EntryPoint

class EntryPoint

A representation of an entry point as a dataclass. Instances have the following attributes and methods:

group: str

The name of the entry point group (e.g., "console_scripts")

name: str

The name of the entry point

module: str

The module portion of the attribute reference (the part before the colon)

attr: str | None

The attribute/object portion of the attribute reference (the part after the colon), or None if not specified

extras: tuple[str, ...]

Extras required for the entry point

load() -> Any

Returns the object referred to by the entry point

to_line() -> str

Returns the representation of the entry point as a line in entry_points.txt, i.e., a line of the form name = module:attr [extras]

EntryPointSet

EntryPointSet = dict[str, dict[str, EntryPoint]]

An alias for the return type of load() & loads() and the argument type of dump() & dumps(). Entry points are organized into a dict that maps group names to sub-dicts that map entry point names to EntryPoint instances.

load()

entry_points_txt.load(fp: IO[str]) -> EntryPointSet

Parse a file-like object as an entry_points.txt-format file and return the results.

For example, the following input:

[console_scripts]
foo = package.__main__:main
bar = package.cli:klass.attr

[thingy.extension]
quux = package.thingy [xtr]

would be parsed as:

{
    "console_scripts": {
        "foo": EntryPoint(group="console_scripts", name="foo", module="package.__main__", attr="main", extras=()),
        "bar": EntryPoint(group="console_scripts", name="bar", module="package.cli", attr="klass.attr", extras=()),
    },
    "thingy.extension": {
        "quux": EntryPoint(group="thingy.extension", name="quux", module="package.thingy", attr=None, extras=("xtr",)),
    },
}

loads()

entry_points_txt.loads(s: str) -> EntryPointSet

Like load(), but reads from a string instead of a filehandle

dump()

entry_points_txt.dump(eps: EntryPointSet, fp: IO[str]) -> None

Write a collection of entry points to a file-like object in entry_points.txt format. A ValueError is raised and nothing is written if the group or name key under which an EntryPoint is located does not match its group or name attribute.

dumps()

entry_points_txt.dumps(eps: EntryPointSet) -> str

Like dump(), but returns a string instead of writing to a filehandle

dump_list()

entry_points_txt.dump_list(eps: Iterable[EntryPoint], fp: IO[str]) -> None

Write an iterable of entry points to a file-like object in entry_points.txt format. If two or more entry points have the same group & name, only the last one will be output.

dumps_list()

entry_points_txt.dumps_list(eps: Iterable[EntryPoint]) -> str

Like dump_list(), but returns a string instead of writing to a filehandle

ParseError

class ParseError(ValueError)

Exception raised by load() or loads() when given invalid input
