both .env and local.env are missing/unreadable. Use an actual template (e.g. error.html) and pass the error message via the data map (e.g. description/error).

			b.Render(c, http.StatusInternalServerError, "Error loading .env file: "+err.Error(), gin.H{
				"logged_in":  b.auth.IsLoggedIn(c),

Theme switching: - Reload page after theme change so new templates take effect immediately instead of showing stale "Settings updated" message Admin settings layout: - Separate site settings into a "General" card - Each plugin gets its own card with header showing display name - Plugin save buttons are per-plugin, not one global button - updatePluginSettings now scopes to the closest form Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

- Plugin cards are collapsed by default, expanded only when enabled - Enabled setting rendered as a Bootstrap switch checkbox in the card header instead of a text input - Toggling the checkbox immediately saves the enabled state and expands/collapses the settings card - The "enabled" field is excluded from the settings form body since it lives in the card header - Save button includes the enabled state along with other settings Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

- Card header is clickable to expand/collapse regardless of enabled state - Cards start collapsed by default so the page is clean - Enable/disable toggle only saves the setting, doesn't control collapse - stopPropagation on the switch prevents clicking it from also toggling the collapse Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Plugin settings were stored in the main settings table with namespaced keys (analytics.enabled, analytics.tracking_id), which caused them to appear in the global settings form. - Add PluginSetting model with composite PK (plugin_name, key) - Auto-migrate plugin_settings table in Registry.Init() - Add UpdateSetting method on Registry - Add PATCH /api/v1/plugin-settings endpoint for saving plugin settings - Update JS to use the new endpoint for both toggle and form save - Remove blog.Setting dependency from plugin package Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Remove any dot-namespaced keys (e.g. analytics.enabled) from the settings table that were seeded before plugin settings moved to their own plugin_settings table. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Move social URL settings out of the core settings table and hardcoded footer templates into a socialicons plugin. Plugin (plugins/socialicons/): - Defines settings for 10 social platforms (GitHub, LinkedIn, X, etc.) - TemplateFooter renders icon links with Font Awesome - TemplateData provides structured links list for themes that want it - Enabled by default Migration: - Moves existing social URL values from settings to plugin_settings - Removes the social URL keys from the main settings table - Sets socialicons.enabled to true for existing installs Footer templates: - Removed hardcoded social icon blocks from all three themes - Social icons now rendered via {{ .plugin_footer_html }} Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Move the scholar integration out of the Blog struct and into a standalone plugin. The plugin defines a "research" dynamic page type that renders when enabled, and disappears from the site when disabled. Plugin interface additions: - Pages() — plugins can register dynamic page types - RenderPage() — plugins handle rendering their own pages - Registry.GetPagePlugin/RenderPluginPage/GetNavItems for page routing - Registry.IsPluginEnabled for checking enabled state Scholar plugin (plugins/scholar/): - Owns the scholar.Scholar instance internally - Configurable: scholar_id, article_limit, cache file paths - Scheduled job: daily cache refresh in background - Renders page_research.html with articles data Blog changes: - Removed scholar field from Blog struct - Removed Blog.New scholar parameter - Removed Research handler and sortArticlesByDateDesc - DynamicPage default case now delegates to plugin registry - Moved sort test to plugin package Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

- OnInit ensures a research page exists in the pages table with default title, slug, nav settings. Users can customize these via the admin page editor. - Migrates ScholarID from legacy page field to plugin settings for backward compatibility with existing installs. - When the scholar plugin is disabled, visiting the research page shows a "Page Not Available" 404 instead of an empty content page. - Added HasPageType to registry to distinguish "plugin disabled" from "no plugin for this page type". Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

- Remove PageTypeResearch constant (now plugin-defined) - Mark ScholarID on Page as deprecated (kept for migration compat) - Add PageFilter to Blog struct, applied in GetNavPages to filter out pages owned by disabled plugins - Add IsPageTypeEnabled to registry for checking if the plugin that owns a page type is enabled - Wire up the filter in goblog.go after registry init - Update seed defaults and tests to use string literal "research" When the scholar plugin is disabled: - Research page disappears from navigation - Visiting /research shows "Page Not Available" 404 When re-enabled, everything comes back automatically. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Admin pages list (/admin/pages): - Rows for pages with disabled plugins highlighted in yellow - "plugin disabled" badge shown next to the page type - Enabled column shows "Plugin disabled" instead of Yes/No Admin page editor (/admin/pages/:id): - Warning banner at top when the page's plugin is disabled, with link to Settings to enable it - Removed scholar-specific Google Scholar ID field (now in plugin settings) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Pull request overview

This PR introduces a first-class plugin system for goblog (compiled-in and dynamically loaded via Yaegi), integrates plugin-provided data/HTML into template rendering, and adds admin UI + migrations to support plugin settings and plugin-owned pages.

Changes:

Add plugin framework (registry, settings table, middleware, Yaegi dynamic loader) plus initial plugins (Analytics, Social Icons, Scholar).
Route all template rendering through Blog.Render() so plugins can inject template data and head/footer HTML.
Update admin UI + migrations: plugin settings management endpoint/UI, social URL settings migrated into plugin_settings, and admin page warnings when plugin-owned page types are disabled.

Login() passes an error message string as the template name to Render, which will make Gin try to render a template named like "Error loading .env file: ...". This should render a real template (e.g. error.html) and pass the error message via the template data.
