- Added: Vector Expressions block format added to the Rich Text toolbar.
- Added: Expression pill editing popover with syntax highlighting.
- Added: Server-side parsing and evaluation engine for expressions.
- Added: Logic panel in block inspector for visibility and class expressions.
-
Added: Live preview evaluation via REST APIs.
-
Changed: Changed the core expression pill HTML tag from <mark> to <span>.
-
Fixed: Expression format now appears in core Button blocks and other blocks using withoutInteractiveFormatting. Removed interactive: true from format registration.
- Fixed: Pressing Escape while editing an expression in the popover now reliably closes it.
- Fixed: Custom vector/button block now allows all registered rich-text formats (was allowedFormats={[]}).
-
Fixed: render_block_logic: attrs is now always initialized as an empty array and guarded with is_array() before iteration.
-
Features: Mustache-style expression syntax — Embed {{ expression }}, {{{ raw }}}, and {{– comment –}} tokens directly inside any block’s text content. Evaluated server-side on every render.
- Features: Dot-notation data access — Access WordPress data with simple, readable paths: post.title, user.name, site.name. No need to know internal WordPress property names like post_title or display_name.
- Features: Post, User & Site context roots — Three built-in data roots cover the most common dynamic content needs out of the box.
- Features: Custom field (meta) access — Read any post or user meta field with post.meta.my_key or user.meta.my_key.
- Features: Full expression language — Supports arithmetic (+, -, *, /, %), comparison (==, !=, >, <), logical operators (&&, ||), ternary expressions (condition ? a : b), dynamic bracket access (post[“title”]), and inline string interpolation (“Hello {user.name}”).
- Features: Built-in filters (pipes) — Transform values with a chainable filter syntax: upper / uppercase, lower / lowercase, upper_first / capitalize, truncate, trim, replace, kebab, default, if, match, map, join, prop / get, get_post, get_user, get_meta, date, esc_html, esc_attr, raw, and render.
- Features: Block visibility control — Every Gutenberg block gains a Vector Logic panel. Set show/hide conditions with an expression evaluated per-render.
- Features: Dynamic CSS class — Append CSS classes to any block’s root element based on an expression result.
- Features: In-editor autocomplete — Typing {{ in the block editor triggers a smart autocomplete dropdown with categorised expression suggestions, icons, and preview snippets.
- Features: In-editor expression chips — Inserted expressions are rendered as interactive inline chips in the editor, allowing quick edits and previews without hunting for raw text.
- Features: Excerpt rendering — Expressions in post content are evaluated before WordPress generates post excerpts, ensuring clean, parsed output in archive loops and REST responses.
- Features: Extensible via hooks — Register custom data roots, custom filter functions, custom autocomplete completions, and more via standard WordPress filters and JavaScript hooks.
-
Features: WP_DEBUG error comments — When debug mode is active, parse errors are surfaced as HTML comments (<!– VE Error: … –>) for easy troubleshooting.
-
Added: prop / get filter — Access a property on the result of a pipeline filter without needing parentheses. {{ post.id | get_post | prop ‘post_title’ }} is now equivalent to {{ (post.id | get_post).post_title }}.
- Added: truncate filter — Limit a string to N characters with an optional suffix (default …). Supports named args: {{ post.excerpt | truncate length=120 suffix=’…’ }}.
- Added: trim filter — Strip whitespace or a custom character set: {{ value | trim }} / {{ value | trim ‘/’ }}.
- Added: replace filter — Find-and-replace: {{ post.title | replace ‘Old’ ‘New’ }} or with named args search= / replace=.
- Added: upper_first / capitalize filter — Uppercase the first character only: {{ post.title | capitalize }}.
- Added: kebab filter — Convert a string to a URL-safe kebab slug via WordPress’s native sanitize_title(): {{ post.title | kebab }}.
- Added: Filter aliases — uppercase (→ upper), lowercase (→ lower), capitalize (→ upper_first) for more readable expressions.
- Added: Keyword meta deny list — ObjectProxy and get_meta now block meta keys containing sensitive substrings (pass, token, secret, api_key, auth, nonce, salt, credential, private_key) as a defense-in-depth layer beyond is_protected_meta(). The list is filterable via vector_expressions/security/sensitive_meta_keywords.
- Added: vector_expressions/error action — Fires on every expression evaluation failure. Allows production error tracking (logging, Sentry, etc.) without exposing details in the frontend HTML.
-
Added: vectorExpressions.logicPanel.sections JS filter — Extension point for adding custom sections to the Vector Expressions inspector panel from JavaScript. Used by Pro to inject Dynamic Bindings UI.
-
Fixed: render_block_logic: attrs is now always initialized as an empty array and guarded with is_array() before iteration.
