Tom Basics — the foundation layer of the Tom framework

> Tom Basics is part of the Tom framework by al-the-bear. > Distributed under the terms in each package's own license — see > LICENSE.md.

A small family of focused, dependency-light Dart packages that every other Tom component builds on: exception handling with traceable IDs, platform and console utilities, networking, the unified CLI / build framework (tom_build_base) and the buildkit build orchestrator that runs on it (tom_build_kit), cryptography, a unified messaging API, and a handful of documentation / workspace tools.

This document is the map. It orients you to the whole tom_ai/basics repository and routes you to the one package you actually need — each package carries its own README with the full manual, and the runnable samples live in tom_basics_samples/. Depth lives downstream; this page is just the index.

New here?

Start with the tom_basics_sample project — it walks the exception-handling-with-UUID-tracking model end to end and is the gentlest on-ramp into the ecosystem. From there, the samples learning path takes you category by category.

What you can do with Tom Basics

• Track every failure to its source — wrap and rethrow exceptions carrying

a stable UUID so a log line on one machine maps to a stack frame on another. - Write code that runs the same on console and in the browser — platform detection, console output, and an HTTP client that abstract the host away. - Talk to flaky networks reliably — HTTP retry with backoff and local server discovery. - Build your own CLI tools in minutes — declare a tool, its commands and options once and get argument parsing, help, workspace traversal, pipelines and config for free (tom_build_base). - Drive the whole workspace from one command — buildkit runs cleanup, versioning, compile, dependency resolution, publishing and git workflows as composable pipelines across every package (tom_build_kit). - Secure your data — issue and verify JWTs, hash and check passwords, and do RSA round trips. - Send a message anywhere — one chat API over Telegram, WhatsApp, Signal and more. - Keep generated docs and workspace metadata honest — non-destructive Markdown merges, workspace package scanning, and key generation.

How the packages fit together

Tom Basics splits into five concern areas. Read this framing before the component tables so the inventory makes sense:

• Core utilities — the universally-imported primitives: error model,

platform/console helpers, networking. Almost everything depends on these. - Build framework — tom_build_base is the shared engine behind every Tom CLI tool (buildkit, testkit, issuekit, …); tom_build_kit is the buildkit orchestrator built on it — the one package here that ships binaries; tom_analyzer_shared is the analyzer-summary cache that code generators sit on. - Crypto — security primitives, isolated so non-security code never pulls in the crypto dependency tree. - Messaging — a transport-agnostic chat abstraction. - Doc / workspace tooling — utilities that operate on the workspace itself: Markdown merge, package scanning, key generation.

Components

Every package appears in exactly one row below, linked to its own README. Only tom_build_kit ships standalone binaries (buildkit, findproject); the rest are libraries (tom_build_base and tom_tools ship their executables through the consuming CLI tools, not from here), so their Binary column is —.

Core utilities

Package	What it is	Binary
tom_basics	Basic utilities including exception handling with UUID tracking.	—
tom_basics_console	Console / standalone platform utilities — platform detection, console output, HTTP client.	—
tom_basics_network	Network utilities — HTTP retry and server discovery.	—

Build framework

Package	What it is	Binary
tom_build_base	Unified CLI framework: workspace traversal, tool definition, pipeline execution, build configuration.	—
tom_build_kit	Build orchestration with pipelines — cleanup, versioning, compile, dependencies, publish and git workflows.	buildkit, findproject
tom_analyzer_shared	Shared analyzer-summary caching reused by Tom code generators (reflection, d4rt bridges).	—

Crypto

Package	What it is	Binary
tom_crypto	Cryptographic utilities — JWT tokens, password hashing, RSA encryption.	—

Messaging

Package	What it is	Binary
tom_chattools	Unified chat API for Telegram, WhatsApp, Signal and other messaging platforms.	—

Doc / workspace tooling

Package	What it is	Binary
tom_markdown_merge	Non-destructive, headline-aware Markdown region merge (managed / override / preserved).	—
tom_package_scanner	Scans workspace repos and derives each Dart package's publication status, license, version and links.	—
tom_tools	Key-generator CLI built on tom_crypto.	—

Getting started

Add the package you need with its hosted version constraint (never a path override):

dependencies:
  tom_basics: ^1.0.0

dart pub add tom_basics

A minimal taste — wrap a failure with a traceable ID:

import 'package:tom_basics/tom_basics.dart';

void main() {
  try {
    throw StateError('disk full');
  } catch (e, s) {
    final tracked = TomException.wrap(e, s);
    print(tracked.id); // e.g. 3f2a9c41-... (stable UUID for cross-host tracing)
  }
}

Each package README opens with its own runnable quick-start — follow the link from the component tables above.

Samples learning path

Runnable, article-grade sample projects live in tom_basics_samples/, one self-contained Dart package each. Ordered from first contact to advanced framework use:

#	Sample	Demonstrates
1	tom_basics_sample	Exception handling + UUID tracking, end to end.
2	tom_basics_console_sample	Platform detection, console output, HTTP client.
3	tom_basics_network_sample	HTTP retry with backoff + local server discovery.
4	tom_build_base_introduction_sample	A simple single-command build tool on tom_build_base.
5	tom_build_base_advanced_sample	A nestable, multi-command build tool with options and pipelines.
6	tom_build_base_advanced_analyzer_sample	Analyzer-summary caching with tom_analyzer_shared in a generator-style command.
7	tom_chattools_sample	The unified chat API against a mock transport.
8	tom_crypto_sample	JWT issue/verify, password hash/verify, RSA round trips.

> Samples are written before some of their packages' deep-dive docs; until each > sample project lands, its link is a forward reference resolved by the samples > build-out.
