Front Matter
In which we examine why you would want to use TiddlyWiki, why you would want to learn it from this book, and how the book can teach you TiddlyWiki.
1: The Shape of TiddlyWiki
In which we download and install TiddlyWiki, learn the basics of TiddlyWiki's data model, and begin creating some tiddlers in a sample wiki.
  • Installing TiddlyWiki – How to get TiddlyWiki set up on your computer.
  • Downloading Grok TiddlyWiki – How to make a copy of this book so you can save your progress.
  • The TiddlyWiki Interface – Study an annotated screenshot of TiddlyWiki's interface to help you put names to what you're seeing.
  • Tweaking Your Settings – A quick look at some of the TiddlyWiki options you're most likely to want to change.
  • Tiddlers – Tiddlers are the unit of information in TiddlyWiki.
  • Fields – Tiddlers are made up of fields.
  • Wikitext – Wikitext is a markup language used to format tiddlers.
  • Links – Links tell TiddlyWiki what ideas (tiddlers) in your wiki are related to each other.
  • Tags – Tags are a special type of link used to categorize tiddlers and arrange them in hierarchies.
  • Requirements for the Sample Wiki – What do we want the example wiki we're building in this book to be able to do?
  • Structuring Our Wiki – How to translate what we want the wiki to do into TiddlyWiki concepts.
  • Journal Tiddlers – How to create journal tiddlers and use basic wikitext formatting features.
  • Contact Tiddlers – How to track the people we meet at work, linking to the ideas they're involved in and modeling their attributes as discrete fields of information.
  • Meeting Tiddlers – How to take notes on meetings, excising existing notes and using TiddlyWiki's timestamp format to identify when the meeting happened.
  • Project Tiddlers – How to organize meetings and knowledge into overarching projects.
  • Knowledge Tiddlers – How to organize information that doesn't fall into a clear category, and why such information should be pulled out into separate units of information and related to others.
  • Reviewing the Basics – Some final exercises to help you practice the basics.
2: Filing and Organizing
In which we learn how to create and organize tiddlers in ways that make them easy to find and reuse later.
  • Searching – TiddlyWiki allows fast and convenient full-text searching, although it doesn't look everywhere.
  • Browsing Your Tiddlers – TiddlyWiki provides a variety of options for getting an overview of many tiddlers at once.
  • Tiddler Titles – Carefully naming tiddlers and concepts has many benefits, but is often more art than science.
  • Naming ConventionsNaming conventions are rules about how sets of things should be named. Creating your own conventions will make it easier to create titles and easier to find tiddlers later.
  • Slicing Up Content – We slice content up into tiddlers by modeling nouns related to our subject matter.
  • Creating Hierarchies with a Table of Contents – TiddlyWiki can produce hierarchical tables of contents from tag structures.
  • Ordering Tiddlers – A set of tiddlers, such as those with a particular tag, can be given a specific order using a tiddler list.
  • Creating Evergreen Notes – TiddlyWiki can prevent your old notes from withering and being lost when you use its features appropriately.
3: Filtering and Formatting
In which we learn how to use filters to answer questions about our notes, like “What are the email addresses of all the people who went to X meeting?”, or “At what meetings attended by Jane did we discuss X concept?”. We'll also dig into HTML and widgets, which allow us to create tiddlers that use complex formatting and update automatically when other tiddlers are changed.
  • Filters – Filters are a lightweight query language used primarily to select tiddlers.
  • Using Filter Expressions – Filter expressions, runs, and steps work together to select tiddlers.
  • Anatomy of Filter Steps – Filter steps have operators, suffixes, parameters, inputs, and outputs.
  • Common Filter Operators – A small number of basic filter operators will handle many of your common needs.
  • HTML – HTML is a simple formatting language used to describe web pages, including TiddlyWikis. We can go “down a level” from wikitext to HTML when we need a bit more control over presentation.
  • Widgets – Widgets are a TiddlyWiki extension to HTML exposing wiki-specific functionality.
  • Your First Dynamic List – You can create lists of tiddlers that automatically update to show all the tiddlers that currently match a filter.
  • Comments – You can leave notes to yourself in your wikitext that don't appear in the output.
  • When Things Go Wrong – As your wikitext gets more complicated, it occasionally might not do what you were expecting; here's how you can figure out what you did wrong.
4: Variables, Macros, and Transclusions
In which we study a variety of ways to write some content in one place and reuse it in many other places, a capability which sounds boring but is in fact incredibly powerful and versatile, setting TiddlyWiki apart from the competition.
  • Variables – Variables let you assign a name to an arbitrary value, then use the name in place of the value in multiple places.
  • Macros – Macros extend the concept of variables by allowing portions of the value to change each time the macro is referenced.
  • The Finer Points of Macros – Macros come in many forms.
  • Transclusions – Transclusions are like variables, but their value is stored in a field of a tiddler.
  • Templates and the Current Tiddler – Combining transclusions and manipulation of TiddlyWiki's currentTiddler variable gives us templates, tiddlers that control the way other tiddlers are displayed.
  • Filters and Transclusions – TiddlyWiki can transclude the output of a filter, or transclude a variable or field into a filter.
  • Text Substitution – Macros process parameters in a peculiar way, by substitution of their text, which is quite useful but also causes more confusion than almost anything else in TiddlyWiki.
  • Using Variables in Macros – Macros can reference variables as well as parameters via text substitution.
  • Wikification – TiddlyWiki converts wikitext into HTML for display by wikifying it. This process may sometimes need to be triggered manually.
  • Block Mode and Inline Mode – TiddlyWiki reads wikitext in two modes, one where elements stack horizontally and one where they stack vertically, and you occasionally have to consider which mode you should use.
  • Templates vs. Macros – Templates and macros share a surprising number of properties; a few guidelines may help you decide when to use one over the other.
  • Summary of Macro and Transclusion Syntax – Review all the syntax used for reusing and relating content in TiddlyWiki.
5: More Organizational Tools
In which we cover miscellaneous TiddlyWiki features that didn't fit in any of the previous chapters, including images, tabs, and more on filters and tags.
  • Classifying Tags – The colors and icons of tags can be customized to make it easier to tell tags with different functions apart.
  • Multi-Run Filters – Filters can be made more complex and powerful by including more than one run.
  • Images and Attachments – Content other than wikitext can be embedded into a TiddlyWiki, or stored outside of it and referenced in a variety of ways.
  • Tabs – The tabs macro facilitates compact display of a number of related tiddlers, as in the sidebar of a stock TiddlyWiki.
  • Data Tiddlers – A data tiddler packs a series of name-value pairs into a single tiddler's text field.
6: Looking Under the Hood
In which we follow the implications of everything being a tiddler to their conclusions: TiddlyWiki can be extensively customized with little more than the tools we've already learned.
  • System Tiddlers – Almost everything in TiddlyWiki is controlled by tiddlers; system tiddlers are those hidden “meta-tiddlers” that control the wiki rather than containing your actual content.
  • Plugins – Plugins are bundles of tiddlers that provide new functionality.
  • Shadow Tiddlers – Shadow tiddlers are tiddlers that are provided by plugins; they can be overridden if you want to customize a plugin.
  • Global Macros – Macros can be made available to all tiddlers in the wiki, or to some subset of tiddlers.
  • The View Template – The ViewTemplate is a special template TiddlyWiki uses internally to render each story in the story river; you can customize it to add custom content to all tiddlers or a subset of tiddlers.
  • Adding to the Sidebar – Arbitrary tiddlers can be added to the sidebar to expose custom navigation options or any other content you like.
  • Stamps – Stamps allow quick insertion of commonly-used snippets of text into tiddlers while editing.
  • Creating a List of Links and Backlinks – Dive into adding custom tooling to TiddlyWiki by building a list of outbound and inbound links that appears at the bottom of every tiddler.
  • Buttons and Input Widgets – Buttons and input widgets allow you to create custom user interfaces that edit fields and take actions in the wiki.
  • Creating Tiddlers With Predefined Fields – Explore buttons, system tags, action widgets, and messages by adding new buttons to the toolbar that create tiddlers with some custom field values already in place.
7: Tips and Tricks
In which we explore some widgets, tips, tricks, and hacks that will serve you well on the rest of your TiddlyWiki journey.
  • Getting the Current Tiddler Right on Drafts – The side-by-side preview won't display correctly when the current tiddler is used in certain ways, but you can work around it.
  • Hiding and Showing Things – Portions of tiddlers can be hidden and shown selectively using the $list widget and the $reveal widget.
  • Miscellaneous Widgets – A handful of widgets are frequently useful but haven't been needed in this book thus far.
  • Working with Dates – TiddlyWiki offers tooling for displaying, retrieving, and computing differences between dates.
  • Qualification – The qualify macro lets you avoid having state in one use of a template affect another use of a template.
8: Getting Technical
In which software developers and other computer geeks can learn how to extend and interact with TiddlyWiki using JavaScript, CSS, and external programs.
  • JavaScript Macros – Macros can execute JavaScript code rather than evaluating wikitext.
  • Stylesheets – Every little bit of page formatting can be customized by adding CSS to your wiki.
  • Creating Plugins – You can share your custom TiddlyWiki tools with other wikis and users by extracting them into plugins.
  • Writing Shell Scripts Against a TiddlyWiki – External tools can access the data in your TiddlyWiki by reading files and calling a Node.js CLI.
