go-findfont

A platform-agnostic go (golang) library to easily locate truetype font files in your system's user and system font directories.

What?

go-findfont is a golang library that allows you to locate font file on your system. The library is currently aware of the default font directories on Linux/Unix, Windows, and MacOS.

How?

Installation

Installing go-findfont is as easy as

go get -u github.com/flopp/go-findfont

Library Usage

import (
  "fmt"
  "io/ioutil"
  
  "github.com/flopp/go-findfont"
  "github.com/golang/freetype/truetype"
)

func main() {
  fontPath, err := findfont.Find("arial.ttf")
  if err != nil {
    panic(err)
  }
  fmt.Printf("Found 'arial.ttf' in '%s'\n", fontPath)

  // load the font with the freetype library
  fontData, err := ioutil.ReadFile(fontPath)
  if err != nil {
    panic(err)
  }
  font, err := truetype.Parse(fontData)
  if err != nil {
    panic(err)
  }

  // use the font...
}

go-findfont's Issues

I think I can get the font name supported by the system?

Use `fc-match` on Linux

I think this library should use the fc-match command on Linux to find fonts. See e.g. https://unix.stackexchange.com/questions/123511/find-font-file-from-font-name-on-linux

Feature request - add .otf

Since the golang.org/x/image/font/sfnt package reads TTF and OTF, can you add .otf to the list of allowed suffixes in findfont.go:50?

Thanks.

Unable to find TTC font

I use windows 10 operating system, some of which are in TTC format, but use findfont.List() function can only find the font format of TTF

Proposal: tag version 0.1.0 ?

Hi,

firstly, thank your for investing your time in a general purpose library !

As your lib seems to be quite stable over the last couple of month, would you mind tagging it with a zero version; something like v0.1.0? A zero version would not mean any commitment to API-stability from your side, as zero versions are supposed to be unstable.

However, it would help clients lock their dependencies in case you'll extend your lib to include fc-match or other feature-/API-changes.

Cheers,
--Norbert

go get fails on Windows and Mac

The platform specific files do not support "unix" as an option, so condition build tags need to be added to fontdirs-unix.go

I have included a pull request #3

Support symlinks in paths

To look for fonts, findfond uses filepath.Walk(). The documentation for filepath.Walk() says:

Walk does not follow symbolic links.

This is a problem if fonts can be found only by symlinks. This is the case on Nix, at least.

There is a package, symwalk that works like filepath.Walk, but does follow symlinks. It should be possible to use that instead.
