Installation
Requires Ruby 1.9.3+, WOFF2, FontForge with Python scripting.
# On Mac
brew tap bramstein/webfonttools
brew update
brew install woff2
brew install fontforge --with-python
brew install eot-utils
gem install fontcustom
# On Linux
sudo apt-get install zlib1g-dev fontforge
git clone https://github.com/bramstein/sfnt2woff-zopfli.git sfnt2woff-zopfli && cd sfnt2woff-zopfli && make && mv sfnt2woff-zopfli /usr/local/bin/sfnt2woff
git clone --recursive https://github.com/google/woff2.git && cd woff2 && make clean all && sudo mv woff2_compress /usr/local/bin/ && sudo mv woff2_decompress /usr/local/bin/
gem install fontcustom
####Note for windows:
- Install fontforge: http://fontforge.github.io/en-US/downloads/windows/
- Install to a path without spaces, eg c:\FontForgeBuilds
- At the end of the installer check the 'run fontforge' box. It finishes some set up.
- Add the installation path to your System PATH variable (c:\FontForgeBuilds\bin)
- Open up a new command prompt and test it.
fontforge -help
- gem install fontcustom
Quick Start
fontcustom compile my/vectors # Compiles icons into `fontcustom/`
fontcustom watch my/vectors # Compiles when vectors are changed/added/removed
fontcustom compile # Uses options from `./fontcustom.yml` or `config/fontcustom.yml`
fontcustom config # Generate a blank a config file
fontcustom help # See all options
Configuration
To manage settings between compiles, run fontcustom config
to generate a
config file. Inside, you'll find a list of all possible options.
Each option is also available as a dash-case command line flag (e.g.
--css-selector
) that overrides the config file.
SVG Guidelines
- All colors will be rendered identically. Watch out for white fills!
- Use only solid colors. SVGs with transparency will be skipped.
- For greater precision in curved icons, use fills instead strokes and try these solutions.
- Activating
autowidth
trims horizontal white space from each glyph. This can be much easier than centering dozens of SVGs by hand.
Advanced
For use with Compass and/or Rails
Set templates
to include scss-rails
to generate a SCSS partial with the
compatible font-url() helper. You'll most likely also need to set
preprocessor_path
as the relative path from your compiled CSS to your output
directory.
Example Use in Rails
Add gem 'fontcustom'
to your gem file.
bundle
Create a fontcustom.yml
file with something like this:
# config/fontcustom.yml
font_name: icons
css_selector: .icon-{{glyph}}
preprocessor_path: ""
autowidth: false
no_hash: true
force: false
debug: false
quiet: false
input:
vectors: app/assets/icons
output:
fonts: app/assets/fonts
css: app/assets/stylesheets
templates:
- scss
This tells the gem to take the vectors from app/assets/icons
and create fonts and stylesheets for them.
Create a file in lib/tasks called icons.rake
:
namespace :icons do
task :compile do
puts "Compiling icons..."
puts %x(fontcustom compile)
end
end
Load up the icons directory and test it out.
Run this command with
rake icons:compile
This should run the installed and configured gem to create your icons:
Compiling icons...
create .fontcustom-manifest.json
create app/assets/fonts
create app/assets/fonts/icons.ttf
app/assets/fonts/icons.svg
app/assets/fonts/icons.woff
app/assets/fonts/icons.eot
create app/assets/stylesheets/_icons.scss
Access these new icons by creating a tag with the class icon-{{glyph}}
where the {{glyph}} is the name of the svg you put in the icon folder.
For example, if you added a file called 'cars54' icon would look something like this:
<i class="icon-cars54"</i>
Now the font is adjustable to css 'font-size' and 'color'.
Save CSS and fonts to different locations
You can save generated fonts, CSS, and other files to different locations by
using fontcustom.yml
. Font Custom can also read input vectors and templates
from different places.
Just edit the input
and output
YAML hashes and their corresponding keys.
Tweak font settings
By default, Font Custom assumes a square viewBox, 512 by 512, and 16 pica
points. Change font_design_size
, font_em
, font_ascent
, font_descent
,
and autowidth
to suit your own needs.
Generate LESS, Stylus, and other text files
Custom templates give you the flexibility to generate just about anything you want with Font Custom's output data.
Any non-SVG file in your input directory (or input:templates directory if you
set it in fontcustom.yml
) will be available as a custom template to copy into
the output directory after compilation. You just need to specify the file name
under the templates
hash.
Any embedded ruby in the templates will be processed, along with the following helpers:
font_name
font_face
: FontSpring's Bulletproof @Font-Face Syntaxglyph_selectors
: comma-separated list of all icon CSS selectorsglyphs
: all selectors and their codepoint assignments (.icon-example:before { content: "\f103"; }
)@options
: a hash of options used during compilation@manifest
: a hash of options, generated file paths, code points, and just about everything else Font Custom knows.@font_path
: the path from CSS to font files (without an extension)@font_path_alt
: ifpreprocessor_path
was set, this is the modified pathpseudo_element
: ifcss3
was set to true, then it will print::before
. Otherwise the PseudoElement will be:before
font_face
accepts a hash that modifies the CSS url() function and the path of
the font files (font_face(url: "font-url", path: @font_path_alt)
).
