ianvs_markdown 0.3.1

Safe-by-default Markdown rendering and live-editing widgets for Flutter.

0.3.1

• Add opt-in IanvsMarkdownSyntaxPreset.standard to the standalone IanvsMarkdown renderer for standard GFM messages. It skips Obsidian syntax, math, HTML controls, and source projections while keeping the existing Obsidian preset as the default.
• Preserve host styles, selection, clipboard, link/image callbacks, custom syntax and builders, and code/Mermaid hooks in the standard preset. Standard image alt text is forwarded unchanged, and images remain blocked by default.
• Add the same syntaxPreset option to scanMarkdownForRendering, so literal dollar signs do not consume math syntax budget in the standard preset.
• Include a versioned standard-syntax fixture contract and regression coverage for literal metadata, GFM behavior, resource policy, host hooks, changing source/presets, copy, and exact budget boundaries.
• Exclude the app-dependent layout integration test from the library archive, alongside the already-excluded standalone application.
• Require flutter_markdown_plus ^1.0.12, the verified dependency baseline; version 1.0.7 fails existing link layout and nested task interaction tests.

0.3.0

• Let both the standalone renderer and Reading view select across the complete document and handle Cmd+A / Ctrl+A; copying a whole-document selection now publishes exact Markdown as text/plain and sanitized semantic HTML as text/html.
• Preserve block and inline Markdown semantics, together with matching rich HTML, when a partial Reading-mode mouse selection crosses rendered blocks.
• Render safe HTML meter indicators, ruby annotations, fieldsets, radio groups, range sliders, and text, number, password, date, time, and temporal inputs with Obsidian-compatible behavior.
• Add controller-driven heading navigation across Reading, Live Preview, and Source modes, including distant virtualized blocks and folded ancestors.
• Let markSaved(savedText: ...) record the exact persisted snapshot so edits made during an asynchronous save remain dirty.
• Add optional placeholder text to Live Preview and Source editors, and prevent editing shortcuts from modifying documents in Reading mode.
• Keep tables rendered while editing cells and target cell content directly when focusing or navigating between cells.
• Improve heading, quote, list, code, inline math, and metadata alignment; stabilize nested list guides during scrolling and hide inactive inline code delimiters.
• Preserve rendered links until their source is selected, correctly hide front matter when disabled, and retain source identities across theme changes.
• Avoid duplicate widget keys when a document repeats inline HTML controls.
• Exclude the standalone Linefold desktop application from the published library archive; its source remains available in the repository.

0.2.0

• Start a new source list block when an unordered bullet changes between -, *, and +, or an ordered delimiter changes between . and ), while keeping same-delimiter siblings grouped.
• Keep loose lists structurally continuous across blank-separated siblings and indented child blocks, including marker-only items, visual-column Tab continuations, per-item Live Preview editing, and nested guide depth.
• Recognize one to three spaces followed by a Tab as four-column indented code, including after list or quote container projection, so Obsidian comments, footnotes, and block IDs inside remain byte-exact literal text.
• Keep pipe-less GFM body rows inside tables until a blank line or real block opener, including exact Live Preview cell editing and missing-cell writes.
• Keep irregular-table projection active after fenced code nested in list containers, while leaving table-shaped lines inside that code byte-exact.
• Preserve footnote, comment, and block-ID-shaped text inside code blocks that begin in ordered, unordered, empty, nested, quoted, or tab-separated list items, with container prefixes excluded from exact UTF-16 source ranges.
• Preserve footnote, comment, and block-ID-shaped text inside fenced or indented code nested in one or more block-quote containers, with original UTF-16 source ranges shared by Reading, Live Preview, and source styling.
• Keep inline and standard footnote-shaped text literal inside true indented code blocks, excluding it from Reading expansion, shared ordinal collection, Live Preview presentation ranges, and source metadata styling.
• Keep trailing and table-cell-shaped ^block-id text literal inside inline, fenced, and true indented code blocks across Reading, source styling, and Live Preview.
• Collapse the leading ^ of valid block IDs in inactive and active Live Preview while keeping the identifier visible and preserving the complete source character in exact caret, word, and physical-line selections.
• Prevent comment-shaped text inside inline, fenced, or indented code from prematurely closing an outer Obsidian comment; source styling and Reading now consume the complete outer range.
• Preserve literal %%comment-shaped%% text inside true four-space or tab indented code blocks in Reading and source styling, without treating an indented paragraph continuation as code.
• Keep a line-ending ^block-id candidate literal when a soft line below continues the same Markdown block; only a true block-ending marker is consumed or styled as Obsidian metadata, while table-cell IDs stay intact.
• Resolve empty ordinary-link destinations to Obsidian's current-note URI in link callbacks, including both () and (<>) source forms.
• Keep defined, undefined, and inline footnote markers byte-exact in inactive Live Preview, while definition blocks retain their labels without definition punctuation and activation restores the complete Markdown source. Reading mode alone renders the shared [N] / [N-k] sequence; single- and multi-line code spans retain literal footnote-shaped text in both modes.
• Map inactive blockquote and ATX-heading text clicks past hidden > / # prefixes before the block becomes editable, preserving Obsidian's exact source caret, word selection, and raw-marker triple-click line selection.
• Keep an isolated ==before / blank line / after== attempt fully literal in Reading and inactive Live Preview instead of projecting both sides as independent unclosed highlights; exact source and higher-priority literal contexts remain unchanged.
• Parse Obsidian angle scheme and email autolinks before the safe raw-HTML fallback, preserving <https:…>, <[e-mail]>, mailto, ftp, and obsidian targets in Reading and exact-source Live Preview.
• Match Obsidian's non-standard <www…> fallback by preserving the leading < as literal text while including the trailing > in the bare-link label and percent-encoded destination; ordinary www links remain unchanged.
• Preserve Obsidian inline-link destination backslash parity: odd runs that escape a parenthesis now retain one encoded literal backslash per preceding pair in Reading and inactive Live Preview, while exact source, code, comments, images, angle destinations, titles, and malformed links stay unchanged.
• Keep ordinary full-reference labels case-insensitive while matching Obsidian's measured non-normalizing whitespace boundary: a secondary label combining surrounding whitespace with a repeated internal run remains literal in Reading and block-local Live Preview instead of resolving.
• Add Obsidian-style Live Preview property editing for text fields and boolean controls: Enter or focus loss commits one undoable source edit, Escape cancels pending text, and a committed text field canonicalizes top-level inline scalar lists to the block-list form emitted by Obsidian Properties.
• Add finite numeric property input with focus-loss submission, invalid-input recovery, numeric YAML type preservation, and the same observed top-level flow-list canonicalization as an Obsidian number-field commit.
• Add safe in-place tag editing for complete string lists: chip removal writes immediately, removing the last item preserves an empty tags: property, and Tab/Enter adds a block-list value from either populated or empty state. Typed, nested, truncated, or oversized lists remain source-only.
• Add neutral editable alias chips for complete string sequences. Removing an alias immediately rewrites safe flow lists, removing the last item preserves aliases:, and Tab/Return add block-list aliases from empty or populated properties while retaining existing item order. Focus loss and Escape commit pending aliases, surrounding spaces are trimmed, and exact duplicates are not appended.
• Add in-place property-key renaming with Tab, Enter, and focus-loss commits, Escape cancellation, exact source-order and value-type preservation, YAML quoting for ambiguous names, and empty/case-insensitive duplicate/lossy-key rejection, including Obsidian's refusal of case-only renames.
• Add a segmented year/month/day property editor with a date-picker surface. Return commits an exact valid date as one undoable edit and canonicalizes top-level flow lists; Tab moves focus while retaining the pending UI value.
• Match Obsidian properties for source-order keys, an ordinary title row, default-expanded panels, triple-dash-only closing markers, distinct aliases, tags, and cssclasses, linked Wiki/URL scalar values, and invisible empty mappings across Reading and Live Preview without turning their delimiters into thematic rules.
• Lock Obsidian list editing semantics for multi-level empty-item exits, quote-contained soft continuations, four-space and tab-indented list-like lines, standalone comment wrappers, and tab-separated dash markers that render as lists while retaining native newline input behavior.
• Match Obsidian ordinary-link source recognition for empty and angle-wrapped destinations, balanced and escaped parentheses, double-, single-, and parenthesis-delimited titles, soft-line title whitespace, malformed-link fallback, nested labels, and parser-compatible full-reference labels; share the same scanner with block-local reference-definition injection.
• Match Obsidian Callout headers for case-insensitive non-empty types up to ], Unicode and punctuation fallback cards, strict zero-or-one-space quote markers, real-blank block boundaries, exact active source markers, and spaced nested block-quote rails.
• Match Obsidian emphasis and strong delimiter stacks for flanking, asymmetric and long runs, Reading/Live Preview-specific surplus presentation, intraword asterisks, literal intraword underscores, escapes, nesting, and source-range selection.
• Match Obsidian strikethrough parsing for double-tilde-only syntax, odd and even delimiter runs, asymmetric and adjacent surplus, whitespace and escape boundaries, soft-line and unclosed scopes, nested links/Wiki aliases, code priority, inactive marker hiding, and source-range selection.
• Match Obsidian highlight parsing for whitespace boundaries, surplus and adjacent = runs, escape parity, closed soft-line spans, unclosed line scope, nested links, Reading/Live Preview presentation, and source-range selection.
• Match Obsidian tag tokenization for Unicode and emoji, numeric rejection, slash paths, adjacent tags, punctuation boundaries including a confirmed fullwidth-colon start, and backslash parity with code, comment, and link precedence across Reading, Live Preview, and source styling.
• Match Obsidian block-ID boundaries for standalone markers, underscores, table cells, ASCII spaces after valid IDs, multiple candidates, escape parity, blank-separated ownership by the preceding supported block, and code precedence across Reading, Live Preview, and source styling.
• Match Obsidian comment pairing, backslash escape parity, adjacent-percent residue, literal unclosed delimiters, code precedence, and standalone comments that remain one editable Live Preview block across blank lines.
• Match Obsidian case-insensitive standard-footnote definitions by making the last duplicate authoritative in Reading while preserving exact Live Preview and source bytes, shared first-reference numbering, [N-k] repeat labels, in-page link callbacks, and every backlink.
• Match Obsidian's Live Preview inline-source boundaries: reveal delimiters at their opening edge, hide them immediately after the closing edge, select the complete formatted source on double click, edit ordinary links without navigating, and route Wiki-link clicks through the host navigation callback.
• Keep Live Preview selection document-wide: Command+A selects the complete Markdown source, while desktop mouse drags extend forward or backward across rendered block boundaries without marking the document dirty.
• Match Border's one-pixel nested-list indentation guides and 28 px marker steps in Reading and Live Preview, including active and split list items.
• Match Obsidian image dimensions for standard Markdown images, external images, and host-resolved Wiki image embeds while preserving safe default image blocking and exact Live Preview source editing.
• Add Obsidian-style desktop image resize handles in Live Preview with aspect-ratio preservation, editor-width clamping, width-only source writeback, double-click reset, and independent undo steps.
• Match Obsidian table row and column drag handles, 27 px Live Preview rows, point-accurate first-click caret placement, selection and drop feedback, RTL geometry, mobile active-handle visibility, structural source normalization, and the minimum-width alignment markers it emits.
• Match the active Border theme's fenced-code dot texture, dashed frame, dimensions, light and dark syntax palettes, persistent copyable Live Preview flair, desktop and mobile reading controls, and one-second copy feedback.
• Match Border blockquotes across reading, Live Preview, and source modes with the 4x4 dot texture, 4px radius, inset 3px accent rail, exact outer padding, and Obsidian's 2px horizontal-rule weight.
• Match Border's ordinary task checkboxes with 16px geometry, 6px corners, exact light and dark colors, a two-pixel hover/focus ring, thick check mark, keyboard and semantic toggling, and muted completed text in Live Preview.
• Render Obsidian's full single-character task-state model, including Border's progress, cancelled, forwarding, scheduling, question, importance, star, info, idea, location, bookmark, note, sentiment, quote, savings, and trend icons; preserve every original marker and toggle it with Obsidian semantics.

0.1.0

• Add IanvsMarkdownController with selection, dirty state, formatting commands, and document-wide undo/redo history.

• Add IanvsMarkdownEditor for complete source editing with syntax styling and Markdown-aware list continuation.

• Add IanvsMarkdownLiveEditor with live-preview, source, and reading modes.

• Add source-preserving block parsing, editor toolbar, and keyboard shortcuts.

• Refine live preview to keep active blocks in the rendered typography flow, reveal inline Markdown delimiters only around the caret, and collapse link targets and inline-code delimiters outside full-source mode.

• Edit contiguous lists one item at a time, toggle task checkboxes in place, edit GFM table cells without exposing pipe syntax, append rows and columns from contextual table-edge controls, and focus the newly created cell.

• Navigate table cells with Tab, Shift+Tab, arrow keys, and boundary-aware left/right movement; Enter or Tab from the last cell appends a row, while Shift+Tab from the first cell inserts a row above the table header.

• Render completed task text with a strike-through and continue completed tasks as fresh unchecked items when Enter is pressed.

• Keep task markers concealed while an item is active, retaining an interactive checkbox beside the editable text without changing the underlying source.

• Keep bullets, ordered numbers, and quote rails rendered while their blocks are active, concealing the corresponding Markdown prefixes on every line.

• Preserve the original caret or selection through Tab/Shift+Tab indentation instead of selecting the entire transformed line.

• Use a unified active surface for fenced code blocks and apply language-aware highlighting while preserving editable fences and exact source offsets.

• Render Obsidian Wiki links, tags, highlights, typed/foldable callouts, comments, block identifiers, and inline footnotes while preserving their exact source in editing modes.

• Make outline navigation reach distant headings that have not yet been built by the lazily rendered live-preview list.

• Extract the reusable Markdown renderer from ianvs-acp.

• Add safe image placeholders, fenced-code tools, front matter, and outline navigation.

• Add rendering budgets and custom builder injection points.
