There are 4 | just a few small guidelines you need to follow. 5 | 6 | ## Contributor License Agreement 7 | 8 | Contributions to this project must be accompanied by a Contributor License 9 | Agreement. You (or your employer) retain the copyright to your contribution; 10 | this simply gives us permission to use and redistribute your contributions as 11 | part of the project. Head over to to see 12 | your current agreements on file or to sign a new one. 13 | 14 | You generally only need to submit a CLA once, so if you've already submitted one 15 | (even if it was for a different project), you probably don't need to do it 16 | again. 17 | 18 | ## Code Reviews 19 | 20 | All submissions, including submissions by project members, require review. We 21 | use GitHub pull requests for this purpose. Consult 22 | [GitHub Help](https://help.github.com/articles/about-pull-requests/) for more 23 | information on using pull requests. 24 | 25 | ## Community Guidelines 26 | 27 | This project follows [Google's Open Source Community 28 | Guidelines](https://opensource.google/conduct/). 29 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # typograms 2 | 3 | Typograms (short for typographic diagrams) is a lightweight image format 4 | (`text/typogram`) useful for defining simple diagrams in technical 5 | documentation. 6 | 7 | See it in action here: 8 | 9 | https://google.github.io/typograms/ 10 | 11 | Like markdown, typograms is heavily inspired by pre-existing conventions 12 | found in ASCII diagrams. A small set of primitives and rules to connect 13 | them is defined, which you can use to build larger diagrams. 14 | 15 | Typograms optimizes for editability and portability (e.g. plain text is 16 | easy to maintain, change, store and transmit), at the cost of expressivity 17 | (e.g. SVG is more expressive) and ergonomics (e.g. higher level tools 18 | produce diagrams faster). 19 | 20 | You can embed typograms into pages using the polyfill library: 21 | 22 | ```html 23 | 24 | 25 | 30 | 31 | ``` 32 | 33 | A comparison with related work is available below. 34 | 35 | A polyfill is available that allows you use to use it in browsers. 36 | 37 | 38 | -------------------------------------------------------------------------------- /test.html: -------------------------------------------------------------------------------- 1 | 2 | 3 |

Overview

123 | 124 |

Typograms (typographic diagrams) is a lightweight image format (text/typogram) useful for defining simple diagrams in technical documentation.

125 | 126 |

Like markdown, typograms is heavily inspired by pre-existing conventions found in ASCII diagrams. A small set of primitives and rules to connect them is defined, which you can use to build larger diagrams.

127 | 128 |

Typograms optimizes for editability and portability (e.g. plain text is easy to maintain, change, store and transmit), at the cost of expressivity (e.g. SVG is more expressive) and ergonomics (e.g. higher level tools produce diagrams faster).

129 | 130 |

131 | 132 |

A polyfill is available that allows you use to use it in browsers.

Installation

135 | 136 | To get started, the easiest way to use typograms is to link from our CDN: 137 | 138 | 
139 |       
140 | <body>
141 |   <script src="https://google.github.io/typograms/typograms.js"></script>
142 |   <script type="text/typogram">
143 | +----+
144 | |    |---> My first diagram!
145 | +----+
146 |   </script>
147 | </body>
148 |       
149 |
150 | 151 | From there, you can download the library directly to serve yourself. 152 | 153 | You can also use it as a command line tool or a node library: 154 | 155 | https://github.com/google/typograms 156 | 157 |

Primitives

158 | 159 |

Typograms are composed of primitives and connectors that combine them: pipes (| - _ \ / : ~), dots arrows (> ^ * o # v < ) and Connectors (+ . -).

160 | 161 |

By putting them together, you can form a lot of different diagrams.

The closest work to typograms is svgbob: it renders diagrams from ASCII and works in browsers (through a webassembly port which spits out SVGs). It supports a similar set of features (with the notable exception of its support for circle drawing) and picks a similar set of typographic conventions (with the notable exception of text rendering). It is well-specified. I ran into enough challenges with (a) the text rendering and (b) running in the browser through the webassembly port that motivated me to rewrite it in JS (svgbob is written in rust), but is otherwise a perfectly valid (more mature) alternative.

732 | 733 |

From there, there is a series of projects that rendered images from ASCII diagrams but weren't either (a) particularly good to be used in isolation (i.e. just diagrams) or (b) on webpages (i.e. running natively in browsers): asciitosvg, ditaa and markdeep (and the go port GoAT) most notably.

734 | 735 |

Unlike libraries like mermaid, typograms are defined typographically (WYSWYG), rather than semantically (a transformation from a high level description to graphics), which picks a different trade-off: it gives you more control over the rendering (expressivity) at the cost of making you type more (productivity).
