# Relm4 icons - Icons for your gtk-rs and Relm4 applications!

More than 3000 icons, ready for use in your app!
## Installing librsvg
The `relm4-icons` crate relies on `librsvg` for rendering SVG icons. Ensure that `librsvg` is installed on your system before using this crate. The installation process varies depending on your operating system.
```bash
# Linux (Debian/Ubuntu)
sudo apt update
sudo apt install librsvg2-dev
# Macos
brew install librsvg
# Windows
gvsbuild build librsvg
```
## Usage
### 1. Find your icons 🔍
You can either use the of the over 3000 shipped icons or your own icons.
You can browse the shipped icons using one of the following methods:
For icons from the GNOME [icon-development-kit](https://gitlab.gnome.org/Teams/Design/icon-development-kit):
+ Install [Icon library](https://flathub.org/apps/details/org.gnome.design.IconLibrary)
+ Browse the [GNOME icon resource](https://teams.pages.gitlab.gnome.org/Design/icon-development-kit-www/)
For icons from [Fluent UI System Icons](https://github.com/microsoft/fluentui-system-icons):
+ Browse the [fluent icon library catalog](https://aka.ms/fluentui-system-icons)
For browsing all shipped icons:
+ Use the icon previews provided by in this repo: [16x16](icons16.md), [32x32](icons32.md) and [64x64](icons64.md)
> Sometimes, icons-development-kit and Fluent UI System Icons have overlapping icon names, so the postfix "-alt" is added.
### 2. Add Relm4 icons ✍
```toml
relm4-icons = "0.10.0-beta.1"
[build-dependencies]
relm4-icons-build = "0.10.0-beta.1"
```
### 3. Add the icons to your project 📦
Add the following to your `build.rs`:
```rust
fn main() {
relm4_icons_build::bundle_icons(
// Name of the file that will be generated at `OUT_DIR`
"icon_names.rs",
// Optional app ID
Some("com.example.myapp"),
// Custom base resource path:
// * defaults to `/com/example/myapp` in this case if not specified explicitly
// * or `/org/relm4` if app ID was not specified either
None::<&str>,
// Directory with custom icons (if any)
None::<&str>,
// List of icons to include
[
"ssd",
"size-horizontally",
"cross",
],
);
}
```
### 4. Load the icons 🛫
Add this to your initialization code:
```rust
mod icon_names {
include!(concat!(env!("OUT_DIR"), "/icon_names.rs"));
}
fn main() {
///...///
relm4_icons::initialize_icons(icon_names::GRESOURCE_BYTES, icon_names::RESOURCE_PREFIX);
}
```
### 5. Use the icons 🎉
Use `set_icon_name` and similar methods to use your icons, for example with
[`ButtonExt`](https://gtk-rs.org/gtk4-rs/git/docs/gtk4/prelude/trait.ButtonExt.html#tymethod.set_icon_name),
[`StackPage`](https://gtk-rs.org/gtk4-rs/git/docs/gtk4/struct.StackPage.html#method.set_icon_name),
[`MenuButton`](https://gtk-rs.org/gtk4-rs/git/docs/gtk4/struct.MenuButton.html#method.set_icon_name) or
[`Image`](https://gtk-rs.org/gtk4-rs/git/docs/gtk4/struct.Image.html#method.set_icon_name).
#### Example
```rust
let button = gtk::Button::default();
button.set_icon_name("plus");
```
You can also use the `icon_names` module for extra compile-time generated icon names.
```rust
use crate::icon_names;
let button = gtk::Button::default();
button.set_icon_name(icon_names::PLUS);
```
## How it works
### Crate
1. Collect all icons specified in the config file
2. Build a gresource bundle containing *only the selected icons*
3. Include the gresource file in the compiled binary
4. On initialization load the gresource file
### Add new icons
To add new icons, move them into the `icons` folder and make sure their file name ends with `-symbolic.svg`.
Then run the following commands:
```sh
cd update_icons
cargo run
```
Existing icon sets can be updated as submodules with following commands:
```sh
git submodule update --remote --checkout
rm -rf build_icons/icons/fluentui-system-icons
rm -rf build_icons/icons/icon-development-kit
cd update_icons
cargo run --bin fetch_icons
cargo run
```
