mrxbuilder

Work in progress! Almost finished.

mrxbuilder (Mutant Remix builder) is an emoji pack build tool. Takes in a TOML manifest and SVGs and outputs an emoji pack in various formats.

• Completely emoji pack agnostic with no hard-coded assumptions
• Lightning fast and multithreaded, no temporary files written to disk
• Cache friendly, only re-encodes what is necessary
• No runtime depdendencies
• Cross-platform, with prebuilt binaries for Linux, Windows and Mac OS

If you are moving from orxporter, check out the manifest porter repository for a tool to semi-automatically convert your orx manifest to the new format.

Features

• Recolors emojis using colormaps to avoid repeating SVGs with different colors
• Supports building to svg, png, avif and webp formats with various compression methods
• Outputs to a directory or directly to a zip/tar file with various compression methods
• Really simple to run with only 3 arguments. Formats are pre-defined in the manifest, and selected for building using tags

Manifest

Check out the documentation and sample input for input manifest and output metadata specifications and examples.

Usage

This guide assumes general familiarity with the command line. mrxbuilder has no GUI, but there is not

mrxbuilder is run from the command line. It takes 3-4 arguments:

• path to the index manifest file
• output path (cache is also stored here)
• tags for the targets to build (comma separated)
• --dry flag to skip writing any files

Prebuilt binaries

Download a prebuilt binary for your platform from the releases page

./mrxbuilder-v*-* ./sample-input/index.toml ./output debug,release [--dry]

Manual build

Clone the repository

git clone https://github.com/mutant-remix/mrxbuilder

Dependencies

• Basic build tools
• Rust toolchain
• nasm (for building rav1e)

Windows 10+

Note: You can use WSL instead

winget install -e --id=Rustlang.Rustup
winget install -e --id=NASM.NASM

# Command prompt
setx PATH "%PATH%;%USERPROFILE%\AppData\Local\bin\NASM\nasm.exe"
# Powershell
$env:Path += ";%USERPROFILE%\AppData\Local\bin\NASM\nasm.exe"

# Restart your terminal
rustup default stable
# Restart your terminal again

Debian-based Linux (Ubuntu, Pop!_OS, etc.)

apt install build-essential nasm curl
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh # select 1

Arch-based Linux (Arch, Manjaro, etc.)

pacman -Sy base-devel rustup nasm
rustup default stable

Alpine Linux

apk add build-base rustup nasm
rustup-init # select 1

Mac OS

brew install nasm curl
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh # select 1

Build and run

cargo run --release -- ./sample-input/index.toml ./out debug,release [--dry]

# or use mold for faster builds (linux only, optional)
mold -run cargo run --release -- ./sample-input/index.toml ./out debug,release [--dry]

Note: Do not run it without the --release flag, as it will be extremely slow.

Future plans

• Support for more formats, such as jpeg-xl
• Support for writing EXIF metadata and svg metadata. help wanted
• Support for fonts. help wanted
