porydex

porydex is a simple utility for exporting data from pokeemerald-expansion for use in a custom Pokémon Showdown Pokédex for your fan-game. Additionally, it provides a modified version of the official Pokémon Showdown Pokédex as a base for extracted data.

Thanks to the original Pokémon Showdown Pokédex for the base implementation.

Requirements

• python >= 3.10.6
• one of the following C compilers:
  • arm-none-eabi-gcc (tested: v13.2.1)
  • clang (tested: v15.0)
  • gcc (tested: v14.1.1)

Setup

Setup is simple; run the following commands:

make setup
source .venv/bin/activate

Usage

usage: porydex [-h] {config,extract} ...

generate data exports from pokeemerald-expansion for showdown dex

positional arguments:
  {config,extract}
    config          setup configuration options for porydex
    extract         run data extraction

options:
  -h, --help        show this help message and exit

config

porydex is configurable according to your system. By default, it assumes the following options:

• Your expansion repository is located at ../pokeemerald-expansion
• Your compiler is invoked by the command gcc
• Your desired directory for output files is ./out

If any of these are not true, use the config set command to update them to the proper values:

usage: porydex config set [-h] [-e EXPANSION] [-c COMPILER] [-o OUTPUT] [-f {json,showdown}] [-i INCLUDED_SPECIES_FILE] [-a CUSTOM_ABILITY_DEFS]

options:
  -h, --help            show this help message and exit
  -e EXPANSION, --expansion EXPANSION
                        path to the root of your pokeemerald-expansion repository; default: ../pokeemerald-expansion
  -c COMPILER, --compiler COMPILER
                        command for or path to the compiler to be used for pre-processing; default: gcc
  -o OUTPUT, --output OUTPUT
                        path to output directory for extracted data files; default: ./out
  -f {json,showdown}, --format {json,showdown}
                        format for output files
  -i INCLUDED_SPECIES_FILE, --included-species-file INCLUDED_SPECIES_FILE
                        text file describing species to be included in the pokedex
  -a CUSTOM_ABILITY_DEFS, --custom-ability-defs CUSTOM_ABILITY_DEFS
                        JSON file describing custom ability definitions and descriptions for a Showdown Dex

Configuration is persisted in porydex.ini; to view configured options, either view porydex.ini via your favorite text editor, or use the config show command.

Specifying Obtainable Pokemon

Your game may not give a player access to all species of Pokémon. In such cases, you can specify a text-file of obtainable species using config set --included-species-file. This file is expected to be a text-based list with one entry per line and each entry being the name of an available Pokémon using Showdown-recognized names, e.g.,

Bulbasaur
Ivysaur
Venusaur
Venusaur-Mega
Venusaur-Gmax
...

Specifying Descriptions for Custom Abilities

vanilla/abilities.json specifies the latest version of the data file used by the official Showdown Pokédex for ability descriptions. For abilities which already exist in a vanilla Expansion repository, this file can be edited to modify those descriptions. If there are custom abilities in your game, then you will need to specify a file with those ability names and descriptions using config set --custom-ability-defs. The provided file should be in JSON format and adhere to the following schema:

{
    "<NAME OF ABILITY>": {
        "desc": "<LONG-FORM DESCRIPTION>",
        "short": "<SHORT-FORM DESCRIPTION>"
    }
}

If short is not provided, then the value for desc will be used instead. To illustrate with an ability in the vanilla Expansion:

{
    "Aerilate": {
        "desc": "This Pokemon's Normal-type moves become Flying-type moves and have their power multiplied by 1.2. This effect comes after other effects that change a move's type, but before Ion Deluge and Electrify's effects.",
        "short": "This Pokemon's Normal-type moves become Flying type and have 1.2x power."
    }
}

extract

Extraction with porydex is easy; just run:

porydex extract

And that's it! Your output data files will be located in the configured output directory.

porydex maintains a cache of pre-processed files that it parses from your repository. If you need to reload this cache -- e.g., if you make a change to any of the files that it reads -- then you will need to force it to reload the cache:

porydex extract --reload
