eCodeMirror (CodeMirror 6) for Evolution CMS

Modern CodeMirror 6 editor package for Evolution CMS 3.5.x. This package replaces the legacy CM5 plugin with a Composer‑installed, publishable, and extensible CM6 implementation.

Requirements

• PHP ^8.3
• Evolution CMS ^3.5.2
• Composer 2.2+

Install

composer require evolution-cms/ecodemirror "*"

Register editor (optional auto‑set):

php artisan vendor:publish --tag=ecodemirror-config

Publish assets:

php artisan vendor:publish --tag=ecodemirror-assets

What gets published

• Config (single source of truth):
  • core/custom/config/cms/settings/eCodeMirror.php
• Assets:
  • public/assets/plugins/eCodeMirror/dist/eCodeMirror.js
  • public/assets/plugins/eCodeMirror/dist/eCodeMirror.css

System Settings (Overrides)

These are overrides only. The canonical config is core/custom/config/cms/settings/eCodeMirror.php.

• ecm_profile
• ecm_theme_mode (auto/light/dark)
• ecm_theme
• ecm_font_size
• ecm_line_height
• ecm_line_wrapping
• ecm_emmet
• ecm_search

Config structure (publish config)

Key sections:

• profiles — preset options + extensions
• contexts — map context → profile
• themes — light/dark theme mapping
• editor — base options (font, line height, history/state, gutters, keymap)
• extensions — global feature toggles
• protected_keys — options not overridable via params

Manager Events

Editor is wired into manager form events:

• OnDocFormRender
• OnTempFormRender
• OnChunkFormRender
• OnSnipFormRender
• OnPluginFormRender
• OnModFormRender
• OnTVFormRender
• OnRichTextEditorInit

Build (development only)

Node is required for development builds. In production, use published public/dist.

npm install
npm run build

Build output:

• public/dist/eCodeMirror.js
• public/dist/eCodeMirror.css

Notes

• Assets are cache‑busted via ?v=<mtime> fallback.
• Legacy CM5 plugin must be disabled when enabling eCodeMirror.
• Emmet is enabled via profile extensions (emmet), lint currently provides JSON validation when lint is enabled.
• For resource content, eCodeMirror activates only when richtext is disabled (no RTE), matching legacy behavior.
• If you previously published core/custom/config/cms/settings/which_editor.php, remove it to avoid forcing eCodeMirror as the RTE.
