# mould
|
|
|
|
mould is a modern Terminal User Interface (TUI) tool designed for interactively generating and editing configuration files from templates. Whether you are setting up a `.env` file from an example, creating a `docker-compose.override.yml`, or editing nested `JSON`, `YAML`, or `TOML` configurations, mould provides a fast, Vim-inspired workflow to get your environment ready.
|
|
|
|
## Features
|
|
|
|
- **Universal Format Support**: Handle `.env`, `JSON`, `YAML`, and `TOML` seamlessly.
|
|
- **Hierarchical Flattening**: Edit nested data structures (JSON, YAML, TOML) in a flat, searchable list.
|
|
- **Docker Compose Integration**: Automatically generate `docker-compose.override.yml` from `docker-compose.yml`.
|
|
- **Vim-inspired Workflow**: Navigate with `j`/`k`, edit with `i`, and save with `:w`.
|
|
- **Modern UI**: A polished, rounded interface featuring the Catppuccin Mocha palette.
|
|
- **Highly Configurable**: Customize keybindings and themes via a simple TOML configuration.
|
|
- **Dynamic Alignment**: Automatically aligns keys and values for perfect vertical readability.
|
|
- **Default Value Visibility**: Keep track of original template values while editing.
|
|
- **Incremental Merging**: Load existing values from an output file to continue where you left off.
|
|
|
|
