And there's nothing inherently wrong with that. 59 | 60 | Nevertheless, when an application's user-facing models of thought... 61 | 1. cannot be easily mapped to the user's own mental models, or 62 | 2. are not justified for the user, 63 | 64 | it can lead to frustration. For example: 65 | - A mobile to-do list app employs a `Flagged` button that takes up valuable home screen space before any tasks have been flagged -- and without knowing whether the user intends to use the flag feature at all. (iOS 13 Reminders) 66 | 67 | - A task management app employs a model of Board -> List -> Card. Lists cannot contain other lists, cards cannot contain other cards, cards cannot contain lists, and so on. (Trello) 68 | 69 | - A to-do list app dictates a set of reserved attributes, like `Labels` and `Filters`, which cannot be removed from the interface. (Todoist) 70 | 71 | I use and love all of the above applications. Their specialization is their strength. Margin's philosophy simply asserts that there is space for a more adaptable standard for stuctured thought. 72 | 73 | In this respect, Margin promotes a common sense approach to modeling thought: simply place the thinker's preferences first. 74 | 75 | This approach begins with a flexible plain text standard. After that, it is the application's job to improve the thinker's experience through specialized tools and prescriptive user-facing models -- as long as the underlying source material remains portable and human-readable. 76 | 77 | Margin is free and open-source. 78 | 79 | ------------------------------- 80 | 81 | # Syntax 82 | 83 | Margin employs an ordered tree data structure whose nodes are called items. Indentation forms the basis of the syntax. 84 | 85 | ## Items 86 | 87 | Each line represents an item: 88 | 89 | ```margin 90 | Shirt 91 | Pants 92 | Shoes 93 | ``` 94 | Each item can have a single parent and multiple children. Indentation alone determines this hierarchy: 95 | ```margin 96 | Shirt 97 | Collar 98 | Sleeves 99 | Buttons 100 | Pants 101 | Belt loop 102 | Pockets 103 | Shoes 104 | Tongue 105 | Laces 106 | ``` 107 | Leading & trailing dashes, colons, asterisks, chevrons, underscores and whitespaces, as well as blank lines, are ignored: 108 | ```margin 109 | ** Key Takeaways ** 110 | ------------------- 111 | Feel free to use plain text decorations freely in order to: 112 | - Help structure your thinking 113 | - Make your plain text documents more easily scannable 114 | ``` 115 | [See the list of all ignored characters.](https://margin.love/ignored_characters.txt) 116 | 117 | ## Annotations 118 | 119 | An annotation is any childless item wrapped in square brackets: 120 | ```margin 121 | I'm a plain old item 122 | [and I'm an annotation] 123 | ``` 124 | Annotations can be used to store meta data: 125 | ```margin 126 | The Crying of Lot 49 127 | [author: Thomas Pynchon] 128 | [publication year: 1966] 129 | [publisher: J. B. Lippincott & Co.] 130 | ``` 131 | An annotation is the child of any inline, non-annotation item: 132 | ```margin 133 | Items: 134 | - Item A 135 | - [I belong to Item B] Item B [I also belong to Item B] 136 | - Item C 137 | [I belong to Item C] 138 | ``` 139 | Because annotations cannot have children, an indented item following an annotation is considered that annotation's parent: 140 | ```margin 141 | Items: 142 | - Item Y 143 | [I belong to Item Y] 144 | - [I belong to Item Z] 145 | Item Z 146 | ``` 147 | Escape an annotation with a backslash: 148 | ```margin 149 | This is an item \[but this is not an annotation] 150 | ``` 151 | Any text up until the (optional) first colon in an annotation may safely be interpreted as the annotation type. 152 | 153 | Annotations with type `population`: 154 | ```margin 155 | Continents 156 | Asia [population: 4,601,371,198] 157 | Africa [population: 1,308,064,195] 158 | Europe [population: 747,182,751] 159 | South America [population: 427,199,446] 160 | North America [population: 366,600,964] 161 | Oceania [population: 42,128,035] 162 | ``` 163 | Annotations with types `waiter` and `host`: 164 | ```margin 165 | Restaurant Staff 166 | Christine [waiter] 167 | Steven [waiter] 168 | Jessica [host] 169 | ``` 170 | An annotation whose type is not understood by the interpreting application may safely be ignored (but should not be discarded): 171 | ```margin 172 | [For example: this annotation won't be utilized unless the app has an interpreter for type "For example".] 173 | ``` 174 | An annotation cannot be nested: 175 | ```margin 176 | [This entire sentence [including this text] represents a single annotation] 177 | ``` 178 | 179 | ## Interpreting Items 180 | 181 | While there are no hard-and-fast rules about how items should be interpreted, the following are good guidelines for most applications. 182 | 183 | ### Tasks 184 | A task is any item that parents an annotation of type `x` or `empty string`: 185 | ```margin 186 | Daily Rituals 187 | [x] Meditate 188 | [ ] Work Out 189 | [ ] Read for 10 minutes 190 | ``` 191 | 192 | ### Links 193 | An annotation of type `http` or `https` represents a link: 194 | ```margin 195 | Some people choose to set their homepage to [http://www.google.com]. 196 | ``` 197 | Text to the left of the annotation not separated by an `empty string` is the link's label: 198 | ```margin 199 | I rarely use Yahoo[http://www.yahoo.com] for search anymore. 200 | ``` 201 | For multi-word labels, wrap the entire label in parentheses: 202 | ```margin 203 | Sometimes I do read (Yahoo News)[https://news.yahoo.com], though. 204 | ``` 205 | 206 | ### Indexes 207 | An index is any item that parents an annotation of type `filter`: 208 | ```margin 209 | Now Playing [filter: release date is before tomorrow] 210 | Coming Soon [filter: release date is after today] 211 | ``` 212 | An application may use the specified query to filter for certain nodes under certain conditions of interaction. For most applications, the default filter for a given task (when no filter is specified) would be that task's children. But this is outside the scope of the markup language itself. 213 | 214 | ### Document Parent 215 | Every Margin document has an implied document parent, an item that parents every top-level item in the document. This item can also have annotations, which can be useful as document-level meta data. These annotations are defined as the first apparently parentless annotation in the document: 216 | ```margin 217 | [Kid Reader Pro] 218 | [Reader Name: Kit Mapache] 219 | 220 | Read: 221 | - The Phantom Tollbooth 222 | - A Wrinkle in Time 223 | - Charlotte's Web 224 | 225 | Unread: 226 | - Where the Wild Things Are 227 | ``` 228 | 229 | # Try it out 230 | 231 | The Margin JavaScript parser is currently in alpha. [You can try it out for yourself here](https://margin.love/parser), but note that some functionality defined in this spec will not yet function properly. 232 | 233 | # Implementations 234 | 235 | - This repo contains the original Javascript implementation. 236 | - [MarginRB](https://github.com/burlesona/margin-rb) - Ruby implementation by @burlesona 237 | 238 | # Questions 239 | 240 | **Why not TaskPaper?** 241 | 242 | [TaskPaper](https://www.taskpaper.com) is a great, minimal app for creating to-do lists. Some readers might feel that Margin's capabilities are redundant, but I believe Margin stands apart in several key ways: 243 | 244 | - Margin is not an app, but a markup language. 245 | - Margin is hierarchically less prescriptive than TaskPaper. Where TaskPaper splits items into `projects`, `tasks`, and `notes`, Margin sees only items. A top-level item in Margin *could* be considered a project, but it could also just as easily be considered a list, a note, a task, a chapter, an employee, an index, etc. 246 | - Margin is syntactically less prescriptive than [TaskPaper's formatting](https://guide.taskpaper.com/getting-started/). TaskPaper categorizes items by their ornamentation (`projects` end with a colon, `tasks` begin with a dash, and `notes` must not fall into either of those two categories). Margin intentionally avoids such definitions, allowing the user to ornament (or not) plain text in nearly any format they prefer. 247 | 248 | **Indentation? Human-readable? Won't a complicated Margin document just end up as a jumbled mess of deeply indented text blocks and annotations?** 249 | 250 | Margin isn't meant for storing complex databases. It's meant to make text-based structured thought portable and platform-independent. In the same way that Markdown is built to translate into HTML, but you wouldn't build a web app in Markdown, so Margin too has its limitations. The idea is to de-formalize any unnecessary syntactic requirements, leaving only indentations and a select number of special operators to dictate the parsing of the language. Keeping it simple has its benefits, but it also has its costs. 251 | 252 | **What is the preferred extension for Margin files?** 253 | 254 | Margin files use the extension `.margin`. 255 | 256 | **Does Margin support multi-line items?** 257 | 258 | No. But if you're writing in Margin and you really want items to span multiple lines, feel free to use whatever syntax appeals to you to acheive that. Margin certainly doesn't care what you do in the privacy of your own plain text editor. Just don't expect those multi-line items to be interpreted properly by a given application. 259 | 260 | **Where can I send feedback?** 261 | 262 | Please submit any feedback as an issue on [Margin's public GitHub repository](https://github.com/gamburg/margin/issues). 263 | -------------------------------------------------------------------------------- /_coverpage.md: -------------------------------------------------------------------------------- 1 | 2 | 3 | > ⊙ 4 | # Margin 5 | 6 | > Lightweight markup designed for an open mind 7 | 8 | - The plain text language for list-making, note-taking, and to-dos. 9 | - Thinkers determine their own organizational models. 10 | - Infinitely extensible, inherently readable. 11 | 12 | 13 | [Learn Margin →](#philosophy) 14 | [Try it out ✎](https://margin.love/parser) 15 | [GitHub ♡](https://github.com/gamburg/margin) 16 | 17 | 18 | 19 | ![color](#f0f0f0) 20 | -------------------------------------------------------------------------------- /assets/fonts/labmono-license.txt: -------------------------------------------------------------------------------- 1 | Copyright (c) 2015, Martin Wecke (http://martinwecke.de), 2 | with Reserved Font Name Lab Mono. 3 | 4 | This Font Software is licensed under the SIL Open Font License, Version 1.1. 5 | This license is copied below, and is also available with a FAQ at: 6 | http://scripts.sil.org/OFL 7 | 8 | 9 | ----------------------------------------------------------- 10 | SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007 11 | ----------------------------------------------------------- 12 | 13 | PREAMBLE 14 | The goals of the Open Font License (OFL) are to stimulate worldwide 15 | development of collaborative font projects, to support the font creation 16 | efforts of academic and linguistic communities, and to provide a free and 17 | open framework in which fonts may be shared and improved in partnership 18 | with others. 19 | 20 | The OFL allows the licensed fonts to be used, studied, modified and 21 | redistributed freely as long as they are not sold by themselves.
