Installation

D2Grid can be installed from PyPI:

# With pipx
pipx install d2grid

Usage

Once installed, run the tool by passing it the path to your configuration file:

d2grid settings.json

Alternatively, you can execute the script without an installation:

uvx d2grid settings.json

Or run from the source directly:

# With uv
uv run -m src.d2grid settings.json

# With python (need to install python and dependencies)
python3 -m src.d2grid settings.json

Configuration

The tool is controlled by a single JSON settings file. Here is an example for reference:

{
    "globals": {
        "file_source": "hero_grid_config.json",
        "stratz_api_key": "YOUR STRATZ API KEY"
    },
    "result_paths": ["new_hero_grid_config.json"],
    "configs": [
        {
            "name": "Main Grid",
            "columns": [
                { "x": 0.0, "width": 316.0, "width_heroes": 6 },
                { "x": 320, "width": 214, "width_heroes": 4 }
            ],
            "row_gap": 21.5,
            "categories": [
                {
                    "name": "Strength",
                    "source": "attr",
                    "param": "str"
                },
                {
                    "name": "My Custom List",
                    "source": "inline",
                    "param": [1, 2, 3, 14, 56]
                },
                {
                    "name": "Sync from File",
                    "source": "file",
                    "param": { "config": "Fav", "category": 4 }
                },
                {
                    "name": "15 best supports (10 days)",
                    "source": "stratz",
                    "param": {"top": 15, "days": 10, "positions": ["POSITION_4", "POSITION_5"]}
                },
                {
                    "name": "Spectral.gg Core Meta",
                    "source": "spectral",
                    "param": { "top": 12, "position": "P1" }
                }
            ]
        }
    ]
}

The script will create new_hero_grid_config.json containing a single Main Grid layout with five categories distributed across two columns.

Columns control the horizontal layout with automatic vertical sizing based on the number of heroes in each category. The heroes within each category are determined by the specified sources and parameters.

A single settings file can define multiple configs (layouts), each with as many categories as needed.

Dota stores its hero grid configuration at <STEAM_PATH>/userdata/<STEAMID>/570/remote/hero_grid_config.json, which can be used as the path for file_source or result_paths.

The full configuration schema can be printed with the following command:

d2grid --schema
