## Usage
### ED Template
1. **Initialize a new project:**
```bash
nix flake init -t github:dwinkler1/np#ed
```
2. **Enter development environment:**
```bash
nix develop
# or with direnv
echo "use flake" > .envrc && direnv allow
```
3. **Start editing:**
```bash
vv # Launch Neovim
updateR # Update R packages (when R is enabled)
cowsay "Hello!" # Fun utility included
```
4. **Enable languages:**
Edit `flake.nix` and change `false` to `true` in the `cats` section:
```nix
cats = {
python = true; # Enable Python support
r = true; # Enable R support
julia = true; # Enable Julia support
};
```
### RDE Template
1. **Initialize a new project:**
```bash
nix flake init -t github:dwinkler1/np#rde

# ED Template - Simple Editor Environment
A lightweight, customizable Neovim-based development environment with optional language support for Python, R, Julia, and Nix.
## Features
- ✨ **Lightweight**: Minimal configuration, fast startup
- 🔧 **Configurable**: Enable only the languages you need
- 📦 **Reproducible**: Nix-based environment management
- 🎨 **Themed**: Beautiful Kanagawa colorscheme (customizable)
- 🔔 **Notifications**: Mini-notify plugin for user feedback
## Quick Start
```bash
# Initialize a new project with the ED template
nix flake init -t github:dwinkler1/np#ed
# Enter the development environment
nix develop
# Launch Neovim
vv
```
## Configuration
The ED template uses a centralized configuration structure at the top of `flake.nix`:
```nix
cats = {
clickhouse = false;
gitPlugins = false;
julia = false;
lua = false;
markdown = false;
nix = true; # Enabled by default
optional = false;
python = false;
r = false;
};
```
### Enabling Languages
To enable support for a specific language, edit `flake.nix` and set the corresponding cat to `true`:
#### Python
```nix
cats = {
python = true;
# ... other settings
};
```
Includes: Python 3, duckdb, polars packages by default
#### R
```nix
cats = {
r = true;
# ... other settings
};
```
Includes: fixest package by default
#### Julia
```nix
cats = {
julia = true;
# ... other settings
};
```
Includes: StatsBase package by default
### Custom Package Files
You can specify additional packages by creating these files in your project:
- `python-packages.nix` - Additional Python packages
```nix
p: with p; [
numpy
pandas
# ... more packages
]
```
- `r-packages.nix` - Additional R packages
```nix
p: with p.rPackages; [
ggplot2
dplyr
# ... more packages
]
```
- `julia-packages.nix` - Additional Julia packages
```nix
[
"DataFrames"
"Plots"
# ... more packages
]
```
## Available Commands
### Neovim
- `vv` - Launch Neovim (custom binary name)
- `vv --headless` - Run Neovim in headless mode for scripting
### Utilities
- `updateR` - Update R package snapshots from rstats-on-nix
- `cowsay` - Fun ASCII art text formatter (included as example)
## Customization
### Binary Name
The default binary name is `vv`. To change it, edit the `binName` in `flake.nix`:
```nix
binName = "myeditor"; # Changes command from 'vv' to 'myeditor'
```
### Colorscheme
Change the colorscheme in the settings section:
```nix
settings = {
colorscheme = "kanagawa"; # or "gruvbox", "tokyonight", etc.
background = "dark"; # or "light"
# ...
};
```
### Extra Packages
Add more system packages in the `extraPackages` section:
```nix
extraPackages = with pkgs; [
cowsay
ripgrep
fd
# ... more packages
];
```
### Welcome Message
The template includes a welcome notification. Customize it in the `specs.extraLua` section:
```nix
config = ''
require("mini.notify").setup()
vim.notify = MiniNotify.make_notify()
vim.notify("Welcome to ${name}!")
'';
```
## Environment Variables
The template sets the following environment variables:
- `IS_PROJECT_EDITOR=1` - Indicates you're in the project editor environment
- `R_LIBS_USER=./.nvimcom` - Project-local R package directory
## Language Package Management
### Replace vs Merge
By default, language packages are **replaced** rather than merged with base packages. This is controlled by:
```nix
let
replace = pkgs.lib.mkForce;
in {
lang_packages = {
python = replace ([...]); # Replaces base packages
r = replace ([...]); # Replaces base packages
julia = replace ([...]); # Replaces base packages
};
}
```
To **merge** with base packages instead, remove the `replace` wrapper:
```nix
lang_packages = {
python = (with pkgs.python3Packages; [...]);
# ...
};
```
## Development Shell
The development shell provides access to the Neovim package plus additional utilities:
```bash
nix develop # Enter the dev shell
```
Available in dev shell:
- `vv` - The configured Neovim
- `updateR` - Update R packages (when R support is enabled)
- All packages listed in `extraPackages`
## Testing
The ED template has comprehensive CI/CD tests:
### Automated Tests (`.github/workflows/check_ed.yml`)
1. **Basic Tests** (Ubuntu)
- Build verification
- Flake check
- Dev shell entry
- Neovim launch and version check
- Utility commands availability
2. **Language-Specific Tests**
- Python configuration: Package imports, code execution
- R configuration: Package loading, code execution
- Julia configuration: Version check, code execution
- Multi-language: All languages enabled together
3. **macOS Tests** (`.github/workflows/check_macos.yml`)
- Build verification on macOS
- Basic functionality tests
## Tips
1. **Use direnv for automatic environment loading:**
```bash
echo "use flake" > .envrc
direnv allow
```
2. **Pin specific package versions** by editing `flake.lock`:
```bash
nix flake update # Update all inputs
nix flake lock --update-input nixpkgs # Update specific input
```
3. **Check what's included in your build:**
```bash
nix path-info -Sh ./result
```
4. **Build for different platforms:**
```bash
nix build .#packages.x86_64-linux.default
nix build .#packages.aarch64-darwin.default
```
## Comparison with RDE Template
| Feature | ED Template | RDE Template |
|---------|-------------|--------------|
| **Complexity** | Lightweight | Comprehensive |
| **Binary Name** | `vv` | `p` |
| **Project Structure** | Manual | `p-initProject` command |
| **Language Support** | Optional (Python, R, Julia, Nix) | Built-in (R default, Python/Julia optional) |
| **Research Tools** | None | Quarto, Marimo, Pluto.jl |
| **Package Management** | updateR | p-updateDeps (comprehensive) |
| **Use Case** | Simple editing, lightweight projects | Research, data science, complex projects |
