- class Inventory(source=None, plaintext=None, zlib=None, fname_plain=None, fname_zlib=None, dict_json=None, url=None, count_error=True)
Entire contents of an objects.inv inventory.
All information is stored internally as
str
, even if imported from abytes
source.All arguments except count_error are used to specify the source from which the
Inventory
contents are to be populated. At most ONE of these source arguments may be other thanNone
.The count_error argument is only relevant to the dict_json source type.
Equality comparisons between
Inventory
instances will returnTrue
ifproject
,version
, and all contents ofobjects
are identical, even if the instances were created from different sources:>>> inv1 = soi.Inventory( ... url="https://sphobjinv.readthedocs.io/en/latest/objects.inv" ... ) >>> inv2 = soi.Inventory(inv1.data_file()) >>> inv1 is inv2 False >>> inv1 == inv2 True
Changed in version 2.1: Previously, an
Inventory
instance would compare equal only to itself.source
The
Inventory
will attempt to parse the indicated source object as each of the below types in sequence, except for url.This argument is included mainly as a convenience feature for use in interactive sessions, as invocations of the following form implicitly populate source, as the first positional argument:
>>> inv = Inventory(src_obj)
In most cases, for clarity it is recommended that programmatic instantiation of
Inventory
objects utilize the below format-specific arguments.plaintext
Object is to be parsed as the UTF-8
bytes
plaintext contents of an objects.inv inventory.zlib
Object is to be parsed as the UTF-8
bytes
zlib-compressed contents of an objects.inv inventory.fname_plain
fname_zlib
dict_json
Object is a
dict
containing the contents of an objects.inv inventory, conforming to the JSON schema ofschema.json_schema
.If count_error is passed as
True
, then aValueError
is raised if the number of objects found in thedict
does not match the value associated with its count key. If count_error is passed asFalse
, an object count mismatch is ignored.url
Object is a
str
URL to a zlib-compressed objects.inv file. Any URL type supported byurllib.request
SHOULD work; only http: and file: have been directly tested, however.No authentication is supported at this time.
Members
- property count
Count of objects currently in inventory.
- data_file(*, expand=False, contract=False)
Generate a plaintext objects.inv as UTF-8
bytes
.bytes
is used here as the output type since the most common use cases are anticipated to be either (1) dumping to file viasphobjinv.fileops.writebytes()
or (2) compressing viasphobjinv.zlib.compress()
, both of which takebytes
input.Calling with both expand and contract as
True
is invalid.- Parameters
- Returns
b –
bytes
– Inventory in plaintext objects.inv format- Raises
ValueError – If both expand and contract are
True
- header_preamble = '# Sphinx inventory version 2'
Preamble line for v2 objects.inv header
- header_project = '# Project: {project}'
Project line
str.format()
template for objects.inv header
- header_version = '# Version: {version}'
Version line
str.format()
template for objects.inv header
- header_zlib = '# The remainder of this file is compressed using zlib.'
zlib compression line for v2 objects.inv header
- json_dict(expand=False, contract=False)
Generate a flat
dict
representation of the inventory.The returned
dict
matches the schema ofsphobjinv.schema.json_schema
.Calling with both expand and contract as
True
is invalid.
- objects
list
ofDataObjStr
representing the data objects of the inventory. Can be edited directly to change the inventory contents. Undefined/random behavior/errors will result if the type of the elements is anything other thanDataObjStr
.
- property objects_rst
list
of objects formatted in astr
reST-like representation.The format of each
str
in thelist
is given bydata.SuperDataObj.rst_fmt
.
- source_type
SourceTypes
Enum
value indicating the type of source from which the instance was generated.
- suggest(name, *, thresh=50, with_index=False, with_score=False)
Suggest objects in the inventory to match a name.
suggest()
makes use of the edit-distance scoring libraryfuzzywuzzy
to identify potential matches to the given name within the inventory. The search is performed over thelist
ofstr
generated byobjects_rst()
.thresh defines the minimum
fuzzywuzzy
match quality (an integer ranging from 0 to 100) required for a given object to be included in the results list. Can be any float value, but best results are generally obtained with values between 50 and 80, depending on the number of objects in the inventory, the confidence of the user in the match between name and the object(s) of interest, and the desired fidelity of the search results to name.This functionality is provided by the ‘suggest’ subparser of the command-line interface.
- Parameters
name –
str
– Object name forfuzzywuzzy
pattern matchingthresh –
float
–fuzzywuzzy
match quality thresholdwith_index –
bool
– Include with each matched name its index withinInventory.objects
with_score –
bool
– Include with each matched name itsfuzzywuzzy
match quality score
- Returns
res_l –
list
If both with_index and with_score are
False
, members are thestr
SuperDataObj.as_rst()
representations of matching objects.If either is
True
, members aretuple
s of the indicated match results:with_index == True: (as_rst, index)
with_score == True: (as_rst, score)
with_index == with_score == True: (as_rst, score, index)
