jabs-mimir 0.5.0

A reusable tkinter/ttkbootstrap UI framework

Jabs Mimir

Jabs Mimir is a lightweight, extensible UI micro-framework built on top of tkinter and ttkbootstrap, designed for rapid internal tool development and structured form workflows.

It provides:

• Reusable UI primitives with validation and tooltips
• Support for block-based form components with dynamic variable binding
• Integration with custom validation logic (via resolver, file loader, or direct function)
• Modular architecture suitable for internal tooling and small boilerplate projects

---

Installation

pip install jabs-mimir

Quick Start

from jabs_mimir import Mimir, DataBlockWrapper, UtilityModule
import tkinter as tk
import ttkbootstrap as tb

class App(tb.Window):
    def __init__(self):
        super().__init__(title="Mimir Demo")
        self.ui = Mimir(self)

        # Option 1: Inline validator resolver (string-based)
        self.ui.setValidatorResolver(lambda name: {
            "not_empty": lambda val: bool(str(val).strip())
        }.get(name))

        # Option 2 (alternative): load from file
        # self.ui.setValidatorFile("include/validator.py")

        self.ui.switchView(self.mainView)

    def mainView(self, ui, *args):
        frame = tb.Frame(self)
        fields = [
            {"type": "heading", "label": "Basic Info"},
            {"label": "Name", "key": "name", "variable": tk.StringVar(), "validation": "not_empty"},
            {"label": "Age", "key": "age", "variable": tk.IntVar()}
        ]

        meta = UtilityModule.buildBlockMeta(fields)
        block = DataBlockWrapper(meta)

        ui.renderFields(frame, fields)
        ui.addNextButton(frame, row=len(fields)+1, command=lambda: print(UtilityModule.getBlockValues(block)))

        return frame

if __name__ == "__main__":
    app = App()
    app.mainloop()

Validation

Jabs Mimir supports both automatic and manual validation, triggered on field focus-out and verified again when clicking "Nästa".

You can define validation in two ways:

1. String-based validation (via file or resolver)

Define a validator in a file:

# include/validator.py
def not_empty(value):
    return bool(str(value).strip())

Load it:

self.ui.setValidatorFile("include/validator.py")

Use string key in field:

{"label": "Name", "variable": tk.StringVar(), "validation": "not_empty"}

2. Direct function reference

from include.validator import not_empty

fields = [
    {"label": "Name", "variable": tk.StringVar(), "validation": not_empty}
]

✅ Both methods are fully supported and interchangeable.

Mimir automatically:

• Binds validation on focus-out
• Stores all validators internally
• Re-validates all fields when clicking "Nästa"
• Blocks navigation if any invalid inputs remain
• Highlights invalid fields with red styling

Works even for readonly fields (like file upload paths), which normally can't be focused.

Components

Mimir

Manages UI views, tooltips, validation, field rendering, and form logic. Supports reusable custom field types via registerFieldType().

DataBlockWrapper

A wrapper for block-level form metadata and values. Supports dot-access and .get()/.set() calls.

UtilityModule

Helper methods for building field metadata, extracting values, validating blocks, and block meta handling.
