Emacs SVG libraries for creatings tags, icons and bars

SVG Library

svg-lib is an Emacs library that allows to create and display various SVG objects, namely tags, icons, buttons, progress bars, progress pies and dates. Each object is guaranteed to fit nicely in a text buffer ensuring width is a multiple of character width and height a multiple of character height.

Installation

M-x package-install RET svg-lib RET

Quick start

For the impatient, evaluate the following expression:

M-: (insert-image (svg-lib-tag "TODO"))

This should insert a SVG tag displaying “TODO” in a rounded box whose size is exactly 5 characters wide (because of padding).

Usage

Objects

• svg-lib-tag LABEL
• svg-lib-icon ICON
• svg-lib-icon+tag ICON LABEL
• svg-lib-button LABEL HOOK
• svg-lib-progress-bar VALUE
• svg-lib-progress-pie VALUE
• svg-lib-date DATE

Styling

Each library object can be styled using a style property list that defines:

• foreground color
• background color
• internal padding (tag and icon)
• external margin (in char)
• stroke width (in pixels)
• corner radius (in pixels) for the rounded box
• horizontal alignment (0 to 1) inside margins
• width (in characters)
• height as a scale of line height
• scale (for icon)
• ascent (for text)
• crop-left to crop object on the left
• crop-right to crop object on the right
• collection to use for icon
• font family
• font size
• font weight

Icon repositories

Icons can be created by parsing remote collections whose license are compatibles with GNU Emacs. The default size of an icon is exactly 2x1 characters such that it can be inserted inside a text without disturbing alignment.

Each icon is cached locally to speed-up loading the next time you use it. If for some reason the cache is corrupted you can force reload using the svg-icon-get-data function. If you want to add new collections (i.e. URL), make sure the icons are monochrome, that their size is consistent and that they include a ‘viewBox’ node.
