# compot
Compot is a simple, compositional framework for building TUIs. It is heavily
inspired by `jetpack-compose` and strives to be its equivalent in TUIs.
Currently, it is in its early stages of development as I do not have much time
to dedicate it and am developing it for internal use at work. As requirements
expand, so too will `compot`.
## Features
* Abstractions beyond low-level `curses`
* Fully Stateless
* Lazy Rendering
* Fully written in python
What all this means is that `curses` development becomes a breeze. Here's an
example:
```python
@Composable
def StatusBar(
content: Tuple[Tuple[ComposableT, ...],
Tuple[ComposableT, ...],
Tuple[ComposableT, ...]],
measurement: MeasurementSpec = MeasurementSpec.INJECTED()
):
return Row(
children=content,
measurement=measurement,
layout=LayoutSpec.FILL,
spacing=RowSpacing.SPACE_BETWEEN
)
```
This is the source code for the `StatusBar` widget. To invoke it, run it with:
```python
StatusBar(
(
Text('Left Status'),
Text('Center Status'),
Text('Right Status')
),
measurement=MeasurementSpec.xywh(0, 0, bar_w, 1)
).build().render()
```
Only the top level element needs to know its measurements (as of now, there is
no `MainWindow`-like widget that would handle this for you automatically), and
everything else gathers its measurements automatically
Note some of the cool things here:
* Until you call `Composable.build()` nothing actually gets invoked. Simply
calling `StatusBar` just makes a very small data structure that holds all
the data required to build the `StatusBar`, but until you call `build` its
measurements, its specs are all indeterminate. Calling `build` then forces
the UI element to actually figure out its dimensions and create all the
required objects. Usually this requires the widget to ask its child widgets
to predict how large they are going to be, but even then, only the bare
minimum is done to actually measure the widgets. `build` then constructs a
graph that is rendered with `render()`.
* Everything is automatic! Where do I position the `Left Status` text? Where
does `Center Status` go? What about `Right Status`? **We don't care.**
`StatusBar` figures it out (actually, the
`spacing=RowSpacing.SPACE_BETWEEN`) value given to `Row` in `StatusBar`
forces the desired `StatusBar` behavior.
## The downsides
* The codebase is in a state of improvement and development.
* The API is bound to change.
* The number of widgets is too small to make a usable product out of this as of
now.
## Requirements
The only requirement is that you have `python > 3.8`. I do not plan to support
lower versions of `python` and cannot help in supporting them.
## Installing
You should be able to get up and running by running
```bash
pip install compot-ui
```
## Tests
Tests are very rudimentary and you must manually test all the widgets that are
available currently. Check the `tests/ui` directory and run each of the scripts
to see how they appear.
