Sol ☀️
[!WARNING] Sol is current in early development and is not available for usage yet.
Sol is a data/markup/scripting language for applications and assets. Being text-based, you can check .sol
into version control, and being backend-agnostic means you can port assets across engines and implementations.
Sol itself is highly portable -- it's written in Rust and only requires providing implementations for external symbols you define.
Features
Sol comes with many language features, from contract definitions to full-on programming.
Models
You can define type safe models...
model Item
field name : text
field usage_count : text
field consume_when_used : truth
field on_use : Action
end
...and them implement them on another file.
impl Item
name = "Hamburger"
usage_count = 1
consume_when_used = yes
action on_use
* You eat the {name}.
* It tastes like cardboard.
player.stats.heal(HP, 10)
* Restored 10HP!
end
Dialogs
Notably, Sol has builtin support for dialogues, making for a beautiful cutscene format, that looks like a screen play.
use game::chapter_1::RETURNED_TO_SCHOOL
scene "School Entrance"
with player do
.move(10, 20)
.look_at(Alexander)
end
[Alexander smiling]
- Welcome back, dude? How have you been?
wait(2.0 seconds)
[& guilty]
- Not much for talking, huh...
- Um... by the way... eh...
- Sorry for back there... when I... um... abandoned you...
[& smiling]
- No hard feelings, right?
[Player]
- *sigh*...
set RETURNED_TO_SCHOOL
end
Facts
Sol allows defining typed algebraic facts that help you ensure your game is in a valid state.
let chapter1 : some {
SCHOOL_BEGGINING,
DUNGEON_1 : some {
PART_1,
PART_2,
PART_3 : all {
BOSS_STATUS: either {
BEFORE_BOSS,
AFTER_BOSS : all {
death_count : i32,
used_violence : truth,
}
},
SECRET_PUZZLE_STATUS: {
UNDISCOVERED,
UNFINISHED,
COMPLETED_N_TIMES : i32
},
},
},
RETURNED_TO_SCHOOL,
}
A fact is a model, and a save file is an implementation of a fact model. By using Sol, saving and loading is effortless and fast.
