# Apps
Library and CLI tool for querying and launching
applications that have a corresponding `.desktop` file.
## Installation
1. install dependencies
:::code-group
```sh [<i class="devicon-archlinux-plain"></i> Arch]
sudo pacman -Syu meson vala json-glib gobject-introspection
```
```sh [<i class="devicon-fedora-plain"></i> Fedora]
sudo dnf install meson gcc valac json-glib-devel gobject-introspection-devel
```
```sh [<i class="devicon-ubuntu-plain"></i> Ubuntu]
sudo apt install meson valac libjson-glib-dev gobject-introspection
```
:::
2. clone repo
```sh
git clone https://github.com/aylur/astal.git
cd astal/lib/apps
```
3. install
```sh
meson setup build
meson install -C build
```
:::tip
Most distros recommend manual installs in `/usr/local`,
which is what `meson` defaults to. If you want to install to `/usr`
instead which most package managers do, set the `prefix` option:
```sh
meson setup --prefix /usr build
```
:::
## Usage
You can browse the [Apps reference](https://aylur.github.io/libastal/apps).
### CLI
```sh
astal-apps --help
```
### Library
:::code-group
```js [<i class="devicon-javascript-plain"></i> JavaScript]
import Apps from "gi://AstalApps"
const apps = new Apps.Apps({
includeEntry: true,
includeExecutable: true,
})
for (const app of apps.fuzzy_query("spotify")) {
print(app.name)
}
```
```py [<i class="devicon-python-plain"></i> Python]
from gi.repository import AstalApps as Apps
apps = Apps.Apps(
include_entry=True,
include_executable=True,
)
for app in apps.fuzzy_query("obsidian"):
print(app.get_name())
```
```lua [<i class="devicon-lua-plain"></i> Lua]
local Apps = require("lgi").require("AstalApps")
local apps = Apps.Apps({
include_entry = true,
include_executable = true,
})
for _, app in ipairs(apps:fuzzy_query("lutris")) do
print(app.name)
end
```
```vala [<i class="devicon-vala-plain"></i> Vala]
// Not yet documented, contributions are appreciated
```
:::
:::info
The fuzzy query uses [Levenshtein distance](https://en.wikipedia.org/wiki/Levenshtein_distance). I am not a mathematician, but if you know how to reimplement
the logic of [fzf](https://github.com/junegunn/fzf) to make it better feel free to open PRs.
