* Include two versions of Marked.js
* Include two versions of Marked.js
* Working two different render pipelines
Adds stylesheet "styleLegacy.less"
Adds markdownHandler "markdownLegacy.js"
The BrewRenderer will switch between these and the new pipeline dependent on the "version" prop passed in.
* Mustache-style div blocks
* Legacy snippets & columnbreak
* Codemirror styling for Div Blocks
* Lint
* Codemirror highlights for inline Divs as well
These will turn red `{{class Content}}`
Multi-line divs will turn purple
```
{{class,class2
content
}}
```
No real need for these to be different colors. Just for testing.
* More lint
* Update dependencies.
* Adding Button to switch render pipelines
* Update Marked.js
* Popup alert to refresh page when renderer changed
* Don't compress files in Development (very slow)
* Block DIV or inline Span depending on {{ placement
* \column emits a Div instead of Span
* Allow share page to use new renderer
* {{ divs no longer need empty lines. Spans work in lists.
* Typo
* Typo
* Enforce \page must be at start of line. Code cleanup.
* Inject newlines after/before {{/}} to avoid needing blank lines
* Fixes issues with tables.
* Remove console.log
* Fix spacing issue for Spans
* Move things from Brewrenderer to Markdown
Try to keep all custom text fiddling in one spot.
* Rename variables
* Update Font-Awesome to v5.15. Fix style issues on popups.
* Update {{ Divs/Spans, Fix nested hilighting
* Fixed Spans/divs with no tags or just commas
* Use blacklist for {{ to allow more characters
* Update package-lock.json
* Update all icons to Font-awesome 5
* V3 hidden behind config variable
Add "globalThis.enable_v3 = true" in the console to enable.
* lint
* Give user styles higher priority to still allow overrides
* Apply style priority to *all* user styles
* Change .legacy .v3 to .phb, .phb3
