About
Declarative TUI (Terminal User Interface) library, with layout features modelled after modern web components.
Widget objects can be created by defining a class that inherits from the desired widget class.
For example, a CSS flexbox-style widget that contains a text box and a button can be created declaratively, like so:
class NiceFlexBox(widgets.FlexBox):
text_box = widgets.TextBox(text="Hello World!")
button = widgets.Button(label="Button 2", callback=None)

class Meta:
border_label = "Nice FlexBox"

nice_flex_box = NiceFlexBox()

or imperatively, like so:
children = {
'text_box': widgets.TextBox(text="Hello World!"),
'button': widgets.Button(label="Button 2", callback=None)
}

nice_flex_box = widgets.FlexBox(children=children, border_label="Nice FlexBox")

Tanmatsu supports either style. The declarative syntax should be familiar with anyone who's used Django models before.
Example

which is given by the code:
from tanmatsu import Tanmatsu, widgets

class ButtonList(widgets.List):
class Meta:
border_label = "List"
children = [
widgets.Button(label="Button 1", callback=None),
widgets.Button(label="Button 2", callback=None),
widgets.Button(label="Button 3", callback=None),
]
item_height = 5

class VertSplit(widgets.FlexBox):
text_box = widgets.TextBox(border_label="Text Box", text="Hello World!")
text_log = widgets.TextLog(border_label="Text Log")
button_list = ButtonList()

class Meta:
flex_direction = widgets.FlexBox.HORIZONTAL


with Tanmatsu(title="Tanmatsu!") as t:
rw = VertSplit()
t.set_root_widget(rw)

for (i, v) in enumerate(rw.button_list.children):
v.callback = lambda i=i: rw.text_log.append_line(f"Button {i + 1} pressed")

t.loop()
