## Build



### Requirements



Make sure your system support:



* Glib 2.56+

* GTK 4.10+

* Libadwaita 1.6+



Use [rustup](https://rustup.rs) installer to setup latest Rust compiler and Cargo package manager:



``` bash

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

```



#### Debian



_todo_



#### Fedora



``` bash

sudo dnf install git gcc\

                 cairo-devel glib2-devel gtk4-devel libadwaita-devel pango-devel\

                 sqlite-devel

```



### Install



#### Stable



``` bash

cargo install Yoda

```



#### Repository



``` bash

git clone https://github.com/YGGverse/Yoda.git

cd Yoda

cargo build

```



## Development



Quick start guide and maintenance protocol



### `browser`



#### Filesystem



* Use [modern path pattern](https://doc.rust-lang.org/edition-guide/rust-2018/path-changes.html#no-more-modrs)

* One module implements one GTK widget, it may include additional helper files in same location (like template, CSS or DB API)

* For children widget - create children module, located according to hierarchy



#### Codebase



* Every module should be as minimal as possible, separate:

  * different tasks

  * massive structures

  * structures with implementation

* Every module must:

  * encapsulate members - use objects, not static names (unlike native GTK actions API)

  * implement only one public API `struct` per file (same as one file for one class)

    * implementable `struct` is public, where it members - private

  * contain main `struct` implementation:

    * at least one constructor that must:

      * have common for application names: `from`, `new` or/and `new_rc`, `new_mutex`, etc - on return object in container

      * grant ownership for new `Self` object created

    * public `activate` action if the new object can not be activated on construct

    * public `link` getter for GTK `widget` (parental composition)

* Public API oriented to simple (`integer`, `boolean`), standard (`std::*`) or system-wide (`gio`, `glib`, etc) data types usage to reduce internal dependencies from app implementation



#### Database



* [SQLite](https://sqlite.org) used to operate with user profile: for example, restore and save widget sessions, manage auth, history, bookmarks, etc

* Database stored in system config directory (could be detected simply using browser tools menu)

* Structure of table should not be modified on `CARGO_PKG_VERSION_PATCH` change

* Every `browser` mod may have own table, where table must:

  * contain same name as mod location, for example `app_browser_widget` for `src/app/browser/widget.rs`

  * every table include autoincrement `id` column and parental primary ID if exist

    * column name for parental ID must have absolute namespace prefix, for example `app_browser_id` column for `app_browser_widget` table. For example, if the table has few parental keys, column set could be `id`, `parent_one_id`, `parent_two_id`, `some_data`

* _todo_

  * [ ] version control for auto-migrations

  * [x] transactions support for update operations



#### GTK



* Operate with [action objects](https://docs.gtk.org/gio/class.SimpleAction.html) instead of names like `win.action`. This allows to follow encapsulation, by the our goal, module must know nothing about parent presets. For example, define some action in parent, then delegate object created as construction argument

* Started refactory on separate widgets implementation to separated mods, because widgets may contain own tables in database and require additional mods dependencies like ORM API _todo_



### Contribution



* Before commit, please make sure:

  * new branch created for every new PR `git checkout -b 'contribution-name'`

  * new code follows common [rustfmt](https://rust-lang.github.io/rustfmt/) style `cargo fmt --check`

  * run `cargo clippy` for final optimization

### Releases



* Package version in repository should be increased immediately after stable release on [crates.io](https://crates.io/crates/yoda) and before apply new changes

* Currently, profile data stored in separated sub-directories, auto-created on every `CARGO_PKG_VERSION_MAJOR` or/and `CARGO_PKG_VERSION_MINOR` change
