py-rattler-build
Python bindings for Rattler-Build, the fast conda package builder.
py-rattler-build lets you build, inspect, test, and upload conda packages
directly from Python — no subprocess calls needed.
Quick start
Build a package from a recipe
from rattler_build import Stage0Recipe, VariantConfig
recipe = Stage0Recipe.from_file("recipe.yaml")
results = recipe.run_build()
for result in results:
print(f"Built {result.name} {result.version} in {result.build_time:.1f}s")
for pkg in result.packages:
print(f" {pkg}")
Render and build with variants
from rattler_build import Stage0Recipe, VariantConfig
recipe = Stage0Recipe.from_file("recipe.yaml")
rendered_variants = recipe.render(VariantConfig())
for variant in rendered_variants:
result = variant.run_build()
Inspect an already built package
from rattler_build import Package
pkg = Package.from_file("mypackage-1.0.0-py312h0_0.conda")
print(f"{pkg.name} {pkg.version} ({pkg.platform})")
print(f"Dependencies: {pkg.depends}")
print(f"Files: {len(pkg.files)}")
Test a package
from rattler_build import Package
pkg = Package.from_file("mypackage-1.0.0-py312h0_0.conda")
results = pkg.run_tests()
Generate a recipe from PyPI
from rattler_build import generate_pypi_recipe
recipe_yaml = generate_pypi_recipe("requests", version="2.31.0")
print(recipe_yaml)
Build with progress reporting
from rattler_build import Stage0Recipe, VariantConfig
from rattler_build.progress import RichProgressCallback
recipe = Stage0Recipe.from_file("recipe.yaml")
rendered_variants = recipe.render(VariantConfig())
for variant in rendered_variants:
with RichProgressCallback(show_logs=True) as callback:
result = variant.run_build(progress_callback=callback)
