rust-font-loader's Issues

Android integration

The font loading and parsing logic is implemented in java. They parse a simple xml file which contains all the infos, so replicating shouldn't be a problem.

Parsing by third party apps is NOT supported, see source, which means we'll have to specialize for android releases, in case they change behaviour. Also unchecked, which Android version is the earliest we could supported with this?

(Optionally) work with fontconfig-sys instead of servo-fontconfig-sys

I'm trying to use font-loader with glium_text, which uses fontconfig-sys. If I try to use them both at once, it gives me error: native library `freetype` is being linked to by more than one package, and can only be linked to by one package. Would it be feasible to make it at least optionally work with fontconfig-sys?

Improve error handling

There are a lot of unwrap()s in the code. Proper error handling with Result's would be nice.

Happy to provide guidance! Just comment on this issue.

Edit:

Windows
Fontconfig (*nix)
Mac

FontPropertyBuilder should derive std::clone::Clone

If you want to select a number of fonts of the same family this lets you write:

let regularFont = system_fonts::FontPropertyBuilder::new().family("Noto Sans");
let italicFont = regularFont.clone().italic();

rather than:

let regularFont = system_fonts::FontPropertyBuilder::new().family("Noto Sans");
let italicFont = system_fonts::FontPropertyBuilder::new().family("Noto Sans").italic();

Cannot load generic font family on MacOS

Hi,

Thanks for the great crate, I used this to load system fonts for my crate Plotters. Recently we've added a feature that supports generic font families like serif, serif-sans and monospace.

On Linux, query a generic font family will return expected result. But On MacOS, it seems font-loader doesn't have a way to load generic font family and querying "serif" will directly return FontNotFound.

I believe CTFontStylisticClass should be one way to query the generic font class.

Also there's a behavior difference on MacOS and Linux when font is not found. On Linux it returns the default font, on MacOS it returns an error.

Could you please give some guidance on this stuff ?

Thanks!

Update, just tried windows it seems it constantly return arial font if the requested font is not exists. Including requesting the general font families

Get fonts as const function

Is there a possibility to have the get function return the raw font as a const?

For crates like u8g2-fonts used for embedded-graphics you define a newly rendered font as a const DATA: &'static [u8].

DirectWrite integration

@vvuk wrote Rust bindings for DirectWrite which some applications use internally, e.g. WR/Servo.
Currently, we're using wingdi for font enumeration, but DirectWrite has an interoperabillity interface for wingdi, but this part isn't ported yet.

ToDo:

Enhance the gdi interop implementation in DirectWrite
Adapt interface

iOS integration

I don't own apple hardware, so i'd be glad if someone could provide guidance for community members on this issue!

Fallback features

Here are a few features that are higher level than what this library currently provides, but that I think would be useful for most users of this library and make sense to include:

Add a method (query_closest_available?) that given a font name or parameters will return the requested font name or fallback to a basic, available font if the requested font is not available.
Adapt the above method to return the most similar available font for the given parameters. Servo does this by defining a distance function between font descriptors, here.
Include a feature flag that if turned on will bundle a basic fallback font in your application binary, that the method in 1 and 2 will fallback to in the case that no system font is available. This flag could be enabled by default for any platforms that are otherwise unsupported to allow at least basic font loading on any platform that rust supports.
Allow applications to specify their own custom fonts that can be bundled, queried and loaded, not sure how this would work at the moment.

Of these I think 1 and 3 are the most important, whereas 2 and 4 are more "nice to have" and could be added later.

switch from `servo-fontconfig` to `fontconfig`

servo-fontconfig had its latest release over 2 years ago. It's no longer needed by servo itself and prob wont receive any updates soon. It depends on old crates like freetype-sys 0.13 .
I think we should phase servo-fontconfig out in favor for other crates.

Expose font information

Get information about the font when loading it, such as name, file path, etc. All the information provided by fontconfig or its macos/windows counterparts should be there. If you like, I can write a PR for Fontconfig's part of this, but I don't use windows or macos so I can't help you there.

Native implementation on Apple Devices (Core Graphics/Core Text)

Implement the API on Apple Device using the native APIs.

I don't own a mac and simply can't do it on my own. PRs welcome!

Use servo/fontconfig instead of silverknife bindings

As discussed here](abonander/fontconfig-rs#5 (comment)).
