Conversation
… for block plumbing Replaces the BlockInfo union's isBlockContainer/childContainer/blockContent shape with block/content/children, and annotates it with the facts callers kept re-deriving by hand: contentStart/contentEnd, childrenStart/ childrenEnd, contentKind (read off the spec config stored on the node), and isContentEmpty. The +1/-1 position arithmetic around content edges, tables and child ranges moves into blockEdgePos/blockEdgeSelection/ tableContentCaretPos and the ChildrenInfo fields. The six producers collapse to four named by the input you already have: getBlockInfoFromNode, getBlockInfoAt, getBlockInfoNearPos, getBlockInfoFromSelection. Block navigation (parent/prev/next/last- descendant) joins them here instead of living beside the merge command. All block manipulation (insert/move/nest/replace/split/update, selections, clipboard, serialization, conversions, keyboard shortcuts) is rewired onto the new vocabulary. insertBlocks gains "first-child"/"last-child" placements resolved through getInsertionPos, shared with the move commands so "can this block go here?" has one schema-driven answer; hand-written nodes are checked against their declared content kind when the schema is built (checkNodeMatchesConfig).

TypeCellOS BlockNote moveBlocks.ts flattenColumns getSelection column nodeToBlock
💡 Result:
In the TypeCellOS BlockNote codebase, the components you referenced relate to internal block manipulation logic, specifically for handling structural blocks like columns and nested content [1][2][3]. flattenColumns The flattenColumns function is a utility defined in the moveBlocks.ts file [1]. Its purpose is to process a list of blocks and replace any columnList blocks with their nested children (the contents of the columns) [1]. This ensures that when blocks are moved (e.g., via drag-and-drop or keyboard shortcuts), the structural "wrapper" nodes are unwrapped, effectively moving the content blocks themselves rather than the column structure [1][4]. moveBlocks.ts This file manages the logic for moving blocks within the editor [1][5]. Key aspects include: - It uses a transaction-based approach to ensure that removing blocks and inserting them at a new location occurs as a single atomic operation [1][5]. - It utilizes flattenColumns to handle columnList blocks during the move process [1]. - Recent updates have refined how column structures are handled to prevent errors when a move leaves a column empty [5]. Specifically, moveBlocks no longer automatically triggers a column-fixing function that previously caused errors by dissolving columns mid-move [5]. getSelection The editor's getSelection method is used to retrieve the currently selected blocks [1]. Within the context of block movement, auxiliary functions like getBlockSelectionData and updateBlockSelectionFromData are used to capture the selection state (such as text cursor position or cell offsets) before a block is moved and restore it afterward [1][6]. nodeToBlock The nodeToBlock function is responsible for converting Prosemirror nodes into the BlockNote Block format used by the API [2]. It verifies that a node is a bnBlock, extracts its attributes, and recursively converts child nodes into Blocks, which is how complex structures like nested blocks or columns are represented in the BlockNote data model [2][3][7]. column Columns in BlockNote are managed via the @blocknote/xl-multi-column extension [7][8]. In the internal data structure, columnList nodes act as containers for column nodes, which in turn contain standard block containers [3][7][9]. This structure is part of the bnBlock group, allowing it to be integrated into the standard block manipulation lifecycle [3].

Derive MovedBlock from the flattened selection.
When a selection spans columns, getSelection can return column blocks. moveBlocksUp and moveBlocksDown validate those blocks as column, but moveBlocks inserts flattenColumns(blocks) as blockContainer children. getInsertionPos may therefore reject a valid destination, causing the move to do nothing. Apply flattenColumns before deriving MovedBlock, while retaining the original blocks for removal.

Map anchor positions from the step count on entry.
blockInfo already reflects caller steps. Map its positions with tr.mapping.slice(stepsBefore), as removeAndInsertBlocks does. Otherwise, a table update on a transaction with prior steps can map the anchor twice, causing restoreCellAnchor to inspect a non-table node and return false.

Use contentKind for this branch.
checkNodeMatchesConfig rejects non-canonical static expressions, but it skips validation for function-valued Tiptap content. A custom node can therefore resolve to a semantically equivalent expression that is not "tableRow+" or "". The branch then selects the generic text position instead of the table caret or node selection. Use bottomNestedPrevBlockInfo.contentKind for both checks.

ProseMirror content expressions grammar parentheses quantifiers equivalent text* (text)*
💡 Result:
In ProseMirror, content expressions are used to define the valid sequence and structure of child nodes for a given node type [1][2]. The expressions text* and (text)* are functionally equivalent [1][2]. In both cases, the asterisk () is a quantifier meaning "zero or more" of the preceding element [1][2]. 1. text This expression applies the "zero or more" quantifier directly to the node type text [1][2]. 2. (text)* This expression uses parentheses to group the node type text before applying the "zero or more" quantifier [1][2]. Parentheses in ProseMirror content expressions are primarily used to group expressions—often when using the pipe (|) operator for a choice between multiple options—allowing a quantifier to be applied to the entire group [1][2]. For example, (paragraph | blockquote)+ requires one or more instances of either a paragraph or a blockquote [1][2]. When wrapping a single node type like text, the parentheses do not change the meaning of the expression [1][2]. ProseMirror supports several standard quantifiers [1][2]: - +: One or more - *: Zero or more -?: Zero or one - {n}: Exactly n - {n,}: n or more - {n, m}: Between n and m (inclusive) The order of elements in a content expression is significant, as it defines the permitted sequence of children [1][2]. When multiple choices are provided (using the | operator), the order can also influence matching behavior during schema compilation [1][2].

Avoid rejecting semantically equivalent content expressions.
checkNodeMatchesConfig runs during block-spec creation and can throw for a valid hand-written node. For example, content: "(text)*" is equivalent to the expected "text*" for a plain block, but the raw strings differ. Use semantic expression validation or downgrade this check to a development-time warning.

Summary
Reworks
BlockInfointo a single, uniform vocabulary for reading and writing blocks in ProseMirror positions, removing most of the manual+1/-1position arithmetic sprinkled across the codebase.New BlockInfo model
BlockInfois now a discriminated union over what a block contains:block— wrapper-level info (block,children)content/hasContent— addscontentStart,contentEnd,contentKind(read from the node spec viaNodeSpec.blockConfig),isContentEmptychildren— addschildrenStart/childrenEnd(ChildrenInfo)Producers reduced 6 → 4
getBlockInfoFromNode,getBlockInfoAt,getBlockInfoNearPos,getBlockInfoFromSelectiongetParentBlockInfo,getPrevBlockInfo,getNextBlockInfo,getLastDescendantBlockInfoblockEdgePos/blockEdgeSelection/tableContentCaretPoshelpers replace hand-rolled table caret arithmetic intextCursorPosition.tsNew insertBlocks placements
insertBlocksnow supports"first-child"and"last-child"in addition to"before"/"after", via a sharedgetInsertionPoshelper that descends into wrapper blocks as needed.NodeSpec.blockConfig
Block specs now attach their resolved
BlockConfigonto the TipTap node spec (extendNodeSchema), so low-level code can readcontentKindfrom the schema instead of re-deriving it by string-matching node names. Hand-written nodes (viacreateBlockSpecFromTiptapNode) are validated withcheckNodeMatchesConfig.Adopted across the codebase
