# 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`, `TOML`, `XML`, `INI`, or `Properties` configurations, mould provides a fast, Vim-inspired workflow to get your environment ready.
|
|
|
|
## Features
|
|
|
|
- **Universal Format Support**: Handle `.env`, `JSON`, `YAML`, `TOML`, `XML`, `INI`, and `Properties` seamlessly.
|
|
- **Tree View Navigation**: Edit nested data structures in a beautiful, depth-colored tree view.
|
|
- **Smart Template Discovery**: Rule-based resolver automatically discovers relationships (e.g., `.env.example` vs `.env`, `config.template.properties` vs `config.properties`) and highlights differences.
|
|
- **Strict Type Preservation**: Intelligently preserves data types (integers, booleans, strings) during edit-save cycles, ensuring your configuration stays valid.
|
|
- **Add Missing Keys**: Instantly pull missing keys and their default values from your template into your active configuration with a single keystroke.
|
|
- **Neovim Integration**: Comes with a built-in Neovim plugin for seamless in-editor configuration management.
|
|
- **Docker Compose Integration**: Automatically generate `docker-compose.override.yml` from `docker-compose.yml`.
|
|
- **Vim-inspired Workflow**: Navigate with `j`/`k`, `gg`/`G`, edit with `i`, search with `/`, and save with `:w`.
|
|
- **Modern UI**: A polished, rounded interface featuring a semantic Catppuccin Mocha palette.
|
|
- **Highly Configurable**: Customize keybindings and semantic themes via a simple TOML configuration.

|
## Installation
|
|
|
|
### CLI Application
|
|
Ensure you have Rust and Cargo installed, then run:
|
|
|
|
```sh
|
|
cargo install --path .
|
|
```
|
|
|
|
Alternatively, you can build from source:
|
|
|
|
```sh
|
|
git clone <repository_url>
|
|
cd mould
|
|
cargo build --release
|
|
```
|
|
|
|
### Neovim Plugin
|
|
If you use a plugin manager like `mini.deps`, you can add the repository directly:
|
|
|
|
```lua
|
|
add({
|
|
source = 'https://git.narl.io/nvrl/mould-rs',
|
|
checkout = 'main',
|
|
})
|
|
```
|
|
|
|
## Usage
|
|
|
|
Provide an input template file to start editing. `mould` is smart enough to figure out if it's looking at a template or an active file, and will search for its counterpart to provide diffing.
|
|
|
|
```sh
|
|
mould .env.example
|
|
mould docker-compose.yml
|
|
mould config.template.json -o config.json
|
|
```
|
|
|
|

## Configuration
|
|
|
|
mould can be configured using a `config.toml` file located in your user configuration directory (e.g., `~/.config/mould/config.toml` on Linux/macOS).
|
|
|
|
Example configuration:
|
|
|
|
```toml
|
|
[keybinds]
|
|
down = "j"
|
|
up = "k"
|
|
edit = "i"
|
|
save = ":w"
|
|
quit = ":q"
|
|
normal_mode = "Esc"
|
|
search = "/"
|
|
next_match = "n"
|
|
previous_match = "N"
|
|
jump_top = "gg"
|
|
jump_bottom = "G"
|
|
|
|
