data – Loaded data from asset

Return type

bytes

keys()

List all files available to be loaded.

Yields

name (str) – Name of a file which can be accessed.

namespaced(namespace)

Return a resolver which changes the root of the resolver by an added namespace.

get(key)
keys()

List the available files in the repository.

Returns

keys – Keys available to the resolved.

Return type

iterable

namespaced(namespace)

Return a “sub-resolver” with a root namespace.

Returns

resolver – Namespaced resolver.

Return type

Resolver

write(name, data)
property zipped

  • opened zip file

  • locally saved zip file

  • retrieve zip file and saved

class trimesh.resolvers.Resolver(*args, **kwargs)

Bases: ABC

abstract __init__(*args, **kwargs)
abstract get(key)
abstract namespaced(namespace)
abstract write(name, data)
class trimesh.resolvers.WebResolver(url)

Bases: Resolver

Resolve assets from a remote URL.

__init__(url)

Returns

resolver – With sub-url: https://example.com/{namespace}

Return type

class trimesh.resolvers.ZipResolver(archive=None, namespace=None)

Bases: Resolver

Resolve files inside a ZIP archive.

__init__(archive=None, namespace=None)

Resolve files inside a ZIP archive as loaded by trimesh.util.decompress

Parameters

  • archive (dict) – Contains resources as file object

  • namespace (None or str) – If passed will only show keys that start with this value and this substring must be removed for any get calls.

export()

Export the contents of the current archive as a ZIP file.

Returns

compressed – Compressed data in ZIP format.

Return type

bytes

get(name)

Get an asset from the ZIP archive.

Parameters

name (str) – Name of the asset

Returns

data – Loaded data from asset

Return type

bytes

keys()

Get the available keys in the current archive.

Returns

keys – Keys in the current archive.

Return type

iterable

namespaced(namespace)

Return a “sub-resolver” with a root namespace.

Parameters

namespace (str) – The root of the key to clip off, i.e. if this resolver has key a/b/c you can get ‘a/b/c’ with resolver.namespaced(‘a/b’).get(‘c’)

Returns

resolver – Namespaced resolver.

Return type

Resolver

write(key, value)

Store a value in the current archive.

Parameters

  • key (hashable) – Key to store data under.

  • value (str, bytes, file-like) – Value to store.

trimesh.resolvers.nearby_names(name, namespace=None)

Try to find nearby variants of a specified name.

Parameters

name (str) – Initial name.
