pixi.toml

# Pixi development environment for mplhep
#
# We use a standalone pixi.toml instead of embedding in pyproject.toml because
# pixi doesn't properly evaluate PEP 508 environment markers in dependencies.
# The pyproject.toml has markers like `python_version < '3.10'` which pixi
# tries to satisfy simultaneously, causing resolution failures.
#
# Tracking issues:
#   https://github.com/prefix-dev/pixi/issues/1259
#   https://github.com/prefix-dev/pixi/issues/3724
#
# Usage:
#   pixi install && pixi run test

# _descent_from_layout relies on the mpl>=3.11 Text._get_layout return
# format, and postinstall's `pip install --no-deps` skips dependency checks.
