el-std-py

el-std-py is an assortment of useful python utilities complementing some builtin and third party python packages.

Disclaimer

1. I mainly develop this library for my own use use, and while I do think that it might be useful to others, there is no guarantee that features work as expected and I may introduce breaking changes to APIs at any time.
2. While the el-std-py is namely related to my el-std-cpp library, the two are not related in any way content-wise and there is no promise of feature parity whatsoever. Both libraries are simply utility libraries for the respective languages with features I commonly use in them. They are otherwise independent.

Versions

I am currently targeting Python 3.13 for this library. Although some things might work in earlier versions, there is no guarantee, and I will not refrain from using the latest python features.

Features and Documentation

While I might write more comprehensive documentation for some features along the way, I will at least try to maintain an up-to-date list of all available features:

(when reading from PyPi, some links might not work. View on GitHub for full documentation)

General program logic

• el.async_tools: Utility functions for working with asyncio
• el.terminal: Terminal controller enabling an asynchronous command interface and a color-coded logging configuration that is a good stating point and pushes logs to stdout without disturbing the user command line.
• el.observable: Data wrapper classes allowing the observation and chaining of value change events and thus declaratively defining data paths
• el.bindantic: An unofficial "extension" (one could call it a "mod") for pydantic that adds support for defining, dumping and validating binary data structures (like in C), while maintaining all pydantic features.
• el.callback_manager: Simple callback registry class for exposing events
• el.lifetime: Contextual lifetime management for registries (Any object that requires to register something, like a CallbackManager or Observable)
• el.datastore: Zero-setup database-like data and configuration file handler that uses pydantic do define data models and asyncio to automatically store/load them to/from disc in the background without having to touch filepaths or files.
• el.timers: Async timer classes such as IntervalTimer and WDTimer for use with asyncio
• el.time_utils: Utilities for working with dates and times
• el.errors: More exception types for general errors I have encountered to need often. Some of them are used by el.
• el.typing_tools: Utility functions for working with typing
• el.numbers: Mathematical utilities for working with numbers, such as linear mapping.
• el.containers: Utilities for working with container objects

UI

• el.ctk_utils: Utility functions and classes for working with customtkinter
• el.widgets: Additional customtkinter widgets
• el.tkml: Tkinter Markup Language: A more user-friendly way to define hierarchical UI with Tk/CTk widgets
• el.mpl_utils: Utilities for working with matplotlib
• el.assets: UI assest manager and some built-in assets

Debugging/Development

• el.analysis: Utilities for analyzing code performance
• el.nixos_ctk_font_fix: Module to work around issues when using CTk on NixOS (not intended for production)

Experimental

These might not be fully implemented (yet).

• el.history_manager (experimental): Utility to manage history of pydantic model instances for implementing Undo/Redo functionality

Contribution

Despite all these disclaimers, if you have utilities, changes, fixes, etc. that you think might be nice to include here, feel free to create issues/PRs.
