novident_project_manager 1.0.1

Dart for `.nov` projects to manages: binder tree, rich-text content, layouts/formats, writing sessions, targets, snapshots and git"

Novident Project Manager

The Dart package that owns the .nov schema and drives a Rust engine for writing projects: binder tree, rich-text content, layouts/formats, writing sessions, targets, snapshots and git.

Dart (schema owner)  ⇄  JSON boundary  ⇄  Rust engine (I/O, git, search, diff, snapshots, validation)

• Dart owns the schema: typed models, tolerant codecs, stores, schema registry + migration, the binder reducer and the Layout/editor → AST parsers.
• Rust is schema-agnostic: verbatim file I/O, structural validation (via schema-v1.yaml), search, text diff, git and snapshots.
• EngineClient is the only importer of the generated FRB bindings.

Important

By now the Backups feature is still being implemented. Snapshots are the safe alternative to work with.

Table of contents

Understand the project

• ARCHITECT.md — end-to-end architecture (Dart ⇄ Rust, boundary, testing).
• docs/engine.md — the Rust engine: modules, JSON boundary, how to extend.
• docs/project-format.md — the .nov format, file by file.
• docs/getting-started.md — setup, codegen, build, run tests.

Use the API

• docs/stores-and-reducer.md — stores/I/O interfaces and reducer ops.
• docs/models.md — every schema class and codec.
• docs/parsers-to-ast.md — Layout/editor → AST parsers (usage + output formats).
• docs/placeholders.md — the <$…> placeholder tokens.

What you can do with ProjectManager

ProjectManager (see lib/src/project_manager.dart) is the single entry point. Everything is lazy and typed; operations persist only the affected files.

Lifecycle & stores

Area	Getter / methods	What it gives you
Engine	engine	Low-level typed access (search, git, snapshots, validation, raw I/O)
Binder	binder	The Folder tree + header; load/persist, lookup & external files
Content	documents	Per-node editor content: lazy LRU cache, debounced writes
Compiler	formats	Formats and their layouts (resolved by id, lazily)
Exports	exports	Records of performed exports
Sessions	sessions	Day-by-day writing-session history

Binder (tree) operations

createDocument, createFolder, renameNode, moveNode, trashNode, restoreNode, purgeNode (deletes document dirs too). Mutations go through BinderActions with cycle guards and trash semantics, then persist the binder (recomputing the lookup).

final doc = await manager.createDocument('draft-id', 'New chapter');
await manager.renameNode(doc.id, 'The Final Chapter');
await manager.moveNode(doc.id, 'trash-folder-id');   // → Trash

Node content

nodeContent/setNodeContent (editor Document), nodeSynopsis/ setNodeSynopsis, nodeNotes/setNodeNotes, nodeComments/setNodeComments.

Metadata & statistics

readMetadata migrates old schema versions automatically. Update blocks with updateProject, updateAuthor, updateBook, updateCompileDefaults, updateEditorPreferences, updateSessionState; recompute region word counts with recomputeStatistics({wordsByNodeId}) (never gated).

Writing sessions (history)

Open or continue today's session without duplicates (SessionHistory), adjust counts incrementally from an external counter service, and close with a full recount gated by compute_count_on_close_session:

await manager.adjustOpenSession(
  DateTime.now().toUtc(),
  author: 'Elena',
  adjustment: const CountAdjustment(words: 12, characters: 64),
);
await manager.closeWritingSession(DateTime.now().toUtc(), author: 'Elena');

See docs/stores-and-reducer.md for the session decision flow, and docs/placeholders.md for tokens the compiler understands.

Targets

Per-node and global writing targets (target.index.json):

final targets = await manager.resolveTargets();
final goal = targets.targetOf('chapter-1');          // override or inherited
final inFolder = targets.targetsWithinFolder('part-1');

await manager.updateGeneralTarget(const TargetGeneral(target: 50000));
await manager.setNodeTarget('chapter-1', const TargetFile(words: 5000, characters: 27000));
await manager.removeNodeTarget('chapter-1');

Snapshots & git

Snapshot with a metadata version bump (saveProjectSnapshot), list, restore and delete; plus full git: branches, fetch, conflicts, content/commit diffs and remotes:

final snapshot = await manager.saveProjectSnapshot();
await manager.deleteSnapshot(snapshot.id);

await manager.gitInit();
await manager.gitBranchCreate('revision-2');
await manager.gitBranchSwitch('revision-2');
final conflicts = await manager.gitConflictDetect();
await manager.gitSetRemote('origin', 'https://example.com/repo.git');
print(await manager.gitRemotes());

Search

Quick (search), structural/full (searchFull) and index maintenance (reindexSearch, searchStatus).

Example (end to end)

import 'package:novident_project_manager/novident_project_manager.dart';

Future<void> main() async {
  // Create a project (skeleton + .gitignore + git init).
  final manager = await ProjectManager.create('/path/to/my-book.nov', name: 'My Book');

  // Build a bit of binder structure.
  final root = (await manager.binder.load()).root;
  final draft = await manager.createFolder(root.id, 'Draft', folderType: FolderType.manuscript);
  final chapter = await manager.createDocument(draft.id, 'Chapter 1', section: 'chapter');

  // Set rich-text content (an editor Document).
  // await manager.setNodeContent(chapter.id, editorDocument);

  // Track a writing day and targets.
  final targets = await manager.resolveTargets();
  print('target words: ${targets.targetOf(chapter.id)?.words}');
  await manager.closeWritingSession(DateTime.now().toUtc(), author: 'Elena');

  // Version it.
  await manager.gitCommit('Chapter 1 draft', authorName: 'Elena', authorEmail: '[e-mail]');
  await manager.saveProjectSnapshot();

  await manager.dispose();
}

ProjectManager/EngineClient need the compiled native library, so this demo runs inside the app — not under flutter test. Pure logic (codecs, reducer, session math, parsers) is fully unit-tested.
